The power steering failed while operating the vehicle. Unsafe. Local GMC dealership Haggerty in Oak Lawn, IL not able to diagnose problem after fact. My safety and others were at risk. Not confirmed, as techs are not familiar with system. No warnings prior to power steering failure. Be advised, this is a hybrid pickup, and as such, does not have a traditional power steering pump system. Other GM models from the same era have had recalls, but the Silverados and Sierras were somehow omitted. The power steering assist motor has failed. Not the "brains", module.
Heat sheald on exhaust manifold rusted and fell off engine resting on steering column locking steering momentarily untill I forced it to work.car was in motion when this happened.
Started truck up and let idle for two minutes. Upon take off, the traction control light came on and was immediately followed by the check engine light with a message stating engine reduced power. The truck then begins to run very rough and when the brakes where applied it violently and uncontrollably lunged forward. I pulled off the road, turned off the engine, and waited a minute or two. Upon restarting the engine, the check engine light came on but the reduced power message and traction light where gone. After sitting at a light for a few seconds, the symptoms where back, nearly causing me to rearend the vehicle in front of me. I pulled over again, turned off the engine for a minute, restarted and the same results as before occured. Now this happens every time the truck is running and sits in the same spot for more than two or three minutes.
While driving around a highway bend in the road the steering wheel locked up and would not move going 60 miles per hour. I'm a big guy and really used all my force to turn the wheel and final got to break free with a loud pop from the steering colum area. This has happened about six time since and I now have only 20,000 miles on it. I am a shop owner and ase master tech, so I know what I am reporting this is crazy dangerous.
