Like many here I took the dealer's word for it an have not changed the "lifetime" transmission fluid in my 2016 CX-5 GT. I'm at 104K and have decided I want to start doing the right thing and start changing the fluid. I have heard that if you don't do it by 80K you might end up with issues if you change it. My dealer makes you sign a waiver if you have them do a fluid change. Has anyone heard of a failure that has occurred as a result of doing a fluid change at just over 100K? If you know of an actual SkyActive transmission failure after a fluid change I'd like to hear about it.
My plan is to take it cautiously and do a simple drain and fill, then drive it a few thousand miles to see if anything goes wrong. Then probably do another drain and fill, then a few thousand more miles drain and fill, replace the filter and clean the magnet. 3 steps spaced out by some miles. From then on I'll probably just drain and fill every 30K for good measure. I figure leaving some old fluid in the system will be less of a shock to the transmission. Let me know if this seems like a reasonable (if overly cautious) approach. For my Honda's I have always done a 3x drain and fill all at one time, not knowing what previous owners may have done. It never occurred to be the transmission might fail.
