Defect and consequence

Defect: E-One Incorporated (E-One) is recalling certain 2017-2021 Cyclone 2, Cyclone N, Quest 2, Typhoon, and Typhoon N vehicles. The sealing washer may not seat correctly in the pilot bore holes, allowing the high pressure fuel rail assembly to leak.

Why it matters: A fuel leak in the presence of an ignition source increases the risk of a fire.

Remedy

Dealers will inspect and replace the rail as necessary, free of charge. Owner notification letters were mailed out on May 28, 2021. Owners may contact E-One customer service at 1-352-237-1122.

Defect and consequence

Defect: E-One Incorporated (E-One) is recalling certain 2013-2019 Typhoon and Cyclone 2, 2013-2014 Cyclone 3, 2014-2019 Quest 2 and 2017 CHSH emergency vehicles equipped with a Cummins ISL, L9, ISX12, X12, ISX15, or X15 engine. The engines do not have a diode in the starter solenoid circuit to improve the longevity of the lock-out relay, resulting in accumulated damage over time.

Why it matters: The damaged starter lock-out relay may prevent the vehicle from starting, hindering personnel from responding to emergencies, increasing the risk of an injury.

Remedy

E-One will notify owners, and dealers will install a diode in the starter solenoid circuit and install a new starter lock-out relay, free of charge. The recall began November 15, 2019. Owners may contact E-One customer service at 1-352-861-3612. Note: Vehicles previously repaired under recall 18V-019 also need this recall remedy.

Defect and consequence

Defect: E-One Incorporated (E-One) is recalling certain 2017-2019 Cyclone II, Typhoon and Quest II emergency vehicles, equipped with Whelen accessory brake lights. Depending on the specific wiring of the vehicle, these brake lights may illuminate when the brake pedal has not been pressed. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 108, "Lamps, Reflective Devices, and Associated Equipment.".

Why it matters: If the brake lights incorrectly illuminate, it can confuse other drivers, possibly increasing the risk of a crash.

Remedy

E-One will notify owners, and dealers will replace the brake lights, free of charge. The recall began October 26, 2018. Owners may contact E-One customer service at 1-352-861-3612.
