Wiring harness is defective and friction causes electrical misfires that affect the entire vehicle, from deacceleration while driving to not being able to turn over the engine to start. I've been dealing with this issue for over 4 years and gm nor any safety commission will do anything in terms of a recall. This complaint is the only recourse that I have in order to notify public of the issue. This is extremely concerning as it can cause safety hazard on road.
Faulty wiring harness for the stable link system front driver side. While driving the vehicle the check engine light will come on along with the stable link system and lose power to the engine and shut down.
Service abs/stabilitrack is displaying often. Grinding noise, decreased power and car will nearly stop on you from time to time, particularly when turning. Taken to dealership, more than once, they get no codes on diagnostic. I believe this is a wiring issue. However, this defect is found in many years of the same make of vehicle. At times when turning, the stopping of the vehicle could harm or kill me or my family. There is bound to be lawsuits if this is not recalled. A search online produces hundreds with the same issue.
