How we score each year

We compare each year of the Chevrolet TrailBlazer to the model's own typical numbers, not to other cars. A year reads solid when its recalls, owner complaints, and federal investigations sit at or below what is typical for this model, mixed when some of those numbers run above typical, and avoid when they run far above it. Deaths, reported fires, and an NHTSA advisory to park outside count against a year no matter what this model's baseline looks like.

A year is scored only when NHTSA has both complaint and recall counts for it. Complaint data often lags for the newest years, so a recent year can read not enough data even while its recall count already shows in the table. When the history is too thin, we say not enough data instead of guessing. Service bulletins are routine maintenance guidance from the manufacturer and do not lower a year's score.

Scores run 0 to 100, higher is better. Recall, complaint, and investigation figures come from NHTSA records. Fuel economy, fuel cost, and horsepower figures come from the EPA, shown as the median across the year's trims.
