I bought Kitchenaide Oven/Micro unit Model number KEMS308SSS05; SN#D20538867.  It was 4 times been repaired in the 2 years 4 months since I purchased.  Up until now its been under warranty, although I also purchased the extended warranty.  3 weeks ago the unit once again failed, the parts have been unavailable.  I was told this week that maybe the end of December the parts could be available or they will "one time" replace the unit at a prorated amount of $1,100.00.  I thought KitchenAide was the HIGH end of appliances and really expected much better service since this is the FIFTH time the unit has failed.
