What is the 2008-2012 Jeep Liberty KK Sky Slider Canvas Roof - Water Leaks, Off-Track Binding and Cable Failure?

The full-length retractable canvas 'Sky Slider' roof, optional on the 2008-2012 KK Liberty, is the KK's signature defect. The front roof bow and its hard outer sealing lip do not maintain a seal against the header, so water tracks past the panel and into the headliner and A-pilla… Repairs typically run $400-$3,000. Severity: high.

What is the 2002-2007 Jeep Liberty Rear-Impact Fuel Tank Fire Risk - Trailer Hitch Recall Campaign (13V-252)?

Owners overwhelming… Repairs typically run $1,800-$5,500. Severity: high.

What is the 2005-2006 Jeep Liberty 2.8L CRD Diesel - EGR Valve Failure Causing Boost Spikes and Turbocharger Damage?

The KJ-only 2.8L VM Motori CRD diesel (2005-2006 North America) uses an EGR valve that also acts as a pressure relief path for the turbocharger under certain conditions. When the valve carbons up and sticks - the standard outcome given the oily EGR fume load in the intake - boost… Repairs typically run $500-$3,000. Severity: high.

What is the 2002-2012 Jeep Liberty Radiator End-Tank Cracking and Fan Clutch Failure Causing Overheating?

The Liberty's crossflow radiator uses plastic end tanks crimped to an aluminum core, and the crimp seam splits with age and heat cycling - the documented primary failure point on 2006-2012 radiators, with the same construction on earlier KJs.

What is the 2002-2012 Jeep Liberty Transfer Case / Differential Seal Leaks?

The Liberty is notorious for fluid leaks from the transfer case output shaft seal and differential pinion seal.

The front differential pinion seal i… Repairs typically run $100-$2,000. Severity: medium.

What is the 2002-2012 Jeep Liberty 3.7L V6 Exhaust Manifold Crack / Valve Cover Oil Leaks?

The cast iron exhaust manifolds develop stress cracks due to thermal cycling, with the passenger side being more commo… Repairs typically run $100-$2,500. Severity: medium.

What is the 2011-2012 Jeep Liberty KK Occupant Restraint Controller - Active Head Restraints Fail to Deploy (13V-282 / 17V-640)?

On late KK Libertys the occupant restraint control module suffers electrical over-stress of an internal resistor, which can prevent the active head restraints from deploying in a rear impact - removing the whiplash protection the seats are designed to provide. NHTSA campaign 13V-… Repairs typically run $0-$0. Severity: medium.

What is the 2003-2012 Jeep Liberty 42RLE Automatic Transmission - Solenoid Pack Failure, Delayed Engagement and Limp Mode?

The 42RLE four-speed automatic used behind the 3.7L V6 develops solenoid-pack and pressure-sensor faults that produce delayed or abandoned upshifts, harsh 2-3 shifts, slipping, and limp mode locked in second gear. The characteristic codes reported by owners are P0755 (2/4 shift s… Repairs typically run $350-$2,800. Severity: medium.

What is the 2002-2012 Jeep Liberty HVAC Blend Door Actuator Stripping and Blend Door Linkage Breakage?

Both generations strip the plastic gears in the HVAC blend door actuator and, more expensively, break the link bar that ties the main blend door to the secondary door inside the heater box. The signature is repetitive clicking from behind the dash accompanied by temperature that… Repairs typically run $120-$1,200. Severity: medium.

What is the 2002-2007 Jeep Liberty KJ Rear Axle Bearing and Differential Bearing Wear (Whine, Growl, Metal in Gear Oil)?

The KJ's rear axle wears out its wheel bearings, pinion bearing and carrier bearings, producing a whine or growl that changes with road speed and, in the wheel-bearing case, with loading in a corner. Owners inspecting the failure find silver sparkling metal in the drained gear lu… Repairs typically run $250-$1,500. Severity: medium.

What is the 2002-2012 Jeep Liberty Tail Lamp Bulb Socket and Circuit Board Overheating / Melting?

The rear lamp assemblies overheat at the bulb sockets. The incandescent brake/tail bulb dumps most of its energy as heat, and where the socket contact has oxidized the resulting resistance heat melts the plastic circuit-board carrier, fusing the bulb into the socket and burning t… Repairs typically run $30-$300. Severity: medium.

What is the 2002-2012 Jeep Liberty Power Steering High-Pressure Line O-Ring and Pump Leaks with Whine?

The high-pressure line fitting at the power steering pump leaks at its O-ring, and the pump itself develops shaft seal and reservoir leaks. Owners document the O-ring at the high-pressure hose as the single most common leak point on the Liberty, and report that aftermarket O-ring… Repairs typically run $80-$700. Severity: medium.

What is the 2002-2012 Jeep Liberty Power Window Regulator Failure?

The power window regulators fail at an extremely high rate across all Liberty model years, causing windows to fall into the door, get stuck partially open, or make clicking/grinding noises when operated. The failure rate was so widespread that a federal class action lawsuit was f… Repairs typically run $80-$400. Severity: low.
