GMC Sierra 3500: Best and Worst Years by Complaints
Comparing the 5 GMC Sierra 3500 model years from 2008 to 2023 that have at least 25 NHTSA complaints, and allowing for the era and for how long each year has had to collect complaints, 2008 has the fewest complaints relative to a typical Sierra 3500 year and 2020 has the most. This reflects NHTSA complaint data only.
This comparison uses only NHTSA complaints, recalls and investigations. It is not a reliability verdict: complaint counts are not adjusted for how many cars were sold, and complaints are unverified consumer reports. An open NHTSA investigation is shown separately; it is not a finding.
