G35 2007 won’t accelerate
 

I was in a minor fender binder. Since then it wont accelerate past 2k rpm.

Stuck in limp mode, get it OBD2 scanned and find out what's wrong, or take it to the dealership and let them fix it.

Sometimes a good visual check of the engine compartment is all that's needed, something may have popped loose, do all of your lights work? If you have ones that are no longer functional you may just have a wire pinched that's screwing up the whole electrical system. Pictures of the damage will help.
