2020 Ram 1500 Engine Problems

Your engine failed unexpectedly at 140,000 miles, even though you've kept up with regular dealer maintenance and had an oil change just a month before. A valve broke inside the engine, causing it to stop working, with no warning lights or symptoms beforehand. The repair will likely require engine rebuild or replacement.

Your 2020 Ram 1500's hybrid charging system has failed repeatedly, causing the engine to shut off unexpectedly while driving and cutting off power steering assist—creating a serious safety hazard. The vehicle has also stalled at low speeds and intersections, and your battery dies daily despite recharging. The issue stems from a faulty belt starter generator (BSG) and 48-volt hybrid system components that are currently on national backorder. Fixing this will require replacing the failed BSG unit and associated 48-volt system components.

Your engine is running very rough and idling poorly, with the check engine light turning on. You may also experience engine misfires where the engine runs unevenly, and your vehicle could stall but will restart. A dealer diagnosed this as a failed camshaft that needs to be replaced to restore normal engine operation.

The generator bearings are making a wining noise. It was confirmed by an experienced independent mechanic that the E-torque generator needs replacement. The dealer said the generator is not in stock. Further research showed the part is on back order for months, with thousands of others waiting and in the same boat of no parts available.

This engine has failed by the head gaskets, literally all 4, cracking/breaking. This caused coolant to leak into the engine, mix with the oil, depleating the coolant, thereby causing the truck to overheat and break down. With repairs this continues to happen. 3 times to be exact! This cannot be normal for this engine especially when this happened with less than 90K miles on the engine.

The contact owns a 2020 Ram 1500. The contact stated that while the vehicle was parked or while driving, the contact smelled an abnormal exhaust odor, and there was a rattling sound coming from the exhaust manifolds. A dealer was not contacted. The vehicle was not taken to the dealer or an independent mechanic to be diagnosed or repaired. The manufacturer was notified of the failure and informed the contact that the vehicle was out of warranty. The approximate failure mileage was 56,900.

Smoke leaks into cabin when heat is on. Possibly coolant/heating core. I saw many complaints for the same issue on the internet and figured i would make an official complaint

The e-Torque motor generator unit is failing, rendering the truck unsafe to drive. Catastrophic failure of this unit while in operation would likely cause loss of control. Signs of failure primarily have been increasing noise in the unit common to bearing failure. The component was inspected by an independent service center and confirmed to need immediate replacement. The part is currently unavailable from any source, and the manufacturer reports a back order with no known date of availability.

I leased this vehicle, brand new. I bought out the lease just over a year ago. The truck has under 113,000 miles. I drove the vehicle to New York for a trip. The motor started, knocking, ticking real bad so I pulled into the shop (Monroe) they looked at the engine and said it's blown. They was no waring/check engine light never came on. Gauges were fine (digital). It cost me 16 grand to put a new motor in and dodge will not cover it. The mechanic also stated, he sees these engine blown (V6) all the time in my RAM and in the Durango's.

The contact's mother owns a 2020 Ram 1500. The contact stated that while driving at an undisclosed speed, there was an abnormal knocking sound coming from the vehicle, and the on/off switch and battery low level warning lights were illuminated. The contact drove the vehicle to a nearby parking lot. The contact stated the engine seized while driving at 5 MPH. The contact stated that the failure was due to a failed motor generator unit. The vehicle was towed to the dealer, where it was diagnosed with a failed motor generator unit. The contact was informed that the motor generator unit needed to be replaced. The vehicle was being repaired. The manufacturer was made aware of the failur,e and a case was filed. The failure mileage was approximately 95,000.

Failure of the Motor Generator Unit (MGU). This part is available for inspection and review. The failure of this component can result in complete immobilization of the vehicle which poses a significant safety risk for users and pedestrians alike. The problem has been a wide-spread issue for the Ram 1500 series. This issue was acknowledged by Ram and Stelantis. Ram has reviewed my MGU and confirmed that the component is faulty. The only warning was a whining noise and then the vehicle became completely incapacitated.

