2007 JEEP GRAND CHEROKEE Complaints

I PURCHASED 07 JEEP 10/20/2012 SHORTLY AFTER IT STALLED IN CAR WASH ABOUT A WEEK LATER IT STALLED AGAIN. THE PROBLEM SOON BEGAN TO STALL ON INTERSTATE AND RECOVERS AT HIGHER SPEEDS. AS TIME PASSES THE PROBLEM IS HAPPENING AT LEAST 8 TIMES A WEEK MOSTLY WHILE IDLING OR COASTING. *TR

I WAS DRIVING DOWN THE ROAD, ONLY GOING AROUND 15 MPH, WHEN MY P R N D ALL LIT UP AND I WAS UNABLE TO DRIVE. I STOPPED AND PUT IT IN PARK AND TRIED AGAIN AND IT RAN FINE. THIS HAPPENED ON TWO OTHER OCCASIONS. I WAS GETTING READY TO LEAVE AND PUT MY VEHICLE IN DRIVE AND IT JERKED FORWARD. I'M VERY DISAPPOINTED THAT I HAVE TO REPLACE THE ELECTRONIC MONITORING SYSTEM AT SUCH A LOW MILEAGE, THE COST FOR THIS IS CLOSE TO $400 AND THAT IS NOT PRICING LABOR AND NOT TO MENTION DANGEROUS FOR THIS TO HAPPEN WHILE YOU ARE DRIVING. *TR

I BOUGHT MY 2007 JEEP GRAND CHEROKEE OVERLAND IN JUNE OF 2011 WITH 52095 MILES ON IT. IN MARCH OF 2012, I EXPERIENCED THE FIRST OF MANY STALLS HAPPEN TO THE JEEP WITH 60,980 MILES ON IT. IT HAS RANDOM, UNPREDICTABLE STALL OUTS THAT HAPPENED THROUGH OUT THE YEAR. IT SEEMS TO STALL WHEN ACCELERATING HOWEVER NOT ALL THE TIME. IT'S STALLED WHILE DRIVING ON THE HIGHWAY (MASS PIKE OR RT. 9) AND ON SIDE ROADS. I HAVE NOT OBSERVED ANY PRECURSORS TO THE STALLING. WHEN IT STALLS, IT BUCKS AND THEN THE JEEP DOES NOT ACCELERATE HOWEVER THE LIGHTS COME ON, JUST LIKE WHAT HAPPENS WHEN A MANUAL VEHICLE IS STALLED. THESE TYPES OF STALL OUTS I EXPERIENCE DO NOT HAPPEN ALL THE TIME. WHAT HAPPENS SOMETIMES IS THE JEEP WILL BUCK, LIKE IT'S GOING TO STALL, BUT IT DOESN'T AFTER SLAMMING ON THE ACCELERATOR. AFTER A STALL OUT, I AM ABLE TO RESTART THE JEEP AFTER A MINUTE OR TWO. THE ENGINE LIGHT HAS NEVER COME ON, JUST THE OIL LIGHT. THIS JEEP HAS HAD THE IGNITION CONNECTOR AND SOFTWARE REPLACED TWICE IN OVER A PERIOD OF TWO YEARS. IT'S BEEN REPLACED BECAUSE OF A STORED CODE: FCMCGW B2185 . THERE ARE TWO OTHER CODES STORED IN THE COMPUTER: PCM P0884 AND ABS C12K. I HAVE TAKEN THE JEEP TO DAN'S JEEP IN WESTBOROUGH, MA SINCE THE FIRST STALL OUT TO THE PRESENT. THE RECENT STALL OUT WAS FRIDAY, JANUARY 11TH. THIS STALL OUT WAS A LITTLE DIFFERENT BECAUSE "PROGRAMMING ASSESS" (SOMETHING LIKE THAT) APPEARED ON THE DASH WITH A BLINKING RED LIGHT. EVERYTIME I BRING THE JEEP TO DAN'S, THEY GIVE ME THE SAME RESPONSE TO THE PROBLEM...THEY DON'T' KNOW WHY THIS IS HAPPENING AND I CAN START REPLACING PARTS TO SEE IF IT CORRECTS THE PROBLEM. I DO NOT HAVE THE FINANCES TO JUST KEEP REPLACES PARTS TO SEE IF IT'LL CORRECT THIS SERIOUS AND UNSAFE PROBLEM WITH THE JEEP AND CHRYSLER HAS NOT REPORTED HOW TO FIX THIS OR MADE THE STEP FORWARD TO FIX IT. *TR

