2017 Honda Pilot Electrical Problems

While driving my 2017 Honda Pilot Elite, the vehicle has experienced four separate incidents of sudden and complete loss of power, including while traveling at highway speeds and during rush-hour traffic. The engine shuts off without warning, causing the vehicle to stop in traffic. In multiple incidents, the vehicle would not restart for several minutes.

so I have a Honda pilot and have been seeing a light saying that my collision mitigation system is broke so I took it in for a diagnostic which I was charged for which is fine and normal I guess but they told me that the system was broken possibly from just driving through construction zones and this causes phantom braking so I have to get it fixed but they want to charge me for the repairs which from my perspective the customer I shouldn't have to pay for a defect like that that can cause injurie or much worse

Horn stopped working which prevented notice to other car at stop backing up, resulting in a crash. Vehicle started turning itself on in accessory mode, flashing lights, disabling keyless entry and starting the vehicle and smelled of an electrical fire, was unable to disconnect battery due to unpredictable turning on and off at vehicles will.

Twice in the past week my 2017 Honda pilot equipped with the auto start/stop feature completely shuts off at traffic lights. Usually it turns back on but it completely shut down and would not restart at very busy intersections. I was very afraid of being rear ended while I was stuck there at the light, and this is a known issue that Honda has yet to address.

Auto engine idle continues to be problematic. Leaving me stranded in intersections and unable to restart my vehicle for minutes. Today when it happened it turned off my collision detection feature.

Shortly after entering the freeway, the dask lights began to flicker and car started stuttering. Drive for another mile or slow looking to pull over. By that time smoke coming from rhe engine.

This appears to be a known problem with the Honda Pilot with the car auto start/stop feature. The power/engine cuts on and off when trying to start back up. The dealer replaced the battery but after around 6 months it has started again.

I am reporting 2 safety issues in this report, both involving the AUTO STOP/START function in my car. SAFETY ISSUE #1: MALFUNCTIONING AUTO STOP/START (ASS) FUNCTION: At least 4 times during the past 2 months, I have had a serious safety issue with my 2017 Honda Pilot wherein it stalls and is completely inoperable for a short time, while I’m stopped at an intersection.

The engine would not restart at the red light. Start/Stop system was active, came to a red light and the vehicle turned off as normal with my foot on the brake, when the brakes were released the vehicle did not restart and I heard a click sound. I had to manually(push the start button) to completely turn off the car and then press it again to start the car.

When at a red light the engine turns off when you press the brake. When you life you foot it should restart automatically. Multiple times my car has no restarted.

Our 2017 Honda Pilot is having issues with the idle stop feature at a stop light or other standard stops. The engine completely shuts off and all electronics also shut off. It then needs to be placed in park and restarted.

On multiple occasions now my Pilot has completely shut down while the auto-idle is on and I have been unable to restart it quickly. My young children and I have been stuck in traffic multiple times unable to move or get out of the way of oncoming traffic due to this and most recently on 9/16/22 I was almost hit due to be unable to restart my vehicle.

On multiple occasions, the engine idle stop system has failed to restart the engine at an intersection when releasing the brake leaving the car disabled in a dangerous situation. This started after about 20k miles. When it happens the car is fine until brake release.

The auto start/stop on my vehicle doesn't always work. I come to a complete stop, the vehicle turns off and when I pick my foot up off the brake to restart the car sometimes it will stall. There is no warning message or indication whether or not the car is about to stall, it just happens randomly.

we bought April 2021 and 1st issue not even 60 days after purchase, dealer removed warranty without us knowing! We have had problems ever since with warming lights coming on & flashing on multiple occasions, even while traveling @ 50 MPH!. Huge safety issue as the vehicle jolts and then looses power and can't pick up speed and go with flow of traffic!

I have a 2017 Honda Pilot Elite. My car has had issues since I purchased with the stop/start feature and it’s progressively gotten worse. It’s currently failing every day.

I was stopped at a red light. The stop idol engaged and the vehicle did not start when I attempted to make my turn. The instrument panel indicated that I should shift to park.

For several year I've had a problem with the fuel-saving stop-start system on my Honda Pilot. Unless I turn this system off each time I drive it routinely (several times a week) fails to turn back on after making a complete stop, usually at a traffic light or stop sign.

