Example complaints

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

“We were driving along a 4 lane state road and the car suddenly applied the brakes hard and swerved to the right. A light blinked on the dash with a picture of the car and a red line on the right hand side. No cars were in the next lane over and there were no issues with the roadway. I was driving straight in the line and not near the left hand side of the Lane.”

NHTSA complaint #11558792, filed 2023-12

“When driving above 40 mph, I have experienced seemingly random brakes, which most likely is due to the automatic emergency braking system. I have seen it work properly when a car cuts me off in traffic, which it makes sense then. But in several instances, it's pumped the brakes when there is no obstacle or car around. It's quite scary since you might get hit from behind. One time it braked so suddenly I was jolted forward in my seat. It also has an issue with parking sensors going off also randomly going under 10 mph. All of them activate on red.”

NHTSA complaint #11642086, filed 2025-02

“Compounded Electrical Failures In addition to the battery defect, this specific vehicle has exhibited recurring electrical malfunctions, including: Total failure of the backup cameras and parking sensors. Intermittent failure of the HVAC system (Air Conditioning), critical in the Florida climate. Erratic Autonomous Braking: The vehicle has repeatedly engaged emergency braking while reversing without cause, nearly resulting in multiple collisions. …”
