What the complaints were about

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

What owners wrote

FUEL GAUGE FAILURE, INACCURATE READING. FUEL GUAGE STAYS ON EMPTY. DRIVER HAS TO RELY ON TRIPOMETER TO GUESS RANGE TO DETERMINE WHEN TO FILL GAS TANK.
FUEL GAUGE READS EMPTY WHEN THE TANK IS HALF FULL OR LESS. IT REGISTERS LOW FUEL. I HAD TO REPLACE THE SENDER FLOAT ASSEMBLY TO FIX. GM DEALERSHIP SAID IT WAS NOT COVERED BY A RECALL AND IT WAS OUT OF WARRENTY DUE TO MILAGE.

Verbatim from NHTSA complaint filings, with identifying details removed.

How this was worked out

Every year of the Chevrolet Trailblazer 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.
