BYD Sealion 6 maintenance cost — service schedule, wear items, and yearly total (2026)

BYD Sealion 6 service schedule and what each visit covers

The visit covers a multi-point inspection, brake-fluid check, coolant top-up on the high-voltage cooling loop, software updates, and a 12 V battery test. Most owners are in and out in half a day at a cost that lands around the mark for the visit itself. BYD the country's service book for the BYD Sealion 6 is generally easy to follow and the workshop network is set up to handle it efficiently.

Wear items on the BYD Sealion 6

Plan the BYD Sealion 6's wear-item budget around tyres first; everything else is a smaller share. The BYD Sealion 6 weighs in around 1890 kg, which is on the higher side for its body class, so tyres are the meaningful wear-item line on the budget — expect a set every 35,000–50,000 km depending on driving style. Brake pads, by contrast, often last well beyond what they would on an equivalent petrol car because regen on the BYD Sealion 6 handles most of the deceleration. Wipers, cabin filter, and washer fluid are negligible items but worth keeping on a yearly checklist.

BYD Sealion 6 battery cost and warranty

EVs are a long-game purchase, and the BYD Sealion 6's battery warranty is the long-game line item to read first. The BYD Sealion 6 ships with a 71.8 kWh pack and a 8-year battery warranty (often paired with a kilometre cap), which covers most of the realistic ownership horizon. Field data on similar packs shows modest degradation under normal use — typically 5–10% capacity loss in the first four years. That curve is shallower if you keep the daily charge cap at 80% and avoid frequent DC fast-charging sessions.

BYD Sealion 6 five-year ownership maths
