2022 Ram 1500 TRX problems

“The truck has stalled twice while in motion. Leaving me stopped suddenly in middle of the street. This has happened on 2 separate occasions. I did not think to save the dates. Initially I thought maybe I wasnt giving it enough throttle, but after reading more into it I see there was a recall for the previous year model and this may be considered problematic as well. The truck made me apply the brake to restart, and release the emergency brake since it applied on its own. The first stall I had to turn sharp and fast to try getting to the side of the road to make room for coming and going traffic and avoid being in a collision. The second stall I was luckily the only driver on the road at the time. I'm reading it could be the MGU system and I have also noticed my battery voltage starting to fluctuate more. I jave not taken to the dealer yet as this is my means of transportation for work and we are a 1 income family of 4. I do not get a rental if I have to leave the truck at the dealer.”

“I am reporting a recurring engine defect involving the Multi-Displacement System (MDS) in my 2022 RAM 1500 Big Horn equipped with the 5.7L HEMI eTorque engine. Since purchasing the vehicle in March 2023 with approximately 4,555 miles, the truck has experienced four separate MDS-related failures despite multiple repair attempts by authorized RAM dealerships. On February 7, 2025, at approximately 38,115 miles, a RAM dealership diagnosed an MDS solenoid that had physically separated and required extraction and replacement. On May 1, 2026, at approximately 66,149 miles, another authorized dealership diagnosed an MDS failure involving cylinder No. 1 and performed repairs under warranty. Despite these repairs, the engine experienced another serious failure at approximately 73,000 miles. The most recent failure involved metal contamination and catastrophic internal engine damage, leaving the vehicle completely inoperable. I am concerned that the repeated MDS-related failures indicate a potential defect in the engine's cylinder-deactivation or valvetrain components. Failures involving these components may cause significant engine damage and potentially result in an…”

“The vehicle experienced a sudden powertrain failure at a busy intersection failing to automatically restart during an auto start/stop cycle on October 6, 2026. Upon manual override, the mild hybrid motor generator unit (MGU failed to adequately charge the 48V/12V electrical systems. This failure leaves the driver highly vulnerable to a total high-speed vehicle stall in active traffic due to rapid battery depletion. The manufacturer and dealership is unlawfully denying federal coverage for this emissions/hybrid component. At the time of the incident the vehicle had approximately 59,248 miles on it. I called the dealership (as I believed this would be covered under the 60,000 mile powertrain warranty) that day describing the failure. The earliest appointment I could get was October 16th. By the time my truck went in for the appointment the mileage was 60,130 miles. The dealership Identified the failure as the charging system for the Ram Hemi E-Torques motor. Specifically the Serpentine Belt Tensioner Part #: 05281543AD, 05281956AA, and 68518738AA. Also prescribed a software update. The total quote for the repairs was 1534.80. The dealership denied warranty…”

“My car just stopped and turned off. On the screen it says service electronic stability control. And power steering unavailable and service immediately. I serviced the car on April 24th. I received the car April 29th and they said they had to flash the computers and it would take 1.5 hours. I paid 330 dollars. I drove the car off and 15-20 min later the car cut off. I called the dealership and told them and they said they have to get the car back in the shop. I have additional documents.”

“For the 6th time this year. I was going to take off from stopped when I went to accelerate and my truck shut off, showed switch to park. When I went to apply my brakes. It automatically engages the parking break while moving. This time. A vehicle near rear ended me with my kids in the car due to the abrupt halt. Truck had a full tank. Seat belts were worn. Just engine dying and slamming itself into park. I’ve been searching and seen lots of complaints about similar models and no recall for the 2022 1500. This is becoming a reoccurring issue that is endangering the safety of my children”

“On XXX at approximately 1:00 PM, while driving my 2022 Ram 1500 3.0L EcoDiesel on [XXX] east of [XXX]/north of [XXX], a rigid metal diesel fuel supply tube fractured at approximately 49,209 miles. The failure caused a substantial uncontrolled release of diesel fuel into the engine compartment and underneath the vehicle. Diesel fuel traveled underneath the truck and contaminated portions of the rear of the vehicle. The vehicle's check engine light came on, became disabled and required repair away from home. The failed component has been retained. Photographs show a visible crack/fracture in the metal tube itself rather than at a threaded connection. A replacement Mopar tube was obtained from a Ram dealer. The vehicle previously underwent the Ram/Stellantis high-pressure fuel pump (HPFP) safety recall, Recall 01A/NHTSA 23V-263, on XXX. I do not currently know whether the failed tube was replaced or disturbed during that repair and have requested the prior repair records. I am reporting this because a sudden pressurized diesel fuel leak into the engine compartment presents a potential fire hazard. I have retained the failed component and can make it available for inspection.”
