Xiaomi SU7 Service Intervals at a Glance — Quick Answer

Short answer: Xiaomi SU7 routine service every 12 months or 20,000 km, whichever first. Cabin filter and 12V battery are the only items you'll touch in year 1. Two things actually matter beyond that: replace 12V at year 3, replace brake fluid every 2 years.

Service interval table

| Mileage / Time | What happens |

|----------------|--------------|

| 5,000 km / 3 mo | First inspection (no parts) |

| 20,000 km / 12 mo | Cabin filter, 12V check, tyre rotation, brake pad inspection, software update |

| 40,000 km / 2 yr | Above + brake fluid replacement (DOT 4 LV — brake-by-wire spec) |

| 60,000 km / 3 yr | Above + 12V battery replacement (preventative) |

| 80,000 km / 4 yr | Above + A/C service + suspension inspection |

| 100,000 km / 5 yr | Above + cabin filter, possibly first front brake pads |

| 160,000 km / 8 yr | Coolant flush (low-conductivity) |

Two things that matter

1. 12V battery at year 3. Don't wait for the warning light. Xiaomi's parasitic draw from constant-on Mi services drains AGM 12V batteries faster than legacy EVs.

1. Brake fluid every 2 years. Xiaomi SU7 uses DOT 4 LV (low viscosity, brake-by-wire spec). Don't substitute standard DOT 4. Hygroscopic fluid loses pedal feel above 3% water content.

What you can ignore (compared to ICE service lists)

No engine oil, no spark plugs, no engine air filter, no timing belt, no transmission fluid (single-speed reducer per axle, sealed). If a workshop bills for these, push back.

5-year cost expectations (EU averages, 2026)

• 5-year total: ~€1,000-1,450 for routine service
• Comparable petrol sedan (BMW 3 Series, Audi A4): €3,500-4,800
• Savings vs petrol: ~€2,500-3,400 over 5 years

Wear items

• Brake pads: front 60,000-90,000 km thanks to regen. Rear often lifetime.
• Wiper blades: 12 months
• 12V battery: 3 years (proactive replacement recommended)
• Tyres: 25,000-40,000 km on the Performance trim

Common mistakes

1. Standard DOT 4 instead of DOT 4 LV (brake-by-wire system needs low viscosity).
2. Generic universal cabin filter.
3. Ignoring 12V check until year 4 (already failing by then).
4. Letting workshop service the sealed reducer.
5. Generic coolant for top-up.

FAQ

How often should the Xiaomi SU7 be serviced?

12 months / 20,000 km. Drop to 15,000 km in hot or salt-belt climates.

What brake fluid does it use?

DOT 4 LV (low viscosity), brake-by-wire spec. Don't substitute standard DOT 4.

How long do brake pads last?

Front 60,000-90,000 km. Rear often lifetime.

Should I replace the 12V proactively?

Yes — at year 3. Xiaomi's parasitic draw is heavier than legacy EVs.

Cheaper than a BMW 3 Series?

50-65% cheaper over 5 years.
