2019 Mazda CX-9
This year drew an ordinary 52 complaints for a Mazda CX-9 — the model's median is 68. What they were about is the unusual part: 40.4% of them mention overheating, against 10.3% across the model's other years.
NHTSA opened a defect investigation into this model year.

What the complaints were about
- overheating — 40.4% of this year's complaints, against 10.3% across the model's other years (3.9×). Owners wrote it as: overheating, developed, damage, entire.

- may — 19.2% of this year's complaints, against 5.6% across the model's other years (3.5×).
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.

How this was worked out
Every year of the Mazda CX-9 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.
