I have made a car. I have seperate collision groups for the body and the wheels so that they dont collide with each other. the car is working perfectly fine but when i get into the car it jerks and the wheels and springs go to random places and get kinda stuck and the car bounces and jerks. even when i collide with a wall or a slightly big block it does the same and then becomes normal after few seconds. it is working smoothly on plane and inclined surfaces. I have shown it in video below.
