I seen several post with this situation but no specific answers. I have LR M3 with out the slight steering wheel vibration. I just hit 2200 miles and for the last 150 miles I get a small vibration in the steering wheel at speeds above 25 MPH. The car drives straight, but it feels like a small buzzing sensation. I had the wheels rebalanced at America’s tires, they said the balance was off and rebalanced all of them, but still have the vibration. It’s not the Lane Departure Warning, I turned that off the day I received the car and it’s was smooth up until 150 miles ago.
