2021 Chevrolet Bolt EV Driver Assist & ADAS Problems

The blind spot warning system fails to work adequately. It triggers both false negative and false positives on both sides of the vehicle. It is available for inspection upon request. Even when there are no cars within a quarter mile of me, the lights may come on, alerting me to a non-existent car in my blind spot. If the light turns on properly, it doesn't always turn off when the car leaves my blind spot, just staying on indefinitely. It fails to detect approximately 50% of cars accurately when they enter or leave my blind spot. This defect puts others at risk, increasing the possibility of a side collision when the blind spot warning system fails to adequately inform the driver of an accurate blind spot status. The vehicle was taken to a dealership with an appointment, they refused to inspect or diagnose the problem, stating that myself, the driver, should read the manual and tinker with the vehicle settings. I informed them that I had already read the manual, it stated it may take some time to calibrate and it didn't mention any user accessible settings menu, but I had over 100 miles on the new vehicle at this point and was unable to locate any user settings. The dealership still refused to inspect the vehicle. The vehicle has only been inspected by myself. Besides the false negatives and false positives of the blind spot warning system, no other error messages have occurred. This issue propped up the day I was driving the new vehicle home from the dealership after purchasing. I have attempted to personally improve the performance of the blind spot warning system using documentation found online regarding previous models of my vehicle having similar issues, I have had moderate success with using metal tape akin to duct tape on the rear of the radar sensor that powers the blind spot warning system.
