2003 Jeep Grand Cherokee Engine Problems

Your hydraulic cooling fan stopped working while driving, causing your engine to overheat and requiring a tow truck to get you off the highway. The fan solenoid works when you apply power directly from the battery, but it won't engage when the engine is running, suggesting an electrical connection or control issue rather than a solenoid failure. The repair will likely involve diagnosing the wiring, electrical connectors, or control module that signals the fan to turn on during normal operation.

ENGINE STALLS WITHOUT WARNING, NUMEROUS PARTS REPLACED STILL PERSISTS. VERY DANGEROUS

THE HEATING/COOLING SYSTEM ON MY 2003 GRAND CHEROKEE IS AN INSULT TO THE OTHER QUALITIES OF THIS VEHICLE! THE INTERNAL DOORS THAT DIRECT AIR THROUGH THE SYSTEM IS EXTREMELY CHEAPLY MADE. MOSTLY PLASTIC-A VERY POOR GRADE! THE DEALER SAYS IT WILL COST CLOSE TO A $1000 TO REPAIR AND HE WOULDN'T GUARANTEE IT WOULD NOT HAPPEN AGAIN. I THINK CHRYSLER SHOULD BE RESPONSIBLE FOR SOMETHING THIS POORLY MADE. IT IS NO WONDER THEY ARE IN TROUBLE AND THE GOVERNMENT IS GIVING THEM BILLIONS OF DOLLARS TO MAKE MORE INFERIOR JEEPS! I HAVE NOT HAD THE REPAIRS MADE,I JUST DON'T HAVE THE MONEY. SO MY WIFE HAS TO RIDE TO WORK IN A LUXURY VEHICLE WITH NO HEATER! THERE IS NO DOUBT THIS SHOULD BE A RECALL!!!!! *TR UPDATED 10/23/09 *CN

2003 JEEP GRAND CHEROKEE STALLS WHEN IDLING AT STOP LIGHTS, IT ALSO NEARS STALLING AND THEN LUNGES FORWARD WHEN IDLING. I WAS STUCK IN THE CENTER LANE DURING RUSH HOUR TRAFFIC LAST EVENING WITH MY 2YO IN THE BACK SEAT WHEN MY JEEP STALLED. THIS IS NOT AN UNCOMMON OCCURRENCE, IT HAS HAPPENED EVERY DAY FOR THE LAST MONTH. THIS IS A VERY SERIOUS AND DANGEROUS SITUATION; IT MAKES YOU FEEL AS IF YOU HAVE NO CONTROL OVER YOUR VEHICLE! I AM TAKING IT TO THE DEALERSHIP ON SAT, BUT FROM COMPLAINTS I HAVE READ ON COMSUMERAFFIARS.COM I AM NOT EXPECTING THEM TO BE ABLE TO DO ANYTHING. I HAVE ALREADY CONTACTED JEEP AND EVEN THOUGH THERE ARE RECALLS FOR CERTAIN MODELS FOR THE EXACT SAME PROBLEM MY VIN DOESN'T MATCH UP TO BE ABLE TO DO ANYTHING ABOUT IT. *TR

TL*THE CONTACT OWNS A 2003 JEEP GRAND CHEROKEE. THE CONTACT STATED THAT THE VEHICLE STALLS AND THE RPM'S BEGIN TO RISE SUDDENLY. THE VEHICLE DOES NOT BACKFIRE, JERK, OR MAKE NOISES. THE FAILURE OCCURS WHILE DRIVING AT ANY SPEED. THE CONTACT MUST ACTIVATE THE HAZARD LIGHTS AND RESTART THE ENGINE. USUALLY, THE VEHICLE RESTARTS, BUT SOMETIMES IT TAKES 3 OR 4 ATTEMPTS TO RESTART. THE DEALER REPLACED THE CRANKSHAFT POSITION SENSOR, WHICH REMEDIED THE ISSUE FOR A FEW HOURS. THE FAILURE RECURRED THE SAME DAY SHE RETRIEVED THE VEHICLE FROM THE DEALER. THE CONTACT IS SCHEDULED TO TAKE THE VEHICLE BACK TO THE DEALER, BUT JUST WANTS THE DEFECT TO BE CORRECTED PROPERLY. SHE RESEARCHED THE FAILURE AND FOUND NUMEROUS COMPLAINTS FOR THE ISSUE. SHE BELIEVES A RECALL SHOULD BE ISSUED FOR THE DEFECT. THE CURRENT AND FAILURE MILEAGES WERE 88,442.

