Service ABS light stays on.we have had the van in for service now over seven times for this problem, the last one being today...08/21/2009. It still is not fixed. It occurs when we have three people in the van with the third sitting behind the driver. Numerous sensors, hubs, and wiring harness' have been replaced but the problem is not fixed.

ABS light came on and I took the vehicle to my mechanic because the warranty expired 2 months ago. The sensor had failed causing my ABS light to come on. I had to replace the left front wheel assembly just to fix the sensor. It cost me $250 for the part and $120 for labor. I called the dealer and was told that if it were under warranty it would have been covered. I contacted GM directly and tried to plea my case for a refund or a partial refund and was told that because I went to my own mechanic there was nothing they would do.. my vehicle is only 3 years old and has only 21,400 miles. The mechanic said he had trouble getting the part because the vehicle is only 3 years old and this usually doesn't happen.

I have a 2006 Chevy Uplander lt and I started to have problems around 3,000 miles of ownership. It started with electrical issues (hard drive entertainment system, gas gauge, dimming lights, radio losing settings, hard starts, service ABS, and service traction control) and gradually moved to mechanical issues (clucking noises " front end, vibrations " front end, steering binding, and grinding noises from the front end). What has been replaced in hopes of fixing the issues are the hard drive to the entertainment system, main computer module (twice and reprogrammed several times), steering column, steering box, rack and pinion, front stabilizing control arms, front brake, front rotors resurfaced, ABS control module (never fixed the service ABS and service traction control). The dealer still can?T explain the grinding noise and is trying to convince me that it is normal characteristics of the van (they actually wrote that in the service report). They can not resolve the service ABS and traction control errors. They can?T resolve the hard starts. The dealer has taken a position that no more diagnostic work will be performed to the front end until I replace a cupped tire (their opinion). I have hired a lemon law attorney to help with my problem.
