TL* THE CONTACT OWNS A 2001 JEEP GRAND CHEROKEE. WHILE DRIVING APPROXIMATELY 5 MPH THE VEHICLE SUDDENLY STALLED. THE CONTACT WAS ABLE TO DRIVE ONTO THE SHOULDER WITHOUT INCIDENT. THE VEHICLE WAS TOWED TO THE DEALER. THE TECHNICIANS WERE UNABLE TO DUPLICATE OR DIAGNOSE THE FAILURE. THE FAILURE CONTINUED TO OCCUR. THE VEHICLE WAS TAKEN TO THE DEALER THREE TIMES.

CAR STARTED TO RUN REALLY BAD THEN WHEN I TRIED TO CRANK IT BACKUP IT RAN FOR A FEW MINUTES AND DIED. I NOTICED GAS THEN FLAMES COMING FROM EXHAUST PIPE. IT WILL RUN FOR FEW MINUTES BUT REALLY BAD , THEN IT WILL DIE. IT WANT CRANK IMMEDIATELY AFTER IT DIES YOU HAVE TO WAIT A WHILE BEFORE IT WILL CRANK AGAIN. I HAVEN'T BEEN ABLE TO FIND OUT WHAT THE PROBLEMS ARE TO CORRECT THEM. *TR

THE HEAD CRACKING ISSUE SEEMS TO BE THE RESULT OF SEVERAL BAD CASTINGS AND I CAN ONLY SPECULATE THAT THE CAST IRON USED IN ONE LARGE BATCH MADE AROUND THE YEAR 2000 MUST HAVE BEEN OF POOR QUALITY. THE AREA BETWEEN THE NO.3 AND 4 EXHAUST PORTS IS THE HOTTEST PART OF THE HEAD AND IS SUBJECTED TO THE LARGEST TEMPERATURE FLUCTUATIONS, MAKING THAT THE AREA MOST PRONE TO CRACK. THE FIRST SIGN OF A PROBLEM IS UNEXPLAINED LOSS OF COOLANT. IF THERE ARE NO EXTERNAL COOLANT LEAKS, REMOVE THE OIL FILLER CAP AND LOOK BETWEEN THE VALVE SPRINGS OF THE NO.3 AND 4 CYLINDERS.

REPEATED FAILURE OF BLOWER FAN FOR WHICH THERE IS APPARENTLY NOT A SUITABLE FIX FROM JEEP. CURRENT FIX IS EITHER (A) PART FROM SUPPLIER OTHER THAN JEEP WHICH FAILS EVERY 6-9 MONTHS OR (B) JEEP RECOMMENDED PART WHICH REDUCED AIR VOLUME SO DRAMATICALLY THAT DEFROSTING WINDOWS IS UNSAFE. FAILURE OF THE BLOWER MOTOR IS ALSO UNSAFE DUE TO THE INABILITY TO DEFROST THE WINDOWS. *TR

THE CAR OVERHEATED AND YOU CAN HEAR THE BOILED COOLANT FLUSHING BACK INTO THE RESERVOIR AND POURING OUT THROUGH THE DRAIN. THIS I FOUND OUT WAS CAUSED DUE TO THE MALFUNCTIONING OR RATHER ELECTRICAL SHORTING OF THE ECM (ENGINE CONTROL MODULE) LOCATED IN THE HOOD NEAR THE FIREWALL BEHIND THE COOLANT RESERVOIR. THIS CAUSES A FAILURE IN THE ELECTRICAL SYSTEM SO THE FAN THAT IS SUPPOSED TO KICK ON WHEN YOU TURN ON THE AIR FAILS TO START. I ALSO RECENTLY REPLACED MY INLINE-6 DUE TO A CRACK IN THE ENGINE BLOCK CAUSING THE COOLANT TO FLOW AND MIX WITH THE OIL THEREFORE, RESULTING IN LOW LEVELS OR COOLANT IN THE RESERVE AND THE RADIATOR. IT ALSO CAUSES THE OIL LEVEL TO INCREASE DRASTICALLY. *TR

