Electrical vehicle started displaying electrical malfunction issue since December 2025, at the time Audi San Juan said there was not fix available at the time.

No warning or error lights came on besides door ajar warning. The handles and locking mechanism on this q8 etron have already failed and been replaced numerous times.

When the window is half way open, and the driver is trying to close the window, the window automatically retracts and lowers the window. causing distraction for the driver and safety hazards from the road and…
