Recall 10V127 affects 191 2006-2010 Champion buses with Trans/Air relay boards that can overheat and create a fire hazard. Repair is free.

Champion is recalling 191 2006-2010 buses, including Ic Low Floor and Ez-Trans models, because Trans/Air air-conditioning electrical kits can overheat when the relay board and EC PC board are installed incorrectly. An electrical failure in the relay board poses a serious fire hazard, and the Champion dealer repair will be free once available.

What's wrong?

The air conditioner on these 2006-2010 Champion buses uses a Trans/Air system, not just vents and fans. Its electrical kit includes a relay board and an EC PC board, which route power and control signals so the air conditioning can switch on, cycle, and run without overloading the wiring.

The defect is in how that electrical kit was installed on certain buses with Trans/Air systems installed from May 2006 through June 2009. If the relay board or EC PC board is installed improperly, electrical current and heat concentrate where the system was not designed to handle it. That can make the board overheat instead of carrying the load cleanly.

There is no warning sign before failure. An owner or operator should not count on a dashboard light, noise, smell, or change in cooling performance to appear before the electrical kit overheats.

What's the safety risk?

An electrical failure in the relay board can overheat and create a serious fire hazard. NHTSA campaign 10V127 does not list a warning sign before failure. Schedule service promptly, and keep the bus out of service if you notice overheating or electrical trouble. Repair will be free at any franchised Champion dealer once available.

  1. Check your VIN to confirm your 2006-2010 Champion Ic American Coach, Challenger, Hc 270NF, Ic Low Floor, Ic High Floor, American Coach, Ez-Trans, or Defender bus is included in this recall.
  2. Contact a franchised Champion service location to ask about current repair instructions for the Trans/Air air-conditioning electrical-kit recall.
  3. Ask about the free relay-board and EC PC-board repair that addresses overheating in the air-conditioning electrical kit.
  4. Bring the recall notice if Champion or Trans/Air mailed one. If not, reference recall number 10V127 when you call.
  5. Park the bus away from buildings and avoid using the air-conditioning system until the electrical-kit repair is complete.
