Their wikipedia page says they announced “a partnership with RepairPal, a network of certified auto repair shops and dealerships across the US, to give owners access to 4000 service points from day one”. I don’t know if a “service point” is the same as a mechanic shop though.
RepairPal is just a rent seeking middleman like Angi's list. I don't see what that partnership will provide, certainly not shops that are trained to repair the truck.
