My bike has cut out while riding a few times now. It went in for a bunch of recalls they said would solve the problem. So today a month after the recalls it did it again. Anyone else having this problem?

By cuts out you mean you lose all throttle response? So when you twist the throttle nothing happens? Or does it go into a "limp mode"?

If thats the case it happened to another Ducati of mine. A 2016 Hyper, and it seems to happen to other models as well. Looks like the new V4 isnt immune this this mystery problem.

Hi dude. The engine cuts out. The bike starts to feel lumpy then cuts out. It starts back up again.

I experienced this two days ago at the track, a bunch of times and had to abort my sessions because of it. It happened during heavy throttle in 3rd and 4th gear on straights at around 10k+ RPMs. It felt like the gas was interrupted for a split second each time, like the engine was starved or gurgling, sometimes in a quick series of interrupts. It was unsettling to me and the bike (it's very much not good to have your bike unexpectedly slow down on the racing line in the fast group but thankfully I had no incidents). I know very well what traction control, wheelie control, and rev limiter interventions look and feel like and this was something different. The engine just cuts power for a split second and stutters at high RPMs.

Interestingly, this only happened on my 3rd and 6th session of the day, when I was fairly low on fuel. After I aborted the 3rd session I refilled my gas tank and turned the DQS off then on again and sessions 4 and 5 were fine. Then in Session 6, with low fuel again, on the first straight this happened so I pulled into the pits and called it a day.

My bike has all the software updates and charcoal canister removed and I took it into the shop yesterday for a fix. The tech spit balled some ideas with me and thinks it could be related to the inline valve in the vacuum line that fed the canister, or an issue with the gas tank, and is probably not an issue with the quick shifter sensor. I also don't think it's that sensor as the cut felt different from a shift cut. But we'll see. As I learn more, I'll report back with details.

Aside from this, the bike is an absolute violent, fast, wild animal on the track and I loved it in every way.

**** dude not good......
I’ve emailed the dealer and await their response. I’ve heard most panigales have suffered this problem over the years. You would think they have sorted it by now........

Had this happen to my 2018 V4S couple of times today. Any solutions to date?

Hey all,

I have the '19 corse and this happened to me after a longish ride last week. Didn't start until after I stopped at the shops for a short period, then on the way home, started to surge, throttle response sluggish. As I revved it a bit, it would cut out. Restarts every time, but within a few minutes, it would do the same again. Checked the fuel cap, had a bit of pressure so went and filled up. Full tank and still the same. Bike has 1000kms and a bit discouraged with the way it's behaving - anyone have any new news???

Cheers

Interesting. For me it happened exactly the same way - after we stopped for a break following a ~60 mile ride. At least I know it is not a 2018 model issue.

Might be a good idea if people include their build dates to better narrow down on what models are impacted by it.

I think I have seen a similar issue reported on another forum - the DQS micro switch was to blame.

Maybe disable DQS next time and see if it repeats?

Will give it a try next time it happens. Problem is in my case it's very random - couple of times per ride.

i have the 2019 base model and it happened to mine after a morning ride on my way home, 2 miles from home actually, it did it 4 times, rode a few miles under heavy traffic before it happened, maybe a heat issue?

Just got off the phone with my shop. Here's my story and my two cents. My V4 base ran like a top up until I took it in for its first service and for recall SRV-RCL-19-001 CR177 (https://static.nhtsa.gov/odi/rcl/2019/RCSB-19V382-9239.pdf). When I got it back, the tank no longer pressurized and it started running like it was starved for fuel. Sometimes it's just that the power delivery isn't consistent. Sometimes the bike stutters and cuts off like there's a fuel line blockage. The other day on the way home...the reason I took it in to the shop...it cut off 4 times in twenty miles. They can't reproduce the symptoms so Ducati has told them to tell me too bad, so sad, come pick up the bike. They (Ducati, not my shop) suggested I buy a GoPro and wear it at all times so I can video the bike behaving badly if it ever happens again. WT actual F? The service manager says there are four V4 base models in his shop right now and they're in the exact same boat as me. So long story short, I'm going to pick up my bike on Saturday morning and the only thing they've managed to do to it is put more miles on it. The recall was simply removing a small metal ball from inside the filler cap breather. Obviously, the Duc shop won't put it back in. But I'm considering replacing it of my own accord.

This is beyond frustrating.

Did this, no change. Has been for its 1K service and they were able to replicate the problem, ticket now with Ducati, just waiting on feedback

A little bit frustrating but hopefully just a matter of time until they identify the issue and resolve

Cheers

If they figure out the root cause, please share.

Any breakthroughs?

I have the same issue with my v4s : 1k miles, when bike gets hot (“normal” hot - 3/5 bars) and after I take a 5-10 min break /pit stop, bike starts chugging, feels starved for fuel intermittently. Also fuel in tank circulates / makes boiling noise even with the key off.

Above mentioned recall is done on my bike / no ball in fuel cap.

Wonder if it would be canister vapors/fuel from tank overflowing in into canister causing too rich of a mixture being sucked back into throttle bodies? Maybe the ball in the fuel cap was preventing actual fuel from entering the canister in addition to hot fumes?

My V4 "S" a Sept '18 build and it has only cut out twice on me but I have had the moments where it runs like a hairy goat and you feel it wants to stall on you so I down shift to keep the revs into the engine mainly in city traffic its going in on Monday 18th for its 12 monthly has 12,000klm on it. I run it exclusively on 98RON but have heard this is no good for the bikes can anyone enlighten me on this matter please why it is. TIA

Riding a 2019 V4R, with Akra full system. The recall work was performed at the time of pipe install. I can't say for a fact that it wasn't cutting out during break-in because i never went to 12k rpm. I do know that when I am in 3rd gear at full throttle the bike cuts out at about 11k-12k. When it does I lose all acceleration...like i bumped into the rev limiter. There is no sign on the display that that I am even near the 16.5 rev limit, with the pipe and up map. I am forced to quick shift to 4th...where I experience no issue with cutting out. It seems to be gear specific.

Thats bizarre gear specific!! mine just has had the suspension update and now wont start properly I know all the tricks waiting for the click after the fuel pump primes etc apparently others are having the same problem we have contacted Ducati waiting for a fix.
It's only when cold 1st up but blow we down today it decided to fire up straight away now I am really confused though it still backfired a few times not a really good sign.

Quick update - I'm still having the issues after an extensive stay and fault finding process with an authorised Ducati dealership, who have been excellent in their dealings with me however still waiting to get to the bottom of it...

I'm hearing a rumour of an updated map that will run a little richer allowing for better start and low rev running, will wait and see what transpires... funnily enough, surging is minimal now, more feeling like cutting out and so I rev the crap out of it and hard to start when cold but every once in a while, it just starts?!?!?!
