I have mine since three weeks and it was down 90% of the time. Throttle wire froze in water that got into the cable. Parking brake also froze and the wire became corked and had to be replaced. Even after that it will not start rolling because a security switch somewhere shuts every thing off wen I step on the forward pedal.
This problem seems to be related to cold (sub freezing temps.).
I am very disappointed and will try to get my money back.
On an other subject, where did you get your cabin? My dealer says they are not available.
