If you don't upload it, you will be fined if it is checked by the manufacturer. You can ask 4S to upload. If the 4s shop does not deliver it to the manufacturer in time, it will affect the shelf life of your spare parts. For example, there is something wrong with your engine. The manufacturer will check the maintenance records. If it is not repaired on time, the manufacturer will use this as an excuse not to claim compensation. So every time you go to maintenance, you should keep the maintenance documents. If the manufacturer checks the maintenance records, it is the reason of the 4S shop, not its own.
