- What is wrong
- Ford Motor Company (Ford) is recalling certain model year 2012-2014 Ford Edge and Lincoln MKX vehicles manufactured September 2, 2010, to November 30, 2013; 2013-2014 Ford Taurus and Lincoln MKS vehicles manufactured August 25, 2011, to November 30, 2013; and 2013-2014 Ford Flex and Lincoln MKT vehicles manufactured September 12, 2011, to November 30, 2013. In the affected vehicles, the halfshaft retention circlip may not have been properly installed, and as a result, the halfshaft may move outward and disengage from the linkshaft while driving and without prior warning.
- Risk
- If the halfshaft and linkshaft become disengaged while driving, power will no longer be transmitted to the wheels, increasing the risk of a vehicle crash. Additionally, if the parking brake is not applied before exiting the vehicle, the vehicle may roll away despite the transmission being placed in 'Park', increasing the risk of injury to exiting occupants and bystanders.
- Remedy
- Ford will notify owners, and dealers will inspect the vehicles to make sure that the halfshaft is properly retained. If it is not, dealers will replace the linkshaft and also replace the halfshaft if it shows evidence of spline damage, free of charge. The recall began on August 4, 2014. Owners may contact Ford customer service at 1‑800‑392‑3673. Ford's number for this recall is 14S10.

Entering I-294 express ramp, vehicle was not accelerating beyond 40mph. then as I entered highway it shut down completely. I coasted to the right shoulder. The dash displayed a "low oil pressure" alert. So I did not attempt to restart the car. When I had it towed home, I checked the oil level and it was full. Nothing like this happened before. The vehicle is almost 12 years old with 167,000 miles. Had this happened in traffic on the expy, I could have been creamed by other cars or a truck. I am going to the dealer today to investigate but this seems like an anomaly where the engine shuts down because the computer thinks there is a catastrophic failure that is not really happening.
I am having issues with my touch screen. My screen will go black every other week, for about a day and the the SNYC will update. This time, it’s been over a week, and the screen is still black. I have tried changing fuses to no avail. Also, the rear camera does not work. Along with the blind spot warning or the rear cross traffic warning. How should I proceed? I believe it may be a faulty chip in the computer board.
While leaving out my driveway my brakes went straight to the floor before stopping. After I put the car in park and put my foot on the break again it was hard to push the brake pedal. I also hear air coming from the break pedal area. I had no warning and still do not have any warnings. I’ve noticed after reading a lot of reviews this seem to be a common problem and it’s not safe. Mileage 104,000
