I was driving at 45 mph and applied the brake to stop. The engine revved to 2,000 rpm. I was able to stop with very hard braking using both feet. The engine continue revving at 2,000 rpm even after the car had stopped. I placed the transmission in neutral and the engine revved even faster. The engine did not slow down until until I turned off the ignition. After leaving the engine off for around two minutes, I restarted the engine and it resumed running at around 500 rpm. My 23 year old son was seated next to me and verrified that nothing was touching the accelerator while the engine was revving at 2,000 rpm and that both of my feet were on the brake. The engine has revved when I applied the brake at least seven other times; however, the revving stopped after one or two seconds. I have taken the car to a Ford dealer three times for this problem; however, they have not been able to find the cause of the problem.
Tl-the contact owns a 2009 Mercury Grand Marquis. The contact stated that after filling the fuel, she could smell fuel odors inside the vehicle and the after filling the fuel, the fuel would dissipate to half of a tank within twenty minutes of driving. The dealer diagnosed that the fuel line, the fuel pump, and the fuel seal needed to be replaced. The vehicle was repaired. However, the failure recurred. The manufacturer was not notified of the failure. The approximate failure mileage was 35,000. Ne.
I noticed something hanging down from the bottom of the vehicle and on inspection determined it to be a fuel tank support strap. I took the vehicle to my mechanic for further inspection and when he put the vehicle on a lift one of the two support straps had corroded completely in two and the other strap was ly corroded nearly as bad. If the second strap had also broken and allowed the fuel tank to drop and drag on the pavement there could have been a severe fire. I had my mechanic replace both straps immediately today 11-2-16.
