The tailgate was automatically dropped while trailer was connected. Destroyed my tailgate. This should never happen.

I called to follow up and the reference number is #1516488, they told me to file the case online. I have copy of the letter I can resend via email or upload here.

Had two lifters collapse and fail. Replaced transmission twice due to torque converter failure

Shift to park will not work. Sometime after 20 try’s it may work once but I have to disconnect the battery to turn off the car. I’m beside myself and cannot keep doing this. This is a real safety problem. I have children in my car and Gm says there is no recall and I am expected to pay 800.00 and then it is not guaranteed.

The in cab brake controller does not work with electric over hydraulic trailer brakes. In my research to diagnose and fix the problem I find out GMC has known about this for years and has done nothing to correct. I pulled code C1114 and GMC issued a bulletin for part number (K58-036-00) which I purchased and still did not correct this issue. In short there are many 3500 trucks out there running with no trailer brakes. Here is the worst of this problem. If brakes are tested at a stop they appear to work perfectly however once driving this is when the error code is delivered to the truck so the brakes work at a stop when not needed and do not work under driving when they are needed. GMC has ignored this for years and after spending more of my hard earned money for a fix that did not fix the problem. Below I had to choose a date however this has been an issue since first purchase December 5th 2023 to present.

I was driving about 30mph and accelerated to pass a truck and the transmission failed and the car lost any ability to accelerate and I had to coast to the side of the highway and have the car towed to the dealer. The dealer stated the transmission would need to be replaced and it would be $9000. Mileage is 77,013. This is the third time the transmission has malfunctioned and caused the car to lose power on the highway. It has been repaired twice previously.

Vehicle stalls intermittently. Due to an earlier recall of the same model but not including the one I own. There is electrical shorting inside the fuse box in the ignition circuitry that causes this problem. This is a huge problem as there is no preemptive warning. Whether you're driving 5 mph or 55 mph it happens suddenly and without any warning. The incident is stored in OBDII codes. There are no warning lamps until after 5he vehicle stalls out. #PIT5643.

I experienced the loss of power steering while driving. It was almost impossible to steer the vehicle while driving. I went on line and noticed a recall for my exact vehicle of the exact problem. The recall bulletin 15595A, was dated February 2016 and explained that the steering gear torque sensor cover assembly was to be replaced. However, apparently my VIN number was not listed. I went to the dealer and it was diagnosed with Code C0545(power steering problem). The dealer recommended the same repairs as the recall notice. The dealer showed no interest in contacting GM to see if this can be fixed by this recall. They claimed because of the year and mileage that they would not move forward with this. I contacted GM myself and explained the situation. I was told that GM would not cost assist with this problem. I find it odd that GM recognized this issue as a real safety hazard on the same make, year and model of my vehicle and refuses to assist in the repairs. The mileage and year has nothing to do with this problem. The problem was and is an existing problem with this particular vehicle. This issue is a sporadic issue and and started approximately [XXX] and continues. I feel this problem is an existing problem with all of these year, makes and models whether the VIN number was listed or not!! It's an accident waiting to happen!!
