Are GMCs reliable?
Newer GMCs (Acadia, Canyon, Hummer EV Pickup, Hummer EV SUV, Savana, Sierra, Terrain, Yukon, and Yukon XL) do not share one complaint pattern. 4 of the 5 models average more owner complaints per year in the newer years than in the older years. Acadia averages fewer owner complaints per year in the newer years than in the older years. Hummer EV Pickup, Hummer EV SUV, Savana, and Sierra do not cover enough model years for that comparison.

Record by model
The table gives each model up to three years with the fewest complaints per year, and the year with the most, each counted from complaints filed in that year’s first 3 years on the road. A model year younger than 3 years is too early to compare, so it is left off that list. Recalls are a separate count. The numbers are for the US-market cars on this page. A model with more cars on the road produces more filings. How we count.
Complaints per year
Each bar is the median of the models with complaints on file for that year, not weighted by how many of those cars were sold. A year with no complaint file is left blank.
Recalls by model year
A campaign that covers more than one model is counted on each.
