wobbling pulley on > 2000 SL?

I read an evaluation of a 2001 SL500 on and was surprised to find the following:

“... we’re aware of failing crankshaft pulleys on many of the 2000 and later V-6 and V-8 cars. If left unchecked the wobbling pulley will slowly machine a nice groove in the front engine cover eventually requiring its replacement, a very expensive repair... “

I had never heard about this before. Is this a common problem on our cars?

The specific part you're referring to is the harmonic balancer. On some model years involving the 113 engine, the balancer was found to defective and part of a recall by MB. An advance search on 'harmonic balancer' should bring up the previous discussions of this recall.
This link will take you to a schematic that shows the harmonic balancer (with the pulley on the end of it) also refered to as a 'vibration absorber'.
