2020 Ram 1500 acceleration problems

Filed Oct 26, 2026 · Acceleration · ME

I am reporting a serious safety concern involving our 2020 Ram 1500 Rebel. The vehicle has experienced repeated incidents of unintended acceleration, where it accelerates without the driver pressing the accelerator pedal. This problem has occurred on multiple occasions and presents a significant risk to the driver, passengers, and other motorists. The vehicle previously displayed diagnostic trouble code P2138, which relates to the accelerator pedal position sensor circuits. We are concerned that this may indicate a malfunction involving the electronic throttle control or accelerator pedal system, although the exact cause has not been confirmed. The issue has now occurred again, raising serious concerns about the vehicle’s safety and the potential for an accident. We believe this dangerous and recurring condition warrants investigation by the federal safety agency. We are requesting that this complaint be documented and investigated to determine whether a safety-related defect exists.

The truck has an issue with 3rd gear. It wants to jolt forward and if it doesn’t catch speed it goes into “limp” mode. It’s a safety feature where it goes as fast as 2nd gear needing service to Electronic throttle body, stop/start system, and electronic stability control.

While I was driving warning lights came up on the dash. Traction control, parking brake warning, red voltage. When I exited the freeway, and used the brakes to slow down , the truck was accelerating at the same time . I let go of all the pedals, and the acceleration continued with no feet on pedals . When I got to work, I put it in park . Took it out of park, and the truck started accelerating again on its own at a fast rate. Put it in park, put it in reverse, and the truck started accelerating fast again, in reverse, until I slammed on the brakes to stop the acceleration and put it into park . This is the second time. First time was few months ago, same issue. Dealer looked at it, couldn’t duplicate it, cleared the codes and said if it happens again they’ll have to call an engineer from Chrysler. Contacted dealer today , said nothing about an engineer and that they can’t look at it until next week.

I bought my 2020 Ram on 6/7/2021, driving it home that night the throttle body control sensor and the steering stabilizer sensor failed and came across my dashboard along with a check engine light, the truck started quickly acceleratingon its own, I had zero response from the gas pedal I could only use the brake. The next day it went back to the dealership to be fixed. They replaced the sensor in the gas pedal. I had to wait a few days to get it fixed. On 6/23 this problem happened again, the truck started rapidly accelerating on its own. The dealership towed it from my house to an authorized Ram dealer. I had to wait 2 weeks to get it back. I got it on 7/7. The dealership said that they did computer work to the truck but found no other issues, the sensor in the gas pedal was fine. Driving home from work last night 7/9 the dashboard lit up again and the truck started accelerating on its own for the 3rd time. I am now afraid to drive it.
