Recall 15V262 covers 1,101 2010-2015 Gillig Low Floor buses for a crankcase vent elbow oil-leak fire risk. Free repair at any franchised Gillig dealer.
Gillig is recalling 1,101 2010-2015 Low Floor buses because excessive engine crankcase pressure can detach a 90-degree vent tube elbow from the crankcase ventilation breather. Engine oil can then reach hot surfaces and increase fire risk; Gillig dealers will complete the repair free of charge.

What's wrong?
The open crankcase ventilation breather on 2010-2015 Gillig Low Floor buses acts like an oil separator for the engine crankcase. It filters most engine oil out of pressurized combustion gases that pass from the crankcase during normal operation. A vent tube assembly then routes those gases down toward the bottom of the engine.
On affected buses, high crankcase pressure can overcome the small ridges, called barbs, that hold the 90-degree elbow of the vent tube assembly to the breather exit tube. Gillig traced the known incidents mainly to a cracked piston creating excessive crankcase pressure. When the elbow detaches, engine oil can leave the breather area and contact hot engine surfaces.
Drivers or technicians can see warning signs before this happens. The bus can lose engine power, show amber or red engine diagnostic lamps on the instrument panel, or run erratically.

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?
Engine oil on a hot surface raises the risk of fire. Watch for loss of engine power, amber or red engine diagnostic lamps, or erratic engine operation, and schedule the recall repair promptly if your VIN is included. Repair is free at any franchised Gillig dealer.
What should I do?
- Check your VIN to confirm your 2010-2015 Gillig Low Floor is included in this recall.
- Contact a franchised Gillig dealer to schedule the free repair.
- Ask the dealer to secure the 90-degree vent tube elbow and reprogram the ECM so engine output is adjusted under misfire conditions to limit crankcase pressure.
- Bring the recall notice if Gillig has mailed one. If not, reference recall number 15V262 when you call.
- Avoid operating the bus if engine oil is visible near hot engine surfaces before the repair is complete.
What happens at the repair
At the dealer, a Gillig technician secures the ends of the 90-degree elbow in the crankcase ventilation breather vent tube assembly. The technician also reprograms the electronic control module (ECM) with software that adjusts engine output during misfire conditions to limit crankcase pressure. The recall repair is available now, and the parts, software work, and labor are free under the recall.

Frequently asked questions
What is recall 15V262?
Recall 15V262 covers 1,101 2010-2015 Gillig Low Floor buses with an engine crankcase ventilation issue. Excessive crankcase pressure can detach the 90-degree elbow from the vent tube assembly, letting engine oil contact hot surfaces and increasing fire risk.
What should I do if my 2010-2015 Gillig Low Floor is on this recall?
Check your VIN to confirm your specific bus is included in recall 15V262. If it is, contact a franchised Gillig dealer or Gillig customer service at 1-800-735-1500 to schedule the free repair. Reference recall number 15V262 when you call.
Is the recall repair free?
Yes. Federal recall law requires the recall repair at no cost, and Gillig's remedy states that dealers will secure the 90-degree elbow and reprogram the ECM free of charge. Parts and labor are covered at a franchised Gillig dealer.
What is the safety risk?
The safety risk is fire. If engine oil reaches a hot surface, the bus has an increased risk of a fire. The dealer repair addresses the vent tube elbow and updates the ECM software to limit crankcase pressure under misfire conditions.
What if I bought this Gillig Low Floor used?
The free repair still applies. Recall coverage follows the vehicle, not the first owner. Check your VIN to confirm whether your specific bus is included in recall 15V262, then give that recall number to the Gillig dealer or Gillig customer service.
