What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
When backing into my driveway the brakes failed. I was nosing the car across the street towards the neighbors driveway so I could put the car in reverse and back it into the driveway.
On September 26th, 2026 I got a random notification about needing to get my rear left turn signal checked out as it still functions but blinks rapidly. Today, September 28th, 2026, I visited my local dealership for the issue and was informed that they had received a bulletin regarding the concern but that instead of…
Well, let’s try this again. The first try disappeared. The rear hatch seal on the vehicle has identical spots on both sides of the hatch that are mashed flat. I think this is being caused by the flat spots on the hatch itself. The vehicle is a total body and engine redesign.
The car suddenly reduced power, air conditioning stopped, assisted power brakes stopped working, gauge cluster full of flashing warnings. Pulled to the right shoulder, stopped with difficulty. Had to pump and stand on brakes to get stopped. Shut off engine, then restated and everything stated working again.
The contact became aware that the top of the steering wheel was cracked and had popped out of place. The contact stated that while driving, the failure caused a cut on the hand. The vehicle was taken to the dealer, where the failure was confirmed. The contact was informed that the steering wheel needed to be replaced.
2024 GMC Acadia grounded at dealership for 3+ weeks due to unavailable driver seat belt buckle (Part 26522477), rendering a brand-new vehicle legally un-driveable due to primary restraint part constraints. The buckle will not latch, causing the seat belt to be rendered inoperable.
At low speeds the brakes squeal horrendously. We have taken the vehicle to the dealer multiple times and each time they state that the brakes are fine. A vehicle with this low of miles should not have squealing brakes since new.
The vehicle had yet to be diagnosed or repaired for the failure. The dealer nor the manufacturer had yet to be notified of the failure. The failure mileage was approximately 17,500.
