Many recalls begin with owners. When enough people report the same problem, the regulator can open an investigation, and an investigation can end in a recall. If something on your car fails in a way that could hurt someone, report it.
In the United States: NHTSA
Use NHTSA's "Report a Safety Problem" page. NHTSA says complaints go into a public database after personal details are removed, that similar reports about the same product can lead to an investigation, and that "complaints like yours help us investigate possible defects, which could lead to a safety recall".
In the United Kingdom: DVSA
The UK government's guidance is that you can report a serious safety defect with your vehicle or an accessory if it could cause injury; the route is on GOV.UK under vehicle recalls and faults. Check whether your car is already recalled first, at GOV.UK.
What to include
- The VIN, make, model and year.
- What happened, when, and at what speed or in what conditions.
- Whether anyone was hurt, and any crash or fire.
- Photos, repair invoices and the dealer's findings.
- Whether the problem happened more than once.
Before you report: is it already recalled?
Check the car by VIN first: our VIN check looks at the US, Canadian, UK and other registers. If a recall already covers it, follow what to do about a recall; the repair is free.
What happens next
A single complaint rarely starts a recall on its own. Investigators look for patterns across many reports, and makers can also decide to recall after their own reviews. Our study pages show how long a defect hides before it is recalled.
