First, let me say that I have owned a series 5000 Vitamix since 2005, and I consider the Vitamix the best blender. At least for the engine. In March 2019, I replaced the original container, since after 14 years of usage it looked pretty old. After using the 'new' container for 4 years, and an average of 3 to 4 times a week, this morning I wanted to make an iced coffee. I added cold brew, a handful of ice, and a scoop of ice cream to the container, and turned the engine on low as usual. As I was increasing the blade speed, the container suddenly cracked sending liquid all over the kitchen. Luckily I jumped back, as a sharp-edge 2-inch plastic piece flew toward me. I am adding photos for better understanding. I cannot come up with an explanation, other than perhaps a small crack that I had not noticed? I have always taken good care of my Vitamix or else I wouldn't still have one that was purchased in 2005, and I have never washed my container in a dishwasher. What type of plastic quality are the recent containers made of? This was incredibly disappointing.

My jar broke - grinding an herb. Sharp plastic triangle came at me, thank goodness no harm. Replacement is very expensive, others have commented same re: durability, breakage and replacement cost.

I bought my Vitamix 5200 a month ago. I’m happy with it but haven’t tried all the different things you can make like soup, etc etc I use it mostly for my morning juices and smoothies. Unfortunately the plastic container got stains from the turmeric I used for my smoothie I am pretty upset because I have been using it and rinsing it right away as recommended with warm water and few drops of soap and let it run for 1 min. It didn’t get clean and now I have orange stains on a nice new container. I think a glass container will be more appropriate so we can wash the food away without staining and also the need to replace it after it gets foggy and stained. I might call the customer service and see what they can do about it. It is still under warranty after all.
