I've said it before, but if an owner isn't happy with the status quo and the offer from MMC, their option is to go to court, though I suspect one or two disgruntled owners may have done this, and rather than let this happen, MMC may have caved in but insisted on a clause prohibiting people saying what has happened. I would in their position.
In a way, I have mixed feelings. On the one hand, as a consumer I want justice, and on the other I want MMC to survive to fight another day, which they may very well not if they are inundated with warranty claims, whether their own fault or not.
