How EVs and Automation Are Changing Vehicle Technician Work

Vehicle technicians are not about to be replaced by electric or automated cars. Their task mix is changing: less routine work on some combustion-engine components, more high-voltage safety, electronic diagnosis, sensor calibration, software-led fault finding and documented repair.

The change is real, but it is uneven. A workshop still has to support the vehicles that actually arrive, not the fleet imagined in a technology forecast.

What has changed already

Current evidence: The International Energy Agency reports that more than 20 million electric cars were sold globally in 2025, equal to one in four new-car sales. It also estimates that electric cars were only about 5% of the global car fleet at the end of that year.

Those two figures belong together. EV sales are growing, while the installed fleet remains mostly non-electric. For a working technician, that means a mixed-fleet transition rather than an overnight switch.

Battery-electric vehicles remove tasks associated with engine oil, exhausts, spark ignition and some mechanical transmission components. They introduce other work involving high-voltage isolation, battery and thermal-management systems, power electronics, regenerative braking and manufacturer diagnostic procedures.

Hybrids add another layer because they combine high-voltage equipment with an internal-combustion powertrain.

The strongest near-term signal is skills demand

The UK Institute of the Motor Industry reported in May 2026 that 74,734 technicians held an EV qualification, around 35% of the UK technician workforce. Its model projects that demand could exceed supply by more than 43,000 technicians by 2035.

Evidence boundary: That shortfall is an IMI forecast, not a known future fact. It depends on EV uptake, workforce size, qualification rates and the model's assumptions. The current qualification count is evidence; the 2035 gap is a scenario to plan against.

The practical conclusion is still strong. High-voltage work cannot be treated as ordinary mechanical work with a new connector. Employers need role-appropriate competence, safe systems of work, suitable equipment and clear limits on who may inspect, isolate or repair a vehicle.

“Self-driving” needs a reality check

The previous version of this article described autonomous vehicles as though broad consumer adoption were close and technicians would soon need to maintain fleets of fully driverless cars.

That was too certain.

Current evidence: The US National Highway Traffic Safety Administration says the highest automation currently available in consumer vehicles still requires driver engagement and attention. It distinguishes driver-assistance features from automated driving systems that can perform the entire driving task.

Great Britain has a legal framework for automated vehicles, but the Automated Vehicles Act implementation programme is still being put into operation. The government opened applications for limited automated passenger-service pilots in 2026, while full implementation of the Act is intended for the second half of 2027.

This matters because advanced driver-assistance systems, known as ADAS, are already workshop work. They include cameras, radar, braking assistance, lane support and related control units. Fully driverless consumer cars are not the baseline technicians should plan around today.

The workshop tasks most likely to grow

Inference from current vehicle and workforce evidence: The following capabilities should become more useful as the fleet changes:

high-voltage hazard awareness and vehicle isolation
battery health, charging and thermal-system diagnosis
electrical measurement and fault tracing
ADAS inspection and calibration after relevant repairs
interpreting diagnostic trouble codes without blindly replacing parts
checking software versions, service bulletins and manufacturer procedures
explaining technical findings and repair boundaries to customers
recording evidence for warranty, safety and handover

This is not a claim that every technician must become a software engineer. Most workshop value will still come from disciplined diagnosis, safe physical work and judgement about interacting systems.

AI will assist diagnosis, not accept responsibility

AI may help classify symptoms, search technical information or highlight patterns in vehicle data. Connected vehicles may also report faults before a booking.

Inference: These tools could reduce the time spent searching for a known fault pattern. They may also create new failure modes: confident but wrong suggestions, incomplete service history, inaccessible manufacturer data and over-reliance on a diagnostic recommendation.

A technician still has to verify the evidence on the vehicle, follow an approved procedure and decide whether the repair is safe. Do not enter customer identifiers, vehicle-location history or confidential workshop data into an AI service unless its use has been approved.

A practical plan for technicians and workshop owners

Measure the real vehicle mix. Review jobs from the last six months by powertrain and task. Do not build a skills plan from national sales headlines alone.
Map capability, not attendance. Record who can safely perform awareness, isolation, diagnosis and repair work, and what evidence supports that judgement.
Prioritise the next recurring task. That may be EV isolation, battery cooling, ADAS calibration or electrical diagnosis. Choose from actual work and lost bookings.
Check equipment and information access. Competence without insulated tools, test equipment, technical data or a safe work area is not operational capability.
Run supervised jobs. Verify the complete process from booking and risk assessment through diagnosis, repair, quality check and customer handover.
Review quarterly. Compare the plan with the vehicles, faults and outsourced work now appearing in the workshop.

What can we forecast responsibly?

Forecast: EVs and ADAS are likely to take a larger share of workshop activity as newer vehicles move through the fleet. The pace will vary by country, vehicle age, customer base, regulation and manufacturer support.

We cannot responsibly promise that mechanics will become “technology specialists”, that ownership will collapse, or that autonomous fleets will create a particular number of repair jobs by a fixed date.

The safer conclusion is also more useful: follow the task mix, build verifiable competence and keep the workshop capable of serving both the present fleet and the next one.
