My 900 Stampede has been the same way since day 1. It doesn’t like up or downhill parking. You have to jerk it out of park and it makes me sick to do it. It gets bound up parking on an angle and I wish they’d find a fix for it. The best thing to do is leave it in gear. If you park uphill, leave it in Drive. Downhill, reverse. That’s what I do anyway.
