You can add Jeep to the list.
My 2014 Wrangler JK originally paired and worked perfectly with my iPhone 5s on iOS 7.
With my new iPhone 6 on iOS 8 it is able to pair no problem, but often drops calls. Also, the Bluetooth audio streaming frequently has brief audio drop-outs. That happens during streaming music/audiobooks from the Music app, as well as podcasts from both Podcasts and Overcast apps.
I've tried re-pairing the iPhone 5s, which is still on iOS 7, and that still works seamlessly with the Jeep.
