Just an FYI. I was at my local Mazda dealer, bs'ing with my parts guy after picking up a few things and he pointed to 3 2017 xfer cases on the shelf he was replacing and already had done 6 or 7 already. They overheated, puked all the oil out the breather and fried...
I've been looking all over the internet regarding this claim that 2nd gen CX-9's have this problem and can't find one complaint. I did see numerous cases regarding the first gen presumably containing Ford parts. If one dealer says he's done 6 or 7 already, that means it would be a widespread design flaw affecting most CX-9's. Yet nothing on the internet. 6 or 7 is a lot considering the low sales volumes of the CX-9.
