The recall documentation says that the TPMS fails to meet Federal Motor Vehicle Safety Standard No. 138. The problem is that the TPMS on some 2011 Toyota Tundra trucks may not have been properly calibrated, meaning light up when the temperature drops in one or more tires.
This could lead to driving on an improperly inflated tire, which could result in tire failure and an accident.
Toyota is recalibrating the tire pressure monitoring system in accordance to the safety standard free of charge. Concerned owners can contact Toyota at 1-800-301-6859, between Monday and Friday from 8:30 AM to 5:00 PM EST.
