2023 RAM 1500 engine problems

ENGINE

The truck has done this four times since 01/22/2026. While still moving slowly the truck will do this while going down the highway. One other safety issue was when I merged into traffic on the highway (You have to merge into the fast lane at this location) the truck wouldn't go past 4th gear approximately 40 mph with cars coming up on me at 70. All of these problems correct when I can get the truck restarted.

ENGINE

First incident, vehicle completely lost power and turned off while driving down highway, fortunately I was able to coast in to shoulder and request a tow. Second event the vehicle flashed all warning lights while traveling down interstate and had a quick shudder. This was similar to first incident. However, lights eventually cleared themselves and power wasn’t lost. Third incident vehicle warning lights flashed on and lost power. Eventually restarted and drove to dealership. Mechanic visually witnessed vehicle lose power again while in inspection bay. Engine control module was replaced during visit. Two weeks later, vehicle failed to start again with same symptoms of all the warning lights and check engine lights being on. Vehicle was able to start next day and was driven straight to dealership where it currently sits. These repeated and spontaneous engine failures, including when driving at highway speeds, are an extreme risk to my life and the life of others and are unacceptable for a vehicle with 45,000 miles.

Driving down the highway in heavy traffic and the truck shutoff unexpectedly, I came to a complete stop and luckily avoided being rear ended and had to go from Drive and Park and recycle the ignition to restart the truck and limp off to a safe place.

ENGINE

When slowing down in traffic or approaching a stop sign vehicle will stall then turn off. This will than cause the vehicle to abruptly stop. Emergency brake is then engaged. It takes 1-3 times to engage vehicle to restart using the push start button. This happens with in 2-4 blocks of a cold start or even after 15 minutes or more of driving. This vehicle has been in the Dodge dealer several times with them not able to duplicate problem. This happens several times a month. Have been told by dealer it does NOT show a "code" for them to locate problem. When vehicle stalls it puts emergency brake on and alternator light comes on. After vehicle is re started you must pull over and turn vehicle off for few minutes to get alternator light to turn off. Volume of gas in tank seems to have NO bearing on when this vehicle stalls. This vehicle stalling happens more frequently when outside temperature is 50° and above. Happens more frequently with warmer temperatures

ENGINE

Etorque and battery failure. Etorque was failing and coldbrook Mitsubishi said it was fine. 2 months later brought to Lee dodge/ram and told etorque bearing gone. By now 80k manufacturer warranty over 80k and not warranted despite me telling them before this mileage. This etorque should be recalled and paid for. This truck has been nothing but problems. I won’t buy anything from stelantis in the future!

ENGINE

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.

ENGINE

2023 Ram 1500 V6 eTorque, 40,000 miles. Two stalling incidents have occurred under different conditions. Incident 1: While towing approximately 4,000 lbs, the 12V battery began slowly draining while the vehicle was in motion. Battery voltage gradually dropped below 10 volts until the engine shut off completely while driving. No warning lights appeared prior to shutdown. Jump start restored normal operation. Stored fault codes retrieved afterward showed 16 simultaneous voltage fault codes across every major module including ECU, ABS, EPS, DDM, PDM, CSWM, IFC, PTS and SCCM — all logging system voltage below allowable range simultaneously, consistent with a complete charging system failure. PCM also logged a U0401 code indicating implausible data received, consistent with the PCM losing stable voltage. Incident 2: After approximately 45 minutes of low-speed driving (5-10 mph) in a Walmart parking lot, the vehicle stalled without warning on a busy road in [XXX] . My wife and two young children were in car seats in the vehicle at the time. The engine cut off completely in live moving traffic with no warning. I was forced to exit the vehicle and jump start it in the middle of traffic while my children remained strapped in their car seats, creating a serious and dangerous situation. Jump start restored normal operation. On the subsequent highway drive home, battery voltage was observed declining from 14V to 13.2V over the course of the drive, suggesting the charging system is unable to maintain adequate voltage output. This is a known recurring issue with the Ram eTorque mild hybrid system. NHTSA has an open preliminary investigation into eTorque stalling on 2022 Ram 1500 models. The MGU, BPCM and PCM are all covered under the 8-year/80,000-mile Federal Emissions Warranty verified via VIN. PCM software updates have never been performed on this vehicle. Vehicle is being brought to an authorized Ram dealership for diagnosis and warranty repair. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U

NHTSA complaint #11726471 — an unverified report by a vehicle owner.

ENGINE

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.

ENGINE

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.

