Trying to get an engineering design issue or alteration through customer service is like asking a pig to sing.
I'd suggest you start a file at the NHTSA. That might get their attention.
Similar story: I awoke from an afternoon nap hearing someone/something hammering on my house. It sounded like a hammer hitting my plumbing. I went outside to find a gas company lackey pounding on the active piping connections on my meter. When asked why, she responded that they looked rusty. I forthwith threw her off the property threatening police action if she ever came back.
I called the gas company customer service and not only were they disinterested but told me the meter was theirs and they could do anything they wanted with it. A referral to a supervisor got me some sympathy but no call back to say what had been done with that employee or if any hammers had been removed from tool boxes. I checked the meter for leaks and there were none. Good thing, as the service tech that was supposed to look over the situation never showed.
I guess in both these cases, they are just waiting for something bad to happen before reacting.
