The radiator fan (I assume) is super loud on my wife's 2010 GLK. Dealership said that this is normal, but I know it didn't do this for the first two years we had the car. Anyone know what the problem is? I can literally hear her a couple houses away before she gets to the driveway.

What kind of loud? Like its hot and AC is on loud, or the bearing is going out loud
