2003 Jeep Grand Cherokee vehicle speed control problems

“JUST RECENTLY IN THE LAST THREE MONTHS FRONT PASSENGER WINDOW FELL WHILE DRIVING AND BACK DRIVER WINDOW FELL WHILE DRIVING WHILE IT WHAT SNOWING WHILE MY SON WAS IN THE CAR. HAVE A POPPING NOISE IN STEERING OR SOMEWHERE IN FRONT END. I CAN'T USE MY ACCELERATE BUTTON ON STEERING WHEEL WHILE IT'S IN CRUISE BECAUSE IT WON'T STOP ACCELERATION ONCE YOU PRESS IT. I WAS GOING ABOUT 55 AND WAS TRYING TO ACCELERATE TO 60.”

“I STARTED MY JEEP, NOTICED MY HATCH WAS NOT CLOSED, GOT OUT WHILE IT WAS RUNNING, THE SECOND I CLOSED MY DRIVER DOOR, MY JEEP WENT INTO REVERSE ON ITS OWN, AND KEPT ACCELERATING HIGHER, THIS VEHICLE TOOK OFF VERY AGGRESSIVELY, LUCKILY MY WIFE WAS IN THE PASSENGER SEAT, SHE PUT IT IN NATURAL, AND SHUT THE CAR OFF BEFORE ANYTHING WAS STRUCK, NOW DUE TO I BELIEVE THE RAPID ACCELERATION IT RUNS HORRIBLY WHEN I PUT IT IN DRIVE. THIS JEEP IS AN 2003 , WELL BROKE IN AND MAINTAINED, THERE'S NO OTHER REASON AS TO WHY IT "BECAME SELF AWARE" I HAVE A LOT OF VEHICLE KNOWLEDGE AND THIS IS VIRTUALLY AND UNFATHOMABLY IMPOSSIBLE , PLEASE REVIEW EVERY ASPECT OF THIS VEHICLES COMPLAINTS AS THIS IS VERY UNSAFE”

“WHILE THE CAR WAS STOPPED IN A PARKING LOT, THE IDLE SUDDENLY STARTED RACING AT WELL OVER 1000 RPM. EVEN MAX PRESSURE ON THE BRAKE PEDAL WAS NOT ENOUGH TO PREVENT THE CAR FROM MOVING. I SHIFTED INTO NEUTRAL FROM DRIVE TO PREVENT RUNNING OVER A PEDESTRIAN. THE IDLE RETURNED TO NORMAL SEVERAL SECONDS LATER. THE ACCELERATOR PEDDLE WAS NOT IN ANY WAY INVOLVED. A MORE LIMITED RACING OCCURRED WHEN I FIRST BEGAN THE TRIP WHILE I WAS MAKING A SLOW LEFT TURN FROM A STOPPED POSITION AT A TRAFFIC LIGHT. I HAVE BEEN DRIVING SAFELY FOR OVER 54 YEARS AND HAVE NEVER HAD AN EXPERIENCE TO COMPARE WITH THIS ONE. IT WAS TRULY A WHILE KNUCKLE RIDE!”