I own a 2020 RAM 1500 Big Horn 4WD with the 5.7L HEMI eTorque system. The vehicle began making a whining noise while running. A certified diagnosis confirmed the failure of the engine generator unit, part number 68623194AB, which is required to keep the eTorque system functional. This part has been on nationwide backorder for an extended period with no estimated time of arrival from Mopar or the dealership. The vehicle is currently undriveable and unsafe, and I have not been given a timeline or support for alternative transportation. The unavailability of this critical hybrid powertrain component has made my vehicle unusable for weeks, and I’ve seen numerous reports from other RAM owners experiencing the same issue with no resolution. There is a serious risk to safety and reliability if this continues to be ignored. I am requesting that NHTSA investigate this widespread part shortage and potential manufacturer defect. There should be a recall or mandated parts response for affected vehicles if the manufacturer cannot supply replacement components for a core electrical system.

The contact owns a 2020 Ram 1500. The contact became aware of coolant fluid stains on the ground. The contact stated that while driving 40 MPH, there was an abnormal sound coming from the radiator fan. Upon inspection, the contact noticed that coolant fluid had accumulated on the fender under the radiator. The vehicle was taken to the dealer where it was diagnosed that the radiator seal had failed. The contact was advised that the radiator needed to be replaced. The vehicle was not repaired due to the cost. The contact stated that the failure persisted. The manufacturer was notified of the failure, but no assistance was offered. The failure mileage was approximately 60,000.

Cracked exhaust manifold. I know of three people, besides myself, with the 2020 Ram with 5.7 literally Hemi that have had cracked exhaust manifold. Mopar has a technical service bulletin, but the cost to repair is on me.

Exhaust manifold is ticking after only hitting 47k miles. Of course the warranty has been out for a month now. The dealership won’t cover it quoting me $3,200 to replace both of them.

Due to the recall Z96/NHTSA 22V-767 my fuel pump failed in 2023, causing my check engine light to come on due to a fuel injector warning. The dealership replaced the fuel pump, but nothing else was replaced or checked. In April 2025, my check engine light came back on for a #4 Glow Plug issue. The truck at this point had 56k miles on it, and was out of warranty. I took it to a local mechanic, who found the glow plug had shrapnel on it, causing it to fail. He believes it is due to the high pressure fuel pump failure the previous year, releasing debris into the fuel system. This is a safety issue due to the loss of engine power, and if multiple cylinders are affected could cause the vehicle to go limp.

The contact owns a 2020 Ram 1500. The contact stated while stopped at a traffic light, there was an abnormal rattling sound coming from the engine. The contact pulled over to the right side and attempted to restart the vehicle; however, the vehicle failed to respond. The contact stated that the vehicle was taken to Town and Country Garage. A dealer was contacted. The vehicle was towed to a dealer where it was diagnosed that the engine had failed and needed to be replaced. The vehicle was repaired. The manufacturer was notified of the failure but offered no assistance. The approximate failure mileage was 61,000.

The Alternator Generator (MGU) failed and I was driving on the road when it happened causing the electronics to start going dark one after the other then dark screen and lost power steering. Thank God I was close to the side of the road and rolled out of traffic's way. The truck was towed to the mechanic who confirmed it is the MGU. The problem is that this part is on back order with no ETA. So I have a 2020 RAM Laramie with 39,000 miles only sitting in the shop. If this happened on the highway, an accident would have been guaranteed. I was simply lucky.

The contact owns a 2020 Ram 1500. The contact stated that when the vehicle was started, on several occasions the contact observed an abnormal ticking sound coming from the front of the vehicle. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure. The failure mileage was 80,000.

Smoke, burning smell entering cabin area while driving and using heater. Look up issue, found many people had the same problem involving heater core leaking/failing early.

MGU bearing failing, and no stock available, they suspect it may be months before the part is available

The contact owns a 2020 Ram 1500. The contact stated while driving 55 MPH, the vehicle began to shake violently, after which, the vehicle lost motive power. The engine stability warning light was illuminated. The vehicle was taken to the dealer, who diagnosed a failure with the oil cooler, resulting in damages to the engine. The contact was informed that the engine needed to be replaced. The vehicle was repaired. The manufacturer was notified of the failure, a case was opened, and the contact was referred to the NHTSA Hotline for assistance. The failure mileage was 131,000.

While driving at highway speed (~65-70 mph), the engine shut off unexpectedly (without any warning/bucking). There were no errors displayed on the dashboard. Center screen stated to place vehicle in park before starting. The multimedia console, AC, all other electronic systems in the cab were operating as normal. The truck did not start back up for some time (10-15 mins). The dealer states that there were no codes present in the vehicle's onboard diagnostic system (OBD) that indicate any issues or that the vehicle stalled. This has happened 3 times in less than a month. The truck has about 76,000 miles. It is a 2020 Ram 1500 with 5.7L V8 HEMI MDS VVT eTorque Engine.

