Electric vehicles (EVs) are often marketed as low maintenance, but what does that actually mean for UK drivers?
It’s true that fully electric cars have fewer moving parts than petrol or diesel vehicles. However, having fewer components does not mean servicing isn’t necessary. Like any vehicle, EVs still require regular inspections, safety checks and preventative maintenance to remain reliable and roadworthy.
Here’s what you need to know.
Do Electric Cars Need Less Maintenance?
In short: yes, but not zero maintenance.
Fully electric vehicles do not have:
- Engine oil
- Oil filters
- Spark plugs
- Fuel filters
- Timing belts
- Exhaust systems
Because there’s no internal combustion engine, EVs don’t require traditional oil changes. That immediately reduces routine servicing costs.
Hybrid vehicles, however, still have an engine and may still require oil changes, although sometimes less frequently depending on usage.
What Maintenance Do EVs Still Need?
Despite fewer moving parts, EVs still require regular professional checks.
1. Battery State of Health (SOH) Checks
The high-voltage battery is the most expensive component in an EV. Over time, all lithium-ion batteries degrade.
A battery state of health check assesses:
- Remaining usable capacity
- Charging performance
- Thermal management system operation
- Fault codes within the battery management system
Monitoring battery health helps identify early signs of degradation and protects resale value.
2. Brake System Maintenance
EVs use regenerative braking, which slows the vehicle by using the electric motor to recover energy. This reduces reliance on traditional friction brakes, especially rear brakes.
While this sounds positive (and it does reduce brake pad wear), it can create an unexpected issue: rear brake components can seize due to lack of regular use.
In the UK, with wet weather and road salt during winter, brake corrosion is common. If rear brakes aren’t used frequently enough, callipers and discs can corrode and stick.
Regular inspections and brake servicing are essential to prevent costly repairs.
3. Suspension & Steering Components
EVs are often heavier than petrol vehicles due to battery packs. The additional weight can place more strain on:
- Suspension arms
- Bushes
- Shock absorbers
- Tyres
UK road conditions, including potholes and uneven surfaces, accelerate wear.
4. Tyres
EVs typically produce instant torque, which can increase tyre wear compared to conventional cars.
Correct tyre pressures and regular checks are crucial for:
- Safety
- Efficiency
- Maximising driving range
5. Cooling Systems
Electric vehicles use liquid cooling systems to regulate battery temperature. Coolant levels and system integrity must be maintained to protect battery longevity.
6. Cabin Filters & Air Conditioning
EVs still require:
- Cabin pollen filter replacement
- Air conditioning servicing
- System disinfecting
These are essential for comfort and air quality.
Do EVs Still Need Annual Servicing?
Yes. Most manufacturers recommend annual servicing or servicing at specific mileage intervals. This ensures:
- Warranty compliance
- Software updates
- Safety inspections
- Battery system monitoring
Skipping servicing may invalidate warranty coverage.
Are EV Repairs More Expensive?
Routine maintenance costs can be lower than petrol or diesel vehicles. However, specialist training and equipment are required to safely work on high-voltage systems.
That’s why choosing a qualified garage is critical.
What About Hybrids?
Hybrid vehicles combine electric motors with petrol engines. They still require:
- Oil changes
- Engine servicing
- Hybrid battery checks
- Brake inspections
Maintenance needs depend on how often the engine is used.
The Importance of Specialist EV Expertise
Electric vehicles require technicians trained in:
- High-voltage safety systems
- EV diagnostics
- Battery management systems
- Software calibration
At Auto Service & Tuning Centre, we understand the technical requirements of electric and hybrid vehicles. From battery health checks to brake maintenance and advanced diagnostics, we ensure your EV remains safe, efficient and warranty compliant.
Final Verdict: Do EVs Really Need Less Maintenance?
Yes, but they still need proper servicing. Electric vehicles don’t require oil changes and forgo many engine-related repairs. However, they still require:
- Battery health monitoring
- Brake system maintenance
- Suspension checks
- Cooling system inspections
- Tyre monitoring
- Software updates
Ignoring these can lead to unexpected and expensive issues.
