A compact luxury coupe-crossover SUV with a gas powertrain. Below: the service intervals with real cost ranges, the repairs QX55 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 QX55 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.

Shares Jatco CVT with QX50; judder and eventual failure
Oil dilution / high oil consumption

Cost to keep
What it costs to own, by how long you keep it
Scheduled servicing only, from a brand-new QX55 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 QX55 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
Coupe-roofline sibling of QX50; launched 2021 (2022 MY), final model year 2025, discontinued alongside QX50. Same VC-Turbo 2.0L + Jatco CVT, but AWD is standard. Same engine-bearing recall and CVT risks as QX50. 0W-20 synthetic, monitor oil dilution, CVT fluid ~30k.
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 QX55 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.
