THE 2001 JEEP JUST CAME TO A STOP WHILE IT WAS BEING DRIVEN ON THE HIGHWAY. IT HAD ALWAYS HAD ENGINE ISSUES. THE FRONT WHEEL SUSPENSION ON THE PASSENGER SIDE OF THE 2001 JEEP CHEROKEE LAREDO IS BENT AND WHILE DRIVING IT ON THE STREET OR HIGHWAY IT CAUSES THE VEHICLE TO PULL TO THE LEFT AND IS UNSTABLE WHEN DRIVING IT ON A HIGHWAY OR STREET. THE ENGINE HAS A KNOCKING SOUND WHENEVER IT IS RUNNING. THE BRAKES TO THE VEHICLE HAS BEEN SLIPPING AND MAKING A GRINDING NOISE WHILE DRIVING IT. SOMETIMES THE JEEP DOESN'T WANT TO DRIVE OVER 70 MPH WHEN DRIVING IN THE HIGHWAY OR STREET. WE HAVE HAD TO REPLACE THE BRAKES BECAUSE THEY STARTED SMOKING WHILE DRIVING ON THE HIGHWAY. THERE IS ELECTRICAL ISSUES WITH THE CAR AS WELL WHERE THE RADIO DOESN'T PLAY AS WELL AS OTHER ELECTRICAL PARTS DON'T WORK. MY 2001 JEEP HAS STOPPED WHILE MY HUSBAND WAS DRIVING IT ON THE HIGHWAY AND IT IS NOT DRIVABLE. I HAVE HAD TO REPLACE THE IGNITION COIL AND SPARK PLUGS MANY TIMES FOR MANY YEARS. THERE HAS ALWAYS BEEN A WATER LEAK ON THE PASSENGER SIDE DRIPPING WHENEVER THE CAR IS IN MOTION, COMING FROM THE DASHBOARD ONTO THE CARPET SINCE THE CAR WAS PURCHASED. THERE MAY BE OTHER ISSUES WITH THE 2001 JEEP THAT I HAVE MISSED.

THIS JEEP WILL RUN FINE, BUT WHEN IT COMES TO RED LIGHTS AND IDLE, THE CAR WILL SHUT OFF AND NOT TURN ON AGAIN FOR ATLEAST 10 MINUTES. SPENT ABOUT 3,000 USD TO FIX AT MULTIPLE MECHANIC AND THE ISSUE REMAINS. WHY HAS JEEP NEVER TAKEN THE TIME TO RECALL THIS ISSUE AS IT CAN CAUSE THE LIVES OF MANY DRIVERS.

ON SEPT.2, 2014 I HAD MY 2011 JEEP GRAND CHEROKEE TOWED TO THE NEARSEST DEALER, MILFORD CHRYSLER, MILFORD, PA. I WAS DRIVING THE DAY BEFORE WITH FAMILY WHEN THE VEHICLE SUDDENLY STALLED IN AN ENTRANCE TO A PARKING LOT JUST AVOIDING AN ACCIDENT. MESSAGE CENTER SHOWED KEY NOT DETECTABLE. SEVERAL ATTEMPTS LATER IT TURNED OVER. TO PLAY IT SAFE I RETURNED HOME TO EXCHANGE VEHICLES. IT WAS MAKING HISSING SOUNDS SO I LEFT IT OUT OF THE GARAGE. THE NEXT DAY, IT WAS STILL MAKING NOISES. I CALLED FOR A TOW TO THE DEALER. I CALLED CHRYSLER AND THEY ADVISED ME OF A RECALL BUT THAT THE ENGINEERS WERE STILL TRYING TO DETERMINE WHY BUT THAT THE TIPM WAS MALFUNCTIONING. I WAS ALSO TOLD THAT A FINAL RECALL WOULD NOT COME OUT FOR ABOUT 3 MONTHS! I HAD NO CHOICE BUT TO GET MY VEHICLE REPAIRED. THEY HAD TO REPLACE THE BATTERY, FUEL PUMP, TIPM FOR A TOTAL OUT OF POCKET COST OF $2493.98. CHRYSLER EVENTUALLY REIMBURSED ME FOR THE TOTAL AMOUNT. ON NOVEMBER 20,2015 I WENT OUT AND FOUND THAT MY BLINKERS DID NOT WORK. IN FACT, WHEN ENGAGED, THE FOG LIGHTS BLINKED AND OR FLASHED. I TOOK IT TO MY ORIGINAL DEALER, R.I. SURESKY IN GOSHEN, NEW YORK. THEY RAN A SCAN AND FOUND THAT IT WAS CAUSED BY THE TIPM ! THIS MAKES TIPM #2!. I CALLED CHRYSLER, THE FINAL VERDICT, IT WAS NOT COVERED BY THE RECALL (FUEL PUMP RELATED ONLY). THE TECH REPLACED THE TIPM YET AGAIN AT AN OUT OF POCKET COST TO ME OF $1043.40. ON OCTOBER 21, 2016 THE ENGINE LIGHT CAME ON. I HAVE AN APPOINTMENT AT SURESKY'S ON MONDAY OCTOBER 24 TO RUN A DIAGNOSTIC ON IT. COULD IT BE TIPM RELATED? WE'LL SEE. I FEEL THAT CHRYSLER OWES ME $1043.40 FOR HAVING PARTS ( NEVER AVAILABLE IMMEDIATELY BY THE WAY) THAT ARE DEFECTIVE AND PLACE PEOPLE IN VERY DANGEROUS SITUATIONS ON THE ROAD.