The manifold bolts on the Ram 1500 pickups will break causing the manifolds to leak. This happens around 50-60k in mileage.

Both exhaust manifolds are cracked. There is a bulletin on some 5.7 Hemi but not mine. Both have to be replaced. The vehicle is at Central Florida Chrysler Dodge Jeep in Orlando. The engine was making a ticking noise. Not sure where it was coming from.

Manifold leaking which could affect the components around possibly causing the engine to completely shut down. Is the the dodge dealership now. Apparently there are no recalls at this time. We do have an extended warranty on the vehicle thank goodness. All maintenance is up to date on this vehicle. The vehicle is at the dealership now and parts will not be in until October 24. It is not driveable at this time.

Driver and passenger manifolds Have cracked now 3 times on the passenger side and 1 time in the drivers side. Inhale had the last passenger side replaced under warranty and now they will not honor the warranty on the replaced manifold.

Component Failure: Around 45,000 miles, my vehicle equipped with the 5.7L HEMI E-torque V8 had both exhaust manifolds cracked with large exhaust leaks pre-catalytic convertor Safety Risk: My vehicle equipped with the 5.7L HEMI E-torque V8 was idling in a parking lot for around 1 hour while I waited inside the vehicle. Cold ambient temperature with windows up and heater on. I noted having a slight headache and started smelling what seemed to be pre-catalytic convertor exhaust fumes (rich fuel smell). I stepped out of the vehicle and smelled the exhaust at the rear of the vehicle, which did not match. I attributed the smell to a nearby vehicle. One week later, the same event occurred with no other vehicles parked around me. The exhaust leak was large enough to pull exhaust fumes into the cabin through the HVAC system. High risk of carbon monoxide poisoning if the vehicle was to sit long enough, risking both myself and my child's safety while we sat in the vehicle. Problem Reproduced: Yes, brought the vehicle CJDR dealer who diagnosed the vehicle with "both exhaust manifolds cracked" and replaced both exhaust manifolds under warranty. Has component been inspected: Unknown. Parts were removed from vehicle as covered under warranty at dealer and replaced with new parts. Any Warnings: No warning lights on dashboard or DTCs for catalytic convertor performance, lean/rich banks, or other exhaust/emissions related. Exhaust seemed slightly louder on cold start. Smelling of unburnt/pre-cat exhaust fumes that prompted dealer visit.

The exhaust flange bolts are prematurely rusting and breaking on the Exhaust system. This is a truck that has less than 30,000 miles and less than 4 years old. This is a common problem but seems to me RAM is using sub par materials in there bolts and they are failing at an earlier than expected time. These parts should be good for at least 80,000 100,000 Miles. These parts should be covered and a recall should be issued for these bolts as they are failing and braking prematurely. Creating a safety hazard as if the exhaust flange bolts break the pipe would hit the ground and create a safety and or accident hazard.

Exhaust manifold bolts snapping at low milage causing exhaust to possibly leak into the cabin. Most people are getting manifolds resurfaced and replacing the bolt's. If you replace manifold with new, it will warp again and break bolts again. Apparently the manifolds were not “Stress Relieved” in the manufacturing process. Lots of people are complaining and Ram dealers are saying it happens a lot. Cost to fix is approx. $1,000.

The contact's son owns a 2020 Ram 1500. The contact stated that while his son was driving at an undisclosed speed, the vehicle made an abnormally loud sound. The vehicle was taken to an unknown dealer, where it was diagnosed that the exhaust manifold needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure but confirmed that there was no recall associated with the VIN. The failure mileage was 91,189. The VIN was unavailable.

Broken exhaust manifold bolt. Allows exhaust gas to enter engine compartment.

Exhaust Manifolds have cracked twice on the right and once on the left side in the first 45K miles of the vehicles life. Both times replaced under warranty, there appears to be a design defect here that should be resolved. Leaking exhaust manifold in California will violate CARB emission standards.

Both exhaust manifolds cracked creating an exhaust allowing exhaust gases/fumes into the vehicles cabin causing an obvious safety issue. No warnings lights of any sort, the components were inspected by the dealership and confirmed that they were cracked. This is a recurring problem as a quick search about ram exhaust manifolds will provide a never ending list of stories and the dealer themselves stated they are constantly replacing cracked exhaust manifolds everyday and the parts are hard to get due to the issue being so common.

