Affected trucks are from the 2018-21 model years and were produced between June 2017 and March. The headlights allow the circuits for both the high- and low-beam bulb filaments to be energized at the same time when the high beams are switched on. Under some conditions, Toyota said in a statement that if the high beams are repeatedly left on for an extended period while the truck is idling or driving at low speed, there’s a possibility that the bulb connector could overheat and can result in an increased risk of a fire that can spread to other parts of the vehicle.
To fix the issue, dealers will modify the engine wire harness assembly and inspect the headlight bulb connector, bulb and headlight assembly. If a component is found to be damaged due to overheating, they’ll be replaced with new ones. Toyota will notify owners by Nov. 1, but if you have further questions in the meantime, you can call the automaker at 800-331-4331, the National Highway Traffic Safety Administration’s vehicle-safety hotline at 888-327-4236 or visit its website to check their vehicle identification number and learn more.
