I had bought the old model in May 2022.  The first week of June 2023, I opened my freezer to find blue liquid leaking out of the freezer bowl.  I called Kitchen Aid service and their customer service representative was so helpful, immediately said they would honor my 1 year warranty.  I was sent a new and very much improved model which was received in about a week, a shipping label to return the defective model and a new 1 year warranty for the new model!  Now that’s real service!  I have used the new model and really like the improvements to the dasher design-much easier to scrape off the ice cream.  The driver assembly to attach to the mixer head is much more stable as well.  Made a batch of vanilla ice cream and it came together much faster than the old one.  Old model -20 to 25 minutes of churning; new model-15 minutes!  Great product!