TL*THE CONTACT OWNS A 2003 JEEP GRAND CHEROKEE. WHILE DRIVING 45 MPH, THE VEHICLE STALLED WITHOUT WARNING. APPROXIMATELY A FEW SECONDS LATER, THE VEHICLE RESTARTED.

THE CONTACT IS CONCERNED AND DOES NOT WANT TO DRIVE THE VEHICLE IN THIS CONDITION. THE VEHICLE HAS NOT YET BEEN REPAIRED. THE FAILURE MILEAGE WAS 40,000 AND CURRENT MILEAGE WAS 55,000.

I OWN A 2003 JEEP GRAND CHEROKEE WITH THE DUAL CLIMATE CONTROL AND THE BLEND DOORS OF THE HEATING SYSTEM HAVE FAILED CAUSING COOLED AIR OUT ONE SIDE OF THE VEHICLE. THE REPAIR WILL COST ANYWHERE FROM $300 (IF I DO IT MYSELF) UP TO $1500 FOR A DEALER TO FIX IT. THIS IS SUCH A HUGE UNDERTAKING THAT MOST IF NOT ALL OWNERS CAN NOT DO IT THEMSELVES. IN MY RESEARCH I HAVE FOUND THAT AROUND 90% OF JEEP FROM 2000 TO 2004 HAVE THIS PROBLEM. THIS IS NOT A SMALL ISSUE AND THE AUTO MAKER IS FULLY AWARE OF THE FAILING EQUIPMENT INSTALLED IN THESE VEHICLES. THERE EITHER NEEDS TO BE A RECALL TO CORRECT THE PROBLEM OR A CLASS ACTION LAW SUIT AGAINST THE DEALER. *TR

TL*THE CONTACT OWNS A 2003 JEEP GRAND CHEROKEE. THE RADIATOR FAN HAS BURNED OUT TWICE WITHIN 17 MONTHS. THE FIRST TIME IT OCCURRED THE CONTACT WAS PULLING OUT OF A DRIVE THRU AT 10 MPH AND THE VEHICLE BEGAN TO OVERHEAT. THE FOLLOWING DAY, SHE TOOK THE VEHICLE TO THE DEALER AND WAS INFORMED THAT THE AIR CONDITIONER FAN RELAY SWITCH FAILED, WHICH CAUSED THE RADIATOR FAN NOT TO WORK. THE DEALER REPLACED THE FAN AND IT WORKED PROPERLY. HOWEVER, SEVENTEEN MONTHS LATER, THE FAILURE HAS RECURRED. THE VEHICLE IS CURRENTLY AT THE DEALER. THE MANUFACTURER STATED THAT THERE WAS A RECALL FOR THIS FAILURE AND THE CONTACT BELIEVES IT IS DUE TO A MANUFACTURER DEFECT. THE NHTSA CAMPAIGN ID NUMBER WAS NOT FOUND. THE FAILURE MILEAGE WAS 56,000 AND CURRENT MILEAGE WAS 74,000.

TL*THE CONTACT OWNS A 2003 JEEP GRAND CHEROKEE. WHILE DRIVING 55 MPH, THE CONTACT HEARD AN EXPLOSION UNDERNEATH THE HOOD AND OBSERVED PLASTIC PARTICLES COMING FROM HIS VEHICLE. HE PULLED OVER, LIFTED THE HOOD, AND NOTICED THAT THERE WAS A HOLE IN THE RADIATOR AND THE COOLING FAN DISINTEGRATED. THE VEHICLE WAS DRIVEN TO A LOCAL REPAIR SHOP AND THE MECHANIC STATED THAT HE NEEDED TO REPLACE THE RADIATOR AND THE COOLING FAN. THE VEHICLE WAS REPAIRED THE SAME DAY. THE DEALER ADVISED HIM TO CALL THE MANUFACTURER IN REGARDS TO SUBMITTING CLAIMS FOR REIMBURSEMENT. THE MANUFACTURER STATED THAT THERE WOULD BE NO REIMBURSEMENT FOR THE REPAIRS BECAUSE THE VEHICLE WAS NOT INCLUDED IN ANY RECALLS. THE CURRENT MILEAGE WAS 63,000 AND FAILURE MILEAGE WAS 60,020.