TL* THE CONTACT OWNS A 2001 JEEP GRAND CHEROKEE. WHILE DRIVING APPROXIMATELY BETWEEN 25 AND 30 MPH ON NORMAL ROAD CONDITIONS. THE ENTIRE WARNING LIGHT INDICATOR ILLUMINATED ON THE INSTRUMENT PANEL. SUDDENLY, THE COMPLETE ELECTRICAL SYSTEM FAILED TO FUNCTION. THE DRIVER PULLED OVER TO THE SIDE OF THE ROAD. THE VEHICLE RESUMED NORMAL OPERATION AFTER A DELAY OF FIFTEEN SECONDS. THE FAILURE OCCURRED INTERMITTENTLY. IN ADDITION, THE ACTIVATION OF THE WINDSHIELD WIPERS ALSO RESULTED IN THE ENGINE STALLING. PREVIOUSLY, THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC ON THREE SEPARATE OCCASIONS FOR THE IDENTICAL FAILURES AND THE TECHNICIAN WAS UNABLE TO DUPLICATE THE FAILURES. THE VEHICLE WAS REPAIRED FOR THE MALFUNCTIONS WHEN THE COMPLAINT WAS FILED. THE FAILURE MILEAGE WAS 65,000. UPDATED 03/12/10. *LJUPDATED 09/16/10

I OWN A 2001 JEEP GRAND CHEROKEE WITH A 4.0L 6 CYLINDER MOTOR. THE ENGINE HAS BEEN SHOWING ZERO OIL PRESSURE, AFTER REPLACING 2 OIL PRESSURE SWITCHES, AND AN OIL PUMP. THE VEHICLE CONSTANTLY OVERHEATS. NOW, IT WAS SUGGESTED BY THE DEALER THE CYLINDER HEAD MY BE CRACKED. AFTER READING ABOUT MY VEHICLE ON-LINE, THERE ARE MORE THAN NUMEROUS SIMILAR INCIDENTS WITH OTHER JEEP OWNERS. *TR

CRACKED HEADS ON A 2001 JEEP GRAND CHEROKEE ANTIFREEZE LEAKING AND DIDN'T KNOW WHERE IT WAS GOING NO LEAKS. *TR

TL*THE CONTACT OWNS A 2001 JEEP GRAND CHEROKEE. WHILE THE ENGINE WAS RUNNING, THE FAN BLADE SEPARATED AND CAUSED THE ENGINE COOLING SYSTEM TO FAIL. THE VEHICLE THEN BEGAN TO OVERHEAT. THE FAN WAS FIRST REPLACED IN JUNE OF 2006. NHTSA CAMPAIGN ID NUMBER 06E011000 (FUEL SYSTEM, GASOLINE:DELIVERY:FUEL PUMP) WAS RECEIVED IN JUNE OF 2007.

LOOSING APPROXIMATELY 1 GALLON OF ANTIFREEZE PER 1000 MILES. DEALER REPAIRS NUMBER OF TIMES STARTING FROM PURCHASE AT 19,000 MILES (WAS TOLD TO AY $268 BY CUSTOMER SERVICE TO REPLACE RADIATOR WHEN FINALLY DIAGNOSED AT 40,000 MILES TO GET VEHICLE BACK EVEN THOUGH IT WAS UNDER WARRANTY AND VEHICLE IS STILL LOSING SAME AMOUNT OF COOLANT)/ LOW OIL PRESSURE WAS FINALLY CORRECTED BY REPLACING UNDERSIZED CAM...DIDN'T REPLACE LIFTERS, ETC... INCORRECT PROCEDURE BECAUSE THEY WEAR TOGETHER/ A/C AND CRUISE FIXED BY ZIP TYING A LARGE VACUUM RESEVOIR BOTTLE TO A/C LINE/TRANSMISSION SHIFT POORLY.

SENT JEEP GRAND CHERROKEE LAREDO TO JAY WOLFE JEEP ON JAN 31 2003 TO CHECK OUT LOW OIL PRESSURE INDICATOR WHICH COMES ON DAILY AND LOW COOLANT WHICH COMES ON EVERY SO OFTEN. VEHICLE HAS BETWEEN 48000 AND 49000 MILES ON IT. WAS TOLD IT WAS SENDING UNIT THEN GOT CALL SAYING THAT IT WASNT AND WOULD HAVE TO DROP OIL PAN. WAS ALSO TOLD NO SIGN OF COOLANT LEAK OR MIX WITH OIL. I NOW HAVE RECIEVED CALL INDICATING THAT IT COULD BE BLOWN HEAD GASKET WITH MILES INDICATED ABOVE. AFTER FURTHER INQUIRE I FOUND THAT NONE OF THE BASIC TESTING WAS DONE TO CHECK FOR OIL AND COOLANT MIX, THIS WAS ADMITED TO ME BY JEFF WHO IS ONE OF THE SERVICE ATTTENDANTS. JEEP SHOULD BE THE ONE PAYING FOR A BLOWN HEAD GASKET WHEN THE CAR HAS THESE LOW MILES ON IT. JEEP DEALER SHOULD ALSO BE...
