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.

Sudden loss of power by model year
What owners say
Power steering has an intermittent failure and have lost power steering multiple times on the highway. Warning lights come on a indicate steering issue. Have noticed this has been reported as an eps issue with the ram 1500's. This has been reproduced by an independent service center and they thought it might be a loose connection with water getting in. They tried to fix this but still getting the issue even when there is no rain. This just started once I passed the 36,000 mile mark and no longer under warranty This is a serious issue as power steering goes out unexpectedly
Truck for about the 6th time in 2 weeks, shut its self off while driving and slams into park. This has happened before and had to be towed to dodge because it wouldn’t restart. I told them what happened and they informed me it was low on fuel, that’s why it did it. But I was doing 60mph on a interstate and lost all power
Dodge Ram Engine light and battery light turn on. I take it to a mechanic close to my house. Service manager connects the truck to the computer and vehicle shows error in alternator which. Dodge specific parts and he advises me to take the truck straight to dodge and not drive it anymore that the battery voltage is dropping and not charging. He sends me email breakdown of all error codes and tells me to give it to dodge. I drop off at dodge and provide all information to advisor including error codes. I tell them everything that happened and what the manager said about the battery voltage. They claim all information I provided wont all fit on the ticket so erases it and put basic information regarding voltage error. I offered to show him the pics and the report that was provided to me by other mechanic but he stated that they will have to do their own diagnostics anyway. Says that my truck has a bunch of software recalls that may clear the problem. I get a call they did a software update that cleared and fixed the problem and it wasn't the MGU. Vehicle was fixed and i could pick up. I pick up truck and the warning lights were cleared. Took it home no more driving. My 17 year old drives truck next day for school event, on his way to school event both lights turn back on. I tell him to come straight home we switch cars and i take directly to dodge. As i'm driving I'm paying attention to the voltage on battery, within a 10 mile drive to drop truck off at dodge the voltage goes from 12.? down to 10.9V. at 10.5 V the vehicles computers will lose power which can cause the power steering to go stiff, transmission to lock up or engine to stall abruptly mid drive. If this would have happened while my son was driving on hwy loop 410 in San Antonio (a major and very busy road) it could have been a disaster causing a wreck, potential loss of control or worse potentially ending in death or serious injury in a truck that was released the day prior as being fixed.
The contact owns a 2022 Ram 1500. The contact stated that while driving approximately 40 MPH, the vehicle lost power and coasted to a stop along the curb, stalled, and the transmission independently shifted to park(P). The vehicle failed to restart, and the Police arrived on the scene to assist with traffic control. The vehicle was towed to the local dealer, who replaced the high-pressure fuel pump as part of the repair under the federal safety agency Campaign Number: 23V263000 (FUEL SYSTEM, DIESEL). However, the repair failed to fix the vehicle. The vehicle was towed to a second dealer, and it was determined that during the failure with the high-pressure fuel pump, the valves in the engine were damaged. The contact was informed that the engine needed to be replaced. The vehicle was not yet repaired. The manufacturer was notified of the failure. The failure mileage was 139,000.
Failed Component: The Motor-Generator Unit (MGU) of the 48V eTorque mild-hybrid system, which acts as the vehicle's alternator and starter generator.System Affected: The electrical, charging, and powertrain systems. Sudden Engine Stalling: The vehicle suffered a complete loss of motive power without warning while traveling at highway speeds.Loss of Critical Controls: When the engine died, the truck lost power steering assist and power brake assist, making a 5,000-pound vehicle incredibly difficult to steer or stop. Status:vehicle at the dealership, failure was confirmed by John Hiester Chrysler Dodge Jeep Ram of Lillington. The vehicle has been inspected by the dealership technicians. Dashboard Warning Lights: The Battery/Charging System light (red battery icon) and the Malfunction Indicator Lamp (Check Engine Light) illuminated on the instrument cluster. Notifications on dashboard of no power steering and ABS.
Purchased my used RAM October 2024. On 5 occasions the engine stalled while driving. Lost all power and rolled to a stop when the parking brake engaged. Most recent incident was May 17, 2026. I went to my dealer with this complaint May 14th, there were no codes and I was told truck was operating as designed. I am unable to duplicate the event - but it happens when I slow down and then speed up - Stop sign, parking lot etc. Potentially I could have run over someone or crashed or someone could have struck me. I received no warning before the stall. The check engine light did not come on. While stalled the following messages appeared on my dashboard 1. press brake and push button to start; 2. Shifter autocorrect active; 3. Park brake auto engaged press brake + push switch to release. The truck restarted but battery light remained on and the lightning bolt red light stayed on.