--AUTO ENGINE IDLE STOP SYSTEM. Yes, available for inspection upon request. --SAFETY CONCERN- Engine stalls in the middle of traffic...

The auto start/stop system on the Honda Pilot is failing at intersections causing the car to stall out and be stuck in traffic. Dealer and Honda does not have remedy for this issue. This is a known problem that is well documented by other owners.

While driving I first noticed the radio would shut off- almost like an electric surge (Spring 2021). I brought in to local dealer to assess. Dealer couldn't replicate so was dismissed.

There is a major and potentially dangerous issue with the idle stop/start feature. When the car is at a stop and the engine shuts off (gas saving feature) and sometimes the car will fail to start again, leaving me stranded in the middle of an intersection or whatever road I'm on.

Hello, I was driving down the road and my collision mitigation light quickly flashed on and then went off with no objects in front of me or bad weather or rain. Also, my vehicle felt like it tapped the brakes and the steering wheel slightly jerked a little. It was maybe a half second long and then went back to normal.

When at a stoplight, auto idle causes car to completely stall and shut down and won’t restart unless car turned completely off and try to restart again. This has caused me to be placed in some dangerous situations where I have almost been rear ended from behind. Dealership says that it’s the battery but from hearing from multiple people, this has not fixed the problem.

While driving, I noticed a stall with the speed then I immediately noticed that the shift gear was on N position, apparently the shift gear was pushed accidentally even without pushing the button on the side to change gear. Also, my car kept randomly alarming and with static flashing on the dashboard while on park.

When parked, the car begins to try to turn on. The interior lights flash, systems fire and the battery drains. Twice I was left stranded having to rely on tow trucks, replacing batteries that were still functional and running car continuously in order to not drain it since it is my only car and I needed reliable vehicle to get to my kids.

The Auto Idle will kill the engine at a stoplight and force you to restart the vehicle when the light turns green. It is dangerous, and have caused many near accidents and frustrated drivers.

The camera assembly - monocular unit mounted in front of the rear view mirror just stopped working. It’s responsive for a multitude of safety systems, such as: Automatic Emergency Braking, Collision Mitigation, Lane Departure Warning, Adaptive Cruise Control and Lane Keeping Asst.

On my way to work yesterday, I took my exit and stopped at the light where the idle engine function enabled and then my car completely shut off on its own. It took multiple tries to restart the car. Meanwhile, the light turned green, multiple cars were honking at me, and could have most certainly rear ended me.

While at a red light, the auto idle engine feature completely stalls the vehicle. This has happened more times that I can count at this point. Basically, if I leave the feature on, at some point in route, it will stall.

Few minutes after my wife got home the car alarm began beeping and there was a fire coming from the engine of the car. We called 911 and the fire kept getting bigger. Once the fire department arrived and put out the fire we saw a huge damage on the car.

Electrical issues include keyless entry system failure, auto-lock no longer locking the vehicle as you walk away from it, crash mitigation system failure, radio stations no longer coming in clear. Has happened several times and the dealership says that they have adjusted something but then it happens again.

Keyless start system problem error appearing on dashboard. Vehicle has 47,000 miles on it. Electrical is going haywire in that lights intermittently turn on, all error lights flash on dash and dash tries to boot through various ignition states (accessory mode, idle, etc).

When my 2017 honda pilot touring enters idle stop mode, it has begun to stall when you release the brake to re-engage the engine. This happened first in a parking lot on 6/17/20 when leaving parking area to enter main road. Vehicle shifts into neutral.

This is in regards to the idle stop "feature" of the honda pilot. When the vehicle comes to a full stop, the engine cuts off in order to save fuel like it's supposed to. However, when it is time to move again, the vehicle randomly stalls causing the car to completely turn off.

Car shuts down completely t a stop position and computer readout instructions are to put the car in park and then go thru initial start actions. Purchased car in feb 2019, problem started within days of purchase.

While driving, I received an alert that "some driver assist systems cannot operate." lights indicated that the collision mitigation, and lane departure, and lights were affected. I do not want the collision mitigation system to randomly disable (or any system for that matter). The dealer performed a hard reset on my system and we'll see if it's fixed.

Huge/loud pop of radio, car doesn't beep, is still in drive, but is dead when: stopped but not sure that autostart is on' both times this horrible one happened, it was a very brief press on the breaks (11/5: on freeway; 11/6: at stop sign). Screens on dash popped loudly, and suddenly engine was dead.

