9 Most Often Replaced Car Parts

fixing tyres

No matter how careful a driver you are, your vehicle will naturally get damaged by normal wear and tear. In addition, depending on various factors such as how often and where you drive, some parts will wear out faster than normal. Here’s a quick list of car parts that get replaced more frequently than others. This can help you monitor their status and get new parts on time.


Car tyres don’t last forever. Not even those huge, heavy-duty ones that you put on off-road trucks. If you drive often and over long distances, the treads will wear down much faster. There are also road hazards that can puncture or cut the tyres, not to mention issues like incorrect alignment that can result in uneven wear. However, as long as you rotate your tyres and drive at reasonable speeds, you’re likely to get 90,000 kilometres or more out of a quality set of tyres.

Rotors and Brake Pads

Rotors help keep your vehicle’s brake system from overheating. If you’re an aggressive driver or often get caught in stop-and-go traffic, the rotors can get worn down faster than usual and increase the risk of brake failure. Some indications that the rotors are ready for replacement include squeaking or grinding sounds when you brake, as well as a pulsing brake pedal.

Squeaks and squeals when braking may also indicate worn-down brake pads. Do note that large trucks require more power for braking, so the brake pads may need replacement more often. Try to find brake pads that generate less dust, since this type can last longer than standard ones.

Bumpers and Grilles

Road and outdoor debris like small rocks and branches can cause a lot of damage to your car. The occasional grazes and near-misses with other vehicles can also result in bumps, scratches, and dings. Even a stray trundler in a supermarket’s parking lot can nick the paint or cause a dent. This is why bumpers, grilles, and other exterior parts get replaced a lot. Make sure to go to a reliable auto parts supplier in NZ to get quality components that ensure not just your car’s good looks but also its safety.

Rear Exterior Lights

Your car’s exterior lights like the turn signals, brake lights, and tail lights get burnt out faster than headlights or fog lights. Perform regular maintenance checks to ensure that these lights are working properly. You can replace the bulbs yourself; just refer to the owner’s manual and you’ll find instructions on how to remove and replace the housing and bulbs. As with any other car part, make sure to get the light bulbs from reliable suppliers to ensure quality. 


There are a lot of factors that can cause battery failure. These include the battery’s age itself, bad driving habits, and taking few and short trips that don’t charge the battery properly. Most car batteries need replacement every four to five years. It’s a good habit to check for damaged cables and dirty terminals every so often since these can cause the battery to fail even if the battery itself is still in good condition.


The alternator is what charges your car’s battery and supplies the power to run the electrical systems. If your vehicle is often used in demanding situations, the alternator’s lifespan can decrease significantly. However, alternators also often get misdiagnosed. Sometimes, poor electrical connections are the culprit. Therefore, make sure to get the alternator tested first before you get it replaced. 

Spark Plugs and Fuses

Are you having trouble starting up your car? Is it slow to accelerate? Does the engine surge? You might need to replace the spark plugs to fix these issues. Meanwhile, problems with instruments such as windshield wipers or the air-conditioning can be caused by blown fuses.

Fortunately, these are relatively inexpensive replacement and the process is also not too complicated. Refer to the owner’s manual to locate the spark plugs and fuses. Check for signs of damage and replace the parts when necessary.


Your vehicle’s clutch can last for 200,000 kilometres or more. However, aggressive driving styles, bad driving habits like “riding the clutch,” and towing can all shorten the clutch’s lifespan. Larger vehicles like trucks and utes may also need more frequent clutch maintenance and replacement, especially when used on rugged terrain.

Make it a habit to inspect your car regularly.  Remember: a well-maintained car is a safe car.
