My 2020 Silverado 2500HD had a leaking rear window. Long story short, and one very smelly mold and mildew problem, 3 separate failed repairs - GM has agreed to give my purchase price back. Here’s the new problem - my dealer can’t find me another truck. I don’t ‘t want to accept a check because I will have to pay sales tax on another $60,000 price tag. Anyone else have this problem? Can I buy from another dealer out of state? My dealer says there’s nothing out there.
