Automatic Transmission Column Shift problems of the 2004 Ford F-150

My 2004 Ford f150 was parked in my driveway in park with the engine running and ac on max. I left it running while I unloaded the back seat of several items. I then closed the doors and proceeded to unload 4 cases of water from the bed of the truck. I made 5 trips from the truck to the house and when I returned and put the tailgate back up my truck took off towards my house and impacted the brick wall of the gararge (approx 20 to 25 foot distance). I tried to run from the back and open the door and apply the brake but the truck hit the house as I got the door open. The shifter was still in park. I applyed the brake and put it in reverse and moved it back to reveal the damage. My wife and I tested this afterwards to attempt to duplicate this without being able to reproduce it. My house and the truck are damaged and I feel that this has the potential to really hurt someone. After being told of this site by my insurance company I see that this has happened to other people and one has almost an identical story. See complaint 10081205. I have taken the vehicle to the dealership and have not been given any information yet.

On 3 different occasions,vehicle was parked in park with engine running,and truck began to move. Third time was undable to catch it and totaled the truck. Vehicle was only 4 months old.

The vehicle was parked in our driveway and left running. We had 3 coolers in the back seat, so we left it running with the air on. We had driven approximately 300 miles total that day with the air conditioning on high. We unloaded the coolers 1 at a time. This took approximately 30 minutes. We were standing in our kitchen when all of a sudden something smashed into the house and then we see our vehicle "driving" by the window up our driveway. It slid along the house and hit the garage (garage is detached). My husband jumped in the vehicle and put it in reverse and turned it off before it went through the garage. It had hit the center pole, and was stopped by that. There was no one outside when this occurred. We contacted the Ford dealer and were told it was impossible for the vehicle to come out of park by itself. I have been researching this, and found that Ford has had this problem in the past, so I think it is possible. There is no other explanation for this happening. There was no one around outside, and we were in the house. The vehicle had been sitting in the driveway for over 30 minutes and we had been in it 4 different times (in the back seat) unloading stuff, so there is no way it was not in park. We tested this too, if you leave it in drive, as soon as you step off the brake it rolls forward right away. We also do not believe it was a "prank" by anyone, as there was no one around outside and my husbands wallet was on the dash and my purse was in the passanger seat and both were not touched. I am very concerned that there is something wrong with the vehicle, but like I said they keep insisting it isn't possible. Which is not true, as I see they have had this problem in the past. I'm not sure what else I can do at this point since the Ford dealer won't even acknowledge that this could be a problem.
