Electric vehicles (EVs) are often promoted as being cheaper and easier to maintain than petrol cars – and in many ways, that’s true.

Because EVs have far fewer moving parts than traditional internal combustion engines, they avoid many of the common servicing costs associated with petrol and diesel vehicles.

But that doesn’t mean EVs are maintenance-free.

Here’s what EVs do – and don’t need when it comes to servicing.

Why EVs Need Less Maintenance

A traditional petrol engine contains hundreds of moving components working together under heat and pressure.

An EV drivetrain is much simpler.

There’s:

  • No engine oil
  • No spark plugs
  • No exhaust system
  • No timing belt
  • No fuel injectors

With fewer moving parts, there’s simply less to wear out or replace.

That’s one of the biggest reasons EVs often cost less to maintain over time.

What EVs Don’t Need

🛢️ Oil Changes

EVs don’t use engine oil because there’s no internal combustion engine.

That means:

  • No oil changes
  • No oil filters
  • No engine lubrication servicing

This alone can significantly reduce routine servicing costs.

🔧 Spark Plugs & Engine Tune-Ups

Petrol engines rely on spark plugs to ignite fuel.

EVs don’t burn fuel at all, so there are:

  • No spark plugs
  • No ignition systems
  • No engine tune-ups required

💨 Exhaust Repairs

Because EVs produce no exhaust emissions, they don’t need:

  • Exhaust systems
  • Mufflers
  • Catalytic converters

That removes another major maintenance item common in petrol vehicles.

What EVs Still Need

Even though EVs require less maintenance, regular servicing is still important.

🛞 Tyres

EVs are often heavier than petrol vehicles because of their battery packs.

That extra weight, combined with instant torque – can increase tyre wear.

Regular tyre checks help with:

  • Safety
  • Efficiency
  • Handling
  • Maximising driving range

Tyre pressure is especially important in EVs because underinflated tyres can reduce efficiency and range.

🛑 Brakes

Many EVs use regenerative braking, which helps slow the vehicle while recovering energy back into the battery.

This reduces wear on brake pads compared to petrol cars.

However, EVs still need:

  • Brake inspections
  • Brake fluid checks
  • Brake servicing over time

Because regenerative braking is used frequently, traditional brakes may actually get used less – which can sometimes lead to surface rust if left unchecked.

❄️ Battery Cooling Systems

EV batteries operate best within specific temperature ranges.

Many EVs use liquid cooling systems to help regulate battery temperature.

These systems may require:

  • Coolant inspections
  • Coolant replacement
  • System checks

Battery temperature management is important for:

  • Battery lifespan
  • Charging performance
  • Vehicle efficiency

🔋 Battery Health Monitoring

The battery is one of the most important parts of an EV.

Servicing may include:

  • Battery health checks
  • Software diagnostics
  • Charging system inspections

Many EVs also receive software updates that improve:

  • Efficiency
  • Charging performance
  • Vehicle systems

Some updates can even be completed remotely.

🚗 Suspension & Steering

Like any vehicle, EVs still experience wear on:

  • Suspension components
  • Steering systems
  • Bushings
  • Shock absorbers

New Zealand roads can be tough on suspension over time, regardless of the type of vehicle.

Do EVs Cost Less to Service?

In general – yes.

Because EVs avoid many traditional engine servicing items, maintenance costs are often lower over the life of the vehicle.

Savings commonly come from:

  • No oil servicing
  • Fewer moving parts
  • Reduced brake wear
  • Less drivetrain maintenance

However, tyres and suspension can still be significant long-term costs depending on driving habits and vehicle weight.

How Often Should an EV Be Serviced?

Servicing intervals vary depending on the manufacturer and model.

Many EVs still require:

  • Annual inspections
  • Regular safety checks
  • Scheduled servicing

Always follow the manufacturer’s servicing recommendations.

Bottom Line

EVs generally require less maintenance than petrol vehicles – but they still need regular servicing and inspections.

While you can forget about oil changes and spark plugs, tyres, brakes, battery systems, and suspension components still need attention over time.

👉🏼 Lower maintenance is one of the biggest advantages of EV ownership – but regular servicing still helps keep your EV safe, efficient, and performing at its best.
