Car will not turn off and will display "Shift to Park". Similar recall on other models. This has gotten worse and happens most of the time now.

On multiple occasions, the vehicle has suffered from a severe computer failure. This results in the driver information center losing all data, the climate system shutting down, loss of all driver assistance features, loss of computer based safety systems, and prevents the vehicle from shutting down or being restarted until the batteries are disconnected. This results in the driver having no information about speed or engine parameters while driving. This error has not been reproducible by the dealer however they were able to assess it while one error occurred while driving by them. Their diagnostics show a complete failure of all 3 data buses and failure of the serial data gateway. Troubleshooting thus far has been unsuccessful. During the failure, all errors possible are lit on the warning lamps and the driver information center displays warnings for all vehicle modules. The attached photo was taken during one of the events after pulling off the freeway. While traveling at freeway speeds, the information on the screen was the same indicating no speed. This presents numerous safety risks.

On at least 5 occasions, my inner tailgate has released itself and gone down during motion. This has been uncommanded. It appears GM has a recall for this but it does not include my truck. The dealership that looked into it agrees this is likely the same issue and GM should include it in the recall.

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.

Vehicle caught fire minutes after remote starting. Fire appears to have started on firewall on the left side. We were about to take our kids to school vehicle could have easily caught our house and other property on fire. We did have the check engine light come on occasionally but it would always turn back off, vehicle only had about 12000 miles. Also none of the outlets inside the vehicle never worked.

Hello, I purchased my 2024 GMC 3500 AT4 Seirra late October 2023. Since the purchase date, I have been informed by motorist while at intersections my tailgate was down. I thought I was doing something wrong. On 3/3/2024 I was preparing to wash my truck and noticed my front amber lights were on surrounding my headlights. the vehicle was off, and my keys were in the house. Then my tailgate opener activated on at least 10 - 12 times. The tonneau cover is tight so the tailgate can need assistance opening. Nevertheless, the tailgate has opened on a number of occasions and my two front amber lights came on at least once. I reported this to my dealership on [XXX]. they said my truck has not been recalled yet but to watch this and if it progresses to call them. I noticed a small dent in the top rail of the tailgate on [XXX]. I have yet to put anything in the bed of the truck or even install a hitch in the receiver. I believe the tailgate had to be bumped when it was down by another vehicle, and this is absolutely related to the tailgate malfunction. since I haven't used the bed of the truck. Moreover, I feel GMC should be held responsible for the repair or replacement of my tailgate.