CAR STALLS WHILE RUNNING. THIS HAPPENS MOSTLY ON LOW GEAR BUT ALSO HAS HAPPENED WHILE ON THE HIGHWAY. THIS IS A SERIOUS HAZARD TO THE EXTENT I DO NOT WANT MY CHILDREN IN THIS VEHICLE. DO NOT KNOW WHAT TO DO AS I SEE ON THE WEB MANY COMPLAINTS OF THIS NATURE. *TR

MY 2003 JEEP GRAND CHEROKEE LTD IS HAVING PROBLEMS WITH THE DEFROSTER, THE HEATER, AND AIR CONDITIONER. IT HAS DRIVER AND PASSENGER CLIMATE CONTROLS. INITIALLY, THE PASSENGER SIDE STOPPED FUNCTIONING. EVENTUALLY, THE DRIVER SIDE HEAT AND AIR STOPPED WORKING. THE DEFROSTER IS BARELY WORKING AND ONLY ON THE FAN CONTROL. *TR

TL*THE CONTACT OWNS A 2003 JEEP GRAND CHEROKEE. WHILE DRIVING 35 MPH, THE VEHICLE SUDDENLY LOST POWER WITHOUT WARNING. THE DEALER TEST DROVE THE VEHICLE AND IT STALLED. THE CAUSE OF THE FAILURE COULD NOT BE DETERMINED. THE CURRENT AND FAILURE MILEAGES WERE 106,000. UPDATED 4/16/08 *CN THE CONSUMER STATED APPLYING THE GAS PEDAL DOES NOT HELP THE VEHICLE MOVE. THE VEHICLE JERKS AND THE GAUGES MOVE AROUND. THE CAM SENSOR, CRANK SENSOR AND FUEL FILTER HAVE ALL BEEN REPLACED TO NO AVAIL. UPDATED

TOOK VEHICLE TO DEALER FOR REPAIR OF OVERHEATING REPEATEDLY BUT, PROBLEM WAS NEVER FIXED. AFTER CONTACTING SAID DEALER AND WAS TOLD THAT IT COULD DERIVE FROM ONE ZILLION AREAS. CONTACTED DIAMON-CHRYSLER CUSTOMER SERVICE ABOUT THREE MONTHS AGO TO NO AVAIL. *TR

2003 JEEP GRAND CHEROKEE LIMITED, BOUGHT MY JEEP ABOUT 1 A YEAR AND HALF AGO. IT HAS THE DUAL CLIMATE CONTROL THE PROBLEM WITH THE HEAT STARTED IN THE PASSENGER SIDE. IT ONLY BLOWS COLD AIR NOW THE DRIVER SIDE IS OUT TOO. QUOTE FROM DEALER IS IT WILL COST 800- 900 TO REPAIR AND TURNAROUND TIME WAS AT LEAST 2 DAYS. *TR

DUAL ZONE CLIMATE CONTROL IN JEEP GRAND CHEROKEE BLOWS HOT AIR ON DRIVERS SIDE AND COLD ON PASSENGER SIDE WHEN AC IS ON LOWEST TEMPERATURE. THE CAR HAS BEEN IN SEVERAL TIMES FOR THE SAME PROBLEM. THE DEALER JUST REPLACED EVERYTHING IN THE DASHBOARD TO FIX THIS PROBLEM AND I AM HAVING THE SAME ISSUE. MY MAJOR CONCERN IS THAT AS THE WINTER APPROACHES THE WINDOWS WILL FOG MORE AND ICE UP. THE INPROPER HEATING AND COOLING WILL NOT DEFROST THE WINDOWS CAUSING A DANGEROUS SITUATION FOR DRIVING. MY WIFE USES THIS CAR TO DRIVE MY CHILD AND I DO NOT WANT TO RISK THIER SAFETY. THERE ARE WEBSITES ALL OVER LISTING PEOPLE WITH THE SAME PROBLEM FOR YEARS.

