New Vehicle & Powertrain Warranty
The BYD DOLPHIN is covered by a comprehensive guarantee program. The official BYD Dolphin factory warranty is 6 years or 150,000 km, whichever occurs first, for every new vehicle. This period commences on the date of first registration, although in Western Australia, it begins from the date of delivery. The electric drive unit, which consists of the drive motor and drive motor controller, is covered for 8 years or 160,000 km.
In addition to the primary vehicle coverage, specific components possess separate warranty periods. The 12V lead acid starting battery is covered for 12 months or 20,000 km. The emergency charging and discharging device, which encompasses the AC charging connection device and the discharge connection device, carries a 12-month warranty. For items like paint application defects, such as overspray, low gloss, colour mismatch, or runs, the warranty period is 1 year. To understand exactly how these terms apply to your vehicle, refer to the official owner’s manual.
When calculating the final BYD Dolphin driveaway price in Australia, buyers should note that the warranty is a standard inclusion, but determining exact costs requires evaluating state-specific charges. Always consult an authorised BYD dealer for precise pricing and warranty terms.
Battery Warranty & Maintenance Requirements
The BYD Blade Battery is a core component of the vehicle. Depending on the variant, the BYD Dolphin battery capacity is 44.9 kWh in the Essential or 60.48 kWh in the Premium. The traction battery is backed by an 8-year or 160,000 km warranty, whichever occurs first, with a guarantee that it will retain at least 70% of its capacity over this period. If a valid claim is made, BYD may repair or replace the unit with a new, reconditioned, or remanufactured part at its sole discretion.
Proper battery care is mandatory to preserve this coverage. The manufacturer requires owners to keep the power battery at a 40% to 60% state of charge when the vehicle is unused for more than 7 days. If the vehicle sits unused for more than 3 months, you must fully charge it and then discharge it back to the 40% to 60% range every 3 months. The vehicle must be recharged promptly if the state of charge drops to 0%, as damage resulting from a failure to do so is not covered. It is recommended to fully charge at least once a week. A full charge from below 10% via AC charging every three to six months aids range estimation. In temperatures below 10 degrees Celsius, charge the vehicle right after use.
For inquiries regarding the BYD Dolphin battery thermal management, heat pump functions, or the complete list of charging procedures, refer to the official owner’s manual.
Warranty Exclusions & Voiding Conditions
Certain conditions and actions can void the warranty cover entirely. The handbook excludes damage caused by normal wear and tear, accident damage, flood damage, or water ingress resulting from deep-water wading. Using the vehicle for racing, or loading and towing beyond the stated capacities, will also invalidate the coverage. Any towing capacity limits are not given in the official facts and are determined by state regulations and towbar design, so you must confirm with BYD Automotive Australia before fitting any towing equipment.
Unauthorised modifications or third-party conversions will void the warranty. This includes software alterations, aftermarket ECU tuning, or bypassing the battery management systems. As the BYD DOLPHIN is a pure electric vehicle, it features no engine, no exhaust, and no spark plugs. The brand has no gas program, meaning any aftermarket LPG or autogas conversion is unsupported and will strictly void the manufacturer warranty. Furthermore, any failure to service the vehicle strictly per the manufacturer’s recommendations will compromise your coverage.
Service Schedule & Record Keeping
Maintaining an accurate service record is a strict requirement of the warranty terms. The official servicing schedule dictates that maintenance is due every 20,000 km or 12 months, whichever comes first. Subsequent intervals are 40,000 km or 24 months, 60,000 km or 36 months, 80,000 km or 48 months, 100,000 km or 60 months, and 120,000 km or 72 months. Under severe operating conditions, these intervals may need to be shortened.
During these visits, specific items are recorded in the handbook service record. For this pure electric model, the recorded maintenance items include replacing the brake fluid and replacing the e-motor controller coolant. You must keep all logbook records, receipts, and the warranty book as proof of maintenance. Any work carried out by anyone other than an authorised BYD Service Centre is not covered under the official warranty. For a detailed maintenance breakdown and inspection items, consult an authorised BYD dealer.
High-Voltage System Safety
The BYD DOLPHIN operates on a high-voltage electrical architecture, powering the permanent magnet synchronous motor that delivers front-wheel drive performance. The system manages the DC charging inputs, where the BYD Dolphin DC fast charging rate via CCS2 is 60 kW for the Essential trim and 80 kW for the Premium trim.
Due to the extreme electrical hazard, all dangerous work, including maintenance on the high-voltage system, brakes, steering, airbags, and ADAS calibration, must be done by an authorised BYD dealer or a qualified technician. The high-voltage orange cables present throughout the vehicle must not be touched or opened by owners under any circumstances. If the vehicle requires charging hardware repairs, or if you encounter issues when using the BYD Dolphin V2L camping adapter for running appliances, you must refer the diagnosis to qualified personnel.
Servicing Network & Genuine Parts
BYD vehicles in Australia are sold and serviced through BYD Experience Centres and authorised BYD service centres. The national retail partner is Eagers Automotive Limited, and the service network covers the Australian states and territories. For exact locations, owners should use the official online dealer locator.
When purchasing replacement parts, the warranty terms stipulate that genuine spare parts imported by BYD Australia, bought by owners, and installed by an authorised BYD Retailer are covered for 12 months from the date of purchase. Using non-BYD genuine or non-recommended parts that cause damage is explicitly excluded from the warranty. Consumable items, for which a charge may be made, include fluids, wheel alignment and balancing, tyres, brake linings, wiper blades, transmitter batteries, gas struts, and body rattles or squeaks after 12 months or 20,000 km. Note that tyres are not covered by the BYD warranty; they are subject to the tyre manufacturers’ warranties. All replacement parts and installation procedures are subject to manufacturer specifications.
