NHTSA 5-Star Safety Rating
Powertrain complaints dominate what owners report about the 2020 Highlander, making up the largest share of filed complaints by a wide margin. Transmission failures are the central theme, owners describe internal failures requiring full transmission replacement, often with no warning lights beforehand. Common symptoms include whining or grinding noises during acceleration, metal debris found in transmission fluid, and in some cases the vehicle becoming unable to move and requiring a tow. Airbag-related complaints are the second most reported system, though the representative narratives don't elaborate on specific airbag symptoms beyond the filing. Service brake complaints, particularly on hybrid trims, include a periodic surging or slipping sensation during braking that owners describe as inconsistent and hard to reproduce.

By System
The 2020 Toyota Highlander has 7 recalls, the most serious being an engine stop-start system fault that can stall the engine without warning while driving, raising the risk of a crash.
Two recalls address the same underlying issue with front seat-mounted side airbags: incorrect trim covers on one or both front seats can prevent the airbags from deploying properly in a crash. A related recall covers the passenger seat occupant classification sensor, which can misread whether a passenger is present and cause the front airbag to fail to deploy in a crash. These airbag concerns apply to both standard and hybrid models. On the stability side, a software fault in the electronic stability control system can cause it to deactivate unexpectedly, which only affects Highlander Hybrid models. The front lower bumper cover can come loose or fully detach during normal driving and become a hazard for other vehicles. There is also an engine control unit programming error on V6-equipped models that can cause a fuel supply interruption during the stop-start cycle, leading to a stall.
