NHTSA campaign 23V116000 covers certain 2018-2023 Jeep Wrangler vehicles equipped with manual transmissions. The clutch intermediate pressure plate may overheat and fracture, potentially cracking the transmission case and expelling heated debris. The debris may contact an ignitio… Severity: high.
eTorque (mild-hybrid) Wranglers replace the conventional alternator/starter with a 48V belt-driven motor-generator (BSG/MGU) plus a 48V power pack unit (PPU) and a 12V system. Owners report charging-system failures, battery warning lights, rough/failed auto-starts during stop-sta… Repairs typically run $0-$3,000. Severity: high.
Wranglers (JK and JL) with a solid front axle are prone to 'death wobble' — a violent, self-reinforcing side-to-side oscillation of the front-end steering components and steering wheel, typically triggered by hitting a bump, expansion joint or pothole at speeds above ~45-55 mph. Repairs typically run $150-$1,200. Severity: high.
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.
The 3.6L Pentastar V6 used in JK (2012-2018) and JL (2018+) Wranglers suffers a documented valvetrain failure separate from the engine's oil-consumption problem. The needle roller bearings inside the rocker arms wear prematurely, loosen, and can drop out, shifting the rocker arm… Repairs typically run $1,300-$4,000. Severity: high.
The JL Wrangler with manual transmission can experience clutch issues including premature wear, judder, and difficulty engaging gears. Some owners report clutch failures at relatively low mileage, particularly with off-road or aggressive driving. Repairs typically run $800-$2,500. Severity: medium.
Stellantis bulletin 31-002-22 applies to 2018-current JL Jeep Wrangler aluminum panels with corrosion or paint bubbling on hoods, hinges, doors, fenders, swing gates or other exterior surfaces. The bulletin warns that ferrous-metal cross-contamination during preparation can lead… Severity: medium.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
The hardtop can leak water into the cabin, particularly around the freedom panels, rear window seals, or the seal where the top meets the body. Water intrusion can wet carpets, seats, and cause electrical issues over time. Repairs typically run $50-$500. Severity: low.
The two removable 'Freedom Panel' roof sections over the front seats on hardtop JL Wranglers commonly leak water — most often at the front edge near the windshield header and at the center seam between the panels — allowing water to drip onto the headliner, sun visors, dash and e… Repairs typically run $0-$300. Severity: low.
