2009 Jeep Grand Cherokee

TWICE WITHIN THE PAST MONTH, MY 2009 JEEP GRAND CHEROKEE WITH APPROXIMATELY 85,000 MILES HAS STALLED ON ME WHILE DRIVING. BOTH TIMES I TOOK IT TO A GARAGE; THE SECOND TIME I TOOK IT TO A JEEP DEALER/SERVICE CENTER. NO CODES WERE THROWN EITHER TIME AND NEITHER SERVICE PERSON WAS ABLE TO DUPLICATE THE PROBLEM. IT MAY BE A COINCIDENCE, BUT BOTH TIMES THIS HAPPENED, I HAD FILLED MY TANK WITH GAS THAT DAY. ON BOTH INSTANCES, I WAS ABLE TO PUT THE CAR IN PARK AND RESTART THE CAR WITH NO ISSUES. ADDITIONALLY, FOR THE PAST FEW MONTHS, THE CAR OFTEN DOES NOT START ON THE FIRST TRY. IT WILL START WITH NO PROBLEMS ON THE SECOND ATTEMPT. DEALERSHIP HAS REPLACED THE WIN MODULE; THIS DID NOT SEEM TO HELP. THE THROTTLE BOTTLE WAS ALSO REPLACED IN CASE THAT WAS CAUSING THE STALLING; THAT DID NOT HELP EITHER.I NOW FEEL AS IF I AM RISKING MY LIFE AND MY KIDS' LIVES EVERY TIME I STEP INTO THE CAR AND TAKE IT ON THE HIGHWAY. IF THIS STALLING ISSUE HAPPENS ON A HIGHWAY, WE COULD BE KILLED IN AN INSTANT. VERY DANGEROUS AND THE SERVICE PEOPLE DON'T SEEM ALL THAT CONCERNED...THEY CAN'T PINPOINT THE ISSUE SO THEY CHARGE ME $100+ AND SEND ME ON MY WAY. *TR

AFTER RECEIVING N23 SAFETY RECALL "FIX" LOST USE OF 4WD LOW RANGE (WHICH ALSO ALLEGEDLY COMPROMISES CLUTCH PACKS CONTROLLING HIGH-RANGE 4WD SYSTEM TORQUE/POWER DISTRIBUTION). JEEP DEALER DIAGNOSED AND REPLACED TRANSFER CASE ACTUATOR. "FIX" LASTED 1MO. RETURNED TO DEALER; TROUBLE CODES CLEARED. PROBLEM RETURNED IN LESS THAN 24H. THIS IS THE CORRESPONDENCE SENT TO JEEP: ...I BELIEVE THIS TO BE A SOFTWARE ISSUE, AND MY REASONS ARE THIS: 1) THE ACTUATOR WORKS AS DESIGNED AFTER ALL CODES ARE RESET/CLEARED (THOUGH THE DURATION FOR WHICH THIS WORKS IS NOT CONSISTENT) 2) PULLING A FUSE FOR THE FDCM IS THE SAME AS "RESETTING/CLEARING" THE TROUBLE CODE - THIS DOES NOT POINT TO THE HARDWARE AS THE PROBLEM. 3) IF I UNDERSTAND THE SYSTEM CORRECTLY, LOSING FUNCTIONALITY OF THIS PORTION OF THE SYSTEM, WITH MY QUADRA-DRIVE II, CAUSES A SAFETY SIDE-EFFECT OF COMPROMISED TRACTION CONTROL SINCE THE CLUTCH PACKS IN THE TRANSFER CASE FOR AWD FUNCTION MALFUNCTION WHEN THE TROUBLE CODE IS LODGED. THIS VEHICLE OPERATED NORMALLY (ALBEIT WITH RISK OF A ROLL-AWAY WHEN REMOTE START IS USED WITHOUT THE PARKING BRAKE) PRIOR TO THE N23 RECALL. FOR IT TO ONLY EXHIBIT ISSUES AFTER THE RECALL, THEN CONTINUE TO EXHIBIT THEM AFTER REPLACING THE TRANSFER CASE ACTUATOR MAKES THE SOFTWARE UPDATE HIGHLY SUSPECT AS A CONTRIBUTING FACTOR, IF NOT A ROOT CAUSE. I BELIEVE THIS ISSUE (IF IT IN FACT COMPROMISES THE TRACTION CONTROL SYSTEM) IS A SERIOUS SAFETY CONCERN, AND BELIEVE THAT IF FCA CANNOT FIND A SOLUTION QUICKLY, I WILL TAKE ACTION. I USE MY JEEP DAILY TO COMMUTE ON PUBLIC ROADS, AND CANNOT CONTINUE TO AFFORD TO HAVE IT OUT OF SERVICE OR AT RISK OF INCREASED SAFETY HAZARD. THANK YOU IN ADVANCE FOR YOUR ASSISTANCE... THIS IS UNACCEPTABLE AND THERE ARE MANY OTHERS WITH THE SAME ISSUE. A RECALL SHOULDN'T REDUCE FUNCTIONALITY OF THE VEHICLE. PERIOD. *TR

