BYD Seal maintenance cost — service schedule, wear items, and yearly total (2025)

BYD Seal service schedule and what each visit covers

BYD Seal owners typically see a workshop once a year for the scheduled visit and once more for tyres or wear items. On the BYD Seal, the recommended interval is typically annual or at a fixed kilometre count — whichever comes first. 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 Seal is generally easy to follow and the workshop network is set up to handle it efficiently.

Wear items on the BYD Seal

Tyres, wipers, brake pads — that's where the BYD Seal's real ongoing cost lives. The BYD Seal weighs in around 2150 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 Seal handles most of the deceleration. Wipers, cabin filter, and washer fluid are negligible items but worth keeping on a yearly checklist.

BYD Seal battery cost and warranty

For the BYD Seal, battery degradation over the warranty window has been modest in field data. The BYD Seal ships with a 82.56 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 Seal five-year ownership maths

Putting the BYD Seal numbers together: of scheduled maintenance, plus tyres amortised at roughly per year for moderate-mileage BYD Seal owners, plus insurance, plus energy at /km. For a BYD Seal owner driving 12,000 km a year, that all-in figure typically lands well below the running cost of a similar petrol car — and the gap widens as fuel prices rise.

Practical next steps

Use the original brand workshop for the BYD Seal's annual visit while warranty applies. Out of warranty, a certified EV specialist often beats them on price for the same work.
