I have this Mule bought new in 2021. It started jerking when driving over 2 mph and the engine jerked and hesitated even out of gear(like it does if you do not release the parking brake completely) I was still under warranty and it turned out to be a parking brake lever switch that went bad. The dealer said this is a common issue. The parking brake lever switch part # 27010-Y017 and grommet 92071-Y006 were replaced. I ordered another one...it's cheap and it looks like it can be bypassed if needed...a tiny little switch. There is no mention of this in the service manual anywhere. I ended up spending about 1300 bucks to buy a trailer to get the Mule to the dealer, living in nowhere land and unable to rent one. I hope this helps someone.
