1. Stay in previous driving mode on restart
We all know why this will never happen. Fuel economy is already poor enough and KIA (like most manufacturers these days) used ECO or COMFORT mode feature to gain a bit extra in EPA ratings. Hyundai has already paid dearly for their fuel economy lying scandal...
2. One paddle switches to FULL manual mode and changes gear appropriately
Already switches to manual with one paddle. Whether it stays there depends on driving mode, which is sensible.
3. Both paddles switch to FULL manual mode but stay in current gear
Sure this could be programmed to trigger transmission sport mode, but a bit unlikely given that it's a bit fidly and most people wouldn't remember it.
4. In manual mode, bounce off the rev limiter, beep, but DO NOT SHIFT UP!
Agree!
5. In manual mode, if a downshift would over-rev the engine, don't shift (stock functionality) but beep to inform driver
Agree!
6. In manual mode, do not switch out of manual mode at a stop. If I'm too stupid to shift to first gear, I deserve pathetic acceleration.
It doesn't if you are in sport mode (with the latest ECU/TCU software).
7. Engine auto-stop should only default on in ECO mode, but state should be remembered for other modes
Won't happen for exactly the same reason as #1
8. A Sport+ mode is needed for the suspension, especially the wallowing rear
Agree. Three settings would be ideal. We also need four (one additional) settings for the transmission. The current Sport could be re-named Sport+ and one in between current Sport and Comfort added that isn't so aggressive.
9. Why does HVAC default to footwell outlets upon restart? Keep last state for everything!
Mine remembers the setting, but I never use full automatic. I use automatic for the temperature, but manual fan speed and direction.
