I purchased a new 2013 Pilot on 11/26/13 which made my second new Pilot in about six years. Unlike my previous 2008 Pilot I noticed a distinct vibration while in the ECO Mode when applying light pressure to the fuel pedal. The vibration could be felt in the stirring wheel, console and floor of the vehicle. When I returned it to the dealership I was told this vibration was a typical characteristic when entering and exiting the ECO Mode. As I told the Service Manager the only problem with that explanation is that it's constant and NOT periodic. I took a trip of 500 miles shortly after the purchase and there was so much vibration while in Cruise I almost went "nuts." Needless to say I didn't get any satisfaction with the dealership and decided to take it to the next level. After sending a letter to Honda Customer Care I received a call back and was told I would be contacted and apprised of my options. This call was on 2/11/13 and as of 3/6/13 I have heard nothing from Honda Customer Care, I guess that means I have ZERO! options.....D.F.
