2003 Jeep Wrangler Problems

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

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.

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.

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.
