What's wrong?
The X15 engine crossmember on 2022-2024 E-One Cyclone Ii, Cyclone N, and Typhoon N vehicles is a frame member that supports the engine mounting area. It helps hold the engine in position so nearby cooling parts, including the engine fan and fan shroud, stay properly spaced while the vehicle is running.
On affected vehicles, an engineering error in the crossmember design leaves that support vulnerable to cracking or breaking. If the crossmember breaks, the engine fan can move into the fan shroud. Contact with the shroud can damage the fan and the cooling system parts around it.
There is no warning sign before failure. The filing does not identify a noise, vibration, or other symptom owners can rely on before the crossmember fails.
