Yes. When it did the no-power thing, it ignored my attempt to shift into manual mode. The display said "D", but it would not go. I even tried going to "P", which it obliged, then back to "D". It still would not switch to manual. There is another post where the details indicate that the transmission seemed to stay in an inappropriately high gear after a stop. That would make sense based on my years of driving vehicles with manual transmissions. If you try to pull out from a stop, in 3rd or 4th gear, you can do it, but it requires really high rpms, and a ton of fine clutch work/slippage.
I cannot recreate the no-power issue. The transmission temp warning may be easily recreated by performing about 6 or 8 sporty starts and dead stops. This is something you might do if going through a series of stop signs, for example. The vehicle will suggest that you "pull over safely". Excuse me?
Also, cold weather does seem to make this vehicle act up much more often. I thought they had cold winters in Korea. My backup camera and radio fail intermittently when the ambient temperature is below 20. Also, the clutch slippage behavior in low gears is more pronounced in those conditions.
