This issue is already a well-discussed topic on both Tech Help and ML forum (see "Sticky" at the top of this thread list)...
...and I got mine replaced a year ago after the first reports...
...and the loss of power steering isn't the biggest issue...it's the fact that when it does disentigrate, it gouges the protruding oil pan casting, leaving the stranded motorist with an $1100 repair bill (at the very least)!
