📖BYD Yuan EV: accessible early compact electric SUV requiring attentive chassis care

BYD Yuan EV (2020-2021)

The Yuan EV preceded BYD's global expansion, offering motorists a compact, accessible electric crossover designed for economical urban commuting and low running costs. Keeping this early EV dependable calls for structured BYD Yuan maintenance, paying close attention to battery charging habits and suspension wear.

Equipped with a 53.2 kWh high-voltage battery, it drives the front wheels via a quiet electric motor and an integrated reduction gearbox. Battery temperatures are maintained by an active liquid cooling system, while mechanical deceleration is handled by front and rear discs supported by regenerative braking.

When shopping for a pre-owned Yuan EV, test DC rapid charging to confirm consistent charging speeds without premature thermal drop-offs. Inspect front wishbone bushes and drop links for wear over speed humps, check rear brake discs for corrosion from light usage, and verify that the 12 V auxiliary battery holds steady charge.

Owner notes

The reassuring points, known weak spots and deadlines you should not let slip.

Reassuring points

Reliability
  • Accessible purchase price providing budget-friendly entry into all-electric crossover motoring.
  • Dependable electric powertrain with low routine servicing costs and no combustion engine fluids.
  • Compact exterior dimensions making city parking and tight suburban driving effortless.

Chronic weak spots

Keep an eye on
  • Front suspension bushing wear: inspect lower control arm bushes and drop links for play over city potholes.
  • DC rapid-charging performance: test charging power on public chargers to ensure battery accepts full current.
  • Auxiliary 12 V battery condition: test low-voltage battery annually to prevent unexpected vehicle immobilisation.
  • Rear brake disc oxidation: clean brake disc faces through regular firm braking to prevent caliper slider seizure.

Critical deadlines

Do not miss
  • Annual inspection service: complete multi-point safety check and diagnostic scan every 15,000 to 20,000 km or 12 months.
  • Brake fluid replacement: drain and flush DOT 4 hydraulic brake fluid every 24 months or 40,000 km.
  • Reduction gearbox fluid service: inspect drive unit lubricant level at 40,000 km; replace fluid at 60,000 km.
  • High-voltage cooling system check: inspect battery and inverter coolant levels and pump operation every 24 months.

Frequently asked questions about BYD Yuan EV

What servicing does an electric BYD Yuan EV need?▾
On a fully electric BYD Yuan EV, periodic servicing is mainly a general inspection, an electrical-system check and a traction-battery diagnosis, plus brakes, tyres and the MOT. Garajo groups these checks and reminds you of each due date, for free.
How often should you check the electrical system and the battery?▾
The usual benchmark is every 15,000 km or 1 year, with a traction-battery diagnosis on the same rhythm (15,000 km / 1 year).
When should you change the battery coolant on a Yuan EV?▾
Garajo shows 120,000 km or 10 years. The interval can vary by manufacturer: always confirm in the handbook.
Does an electric Yuan EV need an oil change or a timing belt?▾
No. Those jobs apply to petrol and diesel engines. On a fully electric version, maintenance focuses on the electrical system, braking, tyres and safety checks.
How much does it cost to service a BYD Yuan EV?▾
The service budget for a BYD Yuan EV sits in line with the market average. Allow about 130 € for a full service, for example. Garajo estimates your budget by powertrain and tracks what you actually spend, for free.
Which BYD Yuan EV powertrain is best for town use?▾
This model is only available as electric. In town, electric versions fit best thanks to energy recuperation and the absence of cold-start cycles.
Which BYD Yuan EV powertrain should you choose if you mostly drive on the motorway?▾
This model is only available as electric. On the motorway in an electric version, look for the longest range and strong DC rapid charging.
