Prevost Cars (Prevost) is recalling certain model year 2014 H3-45 coaches manufactured August 29, 2013, through November 19, 2013 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.”
