As I was driving down the road the front upper lip of my grill blew off and hit my windshield and then flew into car behind me. Looked online and this is a very common theme with GMC built in 2021 & 2022.

STRUCTURE:BODY, ELECTRICAL SYSTEM
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.

ELECTRICAL SYSTEM, VEHICLE SPEED CONTROL, BACK OVER PREVENTION: WARNINGS
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.

EXTERIOR LIGHTING, UNKNOWN OR OTHER
The reverse lights and high-definition camera system are woefully insufficient for backing up this truck safely in the dark. I have experience several near-misses due to the poor nighttime performance of the video system and reverse lights. This has been ongoing since the vehicle was purchased new. It impacts both the video displayed in the main touchscreen and the video rear view mirror. Furthermore, the reverse lights are sealed LED units that are non-serviceable.

ENGINE
While driving the transmission lurches forward when I give it gas after slowing down or when I come to a complete stop. Also it makes a shuddering type noise randomly when driving and it feels like the truck is about to shut off. These issues happen on multiple occasions.

WHEELS
No accident happened as the wheel was never installed due to not meeting the load weight capacity rating of the vehicle. The wheel is marked max load 1150kg (2230 per axle) and the vehicle weight loading label shows the rear axle capacity at 2706kg. The wheel is also marked as SAE J2530 compliant but does not meet J2530 section 3.5 due to the low load capacity. These wheels are widely available in the aftermarket and list most of the 2000-2010 GM 2500HD/3500 pickups as the application but do not meet load capacity on any of them. Please note that the VIN is for a typical 2008 Sierra 2500HD pickup in a scrap yard. I do not own that vehicle. It is a weight label photo from Hollander parts finder on that pickup.

ELECTRICAL SYSTEM, SERVICE BRAKES
The brakes sometimes lock up after use, or don’t disengage ( on one side) and the truck swerves ( steering wheel turns to the right ) into the next lane. I have to over correct and you can hear the brakes squeal. I will have to get off the freeway or the road. I am on trying to track off a couple of times for 5 to 10 minutes Until it stops doing it. It does it on average once to Twice a day. Was told could be brake calipers hoses, speed sensors sending the wrong information to the ABS system. It is very dangerous to drive the truck on the freeway doing 75 miles an hour!

FUEL/PROPULSION SYSTEM
i began getting a service engine light that went on and off a few times randomly. the vehicle would not switch down to 4cylinder as designed. there was an odd shudder as the vehicle slowed at 10mph increments which would randomly happen or not happen dependent upon the moment. i was outside of warranty so i went to a shop which has been very good in the past as opposed to risking dealership costs on top of the fact the dealership had no availability for quite some time. ultimately, i ended up replacing all fuel injectors and related equipment at my own expense. just happened to be online looking around after the announcement of gm reimbursing for similar issues on larger sierra engine and ran across a bulletin that only went to certain states in order to replace these injectors as they failed or reimburse for costs up to 10 years or 150000 miles from the time they were put into service. just curious as to why this happened in some states and not others when there was obviously and issue. i know this is probably not the forum, but a complaint is a complaint.

The Backup Camera is worthless. You cannot see at night to back up your vehicle. Only can see Dark and Red Spots. Impossible to see what is behind the vehicle.

UNKNOWN OR OTHER
Rear sliding window has a leak. While washing the vehicle or if it rains, water penetrates threw the window and into the inside headliner causing water stains and mold. Water also runs down the inside of the back window to the floor carpet, also creates water stains and mold. General Motors has a Bulletin 18-NA-383, Which does not fix the problem, but only puts a temporary patch. The permanent fix would be to replace the whole window.

FUEL/PROPULSION SYSTEM
Bought the vehicle new in 2019 currently at a dealership to have the third in tank electric fuel pump installed. When it was in the shop for the second fuel pump installation the technician informed me that the pump can go out at any time causing a potential accident. Fortunately truck wouldn’t start and was diagnosed at dealership.

The top part of the grill flew off while driving down the freeway and almost hit another car. Look at forums this is a very common issue and GMC needs to recall it.
