How we count
Counts are unique owner complaints (by NHTSA ODI number) filed with NHTSA for each Toyota 4Runner model year, from NHTSA's public complaints data fetched July 2026 to November 2026. A complaint counts as a transmission complaint when NHTSA's component list for it includes Power Train (transmission, transfer case and driveline).
Per 1,000 sold divides complaints by published U.S. calendar-year sales for that year. A year needs at least 5,000 sales to get a rate, and a model needs at least 3 such years for its overall rate. The comparison median covers every model with at least 50 transmission complaints that clears those floors.
These are complaint rates, not failure rates. Owners report some problems more than others, and a complaint is not a confirmed defect.
