of the campaign

The final figure: the six quarters of reporting that 49 cfr 573.7 requires have closed.

This is the manufacturer's own cumulative count of vehicles it has inspected and repaired, divided by the vehicles the campaign covers. It files that count with NHTSA every quarter for six consecutive quarters, starting from the quarter in which owners were told a remedy was ready, and then the obligation ends — so a figure on an older campaign is where the count stopped, not where it stands today.

It rarely reaches 100%, and not because the work was not done. The same report asks manufacturers to count vehicles they could not reach at all — exported, stolen, scrapped, or simply never located — and those stay in the denominator. A low number means a lot of these vehicles are still out there unrepaired; it does not tell you which ones.

Check one specific vehicle

A recall applies to a build range, so year, make and model cannot settle it. NHTSA checks a VIN against the manufacturer's own list and tells you whether the repair is still outstanding on that vehicle.

Common questions

Source: NHTSA, 49 CFR Part 573

Does this recall repair cost anything?

No. Federal law requires the manufacturer to remedy a safety defect or a compliance failure at no charge, for vehicles up to 15 years old measured from the date of first sale. A dealer that asks you to pay for a recall repair is in the wrong.

How do I know whether my vehicle is included?

By VIN, not by model year. The manufacturer files a build range with NHTSA and only vehicles inside it are covered, so two identical-looking cars from the same year can differ. NHTSA's own lookup checks a VIN against the manufacturer's list.

What if the repair is not available yet?

It happens, and often. Manufacturers must notify owners when a defect is found even if the parts or the software are not ready, then notify them a second time once the remedy exists. The remedy filed for this campaign is described above.

What did the manufacturer say was wrong?

The problem, risk and fix quoted on this page are the manufacturer's own words as filed with NHTSA under 49 CFR Part 573. WhichTrim does not paraphrase them.

Who started this recall?

NHTSA's record credits the manufacturer. A recall can begin with the manufacturer's own testing, with a defect investigation, or with a compliance test against a Federal Motor Vehicle Safety Standard.
