Engine stumbles or misfires at highway speeds, which lead to a loss of power when accelerating.
Having issues with ford f-150 ecoboost engine losing power during acceleration, on our 2011 model. We have advised ford on this issue, since it's a safety concern, that can lead to a crash or even injury, however ford is not doing anything about it...please help us out !!! The safety of millions of people that has purchased this model truck is in your hands. It's very dangerous to drive the truck on the highway due to the sputtering, that causes you to stahl out... This is a serious issue... Me and my kids almost had an accident due to this factory defect. Please have this truck re-call, or investigate on this matter. Thank you.
During rain storm or high humidity driving conditions, while at a steady speed for a few minutes, I apply the gas pedal to pass or merge, my truck stutters and loss of engine power occurs. When this happened it caused truck to slow down to unsafe speeds rapidly while on highway, causing me to steer to the side of the road to avoid a crash. The truck is still on when this happens but accelerator peddle is useless until vehicle is stopped, after a few moments it will work again. This happened multiple times and on multiple dates. One particular trip from pennsylvania to florida and back, this above condition happened no less than 15 times. Had my truck in for multiple services and nothing, but a code for misfire I believe the tech said. Had all tsb's done as of august 2013. My truck is averaging very bad gas mileage between 8.5 mpg to 12mpg. My truck also stutters while in reverse while backing out of my driveway on cold days.
This is a 2011 ford f150 with ecoboost engine. 3.5 liter v6 dual turbo. I purchased the truck 12-7-13 and it failed on 12-27-13 having problems accelerating. It has no power and the turbos do not work at random. The loss of power all the time is a serious safety concern. Luckily I did not crash or cause a crash because of the issue. But the truck has been in for service since 1-30-14 , has been out of commission for over 30 business days and no dealership can fix it. The truck is under multiple warranties, but the issue of the turbos failing at random / ingesting moisture from the inter cooler is still there. 3/31/14 the truck is still at a dealership.
Tl* the contact owns a 2011 ford f150. The contact stated that while attempting to accelerate, the check engine warning light illuminated as the engine became unresponsive. The vehicle was taken to the dealer where it was diagnosed that a wire connected to a spark plug was faulty. The vehicle was repaired. The manufacturer was not notified. The failure mileage was 72,000.
I should note that my truck has the 3.5l ecoboost engine. This occurred on a very cold morning (-15f) while attempting to pass a truck on a 2 lane highway, going up hill. I had been driving approximately 1 hour when this happened. As I pulled into the left lane and accelerated hard, the truck began to shutter and misfire, losing almost all power. The check engine light flashed 3 or 4 times then came on solid. I was able to drop back into the right lane behind the truck and avoid an oncoming vehicle. I limped the truck to an area where I could get off the road. After turning the truck off and restarting the engine, it ran better but not at what would be considered full power. I got to my destination about 20 minutes later, left the truck sit for about 2 hours and headed back towards home. The engine seemed to run normally at cruising speed. Since that occurance, I have noticed a drop in gas mileage and intermittent misfires or shuttering of the engine when accelerating hard. I believe this has the potential to create a significant safety hazard upon acceleration to pass or to merge into traffic. This truck basically died and lost all power. This is clearly not an isolated issue, as I have read numerous complaints on various ford truck forum websites.
I was driving my ford f150 ecoboost at highway speeds for about 1 hour, a light rain started with humid conditions. While traveling around 60 MPH I attempted to pass another car but my truck would not accelerate. It began to shake and shudder when I tired to increase speed which almost resulted in a collision because I was unable to accelerate while passing. My truck has now returned to normal function but I have become aware that the issue I had has happened to several others. This is very dangerous because your truck is running just fine and all of sudden it will not accelerate.
My family and I were on our way to disney world in orlando, florida when my 2011 ford 3.5 liter ecoboost f150 truck completely shut down on the interstate 10 highway in the middle of nowhere, probably 60 miles to the east of tallahassee florida. At first I thought that we were not going to make it, as the truck completely died out. I pulled off to the side and finally got the vehicle started. We had been steady state cruising with the cruise set at 70 for atleast 2-2.5 hours. After doing some reading I see that it was probably condensation in the intercooler that entered the intake tract when I had accelerated to go around a big truck that was barely making it up a hill on interstate 10. This was a real bad experience, this has happened atleast 2 times since then. Luckily I have not had a wreck or crashed, but as I keep reading up, I see many people complaining about the ecoboost f150. Now, I have a truck in the shop with a blown motor, and I can only imagine that the water getting into the motor and the motor trying to compress that water was what caused my engine failure. I metal from the internal rotating assembly shoot through the side of my engine block last week. I believe that happened due to the water and the water bending the connecting rods. Please help.
