Structural corrosion complaints by model year and where rust occurs
Reliability

Rust Complaints Fell 41%. The Ones Left Are Structural.

Bodywork corrosion largely stopped being the thing that kills cars. What replaced it is less visible and more expensive: rust in the places holding the suspension on.

1,930 Complaints Describe a Door Opening While Driving

A door latch is the least glamorous part of a car and one of the few whose failure has no intermediate state. It either holds or it does not, and the complaints describe what happens when it does not.

One Petrol System Complaint in 23 Involves a Fire

Fuel system faults sound uniformly alarming. Split by which part of the system failed and the risk separates cleanly into two groups — and only one of them is about fire.

Airbag complaint volume and injuries over three decades
Reliability

Airbag Complaints Carry 28,165 Injuries. Nothing Else Is Close.

The device that has saved more lives than any other addition to a car also generates the largest injury total in the complaint record. Both facts are true at once, and the second one has a specific cause.

Vehicle speed control complaints filed over three decades
Reliability

Sudden Acceleration Reports Tripled in 2010. Then They Faded.

Unintended acceleration is the most contested failure in motoring. The complaint record does not settle the argument, but it does show something clear: reports of it follow the news as much as they follow the cars.

Injury and property damage claim rates against vehicle curb weight
Reliability

Every 250kg Cuts Injury Claims by About 9%. Someone Pays.

The protective effect of mass is usually argued from anecdote. Put measured kerb weights against claim frequencies and it becomes a clean line — along with the cost, which lands on somebody else entirely.

Vehicles whose NHTSA crash rating dropped between consecutive model years
Reliability

25 Cars Lost a Crash Star Between Model Years

A car that scored five stars last year is assumed to score five this year. Usually true, and the exceptions are informative: they cluster in two specific tests and almost never in the third.

Even the Sticker Recalls Say "Risk of a Crash"

Some recalls sound trivial. A wrong number on a sticker, a missing line in the manual. We went looking for the harmless category and could not really find one, which says something about how the threshold works.

Rollover Stars Fall a Full Point for Every 50cm of Height

Of the three crash tests, one is not really a test of engineering at all. It is a measurement of shape, and you can predict the result from a tape measure before the vehicle reaches the track.

A Mirage Injures Its Driver 6x More Often Than an F-450

Crash ratings tell you how a car protects its own occupants in a standardised test. Insurance claim data tells you what actually happens on the road, to everybody involved — and those are two very different questions.

Death rate per thousand complaints by vehicle component
Reliability

Tyre Complaints Carry 15 Deaths per 1,000. Nothing Else Comes Close.

Complaint counts measure how often something annoys people. Weighted by outcome instead, the list reorders sharply — and the components at the top are not the ones that generate the most reports.

Average vehicle age when owner complaints are filed, by decade
Reliability

Cars Were 3.5 Years Old When Owners Complained. Now It's 6.4.

The regulator's complaint database is usually read as a reliability record. Read it by the age of the car instead and it turns into a record of who owns cars, for how long, and when they decide something is worth reporting.
