Engine Failure Problems of Lincoln Navigator

I was driving at about 40 mph on a two lane road and my Navigator just shut off. I looked at the instruments and it said engine fail safe mode. I pulled over as best I could and placed the vehicle in park and turned it back on. Luckily I was only about 3 minutes away from home. I read the manual and it mentioned coolant. I checked the coolant but it is completely full. I've been reading about this issue and it seems as if there's a flaw. I've read about how people take their cars in and have different diagnosis and the issue does not get fixed. I will be taking my vehicle in to Ford but I'm worried that I'm going to be charged a lot of money and it may not even repair the issue. There are many complaints about the engine fail safe mode with vehicles shutting off on the highway. I'm afraid to drive my car even after I take it in to Ford. If I'm able to I will upload my bill once I see Ford.

2006 Lincoln Navigator, with just over 100,000 miles on vehicle. Vehicle shut down immediately after giving an engine failed safety mode error on dash. Fortunately my wife was driving in the neighborhood and doing 25 mph. Muscled it over to the side of the road and restarted the vehicle. This is about the 4th time this has happened in the 5 years we have owned the vehicle. The other times the vehicle was being driven around 45 mph on 4 lane highways/roads. We had a 2003 expedition that had the same problem. Ford motor company definately has a design issue that impacts safety and they do not want it known.

The contact owns a 2006 Lincoln Navigator. While driving approximately 45 mph, the engine fail safe mode warning light illuminated and the vehicle stalled. Also, the steering wheel seized and the brakes failed. The vehicle restarted immediately. The failure recurred several times. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure. The approximate failure mileage was 68,000.

Was driving on the highway and the vehicle went into engine failsafe mode. Was able 2 pull over and turn engine off and restart with no prob. This has happened at least 10 more times since always on acceleration luckily I was not in accidents. Most of the shut offs have been in highway driving conditions at speeds over 55 mph. After research seems this is hard 2 diagnose but Ford is aware of this issue. Seems as though it's usually the throttle body but can also be the fuel modulator. Other people have been in accidents I'm just lucky I haven't.

The contact owns a 2006 Lincoln Navigator. The contact stated that the engine fail safe mode warning light illuminated as the vehicle stalled. The vehicle was able to be restarted and began to function normally. The vehicle was not taken to a mechanic and was not repaired. The manufacturer was contacted about the failure. The failure mileage was approximately 140,000.

During normal driving conditions, the car gave in rapid succession a number of warnings and the car began to run rough and shift erratically. One related to the stability control system and the other was a "etc engine failsafe mode". After restarting the car the stability control error persisted. The dealer replaced sensor assembly 6l2z*3c187 for ~ $1000 for the part and labor + the battery and indicated no other codes were stored relating to the fail safe warning. The fail safe warning returned a few weeks later and the dealer was unable to replicate or capture any codes over a 2 day period.

2006 Lincoln Navigator, 60,000 miles on car. Car shut down after giving an engine failed safety mode error on dash while on four lane busy highway traveling 40-45 mph. Coasted to side of road (no berm available). . . Waited 5 minutes. Restarted car and limped into gary yeoman Ford dealer. I was told the throttle control body & motor asy #3l3z*9e926*a was bad and was not covered under the extended warranty I purchased on the car in 2009. Repair bill was $900 out of pocket. Checked online and this is a known issue for Ford expeditions & Lincoln Navigator engines and yet Ford does nothing to fix. Does someone have to die to get Ford to repair these defective parts? nothing more dangerous than a car that shuts down in heavy traffic traveling at high speeds.

1: 10/19/08 I was driving 70+mph and all of sudden car gives an engine failure/safe mode signal which locked wheel, not allowing acceleration. Once able to get to side of the road, I had to try at least 2 times until finally car turned on. It was towed and dealership could not find any problems. 2: 11/16/07 started car drove about 2-3 miles and then when I had to restart the car, it did not come on. It was towed and battery was replaced 3: 7/16/08 turned on car, drove for almost 2miles, stopped at a light and when I had to accelerate, the car gave me a engine failure/safe mode signal. Dealership could not find anything wrong with it.
