“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 #10993329, filed 2017-06, 167,786 miles“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! …”
NHTSA complaint #10554425, filed 2013-12, 72,614 miles“2004 Lincoln Aviator gears were slipping and would not shift; had it checked and was told the transmission was failing. 2 days later we had to have it towed to the shop because it was stuck in neutral . Had to replace the transmission at only 63,000 miles. Never had a transmission fail with only 63k miles, all preventative maintenance is kept up on our vehicle. Loud noise at startup and A/C does not work, I believe it is the clutch. No help from ford even though there are multiple complaints of transmission/power train problems. …”
NHTSA complaint #10419511, filed 2011-08, 63,000 miles“I tried to pull off at a very busy intersection and nothing. I came very close to getting into a crash. I am now told from the dealership that I need a new transmission and transfer case. I've taken very good care of my vehicle since I purchase my 2004 Lincoln Aviator lux with 80,000 miles on it and always had it serviced at the dealership. I thought I was making a good decision when purchasing a Lincoln. I'm a single parent and wanted a reliable vehicle. Worst decision I ever made!!! First it started with the gear shift getting stuck and needing replaced. Then I had to replace all coil packs. …”