Since owning a new 2001 ford f-150 ecoboost, I have noticed several issues with the engine. Loss of power when accelerating, shuttering when braking and poor fuel economy. I have taken the vehicle in for service and they have applied technical service bullitins, but the issue returns. The latest problem was a failed coil pack causing my vehicle to almost stall on the highway. Ford didn't cover the part under their powertrain warranty.
We were driving in normal conditions, going about 40 MPH, all of a sudden we lost power/acceleration and truck jerked, and brakes seemed to applied by their selves very hard. This seemed to happen sporadically until about a week ago. Its happening now at least 3 times a week. The truck is driven everyday on the interstate and my husband is very concerned that he is going to cause an accident. It happened yesterday and he said it was so bad, when the loss of power happened, the brakes locked so bad the tires just screeched. He took truck to the dealership on 3/4/14 and they could not find anything wrong with the truck. On the way home from the dealership (same day) it happened again. After the dealership told him that, I began searching on the internet and found the loss of power/brake problem. (moisture in cooler causing loss of power problem in f-150 echboost engines) he called the dealership back and he told them about the info on the internet that we had found, and that if had happened again that same day, they told him they were aware of the echboost problem, but can't do anything about it until a recall happens, so they did nothing to the truck .this is definitely a problem and it is going to cause a collision and possible death or injury when this happens. There definitely needs to be a recall on the f-150 ecoboost trucks. Please help everyone that owns this vehicle and issue a recall.
While accelerating the truck hesitates, looses power and jerks violently, the check engine light flashes several times while passing a vehicle. When the truck jerks and looses power it feels like the engine is about to explode. Has almost caused several accidents because of the sudden lost of power. It appears to me that the truck is misfiring.
Accelerating onto the highway, experienced loss of power while check engine light was flashing. Cars were swerving around me due to my speed being slower than the flow of traffic. I put hazards on and pulled over. This is not safe for me or drivers around me. Dealer said it was an engine misfire and replaced the spark plug and coil. Since this incident it has happened multiple times. The dealer replaced another spark plug and coil. I took it in the last time and they flashed my computer and sent me on my way. The problem is still not fixed on my truck.
Towing a 9500# fifth wheel trailer on interstate complete loss of power shuddering and inability to accelerate.
Ecoboost f150. Loss of power when raining while towing. The truck started shaking, lost power and the cel flashed. We were nearly killed on the interstate. This happens every time it rains and we drive more that 45 minutes in the rain. My family no longer feels safe. Cars have ran off the road to avoid hitting us. I am afraid my family will be injured. Ford keeps sending me away saying they cannot duplicate the issue, (no kidding, it has to be damp and driven in for an extended period).
When passing on interstate truck lost power an went into a limp mode check engine light went to flashing which made the truck unsafe when other traffic was moving at a higher rate of speed.
Driving at highway speed (apx. 70 MPH) attempt to pass a slower vehicle, and upon acceleration, the truck lost all power, and would not speed up. The check engine light came on, and stayed on until the truck had been turned off and restarted. I have experienced this problem on numerous occasions, and it always seems to occur in the rain, or high humidity days. I have narrowly avoided an accident on 3 occasion. The dealership where I purchased the vehicle has told me to use "fuel additive" every time I complain, stating the problem is water in the ethanol that is blended with gasoline in texas. I recently learned about this problem having a fix, through the web, and I am now told "there is a fix, but it not a warratny situation"
While driving my f150, v6 ecoboost engine, down the interstate, when I try to accelerate,the truck to pass vehicles and or move out of the way of on coming traffic, the engine gives me nothing and shutters, feels like it is missing. I originally started to feel this in 2013, took it to the dealership, cause I thought it could be a transmission issue, and the service rep only asked if a light came on and if none has come on, probably won't show anything. I am outside of my warranty now and the truck is shuttering very badly when I try to accelerate anywhere, besides my gas mileage has dropped significantly, which now can become a epa issue. I have read about a lot of issues concerning this year ford with same engine with no outcomes. I have been told, once again that if I don't have a check engine light, then it probably wont show a code. I don't know where else to turn but to at least have a complaint filed where there is an issue with the 2011 ford f150 v-6 ecoboost engine.
