My BMW is under 6 months old with less than 4000 miles and has been back to the dealer for the same problem. It has an annoying vibrating sound from the engine. The dealer changed the power steering pump and problem still exists; now I am told it might be an engine mount. I would like to return this truck because I am fed up of the inconsistency of what a new car should have. I should have kept my infinti qx4.
