2001 Jeep Cherokee engine problems

Filed Sep 14, 2017 · Engine · 117,000 miles · NY

As with many other jeep owners with the 4.0 engine (hundreds that I have seen) my 2001 jeep cherokee's cylinder head cracked. Mine was at 117k miles, and the average mileage for failure seems to be 100k - 120k miles. This is a definite design flaw. My jeep was well maintained and should not have had a cracked cylinder head. I ask the federal safety agency to contact current owners of jeep 4.0 engines to really see how often this fault occurs. Chrysler seems to take no responsibility for this, which is why I am asking the federal safety agency to investigate.

In the 2000 and 2001 cherokees with the 4.0 engine head casting 0331 chrysler knew about the cylinder heads cracking. In 2002 they contracted with tupy manufacturing in brazil to remake the head casting that ran until the 4.0 was stopped being used by them. Mine has since cracked and chrysler says that no factory recall was done and such I'm stuck with a cracked head that they knew was faulty.

Tl* the contact owns a 2001 jeep cherokee. When the vehicle was powered off and restarted within five minutes or longer, the vehicle would hesitate to start or have a rough start and the check engine warning light illuminated. The vehicle was taken to an independent mechanic where it was diagnosed that the third cylinder failed. The vehicle was not included in the federal safety agency campaign number: 02v104000 (fuel system, gasoline). The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was 155,000.

Slowly loosing antifreeze, antifreeze mixed with oil. Found to be cracked head, apparently a common issue with this vehicle. Replaced head. A few months after replacement of head, started to loose antifreeze again replaced head again in nov 2014. Had vehicle back for one week, lost all antifreeze, mixed with oil again. Have been told that 2000 and 2001 jeep cherokees and grand cherokees have a very high rate of this happening. There should be a recall.

After loosing coolant at about a 1/2 per week, finally decided to pull the head and check to see if it has the famous jeep 4.0l, 0331 head casting and is known to be weak. Yep, I have the bad head with cracks. There should be a recall for this as it has a high failure rate.....

Car will not start on the first try, and when I did get it running the check engine light was on. Took it to a mechanic when we started the car the engine light was out and when he put the tester on it pulled no codes and no monitors. Said they had all been erased. I have had the car stall on my when sitting still, the chime works intermittently when you put the key in the ignition, the head lights will sometime stay on and sometimes turn off rightaway when you shut the car off.

Head liner has fallen and now it is breaking apart and particles are flying all over the inside of my jeep and I am on oxygen and need to open my windows because the air only works some times and when I use it the car temp get very high and the engine light comes on I have had the radiator flushed twice even replaced the radiator at one point also changed the thermostat I love my jeep but I hate to say it if I have to replace it I doubt if I will buy jeep or dodge again.

Started noticing loss of oil pressure and then coolant. The engine continues to run fine but has gotten to the point that its losing 1 gallon of anti. Every two weeks or so. When I started to look around on line and other places, (junk yards) everyone I talked to says they have had the same problem with their jeeps. Why if d.c. Produced these faulty heads on their jeeps didn't they recall them to fix?

My daughter called because of a noise in the engine compartment. I went to her work, raised the hood, started the engine, and shortly 1-2 minutes thereafter, a loud popping/grinding occurred. The fan disintegrated sending parts through the radiator, shroud, and toes of my left shoe. And injury could have occurred but did not. I found 1999-2004 jeeps had a recall for this very type of event. However, it missed he VIN. I believe all of these vehicles should be included in the recall. My youngest son has a 1999 that the fan came apart damaging the radiator and resulting in engine failure. I have owner 7 jeeps but never seen this before. Any assistance in alerting the public will be appreciated.

1. Vehicle was losing coolant but nothing showing up in the engine oil coolant or burning out the tail pipe. I was going through about a half gallon per week. Vehicle maintained loss of coolant for about 6 months, the added problem of lost oil pressure then became a problem. 2.eventually the head started leaking bad enough that coolant was present in the oil, at which point the problem was present and able to diagnose. 3. At that point the main bearings were a complete loss and determined that the cam bearings were gone as well and had to replace the entire motor.
