Not really. You'll find that he signed a contract stating they have a right to do this. This is standard contracteze for those who buy from those no credit lots. They put equipment (immobilizer with GPS) into the vehicle to do exactly this until the vehicle is paid off. If they miss a payment the vehicle is turned off. Take too long to catch up and they pick it up. But without the contractual clause they can't legally disable a vehicle until it has been lawful repossessed. Thus the contractual requirement.
