2012 GMC Sierra 1500

This year drew an ordinary 197 complaints for a GMC Sierra 1500 — the model's median is 426. What they were about is the unusual part: 12.7% of them mention dealer where, against 3.3% across the other years of this generation.

Generation 1 of the GMC Sierra 1500, which began in 2007 and ran to 2013. Everything below compares this year against the others in that generation, not against a different car wearing the same name.

NHTSA opened a defect investigation into this model year.

What the complaints were about

Words owners used for the same problem are counted together, so a fault written four different ways is measured once. Grouped by which complaints they appear in, not by a list anyone wrote in advance.

How this was worked out

Every year of the GMC Sierra 1500 was compared against its own history rather than against other cars, which removes popularity and age from the answer — a common car draws more complaints at equal reliability, and an older one has had longer to accumulate them. A year is flagged when it drew at least 2.5× this model's median and at least 50 complaints.

This is a fault record, not a review. Nobody files a federal complaint to say the car was fine, so it shows what tends to go wrong — not whether owners liked it, and not whether it is a good car.
