Very bad shimmy and shake when braking, also when trying to spped up from a dead stop or otherwise car pulls back, or stumbles. At about 45000 miles a valve broke into three pieces. Had heads replaced. Brakes and stumbling is reoccuring brakes since I bought the car new in 99 and stumble since early 2004. Speakers located in the back seat panels also keep blowing out.

Car will not brake or stop smoothly. Condition is warped rotors. Selected a well known popular parts shop for replacement rotor. Replacement rotor is diamond cut w/O holes. Bigger cooling vains with a set of porcelin pads. Unknown at this time if this corrects the warping problem.

Rotors first became warped at around 20,000. Rotors continue to become warped every 5-10,000. GM/Chevrolet refuse to admit or fix this defect despite numerous complaints from many drivers.

Car only has 40000 miles on it and whenever I would brake or come up to a stop light, the wheels would shimmy and the steering wheel would vibrate. I was afraid it would not stop and would cause an accident. I took it to the Chevrolet dealer in waldorf md. The mechanic said he could find nothing wrong with it and could not make it do it. That was 2 months ago and it still does it all the time. Sounds like all these other similar complaints for this vehicle.. defective warped rotors. This is very dangerous and I cannot get a dealership to fix it.

Both front rotors have been turned twice to releive wearout. Rotors will have to be replaced again, and will not be covered under warranty by manufacturer. Defective rotors do not allow consumer to stop vehicle appropriately which could cause an automobile accident.

Dealer has refaced front brake rotors twice once under warranty and once for $100 I believe the rotors to be defective due to oem quality or heat treat specifications and engineering standards, there are aftermarket rotors available that do not warp with the severity and frequency of the oem parts.
