STRUCTURE:BODY
While driving down the highway at moderate speed (60mph), the deflector, top of the grill broke off the truck, hit the windshield and the top of the truck (causing paint damage) and flew into traffic behind us. The incident put my family's safety and other drivers safety, at risk. I took the truck to a dealership immediately afterwards and they indicated the 2023 version is not under warranty, although a recall exists for previous years for this exact issue. There were no warning lights or messages received prior to the incident.

STRUCTURE:BODY
The upper portion of the front grille is loose and about to fall off. I know GMC has a recall on some trucks for this issue, however mine is not listed on this recall although I have the exact issue as the recalled trucks. It’s just a matter of time before this comes off driving 70 mph on the highway and could strike a vehicle behind me causing an accident. I noticed this being loose back in June 2025.

ELECTRICAL SYSTEM, EXTERIOR LIGHTING
The entire instrument panel is blacked out. I can not see the speed, how much fuel and no waring lights etc. The screen flashes between black and dark blue and there is a repetative "ding" that I have no idea what is caused from since I can not see any warning lights, etc.This puts me and others at risk due to not being able to see any functions for operation of the vehicle, the speed or any indicator lights of vehicle issues. The dealer has seen the truck, and informed me that this is a known problem and they would have to order parts. According to the service department, parts for replacement will be covered under warranty/recall and they have been on order. It has been 3 weeks and they have no knowledge of when the parts will be in to make repair. There was no warning on this problem, the panel just went out.

POWER TRAIN, VEHICLE SPEED CONTROL
This issue is pertaining to the valve body in my 10-speed transmission. While I was traveling home, the truck experienced a “wheel lockup”. The transmission shifted down aggressively, then putting the truck into limp mode. I had to travel the rest of the way home with a max speed of 35 mph. I have been without this truck for 3 months waiting on parts. This is absolutely unacceptable from gm. Extremely unsave.

POWER TRAIN
Vehicle was in for routine service, oil change and tire rotation. Per the published engine recall bulletin [Manufacturer Recall Number N252494000] the recall directs the technicians to check for a DTC and if not present to drain and replace filter and oil using 0-40W oil, to replace the oil filler cap with new oil specification labeling, and provide a corrected page for the owners operating manual. All very simple steps. There is absolutely no reason for this check and service not to be performed during routine maintenance. GM is dragging their feet on performing a critical recall and should be held accountable for slow walking this recall. Servicing dealer claims they had ZERO 0-40W oil in the entire dealership. I can go to Walmart and get cases of this oil. Replacement Filler Caps, which must be replaced can be quickly produced by the tens of thousands if desired, which apparently is a very low priority for GM. Servicing dealer was Heritage GMC, Rockwall, TX. Desired outcome is to require completion of all outstanding recalls if the vehicle is presented for servicing regardless of reason. Further, to specify a definitive timeline to complete any outstanding recalls and have that information communicated to each owner. Manufacturer Recall Number N252494000 has not been completed at this time.
