Parent Rigidbody with child Kinematic rigidbody acting weird

I have a car with wheel colliders and I want to open the doors and hood which are child of my main car on mouse down. My parent car has a Rigidbody and the child that I want to interact with has Rigidbody with Kinematic enabled. Without any outside force my car is acting weird and is constantly dancing around the ground.

Please Help!!!

Use this to make the door not collide with the car:
