Kovatch Mobile Equipment Corp. (Kovatch) is recalling certain model year 2013-2014 Predator and 2014 Panther fire fighting vehicles manufactured October 2013 to March 2014, and equipped with IMMI-brand L9 seat belt buckles. When the button is pressed to release the seat belt, the latch plate can become partially engaged with the buckle, making the seat belt difficult to unlatch. Thus, these vehicles fail to conform to the requirements of Federal Motor Vehicle Safety Standard (FMVSS) No. 209, “Seat Belt Assemblies.”
