GMC problems by model
Owners have filed 51,763 complaints with NHTSA about the 20 GMC models with enough data to profile here, covering 168 model years from 1991 through 2026. The Sierra 1500 draws the most at 11,783, 22.8% of the make's total.
Complaint volume tracks how many cars a make sold as much as how they held up, and NHTSA complaints are unverified owner reports rather than confirmed defects. Nothing on this page compares GMC against another manufacturer. Use it to find the model, then the model year, then read what owners of that year actually filed.

Reading the numbers
Across every GMC model year on the site, electrical system is the system named most often: 5,418 complaints, 13.6% of those filed under a named system. Individual model years diverge from that sharply, which is the reason to read the year rather than the badge.
The three most-reported GMC models (Sierra 1500, Acadia and Yukon) account for 48.6% of the make's complaint volume. The rest is spread across the other 17 models. Bear in mind that a nameplate selling in the millions will out-file a niche one whatever its record.
Of the 51,763 complaints, 2,652 describe a crash, 750 describe a fire and 97 report a death.
