P1000m5 Engine problems with nearly-new 2016 1000-5 dlx

Any update?

Sorry for the silence. The other week I trailered it back down the mountains to a Honda dealer to have them do the three free service bulletins on the SxS (clutch, muffler and seat heat shield). I asked them to look into the stalling issue at the same time. The tech there was guessing that it was the fuel injector connector crimp quality issue, but I'm a little skeptical considering how tightly coupled the problem is to the motor heating up.

They were very backlogged in their service work so they just started on it yesterday and I hope to pick it up later today and take it back up to the property. I'll let everyone know the outcome as soon as I know myself.

I just read your post. I haven’t been on here for almost a year. When I read your post it sounded like the exact same problem I experienced a year ago. I was skeptical like you and was worried the shop would be able to diagnose the problem. Within thirty minutes they told me the same thing they told you about that injectors wire being crimped too tight. They said they’ve replaced 8 wiring harnesses due to the manufacturing over crimping those wires. They waited for Honda rep who said the had some “pig tail fix” instead of replacing the entire wiring harness. The Honda rep said it wasn’t going to be “approved” in time. So they replaced the entire harness and I’ve never had a problem since. It had about 1100 miles when that happen and now I have 3500 miles. Hope it doesn’t take them long and you get it back with no future problem. Good luck.

Was this only a problem on 2016? I have a 2017 which’s is out of warranty but has only 500 miles on it. It’s been rock solid so far. Hope it doesn’t gain any gremlins as the miles rack up.

Sorry to not follow up on this sooner. I wanted to spend some time with the machine before declaring that my problems were solved. So far I haven't had any issues after taking it to a dealer. Here is what they (and I) did:

• replace injector wiring
• perform clutch TSB upgrade
• perform heat shield TSB upgrades (seat and muffler)
• flush lubricants from diffs several times as water was found in there (makes me wonder if previous owner had swamped the thing)
• new fuel

Since then it has been running great with no issues. Another real test will come in Spring / Summer when the snow melts and we will see how it runs in similar conditions to when I first had these issues, but I suspect it will not.

Pretty common issue on the 2016's. I think I was one of the first on the forum to experience it. I have a thread going with some pics, diagnostics etc.

You should have a pretty solid machine now!

Fuel rear fuel injector wiring harness crimp problem. Had this problem with my '16 1K-5. Saw the other instances of it occurring on the forum. Had to go to dealer for accelerator recall anyway so I had them "diagnose" the problem. I sent along a copy of the forum pages and pics. I explained the code(one long and three short) to the service writer and he just kinda tried to blow me off. After my machine went in the shop the service writer called me back as asked and said MY diagnosis was right and the repair would be $160 and change. Fine with me. They repaired it, it runs like a brand new machine(if not better) and I am satisfied.

Initially i thought the same. Seatbelt.
He said stalled out, seatbelt just cuts power.

One of the fuel injector wires / plug needs replaced?
