2022 GMC Acadia

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.

The contact owns a 2022 GMC Acadia. The contact stated that while depressing the brake pedal to stop, smoke began to fill the cabin of the vehicle. The transmission was switched to the park position and the contact exited the vehicle and discovered flames and smoke coming from the front brake rotors. Moments later a clicking noise was heard and the unoccupied vehicle rolled down an incline and crashed into a tree and came to a stop. A police report was taken at the scene. The vehicle was towed to the local dealer. The cause of the failure was not determined. The manufacturer was notified of the failure but no assistance was offered. The failure mileage was 15,000.

The contact owns a 2022 GMC Acadia. The contact stated that while driving at night at an undisclosed speed, the instrument cluster light inadvertently turned on and off. Additionally, the speedometer was inoperable. The turn signal warning light was illuminated, and the headlights inadvertently illuminated on and off while driving. The vehicle was taken to the dealer on three separate occasions; however, the dealer was unable to duplicate the failure. The dealer replaced an unknown module, but the failure recurred. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was unknown.

This is about my brand new Acadia. One of the seatbelt locks of the second row is missing. I did report the issue to the GMC local dealer and they’re to replace the missing lock, however, I was expecting to get GMC to take immediate action as this is a major safety concern. I have received no communication back from them yet. I’ve got the vehicle in Tijuana Mexico and typically drive it in both California USA and Baja California Mexico.

Driver side blind spot monitor fails to detect vehicles. I first became aware of the problem as I was entering a freeway and nearly caused an accident. I scheduled service at my GMC dealership but had to wait two weeks for an appointment. The system stared working again just before the appointment and the dealer service department could not find a problem. My neighbor's 2021 GMC Acadia has the same issue. Does somebody have to die to correct a safety defect?

Several times the Automatic Emergency Braking (AEB) was activated unnecessarily. Twice were at a 4-way stop. I was turning left with a stationary car (#1) across the intersection waiting to proceed next. As I got part of the way through the turn, the AEB reacked to the car (#1) and engaged. Slowing my car and almost brought it to a full stop in the middle of the intersection. I now drive the car with AEB disabled.

The cruise control does not down-shift the vehicle early enough. it does not react for the first 6mph over set point and then when it downshifts it only downshifts one gear. The vehicle exceeded 10mph over set point on a 6% grade and brakes had to be engaged because manual limit did not perform as intended at the moment. This might have been ok in the 90s but all other cars I had handled this much better in last 15 years. The lane keep assist attempts to drive the car into oncoming traffic when there are road patches present in the lane.