Tl* the contact owns a 2017 honda pilot. The contact stated that the vehicle lost power while traveling on an incline. Also, the brake pedal was soft and traveled to the floorboard when being depressed.

Your Pilot's engine stalls at traffic lights and won't restart immediately when the Auto Idle Stop/Start feature engages unexpectedly. Multiple dashboard warning lights come on when this happens, leaving you stuck while traffic backs up behind you. This has occurred several times despite having a new quality battery and two official Honda software recalls performed. The issue appears to persist even after these recalls, suggesting a deeper problem with the Auto Idle Stop/Start system itself.

Your car frequently displays warning messages saying "keyless start system problem" and "brake system problem," which prevents the car from starting. You've owned the vehicle for about a year, and this issue occurs intermittently. The problem likely involves the keyless entry system or brake sensor needing diagnosis and repair.

The contact owns a 2017 Honda Pilot. The contact stated that while his wife was driving approximately 65 MPH on the freeway, the vehicle stalled due to battery failure. There were no warning lights illuminated.

I am reporting a recurring “Keyless Start System Problem” warning on my 2017 Honda Pilot. This is a known and widespread issue affecting 2016–2017 Honda Pilot models, as acknowledged by Honda in Service Bulletin 20-117, which identifies a defect in the push-button start/stop switch assembly.

Auto Start/Stop Issue. I finally experienced what some other members of my family have experienced with this car. My Honda Pilot stalled at a stop light in heavy traffic after the engine was turned off when I stopped at the light using the auto start/stop function.

My Pilot has stalled multiple times at a stop light when the auto stop feature restarts the engine. It seems to happen most frequently when the heat or air conditioning is running as if there is not enough power to restart the engine. I did have the service bulletin software update performed, which seemed to solve the issue initially.

All of the warning lights come on the dashboard, the D for Drive flashes. While driving the vehicle downshifts and stalls and loses power and 75% of the time when you come to a complete stop the car completely stalls, loses power and you have to manually turn the engine off and restart the vehicle.

My 2017 Honda Pilot in 4/2023 I was driving the belt way my hood was bouncing as if it was going to fly off an kill us all and who was behind us in rush hour traffic. I called made appointment with dealer. My son went on line there was a recall for 2017 Pilot for hood problem, but not my VIN # I was very very upset.

My car started sputtering and lost power on the interstate and the dash lit up with warnings while driving. I brought the vehicle home and the code is for a bad camshaft position sensor after only 78,000 miles. That is absurd.

Auto shut down/ restart does not work properly. Car was recalled for this issue and a software update was installed. However, car still will not restart after auto shut off.

After owning 2017 pilot (brand new) for 3 to 4 years, started experiencing intermittent stalling at stops when auto idle engaged. Similar to many other complaints, car would stall out, entering into an accessory mode. At times takes several attempts to restart the car.

With the IDLE function ON, the vehicle fails to start once the engine shuts down. The car suddenly stop and shut off at traffic lights, stop sides. Someone almost hit me 4 times during last month with my kids inside when the car fails to start.

If I do remember to turn off the auto engine idle, the engine will stall at stoplights and will not immediately restart. I have almost been rear-ended several times. It just happened again about two weeks ago.

For the past two years, I have been taking my Honda pilot to a Honda dealership, complaining of the auto shut off feature. I will come to a stop at a stop sign or stop light. The car would do the auto shut off and when I lift my foot from the break for the car to start again, it won’t.

While Stopped at a stoplight the Auto Start/Stop feature stalled the engine. This has happened to us multiple times.

A few months ago, car started alarming randomly. Upon entering vehicle all lights on dashboard were going on and off, screen was going through each system followed by "problem" and repeated clicking heard in steering column and captured on video for 1 minute. This continued for several days but car drove okay.

The contact owns a 2017 Honda Pilot. The contact stated while at a complete stop, the vehicle stalled due to a defect with the Auto STOP/START feature. Several unknown warning lights were illuminated during the failure.

On March 18th, 2023 at 6:30 PM I parked my car and waited for the curbside pick up at a cafe with my 3 girls 6 (my niece) 7, (daughter), and 11 (daughter) years old. The car started blinking all the lights started accelerating by themselves and turned off immediately.

