THE PROWLER XT 650 H1, IT IS NOT IN YOUR LIST OF VEHICLES, WAS IN NEUTRAL WITH THE EMERGENCY BRAKE ON. NOBODY WAS IN THE VEHICLE. ALL OF SUDDEN IT TOOK OFF, FAST, WENT DOWN THE DRIVEWAY AND LUCKILY STOPPED WHEN IT HIT A TREE AT FULL SPEED. THE ENGINE WAS STILL RUNNING AND WE SHUT IT OFF. GOT IT OUT OF THE TREES. THE OWNER GOT ON IT PUT IT IN REVERSE AND IT TOOK OFF AGAIN WITH ONLY 3 TIRES AND WAS UNCONTROLLABLE. IT HIT 2 VEHICLES BEFORE THE DRIVER WAS ABLE TO TURN OFF THE IGNITION. IN RESEARCHING RECALLS FOR ARTIC-CAT, I DID FIND ONE WITH A SIMILAR PROBLEM FOR ATVS. OURS IS A PROWLER. *TR
