1994 Jeep Wrangler Problems

What owners report

Owners of this model year most often write about fuel: a gasoline smell or visible leak at the top of the plastic fuel tank around the sending unit, sometimes with gas spilling out during fill-ups. The parking brake letting go after the vehicle is parked is the second recurring theme, followed by front seat belts that will not latch or retract and by exhaust manifold and catalytic converter noise. Most reports come from vehicles with well over 100,000 miles, and several owners say the dealer or manufacturer declined repairs as out of warranty or outside a recall population.

1. 1
   Fuel system

   Fuel smell and leaks at the tank sending unit

   • 32 complaints (21%)
   • median 100,800 mi at 17.1 yrs old (5 state mileage, few)
   • filed 1995–2016

   Owners describe a gasoline smell inside or around the Jeep, often strongest after filling up, and find fuel or vapor escaping at the top of the plastic fuel tank around the sending unit, its gasket and the tank seal. Some report gas running down the back of the vehicle when the pump clicks off, and others had the tank, gasket or sending unit replaced. Several say the dealer or manufacturer checked the VIN against a fuel-system recall and told them their vehicle was not covered, and a few describe the leak appearing or continuing after recall work was done. Mostly reported above roughly 90,000 miles, though a few owners describe the same odor at much lower mileage on vehicles that were already many years old.

   Recall 94V106000

   What to check: After a fill-up, smell around the rear of the vehicle and look for wetness at the top of the tank and around the filler neck. Ask whether the sending unit gasket and tank seals have been replaced, and confirm by VIN whether the fuel-system recall was ever applied.

   “Spoke w/ chrysler and the dealership directly about leak in dashboard. Since my vehicle was out of warranty, neither would do anything about problem w/o having their mechanic inspect the vehicle at a cost of $75/hr. Payable by owner (me). I pointed out all they needed to do was look at the passenger side floorboard to see the puddle of water left after it rained the night before. …”

   NHTSA complaint #758862, filed 2002-03

   “A strong smell of fumes was coming from vehicle, while driving between 45-55mph it cut off without any kind of warning. Vehicle was towed to owners home. There was a problem found with the fuel pump. Upon fuel pump replacement dealer found burnt wires going to fuel pump.”

   Brakes

   Parking brake releases on its own

   • 18 complaints (12%)
   • median 106,400 mi at 16.3 yrs old (2 state mileage, few)
   • 9 mention a crash, fire or injury
   • filed 1999–2016

   Owners report the parking brake letting go by itself after the vehicle is parked, so the Jeep rolls down a driveway or slope, in some cases into a wall, a tree or another parked car. Many describe repeated dealer adjustments that hold for a few days before the lever goes loose again, and some say they now leave the vehicle in gear as well. Complaints reference a parking-brake recall, with owners describing the same behaviour both before and after the repair, and some were told the campaign was too old to cover. Mileage is rarely stated in these reports; the problem is described on parked vehicles ranging from a few years old to over 100,000 miles, usually on slopes or driveways.

   Recall 02V041000

   What to check: Park on a slope, set the brake and wait several minutes to see whether it holds, then check how much lever travel there is. Ask whether the parking-brake recall repair was performed and whether the lever has needed repeated adjustment since.

   “Despite my Jeep Wrangler having been recalled due to faulty parking brakes recall # 02v- 041000, this problem persists. I have taken my car to the dealership numerous times where they tighten the parking brake and each time it eventually slips again. I no park my car in gear which keeps it stationary but every time I am not parked in gear my car rolls away. Many times the brake is on and suddenly come off but plenty of other times the car moves even when the brake is on. …”

   NHTSA complaint #10162891, filed 2006-07

   “The vehicle was parked in a parking lot on a moderately flat surface. The aprking brake had been engaged. I was alerted by local security that my vehicle had rolled out of it's parking spot. It rolled approximately 20 yards into the rear end of another parked car. This parking brake had been fixed one time before. The parking brake does not hold on anything more than a flat surface. It's been fixed repeatedly, but within days of being fixed it will pop and be too loose to hold the vehicle.”

   Seat belts

   Seat belts that will not latch or retract

   • 16 complaints (11%)
   • median 106,250 mi at 8.7 yrs old (4 state mileage, few)
   • 1 mention a crash, fire or injury
   • filed 1995–2004

   Complaints describe front seat belts that fail to stay fastened, release without warning while driving, or will not click at all, and retractors that leave slack hanging on the floor or lock so the belt cannot be pulled out. Owners say a belt sometimes has to be fed back into the retractor by hand, and that dealers told them the belts were not covered and would have to be purchased. One owner reported a shoulder and lap belt that came apart in use, and another had a belt that unlatched unexpectedly. Mostly reported between roughly 85,000 and 135,000 miles on vehicles well over a decade old.

