Any check engine lights came on? If so pull out your code reader, (buy one it's about $60-80) and see what's the problem.
That's if you haven't already towed it to a shop or not.
If the engine does sound like that in the video, then it's not looking good.

Also. Depends what mods you have on the car. With only 43k your in warranty. If one dealer gives you lip, take it to another.
