📖BYD Tang II facelift: flagship technological showcase demanding dedicated system care

BYD Tang II (facelift 2021) (2021-2025)

The 2021 facelift redefined the Tang II as BYD's high-tech executive showcase, introducing ultra-efficient DM-i and potent DM-p hybrid systems alongside upgraded pure-electric variants. Preserving this luxurious seven-seat SUV demands attentive BYD Tang maintenance, safeguarding advanced high-voltage systems and heavy-duty running gear.

Central to this generation is BYD's structural Blade Battery, powering dual-motor AWD layouts or working alongside a 1.5-litre turbo engine with an E-CVT transmission. Active thermal control is managed by a sophisticated heat pump and cooling circuit designed to handle high-output rapid charging and aggressive hill climbing without derating.

When assessing a used Tang II facelift, inspect all four tyres for balanced wear, as high vehicle mass combined with instant electric torque places heavy demands on rubber. Confirm that DC fast charging reaches full rated power, check that air conditioning blows cold across all three seating rows, and verify that all OTA software updates are current.

Owner notes

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

Reassuring points

Reliability
  • Benchmark Blade Battery technology offering superior fire safety and extended operational life.
  • Versatile luxury seven-seat interior with rotating 15.6-inch touchscreen and premium sound deadening.
  • Outstanding performance balance between frugal DM-i efficiency and blistering DM-p twin-motor speed.

Chronic weak spots

Keep an eye on
  • Four-wheel tyre consumption: heavy SUV mass and electric torque wear tyres rapidly; rotate every 10,000 km.
  • Air conditioning across rear rows: verify rear climate blower operation and refrigerant levels.
  • Brake disc corrosion: regenerative braking lightly loads mechanical brakes; make periodic firm stops to clean disc faces.
  • Rapid charging thermal management: ensure cooling fans operate quietly during high-power DC fast-charging sessions.

Critical deadlines

Do not miss
  • Engine oil and filter change (hybrid models): renew 0W-20 synthetic engine oil every 10,000 km or 12 months.
  • Hydraulic brake fluid service: flush DOT 4 brake fluid every 40,000 km or 24 months.
  • High-voltage battery diagnostic scan: perform comprehensive cell balance scan every 24 months.
  • Thermal management coolant inspection: inspect coolant circuits annually; flush fluid every 80,000 km or 4 years.

Which service markers apply to an electric Tang II (facelift 2021)?▾
On fully electric versions, plan an electrical-system and traction-battery check around 15,000 km / 1 year, and battery coolant around 120,000 km / 10 years (always confirm with the manufacturer).
What are the common problems on the Tang II (facelift 2021)?▾
Tang II (facelift 2021) owners should especially watch: Four-wheel tyre consumption: heavy SUV mass and electric torque wear tyres rapidly; rotate every 10,000 km. Air conditioning across rear rows: verify rear climate blower operation and refrigerant levels. Garajo includes these watch points so you can act early.
How much does it cost to service a BYD Tang II (facelift 2021)?▾
