Had to have the strike plates adjusted on the rear doors, they stuck out just enough to make you think the doors weren't shut all the way. I kept blaming my poor kids for not shutting them. Check your doors, it's a quick fix.
No, they close with normal force, and no dummy lights appear on the dash. I noticed it while washing and ran my hand across the seam. It looked just like the door was not closed. I took it to the dealer and the regional service manager for Houston happened to be there. He took note of the issue and the fix in case any more mdx came in for the same problem.
