Our Mission

PlainCars exists because every car buyer, owner, and family deserves transparent, free access to the safety record of any vehicle on the road. The National Highway Traffic Safety Administration collects an enormous amount of safety data — consumer complaints, recall campaigns, crash test ratings, defect investigations — but navigating that data across multiple government portals is difficult and time-consuming. We believe that barrier should not exist.

Our mission is to make NHTSA safety data genuinely useful for everyday decisions. Whether you are evaluating a used car before purchase, checking whether your vehicle has an open recall, or trying to understand whether the problem you are experiencing with your brakes has been reported by other owners, PlainCars puts that information within reach in seconds.

We are not a paid review site and we do not accept manufacturer sponsorship. We do not assign our own reliability scores or editorial ratings. The data speaks for itself — our job is to present it clearly and let you draw your own conclusions.

Why Complaint and Recall Data Matters

Vehicle safety complaints are one of the few sources of ground-truth data about how cars perform in real-world conditions. Crash test ratings tell you how a vehicle performs in a controlled laboratory collision. Complaint data tells you what actually goes wrong after years on the road: transmissions that fail at 60,000 miles, electrical systems that cause fires, airbags that deploy without warning.

This data is especially valuable for used car buyers. A vehicle that earned five stars in crash testing may still have a troubling pattern of engine failures or brake defects in certain model years. Complaint data reveals these patterns in a way that marketing materials and dealership sales pitches never will.

Recall data matters because open recalls affect millions of vehicles on the road at any given time. NHTSA estimates that roughly 25 percent of recalled vehicles never get repaired. If you own or are considering purchasing a vehicle with an unresolved safety recall, you need to know — and you need to know what the defect is, how serious it is, and what the remedy looks like.

Data Sources

PlainCars aggregates data exclusively from official United States government sources. We do not use third-party estimates, proprietary datasets, or user-generated reviews.

• NHTSA ODI Complaints Database — Consumer-submitted vehicle safety complaints collected by NHTSA's Office of Defects Investigation. Each complaint includes the vehicle make, model, year, component category, narrative description, and flags for crashes, fires, injuries, and fatalities. The database contains over two million records spanning decades of vehicle production.
• NHTSA Recall Campaigns — Official safety recall data published through the NHTSA Recalls API. Includes campaign number, affected vehicles, defect description, consequence, and remedy for every recall issued in the United States.
• NCAP Safety Ratings — Crash test star ratings from NHTSA's New Car Assessment Program, covering frontal crash, side crash, and rollover resistance tests. These are the official government safety ratings for new vehicles sold in the U.S.
• NHTSA Investigations — Records of Preliminary Evaluations (PE) and Engineering Analyses (EA) opened by NHTSA's Office of Defects Investigation when complaint patterns suggest a potential safety defect.
• Bureau of Labor Statistics — Selected repair cost and automotive service data from BLS surveys, used to provide context on the economic impact of common vehicle defects.

Methodology

PlainCars processes three primary NHTSA datasets: consumer complaints (ODI), official recall campaigns, and NCAP crash test star ratings. The complaint database alone contains over two million records. We load all of this into a structured database and build model-level profiles that show complaint trends, component failure patterns, and recall history in one place.

Complaint tallies, crash counts, fire counts, and injury figures are presented exactly as consumers reported them to NHTSA. We do not adjust these numbers, apply statistical smoothing, or assign our own reliability or safety scores. When browsing a vehicle on PlainCars, the numbers you see are direct aggregations of the underlying NHTSA records.

Component categories (brakes, engine, electrical system, airbags, etc.) follow NHTSA's own standardized classification system. When a consumer files a complaint, they select from NHTSA's component list — we use the same categories to organize and present the data.

Vehicle make and model groupings follow NHTSA's naming conventions. In some cases, manufacturers change model names or rebrand vehicles across generations. We follow NHTSA's classification, which means a model's complaint history may span name changes if NHTSA groups them together.

Aggregate statistics (such as "most complained-about component" or "top affected models") are computed from the raw complaint records using straightforward counts and rankings. No weighting, scoring algorithms, or proprietary formulas are applied.

Data Currency and Update Schedule

The PlainCars database is rebuilt periodically from the latest NHTSA data exports. Our current dataset covers complaints and recalls from the early 1990s through 2025, encompassing over two million individual complaint records and tens of thousands of recall campaigns.

NHTSA publishes new complaints and recalls on a rolling basis. We pull updated data from NHTSA's public APIs and bulk data exports and rebuild the PlainCars database to incorporate new records. The typical update cycle is monthly, though we may update more frequently when a major recall campaign or safety investigation generates significant new data.

NCAP crash test ratings are updated as NHTSA publishes results for new model year vehicles, typically in the fall of each year as new models become available for testing.

If you notice data that appears outdated or incorrect, please contact us at hello@plaincars.com and we will investigate.

Editorial Independence & How Content Is Produced

The data on PlainCars is read directly from official NHTSA datasets — consumer complaints, recall campaigns, defect investigations, and NCAP crash-test ratings — and rendered into readable vehicle profiles by a documented, continuous editorial pipeline. No complaint tally, recall count, or star rating is typed in or edited by hand. The PlainCars editorial team, operating under Kiznis Studio, sets the standards a pipeline cannot: which datasets to use, how each metric is defined and labeled, the methodology, and the corrections process.

We do not accept payment, sponsorship, or promoted placement from any manufacturer or dealer. Our only revenue source is contextual display advertising served by Google AdSense — advertisers do not influence which vehicles we cover or how we present data, and they do not receive preferential placement.

Limitations and Disclaimers

NHTSA complaint data is a valuable safety resource, but it has inherent limitations that users should understand before drawing conclusions.

Complaints are self-reported. Anyone can file an NHTSA complaint. Complaints are not verified, investigated individually, or confirmed as defects unless NHTSA opens a formal investigation. A complaint describes what a consumer experienced — it does not prove that a defect exists or that the vehicle manufacturer is at fault.

Complaint volume does not equal defect rate. A vehicle with 500 complaints is not necessarily less reliable than one with 50. Sales volume, owner demographics, media coverage, and even the ease of the filing process all influence how many complaints a vehicle accumulates. Popular vehicles naturally generate more complaints in absolute terms.

Reporting bias exists. Owners who experience problems are far more likely to file complaints than owners with trouble-free vehicles. The database captures the negative tail of the ownership experience — it does not represent overall satisfaction or reliability.

Not all safety issues appear in complaints. Some defects are discovered through manufacturer testing, dealer service records, or NHTSA's own monitoring before consumers file complaints. The absence of complaints about a specific issue does not guarantee the issue does not exist.

Data may be incomplete. While we strive to include every record published by NHTSA, processing errors, API changes, or timing differences between our update cycle and NHTSA's publication schedule may result in temporary gaps. Always verify critical safety decisions with the official NHTSA database at nhtsa.gov.

PlainCars is not affiliated with NHTSA, the U.S. Department of Transportation, or any vehicle manufacturer. This site is for informational purposes only and should not be used as the sole basis for vehicle purchase decisions, legal claims, or safety assessments. Always consult qualified professionals for safety-critical decisions.

How Content Is Produced

Data pages — complaint tallies, recall summaries, model profiles, crash ratings — are generated directly from official NHTSA sources (the ODI complaints database, the Recalls API, and NCAP ratings) by a continuous editorial pipeline, with no hand-entry of the underlying numbers. Guides, methodology, and explainer pages like this one are written from that source data following our documented editorial standards. When a reader reports an error, we verify it against the NHTSA record and, if it is ours, fix it at the data layer so every affected page is corrected at once — the full process is set out in our editorial & corrections policy.