I TOOK MY VEHICLE INTO LARSON JEEP DODGE IN PUYALLUP, WA TO HAVE TWO RECALLS PREFORMED. ONE OF THE OPEN RECALL CAMPAIGNS ARE RECALL F25. THIS RECALL INVOLVES REPLACING THE ELECTRIC COOLING FAN. IF NOT REPLACED IT COULD SEPARATE CAUSING DAMAGE TO THE RADIATOR, ENGINE, OR BODILY INJURY. I PICKED UP MY VEHICLE ON THE DAY THAT IT WAS IN THE SERVICE DEPARTMENT. I SIGNED AND WAS GIVING A REPAIR ORDER NUMBER JECS380694 DATED 2/25/2016. THE INVOICE STATES THE RECALL WAS PREFORMED AND THE COOLING FANS WERE REPLACED AS DIRECTED BY THE RECALL CAMPAIGN. ON THE DRIVE BACK TO MY RESIDENCE I NOTED A RATTLE COMING FROM THE FRONT OF MY VEHICLE WITH INCREASED SPEED OR WHEN DRIVING OVER BUMPS. WHEN I RETURNED TO MY RESIDENCE I OPENED THE HOOD TO FIND OUT WHAT WAS CAUSING THE RATTLE. I NOTICED NONE OF THE UPPER GRILL BOLTS WERE INSTALLED AND THE GRILL WAS LOOSE. I THEN INSPECTED THE LOWER SKID PLATE OF THE VEHICLE AND NOTICED IT WAS LOOSE AND UNFASTENED AS WELL. I THEN INSPECTED THE COOLING FAN BLADES AND FOUND THEY HAD NOT BEEN REPLACED AS DIRECTED BY THE RECALL OR AS STATED ON THE REPAIR ORDER. I HAVE ATTACHED A COPY OF THE REPAIR ORDER AND PICTURES OF THE UNREPAIRED VEHICLE. I HAVE OPENED A CASE WITH DAIMLER CHRYSLER, CASE #28814838. I DID RETURN BACK TO LARSON DODGE 2/26/2016 AND REQUESTED THE HARDWARE BACK TO FASTEN MY GRILL AND SKID PLATE. THE SERVICE MANAGER AND SHOP FOREMAN INSPECTED MY VEHICLE AT THAT TIME. THEY INSPECTED, DETERMINED, AND ADMITTED THE RECALL WAS NOT PREFORMED. I INFORMED THEM I WOULD BE RETURNING HOME AND CONTACTING THE VEHICLES MANUFACTURER.

MY JEEP GRAND CHEROKEE LOST POWER WHILE DRIVING. I WAS ABLE TO PULL OVER WITH DIFFICULTY. I THEN PUT IN PARK AND WAS ABLE TO GET ENGINE STARTED AND DROVE BACK HOME. MY HUSBAND CHECKED OUT AND THOUGHT I MIGHT HAVE BUMPED THE KEY SINCE I NEED THE SEAT SO CLOSE IN ORDER TO TOUCH THE PEDALS. I HEARD ON THE TV THERE WAS A RECALL ON MODELS 2005-2007. WHY NOT ON OLDER? IF I HAD BEEN GOING ANY FASTER I MIGHT NOT HAVE BEEN ABLE TO STEER TO THE SIDE.

