Wiring problems of the 2009 Chevrolet Impala

Abs and traction control lights intermittently come on causing car to jerk with acceleration, or occasionally, to slip during braking. Wheel hub assemblies have been replaced multiple times and the same faulty issue keeps reoccurring. Low quality wiring and position and tautness going into the harness are a recipe for disaster. Sensors can be set off with as little effort as gently rocking the car, definitely going off if there are any bumps or potholes in the road. Also had other annoying although less dangerous issues: door lock actuators and heating/ac actuator, causing door locks to not respond and causing a horrible clicking noise in the car, respectively. I have walked away from the car thinking I had locked it only to find one or more of the doors did not lock. Actually had items taken from the car. The clicking noise from under the dash was sporadic, usually upon starting the car, but occasionally while driving with no notice. This ear splitting, headache inducing noise would for the most part stop after several minutes of driving, but would sometimes continue after the car was shut off and would drain the battery. The electrical system throughout the car is horrible.

The Impala displays service traction control followed by engine power reduced. Throws a code for throttle body sensor, but that does not fix the issue. Accelerator pedal position sensor is another reason they say, which also does not fix the issue. My car has shut off on me going down the interstate, on a highway, and and over a hill. It shuts down and says �starting disabled, service throttle� with no warning at all. Several people have had the same exact problem and no one seems to know how to fix it. They say wiring but it never fixed anything.

Airbag light is on paid to get it fixed and it's still on afraid to drive it if I get into an accident it will probably not deploy the electrical system doesn't work my brake lights don't work to fix them and get new balls it's all electrical I seen there's a recall but I bought the car after the recall so I had no idea there was a recall for the electrical system wiring and the electrical system ignition my key gets stuck in the ignition and I have to push a button in the back in order for it to release.

We brought vehicle in for recall for wiring harness repair back in August because airbag light was on. Dealership wrapped the wires. 3 weeks later airbag light was on again. Brought back to dealership and they told us wires were damaged and wiring connector need to be replaced which was not part of recall. Paid $329. When I read recall online, it clearly states the wires should be inspected before applying the tape and if not wiring should be replaced for no charge. I filed complaint with gm and they contacted dealership who still says wires are not part of recall. Advised word for word of recall and no have to go to dealership with paperwork. My child is driving this car and was told by the dealership this is not a safety issue and we could have left it as is. Really?.
