2016 Jeep Renegade vehicle speed control problems

“Vehicle was returning Diagnostic code P0653 and P2138 it was taken to the dealership for servicing on 04/26/2025. Pedal position sensor was identified as the issue. Part was on national backorder for several weeks. and issue was repaired on 05/22/25. Vehicle was driven less than 100 miles and presented with the same issue on 06/26/2025 and was returned to the dealership for servicing. Service department reset the code and drove the vehicle for less than 100 miles, and indicated they could not reproduce the problem. Car was left at the dealership for a week for additional diagnostic. Car was picked up on 07/12/2025 from the dealership and on 07/15/2025 car was returned for third time to repair the issue with the same codes. A case was opened with Stellantis. At this poin car is still being repaired for the same issue. When issue occurs car goes into limp mode, and runs at 50% throttle, and has on occasion completely lost power sometimes causing some safety concerns. Vehicle was able to drive in limp mode first two times, third time required towing to the dealership”

“After starting up the vehicle several dash lights turned on including check engine and power system indicator. The accelerator pedal would not provide throttle to the engine and vehicle was in limp mode. after reading codes P2138(Throttle/Pedal Position Sensor) and P0653(Sensor Reference Voltage B Circuit High) After Dealer diagnostic it was determined that the accelerator pedal sensor was faulty and is being replaced. The issue appears common as the part is on nationwide backorder and the dealer has been waiting on the part for 4 weeks. The car is still not repaired.”

“My car has been struggling to speed up and now recently struggling to start. It did show a ADS light when trying to start and also something about a vehicle dynamic system.”

“Was sitting in a drive through and car started smoking. It stopped after I shut everything down. Then another time it overheated after driving for seven minutes had to stop. Air conditioning doesn’t work . Engine light on. Just bought from dealer with 20000 miles like a lemon. So not right.”

“While at an intersection as I was turning left across the side of oncoming traffic my vehicle completely stalled in the middle of the road the gas pedal was stuck and would not accelerate and then a code on my dash appeared Service Throttle Body, after 45 seconds the code went away and the veh was finally able to accelerate so I could move out of the middle of the oncoming traffic side of the road. I then proceeded to go straight until I could find a parking lot to pull into. Right before I was able to pull into the parking lot the Jeep did the same thing again. Would not accelerate, I put on my flashers, the same dash code came back on Service Throttle Body and after 45 seconds the Jeep went back to acting fine. I was finally able to pull into a parking lot and turn off the jeep.”

“while driving, car comes to a complete stop and stalls when accelerating. dangerous during oncoming traffic whether it's the pedestrian or the cars surrounding me. car won't move instantly upon pressing on gas pedal-- it stalls for a bit before moving.”
