Separately, Jeep issued TSB 23-079-23 addressing steering-wheel shimmy on 2018-2020 JLs built on or before August 11, 2020, with a revised steering damper as the fix. As with the JK, most death-wobble cases trace to a worn track bar, tie rod, ball joints, or steering damper rather than a structural defect. TSB 23-079-23 (steering damper); NHTSA Preliminary Evaluation into 2018-2019 frame welds (no recall issued). Typical cost: Free if covered under warranty/TSB; $200-$800 for track bar/damper/tie-rod replacement out of warranty. ### Manual-transmission clutch pressure plate overheating (recall) (major) On 2018-2020 JLs (and 2020 Gladiators) with the 6-speed manual, the clutch pressure plate can overheat through friction and fracture, potentially cracking the transmission case and allowing hot debris to reach an ignition source, a fire risk. Jeep recalled roughly 33,200 vehicles; warning signs include a burnt-clutch smell or abnormal pedal travel before failure. Dealers replace the clutch kit (pressure plate and disc) under the recall at no cost. NHTSA 20V-124 (FCA/Jeep internal number W12). Typical cost: Free under recall. ### 3.6L Pentastar oil cooler / filter housing cracking (moderate) Same issue as the JK generation: the plastic oil-cooler/filter-housing bolted to the front of the Pentastar V6 can crack and leak oil, especially as the vehicle ages. Watch for oil odor, drips near the front of the engine, or falling oil level between changes. Typical cost: $150-$400 DIY; $400-$900 at a shop. ### 2.0L turbo ("Hurricane 4") oil consumption and timing chain tensioner wear (moderate) Owners of the 2.0L turbo four report above-normal oil consumption in some cases (attributed to turbo seal/piston ring wear) and premature timing chain tensioner wear producing a rattle on cold start that can worsen into chain noise if ignored. Keep an eye on the dipstick between changes and address any cold-start rattle promptly, a stretched/rattling chain can jump time if left unaddressed. Typical cost: $0 (top-offs) to $1,500-$3,000 for tensioner/chain work. 1 more issue is reported in other 2018-2025 years: 4xe high-voltage battery internal failure / fire risk (recall) (2021-2023 (4xe only, specific battery-cell production window)).

Early JLs drew an NHTSA investigation into frame-weld quality tied to steering shimmy, a 2018-2020 manual-transmission clutch recall, and (on 4xe only) a high-voltage battery fire recall. Across both generations, tire size is trim-dependent, Rubicon ships on 33-inch mud-terrains from the factory, and the Xtreme Recon package puts genuine 35s under a Rubicon or 392 with no lift required, and off-road use accelerates wear on track bars, ball joints, and diff/transfer-case fluid compared with a Wrangler that never leaves pavement.