The contact owns a 2017 Honda Pilot. The contact stated while driving approximately 15 MPH and decelerating, the fuel saving feature malfunctioned, causing the vehicle to hesitate and almost stall. The contact was able to drive the vehicle off the road to turn off and restart the vehicle.

Was stopped at a very busy intersection today (2/12) and the vehicle's auto start/stop turned the vehicle off. When the light turned green, I attempted to apply gas and the engine stalled out. Was unable to restart the car again after many retries.

The engine fails to restart on its own from a complete stop at a traffic light or road intersection with the Auto Start/Stop function engaged. //////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////// This is an extremely dangerous vehicle malfunction and needs to be addressed as soon as possible before someone is killed.

My 2017 Pilot Elite has been suffering repeated issues with stalling out / engine not turning back on due to some sort of issue with the stop/start function (which will automatically turn the vehicle off when the break has been suppressed for more than 3 seconds). This is extremely dangerous and has put myself, my family, and others on the road in harm's way on multiple occasions.

Car fails to restart when the engine auto shut off engages. The engine will attempt to restart, but then nothing happens. The car is essentially stalled in traffic.

The automatic start/stop feature sometimes fails to restart the vehicle 2. On a few occasions now I have been stranded at a stoplight trying to restart the vehicle with people trying to navigate around me. I have not have it inspected by the dealer or mechanic yet.

Numerous times the auto stop/start feature has failed to work. When the car tries to start back after the stop/start feature has been engaged, it does not start and will completely turn the car off. All the electronics will flash off and back on.

The auto stop/start feature is defective. It turns off the engine when stopped at red lights, but many times the engine then fails to start again when the gas pedal is pressed when the light is green, and the car stalls. This has left us stalled in intersections many times, and sometime it takes 10-15 minutes before the car starts again.

The car sometimes fails to restart on its own from a complete stop at a traffic light or stop sign with the Auto Start/Stop function engaged. Furthermore, on two recent occasions the car would not start at all after it was turned off to get gas.

The auto-idle system causes the car to stall quite often and poses a major safety hazard. We bought the car brand-new in May 2018. The problem started happening approximately 2 years after buying the car.

The idle stop feature not working properly. Many times the engine will not restart after releasing the brake and pressing the accelerator. This has left me stranded in busy traffic situations including intersections.

Car stalls when auto stop turns back on

Vehicle stalls REPEATEDLY when the automatic anti-idle function is active. Whenever the air conditioning and audio is on and I stop the car, the engine stops (as the anti-idle system is intended to work), then stalls out as the engine restarts. This has been happening for about 2 years and happens almost every time the anti-idle system engages.

The auto idle stop function caused the vehicle to stop running, needing a full shutdown and restart. This happened on busy roadways, and it has happened two times with this vehicle, one time each in different years. I think the first time was in 2021 and the second was definitely in June 2022.

Vehicle stalls in the middle of intersection while attempting to auto restart with the auto on/off feature. This has been happening since we boughe the vehicle new in 2017. Dealer said they could not simulate.

The auto start and stop engine feature leaves the car stalled and unable to restart until multiple attempts. We have been stuck in the middle of a highway multiple times with hazards on trying to restart

I own a 2017 Honda Pilot Touring addition and recently learned there is an investigation on the auto start/stop feature. We have experienced the vehicle stalling too many times to count. However, it does seem to be getting more frequent as the vehicle gets older.

When the car comes to a stop at a light or intersection, the auto-idle function of the engine engages (indicated on dashboard). When you lift your foot off the break, the radio shorts out, the dashboard flashes, and the engine struggles to restart. This happens regularly.

The auto start\stop feature doesn't work and is extremely unsafe and dangerous. I will be sitting at a stop light and when the light turns green I take my foot off the break and the car will completely turn off and error messages will appear.

The contact owns a 2017 Honda Pilot. The Auto START/STOP system failed to operate as designed and the vehicle would stall and had to manually be restarted. The contact stated that occasionally several attempts were needed to restart the vehicle before the vehicle would perform as designed.

On multiple occasions with the auto engine restart engaged, the engine has shut off while stopped at a stoplight and then failed to restart the vehicle upon attempting to go. On some occasions, the power blips but the engine restarts. On other occasions, the power blips and the car stalls, leading to having to fully shut the car down and turn it back on, with a successful restart.

I own a 2017 Honda Pilot Elite, with 65000 miles, that was purchased new. The vehicle has repeatedly stalled at various point of operation. Upon stalling, every light appears to activate on the dashboard.

