...anyone else experienced this? After driving my HO 2007 on the freeway I notice a constant hum/whine/vibration-like noise coming from the front-end. My husband (a mech engineer in the automotive industry) says it is the power steering pump. To date we are unable to duplicate this for the dealer, but will try again. Have any other Honda Odyssey 2007 owners experienced this problem? There was a TSB for the 2006 HO power steering pump, but not one for the 2007.
