Brake rotors have been turned 5 times on a 2005 Chevy Uplander and need to be turned again. Steering column needs to be rebuilt from the constant vibration caused by the warped brake rotors. Have talked to several people who own Uplanders, who have experienced the same problems. Have read numerous complaints on-line concerning the same problem. Can not get a response from GM concerning the issue. Needs to be a recall before someone gets hurt.

Brake rotors warp on regular basis. 4 times in 20,000 miles (2 years). Unless replaced van stops with difficulty and could result in crash.

Since purchasing this vehicle in January of 2006 we have been required to make extensive repairs on an on going basis. The vehicle has to be aligned & balanced almost monthly which has resulted in us replacing the tires on 3 different occasions. The brakes have been replaced twice and the rotors have been turned twice in the past year. The most recent incident occurred 3 wks ago when my wife was driving home on a 55 mph 2 lane road when suddenly the check engine & check oil light came on. The vehicle just stopped. Upon towing it to a local auto repair shop we were informed the timing belt broke which warped the cam shaft. GM would do nothing until we towed it again, this time to a GM dealership. The vehicle was found to have extensive problems from the engine, to the timing belt, camp shaft, pistons, plugs and much more.

The brakes, when applied at highway speeds, will cause the front-end of the vehicle, including the steering wheel to shake violently. The dealer told me the rotors were warped and needed to be turned. The rotors have been turned on two separate occasions in less than a year at my own expense. I have been told by the service manager it is a recurrent problem - probably due to a bad batch of rotors. It is a serious safety issue since it occurs at high speeds and at times when proper braking is critical.
