15 Tucson changed the dual clutch and won't go.

It may be that the throttle is too dirty, or it may be a problem with the gearbox.

You can go to the 4s shop and have a computer diagnosis. You have encountered a similar situation before. Walking alone is not enough, but the reaction to stepping on the accelerator is very slow, and it is impossible to lift it at a slow speed. The next day, when I was ready to go to 4S, I found it inexplicably better, but I went to check it. According to the fault code, it is estimated that there is a bad connection in the line, and I didn't deal with it. Let me open it for a while. It's almost two years now, and I haven't met it again.
