Known issues on the 2020 Highlander. Three recalls are on federal record for this model year. One covers the occupant classification sensor for the air bags, where an air bag that does not deploy during a crash increases the risk of injury. A second covers gasoline fuel delivery on 2020 Highlanders equipped with a 3.5 L, V6 gasoline engine, where improper fuel supply programming can result in a vehicle stall, increasing the risk of a crash. The third covers the air bags on 2020 Highlander and Highlander hybrid vehicles: incorrect seat trim covers on one or both of the front seats, and improper deployment of the seat-mounted side air bag increases the risk of injury. Owners have filed 336 complaints for the year and Toyota has issued 169 technical service bulletins.
Whether you are chasing a stall on the V6, tracing an occupant classification fault, or working through a hybrid service interval, it keeps you on Toyota's own procedure and the correct 2020 Highlander figure.
