I purchased this vehicle as a certified used vehicle. It had an extended warranty. Once it expired I've experienced every single complaint people have stated online about this vehicle. As of today (12/02/13) it still has only 74,000 miles on it and the latest problem is the transmission needs to be replaced but they don't know why. I am a stay at home mom and wear-and-tear on it is very minimal (grocery shopping, to and from school, etc.). I have never had so many problems on a "so called" luxury vehicle before! I've had bad coils in cylinders 3, 4, 5 (twice), and 7 replaced under Lincoln's recall. The tailgate panel cracked (just like all the other people who own this vehicle and the Mountaineer have complained about), but they won't fix it. In addition, a white plastic piece fell out of the top half of the tailgate and now it will not close anymore therefore I can no longer take it through car washes. The bracket for the sun visor on my passenger side completely deteriorated and caused the visor to suddenly dangle from the roof of my car while driving. Now, I cannot flip it up and it causes a blind spot. There is also something faulty with the brake light switch which drains my battery on a regular basis and I have to have my jumped. The brake light switch has been replaced 3 times now because it is has shorted out. To complicate matters, every time I take the car to the dealership for these repairs, they insist on doing a "diagnostics check" and every time they want to charge a fee for this service. Every time the price is different...some times its $50, sometimes its $100. This vehicle is a lemon and I will never buy a Ford/Lincoln/Mercury again.

  • 126,225 miles
The cars check engine light came on in 4-20-07 just over 50,000 miles. We were told by Ford two cylinder heads7 &8 had issues and would require a $5900 O.H. they did offer us $1500 towards the engine. We learned latter, Ford had a inter-office bulletin about this problem as did all-data. Now at 126,00 we will have to have the engine overhauled. Ford should be mandated to cover the full cost of these repairs. They have known about this issue since 2004.

1 year after purchase at 52,000 -replaced coils (recalled), brake switch, cost just to lead and find issues after full service maintenance, $1500. 2 yrs in, transmission due to thing that is attached and looks like a brain plate to the transmission, (sms pack)still owing plus now, upcoming on latest transmission/computer/ at 84,000 :( S car has taken me completely upside down and in the hole owing $12,000 + $3000 for newest repair. Just got car back and now it feels like there is a potential small delay and wants to jump in the middle of traffic which I just experienced yesterday. Why is this car still on the road and not recalled. The problems go on and on and on. I emailed Ford and was basically told to take the car into their dealership where I can be robbed even further. Sad!! these are only a small fraction of links that are out there due to Lincoln having known issues. I spoke with a car salesman this last week and he has a 2005 Aviator and just replaced the whole transmission at 92,000 miles. www.automotiveforums.com/T936173-possible_solution_for_the_common_lincoln_ls_trans_problems.html VIN.centralclearinghouse.com/central/VIN.nsf/0/22bff5be198030B78825777D002F814D repairpal.com/shift-lever-stuck-in-drive-
