Electric Car Servicing: What's Different?

EVs need less maintenance than petrol or diesel cars — but they still need it. Here's what to expect.

Electric vehicles are often marketed as 'low maintenance' — and compared to petrol or diesel cars, that's largely true. But they're not maintenance-free. Understanding what an EV needs — and what it doesn't — helps you budget correctly and keep your car in good condition.

What EVs Don't Need

Engine oil changes
Timing belt replacement
Spark plug replacement
Exhaust repairs
Clutch replacement (automatic only)
Fuel filter replacement
Catalytic converter servicing

What EVs Still Need

Tyre rotation and replacement — EVs are heavier than equivalent petrol cars, wearing tyres faster
Brake fluid change every 2 years — even though regenerative braking reduces brake wear, the hydraulic system still ages
Cabin air filter replacement — every 1–2 years
12V auxiliary battery replacement — usually every 4–6 years (separate from the main traction battery)
Coolant system service — EVs use liquid cooling for the battery pack and power electronics
Wiper blade replacement
Annual safety and vehicle check

Brake Wear on EVs

One of the genuine advantages of EVs is reduced brake wear. Regenerative braking — which recovers energy while slowing the car — does the majority of the deceleration work. Friction brakes are used much less, and pads can last twice as long as on a petrol car. However, this low usage can lead to brake disc corrosion from inactivity — a paradox where the discs rust faster because the brakes are used less. Regular checks ensure discs haven't surface-corroded to the point of affecting performance.

PKA Automotive services EVs for all maintenance tasks not related to the traction battery or high-voltage systems. We carry out tyre fitting, wheel alignment, brake fluid changes, cabin filters, and full safety checks on all electric vehicles.
