Nova Bus LFS buses recalled for defective coolant sensor causing engine shutdown
What this means
A coolant sensor in certain 2023–2024 Nova Bus LFS Artic and 2022–2024 LFS buses can send a false signal, causing the engine to shut down without warning. An unexpected shutdown increases crash risk and can create unsafe conditions when passengers need to be transferred from a disabled bus.
- If you own or operate one of these buses, contact Nova Bus customer service at 1-800-350-6682 or reference recall number CR5936.
- Owner notification letters will be mailed November 2, 2026.
- Nova Bus will inspect and replace the coolant sensor at no cost.
- If your bus was repaired under the previous recall (24V873), the new repair will still be needed.
The agency's original wording
An unexpected engine shut down can increase the risk of a crash. Additionally, transferring passengers from the disabled bus can increase the risk of injury.
