2007 Jeep Grand Cherokee

UPON ACCELERATION FROM STOP VEHICLE WILL HESITATE AND LOSE POWER. THIS CONSTITUTES A HAZARD TO VEHICLE AND ANY APPROACHING VEHICLES DURING A TURN. INSPECTION INDICATES THAT TRANSMISSION ELECTRONIC CONTROL MODULE IS AT FAULT ALONG WITH A POSSIBLE TRANSMISSION SENSOR FAILURE. THE CHECK ENGINE LIGHT WILL COME ON. BOTH OF THESE CONDITIONS ( POWER AND CHECK ENGINE ) ARE INTERMITTENT, INDICATING THAT THE MODULE IS FAULTY. THERE HAVE BEEN MANY COMPLAINTS ABOUT THE TRANSMISSION ECM ON THESE VEHICLES. THE OTHER COMPLAINTS HAVE VARYING SYMPTOMS BUT ALL GO BACK TO THE TRANSMISSION ECM. THESE UNIT SHOULD BE RECALLED AND REPAIRED OR REPLACED AT MANUFACTURERS COST. THIS PROBLEM EXISTS IN MANY DIFFERENT MODELS AND YEARS OF VEHICLES, BUT ALWAYS GO BACK TO THIS ECM UNIT. AFTER INVESTIGATING THIS PROBLEM I DON'T FEEL THAT THE CONSUMER IS AT FAULT OR CAUSING THIS TO OCCUR. CHRYSLER MODULES ARE AND HAVE BEEN FAULTY IN THE PAST. ANECDOTAL EVIDENCE SAYS THAT OTHER MODULES IN CHRYSLER VEHICLES HAVE HAD PROBLEMS TOO. PLEASE INVESTIGATE THE CHRYSLER TRANSMISSION ECM'S AND HAVE THEM RECALLED. *TR

WHILE I WAS DRIVING HOME LAST NIGHT 12/16/11 WITH MY FIANCEE WE STOPPED AT A TRAFFIC LIGHT, AND WHEN THE LIGHT TURNED GREEN THE JEEP STARTED BACK UP FINE ALL EXCEPT IT COULDN'T GO FASTER THAN 20 MILES PER HOUR. SO I PUT MY FLASHERS ON AND THE TRAFFIC BEHIND ME WENT AROUND US, THEN IT WORKED ITSELF OUT, BUT DID IT AGAIN WHEN I CAME TO ANOTHER TRAFFIC LIGHT. BUT THIS TIME I WAS ABLE TO USE MY MANUAL SHIFT TO HELP IT. NO WARNING LIGHTS CAME ON. AND I JUST PURCHASED THIS JEEP 2 DAYS AGO. I WOULD LIKE TO GET THIS SAFETY ISSUE FIXED SINCE I HAVE SEEN THAT THIS IS A DANGEROUS AND COMMON PROBLEM WITH THE OTHER 2007 JEEP GRAND CHEROKEES. I AM ALSO A FIREFIGHTER AND I DEPEND ON THIS JEEP TO GET ME TO FIRE SCENES AND OTHER EMERGENCY SCENES, AND I DON'T WANT TO BE IN AN EMERGENCY SCENE INVOLVING ME DUE TO THE SAFETY ISSUES THIS JEEP IS HAVING. CAN SOMEONE PLEASE DO A RECALL AND HAVE THIS ISSUE FIXED. *TR

