WHILE PARKING IN A PARKING LOT WITH MY FOOT ON THE BRAKE PEDAL, THE ENGINE RPM'S SURGED AND I HAD TO APPLY EXTREMELY HARD FORCE ON THE BRAKE PEDAL AND SHIFT INTO NEUTRAL TO STOP AFTER TRAVELING 10 TO 15 FEET. THIS HAPPENED AGAIN AND I TOOK THE JEEP TO YARK SERVICE IN TOLEDO OH. THEY RAN A DIAGNOSIS AND COULD NOT FIND ANY CODES. MY WIFE TOOK THE JEEP AND WHILE PARKING HAD THE SAME PROBLEM. BEFORE SHE COULD STOP THE VEHICLE RAN INTO A POST AND SUSTAINED DAMAGE. I CALLED JEEP CUSTOMER SERVICE AND REPORTED IT AS A SAFETY PROBLEM ON AUG 31. I WAS TOLD TO TAKE IT BACK TO THE SERVICE DEPT. THEY SAID NOTHING COULD BE DONE AT THAT TIME. I TOOK IT BACK THE NEXT WEEK AND THE SERVICE MANAGER WAS NOT AVAILABLE. *TR
