The defect
Shyft Group is recalling certain 2023 Spartan RV Chassis K2 vehicles. The engine control module (ECM) may experience an internal short-circuit, which can result in an unexpected engine shut down without the ability to restart the vehicle.
The risk
An unexpected engine shut down can increase the risk of a crash. Additionally, a disabled school bus may require an evacuation procedure in an uncontrolled traffic situation, increasing the risk of injury to passengers.
