Jeep Wrangler IV (JL) (2018 – 2025)

Reliability score : 7.2/10

The fourth-generation Jeep Wrangler (JL) marks a major evolution for the off-road icon. While retaining its rustic architecture (ladder frame, rigid axles) and timeless design, it takes a spectacular leap forward in terms of finish quality, ride comfort, and onboard technology. The introduction of the plug-in hybrid powertrain (4xe) has helped sustain the model in heavily taxed European markets, while North America received extreme versions like the Rubicon 392 (V8). A 2024 facelift brought a new grille, a standard 12.3-inch touchscreen, curtain airbags, and a full-float rear axle (Dana 44) on the Rubicon version. Although its off-road capabilities remain unmatched, its overall reliability is marred by temperamental electronics and numerous recalls, particularly on the 4xe version and dies

✅ Strengths

Exceptional off-road capabilities (especially in Rubicon trim)
Extremely low depreciation on the used market
Unique modularity (removable roof, doors, and windshield)
Highly responsive and intuitive Uconnect infotainment system
Generally very robust petrol engines (2.0T and 3.6 V6)

⚠️ Weaknesses

Poor soundproofing and wind noise on the highway
Vague road handling (recirculating ball steering) and average braking
Disastrous reliability of the electronics and battery on the 4xe version
Very high fuel consumption (unfavorable aerodynamics)
Purchase price has become prohibitive, especially in Europe

🎯 Verdict

The Jeep Wrangler JL is a passion-driven vehicle with extraordinary capabilities. If you are looking for reliability, absolutely favor the classic petrol engines (2.0T Hurricane or 3.6 V6 Pentastar) paired with the 8-speed automatic gearbox (ZF), which prove to be very robust in use. On the other hand, the 4xe plug-in hybrid version should be approached with extreme caution: although fiscally attractive, it accumulates serious early-production problems (battery fire risks, blocking software bugs). Similarly, the diesel versions (especially the 3.0 EcoDiesel) and manual gearboxes have suffered major recalls. Buying a used Wrangler requires a meticulous verification of the recall history (mandatory VIN check) and an inspection of the underbody.
