What the complaints were about
- use — 9.6% of this year's complaints, against 2.8% across the model's other years (3.4×). Owners wrote it as: use, signals, led, got off.
- less than — 7.2% of this year's complaints, against 2.2% across the model's other years (3.2×). Owners wrote it as: less than, vehicle less, occasional, occasional grinding.
Words owners used for the same problem are counted together, so a fault written four different ways is measured once. Grouped by which complaints they appear in, not by a list anyone wrote in advance.
Also unusual this year
- fan — 18% of complaints, 44× usual
- radiator — 16% of complaints, 40× usual
- steering assist — 15% of complaints, 38× usual
What owners wrote
Action Required "Steering Assist Warning" drive with caution, Temp gage reads cold, A/C stops working, engine cooling fan runs on high speed (even after the engine is shut off), pending P2018 code, with no Check Engine Light (CEL). Replaced Engine coolant Temp…
Radiator failure caused power steering assist to not function properly and insufficient vehicle heat function. Engine electric fan would run continuously after vehicle shutdown.

How this was worked out
Every year of the Chevrolet Blazer was compared against its own history rather than against other cars, which removes popularity and age from the answer — a common car draws more complaints at equal reliability, and an older one has had longer to accumulate them. A year is flagged when it drew at least 2.5× this model's median and at least 50 complaints.
This is a fault record, not a review. Nobody files a federal complaint to say the car was fine, so it shows what tends to go wrong — not whether owners liked it, and not whether it is a good car.