   What to check: Pull each front belt out fully and let it retract, then latch it and tug firmly to confirm it holds. Ask whether any belt, buckle or retractor has been replaced and whether the parts were paid for by the owner.

   “Starting in jan 2004, my drivers side seatbelt disengaged on its own while driving. In the last two months it has done this several times, always without warning. Some times the belt will stay latched for the whole trip, some times it will release before I can reach the end of the driveway, more often it will release while I'm driving on the highway. I have not yet had a chance to speak with a dealer about the problem.”

   NHTSA complaint #10060191, filed 2004-03, 120,000 miles

   “Seatbelt latch and retractor my seatbelt latch does not stay fastened. It will release at any time even if I am not moving. The seatbelt retractor will also lock when the belt is fully retracted and can remain this way for days. Sometimes I have had to drive with no seatbelt! The retractor will also lock when the belt is withdrawn. When this happens the belt has to be manually fed into the belt retractor. I have been to the dealership with my problem and they just tell me that I will have to purchase a new belt. …”

   Engine cooling

   Exhaust manifold cracks and converter rattle

   • 9 complaints (6%)
   • typically at 5.4 yrs old
   • filed 1998–2003

   Owners describe a loud rattle from underneath at start-up, often traced to the catalytic converter, and some have had the converter replaced several times. Others report the welded tubular exhaust manifold cracking at the collector or a stud breaking off, which produces an exhaust leak, extra noise and exhaust smell around the vehicle; one owner noted that the leak can upset the fuel mixture and shorten converter life. According to complaints, some dealers described the manifold failure as a familiar problem on these vehicles. Mileage is seldom given; one owner reported the manifold weld failing near 50,000 miles, and others describe repeat converter replacements over several years.

   What to check: Listen for a rattle or an exhaust tick when the engine is cold, and look for cracks or missing studs where the manifold collector joins the downpipe. Ask how many times the catalytic converter has been replaced and on what diagnosis.

   2 excerpts from owner complaints in NHTSA records

   “The exhaust manifold is a welded tubular header. At approximately 50,000 miles the weld at the collector cracks. I don't know if I am at risk of carbon monoxide poisoning because of this failure. This has happened twice now and it is approximately a 600.00 repair. In talking to the repair dept. At a local dealership, this is a fairly common problem. The same problem has occurred twice to my father's 1997 Jeep Wrangler also.”

   NHTSA complaint #748756, filed 2001-07

   “Exhaust manifold - rear stud on driver's side has broken off leading to an exhaust leak. Causes noise and excess o2 in exhaust system signal computer to increase fuel richness which taxes the catalytic converter, causing early failure. Catalytic conveter has been replaced three times as result. Door locks - the door locks on both the passenger and driver side have broken, making it impossible to unlock door from outside with key. By turning key, the lock begins to disengage, but not enough to unlock door. …”

   Latches, locks and linkages

   Hood and door latches that open on their own

   • 8 complaints (5%)
   • typically at 4.8 yrs old
   • filed 1996–2001

   Complaints describe the exterior hood latches coming undone in motion so the hood lifts into the windshield, and door locks that stop turning with the key or let a door swing open while driving. Owners also mention window regulators that let the glass drop in the door channel and interior grab handles pulling loose, with several dealer visits that did not resolve the problem. Mileage is not stated in these reports; the failures are described on vehicles of this age regardless of distance covered.

   What to check: Open and close both doors and the hood to confirm the latches engage firmly, and try the door locks with the key from outside. Ask whether any latch, lock cylinder or window regulator has been replaced.

   “I feel Wrangler are advertised as rugged - but they are anything but rugged!! Lots of trouble. Chrysler did nothing to help except offer costly repairs (new seat for $1,200 that was cheaply made, fix door locks for $200 that kept breaking and windows that would not roll up or down easily) that I felt should not have been at my expense. Chrysler's answers when I complained were - I used excessive force all the time. The drivers seat broke - first time I reclinded it. …”

   NHTSA complaint #734177, filed 2000-10

   “While consumer was driving, passenger's side door flew open. Locks on doors have failed three times, door has flew open while driving because of failure. Windows fall down in door channel, consumer has taken this problem to the dealer on seven occasions. Air conditioner leaks inside vehicle and has been to dealer on three occasions.”

   NHTSA complaint #801028, filed 1996-08

Buying note. Condition and service history matter more than the model year on a vehicle this old, so check the fuel tank seals and smell, whether the parking brake holds on a slope, and the front seat belts before buying. It is also worth confirming by VIN which recall work has been completed, since much of what owners report involves parts that wear out over time.
