weird problem

hi
im facing some weird problem in my w164 ML350 2011
some times when i try to turn on the engine it wont start but when i disconnect the battery for about 10 seconds and reconnect it, it works fine the while im driving in a normal way surprisingly all the dashboard lights gets on and the fuel & RPM indicator gets off and the speed indicator keeps jumping from 0 to about 40 all the way and the gearbox starts knocking hardly and when you stops the car and turned it off it will not start the engine until you disconnect the battery for about 10 seconds then it will starts again normally.
and when i go to the workshop the man said it could be from the ignition switch,, have any one faced the same problem?

When’s the last time you thoroughly cleaned the battery terminals and grounds? What is the battery voltage with the car off and when running? Most modern cars go haywire if those items are not in good shape.
