My 2007 Lincoln MKX was in Drive with the brake depressed waiting to back up into a traffic lane from an angled parking space in front of a small shop in our historic downtown area. Suddenly, the vehicle accelerated forward at a high rate of speed jumping the shallow curb and slamming into the cement foundation of the store. Continuing to depress the brakes made no difference in stopping the jarring unintended forward motion. The speed moving forward was so high that in the 10-12 feet from the curb to the store entrance the impact demolished the entire front of the vehicle even bending the front axels. The airbags did not deploy at all. The witness interviewed, reported loud screeching tires as her back was to the scene during the collision. Local PD, EMS and Fire all responded, with a full police report filed. It was extremely fortunate no person was either on the sidewalk or in the entrance to the storefront. My injuries included severe bruising to the right side of my neck, as well as a hematoma on my right tibia and an oblique fracture to bones in my right foot. There were no passengers in the car with me. The accident, and extreme concern over the malfunction of the vehicle allowing it to take control away from myself as the driver, has been reported to Ford Lincoln and a claim number established. My insurance company took possession of the vehicle from the tow lot after three days after determining it was a total loss. To reiterate, there was no warning at all before the incident. I was simply waiting for traffic to clear, so I could put the vehicle from Drive into Reverse and pull out of the parking space.

The contact owns a 2007 Lincoln Mkx. While driving at approximately 55 mph, the accelerator pedal was depressed but the vehicle failed to accelerate. As a result, the speed decreased causing the two vehicles driving behind the contact to crash into each other. The contact was not involved in the crash. A police report was filed and no injuries were reported. The failure recurred numerous times. The vehicle was taken to a dealer where it was diagnosed that the control solenoid needed to be replaced. The vehicle was repaired, but the failure persisted. The manufacturer was not made aware of the failure. The failure mileage was approximately 49,136.

My wife's car stopped moving in an intersection, doing some research on this I have found that there is a defect in the transmission output speed sensor. It causes the computer to not know how fast the car is moving and kills the exceleration of the vehicle. I took the vehicle to a Ford Lincoln dealer and although when looking on the internet this issue is well documented, the dealer gave me the impression that they were not aware of any such problems.

I was driving out of the parking lot suddenly anxious about the gas pedal because however hard I pressed it, the car wouldn't move ahead. I managed to get onto the main road with the emergency wrench coming up along with the driver airbag and zero mileage for the car indicating. However, this was lucky because it didn't happen on highway, I was extremely stressed out standing in the lane to turn to highway. I changed my mind, turned around, and returned to the parking lot at a crawl. I understand now that this is a common issue with the Lincoln Mkx 2007 due to the fact that the Ford opened a claim website related to just this problem. No wonder recently I have been bombarded with the letters to renew my factory warranty as soon as possible. Just as I paid off my car last January, it started breaking on me. Is it the reason why you make your cars to last only during the period of the 5-year factory warranty?!now, to change sensor on the pedal cost 400+ and I am afraid to drive Lincoln Mkx because of this safety issue.

Output speed sensor failure, due to a known tendency to short in the sensor wiring for 2007 Lincoln Mkx and Ford edge vehicles. This will result in the wrench icon to light up on dash and vehicle will speedometer will be stuck at 0. the worst and most dangerous symptom, however, is that the vehicle will then be stuck in 5th gear, resulting in extremely slow acceleration from a stop or low speeds, especially on inclines. If you put the vehicle in park and then shift into drive, it will result in a heavy 'lurch' and very loud thud, that feels like the vehicle is being rear ended. Driving a bit in reverse, then powering off and restarting seems to eventually clear this state and return to normal operation, until it happens again. Has happened 3 times in the last 2 days. The first time it happened, it nearly caused an accident as I went to change lanes on the freeway after slowing down in heavy traffic. This can also be extremely dangerous making right turns with oncoming traffic, or left turns with approaching traffic. This is a known defect, due to poor sensor wiring\housing, and poses a definite safety threat. This should qualify for a recall.
