Defect description
Nova Bus (US) Inc. (Nova Bus) is recalling certain 1997-2002, 2005-2024 LFS, 2009-2014, and 2016 - 2024 LFS Artic transit buses. The low brake air pressure warning light may fail to illuminate when the engine is off. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 121, "Air Brake Systems."
