What owners say
2025 Ram 1500 experiences complete engine stalling at low RPM while coasting to stops. First and only owner since June 20, 2025. Vehicle properly maintained. INCIDENTS: August 28, 2026 - stalled twice (12:30 PM at stop sign, 3:30 PM at stop light). Both times coasting with no throttle/brake input. Check engine light appeared. September 17, 2026 - Critical safety incident: Vehicle stalled while releasing brake at stop sign merging with Highway 50 eastbound (50 MPH traffic). Complete loss of power steering and brakes during highway merge. REPAIR ATTEMPTS FAILED: Dropped off September 3, returned September 10 after PCM software update. Stalling returned. Returned September 16-17 for ignition control module update. Vehicle stalled in dealership parking lot same day. Two repair attempts in two weeks - both unsuccessful. DIAGNOSTIC CODES: P0300, P0301, P0302, P0303 (cylinder misfires). Codes persist after both repairs, indicating root cause in ignition/fuel delivery system that software updates cannot fix. SAFETY HAZARD: Vehicle shuts off without warning while operating. Loss of steering/brakes during highway merge created imminent collision risk. Vehicle currently unsafe to drive. REQUEST: Investigate systematic manufacturing/design defect in low RPM stalling condition. Multiple failed repairs and diagnostic codes indicate this is not isolated component failure. Vehicle has defect despite 14 months proper maintenance by first owner. Vehicle also has issues with radio and backup system. Parts on order with no delivery date or repair date.
I bought this used truck with 60K miles on it in 2024. It is a 2020 truck. At 136K the engine failed.........with the infamous [XXX]. I have an excel summary spread sheet on all maintenance I had done since I owned this truck and I did not pull or haul anything. I heard a tick for about 10 days before I took it to my dealer whom I bought it from and they stated after "scoping" that the # 8 cylinder misfired and cylinder wall scored and the lifter pin bearing failed thus cam shaft damaged and exhaust manifold cracked. They had to replace the engine with a remanufactured engine from [XXX] and replaced intake and exhaust Manifold at a cost of $ 15,021 out of my pocket. I was stuck with no options logically. I do not have a problem with the Dealership - [XXX]. I have a problem with Ram Engineering, Stalantis design. To me there is no excuse to have a big cast iron block v-8 fail at 136K miles. There are many more ram owners who have this same problem I just stated that I had. If I knew then what I know now i would have never bought this truck with this 5.7L engine. There were no warnings, messages or anything displayed to alert there was a problem. I expect that there was not enough oil flow to # 8 cylinder ( which is all the way back to the left rear ( passenger side) of the engine ) looking from the front of the truck as I read many Ram forums on line. I changed to oil every 5K miles with Mobil 1 full synthetic oil along with the filter - either Mobil 1 or WIX filters. some of the best on the market. I do not know what I can do now but this is rediculous. I won't get burned again. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
On October 12, 2025, while on the highway, the CEL started blinking and the truck began misfire and shutter. I was able to get to the side of the road where I discovered the truck would idle but would barely move. It was towed to the closest dealership where they attempted to reflash the PCM and ISCM which is associated with Stellantis TSB 08-31025 REV. B. The PCM was flashed but the ISCM needed to be replaced. This was successful for another 9,484 miles where the issue repeated which, I will create another incident for.
I purchased a new 2025 Ram 1500. Within the first week of ownership, the vehicle developed repeated engine misfires, check engine lights, and electrical issues, including a dead battery. The vehicle was repaired multiple times under warranty. The engine later suffered an internal failure that required complete engine replacement. After the engine replacement, the vehicle developed a new drivability problem. The truck now consistently shudders and hesitates during light acceleration and while maintaining a steady speed. The RPM has fluctuated unexpectedly, and the vehicle feels as though it is being fuel starved. This occurs without a check engine light. The dealership’s technician reproduced the condition during a test drive and confirmed the shudder. Stellantis technical support instructed the dealership to replace the mass airflow sensor as the first step in diagnosis but advised that they do not know whether this will correct the problem. I am concerned that the hesitation and shuddering could affect the vehicle’s ability to accelerate safely when merging into traffic, crossing intersections, or passing other vehicles. The vehicle has been out of service for an extended period while diagnosis and repairs continue.
