What Problems Does the 2012 GMC Sierra 1500 Have?
The 2012 GMC Sierra 1500 series has fewer problems than other full size trucks on the market. There are also a lower number of owner complaints compared to both the 2011 and 2013 models.

Interior problems, including cracks in the dashboard, are another complaint from owners. Usually if the truck is parked outside, the heating and cooling will cause the dash to expand and contract, leading to cracks.

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.
