I have had my 2.7 Auto Santa Fe for 5 months and love it! definitely the best value SUV...one problem persists however, a whining noise in the cabin (I think from the transmission) when in top gear cruising at 40mph or motorway speeds, and when decelerating. I have found examples of this happening on the net in the US but not in the UK. My dealer hasn't a clue what to do....does anyone have experience of such an issue?
