2022 GMC Acadia: check engine light

Filed Jan 11, 2026 · Brakes, Electrical · CA

purchased the vehicle in good faith, unaware that the check engine light was illuminated at the time of purchase and not informed that this indicated a serious mechanical or emissions-related issue. After purchase, the dealership repaired an emissions-related problem, and the check engine light was no longer present when the vehicle was returned to me. However, within three days of having the vehicle back in my possession, I began experiencing additional issues, including electrical malfunctions and abnormal noises coming from the front wheels. These problems caused the vehicle to feel unsafe to operate and raised serious concerns about its reliability and overall safety. Due to these concerns, I returned the vehicle to the dealership immediately.

The Fuel Pump Control Module failed. It happened when the car was parked. The car would crank, but would not start. We were stranded far from where we live. It was hot and we had to be towed to a GM Dealership. This part could have failed on the hi-way with awful results. The Dealership verified the defective part. We have the old part as needed. Lots of lights flashed and went out. The Engine Light stayed on. The Gas Gauge was not reporting the correct amount of gas in the tank, but seemed to correct itself before the part failed..

I had a noise in my front driver side and the car felt like it would pull or sputter. I took it to GMC and they said the bearings are miss threaded in the transmission and it is causing problems with the sputtering and control of the car. They said this is a known problem in GMC but they do not have a recall on the car or the parts to repair it. This is a safety risk because if the transmission is slipping then I could loose control of the car and crash. It can also damage other parts to the car. No warning light or check engine light came on in the car.

My engine light came on, I took it to the service center where I purchase the vehicle. They state it is a evaporative emission canister purge pump. They state the part is on back order due to many vehicles having the same faulty part. I contacted GMC, they state the part is not available at this time. Secondly the park assist was recalled to be fixed. That part is also on back order and not available at this time.
