Product review (1 stars): Avoid Miele induction cooktops if you like your food actually cooked
I have a kitchen full of Miele products (induction stove, oven, steam oven and dishwasher)...all great except the induction stove (KM5773).  Since installation we have had the issue of the stove shutting off during operation.  At first it happened only occasionally (every month or so) and was of course inconvenient when cooking dinner.
However, the frequency of this issue has increased dramatically; happening every few days a few months back and now happening every day.  "Resetting the touch controls" as outlined on page 18 of the User Guide usually worked (~70%) with a trip to the basement to flip the breaker usually working the rest of the time, so this was more of a nuisance than anything.  And my general thoughts at the time were that it's embarrassing for Miele to have designed such a high end stove top that costs $3000 be prone to a ridiculous DESIGN AND ENGINEERING FLAW.
However, over the past several months we have had instances in which we could not even reset the stove...ruining meals, plans, experiences, etc. The capper was when my wife hired some chefs to come and cook for eight of us for a birthday celebration.  A night half ruined when only some of the dishes were already finished.
I'm appalled by the reliability of this unit.  From the posts online, I'm of the mind that this is NOT isolated to just me and that Miele should consider a product recall...or at least a solution.
I'm at wit's end with more ruinous experiences when I should be enjoying the not inexpensive equipment.

Note -- Miele has a website with very positive reviews of their products...all suspiciously submitted on either September 5th or 6th of 2012.  I've submitted the above review twice to no avail.

You've been warned...caveat emptor

Update 8/21/13 -- Miele wants ~$1100 for the replacement part.  Two things to note if you buy a KM5773...
First, don't assume that you'll always be able to cook your meals...you may have the power control board fail mid-meal prep.
Second, definitely get an extended warranty.
