EPS Problems on 2018 Sportsman 570 SP Hunters Edition

Recommended Posts

I have a 2018 Sportsman 570 SP Hunters Edition. I bought the quad new in August of 2018 and put around 20 miles on it with no issues. In early January of this year the quad was acting as if it had a bad battery even though it had been plugged into a tender. I checked the battery and it tested well so I took it to the dealership for warranty service. They had it for almost a month. They determined the quad had a bad EPS unit and swapped it out. Then they told me that the wire for the EPS needed to be updated as they could not program the new unit with the old wire. After the wire came in dealership told me they were still having troubles programming. After another week and a half they told me that they had consulted several times with engineers from Polaris and found a workaround and that the quad was ready for pickup. I contacted Polaris to inquire about the warranty being extended as it was in the shop for a month. They extended the 6 month factory warranty for an additional 3 months. I picked the quad up and the dealership said that the 2018 SP editions were known to have issue a with the EPS units but believed that they had fixed mine. I had it back for around a month and took it out a couple times for short rides and everything seemed fine. I parked it again for a few days and when I went to start it same issues (acting like the battery is no good and won’t start, when I jump start no power steering). Took it back to dealership and waiting to hear what the diagnosis is this time as well as their plan to fix this permanently. Just wondering if anyone else has had issues similar to mine or can give me some advice. Thanks in advance!

polaris needs to get with the game lol, I know the new models have problems here and there- but what can you expect when everything is electrical?

They replaced the voltage regulator and so far it’s been working fine again. Maybe the first EPS unit fried it somehow when it went bad, Idk. I’m just hoping this is the end of my problems with it.

I hope so too. I just bought a 2018 570 sp and have been looking around at common problems in case they ever come up on mine. I have seen a few times around the web that the voltage regulator goes bad on them. Dont have much time on mine yet though so well will see how it goes. Thanks for the reply.

After replacing the starter solenoid, the "brain", and the fuel pump on my 2017 450 sp. HO I gave up and it's now gone. No eps involved.

what was it doing?

i think its hard when a company (any company) starts making a new model of atvs to get all the parts bulletproof on the first try...every model is different and polaris has to make new parts for each..  I think before long the 450, 570, 850, and 1000cc will be just as reliable as the old 400 and 500cc that were ruled the first class atvs in the world in their day....

just remember, if a product is totally garbage, no one would buy it and the manufacturer would go out of business.  the exception is with the chinese atvs that are just so dirt cheap that folks cant resist.

      Hi, I got a check engine light and a diagnostic code 520194 2 and i know it has something to do with throttle voltage out of range
      I'd like to know if thats something that can be adjusted ? Or does anybody know what should i test  ?  I just bought this atv and I'm fixing it as its been in an accident. 
      I also changed throttle leaver as original one was broken and I noticed inside the 4x4 selector assembly there are 2 contacts but I'm not sure if they're suppose to make contact at idle. I found some info online but some are saying they're suppose to touch and some say they're not. I think id depends of the year of the machine but I'm not sure. I'd really appreciate any help that i can get with this
      Thanks
