Wheel collider bounce backward

Hey Unity community,

I am facing an issue with my car which uses wheel colliders. Sometimes I’ll be moving forward over the terrain(simple landscape made in blender with a mesh collider on it) and the car will randomly bounce backwards as if it hit a wall. It seems to happen randomly. The car is a rigidbody and has 4 wheel collider and it is moved by using WheelCollider.motorTorque. The collider on the car does not interfer with the wheel colliders. Anyone have a similar problem?

Thanks in advance,
Mike G.

Alright I think I figured it out. I was setting the velocity of the car to 20 if it ever got above 20, but since the wheels would still spin the sudden velocity reset would send the car backwards.
