One of the years to avoid

With 31 complaints filed to NHTSA — about 2.7 times the median Denali year — the 2001 model ranks #2 of 14 Denali years for complaint volume. It lands on the years-to-avoid list.

No single system dominates the record — complaints spread across brakes (6), transmission (5), and fuel system (3), which usually points to general build quality rather than one defect.