Exhaust manifolds leaking at cylinder heads due to broken manifold bolts.

Truck engine has shut off when coming to a stop or slowing down making a turn. Yes vehicle is available for inspection. Vehicle has stopped in the middle of roadway Problem has happened multiple times, has not been confirmed Vehicle has not been inspected No warning lamps or messages.

Since the vehicle was purchased new in 2020, the check engine light has come on and the service throttle body message has been displayed 12 times. It only happens when I am towing a 5,500 pound travel trailer. When the anomalies happens, I loose engine power. Say I am traveling at 65 MPH. When the anomalies happens and the CEL and warning messages appear, my speed drops to 32 MPH. Most Interstate freeway systems have a 45 MPH lower limit. I am forced to quickly pull over to the emergency lane to avoid a crash situation. If I shut off the engine and restart it, my power comes back but the CEL is still on. The selling dealership has tried to fix this several times. The engine code that is always present is a P00AF (turbo boost control “A” module performance, I think over boost) and at one time a P0299 (turbo under boost). The latter occurred after I heard a loud “whoosh” . The turbo air hose blew off. So far the Dealer has flash programmed the engine control module, replace the turbo hose and lastly replaced the turbo itself. Not all of the anomalies have been documented by the dealer, as I am always traveling around the country when it happens and have called dealers in the city nearest me at the time and have gotten every excuse as to why they cannot look as it now. I am almost always able to resume my travels by shutting off and restarting the engine. When I arrive back home and take it in to be looked at, I’m told there is no codes and no history of a code. It can be several thousand miles after the anomalies when the dealer finally gets to look at it. FCA (Chrysler corp) is aware of the situation and has opened 4 cases for my concern. Case # 77583210 which they immediately closed, # 78338328, #79796818 and just on 06-9-2023 case # 86383024. The vehicle now has 21,726 miles on it and most of them are towing miles. The vehicle specifications state this vehicle can tow 12,000 lbs. I bought this vehicle for vacations and towing. THIS VEHICLE IS UNSAFE!

The contact owns a 2020 Ram 1500. The contact stated that while operating the vehicle, the odor of exhaust fumes was present inside the cabin of the vehicle. Additionally, there was a loud exhaust sound while depressing the accelerator pedal. The local dealer was contacted. The local dealer stated that the failure was due to a crack in the passenger’s side exhaust manifold however, the parts needed to repair the vehicle were on backorder due to a high demand. The manufacturer was notified of the failure, but no assistance was offered. The failure mileage was 43,000

2020 RAM 1500 HEMI Broken manifold bolts had fixed with 34,000 miles now the truck has 40,000 and DO NOT BOTHER CALLING MOPAR. they can care less. said i needed to take to dealer and then call back to see what they can do so I asked the rep how many ram owners have yall helped when they took the truck into a dealer for diagnostic out of warranty? No response- shocker there. I stated that mopar knows about this ongoing issue for years and will not do anything about it . Only to be told that I have to take the truck to a dealer. Where they want to charge a fortune. Something needs to be done about this.

Manifolds. This is an ongoing problem with ram owners. They blow at early mileage and progressively get worse until the fumes are in the cab. This can be extremely dangerous and could cause unconsciousness or even death if it’s bad enough. If someone where to become unconscious behind the wheel, it could put many people at danger.

The contact owns a 2020 Ram 1500. The contact stated that the vehicle was taken to be serviced by an independent mechanic, and the mechanic noticed an abnormal sound coming from the fuel injectors. Additionally, the contact stated that the vehicle was consuming an excessive amount of gasoline in a short period of time. The vehicle was not diagnosed nor repaired by the independent mechanic or the dealer. The manufacturer was not made aware of the failure. The failure mileage was approximately 74,000.

I was making a right turn after being stopped at a light and made it approximately 100 feet before the vehicle just shut off. I was able to steer to the side of the street, stop, and restart the vehicle. I didn’t hear or see anything abnormal but it all happened so far. The dealer is looking at it now (in the next 5-7 days). This is a real safety concern.

