Problems with 2012 Ford F-150 POWER TRAIN

While driving on an interstate with two motorcycles in the bed of the trucks, the truck started to shake and vibrate. have since seen this referred to as the shudder that sometimes precedes the limp mode which results in power failure. after changing lanes and monitoring tires on nearby vehicles in motion we confirmed it was not the road. i have since experienced it again but cannot recreate the behavior on demand and it seems to be only on long trips with a load in the truck. *tr

On numerous occasions while accelerating to merge into traffic or to pass a slower vehicle or hard accelerating from a standing stop vehicle shakes and stalls, stays in second gear and has no throttle response, in wet or dry conditions, sometimes completely dying. on one occasion vehicle stalled and died while entering expressway causing me to have to run off road, hitting a sign and dirt bank to avoid approaching semi truck. engine oil is diluted with gas, has burning smell in engine compartment. we are afraid of engine explosion and fire, burning smell is so bad. ford has attempted several fixes, but problem continues, now there is a grinding grunt when going into reverse. *tr

I was merging into traffic on i-10 in florida from an entrance ramp. i was going 55 mph when i had to accelerate in order to merge with traffic. upon attempting to accelerate, the engine lost power and began to shake causing me to have to brake really hard and move to the shoulder of the road so that i wouldn't collide with traffic already moving at 70 mph in the lane i was attempting to merge. this is the first of several incidences in which the vehicle lost power under acceleration. *tr

Tl* the contact owns a 2012 ford f-150. while driving approximately 60 mph with the cruise control activated, the pedal was released and the transmission abruptly down shifted three gears. the contact was able to continue driving after waiting ten seconds. the vehicle was taken to an authorized dealer who advised the contact that the vehicle was functioning as designed. the manufacturer was notified of the problem. the approximate failure mileage was 1,000. updated 9/25/12 *cn updated 10/03/2012 *js

This is in reference to a loss of power while passing in rainy conditions in my 2012 f-150 crew cab 4x4 3.5 v-6 eco boost. after driving at slow speeds (25-35mph) and fairly constant throttle on a 2 lane highway for approximately 30 miles, i attempted to pass a vehicle starting at 50 mph. as soon as i was on boost i experienced a significant loss of power forcing me to take violent evasive maneuvers including full braking and hitting the shoulder, to barely avoid a head-on collision with an oncoming vehicle. as the bed was empty i assumed that i spun the tires on the very wet highway and hit a rev-limiter as it felt like i lost several cylinders. once it returned to 6th gear and about 1500 rpm the engine ran normally. subsequently i have rolled on the throttle slowly when requiring full power in wet conditions. after reading about the other similar issues i realized that i had experienced a problem with the turbocharging system. with this in mind i now regularly go to boost where i don't need the power to remove the condensation from the intercooler when conditions are wet. *tr

Tl* the contact owns a 2012 ford f-150. the contact stated that while driving 55 mph and attempting to accelerate, the vehicle decelerated without warning. the vehicle was taken to the dealer who upgraded the transmission software. the manufacturer was not made aware of the failure. the vehicle was not repaired. the failure mileage was 2000 and the current mileage was 5,000.

Purchased truck new april 2012. while driving on the interstate i tried to accelerate past a slower vehicle. the truck would hardly run, lost power and speed. this is a known problem with ford ecoboost engine. unfortunately i did not do my "homework" on this engine package. many complaints of this problem can be found on the internet. ford motor co. knows and admits that there is a problem with condensation build up in the intake tract of this engine. it has been aproblem from introduction. they still have not found a "fix" for this defect. so far this truck has been to the dealer 2 times for this problem and nothing has worked. this truck is dangerous to myself and my family. if it is raining while driving, it will hardly run. it is unsafe to own or operate. *tr

2012 f150 3.5 ecoboost, on multiple occasions while driving the truck at highway speed, then attempting to accelerate to pass the truck shudders violently and temporarily loses power. the most recent occurrence almost caused an accident. while traveling from a 40 mph zone into a 55 mph zone with closely following traffic the truck began to shudder as described, then lost power completely causing me to coast to a stop. when this happened i was nearly struck from behind, the vehicle would not respond to throttle input and remained idling very roughly. i shut the ignition off, waited a few moments and re-started the engine, then continued home. i am becoming very concerned that these events may cause a crash and someone could be injured or killed. i'm making an appointment with my dealer for service but after reading many forums, i'm not optimistic that the problem will be resolved. *tr

F150 eco boost 2012 will not run right when its damp or raining it shutters and misses while driving it ford has worked on it over and over and it still has the same issues it is a safety issue and they don't care. they tell u when u buy it that it get 22mpg but it really get 12 to 14 mpg this is by far the worst truck i have ever owned. i have contacted ford motor company several times over the past year and they still haven't fixed or addressed this problem. *tr

