You must have hit that curve pretty hard? But you have too many fault codes on here and maybe even more that you do not know about? For now do this and this may get you to be able to drive the car. Remove the battery out of the car disconnecting ground cable first and then the positive cable and touch both positive and ground cables together and let it sit that way for a couple of hours. This should reset all your control modules in the network. Do not close the trunk or you may not be able to open it up again? After a couple of hours separate the cables and install the battery back. Install positive cable first then the ground cable. Start it up and drive around. If you still have issues you will need to take it in to a shop for proper diagnosis.
