I now have owned my TCH for 15 months and 25,000 miles. There have only been 3 things done on warranty - the rear brake pad campaign, and something about the fronts - the pads seemed like they were "vibrating" when lightly applying the brakes, and the center console plastic was squeaking when on the freeway, and the third one was a bit of a pain to diagnose - the center vents "chattered" when at freeway speed or better, and the air conditioning fan on high.
Each one of these issues was remedied immediately, and the car was detailed inside and out when I picked it up from the dealer. I bought the dealer maintenance package with the car, so it sees the dealer every 5,000 miles. Coincidently, they are the ones that noticed the brake issue and corrected it without me saying anything.
I am absolutely impressd with this car in all respects. It seems to like cruising at 85 more than it does at 55. It rides smoother and seems to be quieter. It handles OK to well for what it is. It can pass and accelerate very effectively between 65 and 95 no problem. For an "economy" car, it is not underpowered in any way, especially considering the size of the little 4 banger gas engine, and the small amount of fuel it consumes! 500 miles on a tank of gas is not uncommon! (16 gallons)
While I feel I spent a little more than I probably should have ($36,000 out the door) I have favorably compared this car to several that are much more expensive - including a lexus I used to own. I also took advantage of the $2500 tax credit
for the Hybrid thing.
Factor in the way I am treated at the dealership and the way they make sure I am happy, such as loaner cars, detailing the car after service, keeping service appointments and all the things that the Chevy dealer never even heard of, I will never own a General Motors car/anything again! (I was a sucker when I bought my 1999 Chevy Suburban LT 1500- but that is a horror story for another forum that reads like a Monty Python Novel)
By the way, the owner of the local Chevy Store drives a Lexus! And most of his employees drive Toyotas!
