Toyota Highlander TSBs
The Highlander has been assigned 817 technical service bulletins (TSB). The 2014 model year has been involved in the most bulletins.
TSBs contain recommended steps and procedures for diagnosing or repairing a known problem. They are issued directly by Toyota to service technicians. You'll often see TSBs used as evidence in lawsuits when owners feel the automaker should help with repairs.
