All of this can be confusing. Using 15w40 oil in a bike rated for 10w40 can technically void a warranty. The dealer or manufacturer can claim that the oil caused, or contributed to the failure. It will then be upon you to show otherwise. That is a bad place to be. Having a hitch in itself is no cause for voiding a warranty. You may have been using it for a cargo carrying rack. If they start asking allot of questions when trying to determine cause for failure, then watch out, someone is looking for a reason to get out of warranting the repair. Honda, or any manufacturer will generally honor whatever the service manager decides to cover. Transmissions without heel-toe shifters, or hitches fail. Engines with the manufacturer recommended oil fail. I now have 11K on my 2012. I have done oil changes at the recommended interval. My engine has a quite loud washing machine noise. I will have to produce records showing maintenance with the correct consumables, within the correct time frame, when making a claim under the warranty guidelines. The key word is guidelines. It would be unreasonable to void a warranty because you went 4100 miles between recommended oil changes, instead of 4000 miles.
Just my .02 cents.
I would remove any aftermarket accessory effecting the failed component, before bringing the bike in for a potential warranty repair.
