Nova Bus LFS: Fuel System
Affects Nova Bus LFS · 2022–2025 — about 395 vehicles.
The hazard
Issue: On certain transit buses, the O-ring for the fuel management module could fail and cause a compressed natural gas (CNG) leak. If this happens, the gas detection alarm could cause the engine to shut down. Note: This recall only affects buses equipped with a CNG engine. Safety Risk: A sudden loss of power to the wheels could increase the risk of a crash. A bus that is disabled could result in a transfer of passengers in an uncontrolled environment, which may create a risk of injury. Corrective Actions: Nova Bus will notify owners by mail and provide you with instructions for how to replace the O-ring in the fuel management module.
