I have two with about 6000 miles on each. Not a hiccup out of either.

Any part can break, even a new one. Parts supply is an issue I would imagine since they are having a tough time producing enough of these to meet demand. All the parts go into new ones.

I spoke with the service manager at the dealer where I bought both of mine. Other than oil changes, none they have sold have been back. I took that as a good sign....
