I have many recordings but they're useless because the mic pics up everything so road, wind and engine noise all blend together. Also the mic doesn't pick up vibrations so no help there.
You will feel and hear none of this in your '15 just as it was not present on my '14. This issue is present solely I believe, on the '17 Mirage CVT's with new programming, redesigned exhaust with no flex joint and stiffer engine mounts.
Ichobod,
Did your car sit for a long time or anything prior to the issue? The only thing that should cause vibrations or pulsing on a dealership lot new vehicle is rusted calipers. From a few of your other posts i gather your wise enough that's not the case.
If your not getting resolve i would open a case with mitsubishi international. There's info on how to do so in your owners manual, or atleast the PDF version EGGMAN is capable of delivering.
I think that's good advice.Quote:

An internet search should help someone find a copy of their owner's manual. However, I recommend creating an account with the Mitsubishi Motor's website in their market area (North America, Canada, Philippines, et. al.) and downloading a copy directly from them. That way an owner is assured of having the most accurate version, right from the source. And having registered with Mitsubishi might make it easier to resolve problems.
Since you've owned both a '14 & a '17 what changed in the CVT programming? If I understand correctly the '17's exhaust manifold and the catalytic converter are one piece where in the '14-'15 it was separated by a flexible exhaust connector correct?Quote:

Tech told me they had so many warranty issues with flex joint Mitsu engineered it out for economics.Quote:

I have thought that myself because sometimes I can feel it in my ears like when you open the windows too far at speed.Quote:

Just fyi the entire exhaust system doesn't just hang right off the header. The header/cat combo has a bracket welded to the bottom of it which bolts to the engine cradle sub assembly. Just behind that is a ball/socket joint. The rest of the one piece welded exhaust joins here.
