 Car stalls when driving with no warning. have taken it to the dealership and they have not found the problem. it continues to stall no matter the weather or how long have driven the car. it does not give you a warning of the stall. the car stop while turning or just driving on the freeway (highway) at any speed. i have been very luck and not gotten killed. due to the car stalling on the freeway. and from the internet information there are alot of grand cherokees out there having the same stalling problem. hope that nobody has to die before this issue is addressed. there was a recall regarding the stall problem for the 2008 cars but it should of been done for the cars from 1996 to 2008. due to having the same stalling problems. *tr

 My 98 jgc started stalling randomly; on acceleration, deceleration, highway, stoplights, etc. it would always start back up and run again, but the stalling would happen at any time. no codes would register either. the dealer tried replacing the idle air control motor and ignition coil ($300), but the problem continued. i replaced the ignition wires, distributor cap, spark plugs, and throttle position sensor but still the same. . when this occurs the electrical system would drop out momentarily. also, when the asd drops out, there are no computer codes registered. they also cleaned the contacts on all the relays under the hood and coating with di-electric grease. this did not help either. *tr

 Yesterday, april 8th 2009, i drove to class and there were no problems or signs of them. after 1 hour, i started the car, which started fine, and began to drive back home. at a stop light 2 minutes after leaving, i press the gas, and the car seemed to stall, as if the engine was giving way or stumbling. this happened about 4 times, getting very close to stalling. the following day, today, april 9th, after leaving the car off for the night,it started perfectly. 2 minutes later, at a stop light, it lost all power. it had trouble turning over the first two attempts, but the third time it started perfectly. after that, i began driving again and in the middle of the road while driving, again the car lost all power. i was in the middle of traffic and put the car into neutral, tried to start it again. the first couple attempts the engine didn't turn over, but again, when it did start, it started perfectly. this happened a couple more times. after leaving again, it was about 20 minutes after ignition that when on a main road, it did not stall completely, but was like it was starting/trying to. it stumbled and jerked roughly. after that, it drove rough, before i returned home and turned it off. i am afraid that if i am on a highway or main road, this will happen again at a higher speed, causing an accident/harm to me/drivers around me. i have searched everywhere for any information on how to fix this, and many other jeep owner have the same problem, and have spent thousands of dollars and been told by numerous mechanics they can not find the problem. *tr

ENGINE AND ENGINE COOLING - COOLING SYSTEM
12/05/1998104/01/1998
 I am a friend who will describe the problems that celena has encountered with her grand cherokee laredo. the first, she noticed a spraying of oily fluid near the top of the radiator more towards the area near the battery. at that point, she noticed that the interior portion of the hood had some dark oily spot. i has suspicion that it had originated from a leaking 3/8 -1/2 fitting attached to the side of the radiator and leading towards the bottom of the transmission. she brought it in the dealership for an inspection. master mechanic inspected the suspected area. due to the fact that the transmission fluid line connects to the radiator to allow the oil to cool or something like that. anyways, they went ahead and placed teflon tape at the area. problem #2, i notice some oil on the front driver side floor mat. the location of the spill had occurred underneath, to the left, of the steering wheel column or underneath where they would place the connector to perform the computer diagnostic . the area would be where the left foot would normal rest on the mat. the area of the spill was about 8 in length and 3 in width. the viscosity would be of a dirty brake fluid oil, hydraulic, or power steering fluid. the amount would be about 1 - 1 1/2 tablespoon full. i am concerned that it could be damaging something if the oil vacated a reservoir/fluid line or the risk that the brakes can fail if it is brake fluid. problem #3 - right rear passenger window intermittently does not move up or down when it is opened or closed. thxs in advance...please help.

