The first method: through the brand official website query. Every automobile brand has a corresponding official website, and you can find the information of maintenance records in the "after-sales service" or "customer service" section.
The second method: query through the mobile APP. For example, the WeChat applet searches for "checking the car". After input, you can enter the VIN code (frame number) for query. A detailed report will be provided after the inquiry, which is fast and full of information. You can also easily check the maintenance records of your car on it.
The third method: go to the 4S store for consultation. If you can't find your own maintenance records in the above two ways, you can directly consult the 4S shop authorized by the automobile brand, and they will help you find relevant information.
The above three methods are relatively simple and convenient, but it should be noted that the relevant information of the vehicle, such as frame number and engine number, needs to be prepared before the inquiry.
