What is wrong
Nova Bus (US) Inc. (Nova Bus) is recalling certain 2023-2024 LFS Artic and 2022-2024 LFS buses. The coolant sensor could send a false signal, causing the engine to shut down.
The risk
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.
Why engine defects matter: Losing engine power at speed increases the risk of a crash, and fluid leaks near the exhaust are a fire risk.
The remedy
Nova Bus will inspect and replace the coolant sensor as necessary, free of charge. Owner notification letters are expected to be mailed November 2, 2026. Owners may contact Nova Bus customer service at 1-800-350-6682. Nova Bus's number for this recall is CR5936. This recall supersedes Recall 24V873. Vehicles repaired under the previous recall will need the new repair completed.

Check by VIN
A campaign rarely covers every vehicle of a model year. Enter your 17-character VIN to find the recall campaigns filed for your make, model and model year. The VIN is on the driver’s side of the dashboard (visible through the windshield), on the door-jamb label, and on your registration and insurance documents.
Is a recall still open on your vehicle? Only NHTSA’s official VIN check can say whether a campaign applies to your exact vehicle and whether the repair has already been done.
Your VIN is decoded with NHTSA’s public vPIC service to identify the make, model and year. It is not stored and is not added to any page address.
