Hybrid and electric vehicles

Less routine maintenance does not mean no maintenance

EVs remove engine oil and many wear items, but tyres, brakes, suspension, cabin filters, cooling circuits and the 12V system still need attention. Hybrids add both combustion and high-voltage systems.

We route high-voltage inspection and repair only to appropriately equipped technicians and settings. Drivers should never open orange-cable, battery or inverter components.

Hybrid and electric vehicle safety and service check
High-voltage systems require trained people and controlled procedures.
Choose by symptom

Choose the EV or hybrid concern

These signs narrow down the sensible first step. They are not a diagnosis: two faults can feel very similar from the driver’s seat.

Routine EV service is due

Brakes, tyres, fluids, filters, charging equipment and diagnostic health still need scheduled checks.

Book an EV service

Range or hybrid behaviour has changed

A battery-health report can compare module condition and stored system data without guessing pack replacement.

Book battery health report

Vehicle is completely dead

The 12V battery wakes the control systems and can strand an EV even when the traction battery is charged.

Free checks before you book

Safe owner checks only

Only make checks that your vehicle handbook permits, with the car safely parked, switched off and cool where relevant.

  1. Inspect the charging cable and plug externally for obvious cuts, heat damage or contamination before use.
  2. Check tyres and conventional fluid levels using the handbook.
  3. Record warning messages and charging behaviour; do not remove covers or touch orange high-voltage cables.

Hybrid Car Service

A full service tailored to a hybrid, covering the petrol engine as normal plus the checks a hybrid needs: inverter coolant condition, high-voltage battery health and cooling, and the 12V battery. Hybrids still need oil and filters, they just need more besides.

Electric Vehicle Service

A service designed for a car with no engine: brake condition and fluid, reduction gear oil, cabin filter, tyres, coolant circuits, charging system and a full battery health report. EVs need less servicing than a petrol car, not none.

Hybrid Battery Health Report

Measures the state of health of every cell block in the high-voltage battery and gives you a written report. Essential before buying a used hybrid, and the honest way to find out whether a warning light means a single module or a whole new pack.

12V Battery Replacement (Hybrid & Electric)

Replaces the small 12V battery in a hybrid or EV, which wakes the car up and is nothing to do with the main drive battery. When it dies the car is completely dead even with a full charge, and people often fear the worst unnecessarily.

High Voltage Cable & Insulation Check

Inspects the orange high-voltage cabling and tests insulation resistance, which is the fault behind most hybrid and EV warning lights. Carried out by a technician qualified to work on high-voltage systems.

Regenerative Braking Check

Checks that regenerative braking is blending correctly with the friction brakes. Hybrid and EV brakes barely wear but do seize from lack of use, so this is paired with a physical brake inspection.

Inverter Coolant Change

Drains and refills the separate cooling circuit that keeps the inverter and drive electronics cool, which needs a specific bleed procedure to clear air locks. A scheduled item most owners have never heard of.

Charging Port Replacement

Replaces a damaged or faulty charging socket. Book this if the cable will not lock in, charging stops part-way through, or the port has been physically damaged.

You do not need to diagnose the car yourself

If the symptom is unclear, intermittent or affects more than one system, choose our Find The Fault service. We investigate the cause, explain it in plain English and price the right repair before parts are ordered.

Hybrid & Electric FAQs

What maintenance does an electric car still need?

Tyres, friction brakes, suspension, steering, cabin filters, wipers, lights, 12V battery and vehicle-specific coolant or reduction-gear items still need inspection or service.

Why can a charged EV still fail to start?

The small 12V battery powers control units and contactors that connect the traction battery. If it is weak, the car may not wake up.

Can I inspect high-voltage cables myself?

Only visually from a safe distance. Do not touch, disconnect, probe or remove covers from orange cables or high-voltage components.

Can SSK Mechanics do this at my home or workplace?

Many hybrid & electric jobs are mobile. Services needing a vehicle lift, controlled workshop equipment or high-voltage isolation are marked as workshop jobs; where available, SSK arranges collection and return.

What if I choose the wrong service?

If you cannot confidently match the symptom to a job, choose Find The Fault instead. The technician investigates the cause and explains the correct repair before parts are ordered, helping you avoid paying for a guessed part.
