i only have 2000 on my outlook. in the past miles driven i usualy had the air on. the other night it was cold but i wanted fresh air. so i rolled down the rear windows and left the fronts closed. a horrible ear hurting seat shacking acurance happened and i thought that i had a wheel bearing problem. i took the car back to the dealer and they had a mechanic drive with me. the acurance happened when you reach about 28 miles an hour. got back to the dealer and he gave me a letter document #1962475, pit4355-{04-18-2007]. it states that the helicopter noise is known as buffeting. no gm fix but to buy dealer acceserry window deflectors. but you still have to roll down the front window to release cabin pressure. you can release cabin pressue without the 80.00 plus install items. this does not fix the design problem. i grew up with station wagons, chevy suburbans and never had this kind of problem. a friend of mine has a ford explorer and this doesn't happen. i think i will test drive other suv type vehicles [as the document says] to see if they have the same accurance. my neighbor has a chevy trail blazer and i asked him to try this with his car. i think this doc that gm has put out for all 3 lambda platform crossovers is a cover up for some design probems.what ever happened to flow through ventilation witch would cancell cabin pressure? what about vents in the rear pillers, or liftgate vents to releave pressure in the cabin.
i was happy with the car untill this happened. i hope that pete nico or somebody else up there in this organization can make me satisfied with the purchase of this [ junk design] and give me a better explenation than this cover all document 1962475.
