A recall appears to be happening as we speak:

Recall Date: MAR 26, 2003
Component: STEERING:HYDRAULIC POWER ASSIST:HOSE, PIPING, AND CONNECTIONS
Potential Number Of Units Affected: 211000
ON CERTAIN PASSENGER VEHICLES, THE HOSE CLAMP USED TO SECURE THE POWER
STEERING FLUID COOLING HOSE TO THE POWER STEERING FLUID COOLER MAY NOT
PROVIDE SUFFICIENT CLAMPING FORCE FOR THIS CONNECTION.
THE LOSS OF POWER STEERING FLUID MAY RESULT IN DIMINISHED POWER STEERING
OVER TIME AND ULTIMATELY CAN DAMAGE THE POWER STEERING PUMP.
DEALERS WILL INSTALL A NEW HOSE CLAMP ON THE POWER STEERING HOSE TO THE
POWER STEERING COOLER. DURING CLAMP REPLACEMENT, THE POWER STEERING
COOLING HOSE WILL BE INSPECTED AND REPLACED AS NECESSARY. MERCEDES-BENZ

Darn! If the notice had come just 1,500 miles sooner, I'd have it taken care of as of the last FSS at about 64K. I thought about mentioning it then, based on what I'd read on the user group a long time ago, but I just tightened'm up myself at that time.
Others' experiences seemed to point to the fact that the problem for most was associated with starting the car after having sat idle in very cold weather. Probably the hose contracts somewhat in the cold and renders the clamp less effective.
#6896 of 8199 Just checked mine

I went out and tightened two clamps - one on the PS pump and the other on the radiator. There were no indications that either were about to slip off, but the clamps were not especially tight - I was easily able to turn them another turn or so. The clamps looked very cheap and cheezy for something using to clamp hydraulic fluid.
I'm perplexed why there is only a single line (that I can see) from the PS pump to the radiator. Doesn't there have to be two? Is there one underneath that can only be seen from the bottom?

Drew published Andrew Ling's update about it October 2002. Here's the link:
P.s., there is a clamp at the bottom and I think that is the one you want to check--the hose should be up against the radiator fitting.
#6898 of 8199 Power Steering Failure

One of my lines blew, or blew off, today. There's hydraulic (power steering) fluid everywhere under the hood. I understand that Mercedes will repair under terms of recall. Will they clean up the mess everywhere under the hood?

#6900 of 8199 Power Steering - No Recall
Apr 07, 2003 (11:19 am)
My service advisor told me this morning that there is no recall, only a service advisory. Thus, the hose problem is not covered if the vehicle is out of warranty. I though I had read something about a recall here a couple of days ago?
Apr 07, 2003 (12:17 pm)
I haven't received anything either, so perhaps MB is dragging their feet.
Honestly, it takes 5-minutes to tighten the clamps which probably solves the whole thing, or another five minutes and $2 worth of hose clamps if you want to to replace them. So it isn't a big deal IF you know about it. The real problem here is not with the difficulty in the repair, it is with the insidious nature of it to owners who haven't been advised about the issue.
#6902 of 8199 The Real Cost of Power Steering Problem
Apr 07, 2003 (12:35 pm)
If MB could have seen the faces of the folks on Magazine St. in New Orleans I almost hit on the sidewalk they might re-think this issue. The injuries and fatalities will be the real cost. This thing was impossible to steer. I had all my weight and muscle into the wheel and couldn't turn more than 10 degrees.

Nice article from the Washington Times by a writer (writes outdoor stories and some automotive articles) who had an accident in an ML350.
The print edition has some photos of the wreck but the on-line version doesn't.
