Long service history/How Acura response to my lawyer for a lemon
 

If you plan on buying the MDX, read the attachment of my long service history with ongoing issues and the letter from Acura responding to my lawyer. Basically, they're saying "respectfully decline assistance", so I am stuck with it now. My first and last Acura.

Did you have to pay for any of the repairs out of pocket?

Seems like a lot of stupid issues. I think it would be my last Acura too. That said, I have had very few problems with my Acura's and I have many Acura vehicles, except the tranny issue with my 2002 TL. Acura always stepped up and did the replacement (3x), and provided a loaner.

Bummer. Unfortunately, every manufacturer pumps out a lemon every now and then.

I'm on my 14th Honda/Acura and have never had an issue with any of them.

You're not stuck with anything.
Take the lesson on the chin and trade it in or list it for private sale.
They won't lemon unless it's the same thing over and over again.

There is nothing here that qualifies as a "lemon". I'd be annoyed too but perhaps you should try a different dealer first.
