The vehicle experienced total electrical failure and would not start. The car radio, door locks, and instrument panel would repeatedly light up and turn off even with the key out of the ignition. The body control module had to be replaced. Buick refused to honor the warranty on this part. As a result, I paid $575 for the repair.
