specific things to inspect and negotiate

What goes wrong

Federal complaint volume on the 8-speed automatic in these is genuinely high, hesitation, harsh low-speed shifts, clunky engagement. Toyota issued software updates; most live with it fine, a minority escalate to hardware. On the Sienna this applies to 2017-2020 (the 2021+ is a hybrid with a different transmission), and on the RAV4 to 2019+.

Federal record for the 2020 Toyota Highlander, pulled from NHTSA when this page was built:
304 owner complaints on file , most-reported: POWER TRAIN (119) · AIR BAGS (32) · UNKNOWN OR OTHER (31).
4 safety recalls listed.
Complaint volume tracks how many were sold as well as how they held up , read it as a pattern, not a score. Counts change; confirm live at nhtsa.gov or by running the free check below.
Rough cost: $0 for software fixes · $4,000+ in the minority that need hardware. Broad estimates , labor rates and parts vary widely by region and shop.

What to do about it

Before you hand over cash: Cold test drive, first 10 minutes: light throttle from stops, watch for lag-then-clunk into second, and hesitation pulling into traffic. Confirm software updates were done at a dealer. Drives clean cold = it’s likely fine.

Whatever you find, a $100-150 pre-purchase inspection by an independent mechanic is the cheapest money you’ll spend on any used car , including this one.