ENGINE

While driving at roadway speeds, the vehicle experienced a sudden loss of the instrument cluster and infotainment display, immediately followed by an engine shutdown. Steering and braking assistance were reduced during the event, requiring immediate driver intervention to safely maneuver the vehicle. The failure occurred without warning. No prior warning messages or indicators were visible before the loss of power and instrumentation. After the vehicle coasted and was restarted, all systems appeared to return to normal operation. This condition has occurred more than once and presents a serious safety risk, especially at highway speeds, due to loss of engine power and driver information. The vehicle was taken to an authorized dealership and remained there for over three weeks for inspection. The manufacturer was consulted, but the condition could not be duplicated during testing. No repairs were performed, and the vehicle is being released back to the owner with instructions to drive it until the condition occurs again. The issue has not been resolved, and the vehicle remains susceptible to an unexpected shutdown while driving, which could result in a crash or loss of vehicle control.

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.

NHTSA complaint #11710288 — an unverified report by a vehicle owner.

ENGINE

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.

ENGINE AND ENGINE COOLING:COOLING SYSTEM:RADIATOR ASSEMBLY

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.

I was moving forward about 5 mph to merge on to the main road when the emergency brake engaged, engine shut off, steering wheel locked and the 2023 Ram 1500 stopped blocking traffic. Instrument panel instructed me what to do . This was a dangerous situation especially if I was moving at a greater speed.

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.

ENGINE

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.

ENGINE

On 3 separate occasions the truck has completely broken down while traveling 60-84mph. Each time, while in motion, the check engine and battery lights come on on the gauge cluster. Voltage starts rapidly draining from the battery indicator before systems start being shut down. Fiirst is entertainment, then climate, the ABS, then steering, and then all power and engine loss. I almost lost control the first time while trying to make it safely over to the soft shoulder. Each of the three times this had happened, the truck was completely dead in the side of the road and was towed to a dealership three times. The truck was towed to 2 different dealerships. The first two times to Imperial Dodge where they charged the battery the first time and did a software update the second time. Most recently the truck had been at DCH Temecula, for two weeks, where nothing has been done due to them not being able to recreate this issue. They recommended that I take video, while driving, as the issue happens live. This is a major safety issue in general but unacceptable that the manufacturer and dealerships only solution is for me to put myself and my family in jeopardy, and break California law, to diagnosis this massive unsafe vehicle.

ENGINE

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.

3 times in the last month, my 2023 Ram with only 25000 miles has stalled while I have been driving. The situation was I was in a line of traffic and rolling forward at approximately 5-10 miles per hour when the truck died, auto shifted into park and set the emergency brake. I then immediately hit the start button again and got a low battery voltage warning. I turned the car completely off and on again, then was able to move and continue with the flow of traffic with no faults. I took the truck to the dealership to have it diagnosed and they found that the truck logged a code P032F, which is associated with vehicles stalling. However, they stated they were unable to replicate it and there wasn't a fix currently available. I have also not been able to replicate it and it seems to happen completely at random. My safety and the safety of others was definitely a factor as I was stranded in traffic without the ability to move my vehicle. If I had not responded quickly, it could have caused an accident. Prior to this there were no symptoms of failure, and the truck drives completely normal until the event occurs.

ENGINE

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.

ENGINE

There is a severe throttle delay when pressing the gas pedal in all situations. From a stop to go when you press the throttle there is a severe delay causing a massive safety problem when pulling out / pulling into traffic / merging into a highway or roadway / wven while driving at any speed and you press the pedal there is a huge delay. Its a big safety hazard This is an issue on many ram vehicles from what i am reading on forums and even the dealership has acknowledged the issue but says ram wont resolve it. I am still trying to through ram and the dealership but no luck so far. I believe this is a setup/ programming problem straight from the manufacturer. Please help resolve this before someone gets hurt or killed.

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.

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.

ENGINE

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.

ENGINE

Just before I was completely stopped at a red light, the engine died, the transmission shifted to park, and the emergency brake was set. After several minutes and several attempts, the engine started and I was able to drive it home. The only indication something was wrong was the “Check Engine” light was on. That light was off the next morning. I took it to the local Ram dealer to be checked out. The result of the computer diagnosis was “Nonplausable codes.” They said there was nothing they could do. Our fear was (and remains) is that this might happen again while driving at a higher speed in heavy traffic. That could possibly cause serious injury or death, or both. Due to that serious concern, we took it back to the dealer and ask them to keep it for a while to see if it happened with them. While they had it, different personnel drove it over 400 miles, but the problem was not reproduced. Also, no recall has been issued for this model truck. However, there has been a recall for other models with the Etorque engine because of unexpected stalling. We are concerned every time we drive it. In fact, my wife will not drive it nor take the grandkids anywhere in it.
