Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“Vehicle purchased new mid-march 2021 and in less than 30 days the rear back-up camera stopped working intermittently. This has occurred several times and the vehicle is currently at the dealer being diagnosed.”

NHTSA complaint #11415501, filed 2021-05, 500 miles

“I got into an accident because my back up crap camera did not warn me that a car had turned behind me. Also when and backing up and a car is coming it doesn’t indicate the car is coming until it’s behind me. I’ve taken it to the dealer and they say there’s nothing wrong with it. Also there is no break when you come too close to something in front of you.”

NHTSA complaint #11463901, filed 2022-05

“We purchased the vehicle in March 2021 and within a few weeks, the rear camera started working intermittently. At one point, it displayed a black screen with a red warning triangle. The dealership ultimately replaced the camera and we haven't had the problem since.”

NHTSA complaint #11487101, filed 2022-09

“Since purchase of this vehicle in Dec 2020, the rear camera vision has been intermittent. I originally thought it to be driver problem however I am now told that there is a module that needs to be replaced and it is not available and possibly not being manufactured at the present time. As a result the entire Camera parking assist system is completely out of service with no information on when the module may be available to repair the issue. …”

NHTSA complaint #11429267, filed 2021-08

“The rear view camera was supposed to have been fixed during the safety recall in 2022, but two years later and over seven visits to dealership service repair shop, it still has not been fixed. GMC says they don't know how to fix it because they have tried everything and that because my warranty has been out one month - there is nothing they can do for me. My back up camera has not worked since the recall repair. What can I do? The car has been in the shop, who says they are contacting GMC Service Expert - but they are not communicating with me anymore. I have no car and no fix.”
