Toyota will be contacting the owners of certain 2020 Highlander vehicles equipped with 3.5 L, V6 (2GR-FKS) gasoline engines that contain the Stop & Start Engine System that monitors your brake pedal operation to stop your engine when the vehicle is stopped.
The vehicles involved contain an engine control unit (ECU) programming error that may not correctly supply fuel to the engine when this feature is activated. The problem could result in an unexpected stall followed by an audible chime and multiple warnings indicating the engine has stalled.
Dealers will correct the problem by reprogramming the ECU. Toyota’s number for this recall is 20TA06 and the NHTSA campaign number is 20V162.
