On December 21, 17. My vehicle had this happen to me.
Wow thought it was just a simple recall fix I had fixed on November 1, 2017. Oh they say it’s fixed But was I wrong. Last Thursday this happened to me When I was turning off of Kings rd in Clt Nc. Scared to death to drive my truck now. Last week out of no where the truck turns off, steering wheel locks while I’m turning and I have no control while I’m driving. Gm needs to buy back my truck. Truck is at dealership now. What do I do. No wonder I can’t sleep. Worried
I am talking with GM and waiting to see what they are going to do ????????.

Product Safety Recall 17276. Loss of Steering Assist Reprogramming. I called the nearest dealer for an appointment. On Friday October 27, 2017 I delivered my GMC to the dealer for the recall fix. My route was all smooth, paved roads at the posted speed limits. The limit was 70 mph on the highway portion. About three miles. About five miles total drive. I experienced no problems with steering or anything else. I left my vehicle for servicing and returned that afternoon to pick it up. I was notified by phone that my vehicle was ready to be picked up shortly after I left it there for the recall. When I picked my vehicle up I drove the same route to return home. At 70 mph I experienced a slight vibration in the steering wheel and a funny noise that I had never heard before. I turned around and drove back to the dealer. I told the Service guy that there was something wrong and explained. He said something about all they did was program a module. I said my vehicle was not doing what I described when I brought it in. He went to find someone to test drive. I went with the guy. He said he did not feel anything and said I probably needed to have my front end aligned. Back at the dealership there were three people waiting on me. One was probably a supervisor. He was more interested in covering the dealership than my problem. I felt intimidated with the three there waiting on me and felt like they were trying to cover their rears for some reason. I left with their statement that all that was done was reprogram a module. Has anyone else out there had a similar experience with this recall fix?
