The best and worst Chevrolet Blazer years, by the numbers
Short answer: among Chevrolet Blazers old enough to judge (2019–2022), the 2022 has the fewest owner complaints per 10,000 sold. The 2019 has the most.
We counted every owner complaint filed with the federal government (NHTSA) for each model year and divided by how many were sold that year, so a year that sold more doesn’t look worse just for being popular. Years newer than 2022 are shown but not ranked — they haven’t been on the road long enough. How this is calculated.
Years with the most complaints
2019 Chevrolet Blazer · 32.0 per 10,000 sold (1.6× this model’s typical year)
Most-reported: Transmission control module and sensors, typically around 36,500 miles; then body control and other modules.
Years with the fewest complaints
2022 Chevrolet Blazer · 7.3 per 10,000 sold (0.4× this model’s typical year)
Most-reported, even so: Cooling system: radiator, water pump, thermostat, fan, typically around 49,500 miles.
Every year: complaints per 10,000 sold
Typical Chevrolet Blazer year: 20.5 per 10,000 sold.
Complaints are counted once each, even when an owner lists several parts. Sales are US units sold in the calendar year, a close stand-in for the model year.
