Problems with 2006 Ford Expedition ENGINE

On average, the 2006 Ford Expedition starts to “feel” problems with the ENGINE and its various aspects after 110 039 miles.

Recently reported ENGINE problems on 2006 Ford Expedition

Engine went in to fail safe mode and stalled while coasting to pull off. put in neutral shut off key and then restarted. no more problem..until a year later. fail safe then stall. restarted and check engine light on. after 10 miles fail safe and stall. restarted check engine light on took to dealer. diagnosed as throttle body $650 repair. obviously; i am not the first victim! shame on you ford for not stepping up and taking care of your customers and replacing the throttle bodies. to consumers..fail safe doesn't mean safe to keep driving, it is designed to keep the engine running just long enough to maintain power steering and brakes while you pull over. good luck! *tr

Engine lost throttle control, reduced to idle and then stalled. i coasted off road, and restarted after 2 attempts. *tr

on 1/9/2013, i was driving at approx. 35 mph when the engine turned itself off. i attempted restarting the engine to no avail. i coasted to the side of the road where the engine still would not start. after waiting about five minutes, i was able to restart the engine. the car seemed to run slowly on the way back home. the next time i drove the car, it seemed to run normally. on 2/12/2013, my wife was driving the car at 25 mph when the engine died again. she had to coast to the side of the road & wait to restart the car. she slowly drove back home with the vehicle. next time the car was taken out, it ran normally. i am concerned that this problem could occur on the interstate highways at a higher speed & the result could have been vastly different. *tr

We were experiencing stalls and overall sluggishness and took it to a mechanic who told us we needed a tune up. my husband usually does minor upkeep, thanked the man and was about to take our truck home when the mechanic informed us that the plugs were a bear to change since we would need a special tool and chances are, the plugs would break off. we were skeptical but trusted him to do the job. it cost so much and took so long, we bought a beater car in the interim so we could get to work! and it cost over $1000...for a tune up!!! it looks like ford knows full well about this built in money maker since i see we are in good company with many owners complaining about the exact same issue. shame on ford.

Twice in last week, driving at slow speed and "engine fail safe mode" light comes on. lost power, braking, and steering. forced to put car in neutral while car was rolling to restart. rolled right thru stop sign. restarted fine, luckily. in second event, almost got hit when turning left across oncoming traffic! started turn and couldn't stop turn due to loss of braking. fortunately, first time i tried the restart in neutral and it worked, otherwise i would have been hit in second event or hit something since i couldn't steer. *tr

I was driving on a two lane highway, fm 185. i was driving northeast while the other driver was somewhat stopped heading west, trying to turn south onto cattle drive. the other driver was stopped at an intersection awaiting to turn left. the other driver turned left in front of me as i was headed straight. the initial impact was driver's front side and then down the drivers side door. we hit, and then my vehicle did a 180 degree turn which turned my vehicle around facing my initial path of direction. my airbags did not deploy. i had curtain side airbags, driver, and passenger air bags as well. the airbags of the car causing the accident did deploy. *tr

While traveling on the highway at approximately 75 mph in a 2006 ford expedition, the vehicle's engine suddenly and without warning shut down. due to the loss of power, the steering and brakes were extremely difficult to control. the vehicle coasted on the highway until i was safely able to direct the vehicle to the side of the roadway. after stopping and parking the vehicle safely, i was able to restart the vehicle without further incident. this occured a total of three times in months that followed. i took the vehicle to a ford dealership and they could not find a problem with the vehicle. after researching the incident online, i learned that the throttle control switch may have been the cause of the problem. i notified the dealership of my research and they did not agree. i replaced the switch on my own and i have not encountered any additional engine failures since. *tr

Engine shuts off while driving and shows 'engine fail safe mode'. this has happened 6 times since i bought the vehicle in march 2012 (i've had the vehicle a little over a year now). it has happened in 1) a restaurant parking lot while on vacation; 2) in a parking garage at work; 3) in a store parking lot; 4) in a store parking lot; 5) on a road; 6) in a store parking lot. (#5/#6 just happened yesterday to my wife while shopping with our 3yr. old son). this is a serious safety issue because it can happen any time, anywhere, without warning. i have contacted ford and of course they say they are not aware of the problem - even though i have found hundreds of complaints on various online forums and right here on the nhtsa website. it seems (from my research online) that the problem can be fixed by replacing the throttle body and tps - which is a costly repair for which i do not have the money (after just buying new tires in addition to a separate $500 repair). ford needs to recall and fix this issue before someone is injured or killed!! *tr

Engine was losing power under load (only while accelerating). no check engine light ever came on. at 88,000 miles figured that not only will i replace all 8 spark plugs, but would replace all 8 coil packs as well. upon removal on the spark plugs, 1 spark plug broke (so far) leaving the bottom piece inside the head. ford knows about this problem, as it can lead many like myself with an outrageous expense to properly remove the broken spark plug and can in the long run damage the aluminum head too. they are motor craft platinum (ceramic inside) spark plugs. napa sells a tool to extract the broke plug out. why in the world this is allowed to continue on without a recall is beyond me. ford knows about these issues and should have a massive recall for the any vehicle that contains these spark plugs, like my 2006 model with a 5.3l does. i have called ford and filed a former complaint and many others need to do so as well. i am also going to file a complaint with the bbb, as i spent a huge chunk of change and properly maintain my vehicle on a daily basis. if my truck has to go into a repair shop to have this plug removed, i will be very disappointed in ford's customer service. i have 4 fords today.......nothing has ever been this costly! i have a 71 bronco, 98 explorer, 01 ranger, and 06 expedition. i guess this will determine if i will stay as a ford owner in the future. *tr

Tl* the contact owns a 2006 ford expedition. the contact stated that while the brakes were depressed, the engine safe mode warning light illuminated. the vehicle was not taken to the dealer. the manufacturer was contacted but the vehicle was not repaired. the failure and current mileages were 79,000.

This is the 1st complaint on this issue. while driving down the road, the engine fail safe mode engages, the engine loses power, for no apparent reason. you pull over if you can. put the vehicle in park. turn everything off. shut off engine. restart and if you are lucky, put it in drive and continue on. this is very dangerous, if someone is tailgating you and this happens, they could rear end your vehicle and people could have a major accident and die. this has happened 4 times now. there's are hundreds of complaints on this issue online. thank you. *tr

Engine shut down at highway speed. loss of power steering and power brakes. was able to coast to emergency lane then restart car. happened two additional times. took to shop where the throttle body was replaced. no issues since then (~ 1 year ago). sounds like manufacturer defect. this is a safety issue. *tr

My 2006 ford expedition has shut off multiple times since the summer of 2010. it was serviced in the summer of 2010 and ran fine for a while. in 2011, it started cutting off at random times. i could be at a stop light, intersection, driving, or turning the corner. i have had the vehicle tested about 3 times over the last year and no one can seem to figure out the problem. the scariest incident happened while i was making a left turn at a busy intersection and the vehicle shut off and the power steering went out. i turned on the hazard light, put the car in park and started it very quickly. the vehicle started up with no problem. luckily no one was behind me or coming towards me. this problem needs to be fixed. i have read multiple post about this problem and ford has not recalled the vehicle yet. please help! *tr
