    Question Noticing a faint squeaking upon acceleration while in drive.

    Hello everyone,

    I'm posting here because I suspect that my CVT has a failing bearing somewhere. My 2018 ES has just over 32,000 miles on it and is still covered under the manufacturer's warranty. (60k warranty since I got it used at 15,000 miles) Everything is working perfectly normal on my Mirage, but I have recently noticed a faint squeaking noise when I am accelerating. The noise goes away if I give it a lot of gas or let off entirely. It is also only audible in drive and reverse. I can not hear anything in Ds mode, but that could be due to the car being at obnoxiously loud, high RPMs. Does anybody know if this is a common issue or totally normal sound with the Jatco transmission they put into the 2018 model year? I know how expensive CVTs can be to replace, and I definitely didn't purchase a Mirage to own a money pit. I love this little thing so far, and I only want what is best for it.

    All this being said, what would my best course of action be to preserve the longevity of my car? Assuming I did return to the dealership for inspection, what repairs would a faulty CVT bearing entail? Again, I am supposed to be under warranty until 60k miles.

    I do apologize for my first post being a maintenance question, but I really need sound advice from those with Mirage experience.

    Thank you.

    Hello 3_Cyl_DeVille and welcome to the forum.

    Troubleshooting over the internet is difficult because we can't see or hear what's going on. However, the symptoms you describe remind me of something another forum member shared here, whose problem was found to be an exhaust hanger that was loose and noisy at certain conditions.

    Unacceptable vibration/rattle @ 13,000 km SOLVED: loose exhaust hanger

    If you are able, start with simple stuff first before concluding your CVT is on it's way out - crawl underneath and check your exhaust hangers.

    We've also had members report their intake air snorkel was becoming loose and noisy. Check that too.


    We are lucky to have more than a few forum members with experience working on our favorite little cars. Stick around and I suspect you'll get lots of good advice and pointers about how to get the best out of your Mirage.

    Thanks for making a forum Garage entry. It helps others know what you have and how it's configured. You'll have to let us know more about how you decided to get a Mirage and how you came to our forum.

    Could this be the exhaust flange 'chirp' that appeared when Mitsubishi changed the catalytic converter for 2017?

    My first thought is what eggman already posted. The 2 rearmost rubber exhaust hangers wear out on the body side. Quick test is pull the rubber off and put a few wraps of duct or electrical tape on the metal rod and put the rubber back on. They changed the exhaust setup for 2017 and this is the result.
    The other possibility is a loose belt, but they usually chirp under hard throttle where the loose exhaust hanger would do it under light load/acceleration.

    If you want to keep your cvt lasting I'd recommend replacing the fluid at 30k miles. I used to say just pull the plug which is usually good enough and you'll get about 2 1/2 quarts/liters out. Jack up the back of the car and get almost another 1/2 quart. With our cars at work being used for work we need to follow the severe schedule and when we had a warranty issue with one the dealer claimed pulling the plug isn't good enough and had to provide proof of dropping the pan among other non-existent impossible things like a transmission flush regardless of what the factory service manual says.
    Regardless it's not a bad idea to drop the pan and look for bit's o' bearing and change both filters. With really high mileage over 200k miles start looking for low mileage used one cause the odds are against you.
