2012 Gmc Sierra problems

gmc logo

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.

Common 2012 Gmc Sierra problems

The 2012 GMC Sierra 1500 is a full-size truck known for its excellent long-term dependability and upscale cabin. However, like any vehicle, it has some common problems that owners have reported.

Excessive Oil Consumption

The most common problem with the 2012 GMC Sierra 1500 is excessive oil consumption. In some cases, the oil consumption is normal for the engine, but in others, replacing the oil pump valve cover is necessary. The cost of replacement can be around $300, depending on local labor rates.

Interior Problems

Another common problem with the 2012 GMC Sierra 1500 is interior issues, including cracks in the dashboard. This issue usually occurs when the truck is parked outside, and the heating and cooling cause the dash to expand and contract, leading to cracks. Replacing the dash can cost around $1,000, or a dash cover can be purchased for $75 to $100.

Electrical System Problems

Electrical system problems, such as stabilizer failures, are also mentioned, but are rarer than the other complaints. Replacing the steering wheel position sensor solves the problem, costing about $400.

Paint and Trim Problems

Paint and trim problems, such as paint peeling away from the metal, loose interior or exterior trim or moldings, rust, and chalking, are also common issues with the 2012 GMC Sierra 1500. Owners have reported that the factory tow hitch rusted out, and undercarriage rust made the truck unsafe, costing $6000 to fix.

Transmission Problems

Transmission problems, such as transmission minor and transmission major, are also mentioned, but are less common than the other complaints.

Engine Problems

Engine problems, such as leaking coolant from a cracked intake manifold gasket, are also common issues with the 2012 GMC Sierra 1500. Most experts agree that the problem stems from GM's 'DexCool' coolant, which erodes away at the intake manifold gasket.

Excessive Oil Consumption in the 5.3-L V8 Vortec 5300 Engine?

The lawsuit says GM 5.3L oil consumption problems are caused by defective piston rings, PVC systems, and "active fuel management" (AFM) systems that cause the spark plugs to wear out prematurely and the engines to experience all kinds of malfunctions. The problem may be due to low-tension oil rings and a new PVC system, both of which are allowing too much oil to enter the combustion chambers to burn off early.

In summary, the 2012 GMC Sierra 1500 has some common problems, including excessive oil consumption, interior issues, electrical system problems, paint and trim problems, transmission problems, and engine problems. However, it is essential to note that these issues are not unique to the 2012 model year and have been reported in other years as well.
