Okay so this was actually about a year or two ago, but I remember the infotainment system glitched out a lot for no discernible reason, which prevented me from accessing a lot of the controls, and I had some difficulty with the hardware controls which just felt poorly thought out from a UX standpoint.
Some of the things an owner would obviously get used to, but it felt like you were constantly struggling with it to do simple things that you don't even really notice doing in most vehicles.
The infotainment system was constantly having trouble, like freezing up or just shutting down for no apparent reason and not turning back on. I remember a lot of issues with the backup camera. Not unique for a modern car, but this one had more than its fair share of glitches. I think I had to reset it twice. It also developed an issue (sorry can't recall what it was exactly) that persisted for a day or two which spontaneously resolved itself while I was driving back to the dealership.
I want to say it had hardware AC controls (which is good), but I think I had it for three days and only figured out how to adjust it the way I wanted it on day three. I don't recall if I didn't understand that something was a button, or if a button actually had several different "modes" which weren't readily apparent, like being a combo rocker/push button. Normally these sorts of things are obvious from how the dash is deaigned, but my wife and I took three days to puzzle it out.
There were some other minor problems, but altogether it felt poorly thought out and kind of low quality, which clashed with some of the "luxury" accents my model was equipped with, like wood paneling and the lights which spelled out "WAGONEER" on the ground at night when you opened the door, which felt gimmicky. That money would have been better spent on refining the UX.
I actually don't think it was a bad drive, if you were just driving. I was just constantly frustrated trying to do anything else with it.
Thank you. Reminds me my struggle with a new cellphone about 6 or so years ago (don't remember the brand :(). Random reboots when I was using Maps (a very scary thing when you are driving in a new country), corrupted memory card and lost images, random freezing. Call quality was ok, pictures were so-so, but it is just like you said - things around main function - that's what makes or breaks the experience. On paper the phone looked really good, but the experience as whole was awful. Got back from the trip, returned phone back to Costco...
