Manufacturer file
What the Toyota records can tell us
The Toyota file currently stops at 12 nameplates: 4Runner, Camry, Corolla, Highlander, Prius, RAV4, Sequoia, Sienna, Tacoma, Tundra, Grand Highlander, Venza. Those 118 model-year entries contain 16,871 owner complaints. The missing denominator matters because these records do not say how many vehicles were on the road.
Unknown Or Other appears most often in the component tags, with 2,865 mentions. A single complaint may carry several tags. I use the total as a prompt to read that system's contract terms, not as odds that a repair will happen.
Across the same model years, NHTSA records show 451 recall campaigns and 22,259 manufacturer communications. Recall repairs are handled separately from a paid service contract, while communications include far more than defects.
