Drivetrain parts in these models tend to deteriorate faster than expected, causing unexpected repair costs for many XJ enthusiasts. While not universally considered the worst years in the XJ lineup, these models demand careful inspection before purchase, especially examining wiring harnesses and power distribution centers for signs of degradation or previous amateur repairs.
The Troubled 2000-2001 Final Years
The 2000-2001 model years represent the most problematic period in Cherokee XJ production, earning their reputation as years to definitely avoid. These final production models contain the infamous “0331” cylinder head casting with a critical defect that causes cracks between cylinders 3 and 4. This manufacturing flaw leads to catastrophic head gasket failures, coolant leaks, and overheating issues that can permanently damage the engine. Repair costs for these head failures often exceed $1,500, making these final XJ years a risky investment even though their more modern amenities. Many XJ enthusiasts specifically warn against these models, recommending earlier years with the more reliable cylinder head designs instead.
Common Problems in Problematic XJ Years
The Jeep Cherokee XJ models from certain years exhibit exact mechanical and structural issues that can lead to expensive repairs and frustrating ownership experiences. Understanding these common problems helps you make informed decisions when shopping for a used XJ and potentially save thousands in unexpected repair costs.
Engine and Transmission Failures
Engine problems plague the 2000 and 2001 Cherokee XJ models due to the defective 0331 cylinder head casting in the 4.0-liter inline-six engine. This critical flaw causes cracking between cylinders 3 and 4, often resulting in complete engine failure that requires expensive replacement or rebuilding. The issue manifests as coolant leaking into the combustion chamber, leading to overheating, white smoke from the exhaust, and eventual head gasket failure. While the 4.0L engine generally earned a reputation for longevity, this particular casting defect represents its Achilles’ heel in these later model years.
Cooling System Weaknesses
Cooling system limitations affect many XJ models regardless of year, creating potential overheating scenarios in exact driving conditions. The stock cooling system functions poorly during low-speed, high-temperature situations because both the engine cooling fan and water pump operate based on engine RPM. This design flaw means crawling uphill or handling stop-and-go traffic can cause dangerous temperature spikes as cooling capacity diminishes at lower engine speeds. Aftermarket modifications like transmission or power steering coolers mounted in front of the radiator further reduce airflow to the main radiator. Running the air conditioning compounds these issues by preheating air entering the cooling system, creating a perfect storm for overheating during demanding off-road adventures or summer traffic jams.
Rust and Structural Concerns
Rust represents a serious threat to XJ longevity, particularly in later models with their unibody construction. Critical rust-prone areas include rocker panels and rear quarter panels located behind the rear wheels, where moisture and road salt accumulate. Pinch welds at the door bottoms frequently develop corrosion, especially in 1997-2001 models. Windshield edges often rust where small rock chips create entry points for moisture, eventually developing into larger holes that allow water intrusion. Floor pans suffer when leaks from the windshield or heater core go unaddressed, creating ideal conditions for rust formation. Since the XJ utilizes unibody construction rather than a traditional body-on-frame design, structural rust compromises the vehicle’s integrity and safety. Thorough inspection of these areas proves essential when evaluating any used Cherokee XJ, as extensive rust repair costs can quickly exceed the vehicle’s value.
How to Identify a Reliable XJ Cherokee
Reliable Jeep Cherokee XJ models typically fall within exact production years that have proven their durability and performance over time. Identifying a trustworthy XJ involves examining both the model year and several key condition indicators that signal a well-maintained vehicle.
Best XJ Model Years to Consider
