Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

2006 Lincoln Navigator Owner Comments

  • 74,000 miles


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.

The contact owns a 2006 Lincoln Navigator. While driving at 35 mph, the vehicle stalled without warning. The contact was able to restart the vehicle after several attempts. The contact stated that the issue recurred several times. The vehicle was taken to a dealer where it was diagnosed that the alternator failed. The alternator was replaced, but the failure persisted.

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 definitely has a design issue that impacts safety and they do not want it known.

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.

Navigator 8-cyl

  • 60,000 miles
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.
