2010 Jeep Grand Cherokee

VEHICLE CONTINUES TO HESITATE AND MISFIRE UPON STARTUP. OBD CODE P303 FOR CYLINDER #3 MISFIRE. AFTER A FEW MINUTES, THE PROBLEM GOES AWAY. DOESN'T HAPPEN EVERY TIME, AND IN NO PARTICULAR WEATHER CONDITIONS OR TEMPERATURES. MAY BE DANGEROUS IF PULLING OUT OF A PARKING AREA OR SOME OTHER LOCATION ONTO A STREET, AS VEHICLE WILL BUCK AND REFUSE TO ACCELERATE FOR A FEW MOMENTS. MY RESEARCH HAS FOUND THAT THIS APPEARS TO BE A COMMON PROBLEM, AND RECALLS WERE ISSUED IN OLDER MODELS BUT NOT THIS PARTICULAR YEAR SO FAR.

OUR 2010 JEEP GRAND CHEROKEE HAS BEEN SHUTTING OFF IN MANY DIFFERENT OCCASIONS SINCE MAY 2017. WE'VE TAKEN IT TO OUR LOCAL MECHANIC AND HE SUGGESTED WE GO DIRECTLY TO THE DODGE/JEEP DEALERSHIP. NOBODY CAN FIND WHAT IS CAUSING THIS BUT SAY THIS IS A KNOWN ISSUE. WHILE DRIVING THE VEHICLE AT VARYING SPEEDS, INCLUDING SITTING STILL IDLING, TRAVELING 25 MPH ON MUNICIPAL ROAD, 60+MPH ON HWY. WHEN THIS HAPPENS THE WHOLE CAR SHUTS OFF LEAVING US UNABLE TO STEER, LOSS OF BREAKS, LOSS OF POWER STEERING, LOSS OF POWER TO THE WHOLE JEEP, ENGINE SHUTS OFF AND LOSS OF ABILITY TO CONTROL THE VEHICLE TO SAFETY. STALLING IN MOVING TRAFFIC WHEN YOU DON'T EXPECT IT HAS INHERENT RISK AND THE LOSS OF POWER SYSTEMS LIKE BRAKES AND STEERING THAT ACCOMPANIES A VEHICLE STALL MAKES GETTING OUT OF THE WAY DIFFICULT. LOSING ALL ABILITY TO ACCELERATE OR USE POWER STEERING. WE'VE HAD TO RUN THE VEHICLE OFF THE ROAD IN THE MIDDLE OF TRAFFIC INTO A FARM PASTURE IN ORDER TO GET TO SAFETY. THE JEEP HAS LOST POWER ON THE HWY TRAVELING 60+MPH AND HAD TO VEER OFF IN ORDER TO CONTROL THE JEEP AND GET TO SAFETY. THIS IS OUR MAIN CAR TO TAKE MY WIFE TO WORK AND OUR DAUGHTER TO AND FROM SCHOOL. WE'VE HAD TO LEAVE THE CAR IN THE DRIVEWAY DUE TO LIFE SAFETY CONCERNS. MY LOCAL DODGE/JEEP DEALERSHIP SAYS THIS IS A KNOWN ISSUE BUT DON'T KNOW HOW TO RESOLVE THIS POTENTIAL LIFE THREATENING ISSUE IS VERY CONCERNING AND WE WOULD APPRECIATE YOUR HELP IN RESOLVING THIS MATTER.

WHEN I TRY TO START MY CAR I TURN THE KEY AND ALL THE LIGHTS COME ON BUT THE CAR WILL NOT START. THE BATTERY IS NEW. THE STARTER DOESN'T ENGAGE AT ALL. ALSO WHEN I TRY TO LOCK OR UNLOCK THE CAR WITH THE KEY FOB I HAVE TO PRESS THE KEY FOB 10-15 TIMES TO GET IT TO WORK. I BROUGHT IT TO MY LOCAL DEALER MULTIPLE TIMES FOR THE SAME ISSUE AND THEY SAID THERE WASN'T ANYTHING WRONG WITH IT.

