Safety Issue:

General Motors, LLC (GM) is recalling certain 2024 Chevrolet Silverado HD 2500, 3500, and GMC Sierra HD 2500, 3500 vehicles equipped with power-unlatching tailgates. The tailgate's electronic gate-release switch may short circuit due to water intrusion, which can result in the tailgate inadvertently unlatching while the vehicle is in Park.

Potential Risk:
An unlatched tailgate may open and result in a loss of unsecured cargo, creating a road hazard and increasing the risk of a crash.
FREE Recall Solution:
Owners are advised to check that the tailgate is closed and latched before driving. Dealers will replace the exterior touchpad switch assemblies, free of charge. Owner notification letters were mailed December 17, 2024. Owners may contact Chevrolet customer service at 1-800-222-1020 or GMC customer service at 1-800-462-8782.

Defect Description:

SERVICE BRAKES

Potential Consequences:

Breaks and/or drive train. It is available for inspection. 1) Breaks sink causing slowed break time and decreased breaking ability. If the breaks are "pumped", more often than not, they will come back up to full pedal. However, in an emergency breaking situation, there is not time to "pump" the breaks. I was nearly in an accident recently when the break pedal would not stop the truck in time, due to the soft break pedal. I literally had to steer to the shoulder of the road. 2) When placing transmission in Drive or Reverse from the park position, then taking foot off of break pedal, there is about a 1 - 2 foot roll, then the truck stops as if the e-break has been engaged (but it is not engaged). By tapping the accelerator, it will "break free" (with a popping sound and a slight "jerk" in the truck) and then roll fine. This does not always happen ~ guestimate of about 10% of the time. 3) I don't know if this is related, but when I set the Drive Mode to "Normal", it automatically goes to "Off Road" ~ this happens no matter the driving conditions. This isn't safety related necessarily, however, it may be a part of the total problem.... It also decreases my fuel economy. I took the truck to the local GMC dealer/shop. They said the truck had 2 recalls and they took care of those. They believed one of the recalls would help solve the "sticking" when placing in Drive or Reverse ~ it did not. They also (supposedly) checked the breaking system and took it for a test drive. They said the breaks were fine. I doubt this happened as the soft break pedal and the need to "pump" the breaks to bring them to full pedal is completely obvious. I took the truck home after the inspection and recall. The same issues continued, so I took it back to the shop where it was inspected again. Again, I was told everything was in working order ~ it is NOT! There are no warning lights that I can find to indicate there is an issue. I'm begining to think that I should have bought a Ram Truck...

Potential Consequences:

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.

Defect Description:

ELECTRICAL SYSTEM

Potential Consequences:

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.

STRUCTURE:BODY

Potential Consequences:

1 - the failed component is the tailgate. The tailgate lowers automatically without any input from me while the vehicle is in operation. It has happened three times since buying the truck in February 2024. 2 - During the third event, I was backing up my Airstream trailer into its storage building when the tailgate dropped. At that time, I was negotiating a sharp turn in reverse and the tailgate came in contact with my trailer's propane tank housing. Both the tailgate and the propane tank housing were damaged (see photos). 3 - It was not until recently that I learned of a recall for the same condition on other trucks like mine, but for some reason my truck doesn't seem to be included even though it has the same condition as those trucks that are included. The tailgate and my trailer have not yet been inspected by any third parties (manufacturer, police, insurance, etc.), and no repairs have been made yet. 4 - There were no warning signals (either visible or audible) that the tailgate was down while the truck was in operation.

SERVICE BRAKES

Potential Consequences:

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.
