Product review (2 stars): 2 stars because its pretty, but don't stare at it too hard...she'll break.
Wow.  What a piece of junk.  First off, when you pay $1800 for a range, it should work like an expensive Swiss watch.  When you put "Made in the USA" stickers on it, you're shaming our country's craftsmanship.....or maybe that was a warning.  Can you tell if it was built on a Friday?

Got the stove in September.  By October, the "safety" shutoff valve that only operates with current began to buzz.  Its an electromagnetic plunger that will stop any gas feed to the burners if not powered.  If you lose power, you cant use the gas.  There is no override.  Every time it was engaged, it would sound like a set of barber shop clippers and loud.  I called Whirlpool and played them a recording of the sound, and the actual sound and they sent a tech who confirmed what I knew.  It made me nervous to use the oven because this is a gas line component.  The tech ordered the part, and proceeded to blow me off twice over the course of 4 weeks on replacement putting the repair AFTER Thanksgiving.  I was forced to take it into my control.  It took me all of 30 minutes to replace it, but I had to confirm the work would be warrantied since I had to DIY.  I'm not sure how they expect to sell the warranties they push if they're not going to provide service at all.  Tip:  Hire people that actually care about doing a good job.

Recently, the right 16k BTU mid-range burner valve froze closed (I appreciate it didn't get stuck open).  I could tell the heat from the top oven was making something stick, but wouldnt you know that this happens a month out of the pitiful one year warranty they provide.  The valve itself is $80, which surprised me.  I guess I'll be on DIY duty for that too.  This one failed right before Xmas dinner within its first year of use.  If they start to get catchy, be ready to buy new ones.  Its a stamped/cast part that cant be cleaned.  Yay obsolescence and the throw away society!

It doesnt get heavy use.  Its me and the wife and we probably cook on it 3 times a week.

The final nail in its coffin was when I washed the stainless knobs (which are too heavy for the valve spring actuation to work properly).  Something in the back of the knob connection is water soluble because now none of the 5 knobs fit on the valve stems at all.  I'm looking to source for lighter knobs so that the spring has a fighting chance.

Cliffnotes:  Avoid KitchenAid (or Whirlpool for that matter).  They're made cheaply, they break easily and their service is awful.  What kicks me in the gut is that I bought it through the "VIP" program.  The one year warranty is a joke.  They will constantly call, write, and email you about their warranty program, which costs about $100 a year (go figure).  You'll need it if you buy one.  3 failures in the first year of use is unacceptable.
They kept asking me if I had used the self-clean feature and wouldn't say why they were asking.  I'm seriously afraid to that feature now.

Stainless?  More like Gillette thin razorblade construction with an appetite for fingerprints.  The thing is very hard to keep clean, and it can cut you good if you're not aware of the edges.

Also, if you don't have a in-wall 4 prong plug set exactly at the back indentation where the book shows, forget it.  There is no bottom cabinet room for any kind of mistake and will never sit flush agaist the wall.  That cost me another $120 in copper wire, an outlet, box, and an entire evening.  This aint like the ones that sit over top of the floor mount box you find in a lot of homes.

What happened to the days with something like an oven could last 20 years without incident?  This stove is dangerous IMHO.  I would send it right back to them for a refund if they stood behind their products.
