The power steering pump in all 2005-2010 Honda Odyssey minivans is a defective product. Some owners had it replaced more than 2 times and are still experiencing problems. Recent Honda service bulletin dictates that the old pump be replaced with a new upgraded pump (that was never used in production). If your van is still within warranty, please hurry up to get it replaced soon. If you are out of warranty, your best bet is to join the class action lawsuit, to make America Honda pay to repair the defect.
