 I was driving down the highway,and all of a sudden i heard a loud noise. so i pulled over to the nearest gas station and realized i was leaking oil profusely. then i realized the driver side motor mount had broken off of the engine causing a large hole in the engine block. i have taken great care of my vehicle, changed the oil every 3,000 miles, and then this happens at random. i didn't hit anything to cause the motor mount to break, so why would it break for no reason? anyways, the leaking oil caused a fire beneath my vehicle, and inside the engine compartment. but i quickly put out the fire by a container of water i had in my vehicle. i had my 13 year old brother with me and thank god he or myself was not injured. but it caused us great fear and stress. *tr

 Car stalls while driving with no warning. stalls on freeway or in city driving. this is an infamous manufacturing defect on 96 jeeps. very hazardous because engine cuts out completely while in motion. requires pulling over with engine not running to restart engine. jeep then will repeatedly die after re-starting. since engine dies while in motion, cars behind are in real danger of colliding with my vehicle. this issue is almost impossible to fix with normal mechanical problem-solving. engine light does not come on. this issue is well documented in online blogs for jeeps with this problem. this problem with stalling while in motion poses a great threat to public safety. jeep/chrysler is aware and does not acknowledge the problem.

 The entire rear axle was replaced at the advice of jeep service. they claimed that the wheel bearings would not not seat in the axle as the "races" were worn beyond the point of holding them in. because i needed the vehicle for my business, i had no choice but to have them repair it while they had it apart as i did not have time to do the job myself. it was a three week wait for parts as it was. then i noticed the "musty" smell. upon futher investigation i discovered the entire jeep was saturated under the carpets on both sides. mold everywhere. no wonder my allergies were killing me. i've since gutted the vehicle and bleached the entire floor areas. i am now in the process of coming up with a solution to the problem so i can pass it on to other jeep owners. chrysler has a bulletin out on a procedeure to clean the a/c drain but it does not work as it comes back each year. i've found that gluing nylon screening in the air intake under the hood keeps all of the debris that clogs this drain tube out of the heater box. now i am working on a way to stop the water from running back into the dash area through the firewall where it drains out into the frame. not one dealership would talk to me about this. i know that they know about it because of the bulletin. also, i found that the "vents" behind the rear fixed glass on the cherokee have a small holding cup and a tube which the water that enters that area drains into, what i couldn't believe was that it drains into the rear of the vehicle, inside, which results in the entire rear of the vehicle becoming wet under the rear rug. this problem is solved by punching a hole through the floor and extending the factoy drain tube through the floor so the water drains outside the vehicle where it belongs. i am a car buff and pretty knowledgeable about repairs and i could not believe my eyes when i saw these design flaws. they are blatantly obvious.

 The shearing of the right engine mount to engine bolts could have allowed the engine to drop down onto the steering mechanism thereby causing loss of control. due the the engine droppping down on the right side, the rear transmision mount was torn from the cross member and the transmission shifted right which could have caused a drive shaft disconnection. i don't know if the engine shift could have impacted the throttle linkage. this shearing of the 3 mounting bolts was not caused by normal wear and tear as the bolts failed simultaneously. it is possible that the bolts were not sufficiently hardened, or possibly over tightened at assembly causing premature failure. the vehicle was essentially disabled and the only thing keeping the engine in place was the distributor landing on the chasis mount hanger.

 I crossed a railroad track at approximately 15 mph and came to a stop approximately 1 block away. as soon as i applied the accelerator, a loud bang and the sound of dragging a muffer occured. i immediatley pulled over and discovered that the shroud around the primary fan was broken into many pieces. i took the jeep to the dealer the next day they were open (occured on a saturday) and was told that the 3 bolts securing the right engine mount to the block had sheared causing the engine to fall several inches. this requires removing the engine to drill and tap the three holes to install a new bolts. diamler-chrylser is willing to pay for the bolts but not the $1000 labor. the jeep has never been off road and maintained excellently.

 On the first occasion the motor mount bolts broke and the side of the engine collapsed downward. due to the collapse the fan moved down and it hit the fan cover. when the motor mount collapsed it chipped away at the surface of the engine block. the second time the motor mount bolts came out completely and the engine fell to the side again this time wedging fan into the radiator. the first time the dealership repaired the motor mounts, but obviously did not do a good enough job, in order the keep the motor mount secure.

 Three engine mount bolts snapped at once while driving 55 mph on palisades parkway in new jersey. there was no warning (vibrating engine, noise, etc) before bolts snapped. according to my mechanic, this is the second jeep cherokee he has seen with this problem. since there is relatively low mileage on the jeep, and since i do not drive it off road, this should not be happening. the only reason the engine remained in the car was due to the distributar cap. it took 4 titanium drill bits to remove all three snapped bolts. were it not for my distributor cap, this problem could have cause a major accident on a major new jersey highway.
