2015 Gmc Sierra 2500 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.

- Date Of Incident: 2024-03-07
- VIN: 1GT12YEG1FF
- Components: POWER TRAIN
- Summary: The truck is a 2015 GMC Sierra 2500 HD. With less than 51,000 miles, the transmission is gone due to a design flaw. Around march 8th, the transmission went out when I hydroplanned on a two lane road. Haley GMC Airport was wanting $6700 for a new transmission. I contacted GMC and they offered a 15% discount after raising the price to over $7500. GMC has replaced and volunteered recall on their 2015 1500 and 2015 2500 8 speed transmissions but will not do anything about the 2015 2500 6 speed transmission. The transmission where I received a second opinion advised that they changed the transmission on the 2015 after realizing there was a design flaw. I feel that myself and many others whose transmissions died before 100,000 due to GMC design should not pay full price for a new transmission. If this is not the correct channel, please let me know. thank you.

- Summary: General Motors LLC (GM) is recalling certain model year 2015-2017 Chevrolet Silverado 2500 HD, 3500 HD, Tahoe, Suburban, GMC Sierra 2500 HD and 3500 HD, GMC Yukon, GMC Yukon XL, Cadillac Escalade and Cadillac Escalade ESV vehicles and 2014-2017 Chevrolet Corvette, Silverado 1500, Trax, Caprice Police Pursuit Vehicle, GMC Sierra 1500, Buick Encore, and 2014-2016 Buick Lacrosse, Chevrolet Spark EV and SS vehicles. In the affected vehicles, certain driving conditions may cause the air bag sensing and diagnostic module (SDM) software to activate a diagnostic test. During this test, deployment of the frontal air bags and the seat belt pretensioners would not occur in the event of a crash.
- Consequence: A failure of the front air bags or seat belt pretensioners to deploy in the event of a crash necessitating deployment increases the risk of injury to the driver and front passenger.
- Remedy: GM will notify owners, and dealers will reflash the SDM software. Vehicles that have had a previous air bag deployment will have the SDM replaced. These repairs will be performed free of charge. The recall began on October 13, 2016. Owners may contact Buick customer service at 1-800-521-7300, Cadillac customer service at 1-800-458-8006, Chevrolet customer service at 1-800-222-1020, or GMC customer service at 1-800-462-8782.
