What to look out for
Serious issue
Ask the seller for the service history and look for a dealer invoice or service stamp showing recall PRA 2018/16849 (campaign U63) was done.
Cruise control cannot be cancelled recall (KL Cherokee, 2014-2018)
KL Cherokees from 2014 to 2018, with any engine, were recalled (PRA 2018/16849, campaign U63) because an engine control software fault could stop the cruise control cancelling, so the car could keep accelerating until the driver braked hard or shifted to neutral. The fix is a free software update at a Jeep dealer.
What you would notice
Serious issue
Cold-start the engine immediately and listen for rhythmic tapping from the top of the engine.
2.4L MultiAir Hydraulic Lifter Collapse
The 2.4L Tigershark MultiAir system actuates intake valve lift electronically using individual oil-pressure-fed hydraulic tappets governed by solenoid valves inside the camshaft carrier. Varnish and sludge from infrequent oil changes block the 0.5 mm oil galleries supplying each tappet, collapsing the hydraulic element to its minimum-lift position. The affected cylinder misfires persistently, and mechanical contact between the collapsed lifter and camshaft lobe accelerates wear on both components. Severe cases require full camshaft and carrier replacement in addition to tappet replacement.
What you would notice
Costly issue
Drive the vehicle from cold through stop-start traffic and note any hesitation or clunk when accelerating from rest.
ZF 9HP (948TE) nine-speed harsh shifts and low-speed hesitation (KL Cherokee, all engines)
The ZF 9HP45 nine-speed automatic fitted to the KL Cherokee was introduced before adequate calibration was finalised. The transmission control module software struggled to select appropriate ratios at low speeds because the closely stacked lower gears (1st through 3rd) require very precise torque converter lockup management. The result is harsh or lurching 1-2 upshifts, unpredictable kickdown, and hesitation when pulling away from rest. Multiple TCM software updates were released by FCA, but many vehicles received only partial reflashes. On higher-mileage examples, progressive solenoid wear inside the valve body causes inconsistent clutch pack fill pressures that compound the calibration-related problems.
What you would notice
Costly issue
Get proof of when the timing belt was last done — if it's unknown or overdue, budget to do it immediately.
2.8 CRD (VM Motori) turbo, EGR and timing-belt vulnerabilities (KJ/KK)
The 2.8 CRD diesel (VM Motori) used in the KJ and KK Cherokee/Liberty is a strong workhorse when maintained but sensitive when neglected. Known weak points are variable-geometry turbo wear/sticking, EGR and (where fitted) DPF clogging, and a timing belt that must be replaced on schedule — a belt failure destroys the engine. Neglected examples also see rocker/lifter wear and, in extreme cases, crankshaft problems. Servicing history is everything on this engine.
What you would notice
Costly issue
Check oil level on dipstick — low level on a recently serviced vehicle is a red flag.
2.4 Tigershark Excessive Oil Consumption
The 2.4L Tigershark four-cylinder engine in the KL Cherokee is documented to consume engine oil above normal limits, with many owners reporting up to 1 litre per 1,200–2,000 km. The consumption is attributed to piston ring design and valve stem seal wear. Chrysler acknowledged the issue and revised the acceptable consumption threshold rather than engineering a full fix. Consistent oil top-up is required to avoid low-oil-level damage. Engines run low on oil by unsuspecting owners can suffer bearing and timing chain damage.
What you would notice
Costly issue
On a quiet drive listen for a speed-related whine or growl, especially at lower speeds, and feel for any banging/jolt.
Power Transfer Unit (PTU) failure on AWD models (KL)
AWD KL Cherokees are prone to Power Transfer Unit (PTU) failure — the unit that sends drive to the rear. A common failure mode is the internal actuator motor frying when gear oil seeps into it. It typically starts as a whine or growl that changes with speed (worst under about 50 km/h) and can progress to banging/jolting or loss of drive; recalls exist for PTU-related power-loss/rollaway risk. It's a frequently reported, not-cheap repair on this generation.

