NHTSA campaign numbers encode the year they were issued, so the gap to the model year can be measured. Sorted by component, the spread is enormous.
| Component | Average lag | Share taking 10+ years |
|---|---|---|
| Airbag inflators | 9.23 yrs | 41.4% |
| Airbags (all) | 6.86 yrs | 29.2% |
| Exterior lighting | 6.58 yrs | 28.2% |
| Fuel system | 4.80 yrs | 15.9% |
| Service brakes | 2.18 yrs | |
| Reversing cameras | 2.18 yrs | |
| Tyres | 1.61 yrs | Fastest |
Nearly six times the difference
A tyre defect surfaces in 1.61 years. An airbag inflator defect takes 9.23 — and 41.4% of inflator campaigns are announced a decade or more after the car was built.
The pattern is not random. It separates parts that fail suddenly from parts that degrade.
Fast failures announce themselves
Tyres, brakes and reversing cameras are all caught in about two years, and they have something in common: when they go wrong, the driver notices immediately. A brake that pulls, a camera that shows a black screen, a tyre that fails — these produce complaints within weeks, and complaints are what start an investigation.
Electrical faults sit in the same group at 2.66 years, for the same reason. Something stops working and the owner reports it.
Slow failures hide behind chemistry
The inflator is the extreme case, and it explains itself once you know what fails. The propellant degrades over years of heat and humidity cycles. A ten-year-old inflator in Florida is a different object from the one that left the factory, and nothing about the car indicates it. There is no warning light for a degrading chemical charge.
Exterior lighting at 6.58 years works similarly — housings crack, seals let moisture in, corrosion spreads. Gradual, unremarkable, and invisible until enough units have failed to form a pattern.
What this means for a used buyer
The slowest components are the safety-critical ones. Brakes and tyres get caught fast. Airbags — the part that only matters once, at the worst possible moment — take four times longer.
An old car is not finished collecting recalls. If 41% of inflator campaigns land a decade out, a fifteen-year-old car can still acquire new ones. We measured the overall pattern in a third of recalls arrive five years late.
Inflators are still the most common open campaign in the wild. When we looked at cars our own readers own, a passenger-side inflator was the single most frequent unrepaired recall — found on 33 of 105 vehicles.
Check by VIN, not by memory. The repair is free at any age. A VIN check lists the open campaigns for a specific car, and given the lag figures, it's worth repeating on a car you already own. We covered how the recall mix itself changed over time in cars used to get recalled for headlights, now it's cameras.
Frequently asked questions
Which car defects take longest to be recalled?
Airbag inflators, averaging 9.23 years from model year to campaign, with 41.4% announced a decade or more later. Airbags generally take 6.86 years and exterior lighting 6.58.
Which recalls happen fastest?
Tyres at 1.61 years, then brakes and reversing cameras at 2.18, and electrical faults at 2.66. These are components whose failure the driver notices immediately, which generates the complaints that start an investigation.
Why do airbag inflator recalls take so long?
The propellant degrades gradually with heat and humidity cycles rather than failing suddenly. There's no warning light for a deteriorating chemical charge, so the defect only becomes visible once enough units have failed.
Can an old car still get new recalls?
Yes. With 41% of inflator campaigns announced ten or more years after the model year, a fifteen-year-old vehicle can still acquire new ones — and the repair remains free regardless of the car's age.

Tesla Fixes 74% of Its Recalls Overnight. Kia Fixes 31% That Way.
Two cars can have the same number of recalls and completely different consequences for the owner. The difference is whether the fix requires a workshop or a download.
A Clean Recall Check Today Means Nothing. A Third of Recalls Arrive Five Years Late.
Recall numbers carry a hidden date stamp. I used it to measure how long a defect stays undiscovered — and the answer changes what a clean report is actually worth.
