Which GMC Sierra Denali years should you avoid?
On raw complaint volume the 2016 is the weakest year on record, with 30 complaints concentrated in the power train.
Read these numbers with sales volume in mind. A model year that sold in huge numbers naturally accumulates more reports than a rare one, and older cars have had more years to fail. The stronger signal is the severity columns and whether the same component keeps coming up year after year.
