2007 Jeep Grand Cherokee engine and engine cooling problems

“I BOUGHT A USED 2007 JEEP GRAND CHEROKEE 2 YEARS AGO IN ALABAMA. WE HAVE SINCE MOVED TO NEW YORK STATE AND THEY DO VEHICLE INSPECTIONS (ALABAMA DOES NOT). WHEN GETTING THE VEHICLE INSPECTED IT WAS DISCOVERED THAT THE CUT OUT FOR THE CHECK ENGINE LIGHT ON THE INSTRUMENT PANEL IS NON EXISTENT. ALL OTHER CUT OUTS ARE PRESENT AND THE LED FOR THE CHECK ENGINE LIGHT IS PRESENT AND WORKING. THE INSTRUMENT PANEL IS STAMPED AS BEING ORIGINAL AND NOT AFTERMARKET. BECAUSE THERE IS NOT A CUT OUT THE LED FOR THE CHECK ENGINE LIGHT IS NOT VISIBLE WITH THE INSTRUMENT PANEL INSTALLED AND WILL NOT PASS INSPECTION. I HAVE CONTACTED MY LOCAL JEEP DEALERSHIP (FX CAPRARA) AND THEY TOLD ME TODAY THAT I HAVE TO PAY TO FIX IT. A NEW PANEL BEING $600 AND A USED PANEL FROM MY LOCAL PICK AND PULL BEING $125. I CALLED JEEP CUSTOMER SERVICE TODAY AND THEY AGAIN TOLD ME JEEP CAN'T DO ANYTHING AND THAT IT IS UP TO THE DEALERSHIPS. I DON'T UNDERSTAND WHY IT WOULD BE UP TO ME TO PAY FOR THIS. IT IS A MANUFACTURER DEFECT AND SHOULD BE CORRECTED ON THAT LEVEL. I DID MY DUE DILIGENCE WHEN PURCHASING THE CAR BUT ONE CANNOT BE EXPECTED TO PULL THE DASH PANEL TO ENSURE ALL THE CUT OUTS ARE PRESENT.…”

“WHILE DRIVING THE VEHICLE IT STARTED TO ACCELERATE AND WHILE STEPPING ON THE BRAKE THE VEHICLE WENT FASTER. I TURNED THE KEY AND THE ENGINE STOPPED AND I WENT TO THE SIDE OF THE ROAD. I LOOKED UP A RECALL FOR THIS PROBLEM AND THERE WAS A K 11 RECALL. WHEN I CONTACTED JEEP THEY SAID MY VIN NUMBER WAS NOT PART OF THE RECALL. WELL I THINK THERE IS A PROBLEM AND THEY SHOULD INVESTIGATE TO EXTEND THEIR RECALL TO INCLUDE THIS AND OTHER VEHICLES. I WILL BRING THE VEHICLE TO A JEEP DEALER. *TR”

“ORIGINALLY HAVING ISSUES SLOWING DOWN GOING AROUND CORNERS AND UP A STEEP INCLINE. FELT LIKE VEHICLE WAS STAYING IN HIGHER GEAR, YOU COULD DOWN SHIFT IT MANUALLY. AT THAT TIME THERE WERE NO CODES PRESENT IN THE SYSTEM. THEN LAST YEAR IN AUGUST 2011 WE DID A CROSS COUNTY TRIP (7000 MILES) VEHICLE WOULD STALL AT BOTH LOW SPEED AND HIGH SPEEDS, NOT EVERY DAY. SOMETIMES VEHICLE WOULD RESTART ITSELF AND OTHERS THE KEY HAD TO BE REMOVED AND REINSERTED, BUT MOST TIMES NOT. THE WEATHER DID NOT SEEM TO BE A FACTOR. UPON RETURN VEHICLE HAD APPROX 45,000 MILES, CODES RETREIVED FROM VEHICLE WERE MULTIPLE. ACTIVE CODES: B2105, C121C PENDING CODE: P0524 STORED CODES P0129, P0688, P0884. AT 35,000 MILES NEW OEM SPARK PLUGS AND WATER PUMP (DUE TO COOLANT LEAK) WITH NEW ANTIFREEZE. VEHICLE IS SERVICED REGULARLY EVERY 3,000 MILES SINCE NEW. SINCE 45,000 MILES ALL RELATED CIRCUITS AND COMPONENTS HAVE BEEN INSPECTED AND CHECKED FOR PROPER OPERATION. NEW CRANK SENSOR AND ELECTRICAL IGNITION SWITCH. CODE B2105 KEEPS RECURRING EVEN WITHOUT STALL. ALL WIRING CONNECTIONS AND GROUNDS HAVE BEEN CLEANED AND CHECKED, NEW BATTERY AT 36,000. HAD VEHICLE TO DEALER AND THEY SAID THEY MAY NOT…”

