2014 GMC SIERRA 1500 Complaints

The truck started making a grinding noise when turning steering wheel left and right. I took the truck to local GM dealer/mechanic for inspection. It was diagnosed as a failing steering rack and recommended replacing the steering rack. A failed steering rack can cause partial or complete loss of steering and potential vehicle accident. As of this time, GMC cannot provide a replacement steering rack and there is no estimated availability timeline.

Today I was driving on a residential road and my truck completely stopped while driving. My wheel locked up and I was unable to steer and almost hit another car. This has also happened a few weeks ago while driving on the highway at 70 miles per hour. My vehicle shuts off, I turn the key back and then restart it and I get the following 2 messages: 2 Keys programmed, and Open then close driver window. This is very dangerous and apparently a major problem with other vehicles as I have found the below additional details. This puts my family and others at major risk. I have asked to dealership to look at it but they state they have to keep it for several days and see the issue for themselves, and since it happens so sporadically I cannot be without my vehicle for that amount of time. Apparently it is an issue with the ground wires ands wiring harness. chrome-extension://efaidnbmnnnibpcajpcglclefindmkaj/https://static.nhtsa.gov/odi/tsbs/2017/MC-10113356-9999.pdf https://www.youtube.com/watch?v=gvpsaDm-jj4

What component or system failed or malfunctioned, and is it available for inspection upon request? How was your safety or the safety of others put at risk?: The truck just stalls and dies without warning, all lights go off inside and outside and all power is lost. From digging on the internet, I found out the problem is due to one or more rusty/defective connection to ground which stops current from flowing and therefore stalls the vehicle and turns everything off. When the truck stalls, power steering and power assisted breaks are not available and this makes the truck very difficult to guide/stop for most people, making it a significant safety risk to occupants as well as others as the likelyhood of a collision increases significantly. In addition, since all electric accessories are disconnected, warning/flashing lights can not be turned on to advise others that the truck has stopped. Has the problem been reproduced or confirmed by a dealer or independent service center? The problem is hard to reproduce because it happens at random times, it has happened to me at least 5 times in the last month or so. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? NO Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? NO warning messages or other symptom.

I am losing engine power. My OBD2 gives me P2138 and P0700 codes. I have changed the accelerator and knock sensors.

In several areas on the exterior of the truck, the paint has bubbled and is peeling off. This is despite my efforts to really take care of my paint.
