My 2007 Crown Victoria has had a worsening unintended acceleration issue over the past year. When hitting hard bumps the car will suddenly begin revving my itself (normal RPM is 600 idling in drive and 800 idling in neutral) when this issue occurs it will sit around 1k rpm in drive (pushing against the brakes so I must hold them down very hard) and will shoot up to 2k rpm in neutral. when the issue is occurring it drives the car forward with no user input. this issue has been becoming more and more frequent with it happening up to 5 times in a 15 minute drive. It is very unsafe and has caused me to hit a parking pole before as I could not slow the car down fully.

I CAME TO NORMAL STOP AT 4 WAY STOP SIGN. STARTED ACROSS ROAD AND VEHICLE TO MY LEFT FAILED TO YIELD RIGHT OF WAY AND I HAD TO PANIC STOP. AS I HIT BRAKES FOR PANIC STOP, ENGINE RPM WENT TO MAX, PULLING CAR FORWARD WHILE I WAS HARD ON BRAKES. I MISSED VIOLATOR BY ONLY INCHES. AS SOON AS I LET OFF BRAKES, ENGINE RPM RETURNED TO NORMAL. FORD DEALER HAS PREVIOUSLY CONCLUDED I HIT GAS INSTEAD OF BRAKES. THIS IS TOTALLY ABSURD IN EVERY INSTANCE OF THIS EVENT. HAD I HIT THE BRAKES IN THIS LATEST INCIDENT, I WOULD HAVE TOTALED THE CAR I WAS TRYING TO AVOID. I AM REPORTING THIS INCIDENT (ONE OF AT LEAST A HALF DOZEN PREVIOUS INCIDENTS) BECAUSE THIS WAS SO CLOSE TO AN ACCIDENT. IN PAST INCIDENTS I HAVE STOPPED "BRAKE/INCREASE RPM" BY SIMPLY CUTTING OFF IGNITION. THIS REPORTED INCIDENT HAPPENED SO FAST, I HAD NO TIME TO CUT IGNITION, NOR WOULD THIS HAVE BEEN A GOOD TIME TO CUT IGNITION. *TR

I DRIVE A FORD "PROGRAM CAR" - A USED 2007 CROWN VICTORIA (A FORMER RENTAL VEHICLE). ON THE DAY OF MY ACCIDENT - AFTER PULLING ONTO A BUSY STREET FROM A PARKING LOT - I ALMOST IMMEDIATELY APPLIED MY BRAKES BECAUSE I WAS COMING UP TO A RED LIGHT WHERE SEVERAL CARS HAD ALREADY COME TO A STOP AHEAD OF ME. AT FIRST MY CAR SLOWED NORMALLY BUT, AS I APPLIED THE BRAKES TO COME TO A COMPLETE STOP, THE ENGINE BEGAN TO REV' UP. I TRIED TAPPING THE BRAKE TO SEE IF THIS WOULD HELP TO DISENGAGE THE THROTTLE'S REVVING. IT DIDN'T HELP. I KEPT TRYING THIS. I HAD LITTLE TIME TO COME TO A STOP BEFORE HITTING THE CAR IN FRONT OF ME SO I REALLY "STOOD" ON THE BRAKES. UNFORTUNATELY, I HIT THE BACK BUMPER OF THE CAR IN FRONT OF ME. LUCKILY, THERE WAS NO VISIBLE DAMAGE TO EITHER CAR AND NO ONE WAS HURT. THIS SAME SITUATION HAPPENED TO ME ABOUT 2-3 WEEKS BEFORE THIS ACCIDENT OCCURRED BUT THAT OCCURRENCE DIDN'T RESULT IN AN ACCIDENT. I WAS ABLE TO TAP THE BRAKE PEDAL AND THE REVVING SEEMED TO INSTANTLY GO AWAY. I HAD A PASSENGER WITH ME AT THE TIME. I HAD THE SAME THING HAPPEN WITH ANOTHER SIMILAR CAR IN THE PAST - A MERCURY GRAND MARQUIS. IT HAPPENED MORE THAN ONCE AND NO MATTER HOW OFTEN I WENT TO THE DEALERSHIP TO GET HELP THEY KEPT TELLING ME THEY COULD NOT "REPLICATE" THE COMPLAINT. I TOOK MY CURRENT CROWN VICTORIA TO THE DEALERSHIP ONE DAY AFTER HAVING THIS MINOR ACCIDENT. THE CAR WAS DUE FOR A SERVICE VISIT AND I TOLD THEM ABOUT THE MINOR ACCIDENT AND ASKED THEM TO SEE WHAT THEY COULD FIND OUT. AGAIN, I WAS TOLD THEY COULD NOT REPLICATE THE COMPLAINT. I KNOW I'M NOT THE ONLY PERSON WHO HAS HAD THIS HAPPEN AS A CLASS ACTION SUIT HAS BEEN FILED AGAINST FORD IN MARCH IN WEST VIRGINIA ON BEHALF OF OWNERS IN 14 STATES! APPARENTLY, THIS IS NOT A ONE TIME THING WITH THESE VEHICLES. *TR

