I have solved the problem.
The problem was related to some inertias being too small, probably causing numerical issues or crashes. In this case the wheel inertia ended up being less than 0.0001 (due to a low wheel weight) which seems to have caused the problem with the car being stuck in the ground when controllers and transmission were attached to the wheels.
Furthermore I realized that the same thing can happen if the PID constants for the controllers are too small.