The auto start/stop is not reliable. I have had three incidents in the past 2 years where if I'm at a light and the car turns off due to the auto stop, it will not restart. I did take it to my dealer and they could not find anything wrong with the battery or any other issue.

Parked in a lot with vehicle at full temp. Quick Stop. Drove vehicle to exit of lot and stopped to wait for a break in traffic.

Vehicle will stall out at an intersection, or stop sign after the auto restart shuts the car off. When I lift my foot off the brake for the gas peddle, the entire car stalls and I get a series of warning lights and messages about shifting the car into gear before restarting. Despite attempts to restart the car, I'm generally stranded for 1-2 mins.

I have taken my car 5 times to the dealership due to it stalling at red lights or when stopped. This happens with the idle engine is engaged. It has almost caused wrecks due to shutting off and not turning back on.

Vehicle randomly does not automatically restart after the auto engine idle stop engages when in stop-and-go traffic or when stopped at an intersection, resulting in a stalled vehicle in the middle of traffic. Takes multiple attempts of hitting the start-stop button to restart the vehicle.

My car keeps stalling after being in the idle engine mode. At intersections waiting to turn left, or sitting in traffic on the freeway, at a 4 way stop, it has happened numerous times in the past year where the engine is in idle mode while my foot is on the brake, and when my foot comes off to switch to gas, the gear shifts to N automatically.

This is a random issue that has now happened 3 times in the past couple of months. When the auto idle system is engaged and going to restart, the car stalls. You are stuck in an intersection, at a light, etc.

In my 2017 Honda Pilot Elite the auto idle stop feature has more frequently failed to restart the vehicle when stopped at a traffic light. This leaves the car stalled in traffic instead of restarting after I take my foot off the brake (which is when the system should be restarting the engine). This failure occurs whether I press the gas pedal or just take my foot off the brake.

I had started noticing the radio clicking on/off at stoplights. After a while, it progressively got worse and noticed the car was also slightly jerking too as the car re-started. I called the dealer and they said they were not familiar with the issue.

My 2017 honda pilot elite is equipped with the auto start/stop "feature". This feature can be disabled, but not permanently - you have to remember to turn it off every time you start the car. Several times over the last few months my car has totally died when I'm at stop lights or intersections.

While stopped the auto stop engages turns off the engine and if the AC is running at that time, instead of the the engine restarting when the gas pedal is engaged, the car stalls and shuts down. Dealer states cannot correct the issue (permanently turn off auto stop). I see multiple complaints so far related to this design error but no action in terms of recalls.

I have 30,000+ miles on my 2017 pilot elite. About a year ago, I started experiencing issues with the auto idel stop feature. I first noticed that the auto idle-stop was hesitating when the engine would start up upon lifting my foot off of the gas.

The 2017 pilot stalls while in operation due to a defect in the auto-off while idle feature. When you depress the brake pedal, the engine will shut off completely and will often not restart as intended when you release the brake. The engine will also shut off if you press the auto-engine-off while idle button to deactivate the idle-off feature if pressed while completely stopped.

Car was fine all day. Parked with the engine shut off for two hours whole I was waiting for my kids. When I picked them up and started the car, it has a warning.

While traveling south on I-95 from baltimore, md to washington d.c., near kenilworth avenue, the engine idle shutoff on my 2017 honda pilot touring engaged when I was forced to stop due to a traffic slowdown. When I took my foot off the brake, instead of restarting as it should have, all of the warning lights came on and the engine stalled.

I was stopped at a stop light and my auto idle kicked in. When I took my foot off of the brake the engine died and wouldn't start back up. I was stuck in the street, blocking traffic.

July of 2019: wife complains the vehicle starts back up under protest from the start stop system when driving in stop and go traffic (more so on hot days) on city streets. Eventually, vehicle intermittently stalls when she tries to resume travel from start stop mode. Vehicle eventually restarts after 120 seconds or more.

About 6 months ago, when my car had less than 30k miles. My car would stall while the car was in "auto idle-stop mode". Initially, I first noticed that the auto idle-stop was hesitating when it would start up.

I noticed that auto idle would randomly turn off and on the cars electricity for a second. Today, after stopping for traffic, the auto idle kicked in and the car stalled in neutral. Warning lights appeared and I tried to follow the instructions to restart the car, but it wouldn't restart.

