BMW i4 maintenance: the schedule, the costs, the traps
A compact luxury EV liftback (gran coupe) with a battery-electric powertrain. Below: the service intervals with real cost ranges, the repairs i4 owners actually report, and the mileage windows worth buying ahead of - whether you are keeping it for yourself or putting it to work.

Cost to keep
What it costs to own, by how long you keep it
Scheduled servicing only, from a brand-new i4 at 12,000 miles a year. Insurance, fuel, tires and depreciation are yours to add - this is the part the shop charges you for.
| You keep it | Odometer | Servicing | Per month |
|---|---|---|---|
| 1 year | 12,000 mi | $100 | $8 |
| 3 years | 36,000 mi | $600 | $17 |
| 5 years | 60,000 mi | $1,575 | $26 |
| 7 years | 84,000 mi | $1,775 | $21 |
| 10 years | 120,000 mi | $3,150 | $26 |
| 15 years | 180,000 mi | $4,725 | $26 |
Per-month can dip as the horizon lengthens - a major service lands in one year and then averages out across all the months after it. The left column is what you actually spend.
Operator notes
G26 BEV liftback; trims eDrive35/eDrive40/xDrive40/M50. In production, MY2026 current. Among the more reliable premium EVs (2024 ~78/100). NO oil changes; regen extends pad life. Rank issues are recall/software, not wear-out. Coolant loops for battery/electronics are long-life.
When the smart money sells
Keeping it yourself, there is no cutoff - the table above runs to fifteen years. On fleet math, where a car has to keep earning, a battery-electric i4 retires around 150,000 miles. Carlyle's garage tracks this per car, against your actual odometer.
Cost ranges are typical US independent-shop estimates and vary by region and condition. Modeling, not mechanic advice - always confirm against your car's service records.
