A compact luxury crossover SUV with a gas powertrain. Below: the service intervals with real cost ranges, the repairs QX50 owners actually report, and the mileage windows worth buying ahead of - whether you are keeping it for yourself or putting it to work.

Known repair windows
What QX50 owners actually run into
Mileage ranges where these repairs typically show up. Buying above a window is not automatically a pass - it just needs to be priced in.

Cost to keep
What it costs to own, by how long you keep it
Scheduled servicing only, from a brand-new QX50 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 | $115 | $10 |
| 3 years | 36,000 mi | $955 | $27 |
| 5 years | 60,000 mi | $2,160 | $36 |
| 7 years | 84,000 mi | $2,640 | $31 |
| 10 years | 120,000 mi | $4,445 | $37 |
| 15 years | 180,000 mi | $6,480 | $36 |
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.
Beyond the schedule, the first big-ticket item this QX50 is known for is VC-Turbo engine bearing failure (recall) from about 40,000 miles ($8,000-$14,000 (engine)). It is a range, not a certainty - but it is the number to have in your head at the dealership.
Operator notes
Final model year 2025; US orders suspended April 2025 and line discontinued (tariff + demand). KR20DDET VC-Turbo 2.0L variable-compression I4 (268 hp) with Jatco CVT, FWD/AWD. Engine-bearing recall and CVT are the headline risks. 0W-20 synthetic; monitor for fuel dilution and change oil early. CVT fluid every ~30k despite 'fill-for-life' claim.
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 gas QX50 retires around 95,000 miles - but the exit window opens earlier here: VC-Turbo engine bearing failure (recall) risk window ($8,000-$14,000 (engine)) opens ~40,000 mi. 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.
