I'm sending a letter to Ducati, because this absolutely unacceptable quality control. I smell a potential recall....

My bike is at the dealer being repaired under the warranty, but never-the-less I don't want the same issue to re-occur only days or weeks later.... Thus the need to understand the true root cause.

I Ride: Ducati Panigale V4S
Thumbs down Ducati Panigale V4S Transmission Output Shaft Seal Leaking Oil AGAIN!!!

After 3 weeks of driving my new 2018 Ducati V4S off the dealer showroom floor my transmission output shaft seal started leaking oil. The bike spent 2 weeks at the dealer. They replaced the seal with a new one. After another 2 weeks the new seal failed and oil started leaking again. I have been in contact with Ducati of North America concerning this matter. I have provided them with full details including images. As of today 6/15/2019 I have to bring my bike back to the dealer to have it repaired once more. The lemon law is now going into effect. If the seal fails for a third time then Ducati must buy my bike back at the full price I paid.

This is the information I have provided to the dealership for the third seal replacement.

We’re dealing with one of three problems
  1. A defective seal, where possibly the chemical make-up of the seal is incorrect ultimately resulting in cracking or splitting under the applied conditions (friction, vibration, heat). Although, the fact that you mentioned you’ve never seen this problem before and that my bike has already destroyed two seals in 6 weeks likely means that perhaps it’s not the seal, but rather the output shaft itself. If it was a defective seal you would have likely seen this issue with other V4’s as well.
  2. The output shaft itself has a surface with defects in it, scratches, marring, roughness creating abnormal friction/heat causing seal failure.
  3. The transmission output shaft is out of round (machined incorrectly) or out of balance, either of which, would create an oscillation effect placing the seal under abnormal stresses for which it was not designed. You can test for this by removing the chain and sprocket and holding a straight edge next to the shaft while it’s spinning at different RPMs (this will test both a defect in shaft machining as well as unbalanced oscillation).

Pictures of failed seals and oil leaks
When I receive the second failed seal from the dealer I will take a photo and post.

Those who mentioned it was the output shaft itself, did the dealer have to take your entire transmission apart and replace the output shaft itself? How long did this take? Did they do a good job? Any issues after you had the new shaft installed?

PLEASE if you are having this SAME OIL leak issue PLEASE contact Jacob Trump from Ducati of North America (NA HQ)

Okay, here's the deal with the Panigale V4.. They packed so much power into this thing that the engine produces more heat than nearly any other bike on the market. The central ABS control unit is located above the engine and the manifolds, so it is subjected to a tremendous amount of heat. As such you'll notice that on the V4 your brake fluid (front and rear) turns black in about 1-2 weeks. When the fluid is subjected to such temperatures heating and cooling etc, bubbles start forming, as it cools moisture is pulled in etc. All of this combined will result in your brakes going soft. Essentially, you need to flush your brakes about every 2 months or so depending on how much you ride and what the weather is like where you live. If the bike didn't have ABS, this wouldn't be a problem.

Thumbs up PTFE Seals, an interesting fact...

The seal is not PTFE it is Viton FKM, so it does require lubrication during install. PTFE seals are installed dry.