 1. fuel injector failed causing the engine to misfire and operate on only 5 out of 6 cylinders. 2. in the same cylinder (#6) rod broke, causing engine to blow and need replacement at only 42,000 miles. 3. power steering pump almost fell off the vehicle. (most likely due to improper installation after engine rebuild). 4. brakes constantly squeak or make grinding noise when pressure is applied. when temperatures are below 50 degrees, a high pitched whinning noise is heard from underneath the vehicle. can only be heard when traveling under 45 mph - due to road noise masking the sound. (multiple dealers have not been able to determine what the problem is nor be able to fix it, so constantly whines). 5. fuel gauge fluctuates when 3/4 full (drops to empty and fuel light turns on, then returns to normal reading. will continue to do this until tank is 1/4 full). told this is a problem with the fuel sensor. 6. transmission is occasionally rough (jerky shifting between 1st and 2nd gears).*jb

 I was driving north on rt. 684 with my gas gauge reading was 1/4 full. vehicle stalled in the third lane of the highway. i managed to pull over and avoid oncoming traffic. one hour later, a state trooper picked me up and drove me to a service station. he told me that my vehicle may have a faulty gas guage as he has picked up other drivers of jeep grand cherokees that have had the same thing happen to them. he said he thought that certain years of the vehicle had been recalled. he turned out to be right. once the vehicle was refueled, i had no problems starting up and driving home. the next week i took the jeep into pamby motors in ridgefield ct and they replaced under warranty the defective part. i was fortunate that the incident occurred when i was alone and not with my family or at a time when the traffic volume would have made it more difficult to avoid traffic. i would like to hear back from chrysler and the nhtsa about this problem, whether it is widespread and what chrysler intends to do about it. *ak

 All of the problems identified in my complaints are covered by chrysler extended warranty. but i strongly feel jeep is building an inferior and unsafe product which can cause serious accidents. the most notables were the (2) auto transmissions failure at freeway speed. the transmissions had to be replaced and the replacement unit was installed with a defective pump which also went out. the most recent incident is with the engine and all electrical system shuts off at freeway speed with no warning. the explaination given was a weak battery and loose battery cable. all other incidents are due to sub-standard jeep oem parts. i wish my complaint will force jeep to investigate why a jeep grand cherokee 5.9 limited, their flagship, would failed time after time at such a young mileage. thank you.*ak

 I own a 1998 jeep grand cherokee limited 5.9 liter engine. i drive the car 5000 miles/year and the car has 39000 total miles. the catalytic converter failed and began to rattle. the local jeep dealership refused to admit it was the catalytic converter , and said it was the muffler. i took the vehicle to 4 different exhaust shops, and all 4 immediately said it was definitely the catalytic converter. i finally got the jeep dealership to replace it and they too finally admitted it was indeed the catalytic converter. while i have been dealing with this issue i did much research on this cars catalytic converter. i found many websites with owners of my same car and other similar chrysler cars that use the same catalytic converter. every owner that wrote complaints described exactly what my problem has been. they all said that their catalytic converter has broken from between 8000 miles, the average seemed to be 44000 miles, and had to be replaced on average 3 times before 100000 miles. there is obviously a problem with this epa required exhaust part that the manufacturer has been using. please look into this issue.*ak

 Exhaust manifold has cracked. local dealer says this is common and will replace with after market manifold. they use after market because factory manifold has a design flaw.*ak

 Dealer identified a cracked exhaust manifold in my 1998 jeep grand cherokee. the car only has 49,600 miles and is not used for off-road driving. i believe there is a manufacturer defect. most owners, as in my case, find out too late. there seems to be increasing and recurring incidents with the 4.0l engines. chrysler redesigned the 1999 models without notifying 1998 owners of the manifold problem. chrysler is not willing to pay for any of the $1200 plus it will cost me to repair. *ak

 Broken exhaust manifold, allowing exhaust gases to exit exhaust system. allowing gases to enter passenger compartment possibly causing death from carbon monoxide poisoning. this is the second time that i had to replace this manifold. at a cost of $1127.00 each time.

 Exhaust manifold is cracked,causing fumes/odor to escape out into engine compartment, and can be smelled in passenger's compartment. *ak the consumer believes the exhaust manifold was defective but the manufacturer declined to replace. *yh
