Can't really say enough negative things about this service department, they're really a tarnish on the whole dealership. I thought the sales team was great, in all areas, very polished and professional, really knew what they were doing and how to close a deal. However, my truck has a small alignment issue, which being a mechanic myself for my own old cars (vintage) I know the difference between an alignment issue, and if a steering wheel is just a bit off center and needs adjustments via tie rod ends etc..
Anyway, after taking the truck there 3 times, they just kept putting it on the computer and saying it was fine.. however, it's not, and never will be. They basically said I was wrong, and an idiot, for thinking that my truck had a crooked steering wheel. Everyone who has ever driven it comments on it. They test drove it on a road with a heavy crown.. and if you're in the right lane, the steering wheel appears straight. I'm not fixing it myself, because I leased a $40K + truck.. I should never have to lift a finger working on it and I should be 100% satisfied 100% of the time.
I'm turning this truck in early at the end of March, and I'll never buy another GMC product again. In fact, I swore off American cars 10 years ago, and I'll be swearing off them again. GET IT RIGHT GM.. they never will.
I agree with several folks on here when they say FIND ANOTHER DEALERSHIP. These guys are clueless and they probably don't have an actual mechanic who can turn a wrench anywhere in the place.
