My mom was driving my 2024 Ram 1500 Limited equipped with eTorque and was coming to a stop. While decelerating, the vehicle suddenly and unexpectedly accelerated forward without her intentionally pressing the accelerator pedal. She immediately applied the brakes in an attempt to stop the vehicle, but I was unable to stop it before the vehicle struck a brick building. The collision caused damage to the front of my vehicle and substantial damage to the building’s brick exterior wall. The acceleration was unexpected and occurred while she was attempting to slow/stop the vehicle. I am concerned that an electronic throttle, powertrain, eTorque/48-volt system, braking, software, or other vehicle malfunction may have contributed to the incident. The exact cause has not yet been determined. I am requesting that this incident be documented and investigated as a potential vehicle safety defect.