VEHICLE STALL OUT AT VARIOUS SPEEDS, OR WHEN IDLING STATIONARY. COMES ON WITHOUT WARNING. SEEMS THESE STALLING PROBLEMS ARE COMMON WITH 5.7 HEMI JEEP GRAND CHEROKEES, EVEN ACCORDING TO THE DEALER. THIS IS A SERIOUS SAFETY HAZARD AS POWER STEERING AND BRAKES ARE LOST DURING A STALL. AN INOPERATIVE VEHICLE IN A TRAFFIC LANE COULD SUFFER A REAR-END COLLISION FROM THIS CONDITION. PLEASE HELP BY ORDERING A RECALL FROM CHRYSLER COMPANY TO REMEDY THE PROBLEM. NOTHING SEEMS TO REMEDY THE SITUATION AND IT KEEPS OCCURRING. *TR

DRIVING DOWN ROAD AND ENGINE STALLED. LOSS OF POWER STEERING AND POWER BRAKES. PUT CAR IN PARK AND THE CAR STILL MOVED WOULDN'T RESTART HAD TO SWITCH IGNITION OFF AND TAKE KEY OUT OF IGNITION BEFORE ENGINE WOULD START. STALLS AT RANDOM WITHOUT ANY ENGINE MALFUNCTION LAMPS. HAZARD TO BE DRIVING ON ROAD. PROBLEM STILL UNKNOWN AND VEHICLE IS OUT OF EXTENDED WARRANTY. *TR

PURCHASED 2007 JEEP GRAND CHEROKEE OVERLAND 5.7 HEMI JULY 31, 2007. DECEMBER 1, 2010 MY WIFE WAS TRAVELING ON AN INTERSTATE AT 65 MPH WHEN THE ENGINE SUDDENLY SHUT DOWN. SHE MANAGED TO PULL THE CAR OFF THE ROAD, STARTED THE ENGINE AND DROVE HOME WITHOUT ANY MORE ISSUES. DEALERSHIP TECHNICIAN DISCOVERED P0884 CODE FROM THE PCM. HE COULD NOT FIND ANY PROBLEMS. CAR CONTINUED TO STALL NUMEROUS TIMES AT HIGH SPEED AND SOMETIMES WHILE STOPPED AT A STOP SIGN OR RED LIGHT. THIS PROBLEM STARTED SHORTLY AFTER THE ENGINE SPARK PLUGS WERE CHANGED. AFTER NUMEROUS PARTS WERE CHANGED AT THE DEALERSHIP, WITH NO RESULTS, THE TECHNICIAN CONTACTED AN ENGINEER FROM THE CHRYSLER COMPANY. DURING AN ON SITE VISIT THE ENGINEER SUSPECTED THERE WAS AN ISSUE WITH THE UPPER ENGINE HARNESS RECEIVING AN ELECTRICAL INDUCTION FROM THE ENGINE COILS CAUSING THE PCM TO SHUT THE ENGINE DOWN. THE TECHNICIAN INSTALLED FOIL AROUND THE HARNESS AND WIRE TIED THE HARNESS UP OFF THE CRADLES THEY LAY IN. ENGINE PERFORMED NORMAL WITH NO SHUT DOWNS FOR SEVERAL MONTHS. DECISION WAS MADE TO CHANGE THE UPPER ENGINE HARNESS. SINCE THE HARNESS WAS CHANGED MY JEEP HAS STALLED OUT FOUR MORE TIMES. THE MOST RECENT STALL OCCURRED THE LAST WEEK OF DECEMBER 2012. THIS IS AN EXTREMELY DANGEROUS SITUATION TO BE TRAVELING AT INTERSTATE SPEED LIMITS AND YOUR CAR STALLS. CHRYSLER PLACES DRIVERS IN A SITUATION WITH A VEHICLE THAT IS UNCONTROLLABLE WHILE TRAVELING ON AN INTERSTATE WITH CARS BEHIND YOU. I STARTED AN ON LINE THREAD IN JEEP FORUM.COM CONCERNING THIS ISSUE. HTTP://WWW.JEEPFORUM.COM/FORUM/F67/2007-JEEP-GRAND-CHEROKEE-OVERLAND-STALLING-PROBLEM-1147825/. THERE ARE NUMEROUS OTHER FOLKS HAVING THIS PROBLEM IN THE USA, CANADA, AND HAWAII. I THINK THAT AN INVESTIGATION SHOULD BE PERFORMED TO DISCOVER WHAT IS CAUSING THIS ISSUE AND COME UP WITH A POSITIVE REPAIR FOR CUSTOMERS THAT ARE HAVING THIS PROBLEM. *TR

