2022 Ram 1500 electrical problems

Filed Oct 29, 2026 · Electrical, Transmission · ID

Incident 2 of 2: I am filing two separate formal complaints regarding two incidents in which my 2022 Ram 1500 eTorque unexpectedly shut down while driving, posing serious safety risks and raising concerns about an unresolved vehicle defect. Second Incident: May 30–June 23, 2026-While traveling on a mountain road, my truck again shut down unexpectedly. Without cell service, I was unable to call for assistance. After approximately 15 minutes, I restarted the truck and drove home. The following day, the truck would not start, requiring a tow to another Ram service facility. Although the dealership again focused on the 48-volt battery, it could not confirm the cause of either shutdown. I was told a failed fuse prevented the truck from starting, but no underlying cause was identified. Repeated, unexplained failures present an unacceptable safety risk to me, my family, and other motorists. I continue to drive with the concern that my truck could shut down in traffic or in a remote location, potentially resulting in serious injury or loss of life. The approaching expiration of the 48-volt battery warranty further compounds my concerns, as I could face significant repair costs for a problem that remains unresolved. I respectfully urge the federal safety agency to investigate these incidents and determine whether they indicate a broader safety defect requiring corrective action. I believe repeated failures and inability to identify the cause warrants serious regulatory attention before another event occurs.

Incident 1 or 2. I am filing two separate formal complaints regarding two incidents in which my 2022 Ram 1500 eTorque unexpectedly shut down while driving, posing serious safety risks and raising concerns about an unresolved vehicle defect. First Incident: XXX-During rush-hour traffic on a major [XXX] highway, my truck suddenly shut down while I was traveling in the far-left lane. I had to maneuver onto the left shoulder to avoid being struck by another vehicle. After waiting approximately 30 minutes for a tow truck, I was without my vehicle for nearly six weeks while the service center assessed the problem and awaited parts. Repairs included replacing the 12-volt battery at my expense and the 48-volt battery under warranty. Repeated, unexplained failures present an unacceptable safety risk to me, my family, and other motorists. I continue to drive with the concern that my truck could shut down in traffic or in a remote location, potentially resulting in serious injury or loss of life. The approaching expiration of the 48-volt battery warranty further compounds my concerns, as I could face significant repair costs for a problem that remains unresolved. I respectfully urge the federal safety agency to investigate these incidents and determine whether they indicate a broader safety defect requiring corrective action. I believe repeated failures and inability to identify the cause warrants serious regulatory attention before another event occurs.

I have a 2022 RAM 1500 Longhorn Limited VIN [XXX]. It had a real problem a couple of years ago with stalling to a stop and die when making slow left hand turns. Went to the dealer twice. They claimed it was nothing but after the second visit, it no longer did it anymore. It’s done it twice in the past couple of months. This evening it did it at a three way stop sign with no turn. When it shuts off it’s in drive of course and it auto shifts to park and sets the emergency brake automatically. Then I can start the engine again but I have the press the emergency brake switch button to release it. Then the low voltage light appears on the instrument cluster and the voltage gauge stays only about a quarter of the way up above zero on the negative side. To remedy this I have to shut off the engine and sometimes open the door for a while, close it and then start the engine and all is well again. I know RAM plays dumb when I describe this to them.

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 unexpected loss of engine power while driving, creating a safety risk for the driver, passengers, and surrounding motorists. The vehicle has undergone multiple repairs for recurring MDS-related problems, but the issue has not been permanently resolved. I believe the final engine failure may be connected to the previously documented MDS failures, although the exact mechanical cause has not yet been independently confirmed. I am requesting that the federal safety agency review these recurring failures to determine whether they indicate a broader safety-related defect affecting RAM vehicles equipped with the 5.7L HEMI MDS engine.

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 coverage under the powertrain stating the vehicle had exceeded 60,000 miles. I showed them a picture of my odometer at 59,248 miles dated for the day i reported the problem and scheduled the appointment. They then informed me that standard accessory parts (belts, tensioners, etc.) are not covered under the 60,000mile warranty. They also informed me they are not covered under the 80,000 mile emissions warranty either despite their failure resulting in a complete failure of the federally mandated emissions system. The dealership indicated approximately 30-40 codes were triggered during the incident including a system code for the MGU. I requested a record of these codes and the dealership is unable/unwilling to provide.

On three occasions over the last 6 months my truck has died completely. The first time all warning lights came on and there was no speed showing but the truck kept driving. When I finally parked and restarted everything was normal. The second time all warning lights came on the cool air turned hot and then it just died while driving. I was very close to parking so no danger there. This last time I was parked in a swamp hunting and when we got back to the truck it was completely dead. I was able to jump it thankfully as we were in the middle of nowhere and it was hard to get to, not sure help would have been able to get in there. When restarted it once again had all warning lights on, said I had no gas, and wouldn't provide my speed when driving.

My 2022 Ram 1500 Big Horn V6 eTorque stumbles and cuts out during hard acceleration, this issue, when it happens has caused a dangerous performance issue to the point that I have almost been struck from behind while attempting to join the flow of traffic, the actions of either the PCM or some other engine control system cuts all motor RPM to barely an idle while traffic around me are at speeds of 40+ MPH while I am attempting to accelerate, I get a brief warning message on the display screen that flickers for less then one second (I am unable to read the warning) this is extremely dangerous. I also have been getting UCONNECT ERROR - none of these are leaving error codes in the vehicles memory.

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

Approximately 10 mins into my drive there was a burning smell in my cab, then within a few seconds there was a loud popping/exploding sound. I pulled into a parking lot within 100 feet and exited vehicle. I went to front of vehicle to see if there was smoke and after finding none I leaned back inside my truck’s cab and realized not only was the burning smell stronger but there was visible smoke lingering. At that point I saw that one of the back stationary windows was shattered. Looking closer I saw that below the window the glass was charred and the plastic trim had melted slightly. I stayed out of the vehicle and started researching the possible cause. I read several reports of issues with 5th generation Ram trucks, like mine, experienced issues like mine caused from faulty rear defrosters. After consulting with someone over the phone, I pulled the fuse for the rear defrosters to be certain there would no longer be any type of electric current flowing to the defrosters.
