Please tell us how you voided your bumper to bumper warranty.


Take it to the dealer and have them look at it since it’s still under warranty.


Initializing the power window won’t void the warranty, the instructions are in the owners manual.

Good advice above to let the dealership handle anything beyond the manual’s reset procedure. If that doesn’t do the trick, could be a wire has shorted out.
