2020 Honda Pilot Collision Avoidance Problems

Your forward collision avoidance system is activating unpredictably—the brake warning light comes on, the gas pedal applies braking force, and the collision warning stays lit on your dashboard. The camera behind the windshield mirror appears to be malfunctioning and triggers braking at random times regardless of whether a vehicle is actually nearby, which is concerning when driving at highway speeds around other cars. The fix will likely involve diagnosing and recalibrating or replacing the forward-facing camera and its associated sensor system.

On or about January 7, 2026, we were driving through town and the dash cluster lit up with five separate warnings for safety features no longer operational. These are adaptive cruise control, lane keeping assist, collision mitigation, road departure mitigation, and automatic high beams. We cleaned the windshield and radar housing.

Lane Assist Camera Failure (Part #36160-TG7-A63) Vehicle Information: Make/Model/Year: 2020 Honda Pilot EX-L Failed Component: Lane Assist Camera, Part #36160-TG7-A63 Safety Issue Description: The lane assist camera has failed, disabling multiple critical safety systems, including: Adaptive Cruise Control Lane Keeping Assist Collision Mitigation Braking System Road Departure Mitigation Auto High-Beam System Concern: This camera component is not subject to normal wear and tear, being housed within the vehicle's protected interior near the rearview mirror.

Turned car on one day and warning lights on dash. ACC problem, Collision mitigation system problem, road departure mitigation problem, LKAS, Auto high beam, CMBS problem. Prior there were no issues Took car to dealership and they determined its the forward looking camera U3000-49, see uploaded file.

Upon startup I frequently get the following warnings: -Collision Mitigation System Problem -Road Departure Mitigation System Problem -Adaptive Cruise Control Problem -Lane Keeping Assist Problem -Braking System Error All mechanical systems work fine but cruise control and all of the “smart” safety features don’t work.

I am a retired car dealer and have driven hundreds of different cars but have never had this happen before and Honda tells me it is normal which I know is not the case! when I am driving on any kind of road flat or hilly when opposing traffic is on coming, the yellow light flashes and beeps and occasionally the steering wheel also vibrates.

Collision Mitigation System proble

In late December of 2023, our 2020 Honda Pilot began showing a "brake system" warning light, as well as numerous dashboard warnings indicating that automatic cruise control, lane keeping assist, collision mitigation, automatic high beam, and lane departure were not functioning properly. Our local Honda dealer diagnosed the vehicle as having a multipurpose camera failure.

While driving the vehicle, all the aforementioned systems came on the cars dashboard stating that all of them have been turned off, and now there is a brake system issue with the vehicle. The car has 35000 miles and has not been in any accident or collision.

I was driving at low highway speeds when the Collision Mitigation Breaking System had a malfunction and became disabled while driving in traffic. There was an audible alert and visual alerts which popped up and became a distraction while driving as it was sudden unknown what was happening and if the car was safe to drive. I was able to continue to drive home.

The sensors alerted me to Brake in an emergent flash and then slammed the brakes - when there was nothing in front of me. It happens when the car is going faster than 45 MPH. It has happened on three separate occasions and the third time almost caused an accident on a two lane road traveling 55 MPH

as I am driving down a 2 lane road( the road can be flat or hilly or curve right or left) the brake warning light comes on falsely when a car is approaching me from the opposite way and the brake warning light displays and sometimes it shakes the wheel. this falsely is indicating that I am needing to brake to avoid a collision when there is NOT an chance at a collision is going to happen.

The contact owns a 2020 Honda Pilot. The contact stated while driving at various speeds, the message "Brake" was displayed, and the vehicle shuddered while there was no vehicles or objects in front of the vehicle.

I just bought this vehicle yesterday. While driving it home the front collision breaking system came on twice. There were no other vehicles, pedestrians, animals, or objects on the road.

The radio and other components of the "mostbus network" fail constantly (radio, rear entertainment and Blu-ray drive, in dash meter, amplifier). The rear view camera frequently fails to activate when switched to reverse gear. The car will also frequently give a forward collision warning and occasionally slam on the brakes even where there are no other cars in sight.

Our Honda Pilot displays and shakes the wheel for Forward Collision Warnings a minimum of 30 times a day over approximately 32 miles daily. The vehicle has on more than one occasion engaged the Collision Mitigation Braking System (CMBS) as well in situations where no vehicle was on the road ahead or beside us, nearly causing us to be rear ended at high speeds.

