Vehicles With the Most Fuel System Complaints

These model years have the highest number of fuel system complaints filed with NHTSA since 1995, ranked by report volume.

How this ranking is computed

Counts come directly from NHTSA Office of Defects Investigation records, aggregated per vehicle as described on our methodology page. Complaint counts are not normalized by sales volume — high-selling vehicles naturally accumulate more reports.

Based on NHTSA ODI data through June 2026. Complaints are consumer-reported and unverified. Updated July 5, 2026.
