Honda recalls 870,000 vehicles .
THE VEHICLES: Honda is recalling more than 870,000 minivans and SUVs worldwide, including 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 period.
THE PROBLEM: 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. Some have left the vehicles, which have rolled off unexpectedly while in gear.
THE FIX: Dealers will repair the ignition interlock system free of charge. Owners will get notices starting in February.
