 Many problems with this vehicle. water pump leaked - fixed under warranty, gas tank seal leaked - fixed under warranty, seats ripped - fixed under warranty, suction cup marks on window - fixed under warranty, front stabilizer shock leaked - fixed under warranty, rear window seal leaked - repaired under warranty two times and still leaks, instrument panel fails - out of warranty not repaired, radiator failed - out of warranty fixed at my cost, stabilizer arm failed both sides twice - fixed under warranty once and the out of warranty fixed at my cost, exhaust manifold failed - out of warranty - fixed at my cost, clutch fork failed - out of warranty fixed at my cost, leak under the dash board passenger side - fixed under warranty. of all the problems above... loss of instrument panel needs to be fixed by the manufacturer regardless of in or out of warranty. loss of gauges is a driving distraction and can result in an accident. jeep needs to address this manufacturing defect as long as this vehicle is on the road. *jb

 1998 jeep wrangler, 4.0l. these two issues are on service bulletins, but should be recalls. the first issue occurred as my wife was driving when the valve springs snapped, stopping the car in the middle of the interstate. discussed in detail on service bulletin 182298, initially issued before i even purchased my car. it was very frustrating to find out that jeep was aware of such a dangerous issue and did nothing to prevent such failures from occurring. the second is a very widespread and documented problem when the main instrument cluster spontaneously stops working, including the speedometer, odometer, air bag indicator, fuel gage, oil gage, etc... discussed on service bulletins, 081599 i believe. you cannot tell your speed, how much gas you have, etc... another implication is that the odometer is incorrect on many jeeps. *la

 Exhaust manifold bolts are snapping off in the block of jeep 2.5 4 cyl engine. this problem is documented by chrysler as a design fault problem but they will not cover it. the problem has not been repaired yet because chrysler will not cover it and it is a very expensive fix that can't be afforded at this time. the problem is also a safety problem due to the fact that the exhaust is leaking from between the manifold and head and could get into the vehicle. the problem was first noticed in about jan 02. the vehicle currently has 54000 miles on it. this vehicle also had a total catalytic converter failure that was covered under the emissions warranty. i feel that this problem with the exhaust manifold should be covered under, the same warranty, especially considering the fact that it was a faulty part design and not wear an tear. catalytic converter "imploded" all the interior components came loose and began to rattle. it was replaced under the 8 year 80,000 emissions warranty. supposedly a common problem

 The mannifold has cracked twice. the first time, jeep fixed it, stating there was a design flaw. now, approx. two years later, and another 32,000 miles(roughly) the same thing happened again. this time, they would not fix it, due to mileage. however, i feel as if there is a design flaw, and this happens every 30,000 miles or so, someone should be aware of the problem and attempt to correct it. i just had it fixed for the second time and the cost was $600.00. nlm

 I took the jeep last year to get the rattle fixed. they fixed it, but on the 1/12/02 i took it back for the same rattle. i don't believe they fixed it, just tightened the linkage up. my wife and i spent 7 hours at landers without anyone contacting us about what the problem was. they also broke a bolt off in the block that holds the exhaust manifold on, again we weren't informed. our warrenty covered the exhaust problem, but landers said that the linkage wasn't covered even though they had worked on the linkage less than a year ago. they are supposed to cover any repairs they make for a year, but they didn't honor this. we spent 7 hours waiting for the jeep to be repaired. they offered us a rental to get us home, but didn't offer any gas money or anything for our incovience about driving 150 miles (one way). i'm a gunsmith and make $30 a hour and i was away from my work for 20 hours because of landers not informing me of how long the repairs would take. now i'm behind with my work and having to work16 hours a day to catch up. i would like some comp. for my time lost. also my wife went with me to landers and sat through their lies, and she lost work time also. landers is supposed to have a five star rating toward their customers. we were treated like unwanted step-children. landers didn't offer to supply us with transport to go get something to eat, inform us of the problems with our jeep, and charged us 69.97 for labor and 24.97 for parts, that shouldn't have worn out after 27,100 miles unless they damaged when they 'fixed' the linkages the first time. i know i'm not improtant to them, but i believe they destroyed the bushings the first time they worked on them, and broke the manifold bolt trying to tighten it down causing them to have to pull the head off the motor head off the engine to get to.*ak

