I'm not having as much trouble with my car as I did at first, and AFAIK, it has not had an update. Sorry to hear yours is acting up.
Thoughts:
Carplay should not be wireless since it has active content (executable code). It's a security issue. If you trust Apple, sure. I don't trust Apple or Microsoft to put security ahead of profits. If they did, there would not be active content in letters and pictures.
20" rims handle very well on the I-Pace even with All Seasons and relatively narrow tires. Not my opinion, I ran it at a closed course event against gas cars. I also hit speed bumps at 25mph constantly and it's smoother than our Cadillac which is saying a lot.
I honestly have more issues with my I-Phone X than my cars. Messaging crashes, finger swipe to close apps is terribly unreliable, changes in the interface and buttons make it go mute unintentionally, terrible ATT coverage in our area (18+ million people in a 50 mile radius, <2 miles from 3 antennae yet 0-1 bar coverage), junk calls, auto-rotate image unreliable, music store and app store loaded full of misleading content, apps launch accidentally when I have it in my pocket, no USB support, no replaceable battery, no microSD support, clumsy/unreliable directory structure, vast amounts of undocumented features/quirks, unpredictable battery life (dead in 6 to 120 hours, and not sure what causes early drain), it ate $200 of music I bought during a sync with a MacBook Pro that I had to repurchase, etc, etc.
Auto infotainment is the #1 service complaint across the board. For a Year One car, I'd give the I-Pace a 5 out of 10. Keep in mind that many cars still lack Carplay and AA.
It has a lot of features, but the system is not stable. My biggest gripe with it? It doesn't have a built-in phone. WTF? All my cars since 2004 have had a phone built in. Now for the first time over a decade I have to carry a phone. Even my ZR1 had a built in phone, and it was pretty much a track car.
