Example complaints

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

“While traveling down the road at approximatly 35-40 mph with my two minor children, the steering was not responding properly and the car kept attempting to veer to the right. I let off the gas to slow down since the brakes were also not seeming to respond well. Upon attempting to brake and execute a left hand turn, the car would not turn at all despite the steering wheel being as turned as far to the left as possible, the lights began flashing on the dashboard for PowerSteering ESC warning. …”

NHTSA complaint #11500332, filed 2023-01

“Purchased my 2021 Chevy Trailblazer in August 2021 with less than 100 miles. After about 500 miles the Lane assist, forward collision assistant and the automatic breaking features all stopped working. Factory reset has been set several times with no fix. The buttons on the steering wheel do not do anything when pressed. I have been told by the dealership they will need to keep my car for at least 3 days to disassemble and trouble shoot the issue, however they do not have a rental to provide me in the mean time. I am now at around 10K miles because this is my daily driving and only vehicle. …”
