2020 Ram 1500: engine stalls while driving

Filed Oct 7, 2026 · Body, Electrical · OH

On August 11, 2026, following substantial rain, the engine unexpectedly stalled three times while the vehicle was being driven. The most serious occurrence happened at approximately 70 mph in heavy highway traffic. The engine stopped and gauges dropped to zero, while electrical accessories and infotainment remained powered. The vehicle restarted immediately but would stall again if shifted out of park. This occurred several times before staying on. No check engine light appeared at any point indicating an issue. Other stalls occurred at lower speeds. I subsequently discovered significant recurring water intrusion into the rear cab. Water visibly drips from both upper corners of the rear-window area during rain and has saturated the rear seat and reached the floor under the rear seats up to the front passenger footwell. My children’s car seats have been soaked. Moisture meter (pin based) readings confirm elevated moisture, visible mold has developed, and the interior has a strong odor. My VIN currently shows the manufacturer’s XG1 extended warranty related to CHMSL water intrusion. I am concerned that water intrusion may have affected the RF hub, wiring, connectors, or other electrical systems and may be related to the engine stalls. The cause of the stalls has not yet been confirmed as I’m waiting on the appointment.

"Factory rear window/brake light leak allowed water to flood the interior cabin, destroying the RF Hub module. This caused the vehicle to dynamically stall at 40 mph in traffic, creating a severe safety hazard."

I PCSd from Springfield, MO to Fort Bliss Texas. I bought the truck [XXX]. I make it to TX. Driving the first Saturday in TX on [XXX] it just shuts down and put me in a very scary situation. I was stuck in the middle of the high way. It does not drive. The Etorque/generator is bad and is now on order from my local Dodge dealership. It literally shut down my truck and will not start, run, nothing. It’s been in the shop for 40 days with a no ETA on the part ordered. This should definitely be a safety recall as it just stalled me on the highway. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

While coming to a stop at an intersection, vehicle engine stalled and transmission automatically slammed itself into park, with no warning, nearly causing a collision. This issue has previously been recalled for other Ram Trucks - some were not appropriately recalled and pose a major safety risk.

While driving my Ram Rebel 2020, the eTorque alternator failed, causing the vehicle to lose electrical power and forcing me to be towed. This posed a serious safety risk, including potential loss of power assist for steering and braking. The issue was addressed only by purchasing a replacement eTorque alternator part through eBay at approximately four times the normal price, because Ram is currently not producing the part. Ram Certified Dealer could not help. Stellantis / Ram customer service has been unhelpful and refused to provide a goodwill reimbursement or solution. I believe this represents a safety defect, as sudden alternator failure can cause stalling and reduce essential safety functions while driving. I am reporting this so that the federal safety agency can investigate the reliability of the eTorque alternator system and prevent future incidents.

My 2020 Ram 1500 equipped with the 5.7L HEMI eTorque system has experienced repeated failures of the charging system due to the belt starter generator (BSG) / 48-volt hybrid system. The vehicle has shut off unexpectedly while driving in traffic, resulting in sudden loss of engine power and loss of power steering assist. This created a dangerous situation where I had limited ability to control the vehicle and had to coast to the side of the road. The truck has also stalled at low speeds and intersections, requiring a restart while in traffic. When the failure occurs, warning messages related to the charging system or hybrid system may appear, and the vehicle becomes difficult to maneuver due to loss of steering assist. The underlying cause has been identified as failure of the eTorque belt starter generator (BSG) and/or associated 48-volt system components. The vehicle’s 12-volt battery is no longer properly charged, leading to repeated dead battery conditions. I am currently forced to recharge the battery daily to keep the vehicle operational. Replacement parts for this system (Mopar part number 68623194AC or superseding versions) are on national backorder with no estimated availability. My vehicle has been affected for approximately five months, leaving it unreliable and unsafe to operate. This defect creates a serious safety hazard because the vehicle can lose propulsion and steering assist without warning while in motion, increasing the risk of a crash. I am reporting this issue so that the federal safety agency can investigate potential safety defects in the eTorque hybrid system used in Ram 1500 vehicles.

The high-pressure fuel pump (HPFP) in the vehicle’s diesel fuel system failed. This component is subject to the federal safety agency Safety Recall 22V‑767 (FCA Recall Z96). The HPFP has failed more than once, including after recall replacement, and the vehicle is currently in dealer custody, making the component available for inspection upon request. The HPFP failure caused the vehicle to stall and become inoperable, resulting in an unexpected loss of motive power. This created a safety risk by leaving the vehicle disabled and unable to be safely driven. The recall itself identifies HPFP failure as a condition that can lead to engine stall without warning, increasing the risk of a crash. The repeat failure after recall repair further increased safety risk. The failure was confirmed by an authorized Ram dealership (Gene’s CDJR of Fairbanks). The dealer documented HPFP failure and fuel system contamination, performed the recall repair, and later confirmed repeat fuel system issues. Most recently, the replacement HPFP failed again during an extended test drive performed by the dealer, confirming recurrence of the defect. The vehicle has been repeatedly inspected by an authorized Ram dealership, including: Recall repair inspection and replacement of the HPFP and related fuel system components, Multiple follow-up inspections after continued symptoms, Diagnostic inspections following check-engine lights, noise, fumes, and loss of drivability. No police or insurance inspections were performed, as this was a mechanical failure handled directly by the dealer under a safety recall. There was no warning prior to the HPFP going out the first time.

I am reporting a suspected safety defect involving the Motor Generator Unit (MGU) used in the eTorque system on my Ram 1500. The vehicle experienced an MGU failure that resulted in abnormal electrical behavior, warning messages, and impaired drivability. The vehicle was inspected by an authorized Ram dealership, which confirmed the MGU has failed and requires replacement. The MGU is currently on national backorder with no estimated availability date. As a result, the vehicle is inoperable or unsafe to operate and cannot be repaired in a reasonable timeframe. Why this is a safety concern: The MGU is critical to the vehicle’s starting, charging, and powertrain functions. Failure of this component presents safety risks including loss of propulsion, potential stalling or failure to restart, electrical system instability, and vehicle immobilization in traffic or unsafe locations. The extended inability to obtain replacement MGUs significantly increases these risks. Additional information: Based on dealer communications and publicly available owner reports, similar MGU failures and extended backorders appear to affect multiple Ram 1500 eTorque vehicles, indicating this may not be an isolated incident. Dealer/manufacturer actions: The dealer confirmed the failure and ordered the replacement MGU. No repair timeline or permanent remedy has been provided. Request: I am requesting that the federal safety agency review this issue to determine whether MGU failures in Ram 1500 eTorque vehicles constitute a safety-related defect requiring investigation and potential recall action.

Entered vehicle and notice strong smell of gasoline, driving my young kids to daycare and preschool they complained of the smell and we had to lower windows. Upon dropping them off, went to mechanic who confirmed it was a fuel system issue, fixed a valve. Following few days the truck has issues starting and is stalling and jerking at lights. I return to the mechanic who advises it is the same issue and relates to the fuel pump system failing and they have ordered the part that is on a 45 day backlog. Problem persists and make my trucks unsafe to drive and I am unable to drive it. I have spoken with RAM who advised my truck model is not included in the recall AND is freshly out of warranty. This is extremely frustrating I have to spend thousands to replace this and am unable to drive my truck for approximately 2 months IF the part arrives on time.
