KitchenAid review: KRMF706ESS01 Kitchenaid refrigerator

We purchased a Kitchenaid 5 door stainless steel refrigerator model#krmf706ess and paid almost $4000.00 in June of 2017. The ice maker and water dispenser has never worked properly and has always leaked water. Then after only 5 years ice started accumulating over the back of the fridge and the fridge stopped cooking. We called a repair man and he replaced the parts per a repair that was in his computer because this has been a problem with other refrigerators. Replaced evaporator fan and some other parts. He said fan stops working then ice builds up which stops fridge from cooling properly. Then the drawers on the front of fridge stopped working. Then after 6 months of being fixed ice started building up on back of fridge again and we started having the exact same problem all over again. Repair man came out and said he would have to replace the same parts again and suggested we just get a new fridge because these fridges are basically money pits. This should not being happened and a 7 year old fridge that was $4000.00! I have read that this is a problem with these fridges.
