Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“On 9-May, 2026, the vehicle was driven during the morning with no warning lights or indication of component failure. Vehicle was parked on the owner's driveway at approximately 13:00. Approximately 15:40 I started the Ascent’s engine, let it idle for about 60 seconds, buckled up and scanned dashboard and rearview mirror. No warning lights or any fault indication. …”
NHTSA complaint #11736826, filed 2026-05“While pulling up to a drive thru window the vehicle shuddered and the engine shut off. I lost all power steering and had to come to a stop, shift into park, then restart the engine. No check engine lights or warnings illuminated. There were no status messages to indicate what caused it to shut off. Also the driver side mirror shakes a lot, just like all the other reports say.”
NHTSA complaint #11740740, filed 2026-05“While cruising on a 2-lane road or a freeway, the vehicle will cross over the adjacent line, either left or right. This generally happens between 50 to 75 mph. The event happens either when cruise control is on or off. Wind is not necessarily the problem. The solution requires one to take the necessary immediate steering correction. At times, the departure from the lanes may repeat. This may be a temporary correction. This may create a head-on collision if not immediately correctly manually. VERY DISTURBING!”
