Starter Lock-Out Relay Failure Causing No-Start - 2013-2019 E-One Typhoon & Cyclone 2, 2013-2014 Cyclone 3, 2014-2019 Quest 2 & 2017 CHSH Emergency Vehicles

October 14, 2019 NHTSA CAMPAIGN NUMBER: 19V730000

Starter Lock-Out Relay Failure Causing No-Start

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


NHTSA Campaign Number: 19V730

Manufacturer E-One Incorporated


Potential Number of Units Affected 1,603



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.



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 is expected to begin December 2, 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.



Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to
