How Vehicle Age Affects Maintenance and What You Need to Know

...

When it comes to maintaining your vehicle, its age plays a crucial role in how frequently it needs servicing and the types of repairs it may require. In New Zealand, vehicles are getting older, and this trend is something every driver should consider when looking at their car maintenance schedule. According to the New Zealand Transport Agency (NZTA), understanding vehicle age trends can help you predict future maintenance needs and ensure the longevity of your vehicle.

Vehicle Age Distribution in New Zealand: A Growing Trend

As of the latest NZTA data for 2024, here’s a look at the age distribution of vehicles on New Zealand’s roads:

  1. Vehicles Aged 0-5 Years:
    • Percentage: 29.8% of the fleet
    • This category consists primarily of new vehicles or those in their early years of operation. These vehicles typically require less maintenance than older cars, although regular oil changes, tire rotations, and brake inspections are still essential.
  2. Vehicles Aged 6-10 Years:
    • Percentage: 27.6% of the fleet
    • As vehicles age, the frequency of maintenance increases. The 6-10 year range is critical for preventative care, especially for issues such as engine performance, suspension, and wear on vital systems like the cooling and braking systems.
  3. Vehicles Aged 11-15 Years:
    • Percentage: 18.2% of the fleet
    • As the vehicle enters the 11-15 year range, it may start showing signs of wear and tear. Common issues for vehicles of this age group include exhaust system deterioration, battery life reduction, and suspension wear. Regular inspections are key to preventing breakdowns.
  4. Vehicles Aged 16-20 Years:
    • Percentage: 11.4% of the fleet
    • Vehicles in this age group often require more significant repairs. At this point, many components of the vehicle; such as the transmission, power steering, and air conditioning system, may start to fail or show signs of serious wear. These cars often need specialized services to keep them roadworthy.
  5. Vehicles Aged 21+ Years:
    • Percentage: 13% of the fleet
    • Vehicles over 21 years old account for 13% of New Zealand’s fleet, and these cars often require extensive maintenance. While some older vehicles are maintained in excellent condition, the likelihood of costly repairs increases significantly in this category.

The Importance of Regular Maintenance Based on Vehicle Age

As the data shows, a significant portion of New Zealand’s vehicle fleet consists of cars that are 6 years or older. With these vehicles, the risk of breakdowns and mechanical failures increases, especially if they’re not well-maintained. For vehicle owners, this means paying attention to the following:

  • Regular Oil Changes and Fluid Checks: As your vehicle ages, keeping track of oil changes becomes even more critical. Older engines tend to accumulate more dirt and debris, which can affect performance. Regular oil changes can help extend the life of the engine.
  • Brake and Suspension Systems: For vehicles in the 6-10 year range and older, ensuring that brakes and suspension systems are in top condition is essential for safety. Worn-out brakes and a compromised suspension system can lead to costly repairs and increased risk of accidents.
  • Battery and Electrical Systems: Older vehicles often experience battery degradation. A professional technician will check the battery and electrical systems to ensure they’re functioning properly and avoid sudden power loss.
  • Timing Belts and Chains: For vehicles in the 10-20 year range, checking the timing belt or chain is vital to avoid catastrophic engine failure. Replacing these parts before they fail can save you from expensive repairs down the road.

Why This Matters for You

Whether you drive a brand-new car or one that’s over 20 years old, the data from the NZTA is a clear reminder of the importance of proactive vehicle maintenance. If you drive one of the 29.8% of vehicles under 5 years old, you may be able to extend your service intervals, but that doesn’t mean you can ignore regular check-ups. For older vehicles, staying on top of regular maintenance and addressing issues before they turn into major problems can save you money and extend the life of your car.
