I have had my NX200t Sport for several months. I love the car but have found a serious problem. I would be driving and suddenly the compression went off completely. No power at all. And there was a notice that I had my foot on the brake and the accelerator at the same time. Not true. I did not. I would frantically pump the accelerator to try to gain control of the car, and it would come back on. It happened at least 2-dozen times in 2-days. I called the dealership and they said to de-activate the automatic parking brake. I did. It did not resolve the problem at all. I drove the car the third day, and the problem lessened. And by the fifth day, it subsided completely. I have a hunch it was a computer glitch. Also, when I drive over 70-miles per hour I have a very loud wind noise in the car. The first time it happened I checked to see if the moon-roof was open, or perhaps a window had come open. No. Nothing. I have since heard that a friend's NX does the same thing and she took it to the dealer and they said it could not be fixed. Are either of these problems significant to anyone else? I'd like to know. Thanks a lot.
