Do You Really Need To Follow Your Car’s Factory Maintenance Schedule?

May 20, 2025

The service light illuminates on your car’s dashboard—it’s time for routine maintenance.


If you’ve seen this notification pop up and wondered why your car says “maintenance required,” it’s because most car manufacturers have schedules for basic repairs and tune-ups. Regular maintenance like rotating tires, replacing spark plugs and filters, and changing brake fluid can keep your car running well and prevent bigger repairs down the road.


But you might be asking: Do I really need to do all the maintenance they recommend? Should I follow the schedule exactly?


The short answer is “yes.” Here are three surprising things you might not know about factory-scheduled maintenance.


1. A ton of research goes into the recommendations.

Most manufacturers have spent millions of dollars to figure out what items need to be serviced or inspected for each year, make, and model of their cars. Some items are due by mileage, some by time, and some by whatever comes first. 


These recommendations are developed by the engineers and techs who designed and built your vehicle (not by the sales team at the dealership), and they are customized to your car. In other words, they’re legitimate. 


2. They vary by make, year, and model—so make sure you know what your car requires.

Not every manufacturer is the same when it comes to when and what services are due at specific mileages. The manufacturer’s maintenance schedule not only varies by make but often by year and model as well. For instance, spark plugs are due every 40,000 miles on most Volkswagen and Audi models; some, however, on some, they’re due every 50,000 miles. On Mercedes, spark plugs are due every 60,000 miles or 5 years—whichever comes first.


3. It’s important to pay attention to them.

We promise: The manufacturer’s recommendations aren’t part of a secret marketing deal between car makers and repair shops. These really are essential repairs that will keep your car driving longer.



These routine tune-ups prevent damage to bigger, more expensive parts of your car. And if you have a specialty car like a BMW or Mercedes, these recommendations become even more important—high-performance vehicles require high-end care.


 If you want to get high mileage out of your car—and peak performance while you own it—it’s time to stop ignoring the manufacturer’s maintenance schedule and build a relationship with an auto repair shop that understands European and Asian vehicles.


At Import Specialty Service, we know the routine maintenance requirements of European and Asian imports like the backs of our hands. Our expert technicians will not only keep your car in top shape, but they will also advise you on what maintenance is necessary for your specific make and model.

Infiniti’s navigation system
May 19, 2025
Is your Infiniti’s navigation system your primary means of navigation, only to become unresponsive, provide incorrect directions, or not load maps at all? Infiniti has developed an infotainment system that is supposed to enhance the ease of driving, but it can be a lot to deal with when it develops some issues. A poor navigation system is quite irritating, especially if you are in an unfamiliar area or on a tight schedule. If you are having issues with your car’s navigation system, you are not alone. Many other users of Infiniti cars have also complained of the same issue. Some of the problems reported by many Infiniti owners include slow response, wrong information on the map, or even complete system breakdown. Here are the causes of these glitches and how to rectify them so that you can have a reliable system again. Why Does the Infiniti Navigation System Go Bad? Software Bugs and Outdated Maps: Infiniti’s car navigation system utilizes software that requires updates at some point to work as expected. If the system has not been updated for some time, it may contain errors or outdated information on the map, affecting the directions and roads. The system may also lock up or crash due to software errors. Interference of GPS Signal: A bad GPS signal can be a major issue affecting the navigation of your Infiniti. This can occur when driving through tunnels, big buildings such as in towns or cities, or areas with bad satellite signals. Sometimes, it can be due to a faulty GPS antenna that stops the system from getting the correct location information. Electrical Issues and Wiring Problems: The navigation system utilizes several electrical connections and circuits. If there is a problem with the power supply or faulty wiring, the system may not work as expected. Some issues include the screen fading, the system freezing, or the audio getting interrupted. Hard Drive or SD Card Failure: In some Infiniti models, the maps are stored on the car's navigation system's hard drive or SD card. If this storage device is damaged or corrupted, the system may take a long time to load the map or freeze. A faulty hard drive can also cause slow boot time and interrupted navigation capability. Touchscreen Issues: Other issues reported by Infiniti owners include unresponsive buttons or a frozen screen. These can make it difficult to enter the address displayed on the screen or even to change the settings. These problems can be caused by software issues or physical damage to the screen. How to Troubleshoot Infiniti Navigation System Problems Check GPS Signal Strength: If the system frequently loses signal, try going to a more open area to enable the GPS to lock on to satellites. Some problems may require a technician to check the GPS antenna for defects. Restart or Reset the System: If you experience a few minor issues while using your car's infotainment system, you can turn off the car and then on again to solve the problem. If the issues are not resolved, a system reboot may help fix them in the software. Check Touchscreen and Buttons: If controls do not respond, this may be due to software problems or button damage. A professional inspection is needed to determine whether certain parts need to be repaired or replaced. Ensure You Have the Latest Software and Maps: It is always recommended to have the latest software installed in your car to avoid any hitches. Companies like Infiniti release new software to patch up some glitches and enhance other features.
