Maintenance & Diagnostics

Maintenance Schedule

What an electric car needs and when: tyres, brakes, filters, coolant, 12 V battery and software.

Safety first: this content is educational. Never work on energized high-voltage parts (orange cables) unless you are HV-qualified.
Tyre pressure & tread check

EVs are heavy and torquey — tyres wear 10–20% faster. Check cold pressures against the door-jamb placard.

Monthly
Owner check
Tyre rotation

Evens wear front-to-rear; essential on dual-motor cars.

Every 10,000–13,000 km
Enthusiast
Wiper blades & washer fluid

Same as any car.

Every 6–12 months
Owner check
Cabin air filter

Affects HVAC efficiency and heat-pump airflow.

Every 1–2 years
Owner check
Brake fluid test/replace

Fluid absorbs moisture regardless of how little the pads are used.

Every 2 years
Professional
Brake caliper clean & lubricate

Regen means calipers rarely work hard and can seize from corrosion.

Yearly (salted roads)
Professional
12 V battery test

A weak 12 V battery is the #1 cause of EVs that won't 'wake up'.

Yearly after year 3
Enthusiast
Coolant (battery/drive unit) check

Dedicated low-conductivity coolant. Never top up with generic antifreeze.

Per manufacturer, ~4–8 years
Professional
A/C desiccant & refrigerant service

Heat-pump systems depend on correct refrigerant charge.

Every 4–6 years
Professional
Suspension, steering & bushings inspection

Extra vehicle mass loads bushings and ball joints.

Yearly
Professional
Software updates

Install updates — they often improve charging, efficiency and fix faults.

As released
Owner check
HV battery health report

State-of-health readout via dealer or diagnostic tool. No routine HV service needed.

Yearly / before sale
Professional

Intervals are typical; always follow your manufacturer's service schedule.
