How to Read NHTSA Complaint Data Without Being Misled
Published October 10, 2026
Owner complaints are the most human part of the federal vehicle-safety record: thousands of drivers describing, in their own words, what went wrong. They are also the easiest part to misread. A model with 700 complaints is not automatically worse than one with 70. This guide explains where the data comes from, what each field means, and how to tell a real pattern from noise.
Where complaints come from
Anyone can report a vehicle safety problem to NHTSA’s Office of Defects Investigation (ODI), online at nhtsa.gov/report-a-safety-problem or through the Vehicle Safety Hotline. Each report gets an ODI number and is published with personal details removed. NHTSA does not check each report before it appears. What it does is read them in bulk, looking for several owners describing the same failure.
Our index holds 285,780 of these complaints across the vehicles we cover. 4.4% of them say a crash happened and 1.3% report a fire. Most describe a failure that did not end in either, which is exactly why they are useful: they show problems before they become collisions.
What each field means
| Field | What it tells you |
|---|---|
| Component | The system the owner chose, such as engine, air bags or steering. The owner picks it, so similar problems can land in different categories. |
| Crash / fire | Whether the owner reports that the problem led to a crash or a fire. |
| Injuries / deaths | As reported by the person filing. Not confirmed by NHTSA. |
| Incident and filing dates | When it happened and when it was reported. A long gap is common after a recall makes the news. |
| Summary | The owner’s description. This is where the real information is. |
Four ways complaint counts mislead
- Sales volume. Counts are raw, not per vehicle sold. A pickup that sells hundreds of thousands a year will out-collect a niche sports car even if it fails less often. The counts on this site are raw NHTSA counts, and we label them that way.
- Age. A model year that has been on the road for ten years has had ten years to collect complaints. A new one has had a few months.
- News. A recall announcement or a widely shared video sends owners to NHTSA, so complaints arrive in bursts. A spike can reflect attention rather than a new problem.
- Unverified detail. A single report can be mistaken, describe normal behaviour, or be a duplicate. One complaint is an anecdote.
How to find a real pattern
Read past the totals and look for repetition. The signals that matter are:
- Many owners naming the same component and describing the same symptom, such as a transmission that slips at the same speed or an air bag light that will not clear.
- The same complaint across several model years of one model, which suggests a shared part.
- Complaints that mention a crash, fire or injury, which NHTSA treats as the most serious.
- A matching NHTSA investigation or recall. If a recall already covers the problem, check whether the vehicle’s repair has been done.
When you are looking at a used car, a pattern of complaints on a part that has not been recalled is a question for the seller and for your mechanic: has it been replaced, and is there a receipt?
How we present complaints
Each vehicle’s complaint page shows the total from NHTSA, the most-reported components, and the crash and fire counts, followed by recent owner reports in full. We do not rank vehicles by complaint count or turn the counts into a score, because without sales figures that would suggest a precision the data does not have. Our methodology explains the rest.

Browse complaintsFrequently Asked Questions
Does NHTSA verify owner complaints?
No. A complaint is the owner's own account. NHTSA reviews complaints to look for patterns that may point to a safety defect, but it does not confirm the facts of each report before publishing it.
Does a high complaint count mean a car is unreliable?
Not on its own. Counts are not adjusted for how many vehicles were sold, so a best-selling model collects more complaints than a rare one with the same defect rate. Look at what the complaints describe and whether they cluster on one part.
Can complaints lead to a recall?
Yes. Complaints are one of the main inputs NHTSA's Office of Defects Investigation uses to decide whether to open an investigation, and an investigation can end with the manufacturer recalling the vehicle.
How do I file a complaint?
At nhtsa.gov/report-a-safety-problem, or by calling the Vehicle Safety Hotline at 1-888-327-4236. A complaint sent to Verify the Vehicle does not reach NHTSA.
