We own a 2020 Kubota RTV-XG-850, with only 400 hours on it and it has been at the dealer 3+ months. We were just informed our engine failed and requires a complete rebuild at only 400 hours! There is a loss of compression in cylinder #1, which is causing backfiring and a loss of power. There is also excess gas in the engine oil.
We are just outside of the manufacture's warranty period, and they are serving us a nearly $5000 repair bill, with only a 90 day warranty.
A member at a different forum had the same issue at 22 hours and fortunately, his RTV is under warranty. He was informed that "short tripping" (as Kubota describes it) causes gasoline to enter into the engine oil, which causes a dilution of engine oil and eventually leads to catastrophic engine failure. This killed our engine in under 400 hours!
Is anyone else with a 2018-2022 XG-850 running into similar issues?

Bought a used 4x4, engine runs. Tried rebuilding both pulleys. Ended up buying a transmission pulley system. The new one is aftermarket. The old one wallowed out and fell off.
The new one seems not to have enough splines inside. Seems like it is freewheeling. When it revs up and gets smaller pulley diameter, does it jump on the spline shaft? The driver pulley on the engine gets larger when it revs up. Had to make a pvc collar for the belt to sit on in the grove. No parts for sale on this pulley. Is the belt supposed to sit at the bottom? There must be a trick to get the belt on. Any ideas?
Thanks Dave in Florida

The EFI light starting flashing (fast, every second) on my ‘21’ zforce 500. Still starts and runs fine. Pump still kicks on strong when starting. Battery is nice and strong. Can’t get any codes on my code reader, just comes up ‘error’. Don’t want to bring it to the dealer but not that familiar with EFI on this stuff… any ideas or suggestions would be appreciated. Thank you!
