Known Jeep Cherokee faults
Every fault below is documented specifically for this model — researched and verified before it’s published.
012.8 CRD injector copper seal leak — "black death"
CriticalCommonEngine $800–$6,000 to fix
The 2.8 CRD diesel used in the KK Cherokee is well known for leaking injector copper seals. Combustion gases escape past the seal and bake diesel and soot into a hard tar around the injector, a condition owners call black death. Caught early it is a seal and clean; left long enough the injector seizes into the cylinder head and extraction can mean removing and repairing the head, which is the difference between a modest bill and a very large one. The tar is visible from above once you know what you are looking for, which makes this one of the more checkable faults on the car.
Symptoms to notice
Ticking, chuffing or puffing from the top of the engine that beats in time with the engine
Black tarry crust visible around the base of an injector
Diesel or exhaust smell in the engine bay or entering the cabin
Rough running or harder starting when cold
What to check
Open the bonnet and, with a phone torch, look down at the top of the engine where the injectors enter the cylinder head — you are looking for a black, tarry, crusty build-up around the base of any injector. Clean metal at all four is what you want. Start the engine from cold with the bonnet up and listen for a rhythmic chuffing or ticking from the top of the engine that is louder than the general diesel clatter and beats in time with it; put your hand near (not on) the area to feel for puffs of gas. Smell for diesel or exhaust fumes in the engine bay. Ask whether injectors have ever been out and whether new copper seals were fitted. Check the service history for glow plug and injector work. If a workshop inspection is possible: have a compression or leak check done and the injectors inspected properly, as a seized injector completely changes the cost of ownership.
Where to look: Top of the engine — base of each injector where it enters the cylinder head
Ask the seller
“Have the injectors ever been removed, and were new copper seals fitted?”
“Is there any ticking or chuffing from the engine when cold?”
“Has the cylinder head ever been off?”
02Power window regulator failure (KJ Liberty)
MinorCommonElectrical $250–$600 to fix
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.
Symptoms to notice
Window falls into the door or won't go up
Grinding/clunk from the door when operating a window
Window jams part-way
What to check
Operate all four windows fully up and down several times; listen for grinding and watch for slow or jerky travel. A window that won't hold up or drops into the door confirms a failed regulator. Check whether any have already been replaced.
Where to look: Window regulator mechanism inside each door
Ask the seller
“Have any window regulators been replaced?”
“Do all four windows work smoothly?”
“Any window that drops or sticks?”
