The fail safe engine light comes on when driving at any speed or when the fuel gage gets low. I have to turn my truck off, wait a few minutes , then turn it back on for it to cooperate correctly. While the light is on it drives sluggishly.

Latest Mark LT engine complaints
During a 100k mile tune up, I attempted to change spark plugs. Out of 3 plugs, 2 broke off in engine block. The truck was then taken to a mechanic who broke off 3 more. They told me that ford is very aware of the problem and would not do anything about it. It cost me $800 to have spark plugs removed. Now it appears that a part of the old plug broke off into the cylinder head, not removed by original shop, causing more damage that is currently being looked at by another shop.
The engine stop running sometimes. It says "engine fail safe mode" need to completely stop and restart the engine.. Then okay.. It happens not only once but few times already..It happens when the car is in motion..Running around 40 to 60 miles mph.
In 2012, we bought a used mark lt with 60k miles. The vehicle since stalled twice after reaching 100k+ miles and draining two battery, shutting down the engine without warning at a low speed and while trying to turn. This rendered the brakes and power steering useless - we just barely avoided frontal collision with street signs and a bridge as well as almost being rear-ended by driver behind us. Fortunately, both were at low speed and on local rural roads. Also, the vehicle has began hesitating when accelerating...

mostly @ 45-50 mph. The dealership could not re-create issues after first incident and the diagnostics did not show any error codes. Ford issued tsb's in 2008 describing " the engine problems are the result of defects in the following vehicle systems and components: ...Powertrain control module (pcm), ...Transmission control module (tcm, ...Electronic throttle control (etc) and/or the throttle body assembly" which can lead to the following performance and safety issues " acceleration hesitation, loss of revolutions per minute, stalling, loss of power (incl. Loss of power at high rate of speed), sudden and intermittent deceleration and other similar and potentially life threatening malfunctions." Several complaints have been made directly to nhtsa. It is irresponsible that the oem is allowed to continue with this practice in the name of profit and is not required rectify the defects immediately and continues placing customers in danger. The recent gm case should have taught us all a lesson.

While traveling on highway i35 and going 70mph, the vehicle turned off and slowing traffic going 65 to 70 behind me. The error code was engine on safe mode. *Tr
Tl* the contact owns a 2006 lincoln mark lt. While driving at approximately 60 mph, the vehicle stalled and the engine fail safe mode warning light illuminated.

The manufacturer was notified of the failure. The approximate failure mileage was 42,000.
Unable to do standard maintenance by replacing 100,000 spark plugs early. Took the vehicle to the ford dealer, they advised me $1000 if they did not break any plugs. After refusing the repair and paying $150 for diagnosis I magically have a broken plug. Why has this not been escalated to a recall it is obvious that ford has a problem they refuse to address. This minor repair will now be over $1500. Should we buy imported vehicles, that you can put plugs in for $100? *Tr

Lincoln mark lt 2006. As my father proceeded down his drive-way stopping in front of his garage the truck suddenly accelerated in excess of 40 miles an hour. The truck went through the garage door hitting his cadillac escalade, and pushing the escalade through the north wall of his garage. Estimated damage to garage, lincoln, and escalade exceeds $30,000.00. Neither airbag deployed, and the only thing that saved him from going all the way through the garage was that the escalade took the force of the collision....

Previously, my father had owned a ford f150, and he also had unexplained acceleration that caused damage. Previous to the date of this accident my sister had borrowed the truck and when she slipped it into reverse the truck started to burn rubber as she was just trying to back out of her driveway. My oldest brother drove it last week in lynnwood, washington at noon with my father to go to lunch, and was stopped at a light, the truck he told me just accelerated when he had his foot on the brake. Mt other brother had a similar experience when he and my father took a trip together. Ford/lincoln has a serious problem, and you people seem to care less about addressing it. I have owned 1 ford in my life, which I purchased at wilson ford in 1987. The first year it was in the shop 21 times because of stalling at speeds over 30 miles an hour. My pregnant wife ended up crashing through a store front costing me and my insurance company 10,000's of dollars, not to mention almost my babies life. I was extremely interested in reading the other complaints about ford 150's as it reminded me of what the service manager at wilson told me in all honestly. He said the manufacturer in 1987 had not even begun to correct the problems with the 1985 models. You have a problem that is getting worse. *Jb
