If version information conflicts before and after a rollback, freeze payment, shipment, or delivery for affected vehicles rather than relying on verbal explanations to continue. Arrange the VIN list, software baseline, update notes, recall status, and authorization records chronologically, and confirm which version is valid and who approved the change. If the discrepancy cannot be explained, make the decision again on the basis that updates cannot replace local recall obligations and customer-notification procedures, to avoid vehicle hardware being usable while recalls, OTA updates, or account services cannot be completed locally.
