I was driving on grass when I went over a hole and was too big and my car went over to harshly. When I went over the hole I immediately put my car in park, harshly enough that the car stopped moving because of me putting it in park and not from me braking. Then I went outside to check for damage, I didn't see any damage. Then, I had my car idle when I started to hear a rhythmic noise coming from the center of the car. The noise can only be heard from the inside of the car. Then after a while of me hearing the noise, it became louder more high-pitched and the car even began to vibrate a little. Then the car turned off and the battery icon lit up on the dashboard. When turning it on right after the car struggled more than normal but when I turned it on after it was turned off normally it was fine. After I received the engine from low rpm to high rpm and drove the car around to no avail. The car still felt the same driving from before the incident and the revving did nothing.

Hello, you should have the underneath of the car checked by someone for damage to the wiring harness, especially around the oxygen sensors, the wiring for them is exposed under the car. Obviously something got damaged when you hit the ground. Putting the car up on a lift so someone can take a real good look.
