I'm positive that MBUSA has paid for rust repair on W210 still under warranty at the time. That consititutes "acknowledgement."
When past the warranty period, there's not much recourse unless perhaps if you are the original owner of the car and have had it religiously serviced at the original selling dealer.
The description in the previous paragraph describes how any manufacturer would treat this, not just Mercedes. The only "free" fixes you can expect from any manufacturer save this, are safety recall issues.
