Honda is recalling more than 870,000 minivans and SUVs worldwide -- 807,000 in the U.S. -- because they can roll away even though drivers have removed the keys from the ignition. The recall covers 347,000 Honda Odyssey minivans and 277,000 Pilot SUVs from the 2003 and 2004 model years, as well as 247,000 Acura MDX SUVs from the 2003 through 2006. All have automatic transmissions. More than 807,000 were sold in the U.S. The problem is that the mechanism that locks the key in the ignition while the vehicles are in gear can wear out. When that happens, drivers of the vans and SUVs are able to remove keys without shifting into park.
