Leaving a grocer at 13:15 on 9/7/2015 started to back out of parking spot when auto suddenly accelerated backward, across the aisle and slammed into parked vehicle with impact sending that auto into a 3rd. Damages to both vehicles. When I went to pull into my original slot to deal with situation, as soon as I removed foot from brake, auto lunged forward at high rate of speed, jumped a 6" landscape curb and plowed into the front end of a cadillac srx causing major damage to that vehicle, still unk total damage to mine. It was a very hot day and the AC was running. No other vehicles were occupied other than mine, and I was sole occupant. My airbag did not deploy and passenger's was not turned on. I did receive a significant bruise on my sternum from the shoulder component of my seat belt. My foot was not on the accelerator for either "lunge". Crashes were witnessed and peoria az police did respond with 2 units. Officers did take information, but when I inquired about incident # for my records officer responded that there would be no report and no citations as it occurred on private property. My insurance carrier was contacted from site, but being a holiday, I was not able to speak with adjuster at that time. Knowing that it was not my actions that caused this incident, I checked the next day and discovered that this identical situation had been under investigation with the federal safety agency at the time I purchased the car on or about 11/16/12 at which a service program to retify was in effect. With my incident though, major damage occurred. Neither at the time of purchase, nor throughout the investigation & tenure of my ownership (current) was I notified of the known safety problem nor it's program to mitigate. Attached aerial photo shows back to back dimension to first impact and back to front dimension of 2nd. I was parked in position of white vehicle.

Tl* the contact owns a 2005 ford five hundred. While driving various speeds, the vehicle suddenly accelerated independently and there was a sudden increase of engine rpms. In addition, the vehicle would suddenly stall and the fail safe engine sensor indicator illuminated on several occasions. The dealer cleaned the throttle body to remedy the failure, but the failure recurred approximately one year later. The manufacturer was notified of the failures, but no solution was offered. The failure mileage was 100,000.

I had previously had problems with unintended acceleration when parked and then putting the car into reverse (automatic transmission). After reading many complaints on your site in which consumers said the throttle body had been diagnosed as causing the problem, I had the dealership replace the throttle body. ( a few months later, ford sent a letter offering to replace the throttle body). Despite having had the dealership replace the throttle body, the car continues to accelerate faster than it should sometimes when put in reverse and I must always be prepared to brake rapidly. If a driver was unaware of the problem or had slow reaction time, a car or person in a parking lot could be hit.

Car was brought in for throttle recall 3/28/13. Upon the return, the car began experiencing erratic surges of RPM/speed. Gears did not shift right with intermittent acceleration until vehicle shut off while driving on highway, barely escaping accident. Vehicle would not start & had to be brought back to dealer. Dealer stated it was a pre-exiting condition despite vehicle not having any prior issues before recall service. Dealer diagnosed & agreed to replace fuel filter. Vehicle restarted, but still with intermittent acceleration and improper gear shift surges at any speed. On 4/6/13, while driving on highway vehicle experienced several engine failures, narrowly escaping accident again. Shortly after while completely stopped, vehicle lunged forward hitting another vehicle from behind, causing severe damage to both bumpers along with engine failure. Car was brought back to dealer once again, and dealer refused to take accountability and re-service, stating it was a pre-existing condition. Unserviced vehicle remains unusable and considered a hazard to drive. Vehicle sits in stadium ford quality auto mall, rutherford nj with no resolve from ford despite numerous complaints.

My car surges. It is mostly at idle speed. It's dangerous. I was at a drive through and a janitor was sweeping. My car surged and I literally stood on the breaks to prevent running over him. At the drive through it surged forward and I had to stand on the breaks to prevent it from ramming into the car ahead. It occurs more when air conditioning is running but will occur without AC on. I the local dealer replaced the throttle body recently but it still surges. It occurs when pulling to a stop at the lights or at the drive through as you slowly move forward. It happens when pulling into a parking spot or when backing up. I've seen news about the problem with the ford escape. My ford 500 is also affected and weighs a whole lot more. If this thing surges forward it could do some serious damage.

On hot days, when backing out of parking spaces, the car has sometimes "surged" meaning that there has been unintended acceleration without the accelerator being pressed at all. I have had to suddenly and firmly put my foot on the brake to prevent the car from hitting other vehicles. This has happened on several occasions in august of 2012. I own a 2006 ford five hundred also and it has had the same problem in the same conditions (filing separate complaint).

The electronic throttle body is bad in majority of vehicles in my class year. This costly repair causes the vehicle to lunge forward while in drive and lunge backwards while in reverse. It is worst when the AC is on,,it causes the vehicle to idle high and low to the point of almost shutting off the vehicle in traffic.

On hot summer days and only on hot summer days when stopped at light or stopped period car begins to surge forward while holding brake. Went asked ford why is this happening they said they don't know. That I should get the throttle body and mass air flow sensor serviced if not done already. I guess it had to be done at 90k but I did not know. Well I did what they said, went home and car is now idling rough went back and they want to charge me another $90 dollars ontop of the $105 they have already charged me for the throttle and mafs. I have almost gotten in numerous accidents because of this but ford doesn't want to acknowledge that this is a problem with this car.

When back up the car accelerates like you are on the gas but the gas pedal is not touch. When the car comes to a stop and the foot is on the brake, once you take the foot off the brake the car accelerates without warning. This has happen if stop at a light, backing out or even while in park the car will just accelerate without warning! My daughter almost hit a couple of people walking in the cross walk and all she did was release the brake to move up after a car turn and accelerated without warning. I have had the car accelerate after just being stop at a light or moving at slow speed without touching the gas, but it does not happen all the time. Last oil change at ford dealership there was nothing wrong with transmission fluid and there were no leaks......
