- Published by: Transport Canada \(Canada\)
- Campaign number: 2025540
- Manufacturer's number: CR5804
- Reported: 2025\-10\-09
- Component: Fuel System
- Notification type: Safety Mfr
- Units potentially affected: 395

## What is wrong

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.
