Cost to keep
What it costs to own, by how long you keep it
Scheduled servicing only, from a brand-new Escalade IQ 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 | $95 | $8 |
| 3 years | 36,000 mi | $2,660 | $74 |
| 5 years | 60,000 mi | $5,320 | $89 |
| 7 years | 84,000 mi | $5,685 | $68 |

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 Escalade IQ is known for is HV Ultium battery (200+ kWh) degradation / pack replacement from about 100,000 miles ($20,000-$40,000+). It is a range, not a certainty - but it is the number to have in your head at the dealership.
Operator notes
Battery-electric - NO oil changes. Scheduled maintenance is tires, cabin filter, brake fluid and long-interval battery/inverter coolant. Regen braking makes pads/rotors last 100k+. 200+ kWh Ultium pack, 800V DC fast charging, ~460 mi range. Extreme curb weight accelerates tire and air-suspension wear (biggest running cost). HV battery 8-yr/100k warranty. Launched MY2025.
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 Escalade IQ retires around 150,000 miles - but the exit window opens earlier here: HV Ultium battery (200+ kWh) degradation / pack replacement risk window ($20,000-$40,000+) opens ~100,000 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.
