Car maintenance is essential not just for your car but also to keep enjoying the benefits of your extended warranty. While most people prefer taking their cars to the nearest workshop for routine maintenance, some prefer the DIY route. However, does service your own car risk voiding your warranty? In this article, we look at the dos and don’ts of servicing your car. We look at the cost and correct methods of servicing a vehicle that’s under warranty.

Car Servicing Overview

If your car has a warranty of any kind, it will require you to subject your vehicle to regular maintenance. Failure to do so could void your warranty. However regular maintenance does not necessarily mean taking your car to an authorized workshop. Most warranty providers will specify the guidelines that need to be followed for routine maintenance. Here’s a list of things covered under regular maintenance.

Check out our in-depth guide to learn whether or not an extended car warranty covers service costs and what it will and won’t cover.

Service Changes

Routine maintenance covers several components that need to be replaced at different timelines to ensure optimal functioning of your vehicle which include:

  • Oil Change
  • Fluid Replacement
  • Tire Rotation
  • Oil Changes

According to AAA, motor oil should be changed between intervals of 3,000 and 7,500 miles depending on the type of engine you have but even if your car does not cover that mileage, it is still recommended to change your oil every 6-8 months. Oil changes are probably the most important aspect of car servicing as bad oil can lead to engine seizure. Other fluids that need to be checked, flushed, and changed every so often include:

  • Coolant (radiator)
  • Transmission
  • Brakes
  • Power steering
  • Windshield wiper fluid

According to experts, coolant and brake fluids need to be changed at least every 2 years and transmission fluid should be changed every 50,000 miles.


Tire wear is also subjective. While some tires might last longer than others depending on tire type and use, Edmunds recommends tire change at least every 6 years. U.S. News suggests getting your tires rotated every 7,500 miles or 6 months to even out wear and tear and to make them last much longer which puts them on the same schedule as oil changes.

Service Replacements

Other common parts that are subject to wear and tear and need to be replaced at regular intervals include:

  • Brake pads
  • Windshield wiper blades
  • Car light bulbs
  • Fuses

Depending on your vehicle and bulb type, your headlight system can last for years at a time. Brake pads and rotors on the other hand should last around 20,000 to 50,000 miles depending on use. Automakers such as Ford and Toyota recommend replacing rotors every 30,000 to 70,000 miles.

Wiper blades often need to be replaced every 6 to 12 months or as soon as you notice any squeaking noises, streaking on the windshield, or cracked and damaged blades, according to AutoZone.

Modern vehicles equipped with LED bulbs last much longer than regular halogens so if you have halogen bulbs, it is recommended to check them at least once a year but in the case of LEDs that interval can be as long as five years. Fuses will last an average of 10 years, according to YourMechanic, and besides aging, will usually only wear out due to electrical problems or component failure.

Can You Service Your Car And Keep The Warranty?

The short answer is yes. Under the Magnuson Moss Warranty Act, it is against federal law for car dealers and warranty providers to deny a claim or void a warranty if a vehicle has been subjected to proper maintenance by the owner. The only case where a warranty claim can be denied in the case of DIY servicing is if the job was performed incorrectly such that it causes damage or malfunction to the vehicle.

This is why it is always recommended to consult a technician or check the manufacturer’s online guide if you are unsure of what oil, fluids, or lubricants to use. Timely maintenance is also essential to ensure that your vehicle’s warranty isn’t void. If you neglect routine maintenance or fail to perform services such as oil changes or fuse replacement, your warranty claim may be denied and your warranty could be voided for pricier parts such as your car’s powertrain.

Servicing might sound like a complicated endeavor but it isn’t. So here’s a list of instructions to help you get started on servicing your vehicle:

  • Follow the car’s maintenance schedule: You can usually find it in the owner’s manual. Always know when tasks such as changing the engine oil, checking fluids and belts, and performing tune-ups need to be done.
  • Learn what to check during oil changes: Certain components need to be serviced or inspected between regularly scheduled oil changes, so look at the air filter, exhaust system, brakes, fluids, radiator, and battery.
  • Get the right tools and parts: Basic tools and materials include car jacks, oil and air filters, wrenches, screwdrivers, and pressure gauges. Thoroughly do your research to ensure repairs are done with the correct equipment.
  • Keep a paper trail: Maintain records for each service as proof to keep the warranty valid for future claims. You’ll need to record the date, mileage at the time of service, type of service performed, and receipts for parts and fluid purchases.
