2007 Ford Five Hundred Engine Problems

“After driving half-hour in high-way southward on I-45 in the morning. The car cannot be accelerate at around 40mph when I ramp up to 288, and the auto-lock light turned red. Seconds later, it recovered back. 2 minutes later, it happened again . And again . So I parked it . ~8-hours later, I started it and the auto-lock light red again. Seconds later, the engine stopped when I back the car. I stepped on gas-pedal when I tried 3rd time, and the car moved and the auto-lock light kept red. …”

“I put my car in reverse to back into a parking space and the car engine accelerate as if it I was on the gas pedal going 50, except I was on the brake. If I am sitting at a red light the car engine accelerate I noticed that the RPM needle will go up to 3 sometime 4 if I am not careful to keep control of the car it will take off so I have to be careful to keep my foot on the brakes.”

“The car will surge when you put it in gear. Does it in drive and reverse. I have to keep my foot on the brake until I am away from a car or building as it will jump into them. I never know when its going to do it. I estimated when it started and is still doing it.”

“The car surges while sitting at a stop light or stop sign also while going slow backing out of garage or driving slow in a parking lot. I am afraid I will hit some or someone when car is surging the tach will jump to 2000 or more rpms while sitting or going slow..something needs to be done !!!”

“Vehicle surges when you let off the brake. This started shortly after we purchased the car a couple years ago. They either serviced or replaced the throttle body and that worked for about 6 months or so. Now the car shakes really bad anytime we have to stop and have to keep foot on the brake really hard, sometimes the car dies during this too as well as going from reverse to drive. As soon as you let off the brake the car accelerates, can make it up to almost 40 MPH without even touching the gas. It runs horribly in the heat too. …”
