We have had basically two significant problems with this car. During the second year of ownership, with less than 20,000 miles the car developed an oil leak on the intake manifold. It was still under warranty so we took it in to the dealer to get it fixed. It took two attempts by the dealer to get it right. Then the following year it started leaking again. This time, we had to take it back three additional times before the dealer got it resolved. Thankfully it has not leaked since.
The second, and most troubling problem, has to do with the brakes. Last summer, we had to replace the front brake pads and rotors having driven less than 40,000 miles on the original equipment. Then, again this year, at about 45,000 miles we had to replace the front, pads and rotors again as well as a significant pads and something else (I don't recall) on the rear brakes. This is outrageous. Why is it that GM could not have done a better job on the brakes for this car. To make matters worse, we had to take the car back to the dealer after driving it for one day on the most recent brake repair because they would not stop the car. This could have been tragic. We have two big problems here. 1) poor design on behalf of GM and 2) poor quality repair work at the dealer.
My family is an exact match in terms of target market for Chevy products. Married with 2 kids. GM really missed the mark on this one. As a result I will not buy another GM product. This is true even though I have racked up $3,000 worth of GM bonus dollars on my GM Credit Card. I will buy a new car in the next 30 days and it will be from a Japanese manufacturer. I have given up on our domestic auto-makers.
You live and learn my friend. Welcome to Toyota! :)
