Why does the maintenance reminder appear just after the car was serviced?

Just after the car was serviced, the maintenance reminder appears because the maintenance alert was not reset after the last service. Here are the relevant details: 1. Some cars allow manual oil life reset, while others require a computer to do so. If the repair shop doesn't have the necessary computer, the oil life cannot be reset, leading to repeated maintenance reminders. Even at 4S shops, this can happen if the technician forgets to reset the oil life. 2. Maintenance reminders vary in style—some cars display a wrench icon, while others use text directly. The methods for calculating oil life also differ. Some cars allow setting a specific mileage, such as 5,000 km for the next service, while others don't support mileage settings and simply require pressing the oil reset button to restore the oil life to 100%. 3. The original purpose of the maintenance light is to remind the owner to service the car promptly. Therefore, the owner should visit a 4S shop as soon as possible. After servicing, the 4S shop will use a diagnostic tool to reset the maintenance light. The quickest and most accurate way to clear the maintenance reminder is by using a diagnostic tool.

I recently encountered this issue too - the maintenance reminder popped up right after servicing, which really confused me. Actually, this is quite a common problem, mostly caused by technicians forgetting to reset the reminder system after maintenance. The vehicle's computer triggers alerts based on preset mileage or time intervals for services like oil changes or tire inspections. If the system isn't manually reset during maintenance, the reminders keep appearing. I recall there's a simple solution: check your owner's manual to find how to access the dashboard settings menu. Many vehicles just require holding down a dashboard button or turning a knob to reset the reminder. If you're not familiar with it, it's better to drive back to the service center and let them handle it to avoid hassle. Of course, this reminds me to proactively ask technicians about this during future maintenance appointments. Ultimately it's not a serious issue, but should be addressed promptly to prevent misjudging the vehicle's condition.

As a guy who often tinkers with cars, I've encountered this issue quite a few times. The maintenance reminder stays on because the vehicle's diagnostic system wasn't reset. That thing relies on sensors and computer algorithms to monitor service intervals, and requires manual or tool-activated reset after maintenance. For example, pressing specific button sequences before turning the key to the second position, or connecting an OBD tool. Many buddies overlook this, ending up with that annoying reminder staying lit. I suggest confirming the reset is done with the technician during next service, and ask if you can learn the procedure yourself. Also make regular checks to ensure the system works properly. This prevents false alarms affecting vehicle performance - proper maintenance keeps your ride smooth.

I've been driving for several years, and this is quite simple. The alert popped up right after the maintenance, probably because the technician didn't reset the system. The vehicle's computer is set to remind you of maintenance, and it needs to be manually reset after service, otherwise it will keep alerting as usual. Check the manual to find a button to press. If that doesn't work, take it back to the shop and have them do it. Don't worry, there's nothing wrong with the car itself.
