After two years owning my Streetfighter V4S I had no issues at all. What is your experience?
 
According to DNA, the overwhelming issues with the V4 are electrical/electronic related followed by keeping oil in the motor (not enough glue, bad gasket seal etc). Not any different than the last series.

Mechanically as long as the shop remembers to tighten everything, the bikes should be pretty bulletproof. The motor should be very reliable. I do like that the 99s had removable cylinders and you could change them and the piston/rings without splitting the case (nice on the single ring R motors). The V4 doesn’t use liners so if you screw up a wall, it’s coming completely apart. Great motor IMO with a lot of potential for more power. Overall, the platform so far looks fantastic and is improving through refinement.

The only problem I had was with the quickshifter not working down. The predominate problems at least reports here are with either that, the quickshifter, or the gear position sensor.

I have no where near 7k miles though.

These quick shifters takes a little to get used to …my buddies have Aprillia Tuono and 2022 BMW S1000rr and both of them have open throttle downshift but in case of Ducati you have to close the throttle and then shift down.Aprillia even lists that as a feature on their website calling it an Aprillia exclusive’Open throttle Downshifting’.After reading that I asked my S1KRR friend and he said same about his bike that it shifts down no matter open or close throttle.While upshifting do not close throttle at all …just keep increasing and keep up shifting.It’s pretty smooth after you get used to it.

That's not the problem I had at all. The QS wouldn't shift down with the throttle closed.

Had that till the very first 1000km service and never after that again. Must say I do not like the QS downshift with closed throttle... there the manual (clutch) process is faster for me...

I had the same issue, randomly. I contacted the outfit that I purchased the handheld reflash tool from and he edited the map. On mine, so far it is working fine.
 
No problems on my 2018 V4 that has seen years of commuting through rain and snow in WA between twisty and track visits and is now a track only bike that gets wrung out violently.

When I first picked it up, the tech explained he was flown out to italy and broke the motor down every individual piece. His words, "The motor will never be a problem for you dude, they are so nervous about the bike being a success that they poured most of the R&D budget into making a reliable motor. You're probably going to have electrical issues though."

He basically hit the nail on the head. Only mechanical problem(s) I've had were a blown fork seal on the Showa forks (at 11k miles) and a radiator fan seized up/was replaced within the first few weeks of ownership.
 
So, after returning from a track day at Thunderhill East, my quickshifter downshift problem has returned. Sometimes it just won't downshift. This time it caught me out at the end of a high speed straight and I couldn't get the bike slowed down enough to make the turn. I ran off into the grass, dirt, and embankment. Luckily, I didn't go down. If anyone else has had this problem and found a fix, please do share!
 
3500 spirited miles. Dead brake mastercylinder out of the box, gtg the past year. I keep it out of the rain though!
 
Yes they’re very reliable and also Ducati made the right choice by making the 1103 the base engine, that little bit of displacement means the engine isn’t working as hard at a given rpm vs a smaller engine. The only thing I’ve noticed is the only failures I’ve seen are from lack of maintenance and or hard core track use, which eventually meant the engine needed a rebuild, which is nothing new for any high-performance engine
