DEALER SEEMS UNABLE TO FIX THE PROBLEM AFTER 4 TRIES. ANY HISTORY OF THIS PROBLEM?
2011 MERCEDES C 300 4MATIC DRIFTING TO THE LEFT, HAVE TO CONSTANTLY CORRECT on 2011 Mercedes-Benz C300 4MATIC
No history I'm aware of. Have the tires Road force balanced AND "Straighttrac" procedure performed- If your dealer doesn't use this, look for one who does. If they have recommended tires, you might have to bite the bullet.
