Two problems related to engine failure have been reported for the 2000 Jeep Cherokee. The most recently reported issues are listed below. Please also check out the statistics and reliability analysis of the 2000 Jeep Cherokee based on all problems reported for the 2000 Cherokee.
My vehicle has been losing coolant for quite some time. It has relatively low mileage to have head problems, but I now have coolant in my oil. I have done some research and found that daimler-Chrysler used 0331 cast heads on this model Cherokee (2000 w/ 4. 0l engine). It turns out that these heads were a poor cast allowing cracks to form near the #3 cylinder area allowing coolant to flow into the oil. This results in a drop in oil pressure and eventually bearing and engine failure. I consider myself somewhat lucky that I discovered this problem before the engine seized up on me, however I am now looking at over $1000 in repairs that should not be necessary for a vehicle with just over 50k miles. I am very disappointed since I believed Jeeps to be reliably built vehicles. I sincerely hope that someone from daimler-Chrysler will read this and rectify the situation before the engine failure leads to an accident or death.
Cylinder head cracked at only 70,000 miles allowing coolant into the oil sump, potentially leading to engine failure or, as dealer stated, "engine may seize completely .
