BR..I just went thru this with my 11..2 full seasons on it, never ben back to the dealer..ran flawless.gas and go as you can get, last ride, last spring, with my son on a spring bear hunt, end of the day headed back to the cabin, running about 30 breaking trail down the ledge on a valley floor...all of a sudden i have flames engulf the sled...slide to a stop, jump off, whole right side is engulfed. ...start shoveling snow on the hood, reach in and rip the side panel off, keep shoveling snow in..finally get it out, pick up the peices..drag the sled the last few miles to the cabin...start looking at the damage..end up pulling all the melted wires apart, using a strap around the clutch and get the thing to fire up(couple hrs involved in this)..sled runs, idles ok..moves..so next morning..we pack up and head for the truck(this is 50 miles of rough country).sled runs crappier and crappier..but we make it out..take to the dealer..turns out it stuck an ijector..filled the motor and the exhaust with fuel...polaris warrantied the injectors, complete engine, and some electrical..said the rest wasnt covered, even though a covered part resulted in the damage...so I filed a consumer complaint with our AG...8 months later..polaris and the dealer are fixing all the damage..(7 grand total in parts, last I heard)...it pissed me off bad enough to make me walk away from the 2-13 pro 163's I ordered, and as soon as the dealer hands me the 11 it is going up for sale as well.......I am glad poo finally stepped up..but I as a consumer..riding a completely stock drivetrain(yes I do reinforce my tunnel), who bought a sled with a in writing 4 yr bumper to bumper warranty should not have to get a lawyer to get warranty repairs done for a covered failed part......so yes, I do have first hand experience on what can go wrong with your poo warranty...........
