How to Report a Vehicle Safety Problem to NHTSA
Filing a safety complaint takes about 10 minutes. Here is what to have ready, what happens after you hit submit, and why one report can matter.
To report a vehicle safety problem, file a complaint with the National Highway Traffic Safety Administration at nhtsa.gov/report-a-safety-problem, or call the Vehicle Safety Hotline at 888-327-4236. Have your VIN, the mileage and a clear description of what happened. NHTSA reviews every complaint and uses them to decide which defects to investigate.
A complaint is free and takes about 10 minutes online. It is the main way owners feed the federal recall system, and it is separate from any complaint you make to the dealer or the automaker.
What counts as a safety problem?
A safety problem is a defect that raises the risk of a crash, injury or fire. Examples include brakes that fade or fail, steering that locks or pulls suddenly, airbags that deploy without a crash or fail to deploy in one, loss of power at speed, fuel leaks, smoke or burning smells, and seat belts that do not latch. Problems with tires, car seats and equipment such as aftermarket lights can be reported through the same system.
Comfort and quality issues such as squeaks, paint flaws or a weak air conditioner are not safety defects. For those, the dealer, the automaker and your state’s lemon law are the right routes.
How do I file a complaint online?
The online form on NHTSA’s report a safety problem page walks you through each section. The steps are:
- Choose the product type: vehicle, tire, car seat or equipment.
- Enter the 17-character VIN. It fills in the make, model and year and lets NHTSA match your report to recalls and investigations.
- Pick the components involved, such as brakes, steering or air bags. Choose every one that applies.
- Give the date of the incident, the mileage, the speed if known, and whether there was a crash, fire, injury or death.
- Describe what happened in plain words: what you were doing, what the car did, any warning lights, and what the dealer found.
- Decide whether to share your name, contact details and VIN with the manufacturer. This is optional.
- Submit and keep the confirmation number.
Facts help more than adjectives. “At 45 mph the brake pedal sank to the floor and the ABS light came on” is more useful than “the brakes are terrible.” If a shop inspected the car, mention what it found and keep the invoice.
Can I report by phone or mail?
Yes. The Vehicle Safety Hotline at 888-327-4236 takes complaints in English and Spanish. NHTSA lists its TTY line as 888-275-9171. You can also write to NHTSA by mail, but the online form is faster and puts the report into the database without retyping.
What happens after I file?
Your complaint goes into NHTSA’s public complaint database after personal information is removed, and staff in the Office of Defects Investigation review it. NHTSA says it analyzes complaints continuously for trends, together with manufacturer data on warranty claims, injuries and field reports.
Several things can follow:
- Nothing visible, if the report does not match a pattern. It stays in the database and can count later if more reports arrive.
- A call or email from NHTSA staff asking for photos, receipts or more detail. Not every complainant is contacted.
- A question to the manufacturer, which sometimes leads to a recall without a formal case.
- A formal investigation, starting with a preliminary evaluation.
If you agreed to share your details, the manufacturer may also contact you. NHTSA does not represent you in a dispute with the automaker and does not arrange repairs for individual owners.
How do complaints turn into recalls?
Complaints become recalls when they show a pattern that points to a defect. There is no fixed number of reports that triggers action. NHTSA says a single complaint can be enough when the risk is serious, while a common but minor issue may never qualify.
When ODI sees a trend, it can open a preliminary evaluation and request data from the automaker. Many cases end with the automaker recalling the vehicles on its own. Our explainer on NHTSA investigation stages covers what PE, EA and RQ mean and how long each step is meant to take.
If a recall follows, the repair is free at a franchised dealer. You can check whether one already covers your car with our guide to checking recalls by VIN.
Should I also tell the dealer and the automaker?
Yes. A complaint to NHTSA does not open a warranty claim or schedule a repair. Tell the dealer in writing, ask for a copy of the repair order even if they find nothing, and open a case with the automaker’s customer line. Those records matter if the problem returns, if a recall later reimburses earlier repairs, or if you end up using your state’s lemon law.
Bottom line
If your car did something dangerous, file the NHTSA complaint the same week while details are fresh. Include the VIN and the facts, keep your repair paperwork, and check your VIN for recalls every few months.
FAQ
Is my NHTSA complaint public?
The text of the complaint is published in NHTSA’s database with your name and contact details removed. Anyone can search complaints by make, model and year on nhtsa.gov.
Does filing a complaint cost anything?
No. Filing online or through the hotline is free, and you do not need a lawyer or a mechanic’s statement to submit one.
Can I file a complaint about a car I no longer own?
Yes. The report is about the vehicle and the incident, not current ownership. Include the VIN if you still have it, since it lets NHTSA match the report to the right build.
Will NHTSA tell me what happened with my complaint?
Usually not individually. You can follow any resulting investigation or recall by checking your vehicle on nhtsa.gov, where case documents and recall notices are posted.
