While turning a corner or going up a slight incline I lose power and the pedal becomes unresponsive for a few seconds. Then the car jutts forward and clunks.

Driving car on side street - going about 30 mph and car lost ALL power. Stopped completely in middle of road. No power - would not restart. NO FLASHERS. Since Aviator has "piano keys", the car would not go into Neutral and once we figured how to manually put car in neutral, we could not get the driver's door to close and latch. Car was placed on flatbed wrecker and driver had to tape the door shut for transportation. Luckily this happened during daylight hours and Sherriff's office sent a car to park behind us. Had this happened on my commute to office (at 0500) when it was DARK outside, it could have horrible - NO FLASHERS

My vehicle has 4960 miles and the transmission started to slow down as if I was driving a stick shift car, then 2 or 3 days later began to kick and lose power when increasing speed after a stop sign. Dealer diagnosed an internal failure on the transmission and it needs to be replaced. A couple of times in the morning after starting the vehicle, when putting the reverse gear I had my foot on the brake but the car still moved and the brakes were very stiff, I had to release the brake and apply it again in order to stop the car from moving. The sensors on the rear brake support are extremely sensitive. The car detects a small crack on my driveway and stops abruptly causing my head to bump twice on the headrest, the dealer said it was normal, no defect found. The windshield fluid I thought it was normal in this car to throw a very small amount of liquid compared to my other lincoln mkz, but reading the complaints from other customers I realized that it's not normal.
