I was only stating that I wasn't interested in it to preface the reason that I don't know if they have any videos or other official Honda adverts stating that the bed will dump. It isn't something that I personally have researched. But if it was, I would have researched it.
I intentionally sounded like a corporate defense atty because that is what they will tell you (and likely win). I have been involved in several "lemon law" cases in the automotive world, specifically NVH related. (Noise, Vibration and Harmonics, although there is debate about what the H really stands for
) There are some legitimate implied warranty claims on lemon law litigation, but having a feature that doesn't work the way a person expects it to, isn't normally applicable. If the bed will dump, it can be called a dump bed. I have a manual dump cart. It doesn't always dump. Often I have to lift up on the back of it to give it some "help". It is still a dump cart. I just isn't an automatic or powered dump cart. If the Honda were called a powered dump bed and it couldn't lift the specified load, then yes, it would be a good claim.
You are using a logical fallacy to make your argument what is called in logic circles as a "false equivalency".
False equivalence - Wikipedia, the free encyclopedia
For example, a windshield wiper by definition and expectation should wipe a window, that is it. If it doesn't do that, it is defective and would be a warranty claim. If, however, it is not a
powered wiper, it won't do it without manual input, claiming that it is defective, is not a supportable claim. (See what I did there?)
You tactic should be to show that Honda or your dealer gave you the false impression that the bed would dump without manual input. If you can find a video or communication that shows the bed dumping a significant load without any assistance, then I think you would have a case. Otherwise, I don't think you will get much traction.