I HAVE HAD THE VEHICLE FOR ABOUT 8 MONTHS AND IN THAT TIME BOTH FRONT WINDOWS WENT OUT AND THE RADIATOR FAN RELAY FAILED.*AK

RADIATOR COOLING FAN RELAY HAS BEEN FIXED 3 TIMES IN THE LAST 3 YEARS. *AK

FUMES ENTERED THE CABIN OF THE VEHICLE THROUGH THE VENTS. THE FUMES MADE THE DRIVER NAUSEOUS AND MADE HER FEEL AS THOUGH SHE WAS GOING TO PASS OUT. THE VEHICLE WAS TAKEN IN FOR TESTING, BUT THE CAUSE WAS UNDETERMINED. THE ENGINE LIGHT CAME ON. THE CONSUMER STATED THAT THERE WAS A HOLE IN THE HOSE. *TC VEHICLE CAUGHT ON FIRE WHILE PARKED. THE VEHICLE WAS DEEMED A TOTAL LOSS. THE POWER WINDOW SHORTED OUT PRIOR TO THE FIRE. *NM

MY 2003 JEEP GRAND CHEROKEE, WITH LESS THAN 33,000 MILES, WAS REPAIRED FOR THE SAME PROBLEM TWICE THIS YEAR, ON 9 FEB AND 26 JUL 2005. THE REPAIRS WERE DONE AT 2 DIFFERENT JEEP-CERTIFIED SERVICE FACILITIES, AND FOCUSED ON DECARBONIZATION CLEANINGS. BASED ON THE INVOICES AND MY OWN RESEARCH, IT'S CLEAR THIS PROBLEM HAS SEVERAL INTERRELATED FACTORS: MULTIPLE CYLINDER MISFIRES, AND EXHAUST VALVE OBSTRUCTION WITH EXCESSIVE CARBON BUILDUP. FURTHER, IT IS DIRECTLY LINKED TO SHORT-TRIP/CITY DRIVING. A FEW WEEKS AFTER THE SECOND REPAIR, I HAD AN INDEPENDENT (NON-JEEP) ACE-CERTIFIED MECHANIC INSPECTION. HIS FINDINGS INDICATE THAT THE MISFIRES CONTINUE; THE UNDERLYING PROBLEM APPARENTLY PERSISTS. IN THE BIG PICTURE, JEEP DID ACKNOWLEDGE THE PROBLEM IN TSB-09-003-03, ENCOMPASSING A SPAN OF MODELS, FROM 1999 TO 2004, W/ 4.0L ENGINES. THE TSB PRESCRIBES A VALVE CHECK AND POSSIBLE CLEANING, BUT DOES NOT ADDRESS THE ROOT CAUSE OF THE MISFIRES AND CARBON BUILD-UP. IN THE SMALLER PICTURE, I MIGHT MENTION: THE JEEP REPRESENTATIVE A/W THE JULY REPAIR TOLD ME THIS PROBLEM WAS THE RESULT OF USING 'CHEAP GASOLINE'. THIS THEORY IS NOT SUPPORTED BY ANYTHING I'VE LEARNED IN MY OWN RESERACH. IT IS JUST NOT FEASIBLE THAT GASOLINE GRADE COULD CAUSE SUCH AN EXTENT OF CARBON BUILD-UP TWICE IN 6 MONTHS, ESP WITH SUCH LOW MILEAGE. I SHOULD PROBABLY ALSO ADD THAT I DON'T KNOW THE ABSOLUTE ANSWER TO THIS PROBLEM. THERE IS A GOOD DEAL OF REFERENCE MATERIAL ONLINE ID'ING THIS AS A CHRONIC PROBLEM W/ GRAND CHEROKEE, YET NO CLEARCUT PERMANENT SOLUTION. I HAVE SUPPORTING DOCUMENTATION ON WHAT I STATE HERE, AND WILL BE HAPPY TO FOLLOW UP IN WRITING IF THAT WILL HELP. LASTLY- SINCE MOST OF MY VEHICLE USE IS SHORT-TRIP CITY DRIVING, I AM WORRIED THAT I MAY FACE LONG-TERM INCONVENIENCE, EXPENSE, AND SAFETY RISKS. MY INTENT IS NOT TO CAUSE PROBLEMS FOR JEEP- I SIMPLY WANT MY VEHICLE TO BE FUNCTIONING AND SAFE FOR MY FAMILY. *JB

