How to read this. Complaints are unverified reports owners file with NHTSA’s Office of Defects Investigation, counted once per case number. Raw totals are not adjusted for sales volume, and recent model years have had less time on the road. “Most complained” flags years well above the model’s median; treat it as a signal for deeper research, not a verdict.
