E-ONE CYCLONE II

ENGINE AND ENGINE COOLING:ENGINE:DIESEL

E-One Incorporated (E-One) is recalling certain 2020-2024 Cyclone 2, Typhoon N, 2021- 2024 Cyclone N, and 2021 Quest 2 vehicles. The engine crossmember may break, allowing the cooling fan to contact the fan shroud and become damaged.

Risk: A damaged cooling fan can result in an engine stall while driving and increase the risk of a crash.

ENGINE AND ENGINE COOLING:COOLING SYSTEM:FAN

E-One Incorporated (E-One) is recalling certain 2022-2023 Cyclone 2, 2022-2024 Cyclone N, and Typhoon N vehicles. The engine crossmember may break, allowing the cooling fan to contact the fan shroud and become damaged.

Risk: A damaged cooling fan can result in an engine stall while driving and increase the risk of a crash.

ELECTRICAL SYSTEM:WIRING

E-One Incorporated (E-One) is recalling certain 2021-2023 ARFF, Cyclone N, 2020-2024 Commercial, 2020, 2022-2023 Cyclone 2, 2023 Cyclone E, 2022 Typhoon, and 2020-2023 Typhoon N vehicles. In the event of a short circuit or wiring failure, the firmware in the vehicle multiplex system may fail to shut off the output pin, resulting in overloaded electrical circuits.

Risk: Overloaded electrical circuits can overheat, increasing the risk of fire.

STEERING

E-One Incorporated (E-One) is recalling certain 2022-2023 Cyclone 2, Cyclone N, Typhoon N, and 2023 Cyclone E vehicles. The steering assist bracket may have been machined incorrectly.

Risk: The incorrectly machined bracket may cause a reduction in hydraulic force, requiring greater steering effort and increasing the risk of a crash.

POWER TRAIN:AUTOMATIC TRANSMISSION:COOLING UNIT AND LINES

E-One Incorporated (E-One) is recalling certain 2022-2023 Cyclone 2, Cyclone N, and Typhoon N vehicles. The transmission cooler may be insufficiently welded, which can result in engine coolant contaminating the transmission fluid.

Risk: Contaminated transmission fluid may cause transmission failure and a loss of drive power, increasing the risk of a crash.

ENGINE AND ENGINE COOLING:EXHAUST SYSTEM

E-One Incorporated (E-One) is recalling certain 2019-2021 Cyclone 2 and 2020-2021 Typhoon N emergency vehicles. Exhaust heat may build up inside the vehicle body in certain situations such as heavy engine use, possibly causing nearby components to overheat.

Risk: Overheated components can increase the risk of a fire.

EQUIPMENT:EMERGENCY:SIREN/LIGHTING/STROBES:WIRING

E-One Incorporated is recalling certain 2022 Commercial, Cyclone 2, Cyclone N, and Typhoon N fire trucks. An additional resistor was incorrectly installed on the printed circuit board, which can disrupt CAN network communication and cause vehicle lighting to fail.

Risk: Inoperable vehicle lighting can reduce visibility and increase the risk of a crash.

STEERING:LINKAGES:TIE ROD ASSEMBLY

E-One Incorporated (E-One) is recalling certain 2022 Cyclone 2, Cyclone N, and Typhoon N vehicles. The tie rod clamps may have been improperly heat-treated, causing them to crack and allowing the tie rods to separate.

Risk: Tie rod separation can result in a sudden loss of steering, increasing the risk of a crash.

FUEL SYSTEM, DIESEL:FUEL INJECTION SYSTEM:FUEL RAIL

E-One Incorporated (E-One) is recalling certain 2019-2021 Cyclone 2, Quest 2, 2020-2021 Typhoon N, 2020 Typhoon, and 2021 Cyclone N vehicles. The fuel tubes between the fuel rail and the injectors for cylinders four, five, and six may fatigue and crack, which can result in a high pressure fuel leak.

Risk: A high pressure fuel leak in the presence of an ignition source can increase the risk of a fire.
