Just throwing this out there. I have a friend who is currently fighting a used car dealership as we speak. Purchased a 16 GMC with low miles. The battery kept dying every few days. The used car dealer took it into GM and it has water damage. They pulled the carpet up and there is signs of flooding.

My buddy ran the car fax and it is clean. He has a friend who is in the is a cop who does grand theft ran all of the VINs from the dealer and he gets everything from Canada. From what he was telling me in Canada they don't have to report any damage? Long story short, factory warranty is now voided, truck was at the dealer for a month and has some new modules put in it....
