I've never seen physical damage covered by a warranty.
The shop that last changed your oil/oil filter should pay for the repair though since they are the guilty party that damaged the threads.
2009 Silverado 3500HD Dually, D/A, CCLB 4x4 (bought new 8/30/09)
2018 Arctic Fox 992 with an Onan 2500i "quiet" model generator

Yes! And, IME, it would have probably leaked from the moment oil pressure/volume was initially supplied by the oil pump.
The OP doesn't state which model (age/current hours/size/fuel type) of Onan generator they are speaking about which would be helpful in getting more useful information in this format.

1. I would attempt another filter. It IS possible that the new filter is wrong or has damaged threads. IF the old filter was cross threaded, then it would have leaked. ALSO, if old was cross threaded and FORCED to mate to the old housing block, it would have taken a large force with pliers to unscrew it. THAT should have alerted the existing so called tech that something was wrong and they then notify you.
2. I have almost 45 years of servicing Onans and have NEVER come across such a problem. NEVER!
3. As to your ESC, ESC's ONLY cover covered parts that BREAK, not parts that have been damaged by a service technician or customer. Doug

Thanks all for responding. I’m the only one that has ever changed the oil. And while I’m not a certified mechanic, I’m competent with basic repair. I also have always hand tightened as recommended, and I struggle to open a jar of spaghetti sauce, so I’m certain I couldn’t have over tightened it.
This is the model for those that asked:
Cummins Onan 5.5 HGJAB-1038 RV QG 5500 gasoline powered generator.
My next plan of action is to reach out to Onan directly as I’m in warranty as per years/hours.
It just seems like poor craftsmanship that a filter can cross thread the plate. ?????

I started to cross thread an oil filter one time - or rather, I tried to put the fuel filter in place of the oil filter on my Cummins. Let me tell you, it takes some real effort to even get it started - which is what kept me from continuing on and damaging it. I think THEY cross threaded it. If you can get it off, I suspect you can get the new filter on properly.

Thanks for filling in the additional information. Just because you didn't over tighten the filter, doesn't mean it wasn't cross threaded. (I've done it!) On the Onan 5.5, granted, it's difficult to cross thread the oil filter, and, it is possible to get knackered threads out of an OEM box, (returned items, factory FU's, etc.) however, IME, . . . . unlikely. That said, I'm sure there's a way to economically get beyond this, but, . . . . just not in this format. Good luck to you.
