Cost to keep
What it costs to own, by how long you keep it
Scheduled servicing only, from a brand-new Wrangler 4xe at 12,000 miles a year. Insurance, fuel, tires and depreciation are yours to add - this is the part the shop charges you for.

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 Wrangler 4xe is known for is Death wobble & oil filter housing leak (shared Wrangler faults) from about 40,000 miles ($200-$1,500). It is a range, not a certainty - but it is the number to have in your head at the dealership.
Operator notes
Plug-in hybrid: 2.0L turbo-four + two e-motors + ~17.3 kWh battery, ~21-22 mi electric range; DOES get oil changes. Regenerative braking greatly extends pad/rotor life. Named most unreliable midsize SUV by Consumer Reports; dominated by the multi-round HV-battery fire recall. Stellantis discontinued the 4xe (Wrangler + Grand Cherokee) at the end of 2025, so 2025 is the final model year.
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 phev Wrangler 4xe retires around 150,000 miles - but the exit window opens earlier here: Death wobble & oil filter housing leak (shared Wrangler faults) risk window ($200-$1,500) 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.
