Clunking noise in front end especially when you are in a turn. Also could feel a "thump" through the steering wheel at same time. We are stationed in germany in the air force. Took it to the opel dealer (chevy equiv. In germany) and they diagnosed it as the intermediate shaft needing to be replaced. After $300 and a long time waiting for the part, it was replaced and hasn't given us a problem since. Also have had major problem with this car "eating" brakes and rotors. Reminds me exactly of my Buick regal I had with the same brake issues. After I sold the regal, I was sent info on a class action suit against GMC for the same brake issues. Both are great cars but brakes stink.
Vehicle braking system malfunction. Refer to odi # 10134740. System failure resulted in loss of vehicle control resulting in vehicle accident resulting in major vehicle damage to right rear of vehicle from passenger door to the bumper.
Mileage the first time was 18,368 when I took it back to the dealer han graff chev durand michigan. Findings were "all four rotors had lateral runout beyond specs". They resurfaced front and rear rotors. Mileage second time was 31,038 and again I took it back to the dealer han graff Chevrolet durand michigan. Without even looking at it I was told that they would have to resurface or replace the rotors and questioned me if I was a 2 foot driver. Always blame the consumer--that was Smart. I took it to a reputable garage in my area and guess what again they had to resurface the front & rear rotors. I wrote to gm's ceo wagoner documenting all the facts and received a call from a young lady who told me "things wear out" .
Contact stated: having the same problem with brakes on car that investigation has been launched on. The brakes were gripping and vehicle kept going. Vehicle eventually stopped, but it took sometime to do so. Only happened in the winter.
