73,099 Americans Reported a Defect to NHTSA Last Year. The Agency Investigated 33.

NHTSA publishes its Office of Defects Investigation quarterly metrics with the enthusiasm of a student turning in homework they copied from the back of the textbook. The FY2025 numbers arrived without commentary, which was probably wise: 73,099 Vehicle Owner Questionnaires went in and 33 investigations came out, a conversion rate of 0.045%, one investigation for every 2,215 complaints filed.^[1]

Quarterly complaint volume climbed 26% through the fiscal year, from 16,055 VOQs in Q1 to 20,196 in Q4, while investigation counts bumped along at 10, 8, 5, and 10.^[1] Americans are reporting more defects than they did twelve months ago, and the number of investigations opened in response has not moved at all, which is another way of saying the agency's intake capacity is fixed while the signal it receives is accelerating.

Follow the pipeline downstream and the picture curdles. Those 33 investigations sat alongside 992 recall campaigns covering 30.78 million vehicles in FY2025, but crediting NHTSA with that output would be generous, since the overwhelming majority of those recalls were manufacturer-initiated rather than compelled by federal investigation.^[1] NHTSA's own recall completion research puts the weighted average fix rate for campaigns initiated between 2012 and 2022 at 65.8%, meaning roughly 10.5 million vehicles recalled in FY2025 alone will statistically never be repaired.^[2]

Ford illustrates how these failures compound in the real world. The automaker leads all manufacturers in recall volume for 2026, including a single February campaign affecting 4.3 million vehicles with faulty trailer brake systems, and is currently re-recalling 387,000 vehicles across the Focus, Fusion, Mustang, Escape, and F-150 lines because the original recall repair was itself defective.^[3][4] Stellantis told 1.08 million Jeep Wrangler and Gladiator owners this month to park outside and away from structures because their power steering wiring can start fires even with the ignition off, a defect that complaints had been flagging since 2023.^[5]

NHTSA would argue that low investigation counts prove the system is working as designed, since manufacturers are self-policing and catching their own defects before federal intervention is necessary, and that argument holds right up until the manufacturer-initiated fix turns out to be wrong, which is exactly what Ford's re-recall demonstrates. VOQs include duplicates, user-error reports, and complaints about existing recalls, so 73,099 overstates the genuine discovery count, and a single investigation can cascade into a multi-million-vehicle recall, which means raw counts understate real-world impact. Neither caveat explains why the conversion rate has remained flat while submissions surged 26% in twelve months.

File your complaint at nhtsa.gov/report-a-safety-problem anyway, because VOQ volume is one of the few inputs the agency uses to decide where to look next, and the 26% increase in FY2025 suggests Americans are figuring that out. Check your VIN at nhtsa.gov/recalls quarterly rather than waiting for a letter that, given the completion rate data, may never arrive. If NHTSA has not recalled your vehicle, understand what that actually means: your complaint joined a pile of 73,098 others, and the agency picked 33.