“MY VEHICLE STALLS WHILE DRIVING. IT HAPPENS WHILE AT IDLE AT A STOP LIGHT, AND IT HAPPENS WHILE AT SPEED. IT HASN'T OCCURRED YET AT SPEEDS ABOVE 45 MPH. EVERYTIME IT STALLS, I GET A OIL PRESSURE WARNING LIGHT. I OCCASIONALLY RECEIVE A ELECTRONIC THROTTLE WARNING LIGHT AS WELL. I ALSO OCCASIONALLY RECEIVE A ELECTRONIC STABILITY PROGRAM (ESP)/TRACTION CONTROL SYSTEM (TCS) INDICATOR LIGHT WHEN MY POWER STEERING CUTS OFF DUE TO THE ENGINE STALL. THE PROBLEM ALWAYS CORRECTS ITSELF UPON SHUTTING THE KEY OFF, AND RESTARTING THE VEHICLE. I HAVE HAD IT TO THE DEALERSHIP, AND THEY HAVEN'T BEEN ABLE TO DIAGNOSE NOR RECREATE THE PROBLEM. FYI, I RECENTLY HAD MY 5 YEAR POWERTRAIN INSPECTION DONE BY THE CHRYSLER DEALERSHIP, AND MY JEEP PASSED WITH NO NOTED ISSUES. I HAVE INCLUDED A LINK TO A WEBSITE THAT SHOWS MANY OTHER PEOPLE HAVING SIMILAR PROBLEMS WITH THIS VEHICLE. THIS VEHICLE IS A SAFETY HAZARD, AND IT NEEDS TO BE RECALLED.

“ENGINE STALLING DURING DECELERATION DUE TO OEM SPARK PLUGS THUS NO POWER STEERING OR POWER BRAKES WHEN IT IS NEEDED THE MOST. CHAMPION SPARK PLUGS HAS 2 DIFFERENT SPARK PLUGS WITH SAME PART NUMBER RE14MCC4. THIS IS THE CHRYSLER OEM SUPPLIER ANS PART NUMBER FOR HEMI ENGINE SPARK PLUGS THROUGH 2007. ONE OF THE TWO SPARK PLUGS IS INCOMPATIBLE WITH THE HEMI ENGINE AND LEADS TO STALLING WHILE DECELERATING. THE CONSUMER HAS NO INFORMATION ON WHICH ONE TO USE. NATIONAL AUTOMOTIVE PARTS DISTRIBUTORS HAVE NOT BEEN MADE AWARE OF THE DIFFERENCE. CHRYSLER HAS AN INTERNAL MEMO ("STAR CASE") THAT DOCUMENTS THE ISSUE BUT HAS NOT RELEASED IT TO THE PUBLIC. I WAS SHOWN THE MEMO BUT WAS NOT ALLOWED TO HAVE A COPY. NO TSBS EXISTS. NO RECALL EITHER. NHTSA TOLD ME THEY DO NOT HANDLE THIS. THEY ADVISED ME TO CONTACT THE FTC. THE FTC TOOK MY COMPLAINT BUT REFERRED ME TO THE DOT AS THEY WERE CONCERNED FOR CONSUMER SAFETY. I HAVE SIDE BY SIDE PICTURES OF THE 2 SPARK PLUGS WITH THE SAME PART NUMBER AND WOULD BE WILLING TO SUPPLY THEM. I ALSO HAVE ONE OF EACH PLUG IN MY POSSESSION. THERE IS VISUAL DIFFERENCES. THIS ISSUE OCCURRED IN A 2007 JEEP GRAND CHEROKEE WITH THE HEMI ENGINE. IT…”

“I WRITE THIS ONLY BECAUSE I JUST EXPERIENCE MY FOURTH MECHANICAL BREAKDOWN IN THREE YEARS. IN DECEMBER 2009, I EXPERIENCED THE FIRST BREAKDOWN IN WHAT HAS BECOME A STRING OF MALFUNCTIONS. THE TRANSMISSION ON MY 2007 GRAND CHEROKEE LAREDO GAVE OUT AT ABOUT 40,000 MILES. WHEN TRYING TO START THE VEHICLE, I GOT A 'TRANSMISSION OVERHEAT' MESSAGE ON THE DASH DISPLAY ALONG WITH THE ENGINE MALFUNCTION INDICATOR. I TOOK IT TO THE DEALERSHIP WHERE I PURCHASED IT AND IT TOOK NEARLY A MONTH FOR THE REPAIR SHOP TO LOCATE, RECEIVE AND INSTALL THE NECESSARY PARTS. APPARENTLY SUPPLY AND DEMAND HAD SOMETHING TO DO WITH IT, INDICATING TO ME THAT THIS WAS AN ISSUE NATIONWIDE. A MONTH LATER, ANOTHER MALFUNCTION, THIS TIME, THE ELECTRONIC SHIFT MODULE (ESM) HAD DIED. JUST OVER A YEAR LATER, THE SAME COMPONENT (ESM) DIED AGAIN (OF COURSE JUST OUT OF WARRANTY), THIS TIME WHILE I WAS DRIVING ALONG RT. 50 OUTSIDE OF DC. NOW, LESS THAN SIX MONTHS LATER, WITH LESS THAN 40,000 ON THE ALREADY REPLACED TRANSMISSION, MY TRANSMISSION HAS BLOWN AGAIN - SAME 'TRANSMISSION OVERHEAT' MESSAGE, SAME ENGINE MALFUNCTION LIGHT, SAME UNDRIVABILITY. CLEARLY FROM SEEING THE COMMENTS ON THIS FORUM AS…”
