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

Once stopped trailer towing light luminated ( I was not towing anything). I exited truck and it was apparent this was a issue with the front brakes as they were smoking.

Vehicle has just over 113,000 miles and the frame is already severely compromised due to rust. Nearly all factory coating is gone. I believe the sub par wax like coating that GM used from the factory was never intended to last anywhere near or over 100,000 miles. I have personally inspected numerous 2007-2013 GMT900 trucks in or around ohio and have found similar severe rust issues. All vehicles inspected were between 60,000 and 120,000 miles. The rust issues are the worst in the areas directly in front of the rear axle where the frame drops. Nearly every vehicle inspected has structure compromising rust in this area. GMT900 platform vehicles with rust issues in this area are unsafe to be on the road, yet they remain popular in multiple service industries and are frequently seen pulling trailers. GM has done a great disservice to their customers by using a sub par coating on the most important structural component in a vehicle. These trucks should easily last well over 250,000 miles but due to poor coatings they have a hard time breaking 100,000 miles.

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.

We are unsure what happened that caused the issue. One day the dashboard just started giving us error messages, 3 of them to be specific. One says check turn signals, another says check trailer brake light and another something else about brakes or turn signals. (We have to dismiss them all before anything on the dash is viewable). This issue is causing the blinkers to blink fast as though the blinker lights need replaced and it happens when turning right or left. The alerts continue to give us error messages every few minutes, even after we have dismissed them all. We had the truck at a shop trying to figure out the issue and his guys spent hours and replaced things he thought were causing the issue but nothing fixed it. He referred us to take it to the dealership service shop for troubleshooting so we took it to the GMC dealer where we bought the truck. GMC has already spent hours, maybe 5-7 hours at $150 per hour, trying to figure out what's wrong and have been unable to find anything wrong. The truck is still at the GMC dealership shop but I can get pictures of the errors when we get it back.

- #11517938April 19, 2023AIR BAGS, STEERING
I left my vehicle for service (19 April 2023 - approximately 8:30 am CT) for an urgent safety recall to Bommarito West County GMC dealership located at 15736 Manchester, Ellisville, MO 63011 (Phone: 636-391-7200). When I drove the vehicle in the dealership and had not issues driving and steering. And when I picked it up at approximately 12:30 pm the same day the service consultant (Joshua Delanoix) did not bring the vehicle to me the same as I left it. Joshua asked that I pick it up in the parking lot, instead. I drove off the lot and noticed that the steering wheel would pull severely off to the right side when breaking causing the car to become unstable and steering towards oncoming traffic. I slowed down until I could retain better control of the vehicle to get home. Then, at approximately 4:30 pm, I drove back to the dealership and spoke to the same service consultant. He then referred me to the service manager (Pat Roberts). I explained to service manager that I could not drive the vehicle safely and requested a safety check. Pat refused to check the service work or the vehicle safety and disregarded my concerns. Afterwards, I spoke to the sales manager (Larry Buchhorn) and explained again my safety concern and he followed up with the same service manager and told me that there was nothing they could do and that the service manager's supervisor (Mike Simms) would contact me. Finally, I was allowed to drive out of the dealership with the same safety issue for the second time.

At 50,000 miles the upper control arm/ball joint on the driver side came apart with no warning causing considerable damage to the suspension, tires, wheel, and front bumper. About two months before at approximately 48,000 miles the passenger side control arm/ball joint came apart again with no warning. Warranty has just elapse and GM has denied any responsibility and will not cover any of the repairs. This could have easily been catastrophic if we would have been on the freeway. This is a Safety issue! This truck has the aluminum upper control arms which my opinion for what its worth is the problem. I have no clue at this time how we are going to be able to fix this. Even when it is fixed we will never trust it.