 As i have read mentioned by others at this website, about a year after i bought the jeep, my dash gauges would go down to zero and the airbag light would go on. this problem is a winter and wet-whether related problem. if i pound on the dashboard with my fist, sometimes the gauges will recover temporarily. if they do recover, they almost immediately go back down to zero. i spoke with a dealership about the problem. they acted surprised. i see from other peoples comments that their are numerous other occasions of this problem. i thought i was alone with this problem until earlier today when a mechanic friend of a friend mentioned someone else with the 1998 jeep wrangler has the exact same problem. i need a response from the government. has there been a recall issued on this? i have also had my catalytic converter crumble to pieces according to a local garage. he seemd to think that there was a recall on the catalytic converters. i am at a loss as to how to find out if there indeed has been a recall. please contact me.*ak

 The exhaust manifold/header cracks at the bottom on the inside pipe i have talked to a few other people and it is apperantly a very common problem on 1997 - 2000 models. it is an emmissions leak and also a possible corbon monoxside problem. i know of 8 jeeps with the same problem and i haven't talked to very many people. the replacement part is the same part that is now installed on my jeep, so i don't expect it to last very long.

 I have a 98 tj jeep 2.5lt with on it 57,000 now. what i experienced was a major power loss in the while getting on the freeway. the symptoms were as follows. the engine would rev up but the rpms & speed would rise slowly. i though maybe the clutch was slipping and pulled off the freeway and drove it back home . i noticed it got worse and the engine was running poorly at idle and if you gave it gas it would bog down and die. i also noticed strong exhaust fumes and very little pressure from the exhaust pipe. so i took it to the muffler shop for a new catalytic converter and they informed me that i should take it to the jeep dealer. because in ca there's a federal recall law that states that the dealer must replace the catalytic converter at no cost to the owner if it fails before 80,000 miles regardless if you bought it new or not and mine had 56,000. so i took it to the dealer and they installed a brand new catalytic converter free of charge and labor. the jeeps runs great and the dealership was very nice .they said they have had problems on this with certain models. hope this helps. oh if you really want to know if that's the problem just disconnect the exhaust pipe going up to the exhaust manifold real quick and fire it up if it starts right up and has power then you know that's it. but hook it back up don't drive it like that. you might damage the engine. you'll need a 14mm deep socket and some wd40 to removed the 2 nuts on the studs. that's it. *nm

 I have had numerous problems with my jeep wrangler 1998. this is a partial list i sent to chrysler: i bought my jeep with just 3600 miles on it from a dealer in 1999. from day one i started experiencing problems. many of them i returned to the service department. some they were able to fix, others, after many return trips, they were 'unable to duplicate the problem'. 1. gauges would stop working while driving - i brought the vehicle in 5 times before they were able to duplicate and finally fix the problem. 2. this was also true of the blinkers that not always worked - or worked all at the same time. 3. my hazards still do not work every time. 4. the air conditioner goes out when driving,very uncomfortable when it is hot and raining. 5. the sound bar has never worked properly - first it would only come in some times - now never. 6. headers are cracked - bad. they have been welded several times. when i went to have them welded it was found they were welded before my purchase - at 3600 mil! they are still cracked, welding does not hold. i can not get anyone to replace them because even exhaust specialists say it is too cumbersome. the dealer charges way more than i have considering the number of repairs and the price of gas - at 12 mpg. 7. drivers seat belt locks tightly with any amount of pressure on the brakes - it has now gotten to the point it locks just while driving. 8. windows - the zippers broke almost immediately - i paid alot to have these replaced. the back window now has a cut in it and is very difficult to see through. 9. the top has never quite fit right; it has always leaked and been extremely noisy - more so than anyone else's that i know. it has also come apart at the seams. the dealership has not been of any help. they wanted to charge outrageous amounts just for diagnostics, even when i had the best warranty. i've also had problems with the door molding coming out immediately, grinding in the steering wheel, grinding while trying to put it in reverse and more. *nlm
