Bilstein Shock Reservoir Fell Off

Well...this is a new one by me. I went out to the garage the other morning and noticed a pool of oil under my passenger rear tire. I jokingly thought to myself "Well....I better pick up some tire fluid while I'm out today.". But my joking attitude was quickly squelched when I discovered that it was coming from my shock. And the entire external reservoir was completely missing. I say this with the utmost embarrassment....but I have not had this thing off road at all yet. I live in boring, flat Indiana. The most off roading I've done was on maintained dirt roads when we visited Sleeping Bear Dunes in Michigan last summer. I wholeheartedly plan on putting this thing through its off road paces...I just haven't gotten anywhere to do it yet. I drove to work. No leak. I drove home from work, not hitting so much as a pothole, and then woke up the next morning to it leaking. While having this thing just fall apart on me is not that surprising from a Ford quality perspective, it IS somewhat a surprise from a Bilstein perspective. I think of them as THE name in shock absorbers. To have one fall apart at 24000 miles seems nothing short of ridiculous. I have an appointment to get it looked at next week. I have found a few other examples of people running into this issue, and getting it replaced under warranty seems to be a crap shoot. Anybody else experienced this?
