Failure of a new one would not do the Mercedes brand reputation much good. They should have learnt by now what the solution was, I have not had a failure on my RCMs and I have had a Crossfire for close to twelve years now, not many miles though.
I would not hesitate to use a brand new one. The only thing that would deter me is the price, the cheapest are about $130 each as I recall. I carry a spare, in fact what was my spare is now in the car as I decided to see if it worked OK.
