The Jeep Wrangler (JL) has been built since 2018.
For this generation we cover 2 engines and 7 known faults, each with the mileage range where it usually appears.
The most expensive known risk is EGR / DPF: it usually appears at 100,000–180,000 km and costs €300–1,500 to fix.
In UK roadworthiness tests in 2024, at 0–50 thousand km this model most often failed on: lights, wipers and visibility (4.4 %), tyres and wheels (1.2 %), exhaust, emissions and leaks (1.1 %). It fails more often than an average car of the same age and mileage on: suspension, body and corrosion, exhaust, emissions and leaks. It fails less often than average on: brakes, tyres and wheels.
