Try the speed sensor

Sorry to hear your new can am is acting like that, what a bummer. That's an interesting set of issues and not an obvious common denominator that would point to the problem. Since it's new I would suspect like you did that something just came unplugged and hopefully an easy fix. Since your speedometer is an obvious problem might start with the Vehicle speed sensor. If it came unplugged or quit working it might cause this. It's located in the rear on top of the gear box behind the plate right above your trailer hitch area. While back there I would also check the fluid level in your gearcase. It's the plastic dipstick towards the back of the motor on the passenger side that takes a socket to unscrew. It's possible they forgot to fill it up. if so that would be bad. Your speedometer could also be a bad display, bad ecm, or corrupted software in the ecm. The jumping and low rpm sounds like cam shaft timing issue, maybe this points back to the ecm being bad or corrupted. The "wrong gear" is the belt protection part of the computer telling you you're damaging your belt. I'm not sure what the computer take it's que to display that message. Maybe it's throttle position and speed to see if your putting too much torque on the belt, so the speedometer might be causing that message. Given all these things and and the fact that your not getting a check engine light, I'd lean toward a bad ecm or software. I assume your taking it back to the dealer to fix. Let us know what you find out.
Did you ever find out what was going on? I have the exact same issue right now!

On our defender I found that the speed sensor and angle sensor had gone bad. Once I replaced both of them everything went back to normal and it is running fine again. Thank you to everyone for your quick responses they definitely pointed me in the right direction.
