My car wouldn't pick up speed then I receive a sudden thrust causing it to have a small jerk then takes off. Recently its been showing a ranch light know for throttle body issues code p2111 and p2104. This causes my car to stall in the middle of traffic especially on the highway which is a huge concern.

The vehicle while in drive or reverse accelerates to almost 2k RPM causing a jerking motion at any time when you turn the steering wheel. Could potentially cause an accident if in traffic and the car jerks forward.

When moving from a standstill I noticed the the automation on my 2005 ford 500 was not changing up to the next gear .I looked at the dashboard and noticed the wrench light was on and at around 25 mile an hour the RPM was around 3500. In addition the car was laboring but when it reached around 40mph it was if whatever was keeping it in low gear just freed up. The car jerked forward and then all was ok. The wrench light is still on and the car repeats this dangerous even teach time I move from a stopped position. It is a very scary event. I will take it to a dealer tomorrow.

I am yet again having throttle body problems with my vehicle. In december 2012, ford issues a statement to customers tellin us to go have the throttle body cleaned, but that did not fix the problem. It put a temporary bandaide on the real problem that ford does not want to take ownership for. Even after I had my vehicle serviced and reprogrammed, it still idles high and jerks. Today the car would not start after a 45min nonstop hwy trip, I cut the engine off once I reached my destination for about 25 minutes, after which I tried to start the car and it failed. After 5 mins, the car started, luckily I made it home, no lights on dash!!! I found out it was the electronic throttle body the first time it wouldn't start, now after a throttle cleaning!!, I am still having all the very same issues. So unsafe and unpredictable....I am scared to drive the car yet again out of fear of being stranded with my children.

At idle at an intersection with foot on the brake when the car lurched forward violently as if someone had stepped on the accelerator. Luckily I was able to react quickly enough to avert hitting a passing car. The engine then felt as if it stalled and the display read "failsafe engine mode" and the wrench light illuminated. I put it in park shut it off and restarted it...functioning fine now. Identical scenario happened 2 weeks prior. This is a severe safety issue and ford should recall this car for this problem.

The transmission on this vehicle ford 500 2005 does not shift properly. As I was driving and trying to switch lanes on 35w in minneapolis the transmission just jerked and no able to go to a higher speed an accelerate accordingly causing vehicle behind mine to almost hit meat aproxi.65-70 miles . The driver was able to avoid hitting me from behind. We were lucky that did not occur other ways it could have created a pile up on the freeway. I have reported this situation to ford dealers but no available response.later on I went to a private car service in my town of mn and was explained that ford knows about this problem,it appears that the transmission housing bends up with increased temperature and causes this failure. I have noticed that this situation does not occur during winter months. It is a safety concern and ford has not responded to this issue, I purchased this vehicle 4 -5 years ago, but not wanting to sell it to avoid someone else to have an accident specifically if children are involved. The repair is expensive and I have driven other ford and mercury of about same years and find out exact problems. Ford should be responsible and pay or help pay for the cost of fixing please help solve this situation.
