I went to a BBB arbitration Yesterday for my 2015i Escalade ESV. GM agreed to purchase the truck back before the arbitration, but wanted to charge me use mileage for 4800 miles. The truck has 6000 miles and it all started around 700-800 miles.
FYI...MAKE SURE WHEN YOUR SERVICE WRITER, WRITES YOUR REPAIR ORDER IT STATES "ROOF BUFFETING". We had several tickets wrote up with roof buffeting, but the last one was written up with "a drone in the car and it still exists". GM said now that is a whole different problem now... I told them its the same damn thing. They are trying to play on semantics....
The other thing that came up from GM...they stated in our warranty book that came with these vehicles it states that they are NOT responsible for noises in the truck. I will look for it and post the info for everyone. I will have a decision in 3 business days.
