Update: The list of car with cracked monovalves has grown to four:

Chris (Ohio)
Jane (California)
Jeremy (California)
Zulfiqar (Texas)

I am waiting to hear back from Zulfiqar; once I have the VIN of his car I can go to the dealer's service manager who will then file the report. Having this problem on multiple cars all over the country will make it harder (but not impossible!) for Mercedes to ignore.

Anyone else?

Jeremy
