The defect
Prevost Cars, Inc. (Prevost) is recalling certain 2017-2020 X3-45 Coach, Commuter, VIP, and VIP Entertainer buses, and H3-45 Coach and VIP buses. Under certain conditions, such as high altitude and heavy climbing, the engine may overheat and shutdown.
The risk
If the engine unexpectedly shuts down, passengers may have to be transferred to another vehicle on the side of the road, increasing the risk of an injury. If the engine unexpectedly shuts down while the vehicle is in motion, there is an increased risk of crash.
