UNKNOWN OR OTHER
I have only owned the vehicle for about 5 months now and well it just started seeming like the transmission is starting to slip while also making a noise and just struggling to find what gear to stay in. I have service the car per the gm manual and I don’t drive the car anywhere but to work and back and that’s it. So disappointing that in going to have to replaced the transmission so soon.

STRUCTURE:BODY
While driving on the highway, the passenger shock mount that is welded to the rear forward mounted crossmember snapped off due to rust. I have taken many pictures of the damage. I am a Master Certified ASE and Ford technician with my PA Emissions and Safety inspection licenses. I inspected the damage to my truck at my shop and removed the bed. I found further rust and damage at the drivers frame and rear shock mount at the rearward mounted crossmember. The whole rear frame section is rotting away. This caused the vehicle to sway heavily and change the driving attributes of the vehicle. I have not contacted police or the insurance company. There were no warning lamps of any kind.

STEERING
NHTSA Campaign Number: 14V246000 Q1- my steering column is faulty and it is on the verge of collapse. Q2- every time I hit a pot hole my truck loses control for a second and it has gotten progressively worse. The car sways from left to right without me moving the steering wheel. Q3- I’ve been having suspension problems that have become worse and worse after being told I’m having suspension problems. I fix what I am suggested too and the problems have worsened. Q4 yes it has been inspected and the issue has been overlooked. Q5 if I try to drive the truck again it will fail, I changed my rotors at the beginning of last month and the two front side rotors have been warped and replaced as of Saturday. I drove my truck just fine until tonight I began losing control of it two times. My brakes are beginning to fail. My brand new rotors have been ruined in less than two days. That’s 4 new rotors in a month. When I arrived at home I opened the hood and applied a very small amount of pressure on the steering columns shaft and it had a lot of play. I added a little more pressure and it moves a lot it felt like I could’ve taken it apart with my hands if I really tried. I’m pretty sure I shouldn’t be able to move the steering column shaft with only my hands if the truck is off.

STEERING
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.

ELECTRICAL SYSTEM
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

ENGINE, ELECTRICAL SYSTEM
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.