BEGAN STALLING WHEN STOPPED OR COMING TO A STOP WITH FOOT OFF THE ACCELERATOR. ENGINE WOULD START UP JUST BY RESTARTING THE JEEPS. MONTHS LATER SOMETIMES YOU WOULD HAVE TO TURN THE KEY TO OFF BEFORE IT WOULD START,. ON AVERAGE IT WOULD STALL ONCE EVERY 7 TO 10 DAYS. NO CODES, STORED OR PENDING DURING THIS JOURNEY. REPLACED THE CAM SENSOR. CHECK HOSES FOR VACUUM LEAK, FOUND NONE. REPLACED THE ASD RELAY. CHANGED FROM PREMIUM TO MID GRADE. CHANGED TO REGULAR GRADE. CHECKED AIR FILTER AND CLEANED THROTTLE BODY WITH STP CLEANER. ADDED FUEL SYSTEM CLEANER TO FUEL TANK. CHECKED ALL OF THE ELECTRONIC CONNECTORS, NONE LOOSE OR DAMAGED. CHECKED TRANSMISSION FLUID LEVEL WAS FINE. REPLACED MAP SENSOR AND POSITION CRANK SENSOR. REPLACE EGR VALVE CHANGED OIL AND FILTER FOR THE FIRST TIME SINCE I PURCHASED THE JEEP. USED SAE 5W30. WITH 79,000 MILES ON THE HEMI I REPLACED ALL SIXTEEN CHAMPION 570 WITH NEW CHAMPION 570. SPRAYED EACH OF THE 16 BOOTS WITH ELECTRONIC CLEANER VERIFIED THE PLUG GAP AND TORQUED THE PLUGS. SPRAYED VAST AMOUNT OF STP THROTTLE BODY CLEANER IN THE TB AND STP FUEL SYSTEM CLEANER IN THE GAS TANK. STILL STALLING. *TR

DRIVING DOWN ROAD AND ENGINE STALLED. LOSS OF POWER STEERING AND POWER BRAKES. CAUSED CAR BEHIND ME TO SLAM ON BRAKES TO AVOID GETTING HIT. PUT IN NEUTRAL AND TRIED TO START. HAD TO SWITCH IGNITION OFF BEFORE ENGINE WOULD START. STALLS AT RANDOM WITHOUT ANY ENGINE MALFUNCTION LAMPS. HAZARD TO BE DRIVING ON ROAD. PROBLEM STILL UNKNOWN AND VEHICLE IS OUT OF EXTENDED WARRANTY BY FIVE THOUSAND MILES. *TR

WHILE DRIVING ON THE INTERSTATE AT 65 MPH, THE VEHICLE'S ENGINE STALLED. I HAD TO PUT THE VEHICLE IN NEUTRAL, TURN THE IGNITION OFF AN BACK ON TO RESTART IT. THIS FIRST HAPPENED JUST AFTER THE 30 DAY WARRANTY WAS OVER, AS I BOUGHT THE VEHICLE USED IN MAY OF 2012. SINCE THAT TIME, THE VEHICLE HAS STALLED AT HIGHWAY SPEEDS OR WHEN SLOWING DOWN FOR A STOP ON DOZENS IF NOT HUNDREDS OF OCCASIONS. THE SPARK PLUGS, EGR VALVE, IGNITION COIL, PCV VALVE AND MAP SENSOR HAVE BEEN CHANGED TO NO EFFECT. THERE ARE NO MEANINGFUL DIAGNOSTIC CODES STORED IN THE OBD-II SYSTEM. I FEEL THIS CONDITION IS VERY DANGEROUS, AS I NEVER KNOW WHEN THE VEHICLE WILL STALL, CAUSING A LOSS OF POWER STEERING AND BRAKES, AND THE ABILITY TO ACCELERATE OUT OF HARM'S WAY. IT IS MY UNDERSTANDING THAT MANY OF THESE SAME VEHICLES WITH THE SAME ENGINE ARE HAVING SIMILAR ISSUES. I CAN NO LONGER LET MY WIFE OR TEENAGE SON DRIVE THE VEHICLE BECAUSE OF THIS CONDITION. *TR

WHILE DRIVING THE VEHICLE THE ENGINE WILL RANDOMLY SHUT OFF (STALL), THIS OCCURS AT ANY SPEED AND ANY DRIVING CONDITION, OCCASIONALLY IT WILL BE VERY DIFFICULT TO RESTART, TAKING MULTIPLE TRIES. THIS IS EXTREMELY DANGEROUS ESPECIALLY WHEN TURNING ACROSS THE OPPOSING LANE. THE STALLING HAPPENS FREQUENTLY AT TIMES, AS MUCH AS 3 TO 4 TIMES A DAY. *TR
