2025 Ram 2500: engine stalls while driving

Filed Oct 20, 2026 · Electrical, Engine · CT

Our 2025 Ram 2500 was purchased new in March 2026 with 41 miles. It had 17,254 miles on October 19. We completed a six week cross country trip towing a trailer without problems until September 25, 2026. September 25: The doors failed to lock automatically while driving above 35 mph. Neither key fob nor the interior electric lock switches worked, and the power windows failed. The engine and 12 inch screen remained on. Turning the truck off and restarting it did not restore these functions. As soon as we got home, we called our regular servicing dealership. They said the key fob batteries were dead. We disagreed because the interior controls and windows also failed. I independently tried the manufacturer's mobile app. Its first lock command failed; after restarting the app and retrying, the doors locked and the other functions resumed. No cause was confirmed. October 17: While slowing for a stop sign, the engine suddenly shut off. The display instructed the driver to shift into Park to restart. A vehicle was behind us, but the hazard warning lights and power windows would not work, so we could not warn its driver. The truck restarted after shifting into Park, pressing the brake and pushing Start. October 19, about 6:40 AM: A different driver was coasting toward a traffic light at approximately 5 mph or less, without hard braking, when the engine shut off again. The display said "Shift to Park to Start." The driver shifted into Park and pressed Start to restart. Both shutdowns happened during deceleration without advance warning. The Ram app recorded the trips but showed no active driving alerts. Unexpected stalling in traffic, especially with failed hazard lights, poses a collision risk. I called Ram Customer Care as soon as they opened on October 19. A dealership inspection is scheduled for October 21. The cause remains unknown, no repair has been completed, and the truck is available for inspection.

Subject: URGENT – RAM 2500 Shutdown / Near Accident / Case #XXX Hey [XXX], The truck shut down AGAIN tonight, XXX, and I nearly got into an accident. I recorded another video and called RAM to open Case #XXX. I plan to return it tomorrow morning; please coordinate safe transport. This has been ongoing for approximately a year. My 2025 RAM 2500 intermittently shuts down while driving: the engine stops, the instrument cluster goes black, and the truck goes into Neutral, losing propulsion. Previous incidents occurred at approximately 20–80 mph, with the first within 800 miles of ownership. The instrument cluster was replaced around 16,000 miles following Stellantis engineering guidance. That did not fix it. Another shutdown occurred around 18,000 miles while transporting employees to [XXX], as documented in my August 3 summary. The dealership previously discussed a new STAR case and escalation to a Stellantis field specialist (“Top Gun”). Please confirm those actions, provide the STAR case number, and link the repair history and videos to RAM Case #XXX. I need immediate engineering escalation, a documented diagnostic plan, and a permanent, verified repair—not more trial-and-error parts replacement. Since previous failures reportedly left no fault codes, please consider long-term diagnostic logging to capture the event. I am willing to leave the truck for several weeks. My priority remains fixing it, but if Stellantis cannot resolve this, I expect a formal review of buyback or other resolution options. This is a serious, recurring safety issue that nearly caused an accident tonight. RAM’s response will directly affect our company’s future business with the brand.

Our 2025 Ram Rebel stalled on a 55-mph curve on a busy freeway. Fearful, I deliberately drifted the vehicle to the right side of the road looking for an emergency lane. The truck regained momentum and I drove it another 10 miles. Coming to a stop, I heard mechanical griding and felt the truck shudder. I drove it home. My husband took the truck, and the same griding and shuddering happened to him twice over a 15-minute period while driving on surface streets less than 20 mph. The truck did not stall on him. -We have been told by the dealership that the transfer case failed. The dealership is working to fix it. -My safety and those riding in my vehicle were put at significant risk due to the stall on the freeway and a transfer case failure. -The problem was confirmed by an official Ram dealer where we purchased the vehicle. -The transfer case failure has been inspected but the reason for the stalling has not been identified. -A warning light "Service 4WD" turned on each time we heard the grinding sound but then turned off. We bought the vehicle new, have owned it 11 months and it has $15,000 miles. All services have been conducted according to the maintenance schedule.

Subject: Safety Concern – Vehicle Shuts Down While Driving / Request for Replacement Despite multiple warranty repair attempts, my 2025 Ram 2500 continues to experience unresolved electrical failures. In addition to the previously documented issues, the vehicle shuts down while driving, forcing me to immediately pull over, place the vehicle in park, and restart the engine in order to continue driving. This condition has occurred unexpectedly and without warning. Losing power while the vehicle is in motion presents a serious safety risk, especially during highway or interstate driving. Given that I rely on this truck for work and frequently travel long distances between New Jersey and Texas, this behavior makes the vehicle unsafe and unreliable for its intended use. The truck has already undergone repeated diagnostics, module replacements, software updates, wiring repairs, and battery replacement at authorized Ram dealerships. Despite these efforts, the issue persists. At this point, I have lost confidence in the safety and reliability of this vehicle and do not feel comfortable continuing to drive or own it. I have acted in good faith and allowed multiple opportunities to repair the vehicle. The ongoing shutdowns while driving demonstrate that the defect has not been corrected within a reasonable number of attempts. Requested Resolution: • Immediate escalation of this case due to a safety-related defect • Replacement of the vehicle or trade-assist into another Ram truck • Reimbursement for loss-of-use expenses incurred due to repeated service visits I am requesting a definitive resolution rather than additional repair attempts.
