When arriving at any destination and turning off the car, it is not possible to start the engine again immediately. When this failure first appeared, I needed to wait for about an hour in order to start it again, or else it wouldn't respond. Now, the failure is even worse, and more time needs to be waited until the car starts working again. It feels as if the car were blocked; I've taken it to the alarm service, mechanics, but no one has been able to solve my problem.
