2023 Jeep Gladiator: check engine light

Filed Jul 14, 2025 · Engine, Transmission · NC

The vehicle was being driven on a 4 mile stretch of interstate 26 averaging between 65 and 70 MPH. On the steepest section of the grade the vehicle downshifted into 7th gear and began to lose power. It showed a check engine light and other codes which are attached. I was able to safely pull over to the shoulder but the vehicle lacked power and pulling over and maneuvering on a steep grade was precarious. I received an alert from the Jeep mobile app on my phone shortly after instructing me to take my car to schedule an appointment now. I was able to use a scanner application JScan to clear the code and was able to return home without further incident. I investigated the code that was provided by JScan “P00AF” and discovered that numerous owners had experienced the same situation across all lines of vehicles that use the Gen 3 Ecodiesel. I counted 37 separate reports while using Google in 15 minutes of searching. This is a serious safety issue as I was traveling at interstate speeds uphill and went from 65-70 mph down to a slow rate of travel in a matter of seconds and to my knowledge no brake lights illuminated as cars were changing lanes behind me rapidly due to my sudden decrease in speed. It appears likely to be a programming or electrical malfunction with the turbo wastegate actuator and corresponding sensors that is not indicative of an actual turbo or wastegate actuator failure. If the computer algorithm is using barometric pressure for pairing boost set point and actual boost based on residual data that is not updated in real time, when ascending steep grades and gaining hundreds of feet in elevation over a short duration, air pressure values could potentially be skewed resulting in a mismatch in actual versus expected turbo boost output. My vehicle had only been running for 12-14 minutes as I live at the base of a large mountain and left home and began my ascent within 10 minutes. Therefore my oil and engine temperature were not elevated.

My check engine light came on and I was told it set a code for a flash update . Dealership did the update and told me if the light came back on it was the fuel pump . Light came back on and I took it back immediately to dealership . They said perfectly safe to drive , it’s the fuel pump . My jeep truck only has 22,000 miles on it . Three days later I was driving home and the vehicle engine light was turned off by the dealership a second time and the fuel pump went out while I was driving with no light warning or nothing and my truck came to a sudden stop in the midst of me driving . Traffic was behind me and beside me . I was nearly missed . Jeep evidently has known of this same massively reported issues with previous models from 2020-2022 models. This is a huge issue driving and the vehicle just came to a sudden stop Locked down the shifter . Could not move the shifter without assistance to even put the truck in neutral to move it out out of the middle of traffic. Luckily the towing company knew how take the key and strap it into neural to move it . I pray Jeep Manufacturers are held accountable for not having this already become a safety recall . I seen many reports of this exact issue for their models since 2020 on Jeep Group Facebook community complaints for the Jeep Gladiator trucks after I experienced this possible death threat . Woe to the consumer whose lives could be at stake.

The contact owns a 2023 Jeep Gladiator. The contact stated that the vehicle was repaired under an unknown recall by the previous owner; however, the check engine warning light illuminated. The contact examined the vehicle and became aware of some loosened fasteners. The vehicle was taken to a local dealer where it was diagnosed that there were defective parts associated with the federal safety agency Campaign Number: 23V116000 (Power Train). The vehicle was not repaired due to parts being on backorder. The contact stated the fuel casket, canister purge valve, and fender liner had previously been replaced. The contact was not provided documentation of any repairs that were performed. The manufacturer was not made aware of the failure. The failure mileage was approximately 300.

Was driving and my vehicle came up and said I had an issue with the electrical power steering assist system and was going to shut off. I was waiting at a red light the vehicle put itself in park and shut down. I restarted the vehicle and it would not move out of park or any of the windows or radio controls would function. I upon restarting four more times was able to get it back into drive and return home. The steering functioned fine but the radio, back up camera, aux power port, and windows still do not work. Once I returned home this seems to be a reoccuring problem on the Gladiator and Jeep Wrangler platforms. Seems these vehicle throw either one of two codes which I am not sure which mine is but considering the light is out for check engine I am going to say I have the P0563 error and not the P0562 which from what I am reading leaves the light on in most instances. My vehicle has 1803 miles on it and was purchased the first week of April 2023.
