How many kilometers can the first maintenance exceed?

[Monica]

The first maintenance can exceed 500 kilometers. The first maintenance time for a car is between 3 to 5 months, with a mileage range of 3,000 to 5,000 kilometers, and even up to 8,000 kilometers for some models. This variation is due to differences in specific technical conditions of vehicles. Generally, the first maintenance should not exceed 5,000 kilometers. Below is additional information: 1. First maintenance mileage: Typically, the first maintenance is performed around 5,000 kilometers, though many 4S shops now recommend maintenance at approximately 3,000 kilometers. 2. Maintenance precautions: Maintenance generally involves checking the vehicle for issues, changing the oil and filters, and sometimes includes services like applying protective films. During maintenance, pay attention to the oil change process, as many 4S shops may claim to use fully synthetic oil during maintenance when selling the vehicle.

I've been repairing cars for over a decade, and the first maintenance is something you really need to take seriously. When a new car first rolls off the production line, there are some metal shavings inside the engine, and the first maintenance is meant to clean them out. The manufacturer-recommended first maintenance mileage, like 3,000 kilometers or 5,000 kilometers, is based on scientific reasoning. If you exceed it by less than 200 kilometers, the 4S shop can usually accommodate you, but going over 500 kilometers is a big problem—the oil filter will already be clogged with metal powder, essentially causing the engine to grind dry. I've had clients who came in for maintenance after exceeding the limit by 800 kilometers, and when we opened up the engine, the cylinder walls were full of scratches. What's even more troublesome is the warranty issue—if you exceed the limit by more than 500 kilometers, the manufacturer has grounds to deny coverage. My advice is not to push your new car too hard; it's safest to schedule maintenance early.

As a professional who deals with maintenance records on a daily basis, I can clearly tell you that policies vary by brand. German cars are generally strict, with exceeding 300 kilometers considered a breach; domestic brands may allow up to 500 kilometers. Exceeding the first maintenance limit directly affects three aspects: first, excessive metal shavings can scratch the crankshaft; second, residual acidic substances corrode sealing rings; third, it impacts the warranty chain for the subsequent nine maintenance services. I've handled cases where a customer's transmission failed after exceeding 800 kilometers, and the manufacturer denied the claim after retrieving the data. It's advisable to sign a supplementary agreement when purchasing at a 4S dealership to secure a 200-400 kilometer buffer. An emergency method is to use your phone to track the countdown mileage for the first maintenance and check it daily.
