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. I am not comfortable that some of the safety features have stopped working and fear that any day something else could stop working that is more important to the functioning of the car.
