Champion Bus Defender
The defect
Champion Bus, Inc. (Champion) is recalling certain model year 2014 Defender shuttle buses built on Freightliner M2 chassis, equipped with Eaton-brand hybrid automated transmissions. The software controlling the affected transmissions may improperly raise the vehicle's engine speed during downshifts without the driver's input.
The risk
The increase in engine speed may result in unintended acceleration, increasing the risk of a crash.
The remedy
Daimler Trucks North America (DTNA), manufacturer of the Freightliner chassis, has notified owners, and Eaton authorized service facilities has updated the Hybrid Control Module Software version, free of charge. The recall began in May 2014. Owners may contact Champion Bus at 1-810-724-6474. Customers may also contact Eaton at 1-800-386-1911.
