I've had a KA sxs fridge for over 6 years now and no problems at all with the icemaker. All icemakers are potentially prone to problems - particularly freezing lines - I don't think KA is any worse than any other brand in that regard.

Our 2007 KA built-in had a problem (Nov '08) with the "flap" just inside the ice dispenser remaining open (or just not closing all the way) after it dispensed ice. The fridge was still under warranty, so we contacted KA for repair svce. We lucked out getting a local guy who owns an authorized svce co (we'd requested KA not make arrangements with A&E). The part(s) we needed was on back-order, so we had to wait awhile for it to come in, but the ice-maker was fixed in 1-2 hours.

SxS models with ice maker in the door are sometimes problematical. The door areas tend to be at a slightly higher temperature than the interior-proper (on both the freezer and refrigerator sections, thus the oft-stated advice that milk stored on a door shelf doesn't last as long). Coupled with air infiltration from the ice chute opening, ice in the storage bin may melt ever-so-slightly into a chunk, jamming the dispenser and the bin removal mechanism. Higher room temperature and humidity, such as in southern states where air conditioning may be run at 80°F contributes to the problem, as does low ice usage, infrequent "rollover" of the ice supply.
