📖BYD Song facelift: transition crossover bridging turbocharged petrol and EV eras

BYD Song (facelift 2018) (2018-2019)

The 2018 facelift revitalised the Song with BYD's bold 'Dragon Face' grille and introduced the all-electric EV500 alongside conventional turbocharged petrol options. Keeping this transitional compact crossover reliable calls for targeted BYD Song maintenance, reflecting whether the vehicle is combustion-powered or fully battery electric.

Petrol variants retain the 1.5-litre turbo engine paired with a six-speed dual-clutch gearbox, whereas the EV500 adopts a 62 kWh high-voltage battery driving a front electric motor through a single-speed reduction gearbox. Both models utilise an active liquid cooling system to maintain optimum operating temperatures under heavy load.

When inspecting a used 2018 Song, tailor your checks to the powertrain: test petrol models for smooth DCT clutch take-up and clean turbo boost, or verify fast-charging speeds and battery health diagnostics on the EV500. On all models, inspect front tyre shoulders and check front suspension wishbones for bushing wear.

Owner notes

The reassuring points, known weak spots and deadlines you should not let slip.

Reassuring points

Reliability
  • Contemporary 'Dragon Face' front styling with upgraded LED headlights and modernised interior appointments.
  • EV500 electric variant offering practical zero-emission range and low routine running costs.
  • Spacious five-seat cabin with generous rear legroom and versatile split-folding rear seats.

Chronic weak spots

Keep an eye on
  • DCT transmission calibration (petrol): check for low-speed clutch hesitation or jerky gear engagement in traffic.
  • EV500 fast charging consistency: test DC rapid charging to ensure full power delivery without early thermal throttling.
  • Front suspension control arm bushings: inspect lower wishbones for split rubber bushes and steering play.
  • Auxiliary 12 V battery condition: test battery voltage on EV models to prevent waking electronics errors.

Critical deadlines

Do not miss
  • Petrol engine oil and filter: renew synthetic engine oil every 7,500 to 10,000 km or 12 months.
  • Brake fluid replacement: drain and flush DOT 4 brake fluid every 40,000 km or 24 months on all variants.
  • EV reduction gearbox lubricant: inspect fluid level at 40,000 km; renew reduction oil at 60,000 km.
  • Cooling system flush: drain and refill liquid coolant loops every 40,000 km or 24 months.
