Jeep Liberty 2002–2007

1st generation (KJ) · KJ · 9,715 complaints, 6,239 with mileage

Owners filed 9,715 complaints with NHTSA about the 2002–2007 Jeep Liberty, and 6,239 of them record the mileage at which the failure happened. That is enough to show not just what fails, but when.

Failures are spread across the mileage range, with the middle half between 39,000 and 110,000 miles. The median is 70,000 miles.

The most-reported areas are the suspension (20.7% of complaints, typically around 68,000 miles), the airbag system (11.1% of complaints, typically around 109,500 miles), visibility equipment (10.1% of complaints, typically around 49,400 miles).

Which systems, and when

Complaints about this generation are not spread evenly across the vehicle, and the systems that generate the most of them do not all fail at the same point in a car's life. The median failure across all systems here is 70,000 miles; the figures below show which parts of the car run ahead of that and which run behind.

The suspension accounts for 20.7% of complaints (2,015 reports, 1,405 of them with a mileage figure), with a median of 68,000 miles, close to the vehicle's overall pattern. The middle half of these reports falls between 40,000 and 110,000 miles.

The airbag system accounts for 11.1% of complaints (1,077 reports, 574 of them with a mileage figure), and it fails late — a median of 109,500 miles, considerably beyond the vehicle's overall median. That pattern is consistent with normal service life rather than a defect, though it matters for anyone buying an example already near that mileage. The middle half of these reports falls between 70,000 and 150,000 miles.

Visibility equipment accounts for 10.1% of complaints (978 reports, 840 of them with a mileage figure), with a median of 49,400 miles, close to the vehicle's overall pattern. The middle half of these reports falls between 32,000 and 70,000 miles.

The fuel system accounts for 7.7% of complaints (746 reports, 274 of them with a mileage figure), with a median of 60,000 miles, close to the vehicle's overall pattern. The middle half of these reports falls between 40,000 and 90,000 miles.

Body structure accounts for 7.5% of complaints (729 reports, 198 of them with a mileage figure), with a median of 93,500 miles, close to the vehicle's overall pattern. The middle half of these reports falls between 63,000 and 126,712 miles.

The fuel and propulsion system accounts for 7.4% of complaints (721 reports, 266 of them with a mileage figure), with a median of 90,000 miles, close to the vehicle's overall pattern. The middle half of these reports falls between 60,000 and 125,000 miles.

Differences between model years

Within this generation, complaint volume is not constant across model years. The 2002 model year drew the most — 2,330 complaints — while 2007 drew the fewest at 941. The median year sits at 1,596.

Recalls and what they cover

NHTSA records 7 recall campaigns covering vehicles in this generation. A recall means the manufacturer or the regulator concluded there was a safety defect or a standard was not met, and that a free remedy is owed to owners — including second and later owners.

The campaigns cluster around the airbag system (3), the suspension (2), the transmission and driveline (1). Repeated recalls against the same area of the car generally mean the first remedy did not fully resolve the underlying problem.

Recall status is specific to the individual vehicle, not the model. Checking a VIN against NHTSA's lookup is free and takes under a minute, and it is the only way to know whether a particular car has had the work done.

Reported severity

Of the 9,715 complaints filed against this generation, 718 reported a crash; 170 reported a fire; 715 reported an injury; 24 reported a fatality. Crash-involved reports represent 7.4% of the total.

These are owner-reported outcomes, not verified investigations, and they are not adjusted for how many of these vehicles are on the road. They are included because the distinction between a fault that strands a car and a fault that causes a collision is the one that matters most, and it is not visible in a complaint count alone.

What this means if you are buying one

For a buyer, failures on this generation are spread rather than concentrated: the middle half falls between 39,000 and 110,000 miles, with a median of 70,000. There is no single mileage threshold to watch, which means condition and maintenance records are more informative than the odometer.

On inspection, the suspension and the airbag system are where this generation's reports concentrate, so those are the areas worth a specific look. The suspension in particular shows a median failure mileage of 68,000, which gives a concrete number to compare against the odometer of any car you are considering.

None of this is a substitute for a pre-purchase inspection on the individual car. Aggregate patterns describe a population; the example in front of you has its own history.

Documented problems

Suspension/steering 2002-2003

Front lower control arm ball joint wear and separation. NHTSA recalls covered vehicles built 2 Jan 2001 - 4 Oct 2002 (modified ball joint assemblies plus heat shields) and 5 Oct 2002 - 26 Mar 2003 (inspect/replace as necessary with heat shields). Heat from the exhaust degrading the joint boot was implicated.

Body/electrical 2002-2007

Window regulator failure — the regulator binds, tips the glass forward, chatters, and the window drops into the door, often suddenly. Subject of a US class action alleging the defect spans the whole generation and cannot be permanently repaired.
