I live in Texas, and purchased a used vehicle a few months back. Mileage was well below the limit to qualify for the bumper to bumper warranty. Electronic issues started, took it into the Buick dealership, and they've stated that there was an aftermarket windshield added, and water had leaked into areas that was causing the problems. Buick dealership is claiming this voids the warranty, however I had no idea about the windshield because that was done before I purchased the car. To add to this, I purchased the vehicle at a separate dealership, not from Buick. First of all, do I have any way to get them to honor the warranty, and if so, who should honor it? The Buick Dealership, or the one that sold me the used vehicle?
