GMC Sierra reliability by year
Each year is complaints filed in that year’s first 3 years on the road, divided by however many of those years have passed. A model year younger than 3 years is too early to compare, so it is left out of the years named as having the fewest or the most complaints. Recalls are a separate count. The numbers are for the US-market GMC Sierra. How we count.

Known issues for this generation
Recall 14V-719 covers certain 2015 GMC Sierra trucks (also Chevrolet Silverado, Suburban, Tahoe, and Yukon XL) with electric power steering: the EPS module can cause a sudden loss of power-steering assist. Dealers replace the power-steering assist motor kit. Recall 16V-651 covers certain 2014-2017 Sierra 1500 trucks among other GM models: the sensing and diagnostic module may not operate properly, which can prevent frontal air bags and seat-belt pretensioners from deploying. Dealers reflash the SDM or replace it after a prior deployment. Recall 19V-645 covers certain 2014-2018 Sierra and Silverado trucks: mechanical vacuum-pump output can fall over time, reducing brake assist; dealers reprogram the electronic brake control module. Recall 24V-756 covers certain 2018 Sierra 1500 and Silverado 1500 Crew Cab trucks (and HD Crew Cab 2018-2019): a roof-rail air-bag inflator end cap may detach or the inflator sidewall may rupture; dealers replace the left and right roof-rail air-bag modules.
