2023 Ram 1500 Engine Problems

The Auto Start-Stop system is not working properly. Three times it has failed to restart when sitting a traffic light. I believe this is safety issue because I could be rear ended if a vehicle is not aware of my vehicle not starting to move with traffic. The Auto Start-Stop can only be manually stopped by turning it off in the vehicle ever time to start to use it. This system needs fixed or there could be an accident on the road.

I own a Ram 1500 Big Horn that has repeatedly shut off while driving and entered limp mode, causing sudden loss of power and engine shaking. This has occurred both while driving and while stopped at intersections, creating a serious safety hazard in traffic. The vehicle has been taken to the dealership more than nine times for the same issue, but they initially claimed they could not diagnose the problem because no codes were present. The vehicle recently broke down again and the dealership retrieved diagnostic codes P2172, C121C00, B151A100, and U100300, indicating airflow and CAN bus communication issues. Ram ordered an alternator to fix the truck, but the first part received was defective and had to be reordered, further delaying repairs. Despite being a loyal customer since 2019, I have repeatedly received substandard service and temporary fixes from Ram, and the truck remains unsafe and unreliable. The problem is unresolved, and I am concerned this defect could cause the vehicle to stall in traffic and potentially lead to an accident.

Two occurrences where the vehicle stalls when accelerating from a stop, shifts into park, and applies the parking brake. I believe this is the same issue as the PE24018 investigation.

In August of this year while the truck was moving, it just shut off and the parking brake was engaged. I brought it to the dealer and they checked the truck through the computer. They could not find any issues. Just this past Saturday 9/27/2025 while i was backing up into a parking space, the vehicle shut down again in gear and the parking brake was again engaged. I call the Service dept at Gainesville Dodge in Florida and have another appt for a week from tomorrow. The first occurrence was 8/2026 I called another dealership in Starke Florida and spoke to their service dept. They informed me they have had the same issue with other Ram trucks but cannot find the cause. This unexpected shutting down is extremely dangerious! I searched the internet and found this issue is not uncommon. There were many reports of the same issue happening to other owners. Shutting down on a major highway can cause a major accident when this occurs. This needs to be looked into by your agency. Thank you.

I have replaced, via warranty, 3 cylinders that have failed within 10,000 miles of the vehicle. This causes my truck to shutter and not accelerate properly. The shop tells me this has been an ongoing problem, however it is not being addressed by Stalantis. Not requesting to do anything for my situation, however it needs to be investigated.

There have been multiple failures from the injector in multiple cylinders resulting in hesitation and shaking in the vehicles. My understanding is that many of the maintenance shops have had to replace this exact component in many 1500's due to its failure. I was informed that Stellantis has been informed, however refused to issue a recall or redesign the unit. Also, they are not covering it under the power trane warranty, even thought the engine won't run without a fully functioning injector. Yes this is a safety issue because of the hesitation it causes, therefore putting you in harms way when pulling out in traffic.

The vehicle was sold with oversized 35-inch tires but was never recalibrated for speedometer, odometer, or tire pressure monitoring systems. The vehicle’s speedometer reads approximately 7 mph slower than actual speed, making the odometer inaccurate as well. This affects braking, ABS, traction control, and engine timing. The door placard still lists the original 265/70R17 tires, meaning the vehicle no longer meets the safety certification indicated by the label. The dealership did not disclose these modifications. I have had two tire failures due to rubbing and unsafe fitment.

The contact owns a 2023 Ram 1500. The contact stated that while the vehicle was parked, the contact noticed a coolant odor coming from the vehicle. Additionally, the contact noticed a puddle of condensation underneath the front end of the vehicle. The contact stated that the vehicle drove normally and there were no warning lights illuminated. The vehicle was taken a dealer, where it was diagnosed and determined that the radiator was cracked and needed to be replaced. The vehicle was repaired, but the failure reoccurred 6 months later. The vehicle was then taken to the same dealer, where it was diagnosed and determined that the new radiator had cracked and needed to be replaced. The vehicle was not yet repaired. The contact stated that a friend who was a mechanic also inspected the vehicle and stated that the radiator needed to be replaced due to a crack. The manufacturer was notified of the failure. The failure mileage was approximately 52,000.

While driving slowly in stop & go traffic, the engine shuts off unexpectedly, often while the vehicle is moving at a slow speed (e-torque switching from 4 cylinders to 8 upon slight acceleration. The truck additionally applies the emergency brake and the shifter remains in Drive. I have to hit the 4 ways, turn the engine "off", turn the nob to Park, remove the emergency brake, restart the engine, turn nob to Drive, stop the 4 ways and continue driving. It is terrifying on busy city streets during rush hour! Recently, the truck almost stalled when approaching a red light that turned green, it "stumbled" and the entire dashboard blacked out. I've owned this truck since mid-July 2023 & this stalling has happened on five (5) occassions - July 2023, November 2023, May 2024 & twice March 2025. Twice in the last week that included the blacked out dashboard. The stalling is intermittent and neither I nor the dealership repair can duplicate the issue. This is exactly the same issue that the many other Ram 1500 e-torque owners report. I'm terrified that I will be rear-ended & cause a major crash.

