Temsa Global is recalling certain model year 2011-2013 TS35C and 2012-2013 TS30 motor coach buses. First, the two service air brake pressure gauges are both reading the pressure of the same air tank. Second, the ABS system malfunction indicator light does not illuminate momentarily when the key is turned to the 'ON' or 'RUN' position. Thus, these vehicles fail to comply with Federal Motor Vehicle Safety Standard No. 121, "Air Brake Systems."
Without accurate gauges, the driver may not notice the pressure change in the secondary brake system. The driver may also not be aware of an ABS issue without the bulb illuminating each time the key is turned on. Either issue increases the risk of a crash.
Temsa will notify owners and they will update the software, free of charge. The recall began on June 3, 2013. Owners may contact Temsa Global at 1-404-602-0151.
Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov.
