1993 Jeep Wrangler Problems

What owners report

Owners of this model year most often describe fuel leaks and fuel vapors around the plastic fuel tank and sending unit, a parking brake that lets the vehicle roll, and seat belt retractors and buckles that jam. Many of these reports involve trucks with well over 100,000 miles, and several describe symptoms that returned after an earlier recall repair rather than appearing suddenly on a low-mileage vehicle.

1. 1
   Fuel system

   Fuel leaks and vapor at the tank / sending unit

   Mentioned in 14 of 51 sampled complaints

   Owners describe fuel or fuel vapors coming from the top of the tank, often after refueling or when the tank is full, and some link it to a cracked sending unit gasket or a collapsed plastic tank. Several say the leak appeared after recall 94V106000 work was done, or that their vehicle was not covered by that campaign. Complaints also describe fuel lines at the tank ends that were not clamped from the factory working loose as the rubber aged. Dealers and mechanics reportedly replaced the tank or sending unit in some cases, and some owners were told the parts are no longer available. Reports span the whole mileage range, with several at 93,000 to 160,000 miles and many at unknown mileage; no clear season or age pattern in the sample.

   Recall 94V106000

   What to check: Inspect the top of the tank and the sending unit area for wetness or a fuel smell, especially right after a fill-up, and ask whether recall 94V106000 was completed and whether the tank or sending unit has been replaced since.

   “Hello, I purchased a used Jeep in may 2018. Once I took possession of the Jeep, my mechanic mentioned there was an open recall. So, I called the local dealer about repairing the recall defect. I was told they couldn't help me because the Jeep was to old and they didn't have the parts on hand. They told me to call the Jeep recall center, which I did... And and they too told me the same thing... Too old and no parts on hand. They also told me to call auto parts stores to see if they had the parts and maybe they would reimburse me and maybe not. …”

   Brakes

   Parking brake releases or will not hold

   • 11 complaints (10%)
   • median 122,641 mi at 15.3 yrs old (3 state mileage, few)
   • 4 mention a crash, fire or injury
   • filed 2000–2024

   Owners report the parking brake letting go on its own, or failing to engage at all, sometimes with the vehicle parked on a slope and rolling into another vehicle or object. Complaints describe the pedal assembly and the release mechanism as the area involved, and some note that the problem came back after a recall repair. Owners also report difficulties getting the remedy performed, including being told parts were unavailable or that the nearest repair facility was far away. Reported across a wide mileage range with most mileages unrecorded; several owners describe the release becoming more frequent over time.

   Recall 02V041000

   What to check: Test the parking brake on a slope with the transmission in gear and ask whether recall 02V041000 was completed; check that the pedal holds and that the release mechanism does not pop on its own.

   “Parking brake has failed repeatedly leading to a rolling accident in 12/2001. No other roll-a-ways lead to accidents, but did on several occasion lead to minor damage. Local dealer and factory representatives had nothing to save regarding repairs or liability. I personally know several other Wrangler owners with the same problem and have asked the to report to NHTSA directly. Please keep me posted on developments. Thanks norm”

   Seat belts

   Seat belts lock up or will not retract

   • 13 complaints (12%)
   • typically at 4.7 yrs old
   • 1 mention a crash, fire or injury
   • filed 1995–2002

   Owners describe shoulder belts that lock and will not pull out or retract, buckles that stick and will not release the occupant, and a buckle release button that broke so the belt would not latch. Some had the same problem repaired more than once, in a few cases several visits to the dealer. One complaint describes a shoulder harness that did not hold an occupant in a frontal collision. Mostly reported on vehicles with no mileage recorded, spread across the 1990s and early 2000s; no clear mileage threshold in the sample.

   What to check: Pull each belt all the way out and let it retract, then latch and release every buckle; ask whether any belt, retractor or buckle has been replaced.

   “The driver was stuck in seat for an hour due to the buckle not releasing him. Owner had to lay seat all the way back in order to slide out of belt. Dealer has not seen vehicle. Buckle still stuck.”

   “While getting into vehicle, shoulder belt locked up and will not retract either way; taken to dealer & had problem fixed before, but problem has reappeared.”

   Engine cooling

   Cooling system leaks and overheating

   Mentioned in 6 of 51 sampled complaints

   Complaints describe recurring coolant leaks that persist after replacing the radiator, hoses, water pump, thermostat and freeze plugs, with the source not identified. Owners also report exhaust manifold cracks and broken manifold bolts producing a loud cold-start noise and oil on the engine, and one report describes an A/C line rubbing through against the fender. Reported from low mileage up to about 125,000 miles; the recurring coolant leak complaint covers roughly two years of repeated repairs.

   1 related service bulletin

   What to check: Check coolant level and look for residue around the radiator, hoses and freeze plugs after a drive, listen for a ticking or loud exhaust note at cold start, and ask about prior cooling system and exhaust manifold work.

   “Engine started to sound louder than normal when starting up from a cold start. Noticed engine was covered in oil. When I took it to be repaired, the mechanic told me that the manifold exhaust bolt had failed and that caused my problem. Had it repaired for $300.00. Then I found out about the technical service bulletin from a Jeep website about this problem.”

   NHTSA complaint #743636, filed 2001-04

   “The catalytic converter was replaced on a NHTSA recall. However, problem recurred, per the dealer. Manufactured was contacted, and consumer has been informed that recalls were a one time repair at no cost. No recalls for the part mentioned.”

   Transmission and drivetrain

   Clutch and gearbox engagement problems

   • 11 complaints (10%)
   • typically at 6.4 yrs old
   • 3 mention a crash, fire or injury
   • filed 1995–2002

   Owners describe the clutch pedal linkage detaching so the pedal goes to the floor and the clutch stops working, requiring a tow and replacement of the clutch master cylinder. Others report the vehicle lurching forward when started in gear, hard engagement into first gear, and a broken retainer clip inside the transmission that kept fifth gear from engaging. One transmission shop reportedly said the clip failure is a common one. Reported across a wide range of mileages, mostly unrecorded in the sample; no seasonal pattern described.

   What to check: Check pedal feel and free play, make sure the clutch fully disengages when starting in gear, and test that all gears including fifth engage without grinding; ask whether the clutch hydraulics or transmission have been serviced.

   2 excerpts from owner complaints in NHTSA records

   “The Jeep was parked in garage and had worked okay the day before. I started engine with clutch depressed and the vehicle rammed forward hitting a door in the garage and narrowly missing a gas waterheater. Mechanic later said the clutch bearing cracked (very rare he claims). The clutch was ruined, the flywheel and the total cost to fix was $1200.00. The door will cost $500. The danger from hitting the water heater was extreme and I would have been trapped in the vehicle would there have been a fire. …”

   NHTSA complaint #736371, filed 2000-11

   “Retainer clip broke off main shaft, causing fifth gear not to engage. The vehicle was taken to a transmission shop for repair. Pieces of the clip were found in transmission case. The transmission technician ordered a replacement retainer clip from chrysler parts, and was informed that this problem occurs frequently. The charge for the retainer clip was $4.87. The cost to remove, repair, and replace the transmission was $400 plus gear oil and taxes. …”

   NHTSA complaint #703505, filed 1999-02

Buying note. Look closely at the fuel tank and sending unit area for leaks or a fuel smell, test the parking brake holding on a slope, and check that every seat belt latches and retracts. Confirm which recalls were actually performed on the specific vehicle, since several owners report symptoms returning after the recall work.