Can't confirm for this car
The 3.2 Pentastar V6 in KL Cherokees shares the roller rocker design of the 3.6, and the needle bearings in the rocker rollers can break up. The roller then drops out of place so the rocker scrapes on the camshaft lobe instead of rolling, giving a rhythmic ticking from the top of the engine. If ignored the cam lobes wear away and metal particles circulate in the oil, which can damage bearings and end with a camshaft or even engine replacement. Caught early it is a rocker and lash adjuster job on the affected head.

01Power liftgate module water ingress, short circuit and fire risk (recall 49A)
Can't confirm for this car
Can't confirm for this car
On early KL Cherokees with a power tailgate, water can get into the power liftgate module, corrode it and cause a short circuit that may start a fire whether the ignition is on or off. FCA made the module more resistant to water from September 2015 and recalled earlier cars under campaign 49A (US 23V-338, about 132,000 vehicles; Australia REC-005956, 10,158 KL Cherokees). The fix relocates the module, adds a water shield and replaces the module and connectors if corrosion is found. Until it is done the advice was to park outside and away from buildings, so an unrecalled car is a real risk.

03TIPM (integrated power module) electrical faults (KK Liberty)
Can't confirm for this car
Can't confirm for this car
The KK Cherokee/Liberty (like other Chrysler/Jeep vehicles of the era) can suffer TIPM (Totally Integrated Power Module) faults — the under-bonnet computer/fuse box. When it plays up it causes odd electrical behaviour (no-start, phantom electrical gremlins) and, because the relays are soldered to the board, it's not a simple fuse swap. It's not universal on the KK but when it fails it can be an expensive, hard-to-diagnose fault.

04Power window regulator failure (KJ Liberty)

Can't confirm for this car
The KJ-generation Cherokee/Liberty is notorious for power-window regulator failure — the window can drop into the door, sometimes at speed. It's a widespread, well-documented fault on this generation (the later KK largely fixed it). Not dangerous but inconvenient and, with a window stuck down, a security and weather problem. Parts are cheap; it's the recurring nature that annoys owners.

01Front lower ball joint wear (KJ/KK Liberty)
Can't confirm for this car
Can't confirm for this car
Front lower ball joints are a well-known weak point across the KJ and KK Cherokee/Liberty — they wear and get damaged relatively easily, causing knocking noises and, if left, a safety hazard from excess play. It's one of the most frequently reported suspension items on these SUVs and a WOF concern. Replacement is straightforward but a worn joint should be fixed before driving hard.
Example of the part — not this vehicleA separated lower ball joint: the control arm has dropped and the wheel has splayed out under the guard.

Early KL Cherokees, with any engine, were recalled (PRA 2015/14575) because the airbag control software could read steep off-road angles as a crash and fire the airbags with no impact, distracting the driver and blocking the view. The fix is a free airbag control module software update at a Jeep dealer.

Like any used car, it depends on the specific example and its service history. Across the 18 documented faults for the Jeep Cherokee, the recurring problem areas are transmission, engine, and electrical. A Jeep Cherokee with a full service history and no signs of the issues listed on this page can be a sound buy but each one needs to be checked individually before you commit.
What are the most common problems with a used Jeep Cherokee?
We've catalogued 18 known faults for the Jeep Cherokee, covering transmission, engine, and electrical. All 18 are written out in full on this page, with the symptoms to notice, what to inspect, and typical repair costs for each. Free to read, no account needed.
How much do repairs cost on a Jeep Cherokee?
Most single repairs on the Jeep Cherokee fall between $400–$3,500 at NZ independent-workshop rates. Some of the 18 documented faults cost less and a few cost considerably more, and no one car needs them all. Knowing which ones to look for before you view is what lets you negotiate the price down or walk away.
Should I get a pre-purchase inspection on a Jeep Cherokee?
Yes. A Jeep Cherokee inspection focused on its known weak points is the single best way to avoid an expensive mistake. KickTyres gives you a guided, model-specific inspection plus a market valuation and negotiation figure for $24.90 far less than the cost of missing one of the faults on this page.
