2024 Ram 1500: start-stop system problems

Filed Oct 27, 2026 · Engine · FL

When driving at slow speed with the auto stop/start turned off the engine will shut off and have to reset to park before it can restart. This doesn’t happen often and the dealership says it can’t duplicate it and there is no malfunction code in the data storage.My fear is this could happen in traffic and cause an accident.

Vehicle: 2024 Ram 1500 Big Horn – 3.6L V6 eTorque Approximate mileage: 41,400 miles I am submitting this complaint regarding multiple incidents involving unexpected engine RPM increases, abnormal acceleration, and delayed throttle response following activation of the Auto Start/Stop system. On two separate occasions, while accelerating, the engine RPMs unexpectedly increased to approximately 3,000–4,000 without a corresponding increase in vehicle speed. The truck felt as though the transmission was temporarily disengaged or in neutral. I had to release the accelerator to allow the RPMs to return to normal. On October 11, 2026, I experienced another concerning incident while stopped at a stop sign preparing to make a right turn. The Auto Start/Stop system had shut off the engine while I was holding the brake. When I released the brake pedal, the engine restarted immediately. However, when I lightly pressed and held the accelerator, the vehicle did not move, and the engine RPMs did not increase. It felt as though the vehicle was being held in place despite my foot being off the brake. After approximately 2–3 seconds, the vehicle began moving normally without me releasing or pressing the accelerator again. No dashboard warning lights or error messages appeared during these incidents. Approximately three days before the latest incident, I brought the vehicle to an authorized Ram dealership and reported the concerns. The dealership performed diagnostic checks and a road test but informed me that no diagnostic trouble codes were found and the problem could not be reproduced. I was advised that my concerns were documented in their records. Despite the dealership inspection, the vehicle experienced another malfunction. I am concerned that these intermittent issues could result in a collision, particularly when entering intersections, merging into traffic, or accelerating from a stop. I am requesting that the federal safety agency review these incidents and investigate whether simila

My vehicle is equipped with an automatic engine stop/start feature that shuts off the engine when the vehicle is stopped, as well as an eTorque system intended to assist with initial acceleration. While stopped at an intersection with a slight downhill grade (foot fully depressing the brake pedal), the auto stop/start feature engaged and the engine shut off. When I released the brake to make a right turn, neither the engine nor the eTorque system reengaged. As a result, the vehicle rolled forward under its own momentum into oncoming traffic. I immediately reapplied the brake to stop the vehicle. At that point, the vehicle unexpectedly shifted itself into Park, even though the engine never restarted. I then pressed the ignition button to turn the vehicle off and back on in order to restart the engine. After restarting, I was able to shift into Drive and move into the traffic lane just in time to avoid a collision. A crash was avoided only because oncoming vehicles were able to change lanes to avoid striking my vehicle. At the time of the incident, the vehicle had more than one-third of a tank of fuel, fewer than 33,000 miles, and has been serviced exclusively at the dealership. This incident occurred at the intersection of Riverbend Road and Park Road in Charlotte, North Carolina.

The reported vehicle has experienced repeated, critical stalling events immediately following the activation of the engine Start/Stop feature. The engine shuts down normally when the vehicle comes to a stop (e.g., at a traffic light or stop sign) but fails to automatically restart when the brake pedal is released or the accelerator is pressed. This leaves the vehicle immobilized in traffic, creating a significant safety hazard. Incident Details The stalling behavior has occurred multiple times under normal operating conditions. The issue is intermittent but frequent enough to cause concern for vehicle safety.

Truck has auto start/stop for fuel efficiency. It automatically engages on startup. Truck is prone to sudden unexpected acceleration when it is engaged. Has almost caused 3 wrecks with my truck. Dealership says they know about the problem and that I should just turn it off everytime I get in the truck. This will kill somebody some day. I forgot to turn it off today and it almost caused me to rear-end another vehicle while at a stoplight.
