Terribly annoying door seal squeaks. I bought used at 830 miles. Took it back to dealer, West Point Lincoln, I10 and Kirkwood, Houston Texas and they did nothing. They said that it was normal. I am 83 years old and have owned many cars and never have I experienced such a noisy car. These squeaks are not normal. I read online that there is a TSB by Lincoln in regards to this problem but cannot find it. The TSB may actually be for a different model year but I just do not know. This is a very expensive car and should not have this problem. In fact my previous car was a 2010 Mercury Milan Hybrid and it was a very quiet riding car. In all respects it was a better car than this Lincoln. This Lincoln rides like a log wagon and it may be that body vibration, possibly caused by the very stiff 245/45 tires and the fact that the suspension is tuned for sports drivers is contributing to the problem. There are 3 settings for the suspension, sport, normal and luxury. The ride is better in the normal mode than in the luxury mode. I do not feel that I should have to spend $1000 on new tires to find out whether this is the problem ie causing body vibration thereby causing the doors to vibrate and the seals to squeak.
