I had a similar problem with a Mazda and I suspect that all big manufacturer H/Q's are the same.
In my case the dealer damaged the paint.
Forget them resolving it as they will just pass it back to the dealers (if you ever get them to acknowledge the problem)
Forget Trading Standards as they are slow and won't put there hand in their pocket to prosecute. They will try and conflict resolve mediate.
They will after they fail offer to give you a statement for when you take out a private small claims prosecution.
I would contact Auto express, send them photos and tell them that it's not an uncommon problem
Or if you are cheeky, ring up Honda UK and purport to be following up a story for a disgrundled Honda owning Auto Express reader.
I know what I'd do.
Good luck **
