2009 Jeep Grand Cherokee Engine Problems

VEHICLE WILL LOSE POWER WHILE DRIVING. SOMETIMES WILL LOOSE POWER WHILE PULLING OUT. VERY DANGEROUS WHEN PULLING ONTO THE HIGHWAY. HAVE TO PULL TO SHOULDER TO AVOID BEING REAR ENDED.

UPPER RADIATOR HOSE ELBOW FAILED ALLOWING IMMEDIATE LOSS OF ALL COOLANT FLUID. THE BARB ON THE END OF THE PLASTIC ELBOW BROKE OFF ALLOWING THE HOSE TO SLIP OFF THE ELBOW. THIS OCCURRED WHILE DRIVING AND RESULTED IN IMMEDIATE CHECK ENGINE LIGHT AND OVERHEATING OF ENGINE. THE DRIVING WAS BEING DONE BY A FIRESTONE TECHNICIAN THAT WAS TEST DRIVING THE VEHICLE AFTER A FRONT END ALIGNMENT. BASED ON COMMENTS BY OTHER OWNERS OF THE SAME VEHICLE THIS IS A COMMON OCCURRENCE ( HTTP://WWW.CHEROKEESRT8.COM/FORUMS/SHOWTHREAD.PHP?T=50508).

WHEN THE RED LIGHT TURNED GREEN, I TRY TO PROCEED ACROSS THE INTERSECTION WHEN THE CAR JUST DIED. THE RADIO CONTINUED TO PLAY BUT I HAD NO POWER STEERING. I MANAGED TO PULL OVER AND TURN ON MY FLASHERS. MEANWHILE THE RADIO CONTINUED TO PLAY. I PUT THE CAR IN PARK AND TRY TO START THE CAR AGAIN AND IT DID INDEED START. IF I HAD BEEN DRIVING ON I75 GOING 70MPH AND THE CAR STALLED I WOULD BE IN HUGE TROUBLE. THE GOODYEAR MECHANIC COULD NOT FIND THE PROBLEM. *TR

THIS IS THE THIRD INCIDENT SINCE AUGUST OF THIS YEAR. LATEST INCIDENT OCCURRED TODAY, OCTOBER 14, 2014. IN EACH INCIDENT, THE ENGINE SUDDENLY GOES INTO A ROUGH IDLE AND EVENTUALLY STALLS WITH LOSS OF POWER. I HAVE BEEN ABLE TO STEER THE CAR OFF THE ROAD AND SWITCH BETWEEN OFF/START POSITIONS UNTIL THE VEHICLE STARTS. THE VEHICLE RUNS NORMALLY AFTER THESE INCIDENTS WITH NO "CHECK ENGINE" LIGHT DISPLAYED. REPORTED THE INCIDENT TO CHRYSLER AND THEY TOLD ME THIS YEAR JEEP WAS NOT IN SCOPE OF THEIR RECENTLY ANNOUNCED RECALL FOR THE SAME PROBLEM. *TR

ON TWO OCCASION MY CHECK ENGINE LIGHT CAME ON. BOTH TIMES THE THERMOSTAT GAGE KEPT GOING UP AND DOWN. ON BOTH OCCASION I TOOK THE VEHICLE TO HAVE IT CHECKED. ON THE SECOND OCCASION THAT THIS HAPPENED I WAS TOLD THAT A TECHNICAL SERVICE BULLETIN HAD BEEN ISSUED FOR THIS PROBLEM. (PULL CODE #P2181) I WAS ALSO TOLD THAT I HAD TO TAKE THE VEHICLE TO A DEALER TO HAVE IT TAKEN CARE OF. SINCE THIS IS A MANUFACTURING ISSUE I FELT THAT IT SHOULD BE TAKEN CARE AT NO COST TO ME BUT WAS INFORMED THAT I WOULD NEED TO IN FACT PAY FOR THIS UPDATE. (NOT ONLY DO I NEED TO PAY BUT I ALSO HAVE TO TAKE TIME OFF FROM WORK TO HAVE THIS DONE). *TR

WHILE DRIVING ON U.S. HIGHWAY 270 IN ARKANSAS THIS DATE, MY 2009 JEEP GRAND CHEROKEE EXPERIENCED SUDDEN UNINTENDED ACCELERATION. I WAS PRESSING SLIGHTLY ON THE ACCELERATOR PEDAL WHILE GOING UP A HILL WHEN THE ENGINE WENT INTO A WIDE OPEN THROTTLE CONDITION. I WAS ABLE TO MAINTAIN CONTROL OF THE VEHICLE AND TURNED-OFF THE IGNITION, ALLOWING THE VEHICLE TO COAST DOWN TO APPROXIMATELY 45 MPH. UPON TURNING THE IGNITION BACK TO "ON" THE VEHICLE AGAIN EXPERIENCED SUA AND ACCELERATED QUICKLY TO 60+ MPH. I AGAIN TURNED THE IGNITION SWITCH TO THE "OFF" POSITION AND ALLOWED THE VEHICLE TO COAST BACK DOWN. UPON TURNING THE IGNITION BACK TO "ON", THE ENGINE WENT BACK INTO A WIDE OPEN THROTTLE CONDITION AGAIN. AFTER FOUR TRIES (TURNING IGNITION "OFF", THEN "ON", THE ENGINE RPM RETURNED TO A NORMAL OPERATING CONDITION AND I WAS ABLE TO CONTINUE WITH MY TRIP. THERE WAS NO FLOOR MAT INTERFERENCE WITH THE ACCELERATOR PEDAL. THE SPEED CONTROL SYSTEM WAS NOT ACTIVATED. I AM A PILOT WITH 500 HOURS OF FLIGHT TIME AND RECENT ANNUAL CHECK RIDE QUALIFICATION/TRAINING TO HANDLE EMERGENCY SITUATIONS.
