Nova Bus LFS Recall 18V117: Hot coolant may leak into bus passenger area

NHTSA campaign 18V117, reported February 17, 2018, 24 vehicles potentially affected.

What this recall means for you

Certain 2013 Nova Bus LFS transit buses have transmission oil coolers that can fail. If that happens, transmission fluid can mix with the coolant that circulates through the passenger heating system, and the fluid can degrade the plastic PEX connectors in that system. Hot coolant may then leak into the passenger area.

Leaking hot coolant could come into contact with passengers and increase their risk of injury. Owners will be notified by Nova Bus, and the remedy is free: authorized dealers will replace the PEX fittings with brass fittings at no charge. The recall began March 6, 2018.

If you operate or own one of these buses, contact Nova Bus customer service at 1-800-350-6682 and check your vehicle identification number (VIN) for open recalls.
