AC quirk
Several times now I've turned on the AC via the touch screen, only to look down a minute later and see that it turned off.
I turn the AC on a second time and it stays on. Not a huge deal, but a bit weird.

I never experienced any problems with the now antiquated 3 dial (fan, temperature, zone) HVAC systems that could be adjusted without ever having to look. Contemporary intelligent climate control systems are poorly designed and touch screen control makes them dangerous for driver operation. Set the system to 72F, and a bunch of temp sensors begin modulating fan speed, A/C, heater, recrculation and zone vents in baffling combinations in an effort to attain Nirvana. A Lexus I owned would set its system to internal recirculation on a hot day when initial cabin temp would be 30 degrees higher than ambient, and draw in outside air in mid-winter when ambient was 30 degrees cooler. And of course making changes required navigating through several touch screen menus. Once changed, the intelligence would override my settings within a minute. This, and the annoying pinball inspired cursor control, was princpally why I sold it.