I was approaching a 4 way stop when the engine lost power and shutoff. The vehicle auto shifted to park before i was able to come to a complete stop and the steering wheel locked up. I was the only passenger, all doors were closed and i was the only vehicle at the intersection. I was able to powerback on and continue on my way, but i have lost all trust in the vehicle and will be taking it in to the dealership tomorrow morning.

On three occasions now the engine has stalled after stopping for stop sign then attempting to accelerate and continue driving. When this occurs the emergency brake is also self deployed causing a sudden and hard stop. This could lead to a rear end collision and possible injury. Ironically this has happened at the exact same stop sign all three times. There were no warning lamps or any indication at all of any engine issues prior to or after the engine stalling. I have owned the vehicle for 16 months and it has 16k miles on it. The vehicle drives fine after each incident. I am contacting the dealer i purchased the truck from today about this issue. It will be the first time reaching out about this problem.

While coming to a stop, the truck died and immediately set the emergency brakes. I was stopped about 300ft. from stop sign with cars stopped behind me. With the cars behind me honking, I waved them around. Released the brake and restarted the truck. Took the truck to the dealer and they could not reproduce the incident, and it threw no codes. This could be a huge safety concern if it were to happen in traffic.

Engine shut off completely will driving at low speed (20 MPH) on a city street, applied brake to make a left turn, when turn was complete, light came on to put vehicle in park, noticed no RPM and that the engine had stalled. When I cam to a complete stop, the transmission shifted to park and the emergency was set. Engine restarted fine and vehicle continued normally.

Vehicle shuts off and engine stalls at slow speeds, then applies electronic e brake for no reason. I have seen multiple reports online for same issue. Then voltage drops until restarting Vehicle which then resets. Went to dealership and they have found code p032f with no fix.

TRUCK WILL STALL. TRUCK PARKING BRAKES INGAGE. THEN TRUCK BATTERY LIGHT COMES ON. HAVE TO RESTART TRUCK. TAKE OFF PARKING BRAKE. WHEN YOUUCAN GET OUT OF TRAFFIC MUST TURN OFF THEN ON TO REMOVE BATTERY LIGHT THAT IS ON

The contact owns a 2023 Ram 1500. The contact stated that on two occasions while driving approximately 60 MPH, the traction control warning light illuminated and the message "Parking Brake Deactivated" was displayed. The contact stated that during the first failure, the vehicle was pulled over to the side of the road, turned off, restarted the vehicle, and the check engine warning light illuminated. The vehicle was taken to the residence and then to a dealer, where the failure could not be duplicated. During the second occasion, while driving up a bridge, the vehicle lost automotive power and the vehicle decelerated to 28 MPH. The vehicle then coasted down the bridge, and it was pulled over to the side of the road, turned off, and restarted. The check engine warning light became illuminated. The vehicle was parked for several hours during a class, the vehicle was restarted and reset independently, and the warning light was no longer illuminated. The vehicle was taken to a dealer; however, the failure could not be duplicated. The manufacturer was not notified of the failure. The failure mileage was unknown.

Electrical system stops charging, and stalls out the whole truck causing the truck to die in the middle of road and shift into park.

Four times the truck has powered down while driving - all were when slowing to turn. No prior warning lights or out-of-spec conditions - battery level reading normal prior to shutdown. Truck shut down the engine automatically. Restarting the truck prompted the battery light but no check-engine light. Emergency brake auto-deployed, stopping the car. In all cases I was stopped in traffic (most recently while crossing a highway), but no accidents. Truck is currently at dealership for diagnostics - preliminary code investigation appears related to the auto-start system causing the engine to shut down. Per dealer, they require input from RAM engineering.

Vehicle loses power, then shifts to park and applies the parking brake. This has happened several times in different driving scenarios. Once this happens, the battery fault light appears on the dashboard.

While driving and slowing for a traffic light, my 2023 Ram 1500 Limited 4X4 began to immediately slow, and I observed the gear selector engage from drive to park, back to drive and back to park, and engaging the emergency brake. The vehicle ceased operating. I was able to engage the emergency flashers and restart the vehicle. All of this occurred while in traffic. This is the second occurrence. The vehicle has approximately 4000 miles. The first time this occurred I took the vehicle to the dealer. They dealer indicated there was no codes found indicating any trouble of this sort. The first time the vehicle had approximately 1,489 miles (Moss Brothers of San Bernardino, Ca) Invoice #[XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
