Bought a 2013 Polaris Ranger 400 and at 50 hours changed the oil, air filter, transmission fluid and air filter with OEM parts (paid through the nose for these). No problems. After 100 hours of granny driving, the POS just quit. I had Pocono Motorsports pick it up to see what was wrong and John (service) told me it was hydrolocked with 2 quarts of extra fluid in the oil crankcase. Pistons were scored and the cylinders were badly scored. He filed a complaint with Polaris but told them that there was only a "coffee cup" extra fluid in the crankcase. I called Polaris customer service to check on the complaint after two weeks of getting nowhere. They said that the damage was due to operator issues of undefiled oil! Jerks at customer service know only one response "operator error". Now I am faced with a bill for $5500 for just parts to fix a $9000 machine. NEVER BUY ONE OF THESE PIECES OF JUNK!!!! Do your homework. There is a reason why Polaris has an F rating with the Better Business Bureau. The web is full of descriptions where these POSs fall apart, spontaneously catch fire and otherwise just die. They are cheap machines that are cheaply built to get your money and promptly fall apart. Also, don't buy anything from Pocono Motorsports. They are a rip-off joint that lie to you to get you off their back. Even their service chief says that Polaris machines are junk but people still buy them.
