What's wrong?
On 2012-2014 Gillig Low Floor buses, the affected parts are electrical harnesses with overmolded J1939 connectors. A harness is a bundled set of wires that carries power and signals between vehicle systems, and a J1939 connector is a communication plug used by heavy-duty vehicle electronics. The overmold is the molded covering around the connector that helps seal and protect the wiring.
The problem is at the connector and drain wire. These harnesses do not have heat shrink tubing on the drain wire, and the overmold does not have enough resistance to water or corrosive chemicals entering the connector. Once moisture or corrosion reaches the terminals, the electrical connection can degrade instead of carrying a clean signal.
The filing does not identify a warning sign an owner or operator would notice first. There is no warning sign before failure.
Who's affected?
The listed vehicles are all Low Floor buses across the 2012, 2013, and 2014 model years, with the same wiring component.

A matching year and model does not guarantee inclusion. Check your VIN to confirm whether your specific bus is included.
What's the safety risk?
Corroded terminals can interrupt the J1939 communication network. That loss can disrupt the engine, transmission, ABS, and body controllers, which increases the risk of a crash. Schedule service soon and tell the dealer about any electrical interruptions. Repair will be free at any franchised Gillig dealer once available.
What should I do?
- Check your VIN to confirm your 2012-2014 Gillig Low Floor bus is included in this recall.
- Contact a franchised Gillig dealer to ask about the free overmold-connector repair, which helps protect J1939 communication from water and corrosion damage.
- Bring the recall notice if Gillig mailed one. If not, reference recall number 14V222 when you call.
- Call Gillig customer service at 1-800-735-1500 with questions about scheduling or fleet service records.
- Keep operators alert for engine, transmission, ABS, or body-controller interruptions until the repair is complete.
What happens at the repair
At the dealer, a Gillig technician will replace the overmold connector and add heat shrink tubing at the connector and cable junction. That work addresses water and corrosive chemical entry at the harness connection. The dealer repair will be free once available, with parts and labor covered by the recall. Before arranging service, ask the Gillig service desk to confirm that recall 14V222 is open for your bus.
