good car, software and user experience stand to be improved
The vehicle feels and drives great.
Nice torque, roomy interior, excellent sound system, ok controls, ok hvac. 
However there are some software improvements without which the user experience is lacking.
The biggest complaint is that the i-break setting keeps being 'forgotten' every time the car goes in reverse or driving mode changes or vehicle gets turned off and on.
Every time I get into my vehicle I have to remember to flip the lever, otherwise the car doesn't drive like I expect. It's very annoying
The regen-breaking level will stay 'remembered' when vehicle gets turned off and on, but not if I switch drive modes to snow and back to regular.
Also, after I turn off the car, my mode gets reset to Normal, even if I prefer to drive in Sport.
Why aren't my preferred i-pedal/regen/drive-mode settings remembered under the driver profile?
Second complaint is that there is no way to turn the car on/off from remote. I have to remember to hit the off button.
Tesla makes it really easy where you walk away and car turns off, windows close, doors lock. On ioniq I have to do each of these things manually, and in correct order.
If I turn the car off and start opening the door, the windows stop closing. That's crazy. I have to climb back into the car, turn the car on, just to close windows, then turn off again. That's crazy.
Why isn't there a remote button that will just turn everything off and close windows and lock doors?
The passive artificial sound that the vehicle makes while driving is annoying, and there are no user settings to change it's pitch or volume.
I have to turn on the radio just so that I don't have to hear it.
The connection to the phone is mostly good, but once in a while it will randomly switch out of my phone call to music and then back to phone call and then back to music. It's weird, but doesn't happen consistently.
The other werid thing is that the infotainement system doesn't display what song is currently playing, just what radio station is playing. You have to click on the song to see a popup with the song/band titles, but that popup blocks the rest of the information on the display.
