I have a 2023 CForce 1000 with a whopping 507 miles on the dial and it will not shift into 4x4 or 4x4 Lock.

Anyone with any guesses?

I am out of warranty and will not let the stealer abuse me.  I twist my own wrenches.

I had that exact problem on a 2016 grizzly 700, but it was stuck in 4x4. It was the electrical servo that actuates the differential that was broken.

My 2020 Cforce450 did the same thing pretty early and I was told it was a bad electric motor or servo.... this piece. Anyway this was replaced under warranty and everything was back to working order.    Good luck with it.
