I don't own one but from the fleet of 30 something Mirage's we've had 3 that needed replacement. One at 304k kms, one at 223k kms and one that still worked fine but make a weird noise was replaced under warranty around 89k kms. We had another car that was having some issues, I don't know many details but after a fluid change from the dealer it seems to be ok again?
The highest mileage cvt we have with the original cvt has 261800kms in a 2015.The next highest 15's have 202k,199k,197k. For the 17's we've got 3 with almost 170k kms and they weren't easy one's I'm sure.
Off topic, the obd gps' we used weren't cheap but the seller probably bought a sea can of em and is making a killing. They worked great in all of the 70 or so vehicles I've put them in with zero problems except the finiky Mirage.
