Looking for a bit of advice. Over past 2/3 days we have heard a strange droning/humming noise coming from the vehicle. It appears to be coming from the front end and is extremely loud when doing approx 40 to 50 MPH and gets worse when speeding up and slowing down (sounds just like a faulty wheel bearing) Has anyone els had this problem. I did think it could have been the tyres but the vehicle is only 4 months old and covered 3500 miles from new. It is going into dealer later this week so hopefully will get to the bottomof the problem.
