I had the same issue happen to me on my 2017 Chieftain. It started to kick into safe mode and deactivated the rear cylinder. The first few times it would reset when I would shut down, then restart. After a few times of that, it wouldn't reset anymore. Dealer replaced the throttle body. Fixed the issue.

 

There has been some updates done in the latest ecm flash, maybe have the dealer check yours out. My buddy had his in for a few issues and they re flashed his ecm saying there were some updates.

 

I just bought the Challenger on March 19, and was told by my the dealer that they always update any ECM and VCM flashes that need to be updated. The bike was just in for the 2500 mile service last week too. That being said, I'm going to call them today and ask if that was done on my bike.

Regardless of whether or not the ECM needs to be re-flashed, if shutting the rear cylinder deactivation off solves the problem, it's going to stay off.

 

Not having that issue on my 2020RM with cylinder deactivation.

 

If it's able to be, just switch it off. I can't think of an actual reason for it besides people being used to it by coming from over sized air cooled engines that needed that engineering band aid...
It's absolutely unecsessary on liquid cooled bikes..

 

Wow! I didn't know you are an engineer

 

Yes, my base model stalled or shut off a few times in the exact same manor while coming to a stop. This was when it had under 500 miles on it, I mentioned it when i took it in for the initial 500 check up.The dealership said my throttle body was within specs so that was not an issue. Mine has not done it since and I'm at 4000 miles. I will take your advice and shut down the RCD if it happens again.

 

Never heard of the issue till now ?

 

Before i took mine in to have Throttle Body check and ECU Reflash mine died three times pulling up to a stop sign. After ECU Reflash at 4k miles never happened again. Now at 8,200 miles. Also before Reflash ever now and then would get irregular idle. But none of that since reflash.
Also should mention that the three time it died engine temp was at 180. RCD doesn’t engage on mine til 185.

 

I've been having an issue with a noise from the engine everything I twisted the throttle on my 21 Challenger, shop had it for 3 weeks and couldn't find the source. Nothing from Polaris either. They gave me the bike back and said ride it till it gets worse. Mind you the bike ran perfect just that weird noise. I turned off the cylinder deactivation and boom noise is gone. So I think there's definitely something going on with the components of that feature causing problems.

 

My 21 shut off at a stop sign yesterday morning. Has just 1000 miles on it. Started right back up but WTF? A brand new $26k bike just shuts off and the dealer says, huh.....I can file an ask form.....smh

 

I haven't had it happen but very rarely. Usually shortly after start-up so maybe I didn't let the engine warm up enough. Other than that the clutch engagement friction zone can be a bit abrupt and I have stalled the engine occasionally taking off from a stop. Never had the engine just up and die like others have reported.

 

It’s happened a handful of times on me. Always when pulling in the clutch as I roll to a stop sign. Pretty good at starting it the second it happens. I don’t consider it a deal breaker

I agree but this kind of nonsense should not happen on a brand new machine I just laid out $25K cash to purchase

 

Due to my choppy idle I am unable to engage cylinder deactivation on my 21 challenger without fear of stalling at stops intermittently it's at the dealer for the 4th time, it's October, missed over a month of riding this summer, Bluetooth cuts in and out.... My 17 Chieftain was a solid bike and I'm seriously considering dumping this bike because Indian dealer is 69 miles away and I'm tired of their inability to get this machine running properly 😒

 

Yeah I am pretty disgusted at this point. The dealer where I purchased mine doesnt have any "qualified" techs and while they are nice people, they have a "I can only do what Indian tells me to" mentality and I am sick of taking the bike in to have them plug it in and tell me there's nothing they can do.

 

From my personal experiences with my own Challenger.. I have noticed three things that have contributed to my stalling.. one was throttle lag (which can be easily addressed with an ECU flash from Dynojet or Lloydz) and two, cable clutch adjustment. Sometimes the cable slack is enough to trick the bike into thinking it is still in gear when slowing down, so when you let off a bit, it shuts down. Tighten it a bit and you should see an improvement. One way to check is starting the bike in 1st gear with side stand up. If it doesn't start, you have too much slack. and three, rear cylinder deactivation. Don't think it's really needed for these bikes. I keep it off all the time.

 

Remember the Challenger is a new bike introduced just over a year ago. I think most of them are still in the learning stages on how to address these bugs, compared to Harley who has been servicing the same bike technology for years.

 

I know but come on.....Loyd's figured it out. Why can't whomever wrote the programing for Indian do the same?

 

I bet they are working on it.. i'm sure they have eyes on everything that's going on with their bikes including taking a look at the Lloydz and Dynojet ECU flashes.

 

My Challenger died twice with the cylinder deactivation on and has died twice with it off. After it died the first two times, I took it to the shop and they discovered the throttle body sync was way out of spec. Everything was fine for thousands of miles and then one day it died as I was coming to a stop (just like you described). A few weeks later, the same thing happened again. I spoke to an IM tech that is very knowledgeable and he suggested I conduct the throttle relearn procedure, which I did. Havent had a problem in the last 3,000 miles, so hopefully I’m good to go. Also, the IM tech told me to leave the cylinder deactivation off. Here is how the tech told me to reset the throttle:

 

I'm not following this one.. (although I have slightly different steps on my personal notes)

Let me know if I am interpreting this accurately.

• engine kill switch in on position
• press ignition power button on
• wait 30 secs
• turn power button off
• wait 3 min

The last part is confusing...

• start bike and let it run for 3min? or
• press power button and kill switch on, to let fan cycle, then turn off for 3min.

 

got it.. not related but the only time I ever received a cylinder 2 misfire and check engine light was when I put bad gas from the local BJs club. When I took it to the dealer they mentioned bad gas and I didn't believe them.. That same week, my new GMC denali pickup truck got the same check engine/msg.. and got gas from the same place. So I knew there was a connection.
I drained the gas on the bike and put fresh gas from another station and the issue went away. The truck had too much gas so I just drove it till I was able to add fresh gas, and that issue went away.. just my personal experience. Good luck to you. Hope they figure it out.

 

I have had this suggested and I did fill up at various stations. Nothing changed.

 

great. sounds like you're covering all angles. hope it works out. keep us posted..

 

Report it to Polaris so they know to look into it.

 

Mine has always been on. We put 5000 miles on it last year, It did die twice just like you described. It worried me when it did it, but started right up and ran fine.

 

RCD works fine. If you brake moderately and are getting low on fuel the uptake can become unported briefly.

 

My 21 did this engine shutting down thing while coming to a stop 3 times this year. Dont use the rear cylinder deactivation and no codes ever showed up but I did just have the parasitic battery draw flash done last week and he noticed I hadnt had the latest firmware (or something) update in RC so he did that as well. Fixed the throttle lag and surging issue and no more battery drain. Still have no idea why the engine was shutting down......

 

There was an ECU update earlier this year to change the drive by wire mapping and fueling at low speed and misfire detection. Most likely what the tech was talking about
