Frame, fuel system and instrument cluster on the Wrangler JLKnown weak points

Engine / equipment: Jeep Wrangler JL (2.0 Turbo, 2.2 Multijet and 4xe)
Period mentioned: 2018 onwards
Symptoms: Front track-bar brackets badly welded that can separate from the frame (2018–2019); a badly welded intermediate steering shaft (2018) and mis-machined column shaft (2019); a 2.0 Turbo fuel-line connector that cracks and leaks petrol (2020); a frame stud that can puncture the tank in a crash (2020–2022); an instrument cluster that goes blank from an internal short (2018–2024).
Possible cause described: Manufacturing defects documented by US recalls (NHTSA 18V-675, 18V-343, 19V-201, 21V-665, 23V-191 and 24V-652). European cars may have equivalent campaigns: check by VIN.
Check for the garage: Check campaigns by VIN; look for a fuel smell on the 2.0 Turbo; check the track-bar welds.

Engines: 4xe (Plug-in hybrid)

Jeep 4xe batteryHigh-voltage battery

Engine / equipment: Jeep Wrangler 4xe and Grand Cherokee 4xe (plug-in hybrids)
Period mentioned: 2020–2025
Symptoms: Usually none. In rare cases, a battery fire, including when parked.
Possible cause described: Some cells may have a damaged internal separator. Stellantis has run several recalls since 2023, the latest in the US for about 320,000 cars; until a fix is available it asks owners not to charge them and to park outside. The repair is a software update and, if needed, a battery replacement.
Check for the garage: Confirm the recall status by VIN; if one is open with no fix, do not charge and park away from buildings.
