I have been a GM/Chevrolet owner my whole life. Why should I buy the most expensive vehicles on the market when obviously they’re not gonna last. I have a 2021 Denali 2500HD with 8200 miles on it. Not 82000. My AC/heater, seats all quit working. Dealer says it’s out of warranty. I might as well save a pile of money and buy Ford, Dodge or even Toyota. I had my 2017 Chevrolet 2500HD at the same dealer over a dozen times trying to get it fixed until the warranty ran out. I think I’m done with GM products. I’ll save the extra money I spend on go on vacation with it. Least I’ll expect the other vehicles to have problems. 3yrs/36,000 mile warranty. Build a truck you can stand behind. This isn’t a warranty.