VEHICLE IS EQUIPPED WITH THE 5.7L HEMI ENGINE. UPON STARTING THE VEHICLE, IDLE WAS VERY ROUGH, AND VEHICLE SHUT OFF. CHECK ENGINE LIGHT CAME ON. IMMEDIATELY, ESTARTED THE VEHICLE AND EXPERIENCED NO FURTHER ISSUE, HOWEVER CEL STAYED ILLUMINATED. AFTER A COUPLE QUICK TRIPS AROUND THE NEIGHBORHOOD THE CEL TURNED OFF AND THE VEHICLE RAN NORMAL. A COUPLE DAYS LATER WHILE ACCELERATING FROM A STOP AT A TRAFFIC LIGHT THE VEHICLE STALLED, AND THE CEL CAME BACK ON. RESTARTED THE VEHICLE, AND IT RAN NORMAL THE REMAINDER OF THE DAY, CEL STAYED LIT FOR A WHILE, BUT EVENTUALLY TURNED OFF. APPROXIMATELY 4-5 DAYS LATER, THE VEHICLE STALLED AGAIN WHILE WAITING AT A TRAFFIC LIGHT. CEL CAME ON. I RESTARTED THE VEHICLE, AND DROVE IT HOME. I PULLED THE CODE FOR THE CEL USING MY ODB READER, AND IT WAS A P0129 (BAROMETRIC PRESSURE OUT OF RANGE). I TOOK THE VEHICLE TO THE DEALERSHIP, BY THE TIME I GOT THERE THE CEL WAS NO LONGER LIT. THE DEALERSHIP WAS ABLE TO FIND THE STORED CODE, BUT SAID THAT THEY COULD NOT REPRODUCE THE PROBLEM. THEY CHECKED THE MAP SENSOR, AND SAID IT WAS FINE, BUT REFUSED TO TAKE ANY FURTHER ACTION SINCE IT WAS NOT EXHIBITING ANY ISSUES ASIDE FROM THE STORED CODE THEY FOUND. SEARCHING THE INTERNET, I'VE FOUND MULTIPLE PEOPLE WITH THE SAME ISSUE ON THIS SERIES GRAND CHEROKEE, MANY, AS I, WHO ARE FRUSTRATED WITH NO RESOLUTION FROM THE MANUFACTURER. DEALER HAS ADVISED ME TO COME PICK UP MY VEHICLE, WITHOUT ANY FIX OR EXPLANATION AS TO WHAT IS CAUSING THIS. THIS IS A SAFETY ISSUE AS THE VEHICLE CAN AND WILL STALL IN TRAFFIC CREATING A POTENTIAL FOR A TRAFFIC COLLISION OR LOSS OF CONTROL. *TR
