The National Highway Traffic and Safety Administration has announced that Pierce is recalling certain model year 2010-2012 ARROW XT, DASH CF, QUANTUM and VELOCITY emergency vehicles manufactured from October 13, 2010 through February 8, 2012, and equipped with Detroit Diesel DD13 EPA 2010 engines. The engine shutdown software normally provided to protect the engine and vehicle may not have been disabled on engines intended for emergency vehicle applications. If the vehicle operator receives and ignores multiple warnings indicating the need for operator intervention, the engine may shut down unexpectedly and could hamper rescue operations and place the public at risk.
