NHTSA 5-Star Safety Rating
Brake noise is the most consistent theme owners of the 2024 GMC Acadia report. Across multiple complaints, owners describe persistent squealing that starts at relatively low mileage, sometimes as early as 6,000 to 7,000 miles, and continues even after dealer visits. Common service responses include rotor resurfacing, pad cleaning, and anti-squeal treatments, but owners frequently report the noise returning shortly after. Forward collision avoidance draws the second-highest complaint volume, with owners describing unexpected or nuisance activations of the automatic emergency braking system. Engine complaints round out the top three, though the narratives there are more varied. A handful of owners also mention trim and body panel fitment issues, loose or detaching exterior pieces, but those appear in a smaller cluster of reports. The brake squeal pattern, with its low-mileage onset and repeat service visits, is what stands out most consistently across this complaint set.