Have a 2017 honda pilot touring with 39k miles. Usually the car goes into 'accessory' mode when the auto idle stop kicks in but a couple of months ago something new started- I experienced a total stall for the first time, and it has happened 3 more times since. The car turned completely off, but it did not restart automatically.

My wife was driving the vehicle on 09-27-18 and the vehicle lost power, the dash lit up orange, and several warning lights cane on and started beeping. As she attempted to pull over to the side of the road, the issue reset itself, and the vehicle resumed power again. The vehicle was taken to honda for a final repair for transmission issues the following day.

The contact owns a 2017 Honda Pilot. The contact stated that while driving at an undisclosed speed, several unknown warning lights were illuminated. The vehicle was pending an appointment with the dealer.

Auto-idle feature shut off vehicle at a stop and would not restart when light changed. Have to shut off vehicle and start like it was parked. Not safe in city traffic.

Odometer Fraud. The contact purchased a 2017 Honda Pilot. The contact stated that while searching on Carfax ,it was discovered that there was a mileage discrepancy.

Electrical System – Body Control Module The BCM in my 2017 Honda Pilot fails intermittently, causing the alarm to activate randomly, warning lights to flicker, and battery drain. The issue occurs without warning, even while parked or driving, creating distraction and reducing confidence in the vehicle’s safety.

After fixing a few of the recalls, the alarm on my 2017 Honda Pilot would start going off at random times. After several attempted fixes - replacing the key fob batteries, replacing the car battery - the issue has persisted and we noticed a clicking noise coming from the dash. Essentially the car would attempt to turn on without anyone near it.

The alarm kept going off randomly/intermittently. Honda recalled the control unit/alarm/TPMS control unit on Honda Ridgeline bit not on Honda Pilot.

The contact owns a 2017 Honda Pilot. The contact stated that upon coming to a complete stop, the auto idle stop system activated, turning the vehicle off. While attempting to continue driving, the contact became aware that the system had failed to restart the vehicle.

Pilot will shut off at stop signs and red lights. Software update completed in 2023 but issue persists. I shut the “feature” off as soon as I turn car on.

Issue where the headlights would come on intermittently while parked in garage, horn would start going off intermittently, car making noises while sitting parked every few minutes. Appears to be a common issue related to the Keyless Access Control Unit (a.k.a. Smart Power Control Unit).

Engine fails to restart after the engine idle stop shuts off the engine when stopped. It is difficult to restart the engine from this state and creates a safety hazard with the car being disabled for a period of time. It does not happen every time.

The car engine was revving up intermittently, with rough shifting of gears, poor acceleration and 3 of the dashboard malfunction indicator lights activating - emission system, transmission system, and blind spot information system. Car still at dealer.

Vehicle fails to restart after the auto engine idle stops the car. Looks like this is a known issue but the dealer I bought this car from isn't doing anything to fix it.

I have had a problem with my vehicle throwing the same codes for over a year and my mechanic and I could not figure out the problem. Finally he ran a report and showed me that these codes match recalls that should have been done on my vehicle but have not been done.

My 2017 Honda Pilot touring edition stopped suddenly in a busy intersection causing major traffic back up and dangerous situations until police officers showed up to help. I called road service and it would ne over an hour before I could get help. I was unable to place push button in neutral by several means to get out of traffic and with officers help.

The engine start/stop intermittently fails to restart after idle stop. Yes, available for inspection upon request. I am unable to restart my car after an idle stop which causes danger by causing traffic jams and my vehicle to be idle on the road.

I was driving in 80 MPH traffic in and my car instantly lost all power while alarms starting blaring while I was changing lanes. I was unable to brake or to accelerate and had to coast — over 6 lanes of 5:00 traffic to a stop and was lucky we weren’t killed.

For no reason the Alarm is going off randomly the dash lights, interior lights, driving lights and headlights are flashing and loud clicking noises come from the dash. This happens frequently and has been going on for some time. I have had to remove the fuse from the Horn to keep it from waking us up at night which creates a potentially dangerous situation if I forget to plug it back in.

The Control Unit, Smart Power - Honda (38320-TG7-A52) part failed on the vehicle after 50k miles. The issue caused all the lights in the cabin to flicker/click and the alarm to go off intermittently. The alarm could not be shut off.