ENGINE

COMPLETE ENGINE FAILURE CAUSED THE VEHICLE TO SUDDENLY LOOSE ALL POWER. UPON FURTHER INVESTIGATION, THE PISTON SKIRT HAD CRACKED AND EVENTUALLY BROKE AWAY CAUSING A COMPLETE FAILURE OF THE ENGINE. RESOLUTION WAS TO REPLACE THE ENGINE. THIS IS A FAIRLY COMMON PROBLEM WITH THE JEEP 4.0 ENGINE AFTER THE PISTON WAS REDESIGNED AROUND 2000-2001. JEEP SHOULD HAVE RECALLED THE VEHICLES AND REPLACED THE PISTONS BEFORE THEY STARTED CRACKING AND CAUSING ENGINE FAILURES. *TR UPDATED 05/29/13

ENGINE AND ENGINE COOLING

THE HEAD CRACKING ISSUE SEEMS TO BE THE RESULT OF SEVERAL BAD CASTINGS AND I CAN ONLY SPECULATE THAT THE CAST IRON USED IN ONE LARGE BATCH MADE AROUND THE YEAR 2000 MUST HAVE BEEN OF POOR QUALITY. THE AREA BETWEEN THE NO.3 AND 4 EXHAUST PORTS IS THE HOTTEST PART OF THE HEAD AND IS SUBJECTED TO THE LARGEST TEMPERATURE FLUCTUATIONS, MAKING THAT THE AREA MOST PRONE TO CRACK. THE FIRST SIGN OF A PROBLEM IS UNEXPLAINED LOSS OF COOLANT. IF THERE ARE NO EXTERNAL COOLANT LEAKS, REMOVE THE OIL FILLER CAP AND LOOK BETWEEN THE VALVE SPRINGS OF THE NO.3 AND 4 CYLINDERS.

APPROXIMATELY 5 YEARS AGO, THE HEAT STOPPED WORKING ON THE PASSENGER SIDE OF MY 2001 JEEP GRAND CHEROKEE. THEN LAST YEAR, THE HEAT AND A/C STOPPED WORKING COMPLETELY. THIS MAKES FOR VERY DANGEROUS DRIVING CONDITIONS AS VISIBILITY IS GREATLY REDUCED AT TIMES. ITS TOO COSTLY FOR ME TO REPAIR MYSELF. IT APPEARS THAT THIS IS A PROBLEM FOR MOST OF THESE VEHICLES AND I CAN'T UNDERSTAND WHY SOMETHING HASN'T BEEN DONE ABOUT IT. ALSO, THE PASSENGER SIDE SEAT HEATING ELEMENT STOPPED WORKING AFTER IT APPARENTLY SHORTED OUT, LUCKILY, NO FIRE OCCURRED. AND THE HYDRAULICS THROUGH OUT THE VEHICLE HAVE STOPPED WORKING AND I NOTICED THIS WHEN FIRST THE HOOD CAME DOWN ON MY HEAD AND THEN THE REAR WINDOW! I'VE ALSO HAD TO REPLACE THE ENGINE AND IT WAS DUE TO PROBLEMS WITH THE COOLANT/HYDRAULIC FAN...AT A PRICE TAG OF $4000.00...

ENGINE AND ENGINE COOLING

REPEATED FAILURE OF BLOWER FAN FOR WHICH THERE IS APPARENTLY NOT A SUITABLE FIX FROM JEEP. CURRENT FIX IS EITHER (A) PART FROM SUPPLIER OTHER THAN JEEP WHICH FAILS EVERY 6-9 MONTHS OR (B) JEEP RECOMMENDED PART WHICH REDUCED AIR VOLUME SO DRAMATICALLY THAT DEFROSTING WINDOWS IS UNSAFE. FAILURE OF THE BLOWER MOTOR IS ALSO UNSAFE DUE TO THE INABILITY TO DEFROST THE WINDOWS.

ENGINE AND ENGINE COOLING

THE CAR OVERHEATED AND YOU CAN HEAR THE BOILED COOLANT FLUSHING BACK INTO THE RESERVOIR AND POURING OUT THROUGH THE DRAIN. THIS I FOUND OUT WAS CAUSED DUE TO THE MALFUNCTIONING OR RATHER ELECTRICAL SHORTING OF THE ECM (ENGINE CONTROL MODULE) LOCATED IN THE HOOD NEAR THE FIREWALL BEHIND THE COOLANT RESERVOIR. THIS CAUSES A FAILURE IN THE ELECTRICAL SYSTEM SO THE FAN THAT IS SUPPOSED TO KICK ON WHEN YOU TURN ON THE AIR FAILS TO START. I ALSO RECENTLY REPLACED MY INLINE-6 DUE TO A CRACK IN THE ENGINE BLOCK CAUSING THE COOLANT TO FLOW AND MIX WITH THE OIL THEREFORE, RESULTING IN LOW LEVELS OR COOLANT IN THE RESERVE AND THE RADIATOR. IT ALSO CAUSES THE OIL LEVEL TO INCREASE DRASTICALLY.
