MY 2004 JEEP LIBERTY WAS PARKED UNDER MY CARPORT. I HAD STARTED THE ENGINE TO WARM THE CAR, WITH THE EMERGENCY BRAKE ON. THERE WAS NO ONE AROUND THE CAR BUT MY DOGS, BUT SOMEHOW IT MANAGED TO ROLL DOWN THE DRIVEWAY INTO THE CORNER OF A BARN. THE DISTANCE WAS ABOUT 10 YARDS WITH AN INCLINE OF ABOUT 2 FEET, YET THER WAS OVER $3000.00 IN DAMAGE TO THE CAR. IT HIT RIGHT IN THE CENTER OF THE GRILL/HOOD. I WAS VERY SURPRISED AS THE EMERGENCY BRAKE WAS ON, HOWEVER ON INSPECTION, THERE WAS STILL ONE CLICK LEFT ON THE EMERGENCY BRAKE. I HAVE TESTED THIS THEORY BY GETTING ON A HILL IN THE VEHICLE AND PULLING THE EMERGENCY BRAKE. INDEED, IT DOES NOT HOLD THE VEHICLE UNTIL YOU REACH THE VERY LAST CLICK ON THE EMERGENCY BRAKE. JEEP DENIES ANY PRODUCT FLAW WHEN CONTACTED. I DISAGREE. I HATE TO THINK WHAT WILL HAPPEN TO ME IF I AM EVER IN A WRECK IF A ROLL WITH NO ACCELERATION CAN DAMAGE THE VEHICLE AT 25% OF ITS VALUE!
