We bought this 2002 Chevrolet Impala in April of 2002. Fortunately, we purchased the extended warranty. We have had continuous problems with the traction control system. Initially, the warranty covered the malfunctions: Wheel sensors, modules, brake pump, wiring, etc. Were replaced. Shortly after each repair, the system failed again. When the warranty expired we continued to experience system malfunctions, replacing part after part. To date, over $3.5K has been spent to attempt to fix this poorly designed and installed system. It has been out of service for more years, than it has functioned. It has been out for the last 3 years, because we can not put good money after bad. I recently contacted GM corporate with my complaint and they told me to take it in for system diagnosis. Same result: Brake pump and module out, with possible wiring problems and wheel sensors. Estimate to try to fix: $2.5K. No guarantee it will work. This malfunction occurs with no warning: Sometimes upon starting the vehicle, while driving or turning. I investigated this problem online and found many others have experienced similar problems, not being able to get them fixed properly. It occurs in Impala and monte carlos of similar years, 2002-2008. How can GM justify spending $6K to maintain a single system which works directly with the ABS brake system? my contact at GM is [xxx] 855.880.1500 ext. [xxx]. Chevrolet needs to do a recall on this faulty, poorly engineered system. Please investigate. Thank you.

I was driving with my son and the car just cut off in the middle of the street. Thank god we didn't get hit. The car cut back on but that was scary. It (the car) also has some type of security feature that won't allow the car to start at times.
