Purchased a 2018 Pioneer 1000 5 about three weeks ago. Its been sitting in my garage ever since while I installed a roof, windshield and mounted a couple lights (haven’t wired anything at this point, just mounted them). Today was finally nice enough to get it out so I drove it on to my trailer and headed about an hour north to play around with it at some land we own. Just before loading it on the trailer it started rather cold. Turned over more times than I thought it should but, it had been three weeks since my demo at the dealership so I didn’t think anything of it. Got to the land, backed it off the trailer and let it idle while I loaded the back with some gear. Drove it in turf mode with out the seatbelt for a good 500’. Stopped the vehicle at my destination, let it idle very rough and then it just died. Tried to start it again and it turned over very sluggishly. Tried for about three more times before I realized that the battery was not going to get the job done. Buddy of mine had a jump pack so hooked it up, started right up… Great, good to go (but clearly worried in the back of my mind as that should not happen on a brand new UTV with 2 miles on it). Put it in gear and died immediately before even getting to reverse. Again and again this happened. It would start but only with the jump pack and then immediately die when I go to put it in gear. Finally had the idea to start it in Neutral and then put it in drive which did the trick. Let it run for a minute and then took off in turf mode again. Drove it a good half a mile down a gravel road and it seemed to run fine, hitting speeds near 40 mph. Came to a stop sign, let it idle in high gear while I adjusted the windshield and it dies. Just dies. Never got it to start again. Had to go retrieve my truck and trailer and push the effing thing back onto the trailer where it currently sits. Pretty frustrated at this point. Could it be battery, shift linkage or other? One thing I want to add is that I noticed a time or two that the gear would not engage when I put it into the appropriate gear. For example, from park to reverse, it would not engage until I moved the shift lever back to park and then to reverse again. Or park to reverse (nothing) to neutral and back to reverse in order for it to work in reverse. Any thoughts would be appreciated.
