2021 Toyota Highlander: engine and transmission complaints
HIGH COMPLAINT SIGNAL
59%
272 of 459 relevant owner complaints are about the engine, transmission or fuel system
59% of relevant owner complaints filed with NHTSA on the 2021 Toyota Highlander are about the engine, transmission or fuel system. That is a model-level pattern, not bad luck.
Worse than 79% of the 1,230 model years we track (2010–2023).
Excludes 49 airbag, lighting and seat-belt recall complaints that would otherwise mask the signal (unadjusted: 54%).
Looking at a specific Highlander?Check its VIN: the full report, quotes about its own engine, and whether its recalls are still open. First report free.
The percentage is each model year's drivetrain complaint share. No elevated signal describes the model year, not any one car; a well-kept example of a flagged model can still be the right buy, and any of these still needs an inspection.

This does not say whether a particular car has an open, unrepaired recall. That depends on the VIN.
Before you buy a 2021 Toyota Highlander
Ask the seller whether the transmission has ever been repaired or replaced, and whether the car has shown shuddering, slipping, delayed or harsh shifts, or a whine at speed.
Drive it from a cold start and long enough to warm up. Many transmission faults hide once the car is warm.
Get an independent pre-purchase inspection from a mechanic you choose, and tell them to focus on the transmission.
4 recall campaigns on this model year. Whether a specific car still has one open depends on the VIN; the report checks that.
Ask for service records. A transmission already replaced under warranty is a different car from one that was not.
Have the VIN?Paste it and get the full report for that car. First report free, then a 30-day pass covers a whole car search.
