I took my wife's 2002 Avalanche into the local dealer with a list of complaints, all that should be covered under waranty.
The truck sags to the left. (Suspension?) The truck wanders. (Steering, suspensions, or front end parts) The driver's door detent was broken. The rear window seal was falling out.
They called me up and said it was all because of a low tire on the front. ...oookay. They aired it up and it still sagged, the trucks till wandered, the detent was still broken, and the window gasket was still falling out.
I took it back and after a couple days they called me saying it needed a new sterring gear box. Cool I thought. They found a problem and are going to fix it. After the new gear box arrived... a day later than they said, I went to pick up the truck and noticed it still sagged to the left. (Not with me in it LOL) Oops... they forgot about that. so I came back the next day.
The truck still looked ot me like it sagged to the left, but I figured I'ld put it on a nice level piece of asphalt and take a look before I said anything. The door detent was STILL broken, but the service rep pointed that out to me before I could comment on it. Alright, I'll have to take it back yet again when that part arrives.
I drove it home. It still wanders. Thinking I might just be paranoid or maybe expecting too much out of the truck I crawled underneath. If they replaced the gear box they were very thorough. They even replaced the thin patina of rust on it and the dust on the threads of the bolts holding it on.
I wasn't sure what was wrong with the rear window trim, but my wife just showed me that it had not been fixed either.
Now supposedly between yesterday and today they adjusted the suspension and ran the truck through the car wash. When I picked the truck up today it was filthy and covered with dust from sitting in their parking lot.
Mind you, a couple weeks ago I tried to take the vehicle to the GM dealer for service only to find they no longer are allowed to provide service for Chevy trucks. I am not thrilled.
So... after all this time, as near as I can tell all that has been done is that they wasted a lot of my time on phone calls, and visits to the shop(s) and all that they did was air up a tire. MInd you, I'm not convinced of that becasue when I asked if I still needed to get that tire fixed they told me it was holding air just fine.
