Purchased 2013 Polaris 500 Ranger last week. No engine brake at idle just like in a previous post. Also, just before the freewheeling starts, there is a high pitched whining noise in the differential/tranny area like raw metal rubbing. Called dealer, was advised this is normal. If I had been aware of this problem prior to purchase, there would have been no purchase, this thing seems unsafe. If you release the accelerator on a steep hill the machine will slow down then as the engine reaches idle speed rpm's, the unit makes a screaching sound and goes into freewheeling requiring immediate and hard braking. Anyone out there having the same problem and is there a solution? Thanks
