Stallion 900 Motorcoaches Subject of Another NHTSA Defect Investigation

March 3, 2015

The National Highway Traffic Safety Administration (NHTSA) has launched a new defect investigation into model year 2014 Stallion 900 series motorcoaches.

NHTSA's Office of Defects Investigation (ODI) says that it was made aware of a fleet of the Stallion 900 buses that has experienced multiple incidents of wiper electrical system failures.

According to the fleet operator, the wiper circuit overheats and disables the motor. The fleet further alleges that attempts have been made by both it and the manufacturer to address the concern, including replacing the original 20 amp fuses with 30, and then 40 amp fuses; and that the 40 amp fuses may result in burned inverters.

Several failures have allegedly occurred, and continue to occur, resulting in the buses being stranded on road shoulders waiting for weather to improve or relays to cool down. ODI says that it is not aware of any injuries associated with this issue.

ODI is opening this investigation to gather additional information and assess the scope, frequency, and consequences of the alleged defect.

The ODI reports cited above can be reviewed at under the identification (ODI) number 10630768.

This is one of two active NHTSA investigations involving Stallion 900 motorcoaches. Just last month an investigation was launched into model year 2014 Stallion 900 motorcoaches after reports of seatbelt buckle assemblies failing to unlatch.
