MY 2008 JEEP GRAND CHEROKEE (5.8L) HAS A PERSISTENT PROBLEM WHERE THE ENGINE WILL SHUT OFF UNEXPECTEDLY. PROBLEM HAS BEEN ONGOING FOR 9 MOUNTS, AND 3 DIFFERENT DEALERS HAVE BEEN UNABLE TO DETERMINE THE CAUSE OF THE PROBLEM. PROBLEM OCCURS IN ALL DRIVING CONDITIONS, AND IS NOT REPEATABLE. SOMETIMES ENGINE SHUTS OFF VERY BRIEFLY (~.25 SECOND) AND PICKS UP WITH JUST A 'HICCOUGH' IN NORMAL OPERATION, SOMETIMES ENGINE SHUTS OFF FOR > 2 SECONDS, AND I NEED TO SHIFT TO NEUTRAL, AND RE-ENGAGE THE KEY TO START THE ENGINE. THE PROBLEM OCCURS AT RANDOM TIMES (ON CRUISE CONTROL ON STRAIGHT, FLAT HIGHWAY AT 65 MPH, IDLING AT STOP LIGHT, ACCELERATING INTO TRAFFIC, SLOWING FOR EXIT RAMP). SOMETIMES I WILL DRIVE FOR HUNDREDS OF MILES WITHOUT AN OCCURRENCE, SOMETIMES THE ENGINE CUTS OUT 5 TIMES IN A 5 MILE DRIVE. PROBLEM IS NOT REPEATABLE, AND NOT PREDICTABLE. *TR

2008 JEEP GRAND CHEROKEE LIMITED 5.7L HEMI 4X4. EXPERIENCING LOUD ENGINE NOISE WHEN FIRST STARTED. MOST NOTICEABLE WHEN ENGINE IS COLD. MORE PRONOUNCED ON COLDER DAYS THAN WARMER DAYS.

SINCE TURNING 38,000 MILES MY JEEP GRAND CHEROKEE 4X4 LIMITED HAS BEGUN TO STALL WITH REGULARITY. THE VEHICLE ALSO SHIFTS VERY HARD WHILE AT HIGHWAY SPEEDS. THE VEHICLE HAS STALLED WHILE STANDING AT A STOP, TRAVELING ON SECONDARY ROADS, AND HIGHWAY SPEEDS. THE DEALER HAS CHANGED SOME SENSORS ETC WITHOUT ANY SUCCESS. EVEN WORK DONE AT AN INDEPENDENT GARAGE HAS FAILED TO SOLVE ANYTHING. THIS VEHICLE HAS BECOME AN ABSOLUTE DEATH TRAP. I DEPEND ON THIS VEHICLE FOR WORK AND TO TRANSPORT MY 1 YEAR OLD. WHEN THE VEHICLE STALLS NO LIGHTS INDICATE AN ISSUE AND NO CODES ARE STORED. THE DEALER HAS SENT ME PACKING NUMEROUS TIMES. THEY ALWAYS SAY TO COME BACK WHEN A LIGHT COMES ON. I'VE TRIED TO EXPLAIN THAT THE NEXT TIME MAY BE THE LAST TIME. A SEARCH ONLINE SHOWED THAT MY SITUATION IS FAR FROM THE ONLY ONE. I'VE HAD NUMEROUS JEEPS OVER...

IT WOULD NOT ROLL DOWN. TL*THE CONTACT OWNS A 2008 JEEP GRAND CHEROKEE. WHILE DRIVING APPROXIMATELY 30 MPH ON NORMAL ROAD CONDITIONS, THE ENGINE UNEXPECTEDLY STALLED.

2008 JEEP GRAND CHEROKEE DIESEL 4X4. POWER LOSS, HESITATION, MOSTLY HAPPENS AT LOW SPEEDS AND GETS PROGRESSIVELY WORSE. THE VEHICLE IDLES FINE, THEN WHEN YOU STEP ON THE ACCELERATOR TO MOVE OUT INTO TRAFFIC IT SPUTTERS AND DOESN'T PROCEED AS EXPECTED. VERY SERIOUS SAFETY ISSUE ESPECIALLY SINCE THE COMPUTER SEES NO CODES SO THE DEALER DOESN'T KNOW WHERE TO START LOOKING. IT DOESN'T DO IT ALL THE TIME AND IT'S IMPOSSIBLE TO DETERMINE WHEN IT WILL DO IT. *TR