THIS IS ANOTHER OF AN ON GOING ACCELERATION ISSUE WHEN DEPRESSING THE FOOT BRAKE. IN THIS INSTANCE I HAD JUST BACKED OUT OF A PARKING SPACE IN A SHOPPING CENTER AND DROVE MAYBE 200' AND HAD JUST ABOUT ROLLED TO A STOP SIGN FOR GA HIGHWAY 212 AND VERY SLIGHTLY DEPRESSED THE BRAKE PEDAL TO COME TO A COMPLETE STOP. AS SOON AS I STARTED PRESSING THE BRAKE PEDAL, THE ENGINE PICKED UP RPM AND I IMMEDIATELY MOVED FOOT FROM BRAKE PEDAL. END OF ACCELERATION. BY THIS TIME VEHICLE HAD ALREADY ROLLED TO A COMPLETE STOP. I DID NOT, AS FORD SEEMS TO THINK, HAVE MY FOOT ON BOTH THE GAS AND BRAKE. THE VERY LIGHT PRESSURE I HAD APPLIED WOULD HAVE MY FOOT THREE TO FOUR INCHES AWAY FROM THE TOP OF THE GAS PEDAL. YES, I HAD MY FOOT ON THE BRAKE. I HAD TO REMOVE MY FOOT FROM THE GAS TO GET TO THE BRAKE. THIS IS A VEHICLE MALFUNCTION. NOT OPERATOR ERROR. I AM UNABLE TO DETERMINE A FAILED COMPONENT.....FUEL? BRAKE? ELECTRICAL? I DON'T HAVE A CLUE.

FORD CROWN VIC POLICE INTERCEPTOR,2007: ON TWO PREVIOUS OCCASIONS, UPON DEPRESSING BRAKE PEDAL AT STOP SIGN, ENGINE WOULD SEEM TO BEGIN TO RACE; HOWEVER, AFTER STOP I WOULD IMMEDIATELY LET OFF BRAKE TO GO ON THROUGH STOP SIGN AND ENGINE WAS NORMAL ON ACCELERATION. TO-DAY AS I LEFT MY PARKING SPACE I APPROACHED AN AUTOMATIC GATE TO PASS THROUGH AND DEPRESSED BRAKE PEDAL TO WAIT FOR GATE TO OPEN AND ENGINE BEGAN TO RACE TO THE POINT THAT I WAS UNABLE TO HOLD VEHICLE BACK AND TURNED OFF IGNITION TO AVOID HITTING GATE. A LARGE AMOUNT OF BLACK SMOKE RESULTED FROM RACING ENGINE. AFTER ENGINE SHUT-DOWN, I SHIFTED TO PARK, STARTED ENGINE AND HAD NORMAL IDLE. I DEPRESSED BRAKE TO SHIFT INTO DRIVE AND PROCEEDED THROUGH GATE IN NORMAL MANNER. THE ONLY COMMON SYSTEM THAT I AM AWARE OF (OTHER THAN POSSIBLE ELECTRICAL/COMPUTER) TO THE FUEL CONTROL IS THE VACUUM SYSTEM ASSOCIATED WITH THE BRAKE VACUUM BOOSTER AND WHATEVER VACUUM MAY AFFECT THE FUEL FEED. THE FOOT PEDAL WAS DEFINITELY IN AN IDLE POSITION. I AM CERTAIN THAT THIS ENGINE RACING PROBLEM IS INITIATED BY MY APPLYING BRAKES. *TR

Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
