2003 Jeep Wrangler Problems

Miscellaneous -- Verified

Water can leak near the A-pillar, at the front edge of the driver and passenger side doors. An improved seal is available.

Exhaust & Emissions -- Verified

The throttle position sensor (TPS) may fail causing intermittent drivability problems like hard starting, stalling, and/or hesitation when accelerating. A failed TPS will require replacement, proper diagnoses should always be performed before replacing any parts.

Drive Train -- Verified

Leaks at the front and/or rear differential pinion seal and from the transfer case are common. Leakage from the transfer case normally occurs at the case-mating surfaces and require removal of the transfer case to reseal.

Suspension & Steering -- Verified

Loose or worn suspension and steering components can cause a wobble or shaking in the steering wheel. It may happen at a certain speed and subside as the vehicle accelerates through the range. Tire balance can contribute to this as well.

Exhaust & Emissions -- Verified

A ticking type noise may be noted from the engine area due to an exhaust manifold that has cracked where the pipes are welded; cracked manifolds should be replaced.

2003 Jeep Wrangler Reviews

I have owned my 03 Jeep Wrangle for 10 years now. Love the thing. Very reliable vehicle. The inline 6 is a good all around engine. I have done some tough off road driving and tow a small trailer with ease. Fairly simple for the lay mechanic like myself. Only problems are some light issues.

great little ride. Its more like a friend than a vehicle. Fun to drive and very dependible. I love this jeep, and ive owned several over the years.Very few problems. Faulty fan swich after 83,000 miles,batt replacement, and two sets of pricy oversized tires. Some problems with zippers on soft doors. Easy to fix just take a razor blade make a small cut at the bottom of the zipper tape and replace the zipper off some of your old luggage, works great. I used some high quality brass zippers by american tourester. Replaced front brake pads thats it. This has been a no problem vehicle, I know it wont last forever , nothing ever does, but when the time comes i will replace her with a new model just like I did with my wife.
