GMC Reliability — Frequently Asked Questions
How many NHTSA complaints does GMC have?
GMC has 62,314 NHTSA consumer complaints across 18 distinct models in the VinItel database (1995–present). 5.4% of those complaints involved a crash, and 137 involved a fatality. Source: NHTSA Office of Defects Investigation via VinItel.
Which GMC model has the most NHTSA complaints?
By total complaint volume, the top GMC models are: GMC Sierra 1500 (10,698 complaints), GMC Acadia (7,555 complaints), GMC Yukon (6,232 complaints). Note that higher-volume models naturally accumulate more complaints, so per-model severity depends on sales volume and crash rate. See the full sortable ranking at vinitel.com/stats/nhtsa-complaints/gmc.
What are the most common GMC problems?
Across all GMC models in the NHTSA database, the most-reported issue categories are: Engine Problems (5,395 complaints, 1.1% crash rate); Electrical Faults (4,809 complaints, 1.3% crash rate); Transmission / Drivetrain (4,074 complaints, 2.0% crash rate). Crash percentages indicate how often that component failure resulted in an accident — higher percentages are safety-critical.
Which GMC model years should I avoid?
GMC models with the highest severity scores include GMC Jimmy and GMC Suburban. Specific model years to avoid depend on the model — click any GMC model to see its year-by-year breakdown with complaint counts, crash rates, and recalls. Our AVOID label is applied when a year's normalized complaint rate exceeds 1.5× the model's median.
Which GMC model is the most reliable?
Among GMC models with at least 200 NHTSA complaints (enough data for a confident comparison), the lowest severity scores are: GMC Sierra 1500 (10,698 complaints), GMC Sierra (4,890 complaints), GMC Canyon (1,900 complaints). Lower complaint volume plus lower crash/fire/injury rates indicates fewer reported safety issues per vehicle on the road.
Is GMC a reliable car brand?
NHTSA complaint data shows reliability varies significantly by model and year within every major brand — including GMC. A brand-level reliability verdict is misleading because it averages a bad year of one model with a great year of another. VinItel's approach: pick your target GMC model + year and view that specific page for actionable reliability data. See vinitel.com/stats/nhtsa-complaints/gmc to browse all 18 GMC models.
Should I buy a used GMC?
Buying used requires two checks: (1) research the specific model + year for known problems using the NHTSA data on this page, and (2) run a VIN report on the exact car to check for hidden accidents, title issues, and odometer rollbacks. VinItel offers both — reliability research is free, individual VIN reports are $4.99 (vs. Carfax $44.99). Common GMC issues to ask about during inspection include engine problems.
