2008 Gmc Sierra problems
The Chevrolet Silverado is a range of trucks manufactured by General Motors under the Chevrolet brand. Introduced for the 1999 model year, the Silverado is the successor to the long-running Chevrolet C/K model line. Taking its name from the top trim level from the Chevrolet C/K series, the Silverado is offered as a series of full-size pickup trucks, chassis cab trucks, and medium-duty trucks. The fourth generation of the model line was introduced for the 2019 model year.
The Chevrolet Silverado shares mechanical commonality with the identically related GMC Sierra; GMC ended the use of the C/K nomenclature a model generation prior to Chevrolet. In Mexico, high-trim level versions of the Silverado use the Chevrolet Cheyenne name (not to be confused with the 2003 concept). Competing against the Ford F-Series, Ram Pickup, Toyota Tundra, and Nissan Titan, the Silverado is among the best-selling vehicles in the United States, having sold over 12 million trucks since its introduction in 1998 as a 1999 model year.
History
The Silverado nameplate made its debut for the 1975 model year, becoming the top trim level on all Chevrolet C/K trucks, slotted above Custom Deluxe, Scottsdale, and Cheyenne. For the 1968 model year (seven years before the Silverado), GMC C/K trucks used variations of the Sierra name (Sierra, Sierra Classic, Sierra Grande, and High Sierra). Even after the C/K series officially ended, GM still uses the CK and the CC in their current model codes, to denote a two-wheel drive (CC), and four-wheel drive (CK).
For the 1988 GMT400 model architecture, Chevrolet retained the C/K model nomenclature, with GMC branding its full-size line as Sierras. While sharing the same body and chassis, the model chronology of the Silverado and Sierra are different, with five generations of the Sierra, while four of the Silverado.
In 2018, at the NTEA Work Truck Show in Indianapolis, Indiana, Chevrolet unveiled the first medium-duty Silverado, expanding the model line to a 4500HD, 5500HD, and 6500HD chassis cab. Largely the successor to the 2003–2009 GMT560 chassis, the medium-duty trucks are exclusive to Chevrolet, with no plans for an equivalent GMC version. Instead, Navistar International (now partnering with GM) would sell the medium-duty trucks as a rebadged counterpart, called the CV. This is in fact a very similar nod to how the Avalanche did not have a GMC Yukon–based equivalent, but instead, Cadillac would take its place as the former's rebadged counterpart, the Escalade EXT.

WHEELS PROBLEM
- Date Of Incident: 2024-09-10
- VIN: 1GTHK29688E

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.

- VIN: 1GTEC14X98Z

The tires were purchased sometime in 2018 and are a little above the 50.000 mile warranty. They were inspected by NTB technicians in Lancaster and also in Canal Winchester Ohio. They will only replace one tire for free but l think and believe l can’t be the only one with 4 of these tires failing in the same vehicle. All four tires have failed. No inspection by police or insurance has been performed. No warning signs at all other l got under the vehicle to inspect a small oil leak and that is when l saw the problem. I want to reiterate, what are the odds am the only one with all four tires failure?

SEAT BELTS PROBLEM
- Date Of Incident: 2022-01-10
- VIN: 2GTEC13C881
- Components: SEAT BELTS
- Summary: I started my 2008 GMC Sierra, crew cab and began to pull my drivers side seat belt across my body to latch it. I was about 1/2 way when I heard a loud bang that sounded like a gun going off to my right, the seat belt that I had in my hand pulled back tight pulling my hand with it. There was smoke and the smell of gun powder coming from the bottom of the passenger seat by the seat belt. With my heart pounding in my chest I got out of my truck as quickly as I could (my driver's side door was still open). Both the driver's side and passenger side seat belts were pulled tight and I was unable to get either to release. The truck is now sitting, unable to be driven safely with the seat belt on. The dealership said it would be just under $1,000 to fix plus towing and has no idea how or why it happened. This truck has never been in an accident and currently has about 140,000 mostly highway miles on it and I am the original owner. Searching online I found that there are other people on blogs who have had similar problems with exploding seat belt modules with a range of 40,000 miles to over 150,000 miles.
