AITO M9  Maintenance and EV System Care at EVS in China

AITO M9 Maintenance and EV System Care at EVS in China

The AITO M9 is a large luxury SUV built around a smart cabin, advanced driver assistance and a choice of full-electric or extended-range drive. EVS will maintain every part of it, from high-voltage components and air suspension to software calibration and warranty-covered repair.

About AITO M9

About AITO M9.

The M9 is AITO's flagship: a six-seat luxury SUV offered as a battery-electric model and as an extended-range model in which a petrol engine acts only as a generator for the battery. It carries a dual-motor all-wheel-drive layout, air suspension, a large connected display setup and one of the more capable driver-assistance systems on the market, with sensors that need calibration after any work affecting ride height, glass or bumpers. At EVS we will service the M9 as one system rather than a set of parts: battery and thermal management, inverter and motor checks, suspension and brake service, generator maintenance where fitted, and the software work that keeps its assistance features accurate.

Frequently Asked Questions.

Battery health and thermal system checks, brake and suspension inspection, cabin and coolant filter service, driver-assistance calibration and software updates. Extended-range examples also need engine oil and filter service for the generator.

Yes. We will diagnose and repair air suspension faults, including compressor, strut and ride-height sensor issues, and we will recalibrate the driver-assistance cameras afterwards because a change in ride height moves their aim.

Yes. We will test the onboard charger, high-voltage cabling, battery modules and thermal management to find why range or charging speed has dropped, and we will give you the measured results rather than a guess.

We are. EVS carries out sensor calibration, camera and radar alignment and control-module updates for the M9's assistance features, which is essential after windscreen replacement or any front-end repair.

This brand in China

China ended 2025 with 43.97 million new-energy vehicles in use, and the China Automobile Maintenance Industry Association has been reported as counting only 20,000 to 30,000 workshops equipped for them against roughly 400,000 for petrol cars. Whatever you drive, the shortage is not of garages. It is of garages that can safely open a high-voltage system, read what it says, and complete the calibration afterwards.

What we expect to see

Four patterns, and most of the work is in them...

Four patterns account for most of the work on electric cars in a market like this one, and EVS workshops elsewhere see the same four. None of them is unusual. What is unusual here is how few workshops are equipped to tell them apart.

A battery quote that should have been a module

The first large out-of-warranty bills are arriving as the 2020-2023 cohorts leave cover. A pack is not always the answer: a single module, a contactor, a cooling circuit or a sensor can present the same way and cost a fraction. The difference is whether anyone measured before quoting.

Calibration nobody can complete

After a collision repair, a windscreen change or suspension work, the driver-assistance cameras and radar need recalibrating. Yicai Global has reported third-party repairers in Shanghai unable to obtain the data and equipment to do it. The car leaves looking finished, with its sensors pointing at the wrong place.

Thermal loss that never lit a warning

A cooling circuit running below par throws no fault code. It simply ages the pack, and the owner meets it two or three years later as range that will not come back. It is found by measuring coolant temperatures under load, not by reading codes.

A dead car with a full battery

No screens, no door unlock, no response - while the traction pack shows plenty of charge. It is the 12-volt battery, which wakes the car and which the high-voltage system cannot come on without. Cheap part, common failure, and it strands people who were told their car had 400 km left.

How a visit works

What this will look like when we open...

The Shanghai centre has not opened yet, so this is what we are building toward rather than what you can book today.

01

Tell us the symptom

Not the diagnosis. What the car is doing, when it started, and whether anything changed before it - a service, a collision, a software update, a cold week.

02

We measure before we quote

Fault codes say where the alarm went off, not why. Data streams, actuator tests and circuit measurements say why. The quote comes after that, not before.

03

You get the finding in writing

What is wrong, what it will cost, and what can wait. If a cheaper repair will do the job, that is the one we will put in front of you.

04

The work is verified, not just finished

Anything that needed coding gets coded. Anything that needed calibrating gets calibrated and recorded. A job that was not verified is a job that comes back.
