All Known Issues

Intrusive ADAS (Safety Beeps)

MinorElectrics & Electronics

The driver assistance systems, particularly Lane Keep Assist and the Speed Limit Warning, can be overly sensitive and provide frequent audible alerts.

Est. Repair Cost: £0 (Software updates)

Infotainment Ergonomics & Lag

MinorElectrics & Electronics

The lack of physical buttons means almost all functions (including climate) are in menus, which can occasionally lag or feel unintuitive while driving.

Est. Repair Cost: £0 (Software fix)

Suspension Body Roll

MinorSuspension & Chassis

The suspension is tuned for comfort, which can lead to significant body roll and an unsettled feeling on undulating B-roads.

Est. Repair Cost: £0 (Design trait)

Poor Motorway Range Efficiency

MinorElectrics & Electronics

The Dolphin loses range rapidly at motorway speeds due to its boxy aerodynamics and small battery. Real-world motorway range can be 30-40% less than the official figure, making long-distance trips challenging.

Est. Repair Cost: £0 (Design trait)

Rapid Charging Speed Limitations

MinorElectrics & Electronics

The Dolphin's maximum DC charging speed is relatively modest (around 65kW), and the charging curve drops off quickly, meaning public rapid charging takes longer than many rivals.

Buying Tips for 2024 BYD Dolphin

  • The smaller 44.9kWh battery suits urban use but has noticeably less range on motorways
  • All four trims (Active, Boost, Comfort, Design) now available; choose battery size based on driving needs
