my CL63 refuses to start first time. I have to take the key out and lock it and unlock it several times until it eventulally cranks and then it starts and runs no problem. Also sometimes the car gets stuck in a gear, it could be any gear, and it happens particularly if I accellerate quickly. If I stop the car, turn it off and start it again it is ok! do you think these two issues are related? is this a common problem with a simple fix or should I brace myself for a big bill? Thanks for all your help.