I WAS DRIVING APPROXIMATELY 40 MPH IN THE FAST LANE OF A MAIN TWO-LANE RESIDENTIAL ROADWAY WHEN THE VEHICLE SUDDENLY JERKED VIOLENTLY FORWARD THROWING ME INTO THE STEERING WHEEL AND THEN ALL ACCELERATION AND SPEED STOPPED. THE STEERING WHEEL BECAME ABNORMALLY STIFF AND DIFFICULT TO TURN HOWEVER I WAS ABLE TO GUIDE THE COMPLETELY STALLED AND DECELERATING VEHICLE TO THE SLOW LANE AND PULL-OFF ON THE SIDE OF THE ROAD (WITH NO SIDE LANE) WITH HAZARDS FLASHING AND TRAFFIC PASSING. THIS WAS AN INHERENTLY DANGEROUS CONDITION AS THE FLOW OF TRAFFIC WAS GOING APPROXIMATELY 35 - 40 IN THE FAST LANE AT WHICH TIME I COMPLETELY LOST POWER AND HAD LIMITED STEERING (MORE LIKE COASTING) ABILITY. I WAS ABLE TO TURN THE ENGINE COMPLETELY OFF AND RESTART, HOWEVER THE NEXT DAY UNDER SIMILAR CONDITIONS OF NORMAL DRIVING CONDITIONS THE VEHICLE JERKED AND STALLED AGAIN, AND RESTARTED AFTER A COMPLETE SHUTDOWN. THIS VEHICLE ON THE THIRD DAY POST THE FIRST INCIDENT FAILED TO RESTART AFTER DRIVING TO A LOCAL SHOPPING DESTINATION AND TURNING THE CAR OFF TO PARK. I LEFT THE VEHICLE AT THE LOCATION FOR APPROXIMATELY 4 TO 5 HOURS AND RETRIEVED THE VEHICLE UPON WHICH IT STARTED WITH A DOCUMENTED CALL INTO ROAD SIDE ASSISTANCE PROGRAM FROM JEEP. THE NEXT DAY (MONDAY) I DROVE TO AN AUTHORIZED DEALER UPON WHICH THEY STATED THE FAILURE WAS THE ELECTRONIC SHIFT MODULE (ESM) [(NOT TO BE CONFUSED WITH THE ELECTRONIC STABILITY CONTROL (ESC)] WHICH CONTROLS THE ELECTRONIC SIGNALS FROM THE COMPUTER TO THE TRANSMISSION AT A PERSONAL COST OF $820. I BELIEVE THIS REPRESENTS A KNOWN DEFECT AS CURRENTLY 55 OUT OF THE 133 COMPLAINTS LISTED HERE ARE DESCRIBING A SIMILAR SERIES OF EVENTS AND ROOT CAUSE, AND WOULD BE WILLING TO BE INVOLVED IN A CLASS ACTION LAW SUIT AGAINST JEEP AS LIFE, LIMB AND PROPERTY ARE AT STAKE. *TR

WHEN YOU SHIFT FROM PARK THE PRDNL WILL HAVE A BOX AROUND EACH OF THE LETTERS. WHEN BACKING UP IT SLAMS INTO REVERSE AND THEN SLAMS INTO DRIVE AND THE VEHICLE WILL ONLY GO 20 MPH NO MATTER HOW MUCH YOU STEP ON THE GAS. THIS HAS NOW HAPPENED 5 TIMES AND THE ONLY WAY IT GOES BACK TO NORMAL IS TO SHUT OFF THE VEHICLE AND START IT BACK UP. I HAVE NOW SEEN NUMEROUS BLOGS WHERE THIS HAPPENS AT HIGHWAY SPEEDS, IN THE MIDDLE OF INTERSECTIONS AND IS SO DANGEROUS TO DRIVE CAUSE YOU NEVER KNOW WHEN IT IS GOING TO HAPPEN. FROM WHAT I HAVE READ IT LOOKS LIKE YOU HAVE TO REPLACE THE ELECTRONIC CONTROL MODULE AT A COST OF ALMOST $800 TO JUST HAVE IT GO OUT AGAIN LATER AND HAVE THE SAME PROBLEM AGAIN. THIS IS VERY DANGEROUS AND SCARY! *TR

WHILE DRIVING THE VEHICLE, HAD A SUDDEN LOSE OF ABILITY TO ACCELERATE, NO THROTTLE RESPONSE, NO RPMS ON THE TACH, AND EVERY GEAR INDICATOR WAS ILLUMINATED AS IF IN ALL GEARS AT THE SAME TIME (PARK, REVERSE, NEUTRAL, DRIVE). DEALERSHIP SAYS ITS PART # 52124137AC THAT NEEDS TO BE REPLACED, AND IS NOT COVERED UNDER ANY POWER TRAIN WARRANTY, AT A COST OF $817.00. THIS PROBLEM HAPPENED 4 TIMES BEFORE I WAS ABLE TO GET IT IN TO THE LOCAL DEALERSHIP, NEVER ON THE HIGHWAY, IF IT HAD HAPPENED ON THE HIGHWAY, IM SURE I WOULD HAVE BEEN TAKING A CHANCE WITH MY LIFE. *TR

OWNED THE 07 JEEP FOR 5 MONTHS. VEHICLE HAS BEEN SERVICED FOR 2 DIFFERENT INCIDENTS. THE 1ST INCIDENT(ACTUALLY HAPPENED SEVERAL TIMES) IS WHEN THE VEHICLE WOULD NOT SHIFT DURING ACCELERATION AND IT WOULD FORCE ME TO THE SIDE OF THE ROAD WHERE I WOULD HAVE TO TURN THE VEHICLE ON AND OFF UNTIL IT WOULD RUN CORRECTLY. WAS TOLD BY DEALERSHIP SERVICE THAT IT WAS A TRANSMISSION SENSOR,HAD THE PART REPLACED-NOT COVERED BY WARRANTY. LESS THEN 3 WEEKS LATER, 2ND INCIDENT OCCURRED WHEN I WAS DRIVING 55MPH DOWN THE INTERSTATE WHILE ACCELERATING TO GET OVER TO AN EXIT, THE VEHICLE THREW ITSELF BACK INTO 2ND GEAR AND I WAS FORCED TO GET OVER INTO THE EMERGENCY LANE SO AS NOT TO BE STRUCK BY ONCOMING TRAFFIC. THE JEEP HAD ALMOST COME TO A COMPLETE STOP IN TRAFFIC! CHECK ENGINE LIGHT CAME ON AND WENT OFF AFTER THAT. DEALERSHIP STATES THE GEAR RATIO AND VALVE COVER FORCED THE VEHICLE INTO 2ND GEAR. VERY DANGEROUS! *TR

