📖BYD Song Plus: global hit family SUV demanding structured multi-powertrain care

BYD Song Plus (2021-2023)

The Song Plus became a pivotal global success for BYD, establishing the brand's international reputation with its sophisticated design, spacious family interior and versatile powertrain options. Maintaining this popular family SUV calls for comprehensive BYD Song maintenance, tailored to whether the vehicle is a DM-i hybrid or pure EV.

Engineering choices range from pure electric models with a 71.7 kWh pack to DM-i and twin-motor DM-p hybrids featuring a 1.5-litre engine and structural Blade Battery. Drive delivery is handled by an electric drive unit or EHS transmission, with battery pack longevity ensured by an integrated heat pump and cooling loop.

When shopping for a pre-owned Song Plus, inspect front tyres for shoulder wear caused by instantaneous electric torque. Check that transitions between electric and petrol drive are completely smooth on DM-i variants, test DC rapid charging speed on pure EV editions, and verify that the rotating touchscreen has received the latest software patches.

Owner notes

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

Reassuring points

Reliability
  • Internationally acclaimed family SUV combining stylish design, premium cabin appointments and quiet road manners.
  • Benchmark LFP Blade Battery technology providing exceptional thermal safety and extended cycle life.
  • Frugal DM-i hybrid option delivering outstanding real-world fuel economy and long total touring range.

Chronic weak spots

Keep an eye on
  • Front tyre inner edge wear: heavy SUV mass and immediate electric torque accelerate tyre wear; inspect tracking.
  • Engine oil fuel dilution on DM-i: ensure hybrid models embark on regular longer journeys to clear condensation from oil.
  • Rear brake disc corrosion: regenerative braking reduces friction brake usage; check rear discs for rust pitting.
  • OTA software update currency: confirm that vehicle firmware is up to date to resolve minor touchscreen glitches.

Critical deadlines

Do not miss
  • Initial engine service (DM-i models): complete break-in engine oil and filter change at 3,500 km or 6 months.
  • Routine engine oil renewal: replace 0W-20 synthetic engine oil every 10,000 km or 12 months on hybrid variants.
  • Brake fluid service: flush DOT 4 hydraulic brake fluid every 40,000 km or 24 months.
  • High-voltage cooling loop check: inspect thermal management fluid levels and pump function every 24 months.
