When complaint closeout follow-up is checked remotely, the static documents and the on-site footage have to point to the same unit. Before release, see whether the solution, the customer confirmation, and the later observation support one another, since no single requirement alone settles the question. Where a ticket is closed in the system while the problem is not confirmed gone and that blocks release, stop work on the affected vehicles, then trace which handover produced the difference. Cross-checking against this dealer purchasing verification guide reduces omissions between steps. Responsibility negotiation and vehicle repair for complaint closeout follow-up can run in parallel, with closure only when both are done.
