Three problems related to tank filler pipe and cap have been reported for the 1998 Jeep Cherokee. The most recently reported issues are listed below.
Standard Jeep Cherokee (had been maintained by us gvt. Until I bought) hesitates or stalls when turning when gas tank below 25-35% . Is hazardous and have nearly been rearended a few times, from 2003 thru 2009. Chrysler says known problem with fuel filter/pump 'sock'--but no assistance in the 500$ plus potential repair costs. This is the biggest safety problem I have ever heard of in a modern car and it's rampant among Cherokee owners.
On hot days the front brakes lock up and would not release, causing linings to smoke. When the air conditioner is on, the compressor kicks in at night while driving with the headlights on. When filling the gas tank, the filler pipe makes a slurping sound, causing the gasoline to slush back and forth in the gas tank.
Fuel filler neck broke.
