Seat Belts
06/23/2026
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. The problem was reproduced by the dealership, and the replacement part is backordered.

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.

My complaint does not involve an accident. The brakes on the 2024 Acadia Elevation are squealing very loudly, and have been doing so for the past six months or so. I have approximately 18,000 miles on it. I took my vehicle to the dealership twice for this issue, and I was told this time that the brakes are still good (still 8mm of pads) - even though it was showing 22% brake pad. They told me about the malfunctioning sensor and they fixed that, but the squealing is still there. I was told that it was the metal composition of the brake pads that is making that noise, and GM does not cover brakes past 7,500 miles (this 7,500 warranty is pointless because who would need brakes replaced in that short time frame, anyway?). That means I would have to pay out of pocket for the brakes! There is clearly something wrong with the structure of the brakes and I see on the Acadia forum that this is a common complaint.
