2022 Ram 1500 Classic electrical system problems

“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…”

“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…”

“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…”

“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…”

“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.”
