Cost to keep
What it costs to own, by how long you keep it
Scheduled servicing only, from a brand-new Grand Cherokee 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 | $125 | $10 |
| 3 years | 36,000 mi | $1,055 | $29 |
| 5 years | 60,000 mi | $2,235 | $37 |
| 7 years | 84,000 mi | $2,565 | $31 |
| 10 years | 120,000 mi | $4,940 | $41 |
| 15 years | 180,000 mi | $7,175 | $40 |
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 Grand Cherokee is known for is 3.6 Pentastar rocker/lifter tick from about 40,000 miles ($2,000-$5,000). It is a range, not a certainty - but it is the number to have in your head at the dealership.
Operator notes
Current WL generation, gas 3.6 Pentastar (timing CHAIN). Oil 10k synthetic / 5k severe. Air-ride and Uconnect are the big-ticket watch items; ZF 8-speed is durable if serviced ~60k.
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 Grand Cherokee retires around 95,000 miles - but the exit window opens earlier here: 3.6 Pentastar rocker/lifter tick risk window ($2,000-$5,000) 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.
