Today I had a brake light and battery light come on at once and they don't go away. Then after they came on I now have a car that turns off for a fraction of a second, all the lights come off, the car jerks and then it goes back on. Please help!

 

so wait after shutting your car off it comes back on??

and please dont double post :^/

 

sounds like a loose negative battery cable, my z did the same thing once, and all i did was tighten the negative cable.
