My Hero Maestro stopped 2 times on the road (on its own), what could be the problem?
You can ask them to clear the issue or change the required part as there is nothing as such in the scooter which cannot be replaced or repaired. You should leave the scooter at the service station and ask them to deliver the same when they are sure that the fault won't occur again. You can even contact 1800 266 0018 for registration of your complaint if you think the dealer is not dealing with the thing properly.