MY JEEP HAS EXPERIENCED THREE ELECTRICAL FAILURES WHICH HAVE OCCURRED APPROXIMATELY 6 MONTHS APART. FOR SOME UNKNOWN REASON THE BATTERY DIED OVERNIGHT EACH TIME. THE SECOND TIME IT HAPPENED I PURCHASE A NEW BATTERY BUT SIX MONTHS LATER IT DRAINED TOO. I WAS ABLE TO SUCCESSFULLY JUMP-START THE VEHICLE AFTER EACH INCIDENT. TRANSMISSION----I HAVEN'T BEEN ABLE TO DOWN-SHIFT FROM DRIVE TO A LOWER GEAR. THIS PROBLEM BEGAN AT ABOUT 46000 MILES. I TOOK IT TO A REPAIR SHOP WHERE THEY DIAGNOSED THE PROBLEM AS DEFECTIVE SHIFTER CONTROL. BEFORE I HAD IT REPAIRED (EST. $1000) IT BEGAN FUNCTIONING NORMALLY, THAT IS, UNTIL TODAY. I LEFT A PARKING LOT AND MERGED INTO TRAFFIC. FORTUNATELY TRAFFIC WAS LIGHT BECAUSE I COULDN'T GET THE JEEP TO GO ANY FASTER THAN 28 MPH. IT SEEMED LIKE THE TRANSMISSION WAS STUCK IN FIRST. ALSO THE ENGINE LIGHT CAME ON. THIS IS A VERY SERIOUS SITUATION THAT SHOULD NOT BE IGNORED BY THE CHRYSLER CORP. OR THE NATIONAL HIGHWAY TRAFFIC SAFETY ADM.. *TT

TL* THE CONTACT OWNS A 2007 JEEP GRAND CHEROKEE. THE CONTACT STATED THE GEAR SHIFT MODULE CAUSED THE VEHICLE TO LUNGE FORWARD AND BACKWARDS. THE VEHICLE WOULD NOT ACCELERATE OVER 20 MPH. THERE WAS ALSO A WARNING LIGHT ILLUMINATED INDICATING THE GEAR SHIFT HAD FAILED. THE VEHICLE WAS TAKEN TO THE DEALER WHO REPLACED THE GEAR SHIFT MODULE. THE MANUFACTURER WAS NOTIFIED AND INFORMED HER TO FILE A COMPLAINT BUT OFFERED NO OTHER ASSISTANCE. THE FAILURE MILEAGE WAS 98,300.

ON OCT.5TH AS I WAS MERGING ONTO THE THRUWAY AT 55MPH THE TRUCK JUST STOPPED ACCELERATING IN RUSH HOUR TRAFFIC. I PUT ON MY FLASHERS AND COASTED TO THE SHOULDER JUST BARELY AVOIDING BEING REAR ENDED. THIS WAS THE SECOND TIME THIS HAS HAPPENED WITH THIS VEHICLE. YOU COULD PRESS THE GAS PEDAL AND THE RPM'S WOULD GO SKY HIGH BUT THE TRUCK WOULD NOT MOVE WHILE IN DRIVE. I TURNED THE TRUCK OFF,WAITED SEVERAL SECONDS,STARTED THE TRUCK AND IT MOVED IN DRIVE. I IMMEDIATELY CALLED THE DEALER AND HAVE A OCT.7TH SERVICE CALL.THIS WAS A NEAR DEATH SITUATION THE SECOND TIME DUE TO THE RUSH HOUR TRAFFIC. THIS VEHICLE HAS TROUBLE SHIFTING WHEN STARTED IN THE MORNING. AFTER LOOKING INTO THE MATTER THIS APPEARS TO BE A COMMON PROBLEM WITH THIS MODEL AND MAKE. IT APPEARS THE ELECTRONIC SHIFT MODULES NEED REPLACING.AFTER READING THE NUMEROUS SIMILAR COMPLAINTS I THOUGHT I WOULD FILE A COMPLAINT BEFORE SOMEONE GETS KILLED. *TR