What component or system failed or malfunctioned, and is it available for inspection upon request? In the past few months (My 23 to current Sept 23) the idle stop system would occasionally not restart when gas was applied. This mostly occurred when stopped for a traffic light and I would have to go through a complete restart procedure taking a good amount of time.

The auto start/stop will intermittently fail to restart the engine from a stop after releasing foot the brake pedal. 2017 model year. In 2022 (4 year old vehicle) the auto start/stop failed to restart on three separate occasions from a stop at traffic lights over the course of one winter month.

I own a 2017 honda pilot ex-l. I keep up with all my maintenance and vehicle mainly has highway miles. Emissions systems problem light has been going on and off for about a month now.

When the vehicle has been shut off, there is an electrical system problem that attempts to re-start the vehicle. the alarm goes off, headlights turn on, the dashboard lights up. This cycles over and over unless you open the hood or a door to "fool" the system.

Beginning in February 2023, around 2AM, my car alarm would sound. Upon inspection, the vehicle dashboard was lit up and clicking relay sounds could be heard from the dashboard. In essence, the car was trying to "start" itself.

Vehicle sitting in driveway on hot day started alarm beeping, headlights and tail lights remained on and dashboard warning lights going on and off as if a poltergeist possesed. Car could not be locked. Depleted car battery resulting in new battery being required.

This vehicle keeps having a "Emissions System Problem" Then other times says "Transmission Temperature Too Hot" I bought and get this serviced at my local dealer. They don't know what the problem is and it goes away after I see them for a couple weeks but the problems come back. They say no problem.

Alarm spontaneously went off while in garage & several indicator lights lit up and repetitive clicking sounds heard. Honda dealership Johnson City, TN diagnosed problem as a faulty body control unit module. I was told I could drive the vehicle and afterward unhook the battery cable to keep the alarm from going off & draining the battery.

Went out to garage and started noticing headlights and running board lights were on, so assumed another household member had opened door to put something in the car which is not common. After this started occurring more often, asked and no one fessed up so started paying closer attention and even opening garage door just to check. After that, started noticing clicking sounds under the hood.

For the past couple of weeks, I have seen an quick error message (flashes and then disappears) and my Pilot has hesitated upon restarting after the auto engine idle stop has engaged at a stop sign. This was a longer hesitation (almost a failure to start) than the typical hesitation I feel when this feature engages.

The alarm has gone off 30 times from 7am this morning to 2pm. I also have a picture of the dashboard lights. About a month ago I took it to the Honda Dealership and they charged me for a bunch of other things and gave it back for it to do it again the same day.

My Pilot is suffering the auto stop/start fault that many others have reported online. The vehicle will sometimes fail to restart from the stopped state, forcing us to manually turn off, and restart the engine. As of this morning, the vehicle permanently reports an "Auto Engine Idle Stop System Problem" error.

Keyless Start System Problem indicator illuminated in driver information display. Error notification is displayed intermittently. Stays on for several drive cycles and then goes off for a bit only to come back on again.

The auto start stop function has failed multiple times on this vehicle in different situations with multiple different drivers. When my mother in law was driving my vehicle with my kids in the car the vehicle would not restart at a stop light in the middle of town with moderately heavy traffic. It took several tries to get the vehicle started again.

Auto-stop feature failed to restart vehicle after auto-stop was engaged at a stop light. When letting off the brake, the auto-stop disengaged, but the vehicle engine failed to start, posing a safety risk as the vehicle did not restart in heavy traffic. This has been reproduced numerous times by the owner, but not by a dealer or independent service center.

Car alarm keeps going off randomly and the electronic dashboard flickers repeatedly while the car is parked. I recently left the car at a parking garage and apparently the alarm was triggered and ran all day - I came back to the car that evening and there was clicking sound coming from the engine (not turned on, of course).

For years the stop and auto-start feature will not restart automatically. Sometimes the entire vehicle itself will shut down, lose, power, then restart by itself. It is more frequent now.

When stopped, the engine idles off but when I go to accelerate, the engine shuts off. This is becoming a safety issue as the last two times were on a highway although it is really always a safety issue. Last year the dealer had me get a new battery.

The contact owns a 2017 Honda Pilot. The contact stated that alarm on the vehicle would activate erroneously. The contact stated that after deactivating the alarm, the alarm sounded again hours later.

