I hit a carve and replaced everything now it doesnt drive over 30 miles.

What is your question?

I have a wv jetta 2016, a month ago my nephew wanted to drift it and he failed to drift, hit the rear driver side in a curve the driver seat and shoulder airbags blew up. now the car doesnt drive over 30mph. even i replaced everything. is there a fuse that control the speed that stuck by 30mph or there is something that needs to be replaced to let the car drive over 30miles? I appreciate an Idea.
