Recall 18V019 affects 1,147 2013-2017 E-One Quest Ii, Cyclone Ii, and Typhoon emergency vehicles for starter-relay damage. Repair is free at any franchised E-One dealer.
E-One is recalling 1,147 2013-2017 Cyclone Ii, Typhoon, and Quest Ii emergency vehicles because missing diode protection in the starter solenoid circuit can damage the starter lock-out relay over time. A damaged relay can keep the vehicle from starting and delay emergency response, and E-One dealers will complete the repair free of charge.

What's wrong?
The starter system on 2013-2017 E-One Quest Ii, Cyclone Ii, and Typhoon emergency vehicles uses a starter solenoid to send power to the starter motor when the engine is started. These vehicles also use a starter lock-out relay, an electrical switch that helps control the start circuit so the starter engages only when it should. The affected Cummins ISL, L9, ISX15, and X15 engine setups are missing a diode in that circuit. A diode acts like a one-way electrical check valve and protects the relay from voltage spikes.
During startup, the starter solenoid sends high transient voltage back through the circuit. Without the diode, those voltage spikes damage the starter lock-out relay over time. Vehicles with frequent start and stop use place more stress on that relay, and a damaged relay can lead to an intermittent no-start condition.
The warning sign is hard starting, or a vehicle that requires multiple attempts before it starts. That starting trouble is the issue to describe when discussing the recall repair.

The year and model narrow the scope, but the VIN decides. Check your VIN to confirm whether your specific vehicle is included.
What's the safety risk?
A damaged starter lockout relay can stop the vehicle from starting, delaying emergency response. Hard starting or repeated start attempts are warning signs to treat seriously before the vehicle is needed for a call. Repair is free at any franchised E-One dealer.
What should I do?
- Check your VIN to confirm your 2013-2017 E-One Quest Ii, Cyclone Ii, or Typhoon is included in this recall.
- Contact a franchised E-One dealer to schedule the free starter-solenoid diode and starter lock-out relay repair that helps prevent a no-start condition during emergency response.
- Bring the recall notice E-One mailed, and reference recall number 18V019 when you call.
- Keep backup response plans in place until the repair is complete because a damaged starter lock-out relay can prevent the vehicle from starting.
- Call E-One customer service at 1-352-861-3612 with questions about service timing.
What happens at the repair
At the dealer, an E-One technician installs a diode in the starter solenoid circuit and adds a new starter lock-out relay. The diode protects the relay from accumulated electrical damage that can build up over time in the starting system. Parts and labor are free under the recall, and the remedy is available now. When scheduling service, tell the dealer this is recall 18V019 so the correct starter circuit repair is prepared.

Frequently asked questions
What is recall 18V019?
Recall 18V019 covers 1,147 2013-2017 E-One Quest Ii, Cyclone Ii, and Typhoon emergency vehicles with certain Cummins engines. The starter solenoid circuit lacks a diode, which can damage the starter lock-out relay over time and prevent the vehicle from starting during an emergency response.
What should I do if my 2013-2017 E-One Quest Ii, Cyclone Ii, or Typhoon is on this recall?
Check your VIN to confirm your specific emergency vehicle is included in recall 18V019. If it is, contact a franchised E-One dealer to schedule the starter circuit diode installation and starter lock-out relay replacement. Reference recall number 18V019 when you call.
Is the recall repair free?
Yes. Federal recall law requires manufacturers to repair safety defects at no cost, and E-One dealers will install the diode and replace the starter lock-out relay free of charge. Parts and labor are covered for vehicles included in recall 18V019.
What is the safety risk?
The safety risk is a no-start condition during emergency response. If the starter lock-out relay is damaged, the vehicle can fail to start when personnel need it for an emergency call. The dealer repair adds the diode and replaces the relay to correct the defect.
When did the recall repair become available?
The recall repair began on February 19, 2018. E-One told owners to contact customer service at 1-352-861-3612, and dealers were instructed to install the diode in the starter solenoid circuit and replace the starter lock-out relay at no charge.
