NHTSA Complaint #10252069 — 2000 JEEP CHEROKEE

LOW OIL PRESSURE: I CHANGE MY OIL AS SPECIFIED IN MANUAL. NOW ALL OF A SUDDEN I HAVE A DROP IN OIL PRESSURE. WHEN DRIVING THE JEEP MY OIL PRESSURE IS NOW AT NO MORE THAN 25PSI AND IT DROPS TO ZERO WHEN IDLE. ON MY LAST OIL CHANGE I HAD THE ENGINE CHECKED AND THERE WERE NO CRACKS AND NO MISFIRE. I HAD A TUNE UP DONE ON THE VEHICLE IN SEPT 2008. ENGINE AND EVERYTHING WAS RUNNING FINE. AS FOR THAT DAY I HAVE TO GET THE JEEP TO MECHANIC TO TAKE A LOOK. THIS PAST SUMMER THE JEEP ALSO WOULD OVER HEAT IN 90 DEGREE WEATHER AND IT MOSTLY HAPPENED WHEN THE AC WAS TURNED ON. TOOK IT MECHANIC AND COULDN'T FIND ANYTHING WRONG WE REPLACED THE THERMOSTAT WITH A LOWER TEMP AND SEEMED TO FIX THE PROBLEM. THEN ABOUT 2 DAYS LATER THE JEEP STARTED TO OVERHEAT AGAIN. REPLACED THE RELAY AS IT TESTED BAD. WHILE REPLACING THE RELAY THE FAN BROKE. THE BLADES COMPLETELY SEPARATED FROM THE FAN MOTOR IN A WHOLE PIECE. REPLACED FAN. NEVER THOUGHT I HAD ANY COOLANT LEAKS AND NEVER FOUND ANY BUT THE COOLANT WILL NOT STAY IN THE RESERVOIR. IT JUST DISAPPEARS. I HAD THE ENGINE INSPECTED AGAIN AND NO CRACKS AND THE OIL APPEARED TO BE FINE. THERE ARE THOUSANDS OF COMPLAINTS FOR THIS WHAT IS GOING TO BE DONE? ANYTHING? IT'S NOT LIKE I CAN AFFORD ANEW CAR OR THOUSANDS IN PARTS AND LABOR. ALSO HAVE OTHER ISSUES I WELL 1ST ANOTHER COMPLAINT FOR THE ELECTRICAL ISSUES. *TR
