E-One is recalling emergency vehicles equipped with a Cummins ISL L9, ISX12, X12, or X15 engine. The engines do not have a diode in the starter solenoid circuit to improve the longevity of the lock-out relay. High stop/start duty cycles could cause failure of the relay over time.
A potential 1,603 units are affected, including certain 2013-2019 Typhoon and Cyclone 2, 2013-2014 Cycle 3, 2014-2019 Quest 2, and 2017 CHSH emergency vehicles.
