Vehicle recall 19V730000 · October 14, 2019

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.

Summary
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.
Consequence
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.
Notes
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 www.safercar.gov.

Vehicles covered

As listed by NHTSA. A recall usually covers only some vehicles of each model and year, often a production date range.

Has your E-One been repaired?

Recalls here come from NHTSA’s records for the model and year. Not every vehicle of a model is included in every recall, and this site can’t see whether a repair has been done. Only a VIN lookup can tell you that.

NHTSA’s VIN search doesn’t show recalls that were already repaired, recalls more than 15 years old, or some small manufacturers’ recalls. A E-One dealer can also check your VIN. Recall repairs are free.
