If the owner does not have any brake service or maintenance performed over a period of months or years, the system can continue to accumulate enough air to affect braking performance, increasing the risk of a crash.
Honda has notified NHTSA of a defect in certain model year 2007 and 2008 Odyssey and Element passenger vehicles manufactured between July 28, 2006 and August 21, 2008. Air can enter the vsa modular pump during an initial self-check process that occurs shortly after each time the engine is started. It is possible for enough air to enter the system to result in a brake pedal that feels soft or lower to the floor.
Honda will notify owner and Honda dealers will repair the vsa modulator by removing any existing air in the brake system then apply sealant and caps to prevent air from entering the brake system free of charge. The safety recall began on May 3, 2010. Owners may contact Honda at 1-800-999-1009.
