I just got off the phone with Acura.
They are now acknowledging the problem and have admitted, the system is "overwhelmed" by Apple Car Play and can't handle it. They say the "fix" is imminent and will be released, prior to the end of the summer. Once it's released (assuming it works), they will then discussion "compensation".
One other little quirk they told me about, I'm not sure I believe: The system is not just sensitive to Apple Play. I haven't used Apply Play in 2 weeks and the system still froze up on me twice, on Sunday. Acura is recommending not using Apple Play and performing a "hard reset", to clear out any previous Apple Play information in the system (which is what they're claiming caused my system to freeze).. I'm not sure I buy that story, but that's what I was told.
Over the last 2 weeks, my RDX has simply "shut off" 4 times, while driving down the road. I doubt that's related too the Infotainment system, but it's pretty odd and more than a little disconcerting.
