Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“The car turns on and runs but loses power randomly. It either sputters dead or stalls and backfires. When I turn it off and turn it back on it repeats the cycle. I have replaced fuel pumps, throttle body and maf sensors. And still no luck I see on the Lincoln forums that this is a problem not yet recognized by the nhsta or Lincoln.”

NHTSA complaint #10348069, filed 2010-08, 78,000 miles“It was driving fine one day until I went to start it. It said etc engine fail safe mode, check parking brake and something about the gears. It starts sometimes, I've had it shut down while doing 50 MPH and lose steering and bad braking. This is a potential hazard for my newborn in the car. Now it wont start and no one knows what the problem is. How can they sell a car that they cant find out the problem on themselves and sell it?”
