Nova Bus LFS recall: coolant sensor may shut down engine
Nova Bus recalls 928 LFS and LFS Artic buses for a coolant-sensor fault. Buses repaired under recall 24V873 still need the new repair.
Nova Bus is recalling 928 potentially affected 2022–2024 LFS and 2023–2024 LFS Artic buses because a faulty coolant sensor may trigger an engine shutdown. Campaign 26V573000 replaces recall 24V873, and buses repaired under that earlier campaign still need the new repair. NHTSA identifies the campaign as 26V573000.
What the official recall record says
Nova Bus LFS and LFS Artic: coolant-level sensor
The sensor may falsely signal that coolant is critically low, causing the engine to shut down. NHTSA identifies crash risk from an unexpected shutdown and injury risk when passengers must transfer from a disabled bus. Nova Bus will inspect the sensor and replace it as necessary at no charge. The report says the earlier remedy was inadequate and the new campaign includes the original affected population.
