I dropped my 2011 Aveo off at the local GM dealer this morning to have the timing belt replaced (presently at 59000km). The car has had a noticable sqeak at idle for a little while and I had them check into it at the last oil change. Got a call in the early afternoon that it wasn't actually the timing belt, but it looks to be the water pump that is noisy. They also noticed my that the right hand axle seal is leaking (both sides have now been done twice). And the real kicker is my winter tires are pretty much pooched. They suggested new tires and a 4 wheel alignment, with the likelihood of needing shims in the rear.
After purchasing the car (brand new) I thought the rear camber looked excessive. The guy who was the service manager at the time said most front wheel drives have some amount of negative camber on the rear and it didn't look unusual but to keep an eye on the tire wear. Well, that can get a little tricky when you are running both winter an summer tires, it takes a lot more use to make any issues evident. This fall when I switched over to my winter tires and rims I noticed that the summer tires were far more worn than I expected them to be. The rears were worn more than the fronts, with uneven wear through the tires. The right rear was at the wear bar, the left about 1mm off and the fronts about 2mm off. They looked scalloped or cupped. I made mention of it to the service manager since the tires themselves only have about 27000km on them despite the car having around 50k at the time. I was hoping he might do some digging or see if GM was willing to do anything. I get the impression he didn't bother, but it is impossible to know for sure as he's moved on elsewhere since. Again the winter tires are all showing a similar wear pattern to the summer tires, with the tires presently on the back having more wear than the front. I'm not much of a suspension guy, but on a car where the rear suspension is fixed with no real wear items like the front end I am a little baffled as to how a car comes from the factory in a state that would cause it to destroy tires prematurely and require shims to correct it. I am basically at the point of having to replace 2 sets of tires under 60000km. I did a little searching and found a few similar occurances on car complain sites but was wondering if anybody else on here has experienced a similar problem.
For what it's worth, the tires were rotated when changed bewteen seasons (around 12-15000km). The summers in a forward cross pattern, the winters front to back (unidirectional). I'd say over 98% of the milage is from highway use. I drive 200km round trip to work and have only gone on a couple other road trips, all on familiar roads with minimal surface issues.
