Every complaint in the federal database carries two dates: the day the car failed, and the day somebody reported it. Across 1,075,924 records that carry both, the average gap is 229 days.
We have looked at that gap by component before, and it varies by what broke. It varies far more by what happened to the people in the car — and in the opposite direction to the obvious one.
| What happened | Average delay before filing |
|---|---|
| Someone died | 467 days |
| All complaints | 229 days |
| The car caught fire | 179 days |
A fatal outcome more than doubles the time it takes for the complaint to arrive.
Severity does not produce urgency
The intuitive model is that a frightening event gets reported immediately. It does not survive contact with the data.
A fatal incident starts a sequence that has nothing to do with vehicle safety regulation: police attend, an insurer opens a claim, sometimes lawyers become involved, and a family deals with all of it in an order that has nothing to do with paperwork. Filing a defect report is the last thing anybody does, and it is often done by a relative rather than the person who was driving.
A fire behaves in the opposite way. The car is gone, the insurance claim requires documentation immediately, and there is nothing left to postpone. Those complaints arrive fifty days faster than average.
The practical consequence is uncomfortable: the most serious evidence about a defect reaches the regulator last. A pattern that would be obvious from ten fatal incidents is, at any given moment, missing the ones from the past year.
The whole record has been speeding up
The 229-day average hides a long trend. Grouped by the decade the complaint was filed in, the delay has been falling steadily.
| Filed in | Average delay | Complaints |
|---|---|---|
| 1990s | 196 days | 57,094 |
| 2000s | 318 days | 217,539 |
| 2010s | 240 days | 465,978 |
| 2020s | 160 days | 335,310 |
The 2000s are the outlier. That decade absorbed a backlog: complaints about older vehicles arriving years late, as the online filing route opened and people reported things that had happened long before.
Since then the delay has halved. Two things drove it. Filing moved from paper to a web form, and recalls became news — a driver who reads a headline about their own model now has a reason to go looking for somewhere to report.
Most complaints are not filed quickly at all
Averages hide the shape. The distribution is heavily split between people who report immediately and people who report years later.
| Filed within | Complaints | Share |
|---|---|---|
| The same day | 139,253 | 13% |
| A week | 273,553 | 25% |
| A month | 198,823 | 18% |
| More than five years | 16,089 | 1.5% |
Only one complaint in eight is filed on the day the car failed. At the other end, 16,089 describe something that happened more than five years earlier.
What this changes when you check a car
Any complaint database, including ours, reports the past rather than the present. On average it is seven months behind, and for fatal cases more than a year.
That makes a clean complaint record on a recent model year close to meaningless — not because the model is fine, but because nobody has finished reporting yet. Recalls do not have this problem: they are dated when issued. Check the open recalls against the VIN, and treat the complaint count on a car built in the last two years as provisional.
Frequently asked questions
Why do fatal incidents take longer to report than other complaints?
Complaints involving a death average 467 days between incident and filing, against 229 overall. A fatal incident triggers police reports, insurance claims and sometimes litigation, none of which involve the safety database. The defect report is usually filed last, often by a relative rather than the driver.
Why are fires reported faster than average?
They arrive in 179 days against an average of 229. When a car is destroyed the insurance process starts at once and there is nothing left to postpone, so the report follows quickly.
Has reporting got faster over time?
Yes. Complaints filed in the 2000s averaged 318 days behind the incident; those filed in the 2020s average 160. Online filing replaced paper, and recall coverage in the news gives owners a reason to look for somewhere to report.
