Traction Control Light On problems of the 2007 Chevrolet Impala

I have not had an incidence but very concerned about the malfunction that is going on with my vehicle at this time. . I noticed a scrubbing/grumbling noise when I would turn the wheel either way left or right. After vehicle being put on machine for testing it was discovered that the upper strut mounts and bearing were worn and noisy on front struts. . . . . . Also my abs and traction control light both came on at the same time and would not go off, the information system in vehicle recommended brakes be service. . . . . The results from car being tested showed both front hubs have slack and both front wheel speed sensor harness are coming apart inside wire installation. The codes for abs/traction control is. . . C0040 00. C0040.

My Impala's service traction control and engine power reduced lights came on 05/07/12 and I loss power to my car. I took my car in to a chevy dealership to have it serviced, I was told after they diagnosed it that I needed a new throttle body so I had it replaced for the cost of $647. 00 1 week later I was driving home and my car loss power and shutdown completely luckily I wasn't in heavy traffic and was able to pull over to the side of the road. I tried to restart it and white smoke came from the tailpipe so I had it towed back to the same dealership they told me after looking @ it that now I needed a new engine which would cost me $6200 I didn't get any lights on the dashboard or any other indication that I was having engine trouble and they cant tell me why it happened. I have my car serviced like clockwork @ the dealership spending good money for supposedly good quality service instead of some rinky dink garage but I guess that didn't matter. This happened just after warranty expired, I have 9100 miles and 3 car payments left.

The contact owns a 2007 Chevrolet Impala 3lt(na). The contact stated that while driving the vehicle from a stop light or stop sign, the tires spun out and the traction control light illuminated on the instrument panel. The failure occurred intermittently. The vehicle was taken to an authorized dealer but the failure could not be duplicated. The vehicle had not been repaired. The failure mileage was 6.

Abs & traction control service light kept coming on and I took it to dealership for service and they told me it was the hub assembly for the left side driver side that was covered under warranty and that I needed to replace my front rotors and brake pads (I wasn't having any problems with my brakes but because they said they needed replacing I went along with it). After repairs were completed and my vehicle "road-tested", I picked up my car and after leaving the dealership, both the abs and traction service light came on again and I called and they scheduled me in for an appt. 2 days later. They couldn't find the problem so they called and told me that they needed to dig deeper and keep my car overnight and that I would now be charged a diagnostic fee to diagnose the problem up to $100. My service 2 days prior cost $224. 90 so I was a little skeptical but I needed to know what the problem was so I agreed. I receive a phone call today stating that it is a wire in the harness that's causing the problem and it would be another $250. 00 to fix. I check the internet to find out more information and not only has this happened to me but to several others and obviously this is a manufacturer defect and should be covered and how do I know that the dealership didn't cause the problem/defect by digging deeper to find out why the service lights were coming on and damaged the wire.
