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.
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.
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.

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.
