While waiting at the light in traffic, my car all of a sudden Accelerated, and decelerates, I have to push hard on the breaks in order for it to not slam into the cars infront of me.. this is really dangerous, from what I have been reading this is a wide spread issue that ford has ignored for years..

Transmission has very hard and delayed upshift and downshift making it difficult to control speed when accelerating and decelerating. Rpm gets stuck around 3000 at lower speeds and upon engaging into gear has made my tires squawk with a sudden lunge in speed and same problem when trying to stop, the car lunges forward. It acts as though it is in neutral but then when it engages into gear sudden changes in speed occur causing rapid acceleration or deceleration. The problem gets worse after the car is up to normal operating temperature. It doesn't occur as often at colder operating temperature. This problem makes it difficult to get back up to safe highway speeds after having to stop for traffic or red lights as well as hard to get up to speed to safely merge into traffic from an on ramp. As far as "when" this happened it is every day as I drive daily.

Received a code stating that I have a faulty PCM. When I drive all the lights come on and the speed gauge shuts down.

(etb) electronic throttle body on my car causes an acceleration that makes the car jerk forward. I've almost hit a wall, and god forbid this happens on the highway I could cause an accident. Its unsafe and should be recalled. Poor design I guess but it's not worth my life. This happened while idling in drive thru when I tried to go forward it idled really high then dropped down. Would bot accelerate afterwards.

I stopped on a city street at stop sign. As I tried to accelerate, but the car would barely move. The throttle control/transmission warning light illuminated on the instrument panel. I turned the car off and let it sit for about 2 to 3 minutes. I started the car up and was able to make it home. I am thankful that this happen on city street and not on the highway. I plan on contacting my ford dealer tomorrow.

Bought the vehicle used in may 2010. Realized early-on that the transmission was not smooth, but willing to settle for less than perfection since it was a 2005 vehicle. In late 2012 or early 2013, I received 'recall' notice that PCM (I.e. - powertrain control module) could need to be reprogrammed due to stalling, herky-jerky transmission, etc. Took car to dealership, they ran diagnostics, charged me $100, and told me that my car wasn't effected because no error codes were noted and check engine light wasn't on. I was not happy, and refused to take my car to the dealership for repair. Problem persisted, until check engine light came on in october 2017 at roughly 125,000 miles. Took to local mechanic, was charged $150 for sensor replacement. Light came back on a day later. Took back, replaced sensor for free (nice!), but light back on a day later. Took to a different mechanic, was charged $250, replaced multiple sensors, light back on the next day. Took back to 2nd mechanic, when they shared with me that it was likely the PCM and the dealership would need to fix. Called dealership 3 days in a row, on hold for nearly an hour the 3rd time, was never connected to a service writer or tech, left 3 voice mails for service manager and was never called back. Researched issue and found the federal safety agency action number pe11018, where ford initiated a customer satisfaction program 12n03 to extend coverage terms of repair of engine idle RPM surge caused by PCM needing reprogramming with software containing updated idle speed control. Per the federal safety agency, symptoms associated with the condition may include check engine light, diagnostic codes (dtcs) p0505, p0506, or p061b. Ford issued bulletin tsb 11-10-21 that included updated powertrain control calibration.

Harsh and delayed shifting. Lunges forward when in drive at stop even with foot on brake, same in reverse. Car shifts fine for first 20-30 minutes then starts to shift hard up and down... Seems to get worse as car gets warmer

At low speeds, when turning and when accelerating from a stop, the car will shake, lunge and then shut off. Sometimes it just shakes and hesitates and then keeps going. Sometimes it takes a while to get it running again. It always happens when the car is in motion. A couple of times this happened, the transmission error codes were displayed. I have had the transmission checked out and it was fine.
