Repairs typically run $150-$1,200. Severity: high.

Severity: high.

What is the 2018-2024 Jeep Wrangler Steering Gear Box Loose Play & Highway Wandering (Aluminum-to-Steel Box TSB)?

JL Wranglers (and the related Gladiator) are widely reported to have vague, loose on-center steering that wanders and drifts at highway speed, forcing constant correction. This is distinct from death wobble — it is excessive play and tracking instability in the steering gear itse… Repairs typically run $0-$1,200. Severity: high.

What is the 2018-2024 Jeep Wrangler eTorque Belt-Starter Generator (BSG) / 48V Power Pack Failure — Charging & No-Start?

What is the 2017-2021 Jeep Wrangler Uconnect 8.4 Touchscreen Delamination — Bubbling, Ghost Touches & Adhesive Drip?

The 8.4-inch Uconnect touchscreen suffers physical delamination: the optically-clear adhesive (OCA) bonding the glass digitizer to the display breaks down under repeated dashboard heat cycling. This produces bubbles and cloudy patches, then 'ghost touches' where the screen regist… Repairs typically run $150-$1,200. Severity: medium.

What is the 2018-2025 Jeep Wrangler 2.0L Turbo Coolant Leak from Y-Fitting, Reservoir & Coolant Inlet Tube Fasteners?

The 2.0L turbocharged four-cylinder (GME-T4) is prone to recurring low-coolant warnings and external coolant leaks. Heat radiating off the turbocharger embrittles the plastic coolant 'Y' fitting and the coolant overflow/recovery reservoir, causing them to crack and weep. Separate… Repairs typically run $120-$600. Severity: medium.

The 3.6L Pentastar's combined oil cooler and oil filter housing adapter sits in the engine valley and is made of plastic that hardens, warps, and cracks under sustained underhood heat — it can also crack from over-tightening the oil filter cap. The resulting oil (and sometimes co… Repairs typically run $150-$700. Severity: medium.

What is the 2007-2025 Jeep Wrangler Front Wheel Hub/Bearing Assembly Failure (Integrated ABS Sensor) — Grinding & ABS Light?

Front (and sometimes rear) sealed wheel hub/bearing assemblies are a high-wear item on JK and JL Wranglers, especially on lifted rigs running larger tires that load the bearing harder. As the bearing wears it produces a speed-dependent grinding, rumbling, or humming that changes… Repairs typically run $150-$600. Severity: medium.

What is the 2012-2021 Jeep Wrangler P0011 — Intake Cam Timing Over-Advanced from Stuck Oil Control Valve / Dirty Oil (3.6L Pentastar only)?

P0011 tells you the Bank 1 intake camshaft is stuck (or lagging) in the over-advanced position — the PCM commanded a phaser position it can't achieve. This code applies to the 3.6L Pentastar V6 (2012+ JK/JL), which uses dual VVT with a cam phaser on each of the four camshafts con… Repairs typically run $50-$500. Severity: medium.

What is the 2007-2023 Jeep Wrangler Hardtop Rear Tempered Glass Spontaneous Shattering?

Owners across JK and JL hardtops report the rear (and occasionally quarter) tempered glass spontaneously exploding into pebbles with no impact — often while parked or driving normally. Tempered glass can fail from manufacturing-induced internal stress (nickel-sulfide inclusions,… Repairs typically run $200-$800. Severity: medium.

What is the 2012-2025 Jeep Wrangler 8HP 8-Speed Automatic Harsh/Jerky Shifting and Delayed Engagement?

Wranglers equipped with the ZF-based 8-speed automatic (845RE/850RE/8HP) are widely reported to shift harshly or jerk, especially the 1-2 shift and when accelerating from a stop, plus delayed engagement when moving from Park to Drive or Reverse. Many cases are resolved by a Trans… Repairs typically run $150-$3,500. Severity: medium.

What is the 2007-2024 Jeep Wrangler Electronic Sway Bar Disconnect Failure (Rubicon) — Water Ingress & Corrosion?

Rubicon models use an electronic front sway-bar disconnect actuator (motor + gear + control electronics) so the bar can be uncoupled for off-road articulation. The actuator housing has poor sealing, and water from everyday puddles, rain, or shallow fording (well under the adverti… Repairs typically run $200-$1,800. Severity: medium.

What is the 2018-2024 Jeep Wrangler Uconnect 4/5 Touchscreen Freezing, Reboot Loops & Backup Camera Blackout?

The 8.4-inch Uconnect 4 and the newer Uconnect 5 head units frequently freeze, glitch, reboot multiple times before booting, or go to a black screen. A common and safety-relevant failure mode is the rear backup camera failing to display when shifted into Reverse, showing a blue/b… Repairs typically run $0-$1,200. Severity: medium.

What is the 2018-2023 Jeep Wrangler Windshield cracks/chips far too easily (thin, fragile glass)?

JL Wranglers (and Gladiators) are widely reported to have windshields that crack, chip and fracture from minor road debris impacts that would not damage a typical windshield — sometimes within days or a few miles of delivery. The near-vertical windshield and apparently thin glass… Repairs typically run $250-$1,000. Severity: medium.

What is the 2018-2023 Jeep Wrangler ESS (Engine Start-Stop) System Issues?

The automatic engine start-stop system can be problematic, with complaints about delayed restarts, aggressive shutoffs, and system deactivating in conditions where owners expect it to work. The system defaults to ON each time the vehicle starts. Repairs typically run $50-$300. Severity: low.
