The TOYOTASIENNA HYBRID appears in NHTSA's Office of Defects Investigation database with 323 consumer safety complaints and 5 recall campaigns across 6 model years (2021–2026). That averages roughly 54 complaints per model year. Report counts can differ between model years for many reasons; this dataset does not establish the cause of a difference.
Complaint volume on a nameplate alone is not a reliability verdict: a long-running bestseller can accumulate more filings than a low-volume niche model because more vehicles are on the road. The table below shows report counts and published NHTSA crash-test ratings side by side for each model year. The filing-year histogram shows the timing of submitted reports, not a causal trend.
NHTSA has 51 investigation files tied to this model, with 1 currently open. Investigation records, complaint reports, and recall campaigns each provide different context. Use the official NHTSA VIN lookup and the underlying notices to research a specific vehicle; PlainCars does not infer a vehicle-risk or pricing conclusion from these records.
Complaints by Year
Complaint Filing Trend
NHTSA complaint volume by year filed (not model year).
Filings moved from 10 in 2017-2021 to 313 in 2022-2026, a rise of 3030%. That is the 99th percentile of change across the 772 nameplates with enough filings in both windows to compare, where 0 is the steepest fall and 100 the steepest rise.
Filing volume, not a reliability verdict: counts also move with how many vehicles are on the road, how old they are, and whether a recall drew attention. Computed from this portal's NHTSA filing-year records over the same two windows the trend rankings use.
