Jeep Grand Cherokee maintenance: the schedule, the costs, the traps
A midsize 2-row SUV with a gas powertrain. Below: the service intervals with real cost ranges, the repairs Grand Cherokee owners actually report, and when a fleet operator would sell. Same data Carlyle uses to score fleet buys.

When the smart money sells
On fleet math, 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.
