NHTSA Complaint #11583349 — 2019 GMC SIERRA 1500

GMC of Vacaville California sold me a 2019 GMC Sierra that has a know back window leak issues. I was told by service worker GMC of Vacaville California sold me a 2019 GMC Sierra that has a know back window leak issues. I was told by service worker Brent Lewis/405 that is a common issue and GMC is aware of this issue that the vehicle was brought in before for this same issue prior from [XXX] but was not taken care of. I purchased this vehicle on [XXX] along with a 5k extend warranty that I was told is a bumper to bumper warranty. Come to find out it does not cover a manufacturer defected back window installation. My concern is that they are aware of these issues and water sitting on the inside of the cab due to a leak causes black mold and could cause serious illness to myself and my children.
