Volvo is recalling certain model year 2013 S80 and XC70 vehicles. A software error within the Central Electronic Module (CEM) will result in the “TPMS Service Required” message appearing after approximately 15 minutes of accumulated driving over 25 mph. The error will prevent the Tire Pressure Monitoring System from warning the driver that a tire needs air. Thus, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard No. 138, “Tire Pressure Monitoring System.”
