1998 Jeep Grand Cherokee fuel system, other problems

“1998 JEEP GRAND CHEROKEE, 2WD, 4.0 LITER INLINE 6, AUTOMATIC TRANSMISSION. USER HAS REPLACED MANY ENGINE ELECTRICAL AND IGNITION PARTS, AS WELL AS FUEL PUMP ASSEMBLY, SOME RELAYS, AND THE JEEP CONTINUES TO STALL IN TRAFFIC, WHEN TURNING CORNERS, WHEN BACKING UP, HAS INTERMITTENT STALLING WHEN DRIVING, AND IS POSTING VARIOUS COMPUTER CODES. I HAVE ALREADY SPENT $700 ON DIAGNOSTIC AND PARTS REPLACEMENT, YET THE PROBLEM PERSISTS. WHEN DRIVING THE ENGINE PERIODICALLY CUTS OUT AND RPM'S DROP TO ZERO. IF THIS HAPPENS IN HEAVY TRAFFIC OR DURING AN EVASIVE MANEUVER SOMEONE COULD BE KILLED. THIS IS AN ONGOING AND DANGEROUS PROBLEM THAT MY MECHANIC CAN NOT FIX, AND BASED ON MY RESEARCH ON THE INTERNET IT IS A WIDESPREAD AND PERPLEXING DESIGN-RELATED PROBLEM WITH THIS ERA JEEP CHEROKEES AND GRANDS. *TR”

“WHILE DRIVING FUEL GAGE FLUCTUATES LEAVING THE CONSUMER WITH NO KNOWLEDGE OF HOW MUCH GAS IS IN THE GAS TANK. ALSO, THE ELECTRICAL LOCKING MECHANISM FOR THE DOORS MALFUNCTIONED. UPON USING THE AUTOMATIC LOCK BUTTON, IT WILL NOT LOCK UNLESS CONSUMER GETS OUT OF THE VEHICLE, AND USES THE KEY. ALSO, CONSUMER HAS TO USE THE KEY TO LOCK THE TAILGATE. *AK THE CONSUMER SITED THE RECALL FOR THE FUELGAGE NEEDED TO FIX THE VEHICLE. THE VEHICLE WAS NOT COVERED UNDER THE RECALL FOR THE CONSUMERS VEHICLE. *TC”

“THE FUEL GAUGE WILL RANDOMLY GO FROM THE CORRECT READING TO EMPTY ALONG WITH THE CHIME TELLING THE DRIVER TO STOP FOR REFUELING SOON. I NOW SEE THAT I AM NOT THE ONLY ONE GOING THROUGH THIS. WILL CALL THE DEALER ON MONDAY. CLH. *AK”

“THE GAS GAUGE ON MY JEEP DOES NOT ACCURATELY REFLECT THE AMOUNT OF GAS LEFT. THE TANK MAY REPORT THERE IS GAS REMAINING WHEN EMPTY OR THAT THERE IS NO GAS WHEN FULL. THE GAUGE MAY START AND STOP WORKING SEVERAL TIMES WHILE DRIVING IN A SINGLE TRIP, OR NEVER ACCURATELY REPORT THE GAS LEVEL AT ALL. *LA”

“WHEN I BOUGH MY VEHICLE 2 YEARS AGO THE GAS GAUGE NEEDLE WOULD GO TO EMPTY, THE BELL WOULD RING, THEN GO BACK TO FULL A FEW TIMES. DEALER SAID SINCE I BOUGHT THE CAR USED, AND IT WASN'T A SAFETY ISSUE, THEY WOULD NOT COVER IT IN THE 30 DAY WARRANTY. NOW THE NEEDLE IS ONLY CORRENCT WHEN IT IS FULL. ALSO, ALL 4 TIRES SEEM TO LOSE AIR QUICKLY. BROUGHT IT TO THE DEALER TWICE. FIRST TIME COULDN'T FIND A PROBLEM, SECOND TIME THEY REPLACED THE STEMS. NOW STILL HAVE THE PROBLEM. PRETTY MUCH SICK OF WASTING MY TIME BRINGING IT SOMEWHERE AND THEY CAN'T FIGURE OUT THE PROBLEM.*AK”

“1. FUEL INJECTOR FAILED CAUSING THE ENGINE TO MISFIRE AND OPERATE ON ONLY 5 OUT OF 6 CYLINDERS. 2. IN THE SAME CYLINDER (#6) ROD BROKE, CAUSING ENGINE TO BLOW AND NEED REPLACEMENT AT ONLY 42,000 MILES. 3. POWER STEERING PUMP ALMOST FELL OFF THE VEHICLE. (MOST LIKELY DUE TO IMPROPER INSTALLATION AFTER ENGINE REBUILD). 4. BRAKES CONSTANTLY SQUEAK OR MAKE GRINDING NOISE WHEN PRESSURE IS APPLIED. WHEN TEMPERATURES ARE BELOW 50 DEGREES, A HIGH PITCHED WHINNING NOISE IS HEARD FROM UNDERNEATH THE VEHICLE. CAN ONLY BE HEARD WHEN TRAVELING UNDER 45 MPH - DUE TO ROAD NOISE MASKING THE SOUND. (MULTIPLE DEALERS HAVE NOT BEEN ABLE TO DETERMINE WHAT THE PROBLEM IS NOR BE ABLE TO FIX IT, SO CONSTANTLY WHINES). 5. FUEL GAUGE FLUCTUATES WHEN 3/4 FULL (DROPS TO EMPTY AND FUEL LIGHT TURNS ON, THEN RETURNS TO NORMAL READING. WILL CONTINUE TO DO THIS UNTIL TANK IS 1/4 FULL). TOLD THIS IS A PROBLEM WITH THE FUEL SENSOR. 6. TRANSMISSION IS OCCASIONALLY ROUGH (JERKY SHIFTING BETWEEN 1ST AND 2ND GEARS).*JB”
