    I am sure you are hyper-sensitive to vibrations now. I know I would be.

    Sounds like it's all worked out for the best.

    Are you relieved/grateful they took action or pissed that it took them this long to listen to you? Or both??

    Relief overrides most of the hard feelings.
    I just wanted to love driving the car again.
    I am sorry I had to resort to such aggression to bring Mitsu and dealer to action. It shouldn't have been necessary.
    Will weld for beer.

    Here's a link to the video clip of rubber exhaust hangar "rattling"..
    Not sure if this is contributing to the issue I've been having but it is something I've not seen b4.

    I strongly doubt these thoughts factored in Mitsubishi's decision, but rather it had to be some cost-saving measure.
    I remember when gas approached $5 a gallon there was a rash of people with electric drills stealing gas from cars. Rather than siphon it they simply drilled a hole in the bottom of the plastic gas tank. If people will do that to get $50 worth of gas I imagine they'll go to more lengths to nab a cat converter that can be sold on for $150-200. Maybe theft in other countries was the reason.

    I'm curious about the Mirage failures in the PQ fleet cars.

    Didn't the 2017s get a different motor mount?

    Because I wonder if this could contribute to the vibrations Ichabod Crane is experiencing. Though the new mount may soften harmonics for most motor RPM and load conditions, it could make certain situations worse.

    This reminds me of the car I drove before Speck. That was a 2007 Ford Focus wagon. When I took it for a test drive, it had a harsh vibration through most of it's operating range. Replacing a single failed motor mount solved the vibration problem. But that motor mount was known to be failure prone. If I remember correctly, it was liquid filled.
