2011 Chevrolet Aveo
This year drew an ordinary 77 complaints for a Chevrolet Aveo — the model's median is 169. What they were about is the unusual part: 16.9% of them mention pull, against 6.2% across the model's other years.
NHTSA opened a defect investigation into this model year.

What the complaints were about
- pull — 16.9% of this year's complaints, against 6.2% across the model's other years (2.7×). Owners wrote it as: pull, shut off, driving down, breaks.
- lost — 15.6% of this year's complaints, against 6% across the model's other years (2.6×). Owners wrote it as: lost, lost power, contact unable, coast.
- floor — 7.8% of this year's complaints, against 1.2% across the model's other years (6.4×). Owners wrote it as: floor, correctly.
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.

THE CONTACT WAS DRIVING APPROXIMATE 30 MPH WITH THE AIR CONDITIONER ACTIVATED WHEN A STRONG ODOR OF SULFUR EMITTED THROUGH THE AIR VENTS. WHILE PARKING, THE BRAKE PEDAL TRAVELED TO THE FLOOR AND A BURNING SMELL CIRCULATED INSIDE OF THE VEHICLE. THERE WAS NO WA…

How this was worked out
Every year of the Chevrolet Aveo 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.
