Why would you help them out with pics if they aren't prepared to help you ?
One: to help them to not do this to the next guy.
Two: because if it is a manufacturing defect they should come clean and help the customer out even if its outside of warranty.
I’ve used to be the guy in charge of product quality and failure analysis for a division of a large automotive company. I loved getting stuff like this back as it helped us improve our products and reduce complaints and warranty costs. It would not be unusual for us to do something nice for a customer if the product was marginal but the warranty was up.
I once saw a customer receive a new set of camshafts and followers for an engine that was a decade out of warranty. The mileage was exceptionally low and the motorcycle very clean. The cams were soft, a manufacturing defect, so the manufacturer
gave the customer all of the required parts when they caught wind of the issue from the dealer.
Some manufacturers really do stand solidly behind their products.
Others do not... not to mention any names... Kawasaki...
