Can maintenance be performed outside of 4S stores during the warranty period?

[LeRuth]

Maintenance can be performed outside of 4S stores during the warranty period, but if the car owner chooses to have maintenance done at an external repair shop without authorization during the warranty period, the manufacturer may refuse to provide compensation if problems arise. Therefore, it is advisable to opt for maintenance at 4S stores while the vehicle is still under warranty. The automobile three-guarantee policy stipulates that during the warranty period, consumers must have maintenance performed at 4S stores authorized by the manufacturer to enjoy the three-guarantee benefits. If maintenance has been performed outside of 4S stores, to avail of the three-guarantee services, a series of relevant documents must be provided, including the repair shop's qualifications, material lists, maintenance items, quality inspection reports, duplicate copies of the completion and factory qualification certificates, and proof of purchase. Car maintenance refers to the preventive work of regularly inspecting, cleaning, supplying, lubricating, adjusting, or replacing certain parts of the vehicle, also known as automobile upkeep.
