Vehicle was towed to local GM dealer and assessed. Have been told that transmission needs completely rebuilt, but no description of actual issue.

While deiving in three lanes of traffic in rainy weather. The vehicle began to buck as though the engine was cutting on and off. No warming lights or abnormal noises preceded the event. The vehicle lost traction several times, but recovered. As quickly as it happened it stopped and normal driving resumed. It occurred 2 more times after approximately 1 mile of travel. I was able to limp the vehicle home, but once I shut it off it would not start again. I had it towed to the dealership and the service consultant informed me that it was the Fuel Pump Control Module that had failed and it was covered under warranty.

There are currently approximately 22,000 miles on this vehicle. On approximately December 22, 2023, the car was operating normally, and has been since purchased with 3 miles on it, the car was being parked into a flat parking spot at a local store, when the car was stopped completely, the engine/start button was pushed, which normally put the car into park and shut the car down, this time, the car shut down but NEVER went into Park and started to drift forward approximately 2 feet before the driver was aware that the car was moving. Luckily there was enough room left when the car was parked if not it would have hit another car or someone else. The passenger door was opened upon shut down and the passenger was getting out and that was the only way the passengers knew the car was still moving. The car or incident has not been reported to the dealer as of now but will be in the near future. There were no warning lamps or messages however the brakes were hit immediately upon recognition and the D light was still illuminated. This issue has not been recreated nor has it happened before.

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.

Secondly the park assist was recalled to be fixed. That part is also on back order and not available at this time.

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.