The auto emergency braking (forward collision mitigation) will trigger and brake hard frequently on 2 lane roads. This has surprised me multiple times. Honda service says that this is normal and they don't seem interested in fixing it.

Vehicle brakes automatically when operating at highway speeds when passing a vehicle that is either moving slowly or stopped in a turn lane waiting to turn left. Occurs when Collision Mitigation System is in both the on and off position and when cruise control is engaged and disengaged. This has occurred approximately twice a month since purchasing new in July of 2020.

We purchased a 2020 Honda Pilot EXL AWD. The collision mitigation system engages arbitrarily, no vehicles or obstacles in front of me and the system activates. Honda Dealership said they can't find a problem.

False collision warnings and fails to alert to actual potential collisions. Alerts and reacts to non-existent collisions causing unnecessary anxiety and reactions by driver. Speeds vary from 35 MPH to 60+.

Your rear view camera has stopped working, and the repair costs $2,000. This appears to be affecting multiple owners and may warrant a safety recall investigation.

Your car's collision avoidance system is detecting obstacles that aren't actually there and automatically applying the brakes, even when the road ahead is clear. This happens unexpectedly while driving at highway speeds, creating a serious safety hazard.

Your car displayed multiple warning lights on the dashboard indicating problems with adaptive cruise control (ACC), lane keeping assist (LKAS), collision mitigation, road departure mitigation, and auto high-beam features. After diagnostics at a Honda dealership, the issue was traced to an internal failure in the multi-purpose camera unit that handles these safety features. The camera replacement and recalibration should resolve all of these warning lights and restore these safety systems to normal operation.

Multiple safety features on your vehicle stopped working at the same time: lane-keeping assist, adaptive cruise control, automatic high beams, forward collision warning, and automatic braking all failed and their warning lights came on. This appears to be a widespread issue affecting other 2020 Honda Pilots. The fix will likely involve diagnosing the camera or sensor system that these features depend on, which may require recalibration or replacement of the front-mounted camera or related sensors.

The ADAS camera had an internal failure, rendering all of the driver assistance features inoperable. The camera was the one that came from the car new. The old camera is available for inspection.

My vehicle activates CMBS randomly. There doesn't even have to be cars around me and it'll just lock me up in the middle of the road. I have almost been rear-ended several times now.

Car was park after I drop off wife to work after 30 minutes when back to the car started the engine and several warnings lights showed up in my dash check battery and alternator they are working fine. Replace battery and still have the problem .when to dealership and they told me camera in my windshield is bad.

This malfunction has been described to the dealer (s) on multiple occasions. They stated that is how it functions. I disagree.

This has happened since I bought this vehicle brand new. whenever I am on a 2 lane road, the brake warning light and brake warning chime activate fairly often but intermittent when traffic coming from the opposite direction. if I am on a 4 lane road and in the lane that is closest to the oncoming traffic , it will send a false brake warning and brake warning chime.

The automatic emergency braking system will sometimes just start flashing as if there is an object in front of me. There are no objects in front of me and it would flash. There has been 2 occasions where the vehicle would slam on the brakes and then release even though no objects are on the road.

CMBS activates for no reason whatsoever. I can't even count how many times this vehicle has locked the brakes up and no cars anywhere near me at all. Like miles down the road.

Drive car normal .park car went in building to work. After work start cart and on highway going home all lights came on on dashboard. Mechanic said front camera is burnt due to excessive heat.

Vehicle braking randomly. Cars can be nowhere in sight and this vehicle will slam the brakes. I have almost been rear-ended several times and almost ended up in a road rage incident due to this vehicle slamming the brakes.

Events happened about 5 times in 3weeks , car will flash brake , brake brake and steering wheel will shake for no reason

Automatic Emergency Braking engaged while I was driving on the highway with no cars and no warning brake light on dash. There were no cars in front me ( this is the second time). Periodically the Braking light flashes on the dash if I’m driving on a two way road in the curve part of the road.

My Honda often displays the brakes warning and on rear occasion apply brake in response to oncoming traffic on two-lane roads. I already went with onboard camera recalibration at one of the safe glass location but this problem persist on narrow two-lane roads.
