    Tires:pressure monitoring and regulating systems

    Southeast Toyota Distributors, LLC (SET) is recalling certain model year 2015 Toyota Prius C vehicles manufactured April 20, 2015, to June 30, 2015. In the affected vehicles, the Tire Pressure Monitoring System (TPMS) may be improperly calibrated and, as a result, the TPMS may fail to warn the driver that the tire pressure is low. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) No. 138, "Tire Pressure Monitoring Systems."

    Risk: If the vehicle is driven on underinflated tires, the tires may fail. Sudden tire failure increases the risk of a crash.

    Remedy: SET will notify owners, and dealers will re-calibrate the TPMS, free of charge. The recall began on September 15, 2015. Owners may contact SET customer service at 1-866-405-4226. SET's number for this recall is SET15E.
