“Upon starting my vehicle today the center screen did not power on.

NHTSA complaint #11491821, filed 2022-11, 6,000 miles“Throughout the year, the car had many issues, the blind spot sensors and glass sensors didn't work, and it constantly showed that the stop/start system wasn't working. Twice, the car turned off by itself at a stoplight. Since everything is controlled through the car's large monitor, including the navigation, air conditioning, and all other functions, the monitor frequently shut off and it was necessary to turn it off and on again, or wait until the next day for it to work again. The scariest incident happened during a heavy rainstorm. …”
