STRUCTURE:BODY, UNKNOWN OR OTHER
Vehicle does not have a notification via chime or message stating the rear tailgate is open. There is a button on the dash that can open the tailgate when the vehicle is stopped at an intersection, this can be inadvertently pressed without the driver knowing, causing the vehicle to drop any cargo when accelerating or leaving the intersection. This can lead to serious injury or to any vehicle behind it. Many owners have already reported losing cargo such as tool boxes, paint cans and groceries spilling throughout intersections.

TIRES:TREAD/BELT
The right rear tire (Goodyear Wrangler 275/65R20) separated and blew out on the highway, the truck was very difficult to control however it was safely stopped and there were no injuries. There was no observed warning prior to the blow out. The tire separation caused damage to the right rear quarter panel. The spare was installed and finished the trip safely. A tire shop found a second tire with evidence of separation on the left front corner. The tire that blew out on the highway is (DOT PJOT JB1V 0721) and the other 3 including the one with evidence of separation is (DOT PJOT JB1V 0821). The blown tire has been returned to Goodyear in Ohio by the auto repair facility at Goodyears request. Goodyear is refusing to assess the other 3 tires unless I bring them to an authorized service center which is not possible with only 3 functional tires including the spare. The 3 remaining tires are at the auto repair facility.

ENGINE
Truck started to jerk if driven over 20 mph. Before this the dashboard (electric) notification showed truck heating up but the temperature gage was not reading any overheating. Prior to this the whole electrical system in the truck started to mess up. The radio changed channels without actually changing the radio channels. Unable to connect the Bluetooth because it calls my phone contacts at random. Had to get a new transmission that cost 5,000 and this was recent. The truck is still jerking but is drivable over 20 mph.

POWER TRAIN
I am having a issue with a low milage GMC Sierra. The truck is a 2015 with 24,000 miles. When it was produced the truck had a 100,000 mile warranty but has since lasped in time. The transmission on this truck is a 6l90 which has had several know issues that gm is aware of. This service bulletin is just highlight of the issue gm bulletin 19-na-153. I've talked with several transmission shops and event saw a few posted online about the transmission issue, my issue is gm will not stand behind their product, I have contacted GM directly and gotten no where. During my conversation with the GM reps on the phone they did agree the transmission should not have blown at the milage. My truck is garage kept, doesn't go outside in the rain or snow. I know there is a class action for the Allison transmission and the 8 speed but not the 6 speed that I'm aware of.

UNKNOWN OR OTHER
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.

SUSPENSION
I was driving the vehicle heard a loud thumping sound got out to look and the driver side tire was nearly off the vehicle! Had I been driving on the highway I could've been killed/seriously injured by loss of control by way of steering. It looks like the upper control arm completely seperated from the tire at the ball joint causing the tire to fall away from the vehicle. There is a current recall out there for this make, year, and model. The vehicle has been inspected by the manufacturer. No warning lamps or messages have appeared.

POWER TRAIN
Transmission is slipping into neutral from a slow start and re-engaging with a hard bang to the point it feels like I’ve been rear ended from a vehicle behind me. It’s done it twice in two weeks and it seems to happen when I’m leaving from a stop or slowing down and then come back into the accelerator.

SERVICE BRAKES
We were hauling a trailer and driving approximately 65-70mph with cruise control enabled. The vehicle randomly disengaged cruise and the ABS telltale illuminated, lost brake functionality completely. Safety of my family and other vehicles around us was compromised! Downshifted to try and navigate the vehicle to the side of the road and the ESC warning text came on the screen. Was able to luckily stop vehicle by downshifting. Turned off ignition and then cycled back to run, brakes and all warnings were cleared. Started driving vehicle with flashers on the side of the road see what would happen and approximately ten miles later same thing happened but this time brake functionality was reduced significantly but not completely but still had to downshift to stop. Called GMC and was told this was not a recall even though vehicle brakes randomly stopped working. Told us they would do nothing since the vehicle was out of warranty 80k miles and warranty was 60k and also since no one was hurt. We were 1-2 hours from being in the Mountains driving and not sure we would be here today if this had happened in the Mountains! Dealership ordered a new master brake booster and ABS. When installed the part would not flash and GM engineering told them to replace the part a second time.They we’re told to keep flashing till it takes even though the second module was also bricked. Seems strange a new part would be broken as well and the master cylinder was resetting. Dealership states the vehicle is fixed but the safety of my family and others driving around me were in extreme danger when this happened. Do not feel safe driving this vehicle and not convinced this will not happen again. When we called GM they told us they are receiving many calls about this happening to AT4 vehicles but they have not issued a recall yet. Submitting this because vehicles should not randomly lose brake functionality and do not want others at risk or my family.

SERVICE BRAKES
The factory Installed Trailer Brake Controller - The brake controller disengages the trailer brakes after multiple applications of the brake pedal. If the ignition cycle is stopped and restarted brakes are then reconnected. The Truck is equipped with a Max Towing package and factory installed brake controller. Prior to disengaging the trailer brake, a message "Check Trailer Wiring" appears each time the brake pedal is applied, then after multiple brake applied, the message" Service Trailer Brakes" message appears and the trailer brakes are disable for the remainder of the ignition cycle. I had the brake controller serviced at a GMC dealership In Hillsboro, Oregon following the first failure of the system, they advised me that the problem was the trailer plug on my trailer and advised me of brand and model number to install on my trailer. After I installed this new plug problem remained. I then to the truck to the dealership where I purchased the truck in Salem, Oregon. After an inspection there I was informed that it was a wiring issue with my Canopy and that they had fixed it. Again the problem wasn't fixed and the brake controller continued not to work. On my next visit for the same problem I was advised that my trailer was the issue and that the truck wasn't the problem. So I took my trailer into a top tier trailer repair shop and everything on my trailer was functioning as designed with no repair required. These 3 visits were over a period of 14 months. Over this 14 month period I had two close calls while towing my boat and trailer. What I have now learned is that the factory installed brake Contoller is not compatible with my trailer electronic brake actuator, even though all of GM promotional information says that it is. In addition none of the GMC service representatives were aware of this problem. I had to point out an obscure bulletin to them. by GMC failure to advise owners of the problem many drivers are being put in harms way. GM needs to inform