The contact owns a 2020 Ram 1500. The contact stated while driving 55 MPH, the engine seized. The contact stated the message “Parking Brake not Engage” and the Push to Start warning light was illuminated. The contact was able to park on the side of the road and fully turn off the vehicle. The contact stated after waiting for a while, the vehicle was restarted but was unable to be turned off. The contact stated the vehicle continued to experience the vehicle. The vehicle was not drivable. The contact took the vehicle to the local dealer. The vehicle was not diagnosed or repaired. The manufacturer had not been informed of the failure. The failure mileage was approximately 30,000.

5.7 V8 right rear exhaust manifold leaks exhaust gases due to broken manifold bolts. Weight of the exhaust header appears to fracture the header bolts causing the leak. Seems to be a common issue for the vehicle.

The contact owns a 2020 Ram 1500. The contact stated that while her husband was driving at a slow speed, the vehicle lost motive power and stalled. The driver opened the door and the alarm engaged. There were no warning lights illuminated. The vehicle was towed to the local dealer where it was diagnosed that the rear electrical wiring harness was corroded, and water had entered the vehicle and damaged the unit. The vehicle was not repaired. The manufacturer was not contacted. The approximate failure mileage was 5,100. The VIN was not available.

The Ram 1500 has a exhaust manifold leak, drives side. Loud noise at start up then quiets down after warming up. The repair parts are on a national backorder. I fear there is a possiblity of fire under the hood (25 years as a firefighter). The truck is parked waiting on a call from the dealer for parts.

Took truck into dealer for 15,000 mile service. Dealer installed software update covered by recall notice. Truck was running like Swiss watch when taken to dealer. Less than 200 miles after retaking possession and in the middle of nowhere, 2 plus miles North of Tonopah Nevada the engine quit leaving us stranded in 106 heat. Policeman took us back to Tonopah after seeing us stranded. Truck taken by flatbed trailer next day to dealer in Fernley, Nevada. It has now been 10 weeks and dealer has not been able to identify problem and get truck engine operating. RAM customer service has spewed nothing but platitudes and refused to buy back truck or render assistance to hard working dealer that will fix engine.

My truck randomly stalls. Sometimes from a stopping position, sometimes at slow speeds. I have taken it to the dealership and they keep saying they can not replicate the problem and they know nothing about this issue despite the fact if you google it, you will see forums full of people having the same issues and the dealerships giving them the same runaround. Today, I almost got broadsided because it completely died when I was pulling out. The other truck had to lock up their brakes and swerve to avoid hitting me in the drivers side which would have caused a major injury to myself. This truck is not safe to drive, yet the dealership keeps telling me their is nothing they can do and I am forced to continue to drive it. I know several people have reported this to your agency also, yet their still is no recall.

Pushed accelerator after a stop sign, heard a pop and immediately lost power and the check engine light came on. Coasted to a parking lot nearby and parked. Discovered the transmission cooling line disconnected spontaneously causing a catastrophic failure. Transmission fluid exploded all over the engine manifold and underneath the vehicle. Smoking ensues. Extremely dangerous to me as I had to power to the vehicle. If traveling on an interstate going highway speeds likely would have been put a great risk personally and to other drivers. Problem confirmed at the dealership after towing. Thought the connection was not made secure at the factory. Only indication after failure of component.

Vehicle engine shuts off unexpectedly while in operation. Can happen in any condition: idling, accelerating, cruising or coasting. If at a slow speed (less than 5mph) vehicle activates emergency breaking then shifts itself into park. Can happen WITH or WITHOUT “Auto Start/Stop” being activated (fuel saver). When emergency breaking enacted, I’ve almost been rear-ended by trailing car. This issue has been reported on driver forums.

HIGH LEVELS OF COPPER IN THE OIL. VEH. HAS 20,400 MILES ON IT. THREE CONSECUTIVE OIL CHANGES WITH OIL ANALYSIS PERFORMED. BEARING FAILURE OCCURRING, OIL PRESSURE HAS DROPPED 4 PSI.WHILE DRIVING FREEWAY SPEEDS. PSI AS LOW AS 28 AT IDLE....

