WDD series steering lock

Mercedes Benz is ripping us off. Their WDD series steering lock is designed to go off soon after the warranty expires. This is apparently a general problem with their cars. I now have to pay over R10 000.00 for their poor quality parts. I don't understand why can't they recall all these cars and fix the problem. I've had many of their customers complaining about the same issue. This sucks indeed. Fix your problem Mercedes<br>
