I have a 2019 ram rebel with 30k miles on it that is leaking somewhere on the back window. Had it towed to the dealer multiple times due to radio frequency hub getting wet and shutting down the truck. The dealership is telling me it’s going to be $1500 to replace back window but I keep hearing people say that there is an extended warranty on this leak? Can anyone help me with this before I have to spend all this money?
