Open the full vehicle complaint log (all categories)WHILE DRIVING THROUGH A GROCERY STORE PARKING LOT, THE VEHICLE SUDDENLY ACCELERATED TO 4000RPM. THANKFULLY, DUE TO QUICK THINKING, I GOT ON THE BRAKES, PUT THE CAR IN NEUTRAL AND TURNED THE IGNITION OFF. SOMETHING IS SERIOUSLY WRONG. THANK GOD I DIDN'T MOW DOWN THE 4 PEOPLE WALKING IN FRONT OF ME. A QUICK SEARCH OF THE INTERNET REVEALS THIS TO BE A COMMON PROBLEM WITH JEEPS. HOW IN THE WORLD HAS THIS ISSUE NOT BEEN A RECALL??!!
I OWN A 2009 JEEP LIBERTY WITH 2000 MILES ON IT. TWICE IT HAS SUDDENLY ACCELERATED ON IT'S OWN WHEN I WAS STARTING FROM A STOPPED POSITION TO PULL INTO A PARKING SPACE. THE FIRST TIME I WAS ABLE TO STOP IT USING THE BRAKES BEFORE IT JUMPED OVER THE CURB. THE SECOND TIME IT HAPPENED SO FAST I COULDN'T STOP IT IN TIME AND IT HIT A LARGE CONCRETE COLUMN IN FRONT OF THE PARKING SPACE. THE CAR SUFFERED QUITE A LOT OF BODY DAMAGE AND WILL BE IN A BODY SHOP FOR 3 OR MORE WEEKS. I SUFFERED SEVERAL SKIN WOUNDS ON MY HAND AND ARM AND A SPRAINED THUMB. AFTER TALKING WITH SEVERAL MECHANIC FRIENDS, HERE IS WHAT I THINK MIGHT HAVE HAPPENED. IN BOTH CASES I WAS MAKING AN EXTREME LEFT TURN INTO A RIGHT-SLANTED PARKING SPACE FROM A TWO-LANE AISLE. IN BOTH CASES I HAD JUST CROSSED OVER A SAFETY BUMP AND STOPPED TO LET ONCOMING TRAFFIC GO BY BEFORE I TURNED. IN BOTH CASES, IT WAS HOT AND MY AIR CONDITIONER WAS TURNED TO HIGH. THE COMBINATION OF THE LOAD OF THE AIR AND THE POWER STEERING COULD HAVE BEEN ENOUGH TO SHOW UP A DEFECT IN THE ELECTRONIC CONTROL THROTTLE SENSOR SOFTWARE AND CAUSE THE SUDDEN ACCELERATION. THIS IS THE ONLY EXPLANATION THAT I HAVE BEEN ABLE TO FIND. I'M SURE IT WAS NOT DRIVER ERROR. I HAVE DRIVEN JEEPS FOR MANY YEARS AND NEVER HAVE HAD AN ACCIDENT IN ALL MY YEARS OF DRIVING. I WOULD APPRECIATE YOUR ANALYSIS OF THIS PROBLEM BEFORE IT RESULTS IN MORE SERIOUS ACCIDENTS FOR JEEP LIBERTY OWNERS. *TR THANK YOU
