Problems with 2-year-old VitaMix machine

Question

I have the vitamix model 5000, that I purchased about 2 years ago, gets used moderately- about 3-4 times a week, and no more than twice a day. Usually I make smoothies, or other frozen mixtures (rarely hot ones)

Recently the motor has been starting and stopping, when I make smoothies with ice, and the VAR/HIGH switch is very sticky. This results in an abnormal amount of chunks of ice in the finished smoothie.

I have not changed the ingredients, or the way I put them in the machine, so I am inclined to believe that the motor or blades are failing, but why? It has a 7 year warranty. Anyone else experience these problems?
