Not sure the exact time but within the past year or so my 2005 Ford Five hundred ( purchased new) is going into failsafe mode limited throttle power, very sporadic at first but now happening quite often. If you pull over and shut the car off and restart it clears and drives normal. My daughter was driving it yesterday and it happened 7 times from mall to the house (about 20 miles). Once while she was in heavy traffic driving about 55 mph. Car jerked then started slowing down. This is a safety issue that needs to be looked at. Very dangerous. My mechanic is trouble shooting problem, looking like throttle body or gas pedal. I believe Ford came out with a new throttle body in 2010 to correct the problem (tsb 05-25-13)but will only replace it at their cost if still under warranty, otherwise the cost is on us the consumer. (about a thousand dollars).

I unfortunately own a 05 Ford Five hundred with 95,784 miles on it. The problem started happening about a year ago and at first I thought that it was my foot hitting the gas when I put my foot on the brake. Then I noticed when I would but it in gear it would try to take off on it's own. I finally had enough just last night I was in a drive thru line and I put it in drive from neutral and I came inches from rear ended the person in front of me. Today I'm taking it to the dealership to get fixed hopefully. Not looking forward to paying a $1000 dollars for a common problem. Well Ford you lost me as a buyer.

The vehicle has RPM surges at low speeds either in reverse or forward. I nearly had 3-4 accidents in 2 days because of the issue. The vehicle will actually increase up to 1000 rpms by itself while I have my foot on the brake. As soon as I begin to release pressure off the brake while trying to park or negotiate the vehicle at very low speeds the engine will just take off. The first time I noticed it I was backing out of a parking space and the vehicle took off backward causing me to have to slam the brakes on. I almost hit a woman who was passing on the other side of the lane.

On 7/27/11 car lunged forward and accelerated past normal driving speed. Car has been doing this (lunging) since I purchased the vehicle back in 2008, but has been accelerating on its own for the past 2 months. I have had the car looked at by a mechanic and it was diagnosed with a throttle body defect.

Backing out of the driveway in a 2005 Ford 500 AWD, car stumbles then launched backward violently. Luckily I had my foot on the brake or the car would have kept going. "failsafe engine mode" appears on the dashboard. This has happened several times before. Should be a recall on this car.

The vehicle in question was idling in park. Vehicle was shifted into reverse with the foot on the brake. Once foot was released from the brake the car lunged backward, the tachometer read about 3000 RPM, with no pressure on the gas pedal. Just as quickly pressure was applied to the brake and the car entered "engine failsafe mode" and shut down. Turning the vehicle off and restarting would clear the problem. This has happened 4 more times since the reported incident date, all with the same circumstances. The vehicle had the A/C on and was idling in approximately 90 degree Fahrenheit temperatures with +50% relative humidity.

When stopped at a light or when putting into gear the car will rev real high lunge forward and sometimes die. Then go into "engine fail safe mode" I believe there are others with this same problem if you look at this site (www.facebook.com/pages/Ford-freestyle-500-Mercury-montego-throttle-body-recall/114094741973972?sk=wall) you will see everyone on there is there to discuss this issue.

I just read a report that you were investigating cases of unexpected lunging in 2005-2007 Ford freestyle wagons. I own a 2005 Ford Five hundred and I have had that same situation happen to me on random occasions. I have entered a randomly chosen date below because this has happened only a few times over the last six years.

Defective electronic throttle body (etb) on 2005 Ford 500, freestyle, and Mercury montego. Causes car to move forward or backward in drive or reverse without using any pressure on the gas pedal. Must place foot on the brake to avoid running into something, especially while parking. Ford has a technical service bulletin (tsb 05-25-13) on this but has not notified any owners of vehicles affected to date. It appears that Ford has come up with a new replacement part for the etb unlike the original that was just made available in July 2010. I paid a local Ford dealer $128.08 to have this problem diagnosed and another $615.83 to have it fixed. I was told the etb part number was "5F9Z-9E926-aa". another number for the new etb part on my sales slip dated 07/30/10 was fmc 6F9Z 9E926 a. they called it a kit for the electronic throttle body. The price for the kit was $495.86. Since I have heard of this problem coming up on more than one occasion, I thought I would turn it in for your investigation. Since the affect of the defective etb actually can cause the car to move on its own, forward or reverse, and requires you to use your brakes simultaneously to keep it from hitting adjoining objects, I thought this is a safety hazard that should be addressed on several Ford and Mercury 2005 products, it is not the money, it is the safety issue I am most interested in. To parallel park or get into a parking stall with this problem was a real chore keeping you foot on the brake as you tried to maneuver in and out of a parking space. If you did not hold your foot on the brake, the car would move in its own either in drive or reverse. This is not acceptable and a true safety hazard, but I have not seen the problem on the recall lists for my car or others affected in the Ford tsb. Nor have auto owners been notified by Ford or offered compensation for the expense to have the kit installed.
