On [XXX] I was driving this recently purchased Grand marquis . On [XXX] here in San Antonio around ten at night I hit the brakes and something under the hood compartment blew up and it cocked the car . I was trapped inside and when I finally was able to get my seatbelt released I had to break the window with my head . The previous week I reached out to ford and they told me they would address the issue and that they would call me back and that was to no avail. i reached out to ford and at first I was told I would be helped and then a man came on the phone yelling that my vehicle . I need help with resol this issue . My car is totaled and I’m hurting and it’s because of a car with recalls that are a fire haz and dangerous to be put on the road Thank you and God Bless . was not under any recalls The car had been parked for over ten years beca when the orig owner bought it it had issues with the cruise control and the brakes and the engine and the lights . I investigated about and hazards the car was demonstrating and upon further consideration my instinct told me this car was defected and was a big problem waiting to happen INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

THIS CAR HAS A DANGEROUS DEFECT. RANDOMLY WHEN IN A STATIONARY POSITION, BY HOLDING THE BRAKES, THE ENGINE AND TRANSMISSION SOMETIMES SUDDENLY ACCELERATES POWERFULLY, MAKING IT DIFFICULT TO HOLD THE CAR. I NOTIFIED THE DEALER ABOUT THIS DEFECT, SEVERAL TIMES IN WRITING AND BY PHONE. DEC, 29, 2005 THEY TOOK IT ON A DRIVE, AND CLAIMED TO HAVE FOUND NO DEFECT. SUBSEQUENTLY, JAN, 15, 2006 AT APPROXIMATELY 1:00 PM, I WAS STOPPED AT A RED LIGHT ON GRAND ST. NYC BEHIND AN SUV, BY HOLDING THE BRAKES, ALL OF A SUDDEN IT ACCELERATED, AND IT WAS IMPOSSIBLE TO HOLD THE CAR. IT SLAMMED INTO THE SUV IN FRONT OF ME, SMASHING MY FRONT. LUCKILY, THE SUV WAS NOT DAMAGED. BUT EVEN MORE LUCKILY, WE DID NOT GET HURT, (I HAD IN THE CAR MY WIFE, AN ADULT DAUGHTER, AND 2 GRAND CHILDREN). IN ADDITION, I GUESS WE WERE EXTRA LUCKY THAT WE HAD THE SUV IN FRONT OF ME, WHICH AVERTED A CATASTROPHIC MOWING DOWN OF PEDESTRIANS CROSSING. THE DEALERS TOOK IN THE CAR, AND NOTIFIED ME YESTERDAY, JAN, 19, 2006, THAT THEY RAN TESTS AND FIND NOTHING WRONG WITH THE CAR. *JB
