Jeep Wrangler JL (4th Generation)

2018–2026 · JL · suv

First Wrangler with a turbocharged 4-cylinder (2.0L Hurricane) and a short-lived 3.0L EcoDiesel option (2020-2023) alongside the 3.6L Pentastar V6 and an eTorque mild-hybrid variant. The 470hp 6.4L Hemi 392 launched 2021. The 4xe plug-in hybrid arrived 2021 and became one of the best-selling PHEVs in the US. Notable for the 'death wobble' steering issue that follows every Wrangler generation.

Watch out: Death wobble — front-end shimmy under braking on certain tire sizes, even stock. Mopar TSB 22-002-19 addresses steering damper replacement; many owners report recurrence within months. Lifted JLs see it worse.
