Chevrolet Blazer problems, by model year and system
810 complaints owners filed with NHTSA about the Chevrolet Blazer 2019–2027, and the 3 systems the record is deep on — electrical (240), engine (196), transmission and drivetrain (185). Each system has a page across the years; 5 model-year pages go deeper still. Every figure is a linked federal record; none is a failure rate or a verdict on one car.

Complaints owners filed with NHTSA naming each system, per model year; a bold count links the year’s own page on that system. Counts scale with sales and with time on the road; nothing here is a rate, and NHTSA’s headings are coarse (“Power Train” is the transmission and the driveline).
Common questions
Source: NHTSA complaint databaseWhich Chevrolet Blazer system draws the most complaints?
Electrical: 240 complaints across 9 model years, 30% of everything owners filed about the Chevrolet Blazer. A count, not a rate — it says nothing about how many were sold.
Which Chevrolet Blazer year has the most complaints?
2020 (219), 2019 (186), 2021 (134). Older years have had longer to collect them; the year pages show each year's share by system.
