I have an LG G3 and had issues with the Bluetooth connectivity in the Chevy Cruze that was provided as a rental from the insurance company. I was not impressed with anything about the car especially the Bluetooth connectivity.
However, not being listed on the site as compatible does not mean it is incompatible. I wholly believe that the issue is not the car and is more the Lollipop software as my G3 would cut in and out on Lollipop in my 2013 Hyundai Elantra.
