Brakes all 21 →
The brakes keep failing on my 09 Lincoln mks. It has happen 4 times. Each time 4 different shops said the brake booster, abs system or master cylinder is bad. Have replaced each time and it will last 6 months and it the brakes will go bad again. A few times I was in traffic and couldn't stop until the last minute luckily I haven't ran into anyone yet . That's a very scary situation. Yes I have took to a dealer and independent service centers. No it haven't been inspected by manufacture no more than the dealership I got it from. No warnings or anything other than the brake paddle going all the way to then floor. I've also had problems with the sway bar. They have been replaced twice. I have been on many forums and even people I have ran into say their Lincoln is doing the same exact thing. Please we need answers
Brake pedal when coming to stop sometimes goes all way to floor. When sitting at ideal speed the brake pedal will go all way to floor. This has been a problem for the past year and reported to Lincoln dealer for warranty work under a seven year warranty. Car accelerates when brakes depressed when coming to stop and foot is on brakes and brake pedal is depressed and edge of foot also hits accelerates. Dealer had auto from late July 2015 till jan. 5, 2016. Problem still exists as of jan. 5 2016 but dealer states that it is my fault, took to another dealer and the service guy said the reason the brake pedal goes to floor is that Lincoln has what he called a pass through brake system. When car is not running the brake pedal is solid and will not go to floor. While I took car to dealer for this problem in July 2015 it has been a problem for several years but keeps getting worse. …

Speed control & acceleration
Tss/oss failure. While driving the vehicle on the highway, the vehicle suddenly lost power and I was unable to accelerate. I continued to press the accelerator and the vehicles RPM's increased, but the vehicle began to slow down. Then the transmission slammed into gear and made the vehicle jerk. The engine light, a service advanced trac message appeared, and the wrench light came on. I had the vehicle connected to a computer and gave the p7020 and p0722 fault code.
Accelerator pedal jammed and engine was revving high at 5000 , I have press hard on the brake to slow down to avoid hitting other cars while trying to pull away same way like the previous incident that happens 7 months earlier. I then disengaged the transmission to neutral to be able to cut off the engine , wait for 10 and shake the gas pedal , before I cranked up and continued to go on .
