“My Lincoln Aviator started making a horrible noise in the rear of the vehicle on the morning of september 4, 2011. My wife took the Aviator to the aaa car care center to find and repair the issue. The aaa certified technician placed the Aviator on the lift and discovered the entire differential unit was hanging freely and literally swinging under the vehicle. After further inspection, the welding that holds the mount to which the differential until is bolted, broke from the frame. …”
NHTSA complaint #10507210, filed 2013-04, 118,000 miles“My 2004 Lincoln Aviator engine has a burnt valve with less than 90k miles on it. Rich morton Lincoln dealership in glen burnie, md says my repair will be $5,400 if I want to fix it, which they do not recommend. I see online that many others have the very same problem with this vehicle. I have also had to tow in my car as several times the gearshift stuck in park and could not be shifted to drive. I spoke with other owners who had the same problem. Also, my tailgate window randomly flies up while driving, just like other owners have reported. …”
NHTSA complaint #10375188, filed 2011-01, 89,500 miles“I purchased an 04 Lincoln Aviator in dec. 2006, in aug. 2007 I noticed it was not running right. It was stalling when accelerating or decelerating. It would sputter like it was out of fuel. The problem worsened for the next 6 wks. No mechanic could tell me what was wrong because the engine light had not come on. In oct. 2007, I was driving on the interstate when my car lost all power for a split second. I took it to the mechanic who could not tell me what was wrong still. Then my check engine light came on and I was told it was a coil pack. …”
NHTSA complaint #10263639, filed 2009-03, 62,500 miles“I recently purchased a 2004 Lincoln Aviator. About a month after I purchased this vehicle it started to develop problems. The rear bearing seal failed and oil is leaking out. The gear shifter on the console is starting to stick and not go into gear. I understand the Aviator is having a lot of problems in these areas. The vehicle only had 79000 miles on it when I purchased it. Ford must have used inferior materials to make the Aviator. Please look into this and if so force ford to recall the Aviator and replace the inferior parts with parts that are safe and reliable.”
NHTSA complaint #10356799, filed 2010-09, 79,000 miles“The back hatch panel cracked was fixed , the steering not right some times its hard to steer. Main problem is cylinder coils going bad alot. Now #8 coil went bad and has been replaced 2times, and its still in the shop they cant find out why it keeps coming up #8 still misfiring .. They think its the head now. I understand Lincoln has had so many problems with this that they have allowed a 10yr. Extended warranty on all the coils. Is this right ? I want Lincoln to do something. I am so mad right now . I will never buy another Lincoln. Help me.”
