Takata recall. At a slow speed, with the foot on the brake, vehicle accelerates. Speed is generally under 10 MPH and has happened during turning...either left or right. Specifically: it happened once turning left into a parking spot; it happened making a slow right hand turn on a street; it happened again during a left hand turn into a parking garage. We took it to a shop and the mechanic drove it. It happened to him as well, but I don't have the specifics for the one incident, but he also experienced the brakes not engaging normally to the point where he had to push extremely hard on the brake to stop the vehicle. The vehicle is still with the mechanic. I'm not sure if he's finding the exact cause of the problem. The master cylinder has been replace so far, but 3 of the 5 or 6 incidents occurred afterwards. We did contact the local lincoln dealership service department and they told us they have never heard of a similar incident. We just purchased the vehicle second hand and have only owned it for 2 weeks. It started the day after purchase. It's dangerous and we don't know where to turn since we bought the vehicle "as is". Will follow up with the mechanic tomorrow, 05/13/2019.

My 2007 lincoln navigator may need rail cross-over hose because it contains weak areas. The hose may crack, which could cause a fuel odor and/or fuel leak. This is what I'm smelling outside of my truck.

While making a left turn the engine shut off and barley got through the turn without getting hit by on coming traffic. Vehicle was towed to closest garage and checked out. The wires on the fuel pump in the tank were melted. Called lincoln and they said they had no recalls and could not do anything about it, at that temperature don't know why it didn't explode or start a fire since it is sitting in the gas tank..

My 2007 lincoln navigator ultimate 4x4 engine stopped running suddenly like it ran out of gas. There was a half a tank of gas in the vehicle. The vehicle would crank and crank but would not start. I troubleshooted the issue to a failed fuel pump. When I pulled the fuel pump out of the fuel tank I noticed that the wiring going to the negative side of the pump was melted. This is extremely dangerous that the pump was submerged in gasoline but it got hot enough to melt the plastic on the pump and wiring. There should be a recall for this issue.
