Filed Jul 7, 2015 · Acceleration · 58,000 miles · CA

When braking it jerks and shifts into neutral and the engine reeves to 5000+ RPM. After braking and slowing it again shifts back into drive. This only happens when braking or increasing speed. No dash lights illuminate, indicating a problem. Having to slow suddenly in traffic is very dangerous. A ford dealer recommends a new transmission and a transmission shop recommends a new electronic module..this is an intermediate incident problem occurring approximately every two to four weeks. .

Vehicle was started first thing in morning and driven approximately 25' when the transmission seemed to disengage and warning lights came on. Car remained parked for about 30 minutes and a second attempt was made. The car was driven approximately 2 miles when once again the transmission failed to engage and a loss of power was experienced. Following these two incidents with the vehicle I arranged to have the vehicle flat bedded to the local ford dealership where it was determined that the problem was a defective throttle body assembly the vehicle has 68,250 original miles on odometer.

The car was purchased in may of 2011. August 2011, the transmission started to violently jerk and act as if it were in neutral. When gradually applying the breaks, the car would begin to shudder. This would happen only if the engine was warm. By march 2012, the shuddering transmission and jerk was constant. I took it in to be looked at in april of 2012. The alternator was replaced, due to what we thought was a bad battery. The mechanic believed this caused the transmission to jerk. The problem was not solved. June 2012 the transmission was replaced by a ford dealership for 5,000. July 2012 the car went into fail engine safe mode, the codes pointing to the throttle body. A mechanic cleaned the throttle body saying it might solve the problem. 2 days later the car went into fail engine safe mode again with the same codes with an estimate of $900. The car has 72000k on it and has had three major problems in the past couple of months.

Purchased car on 10/3/2011 from drivetime motors. On the way home, car had obvious transmission problems. Took in for service on 10/5/2011, and transmission was replaced. Upon testing, prior to pick up, the mechanic found that transmission to be a bad one. Replaced with another lkq transmission. Picked up car on 10/27/11. On 10/29/2011, the check transmission light alerted in car. Parked car at home. On 10/30/11, drove car 2 miles to church and backed car into parking space along tree line. An hour later, sent child to retrieve an item from the trunk. Child walked around to the trunk and used key fob to open the trunk. As he leaned to remove items from the trunk, car rolled backwards and knocked him down, luckily, car was stopped by tree limbs on ravine of tree line, as child rolled down ravine. Resulting injuries were head contusion, concussion and badly bruised arm and back. Drivetime said they could not find anything wrong with the car, and wanted me to pick up and assume ownership. The car was not running, had no key in the ignition, and no one inside the car. A police report was filed and pictures taken of the gear shift showing the car to be in park. I am not going to reclaim the car, and am afraid that drivetime is going to return this car back to a dealership to sale and endanger someone else's life.

Driving on the highway on february 10, 2011, started to pass a truck and noticed that I was losing power - I looked at the tachometer and noticed the RPM's increasing. I took my foot off the gas and got back into the right lane. As I got further down the interstate, I heard a loud, screaming noise, and I continued to lose power. I pulled onto the shoulder of the road as soon as it was safe (I was on an overpass). The car continued to run but it wouldn't go into gear. I had the car towed to a transmission shop where they checked and replaced the cv axel assembly and replaced the transmission fluid. In march 2011 I noticed the engine seemed to be misfiring so I took it to an auto repair shop where they said the plugs needed replaced and one motor mount was broken and needed replaced. I was leaving for vacation so they said it would be ok to drive to the airport and return and then bring back for repair. I took the car back on tuesday april 5, 2011. While checking the car out, they found the part replaced for the cv axel was once again broken, which they replaced. I picked up the car on friday april 8, 2011. I left the auto repair shop, drove approx 20 miles when I noticed the same problem starting. I returned to the auto repair shop and they said the cv axel problem was again occurring - the splines were broken. Car was taken to the transmission shop where it was found this time to have an internal transmission problem, said the cv axel assembly would be warranty, but it would be approx $4,000 to replace the transmission with a rebuilt one.

My 2005 mercury nontego has 62550 mi on car heard noise in transmission and took to dealership and it needs a new transmission after looking on line numerous poeple have had problems between 54,000 mi and 67000, mi , the transmission needed to be replaced I called ford corporation and they stated because there is no extended warranty on the vechile they can not do anything for me . Speaking with numerous mechanics there is no way a transmission sould go with that kind of milage. Ford corporation said they it is against company policy to give any type of credit for this problem. With so many people having the same problem I would think that ford would step up to the plate. I really think that ford should initiatte a call back on these transmissions, but they said they will not initiate anything unless national higway traffic safetiy and administration itnitalizes the call back. So I am writing in response to their respnse. You would think a corporation like ford would initiate their own call backs with the noted problems, just to save reputations

While driving down the freeway at about 50 MPH I went to accelerate and the transmission sputtered and then tried to downshift but instead locked up and caused the cars front tires to squeal and a rapid slow down. This failure occurs anytime I try to accelerate to pass a vehicle. With careful driving I can minimize it but am not able to accelerate very well. Dealership has told me to replace the transmission at my cost.
