What's wrong?
The grid heater electrical power cable on 2010-2015 Gillig Low Floor transit buses supplies electrical power to the engine's grid heater. That heater helps warm intake air for starting and smooth operation. Nearby, a hard injector fuel line carries fuel to the engine injectors, so the cable routing matters.
On affected buses, the grid heater power cable was zip tied to the hard injector fuel line during assembly. That tie used the fuel line as support, leaving the cable close enough to rub against it. Over time, vibration and normal bus operation can let the cable chafe on the fuel line, damaging the cable or the line. Gillig's record ties this condition to a bus fire reported in service.
The warning sign listed for this recall is a "Check Engine" light on the driver's display. If that light appears, the bus needs inspection for this cable routing issue before it stays in service.

What's the safety risk?
Contact between the electrical power cable and injector fuel line can create a short circuit or fuel leak, increasing the risk of a fire. If the "Check Engine" light appears, stop using the bus and call the dealer for inspection. Repair is free at any franchised Gillig dealer.
What should I do?
- Check your VIN to confirm your 2010-2015 Gillig Low Floor bus is included in this recall.
- Contact a franchised Gillig dealer to schedule the free inspection and rework.
- Schedule the grid heater power cable rerouting and support work that keeps the cable from rubbing the hard injector fuel line.
- Bring the recall notice if Gillig mailed one. If not, reference recall number 15V420 when you call.
- Keep the bus out of service if the dealer finds cable wear or fuel-line wear, and complete the repair before returning it to route service.
What happens at the repair
At the dealer, a Gillig technician inspects the grid heater power cable and hard injector fuel line for wear. The technician then routes and supports the grid heater power cable correctly so it stops chafing against the fuel injector hard line. The inspection and rework are free under the recall. Gillig also reimburses customers for costs tied to this inspection and rework. Keep repair paperwork and ask the service desk or Gillig customer service how to submit it.
