Official Warranty Coverage

Regarding the BYD SEAL vehicle warranty coverage details, the standard new vehicle guarantee spans 6 years or 150,000 km, whichever occurs first. This period commences on the date of first registration, or from the date of delivery in Western Australia. Specific components carry shorter coverage periods. For instance, the lead acid starting (12V) battery is covered for 12 months or 20,000 km, whichever occurs first. Furthermore, paint application defects such as overspray, low gloss, or mismatch are covered for 1 year. The emergency charging and discharging device, which includes the AC charging connection device and discharge connection device, carries a 12-month warranty. Tyres are not covered by the BYD warranty; tyre manufacturers’ warranties apply. For any warranty claims, always consult an authorised BYD dealer.

Traction Battery & Drive Unit

The traction battery warranty covers the BYD Blade Battery (82.56 kWh) for 8 years or 160,000 km, whichever occurs first, guaranteeing a minimum 70 percent state of health (SOH). This identical period of 8 years or 160,000 km also covers the electric drive unit, which comprises the drive motor and drive motor controller. BYD may repair or replace these components with a new, reconditioned, or remanufactured part at its sole discretion. Maintaining the battery correctly is critical to preserve this coverage. Battery care instructions require keeping the power battery at a 40% to 60% state of charge when the vehicle is unused for more than 7 days. If unused for more than 3 months, it must be fully charged then discharged back to 40% to 60% every 3 months. Always refer to the official owner’s manual for complete battery maintenance guidelines.

Exceptions and Voiding the Cover

Certain actions and conditions will void the manufacturer warranty. The coverage does not extend to normal wear and tear, regular maintenance items, or odometer tampering. Any work performed by anyone other than an authorised BYD Service Centre will void the cover for the affected parts. Furthermore, unapproved modifications, third-party conversions, and alterations including software or ECU tuning are excluded. Because the BYD SEAL runs exclusively on a pure electric powertrain, aftermarket gas modifications such as LPG, CNG, or autogas conversions are strictly prohibited and will void the manufacturer warranty.

Damage resulting from racing, loading or towing beyond specifications, accidents, or water ingress from deep-water wading is also excluded. The warranty excludes damage caused by a failure to follow correct charging procedures, such as when utilising a 150kW DC fast charger via the CCS 2 port. Always subject to manufacturer specifications, the warranty demands strict adherence to the official servicing recommendations.

Servicing & Documentation

To maintain the warranty, owners must retain essential documentation, including the logbook, service receipts, the owner’s manual, and the Warranty and Service Handbook. Servicing is due at intervals of 20,000 km or 12 months, whichever comes first, up to 120,000 km or 72 months. Under severe operating conditions, intervals may need to be shortened. For the pure electric series, the service record items include replacing the brake fluid and the e-motor controller coolant.

Items for which a charge may be made include servicing items and fluids, wheel alignment and balancing, tyres, brake linings, wiper blades, transmitter batteries, gas struts, and body rattles and squeaks after 12 months or 20,000 km. To verify specific servicing tasks, confirm with BYD Automotive Australia or an authorised service centre. Buyers seeking an exact driveaway price in Sydney, Melbourne, Brisbane, or Perth must check directly with retail locations, as prices are not published in the official brochure.

High-Voltage System Care

The high-voltage system requires strict safety protocols. Dangerous work on the high-voltage system, brakes, steering, airbags, or ADAS calibration must be executed by an authorised BYD dealer or qualified technician. High-voltage orange cables must not be touched or opened by owners. For optimal battery health and accurate range estimation, a full charge from below 10% via AC charging every three to six months is advised. Furthermore, fully charging at least once a week is recommended. In temperatures below 10 degrees Celsius, charge the vehicle right after use. The vehicle must be recharged promptly if the state of charge drops to 0%, as damage from a failure to do so is not covered.
