My 2019 M5-111 (tier 4) last month had catastrophic engine failure, 1,200 hours, from the diesel high pressure fuel pump. I only use gas station diesel in 5 gallon containers used only for diesel. Cost estimated $17,000. I wonder how many other Kubotas are having this issue. KTAC, Kubota insurance is not covering the claim.

I will start collecting contact info from other Kubota owners to see if this is a systemic problem of filters not filtering and maybe hold Kubota accountable. Send your contact info to me at Landruma@aol.com if interested.

A few more details would be helpful. Was it just the fuel pump that failed, and if so how did it destroy the rest of the engine?

If there was a factory defect, you'd think it would have showed up well before 1200 hr.

Don't know about the newer engines but my L2550DT has about 6200 hours (off the top of my head) and the system has operated flawlessly, never even pulled an injector.

I do have an in-ground tank pumped through a water block filter then into the tractor tank though. Having noticed water building up in the tractor fuel filter years ago I have learned to keep the tanks full to lower condensation forming in the fuel tank of the tractor. My tractor filter remains clear (red) fuel now but I still replace it every couple years.

I don't know, Kubota dealer has not opened engine yet. Fuel pump no longer drawing fuel, guessing the timing gear damaged due to grinding noise when trying to start. Guessing fuel rail and injectors may be damaged. Lot's of guessing at the moment.

That's why it's a guesstimate. We all use our experience to get a feel before diving in. Not really here to argue about the estimate. Looking to see if this is a common failure of tier 4 engines.

I'm guessing you won't find anyone with the same failure.

My 2019 M5-111 (tier 4) last month had catastrophic engine failure at 1,200 hours

I would pursue a warranty claim before insurance. I believe the engine and drive line have a six year warranty.

Do not antagonize anyone until you pursue a warranty claim.

Unfortunately, the warranty expired 9 months back, according to dealer.
