My Service Traction System light is continuously coming on. When I go to brake or turn the wheel going around curves or downhill there is a very nasty grinding noise. I've replaced brakes and rotors still the same thing I'm lost. I don't know what to do?

Replying to: leta789 (Apr 28, 2009 1:54 am) My son's 2003 rendezvous has the same "similar" problem. When you turn the wheel to the right and apply the brake the pedal jumps and after a few times the ABS disables and the AWD light comes on too. They have had two wheel sensors replaced on the right front wheel and it still does it. It seems to be getting worse. Once the ABS and AWD lights come on it drives ok. Is this dangerous?   My Son, Daughter in Law and 2 Grandchildren are in this vehicle??? Also they have replaced the intake manifold gasket, head gasket, and water pump. GM engineering at its best....... Replies to this message: ray80 (May 12, 2009 5:03 am) pondfishr (May 12, 2009 5:16 pm)

Replying to: leta789 (Apr 28, 2009 1:54 am) For the grinding noise it is likely a wheel bearing. For the service traction,ABS,AWD lights it may be a wheel speed sensor (also part of wheel bearing/hub assembly), or fairly often (more so if it created by certain driving condition like going around corner) it may be problem with connection to sensor. It may be corroded or loose and I believe I've heard of a newer version of wireing that may be a bit longer so its not stretched when turning.

Replying to: pondfishr (May 11, 2009 12:45 pm) See my prior post for possible corrections to the problem.   'Is this dangerous?'   No more so then the thousands of other vehicles that are on the road without ABS or AWD. The lights just let you know you are among them without the added features. Replies to this message: pondfishr (May 12, 2009 5:16 pm)

Replying to: ray80 (May 12, 2009 5:03 am) Do you know what you need to disassemble and where on the wheel you need to look to see if the sensor connection is loose or a bad cable? Thank you for the help!!

Mine was result of bad hub bearing on left front side - it was worn so bad the sensor could not pick up signal. By the way Bucik had recall for bad bearings, guess they never told me and you. Now i just replace rt one, thank goodness i have extended warranty = $400, twice $800.          good luck
