Had to take our Ace in for service again. This time the brake pressure sensor switch went bad and wasn't allowing it turn over every time you pushed the brake in to start it. We came home from riding Saturday and I washed both atv's off and put them in the garage and came out the next morning and nothing...wouldn't turn over. It was 10 degree's outside so I turned on the heater in the garage for about 2 hours and came out and it started fine. I let it warm up and took a short ride around the neighborhood and came back and put it back in the garage and thought everything would be fine. I got up the next morning and the same thing, wouldn't turn over. I took it into dealer that day and they found that water was frozen in the sensor and wire clip so they dried it out and put grease around it and said it was ok. Drove home, got in it to pull it off the trailer and same thing, wouldn't turn over. Drove it right back to dealer pushed it off the trailer and said don't call me until you are sure you have it fixed. Called me yesterday and said it was the sensor and Polaris is going to ship a new one to them. They said all problems are reported to Polaris and they look at them and decide if there is a need for a recall on that issue. I sure think they need to put a rubber boot over the wire and sensor to stop water from getting into those parts and freezing. Hope the down time won't be long since most of any parts are not available for it. Guess this is what we go through when the first model comes out.
