What are the best GMC Sierra Denali years?
The GMC Sierra Denali years with the fewest complaints on file are the 2012 (10), 2010 (10) and 2020 (11). Model years after 2023 are left out: they have not been on the road long enough to compare.
NHTSA does not publish sales figures, so these are complaint counts, not a rate per car on the road. A year that sold more cars collects more complaints, and older years have had longer to collect them.
