We have a 2022 chevy traverse bought new in 22 we have severe corrosion in front door wiring harness due to a faulty protective seal. We bought extended warranty but somehow we are told the issue is not covered by warranty. This issue goes back to at least 2010 from what I am seeing just wondering if anyone else has experienced the same thing on there late model chevys. I would like to start a class action lawsuit against chevy for this issue please tell me if you have experienced this issue on your chevy.