I WAS DRIVING APPROXIMATELY 70MPH ON INTERSTATE 75 SOUTHBOUND WEDNESDAY MAY 17, 2017. ALL OF SUDDEN MY SEVERAL LIGHTS ON DASHBOARD CAME ON - ENGINE LIGHT, ABS, ELECTRIC THROTTLE WARNING LIGHT. MY JEEP STARTED DECELERATING VERY QUICKLY. I PUT ON MY HAZARDS AS I TRIED TO PULL OVER TO SIDE OF ROAD. ONCE I WAS ON SIDE OF INTERSTATE, I PUSHED ON GAS PEDAL AND ENGINE REVVED BUT THE CAR DIDN'T ACCELERATE AND SPEEDOMETER STAYED AT 0. I IMMEDIATELY CALLED TOW SERVICE AND BROUGHT CAR TO FERMAN JEEP IN LUTZ, FLORIDA. AT COST OF 400.00 FOR INSPECTION, I WAS TOLD ENGINE CHAIN GUIDE FAILED CAUSING MY TIMECHAIN TO SNAP AND SHREDDED MY OIL PUMP AND BENT CRANK SHAFT. THAT WAS JUST THE INITIAL ANALYSIS. AND FERMAN WANTED TO AUTHORIZE AN ADDITIONAL 400.00 TO LOOK FURTHER INTO ENGINE. AT THAT POINT, WE DISCUSSED HOW MUCH REPAIRS WERE GOING TO BE AND OUR SERVICE ADVISOR SAID AT THAT POINT A NEW ENGINE WOULD BE BEST. I AM VERY CONCERNED BECAUSE A QUICK INTERNET SEARCH REVEALS 5.7LITER HEMI ENGINE RECALL FOR DODGE AND CHYRSLER CARS FROM 2009-2012 FOR THIS EXACT REASON. MY SERVICE ADVISOR SAID THE JEEP HEMI ENGINE WAS SAME ENGINE AS DODGE AND CHRYSLER ENGINE INVOLVED IN RECALL. I WAS AT SAME MILEAGE RANGE THAT PEOPLE DISCUSSED ON INTERNET WITHIN THAT RECALL AND DRIVING AT SAME SPEED AND DRIVING AUTOMATIC TRANSMISSION. I CONTACTED JEEP CUSTOMER SERVICE AND WAS TOLD THEY COULDN'T HELP ME BUT WOULD MAKE A NOTE FOR SAFETY REASONS. I REALLY FEEL NHTSA NEEDS TO EXPLORE THAT JEEP SHOULD EXTEND RECALL TO GRAND CHEROKEE ENGINES AT 5.7 HEMI.

TL* THE CONTACT OWNS A 2010 JEEP GRAND CHEROKEE. THE CONTACT STATED THAT THE VEHICLE FAILED TO START WHEN THE ENGINE GOT COLD. IN ADDITION, THE CONTACT STATED THAT THE IGNITION MADE A CLICKING NOISE WHILE ATTEMPTING TO START THE VEHICLE. THE VEHICLE WAS TAKEN TO THE DEALER WHERE IT WAS DIAGNOSED THAT THE IGNITION SENSOR FAILED AND NEEDED TO BE REPLACED. THE VEHICLE WAS REPAIRED; HOWEVER, THE FAILURE RECURRED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 102,000.

WHILE DRIVING THE CAR AND BRAKING THE PEDAL WILL DROP ABOUT HALF WAY AND THEN RECOVER TO NORMAL USE. I HAVE OWNED THE CAR FOR ABOUT 4 YEARS AND IT HAS HAPPENED AT LEAST FIVE TIMES STARTLING THE DRIVER. THE CAR HAS BEEN TO A FEW MECHANICS AND THEY HAVE FOUND NOTHING WRONG. I BELEIVE IT COULD BE RELATED TO THE 2011 RECALL FOR BOOSTERS IN JEEPS.

TL* THE CONTACT OWNS A 2010 JEEP GRAND CHEROKEE. WHILE ATTEMPTING TO PARK THE VEHICLE, THERE WAS AN ABNORMAL CLICKING SOUND COMING FROM THE ENGINE COMPARTMENT. THE VEHICLE ACCELERATED INDEPENDENTLY AND CRASHED INTO SEVERAL OUTDOOR LIGHTING STRUCTURES AT A NEIGHBORING RESIDENCE. A POLICE REPORT WAS FILED. THE CONTACT WAS NOT INJURED. THE VEHICLE WAS TOWED TO THE DEALER TO BE DIAGNOSED. THE CONTACT WAS INFORMED THAT THE MECHANIC WAS UNABLE TO DUPLICATE THE FAILURE OR RETRIEVE A FAULT CODE. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS 109,000.
