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."
Safety risk
A low brake air pressure warning light that fails to illuminate when the engine is off will not alert the driver to a low brake pressure condition, increasing the risk of a crash if the parking brake is disengaged before starting the engine.
Manufacturer remedy
Nova Bus will update the firmware, free of charge. Interim owner notification letters explaining the safety risk were mailed by July 17, 2026. Owners will receive another notice once remedy becomes available. Owners may contact Nova Bus customer service at 1-450-472-6410. Nova Bus' number for this recall is CR5918. Vehicle Identification Numbers (VINs) involved in this recall will be searchable on NHTSA.gov beginning October 2, 2026.
