Kestrel Take
A three-row family SUV that gets 35 mpg — the Highlander Hybrid pairs Toyota's durable hybrid system with a roomy, comfortable, AWD-available body, making it one of the most sensible family haulers on the market. It holds value strongly. A well-maintained Highlander Hybrid with a healthy hybrid battery is a superb, efficient, dependable people-mover; verify the hybrid system and enjoy the low running costs. The third row is tight, as always.
What we checked
Checked against public records, 2026-09-25
NHTSA holds 15 owner complaints for the 2021 Toyota Highlander Hybrid, and 4 recall campaigns.
That is too small a record to read a pattern from, so we are not going to pretend otherwise — with numbers this low one owner moves the percentage by a lot. What has been filed is grouped under airbags (8), the body and structure (4), electrics and electronics (1). Treat those as things to look at, not as the vehicle's known weaknesses. A thin file usually means few of these were sold or few owners filed. It is not evidence the vehicle is trouble-free, and the issues below are our own research rather than a reading of this record.
4 recall campaigns cover this model year. Recalls are repaired free, for any owner, with no time limit on most safety campaigns — but only if someone books it in. Ask the seller to show it was done, or have any dealer check the VIN; it takes them a couple of minutes and costs nothing.
Counts come from the NHTSA complaint and recall database — free, public, and worth checking yourself.
