May Passengers Legally Record Drivers in Secret? What about in Arizona?

I believe, but am not certain, that a passenger of mine recorded me when asking me what I was drinking.

I told him I was drinking a latte. He clearly could see it was out of a disposable Starbucks to-go-cup with lid. I took a sip & yawned one time. He asked me if I were about to go to sleep on him. I replied, "No." I think I probably added something extra, like, "it's my afternoon slump. I have a cup of coffee and I'm good to go." 

About 2 hours later, Uber deactivated me for life stating I was D.U.I. I texted back immediately and they said I broke the community guidelines because I was D.U.I Drowsy. I think it is extreme of Uber and this particular passenger to believe I was D.U.I (drowsy) when, clearly, this passenger did not exit my car before the scheduled drop off. Clearly, he did not fear for his safety. I believe that my passenger purposefully baited me in order to get something out of the event, say for example, a power trip, ego boost, or reduced fare. 

After his drop off, I had 3 additional trips, all without incident, prior to my being deactivated. 

If my passenger recorded me, as I suspect he did, then he did so without my permission. Is that legal, to record me without my permission? Is it legal in the State of Arizona? 

My car is my private property. He never told me he was recording. Is this legal? 

Please advise. Thank you.
