Front differential leaking oil

For some 4 years now our car has gone into a limp mode while being driven at highway speeds, over bridges, and along dark roadways. The check engine wrench lights up when the car goes into this mode. Unannounced, the sudden and immediate slowing of the car leaves it unsafe to driver, passengers, and others on the road who find themselves behind a fast moving car that suddenly and without notice drastically slows down on its own. It is an uncontrollable unsafe and hazardous creeping condition. The car restarts and drives after being placed in park and shut down. The car then drives normally until the next limp situation. Once the car is turned off and restarted however the check engine wrench clears from display screen, and the code itself clears from the pcm. This has made the intermittent events impossible to catch upon being diagnosed by the dealer. We finally had to drive with our code diagnostic device to try and catch the problem as and when it suddenly arose in traffic. Last week the problem occurred again. We were able to get to the side of the highway and plug in the diagnostic device and pull a single code; DTC P2111. Upon researching the code we found that this unsafe problem as been known to Ford for sometime, but we were not in that group of owners who were sent letters explaining the extended warranty program put into place to correct this situation. That Customer Satisfaction Program, 13N03, extended the warranty period to 10 yrs from in-service and 1500 miles. Our vehicle, a 2013 Lincoln Mks with 110800 mis., is clearly is being affected by the throttle stuck open/closed defect (P2111), and, clearly falls within the extended warranty coverage period. We have tried to get Ford to handle our P2111 Code problem as it has corrected others it acknowledged and repaired, but Ford declined. Ford told us that since NHTSA had not assigned coverage to our VIN#, so it cannot come under the program. We are asking that our car be placed in the program and repaired.

While servicing my Lincoln Mks with an oil change, I noticed a brownish fluid leaking from my inner front wheel area. I had no idea what that fluid was for, so I googled it and it said it could be from a defective ptu on my AWD Lincoln Mks. At 34,983 miles, I took it to my Lincoln dealership for service, and it was in fact a defective ptu. The Mks was a certified vehicle so the costly repair was covered under the warranty. However the replacement unit will also fail as Ford states that it is lifetime gear fluid and it does not need flushed or changed. The ptu is located directly near the exhaust system and that is what causes the fluid to overheat and to break down causing the gears to fail in the unit. Other countries have actually an adapted version of that ptu with a drain plug for regular flush and fill maintenance but not vehicles in the us. Consumers have made videos of how they have installed their own drain system on the ptu to correct this issue of not being able to drain and replace the degraded and useless fluid in the unit. This is a severe problem that needs handled.

While driving the 2013 Mks at 70 mph on a 3 lane highway the power cut out and the car began to decelerate. I was able to guide the car from far left lane across 2 additional lanes to shoulder of the road with no power, we coasted. Luckily there was light traffic at the time. The car would not restart and a tow truck was called. When our son picked us up roadside he conveyed that the identical problem happened to him in the car. This was approximately a month earlier. I am sure you understand that this created an extremely unsafe condition for us and other drivers. I have contacted the dealership that sold us the car.

The vehicle lost all ability to accelerate while operating at approximately 65 mph on an interstate highway. This forced the operator to coast the vehicle to the shoulder of the highway while navigating through traffic. The powertrain malfunction/reduced power (rtt) wrench symbol illuminated in addition to the service engine soon light. Before the tow truck arrived the operator attempted to move the vehicle under its own power every 15 minutes. Within approximately 40 minutes the vehicle responded to the accelerator and was driven to the operator's residence. The service technician diagnosed that the throttle body lost electrical power forcing a fail safe mode that disconnected the accelerator control.
