2014 JEEP CHEROKEE Structurebody Problems

SHORTLY AFTER STARTING OUR 1500 MILE TRIP ON JULY 14 CROSSING A BRIDGE THE MONACO DIESEL PUSHER MOTORHOME TOWING A 2014 JEEP CHEROKEE 4X4 LATITUDE WITH ACTIVE DRIVE II SHOOK BADLY FRONT-TO-BACK AND SIDE-TO-SIDE AND WOULD NOT STOP UNTIL I PULLED OVER TO THE SIDE OF THE ROAD. NORMALLY A BUMP WILL CAUSE THE MH TO SHAKE FRONT-TO-BACK MOMENTARILY. I GOT OUT AND CHECKED AROUND AND UNDER BOTH VEHICLES AND FOUND NOTHING AMISS. GOT IN AND HEADED ON OUR TRIP. A COUPLE OF TIMES THAT DAY THE MH SHOOK WHEN HITTING A BUMP BUT NOT AS VIOLENTLY AS EARLIER. NO MORE SHAKING ON THE TRIP AND NO APPARENT DAMAGE. THE JEEP HAD BEEN DISENGAGED AND REENGAGED FROM THE MOTORHOME A COUPLE OF TIMES WITH NO SIGN OF DAMAGE. WE TRAVELED FROM BRYCE CANYON NATIONAL PARK TO CAPITAL REEF NP ON 20 JULY OVER A CURVY, HILLY HIGHWAY. AT CAPITOL REEF...

THE JEEP CHEROKEE HAS A PLASTIC SKID PLATE UNDERNEATH. THE FIRST INCIDENT HAPPENED WHEN I HIT A PUDDLE OF WATER, PULLING THE FRONT EDGE OF THE SKID PLATE LOOSE. AT THAT POINT, ANYTIME MY SPEED REACHED 45MPH IT WOULD VIBRATE, MAKING A VERY LOUD NOISE. I CALLED THE DEALERSHIP AND TOOK IT IN THE NEXT MORNING. THE TECH SAID HE SEES THIS ALL THE TIME, THE PLATE IS HELD ON WITH PLASTIC BOLTS. THEY REPAIRED IN 30 MIN, NO PAPERWORK. THE SAME THING HAPPENED AGAIN IN FEB2015. I TOOK THE VEHICLE IN TO THE DEALERSHIP FOR AN OIL CHANGE AND ASKED THAT THEY RE-SECURE THE SKID PLATE. I WAS ADVISE IT WAS DONE. IT HAPPENED AGAIN IN MAR2015, AND I RETURNED TO THE SAME DEALERSHIP FOR THIS PROBLEM, ALONG WITH SEVERAL RECALLS. I WAS TOLD THEY WOULD PUT METAL SCREWS IN TO REPAIR IT. THE 4TH TIME IT HAPPEND WAS...

NOTE: THIS ISSUE IS WITH THE 2014 JEEP GRAND CHEROKEE ECODIESEL ENGINE: ON THE 1ST OCCURRENCE, AFTER MERGING ON HIGHWAY WITH 4 PASSENGERS, AT APPROXIMATELY 55-60 MPG, VEHICLE BEGAN TO VIOLENTLY SHUDDER/VIBRATE, WITH SHUDDERING STEERING WHEEL DIFFICULT TO CONTROL. SHUDDERING STOPPED WHEN REMOVING FOOT FROM ACCELERATOR, AND STARTED SHUDDERING AGAIN WHEN I BEGAN ACCELERATING. IT HAPPENED SEVERAL MORE TIMES ON THE WAY HOME, AND HAS CONTINUED TO VIBRATE/SHUDDER INTERMITTENTLY EVERY DAY SINCE. IT SEEMS TO PRIMARILY HAPPEN AROUND 7TH/8TH GEAR AT 55-60MPH, BUT HAS ALSO HAPPENED GOING AROUND 40MPH. RESEARCH SHOWS THIS IS A COMMON PROBLEM WITH THE 2014 ECODIESEL ENGINE, AND COULD VERY EASILY CAUSE A FATAL ACCIDENT.

WHILE PULLING ONTO A STATE HIGHWAY, MY REAR LIFTGATE OPENED ON ITS OWN, EVEN THOUGH IT WAS SHUT AND LATCHED WHEN I INITIALLY TOOK OFF. THERE WERE NO WARNING BEEPS OR LIGHTS BEFORE OR DURING THIS EVENT. MY 35 POUND DOG WAS THROWN OUT ONTO THE HIGHWAY. *TR
