I have a 2018 chev silverado. Dealer was doing some unrelated warranty work on it. Removed then improperly re installed my serpentine belt and it blew up on me on the way home. Haven't had my truck in 60 days because there are none to he found anywhere on the planet. GM reached out to the company that makes the belts and they have a list of 40 other people all waiting for the same 4 rib belt. The company is located in eastern Europe and none of us have any idea when they will be built let alone shipped.
Only had the truck for 5 months. Asked the dealership if they'd buy it back and they said the best they could do is 8 grand less than I paid for it.... Sweet.