DT: CONSUMER STATES: VEHICLE CUTS OFF WHILE GOING DOWN THE HIGHWAY, NO WARNING, DOING ALMOST 70 MPH. NOTHING WORKED, AND THERE WERE NO BRAKES. THE ONLY THING WORKING WAS THE 4-WAY FLASHERS. TRIED TO TURN STEERING WHEEL AND LOST POWER STEERING. ANOTHER TIME WENT TO TURN IN THE POSITION THE WHEELS WERE AND IN THAT WAS THE WAY THE VEHICLE WENT. THE REPAIR SHOP MECHANIC SAID IT NEEDED A CRANK SENSOR. PREVIOUSLY, BEFORE THEY PUT IN A FUSE AND IT BLEW OUT. *AK

THE RELAY SWITCH FAILED TO OPERATE WHICH CAUSED THE VEHICLE TO OVERHEAT. THE MANUFACTURER WAS CONTACTED BY OWNER AND WAS AWARE OF THE PROBLEM. *JB

WHILE DRIVING 50 MPH, THE VEHICLE STALLED. THE DRIVER TRIED TO RESTART THE VEHICLE AND WAS ABLE TO START. THE VEHICLE WAS TAKEN TO THE DEALER FOR INSPECTION. THE MECHANIC CAN NOT DUPLICATE THE PROBLEM. PLEASE PROVIDE FURTHER DETAILS. *NM

WHEN DRIVING AT ANY SPEED CHECK ENGINE LIGHT APPEARED ON THE DASHBOARD, THEN, VEHICLE JERKED AND LOST POWER. THE CONSUMER HAD THE VEHICLE WAS TOWED TO THE DEALERSHIP ON TWO OCCASIONS, BUT PROBLEM RECURRED. *AK

PURCHASED A 2003 JEEP GRAND CHEROKEE LIMITED FROM CARMAX ON SEPT 30TH 2002. IMMEDIATELY AFTER PURCHASING THE VEHICLE, A HIGH PITCH SOUND STARTED TO BE HEARD WHILE THE CAR IS IDLING. I'VE TAKEN THE CAR TO TWO DIFFERENT DEALERS APPROXIMATELY A TOTAL OF FIVE TIMES OR MORE AND NO ONE AT THE DEALERSHIP WAS ABLE TO PIN POINT THE PROBLEM. INITIALLY, THE DEALER THOUGHT THE NOISE MIGHT BE RELATED TO THE BELT, BUT ONCE THE BELT WAS CHANGED THE NOISE PERSISTED. THE ENGINE WAS ALSO CHECKED AND UNFORTUNATELY THE NOISE IS STILL BEING HEARD AND IT IS MORE PRONOUNCED. THEN ON TOP OF EVERYTHING ELSE, THE HEATING VENT ON THE PASSENGER SIDE HAS MALFUNCTIONED CONVIENTLY AFTER THE WARRANTY JUST RECENTLY EXPIRED. IN ADDITION ON MARCH 12TH 2004, UPON BRINGING MY TRUCK INTO THE DEALERSHIP FOR SERVICING, THE MACHANIC SCRAPS THE SIDE OF THE TRUCK REMOVING THE PAINT OFF OF THE REAR PASSENGER DOOR AND ANTWERPEN JEEP DOESN'T WANT TO COMPENSATE ME. PLEASE ADVISE. ANY INFO THAT YOU WOULD BE ABLE TO PROVIDE WOULD BE GREATLY APPRECIATED. THIS HAS NOT BEEN A GOOD EXPERIENCE FOR ME. I PURCHASED A NEW FORD MUSTANG IN 1997 AND WAS COMPLETELY SATISFIED, HAD NO PROBLEMS WITH THE CAR AND THE SERVICE WAS EXCEPTIONAL.*AK

LOUD TAPPING NOISE EMITTED BY THE EMISSIONS CANISTER UNDER THE HOOD ON DRIVERS SIDE.