TRUCK FAILS TO PROPERLY ACCELERATE CREATING DANGEROUS MOMENTS WHEN ATTEMPTING TO PULL INTO TRAFFIC.PROBLEM SEEMS TO OCCUR MORE FREQUENT IN WARMER WEATHER BUT IS OCCURRING MORE FREQUENTLY AS MILEAGE ACCUMULATES. THIS ISSUE DID NOT OCCUR IN THE FIRST 3-4000 MILES. BUT NOW OCCURS QUITE FREQUENTLY. WHEN IT HAPPENS THE ACCELERATOR IS FULLY DEPRESSED WITH EXTREMELY SLOW ENGINE ACCELERATION. THE FIRST EXPERIENCE WITH ISSUE A SERVICE ELECTRONIC THROTTLE WARNING DISPLAYED. THE CEL SET AT THAT TIME CLEARED BY ITSELF. DEALER HAS BEEN UNABLE TO DETERMINE CAUSE. THIS PROBLEM SEEMS LIKE IT IS ENGINE & BOOST MANAGEMENT RELATED.

CHECK ENGINE LIGHT CAME ON AT AROUND 300 MILES. CODE P3497. BROUGHT IT TO THE DEALER AND WAS TOLD IT NEEDS NEW LIFTERS. TRUCK WAS IN MOTION ON A CITY STREET WHEN LIGHT CAME ON. *TR

2020 RAM 1500 ECODIESEL HAS A SERIOUS TURBO LAG. WHEN YIELDING AND THEN ACCELERATING, THE ENGINE POWER SEEMS TO JUST DROP OUT, FALLS FLAT. BY THIS TIME VEHICLE COASTS INTO APPROACHING LANES AND THEN IT WILL SUDDENLY ACCELERATE WITH A BURST OF POWER. I FEEL IT IS TURBO LAG BUT MAY ALSO BE THAT THE TRANSMISSION IS NOT DOWN SHIFTING IN TIME IN ADDITION. I'VE HEARD NUMEROUS OTHERS MENTION THIS AND IT'S SOMETHING THAT I HAVE TO WATCH FOR CONSTANTLY BUT CANNOT CATCH IT EVERYTIME. THIS SPECIFICALLY HAPPENS EVERY TIME I GO TO EXIT MY LONG DRIVEWAY ONTO A 4 LANE HWY. *TR

THROTTLE RESPONSE OR ACCELERATION LAG AFTER LETTING OFF THE GAS TO CHANGE LANES OR SLOWING FOR CORNERS ETC. HAS HAPPENED AT END OF EXIT OFF THE INTERSTATE AFTER STOPPING AT STOP SIGN, THEN PROCEEDING TO MAKE A RIGHT TURN INTO THE LANE. UPON PRESSING GAS TRUCK SEEMS TO "COAST" OR WAIT A FEW SECONDS BEFORE REALIZING IT'S GETTING GAS THEN WILL SUDDENLY ACCELERATE. YOU HAVE TO WAIT AND NOT GIVE IT GAS FOR A FEW SECONDS FOR IT TO CATCH UP.THIS CAUSES A PROBLEM WHEN CHANGING LANES IN TOWN IN TRAFFIC. APPEARS TO HAPPEN MAINLY AT SLOWER SPEEDS. SUCH LAG COULD CAUSE YOU TO GET REAR ENDED A LOT CAN HAPPEN IN 3 TO 5 SECONDS. HAVE HAD VEHICLE TO SHOP, INSPECTED AND NO SIGNS OF ANYTHING WRONG UPON TESTING. HAS HAPPENED AGAIN, WILL TAKE TO SHOP AGAIN. THIS HAS HAPPENED 5 OR 6 TIMES NOW IN LESS THAN 30 DAYS OF OWNERSHIP. TRUCK NOW HAS 1078 MILES ON IT. *TR

3.0L GEN 3 ECODIESEL ENGINE HAS EXCESSIVE LAG AND DELAY IN THROTTLE RESPONSE. WHILE TRAVELING AT STEADY SPEED IN LOWER GEARS 3RD, 4TH, OR 5TH AND THEN DEPRESSING ACCELERATOR PEDAL TO INCREASE SPEED, ENGINE WILL NOT RESPOND UNTIL THREE TO FOUR SECONDS HAVE ELAPSED. THIS CREATES A SIGNIFICANT HAZARD WHEN ATTEMPTING TO MERGE INTO TRAFFIC OR CROSS TRAFFIC DURING A LEFT TURN. PRIOR EXPERIENCE WITH MULTIPLE GASOLINE AND DIESEL TURBO-CHARGED VEHICLES HAS NOT PRESENTED THIS ISSUE TO ME. THE 2020 RAM 1500 ECODIESEL HAS A MAGNITUDE OF TURBO LAG AND UNRESPONSIVE THROTTLE THAT IS QUITE DANGEROUS.
