I was driving and the transmission control module failed, putting the truck into limp mode with no prior warning. This was a hazard to myself and other drivers as it happened on a very busy road. I use this truck to pull our fifth wheel camper and luckily we were not pulling the camper at that time or this could-??ve been a lot worse with the truck just stalling putting my families safety at risk and being broke down in the middle of nowhere. I took the truck to a repair shop in the city that I live in and it was confirmed that the TCM was bad. Tried to order a new TCM and they are back ordered for months and even over a year. Had to send it into a company in South Carolina for repair of the TCM with a cost of approximately $1300. There are thousands of people with this issue, and this should-??ve been addressed by GM and a recall sent out to the owners of the vehicles. After the truck went into limp mode, there was a error message but no other prior warning.

The TCM failed while my husband was driving the pick up and this also set off the posi traction control and stabilization link. The truck has fluctuating shifting and could have cause a wreck if there had been someone behind him because the speed dropped on the tuck and it the transmission can't shift properly or consistently for safe driving. The part has been on nationwide backorder for over a year.. this truck can not function properly with out this part. Calling the dealership there are many vehicles affected with this problem and no estimates time of part arrival replacement. The dealership knew exactly what the problem was when called but didn't recommend dropping the truck off as there are no ETA on replacement. Their recommendations is to research online to try to have the part repaired. No the part has not been inspected as it it unsafe to drive at the moment and there are no available replacement parts for the TCM at this time. The warning lights did not come on until the part failed to allow the transmission to shift. Per some people on a face book group this has apparently been a known issue with this part since 2011.

Dash is cracked in multiple places. Dash is not structural however loose shards of plastic pose a serious safety hazard if they were to come loose as a the result of a sudden change in acceleration. Vehicle is low milage with 130k miles, previous owner failed to report or repair the failed dash prior to my ownership. It is a common failure on GM vehicles however it is very expensive to repair, unwarranted, yet poses a serious safety hazard. Dash will need to be repaired to ensure the safety of me and my family.

I purchased a vehicle that was advertised as having 52000 miles on the odometer. I looked at the vehicle and ended up purchasing the vehicle for 24,500. The vehicle was as it appeared as advertised. The seller provided a copy of a carfax report which showed the vehicle had 52000 miles on it with no damage reported, however I was unable to run my own carfax at the time of purchase due lack of internet access. Later on after the purchase I was able to look up my own carfax and it showed that the vehicle had 314,635 miles as the last odometer reading as well as moderate damage reported. I checked on autocheck as well and the same miles appeared but damage was not reported in this instance. I viewed the pink slip at the time as well and it appeared to be legitimate but after closer viewing where the last odometer reading was written it looked as if he had forged the numbers and changed them. I am unsure as to what to do at this point. I do not know how miles are on the vehicle and I don't know if there's anything else wrong or fraudulent regarding this. It would be greatly appreciated if I had someone help me out. Thank you.

My vehicle has 28,000 miles on it and my dash is cracking. It started cracking while on a cross country trip from California to Georgia. It is cracking in several places and I am afraid the plastic like shards could become projectiles if involved in a collicion.

Dash cracks around air bag always been garaged.

- Grantville, GA, USA

My dash is cracked around my passenger side air bag a and dropped down a little bit my concern if that air bag would open it could be a danger to me and who ever would be ridding with me. And on top of that it now rattles while driving which is a distraction, this started about 2 years ago and is getting worst.

Top of dash board is cracked in numerous places above the steering wheel, center of dashboard, and around passenger airbag. Worried that this would be a safety concern in the event of an accident. There would be sharp pieces of dash board being thrown around the cab and might affect deployment of passenger air bag. I have additional photos but they are over the 5mb limit

Cracked dash going from the passenger side airbag cover to the dash vent. Also, the mounting bracket for the sames vent clip is broken causing the dash cover to bounce around.

Dash is cracked near the airbag

- Selma, CA, USA

My dash has cracked around the passenger side air bag. If air bag deploys, it could send shrapnel towards the passenger. GM is aware of this problem but refuses to acknowledge or repair. Everett GMC told me they use to repair for $100. Now they want $1,600 and stated it would probably occur again due to cheap plastic parts installed by GM. My vehicle is garage kept.

Dash cracked next to passenger airbag cover. Vehicle was stationary when this occurred.

- Bloomfield, NM, USA

The dashboard in my 2013 GMC Sierra 2500hd has a crack that runs from the radius of the upper left hand corner of the passenger side airbag to the fwd edge of the dashboard that runs parallel to the windshield. The crack penetrates through the dashboard completely creating two separate sections with almost complete freedom of movement. Activation by the airbag will cause interference/contact between the device, and/or its components, and with the non-secured sections of the dashboard and most likely result in them being separated/dislodged and potentially launched in the cabin resulting in possible strikes to occupants. The vehicle was parked in my driveway with no crack and when I emerged the next morning and entered the vehicle, started the engine, the crack occurred. The mere potential for interference between the air bag activation and broken dashboard sections, obviously due to a poor, insufficiently tested design, (reliability testing?) should drive the engineers to revisit current risk analysis tools. It's clear the rpn for this type of failure mode in an fmea would not qualify under current industry standards.
