Service bulletins

Toyota issued 359 service bulletins listed against this model year, most often about equipment.

A bulletin tells dealers how to fix a known condition. It is not a recall and not a defect finding. Most bulletins cover several model years at once, so one listed here may not be specific to this year. The number of bulletins tracks how long and how widely a model was sold, so it is not a measure of reliability.

How to read this page

Complaint counts are not failure rates. A model that sells more cars draws more complaints, and owners file more often after news coverage or a recall. That is why this page compares a model year only with other years of the same generation, never with other models.

Each complaint is counted once, even when it names several components; a complaint that names several systems appears under each of them. Owner reports are quoted as filed and have not been verified by NHTSA or by us.

Every model year of this Highlander, including the ones without a page of their own, is listed on the Toyota Highlander model page.