I've had problems since the first month of purchase, first time it stalled pulling out of a stop sign with my kids in the truck, scared us to death. second time, my wife and i were on the interstate going on vacation driving at night in a steady rain, truck begin to shudder and stalled out, had to pull over about 5 times during a 5 hour trip and sit until it would crank and run again. when i returned i took into ford, they couldn't find any problems, truck kept doing the same in a rain so i took back to dealer and after the third or fourth time they said there is a defect and ford has a new part coming out in october of 2012, ended up getting the part installed in december 2012. truck is doing the same thing, just stalled on me in branson, missouri, i called dealer and corporate ford and get nowhere. i have a complaint file number with ford corporate on this problem but no will help me or offer me a new truck without ecoboost. very frustrating to buy a brand new $57k truck and find out it does not run well in the rain and ford new of this problem when they sold it to me in april 2012. now i find out there is a class action suit started in louisiana and ohio for the eco boost trucks. dont really want to go this route but ford and autonation-cook whitehead ford dealer has given me no choice. we need to all publicly let our dealers know by being on the news or other means so ford will stop selling these vehicles. its not right to treat us this way. *tr

Ford f150 crew cab - lariat - v6 ecoboost engine. problem occurs when not towing, not engaged in 4x4 mode and occurs randomly in wet, damp and dry conditions. driving at highway speeds (60) on a 70 mph highway, tried to accelerate to pass semi truck and truck shuddered and would not accelerate at all. speed dropped dramatically and we were almost hit from behind. only method of getting truck moving was to stop on the side of the highway and let the truck sit, turned off for 2 - 3 minutes. it took 5 or 6 of these stops to get to the nearest ford dealership, where a tsb was referred to and it was suggested by the dealership that we continue on our vacation and stop in tallahassee to have a larger dealership take a look. the tallahassee crew updated the computer and provided a report for bill currie ford in tampa, to install a shield of some sort once we returned, as they did not have the part in stock. bill currie service reported that the shield was already in place when reported a few days later. the truck was taken to bill currie ford a total of 5 times for the same problem with the final time to have a ford tech do the work. the problem persists. overall the truck is less than it was advertised. i got 18.7mpg with my previous 6.2l f150 and i have yet to get more than 17.8 on the ecoboost. around town i also get much lower mileage (11.7mpg as opposed to 14.9 with the 6.2l engine. the shudder/loss of power occurs randomly and has resulted in near crashes at least 5 times in the months since we purchased the truck, all at highway speeds. *tr

In damp conditions the f-150 with the eco boost engine has a severe vibration and loss of power problem when the turbo chargers are called for. in otherwords when you strongly accelerate to get on the highway the truck dies. *tr

While driving my 2012 ford f150 4x4 with the ecoboost motor to work on the garden state parkway i experienced the following issue: after cruising for about 20 miles at 65mpg i attempted a pass of slower moving traffic. the truck accelerated to about 80mph during the pass then suddenly the engine lost power and created an engine breaking situation. the trucks' speed dropped rapidly from 80 to 60mph and i had to abruptly move into the slow lane cutting off other cars to avoid being rear ended. as soon as the power/speed loss occurred the truck began to shake violently for about a minute or two until i eventually slowed to about 50mph. this has happened 2 times since owning the vehicle. the truck has 5000 miles presently and has been back to the ford dealership 3 times for software updates, a catalytic converter replacement, to add an air deflector and it continues to throw codes and turn on the check engine light. i got it back yesterday and the check engine light went on again on my drive home. also mileage seems to becoming progressively worse. i try to avoid passing situations as much as possible in fear the vehicle will create a dangerous situation for myself and other drivers on the garden state parkway. *tr

While trying to accelerate from 50 up to the posted speed limit of 70 on interstate highway 10, the ecoboost engine in my truck stalled and started to misfire and shutter so severely causing my speed to decrease that i had to pull over to the side of the road to prevent from getting run over. *tr

When accelerating the truck bogged. rpm of engine increase truck did not. let off gas and depressed truck began to shake violently. attempting to merge on interstate. had to pull over and shut truck off to return to normal. this has happened several occasions. i have documented each time it has happened with more details each time. ford has looked at truck several times. latest word is that they have a problem, started a tsb however there isn't a fix available. this is very dangerous when driving especially on the interstate when changing lanes or merging from ramp. there is not any warning and scares the devil out of the driver. *tr

There are thousands of reports of this all across the country on the net. it is commonly referred to as a "transmission bump". the problem is, when coming to a stop, the transmission down shifts & causes a bump, or a push. the first time it happened to me, i thought someone rear ended me! it can also happen while you're at a dead stop. the truck actually lurches forward. i was told that this is "normal" for the 6 spd. transmission in my ford. no tsb has been announced from ford to fix this!!! *tr

Traveling down the road. got up to 55 to 60 mph lost power transmission stared jerking. power caught back up and lunged forward. at times the engine stalls and catches back up. at times when you put it in gear it feels like the power train is bumping as though your getting stuck are hit from behind. *tr

While attempting to merge into traffic pulling a trailer i pushed the gas pedal and the truck down shifted but would not accelerate. the truck will drop into 3rd gear and will not exceed 4000 rpm. this has occurred several times and has been in the shop 3 or 4 times. it has also happened without a trailer. on several occasions i have had to pull over and turn the truck off to get it to go. sometimes i can just come off the pedal and press it again to correct. this is a dangerous issue that could cause an accident. the dealer has reprogrammed the truck several times and replaced the converters twice. i have asked ford to buy back the truck but they have not responded yet. the truck is going back into the shop tomorrow and i am considering utilizing the lemon law. *tr