I am reporting a serious and ongoing safety issue with my Ram 1500. The vehicle has experienced multiple incidents of complete power loss while driving, including at highway speeds. During these events, the vehicle abruptly shuts down without warning. The dashboard lights illuminate (including the battery and check engine lights), followed by total electrical failure. The engine turns off, the radio and displays go dark, and I lose power steering and braking assist, then the emergency brake engages, making the vehicle extremely difficult to control. These incidents have occurred more than once and are unpredictable. In at least one instance, I was forced to pull over on the highway after the vehicle lost all power while in motion. The loss of steering and braking assistance created a dangerous situation, especially as I have had my children in the vehicle. After one incident, the vehicle was jump-started and the battery was replaced; however, the issue recurred. A mechanic previously reported that no diagnostic codes were found and no problem could be identified, despite the severity of the failure. The vehicle is currently at the dealership for further evaluation. This issue appears consistent with other reports of Ram 1500 vehicles experiencing sudden loss of motive power and electrical failure. The intermittent nature of the defect and lack of diagnostic codes make it difficult to detect, increasing the safety risk. I do not feel safe operating this vehicle, as it can shut down without warning while driving. I am requesting further investigation into this issue due to the significant risk of crash or injury.
I experienced a sudden loss of power steering at 75 miles per hour on the freeway. This created an immediate safety hazard. I am requesting manufacturer goodwill repair assistance and for the dealer to open a safety case
I own a 2022 Ram 1500 with a 5.7-liter V8 equipped with the eTorque (mild hybrid) system. On October 24, 2025, at approximately 1:30 p.m., I was driving southbound on I-25 when the battery warning light illuminated, followed by several other warning indicators on the dashboard. Shortly thereafter, the dashboard went completely dark, and I suddenly lost power steering. At that point, the truck was moving only on momentum. While I was able to brake and activate my emergency hazard lights, the vehicle eventually came to a stop on its own in a lane in the middle of the highway. Fortunately, traffic was moving slowly due to it being a Friday afternoon. This was a frightening and dangerous experience, particularly due to the sudden loss of power steering. I could have collided with another vehicle, or another vehicle could have struck me. I feared for my safety during this incident. The truck was eventually towed to a nearby Ram dealership, where the battery was replaced. I was informed that the battery had failed and, as a result, caused the entire vehicle to shut down. Approximately two months later, I began hearing a ticking noise from the engine—commonly referred to as the “Chrysler tick.” I had to return the vehicle to the dealership for a second time. Ram ultimately replaced the engine; however, I was required to pay approximately $3,000 out of pocket for the repair. Given these serious and costly issues, I am no longer confident in the reliability of the brand.
The contact owns a 2022 Ram 1500. The contact stated that while driving 70 MPH on the highway, the power steering warning light illuminated, and the vehicle lost power steering functionality. The contact pulled over to the right side of the road and waited for tow truck assistance. A dealer was contacted. The vehicle was towed to the dealer, where it was diagnosed, and determined that the power steering module needed to be replaced. The manufacturer was not notified of the failure. The approximate failure mileage was 50,000.
On Friday, January 9, 2026, my Ram 1500 lost all power and would not re-start for approximately 15 minutes on Folsom-Auburn Road, in Folsom, a 50 mph speed limit road. After appox. During that time I blocked traffic in the left hand lane, unable to restart the truck. 15 minutes later (with a tow on the way) it started and has been running without issue since. I brought my truck to the local dealer, Folsom Dodge Chrysler Jeep Ram, on Wednesday, January 14. They tracked the problem to a failing electrical module below the rear window. It is corroding because the rear window started leaking. The total repair estimate was approx. $5000. My truck is a 2022, I bought it new in January, 2022 and it has 45,000 miles. In addition to the manufacturer's warranty I purchased Mopar's Max Care plan, with coverage for 85,000 miles and 8 years. In spite of this, Mopar denied the warranty claim. However, after speaking with the dealer's service manager and asking for good-will coverage, Mopar agreed to pay for 80% of the repair cost. The repair is now pending receipt of parts, which the dealer anticipates may take up to three weeks to collect. I am still driving the truck, as I rely on it for transportation.
