I've driven many luxury and near luxury cars in my adult life. This includes several BMW and Mercedes Benz automobiles. The Lincoln LS V8 is, by far, the best driving and best value of any vehicles in it's class at the time. I understand people have had issues with transmissions, coils and electronics. Honestly, I've had all of the coils replaced under a service bulletin. The transmission valve body was also changed under a service bulletin. Other than that, there have been nothing other than normal maintenance items. In over 115K miles, I have only had to put one new set of brakes on the car and 2 sets of tires (I stuck with the Michelin OE because they lasted so long).
I purchased my LS in June of 2009 for $7,000. I am going to give it to the local vo-tech because it has almost no trade in value and I can't imagine what private individual this car would be good for. Almost every month I have owned this car, I have had to repair something electronic. There are more $500 - $1000 gizmos on this thing than you can imagine. I had hoped that I was getting them all repaired and wouldn't have any more problems but I am starting to replace some things a second time. This car is extremely complex. Some of the parts are designed by Jaguar. When luxury features fail, you don't just lose the feature, you lose basic functions.
How are there not more negative reviews? I owned this car until it was 8 years old and sold it. Right around the 80-90K mark, the Transmission gave out. I parked it for several months looking into the problem and found dozens of forums out there with hundreds of people reporting the same problems as mine: loss of 2nd gear and overdrive. I talked to many mechanics and they all had seen plenty of these cars come in because of a poor design by Ford, Lincoln, Mercury. These transmissions were used in the LS, Aviator, Mustang, and several others. The design is 2 servo pistons (steel) that go through the Transmission case which is soft Aluminum. Over time the opening gets bigger, losing 2 gears.
I purchased my car 2 months ago with 80,000 miles on it. The day after I got it, it wouldn't crank. I thought it was the battery. I got a jump and it worked with no problem. It did the same thing the very next day. I tried to get a jump but it wouldn't start. Found out the alternator was bad. I got that fixed. So now I'm noticing that sometimes when I put in in drive, it takes a while to shift and move. I don't know what's going on. I don't know anything about cars but that seems like something dealing with the transmission. After reading some of the other reviews, I'm starting to get worried.
Have put 40000 miles on my LS in 2 years. It is great. Have only had to take it in to have the AC head unit replaced, and then just GTO (gas, tires and oil) for the rest. It still handles great, and i get about 20 MPG driving a mix of city and highway every day. Just a great car.