The problem is linked directly to the Auto Start/Stop capability. The Car is available for inspection upon request. Car shut down electrically in the intersection of the road and caused traffic and police presence, semi trucks rolling through were frightening 3.

We own a Honda Pilot 2017 Touring trim. I saw your news report that there is a document out there published by the NHTSA that is investigating this issue. I’d like to add my experience to this.

In support of NHTSA Action Number: PE22005 2017 Honda Pilot multiple experiences with the auto idle cutting off and not restarting. 8/4/2022 was worst experience to date. The vehicle cut off at a stop light and would not restart.

Starting in the summer if 2020 every few weeks after coming to a stop and the auto idle stop would stop the engine. When releasing the brake the engine would not immediately restart. The pause on restart would slowly increase as the time between occurrences decreased.

The Auto Start/Stop feature on my 2017 Honda Pilot has had issues for the last 2 year. It started with the engine occasionally "hesitating" to restart after I held the brake pedal down at a stop light. As it started to happen more frequently, I took it to my Honda dealer and they told me that they could not recreate the issue and thus could not diagnose and fix it.

When auto idle is engaged, the car SHOULD start when the brake is released after stopping. We noticed problems when we released the brake. The radio and A/C shut down and quickly come back on again.

Issue: engine sometimes does not start after engine idle stop activates On several occasions while stopped at traffic lights the engine failed to start requiring the driver to turn the vehicle off then back on. This occurs after the engine idle stop actives. When the engine stops electrical components, such as the radio, momentarily lose power.

The Idle/Stop function stopped operating at a stop light. The car completely shut off. My wife pressed the brake and ignition but the car did not immediately restart.

The auto stop/start feature does not always restart the car when I release the brake after stopping. Mostly in town at stop signs and red lights but recently it happened while I was in stop and go traffic on an interstate. At all locations I was blocking traffic (flashers on of course) and hoping no one hit me while I sat for a few minutes trying to restart my car.

Multiple times the vehicle has shutoff when the it has reached a complete stop at a traffic light and has not restarted on its own. Took it to dealer but they could not recreate it supposedly. In addition fuel pump issues and the Honda dealer is not able to obtain parts to the fix the vehicle.

When parked, the car anti-theft alarms will honk loudly waking up everyone noisily; the headlights will be turn on & keep running (even if it is manually turned off); the dashboard lights will be flickering; relays clicking; and sometimes the car will turn itself on. The noise & lights can't be turned off from the keyfob.

The auto Start-Stop function is not working properly. In several occasions when the engine stops at a red light the engine will not start again. This has caused many dangerous situations as we got stuck in the middle of an intersection.

Our 2017 pilot tries to turn on by itself, with the electronics in the dashboard starting and engine compartment relays firing, along with the exterior lights turning on without any driver being present or attempting to start the car. It happens even without the keys being present. As a result, the battery drains while the car is parked.

When the vehicle is off, there's a clicking sound and the dashboard turns off and on randomly as if it's possessed. Also, the air bag lights go on. It does this even when the car is completely off.

When stopped long enough to engage the auto idle function the car does not always recover immediately to drive. The car completely shuts down and usually restarts. This has occurred a few times in the past couple weeks and I have been trying to capture it on video to show the dealership.

The problem is that periodically, the engine will not start back up when we are ready to go.

Stopping the full electrical system turns on then off. This happened at traffic lights in the city, on a hill with stop sign in san francisco or city, it also happens in drive through basically whenever you stop from a moving motion. The dash information system flashes and flickers, the pilot then has to be put into park and push start button to turn the motor back on.

At apprx 50k miles (march 2020), display panel intermittently indicated "keyless start system problem" and now (sept 2020) that error code is constant. For a few days recently the error code disappeared, but it came back... The code shows when you start the car.

The engine with shuts off normally when I come to a stop when I have the system engaged. The problems begin when I take my foot off the break expecting the engine to start up again.

After owning the brand new vehicle for about a year, the radio and lights started turning off when the car would start back up at a stop sign/light.

Every few days we get a indicator that reads 'keyless start system problem'. Have replaced the battery in fobs, no change. Indicator comes on when starting the vehicle & stays on until turned off, may or may not come back the next time starting it.

This is the 4th time now that we have had to bring out pilot in to be serviced for the same thing. When we turn the car on, multiple errors come on out of nowhere. Power steering, the speedometer and many other things stop working.
