“The problem started over five weeks ago. The car would not start once I put it in park. I've had the park neutral sensor switched changed and every time it happens which is after the forth or fifth time I put it in park. I've had the called towed over 10 times and my insurance has been canceled because of it. The dealership just keep tightening the gear shift but as I said when I drive it, it loosen up and the same thing happens. I think it doesn't start because the security systems kicks in when I try to put the car in gear.”
