Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“Two days after purchasing a new 2020 Gmc Acadia I get an error on the display sd card removed along with various other error messages. Dealer talks to Gmc tech line and they advise to replace radio. Radio was replaced and errors began same day I picked it up. Dealer is replacing radio again, but unsure if this will fix the issue. The vehicle does not work as intended as when you press the nav button various error messages pop up and navigation does not work.”
NHTSA complaint #11282399, filed 2019-11, 100 miles“While in motion- blind spot sensors turn on when they should not and vice versa. Traction control has failed multiple times while driving. Predictive braking has activated improperly multiple times while driving. Cameras went out and then battery completely died. Was told fixing battery would fix vehicle. This has proven to be untrue. Vehicle is currently in for service for third time. Remains under warranty, as I have had it three months. Most recent date has been used but I've had problems since literally the first full day I have had it.”
NHTSA complaint #11343838, filed 2020-08, 3,300 miles“Brand new vehicle. Purchased on 10/30/2020. Front collision keeps flashing a red light in the top of dash that shows up in windshield. This happens with no other vehicles on the road at random times. When the vehicle needs to stop or warn you it will not. It will just let you hit a pedestrian or another car. We noticed that the same thing is happening with the rear safety cross traffic.”
NHTSA complaint #11383475, filed 2020-12, 55 miles“When it rains(or car wash) my power locks don't work. I get locked out of my car. My car reset itself in the middle of an intersection(like I turned it off and back on again). One of my gauges is always not working. The sunroof doesn't work right. Water is getting in the electrical area somehow. I've taken it to two chevrolet dealerships, but no help.”
NHTSA complaint #11646575, filed 2025-03“My infotainment screen just has lines on it. I am the second owner of this vehicle. It just stopped working on day and has not come back. I cannot use my back up camera system now either. I have read where this has been an issue with the 2020 model and a possible crimping in the wiring system. I am wondering if this is the issue here. The car has been in no accidents under my ownership.”