Has a problem with the turbo intercooler getting condensation and make the truck lose power check engine light starts to flash whole truck just shakes had it to the ford dealer had to put a new cat converter on my warranty didn't cover any of it I said this is fords screwup why don't they have a recall ended costing my $800.00 not to impressed ford motors also intercooler was full of ice and water.
The vehicle lost power after accelerating to higher speed when entering the highway. This has happened multiple times when passing or entering highway at higher speeds.
I was traveling in florida on the highway and went to pass a semi. The engine sputtered and I lost power. The check engine light came on and I had to pull off of the interstate. I shut off the engine and restarted it. The check engine light went off and the engine ran fine. Several times since, the vehicle would sputter on hard acceleration and the engine light would blink. The latest time this happened, the engine light stayed on. When I took it to the dealer for repairs, I was told it was a faulty spark plug and coil and was not covered under the drivetrain warranty. The truck has done this several times since this repair.
I was traveling on the interstate where I live and was trying to get up to speed to merge with traffic and when I accelerated my truck lost power and began to sputter and shake, and would not get up to speed, and the check engine light came on, when I took to the local dealer where I purchased it I was told number 2cylinder and number 4 cylinder was mis firing, that I needed new coil packs so I had them replaced and I am still having the same problem.
I was on the enter state two lane thank god. It was raining and I started to accelerate to get around a big truck and my truck started to shudder and lost power all power. My truck has the 3.5 liter ecoboost engine. This is the third time this has happened to me.
Truck started to shake violently when accelerating. Felt as if the wheels were loose or the u joint for the drive shaft was going bad. Had to let off the gas. Has been ongoing from the time I purchased the vehicle to present time.
While trying to merge onto the highway while under medium to heavy throttle my 2011 f-150 ecoboost lost all power while shuddering to the point it I had to abruptly get out of traffic and pull off the side of the road. As this was happening the check engine light started to flash and continued for a few minutes. After sitting for a few minutes the truck behaved almost normal as long as engine RPM was kept under 2500 above that it continued to miss and have a loss of power. By the time I got it home the cel was(is) on continuously. This all happened during rush hour on a very busy socal highway and could have been catastrophic.
I have already reported this piece of junk but needed to add to the list?. We, as of last week, are on our 15th rental while the dealer and ford are trying to figure out whats wrong with it again?. The engine light has been coming on since the week we bought this junk and is still flashing while we drive?.. The dealer has asked ford to put in a new engine several times but ford for some reason wants the dealer to just keep replacing the same parts over and over again?? We have had several new sets of plugs.. The others crack and short out? We've had cam phasers and sensors replaced?? Fast forwarding through many parts repeatedly replaced, the dealer now says there are parts sheared off in the engine and are asking ford, once again to replace the engine?. We are waiting on ford to (probably) decline the dealers recommendation?.. Ford stopped calling us back, we have left several messages and they just keep passing the buck onto the poor dealer, who has been trying to help us?.. Ford should have taken this lemon back long ago and gave us a new one?.. Our 15th rental might be with us for some time while we wait on an answer?? We sometimes have our rentals for over a month at a time??. Its nice to keep paying on time for a vehicle that we don't even have?(sarcasm).
While driving at 55mph attempted to pass a vehicle on a two lane highway. Accelerated hard to pass and heard a loud metal on metal sound and lost power briefly. I was unable to replicate the initial incident, but now the truck randomly misfires and shutters under hard acceleration. Sometimes the check engine light will illuminate other times it does not. Dealer has been able to replicate the misfire but claims they can do nothing more. This is a safety issue because when power is needed most it is unreliable. I have escalated the matter to the corporate level at ford but have not heard anything back yet.
2011 f150 ecoboost at 57k miles mid july 2013 experienced violent shuddering lose of power pulling up hill at 60 MPH. Engine light came on. Taken to dealership where repair was listed as #2 coil pack costed $277. Now jan 2014 six months and 13k miles later same event. Check engine light came on twice while driving to work. Used on board diagnosic tool I had purchased and truck coded p0303 as #3 cylinder misfire obviously the #3 coil pack has gone bad at 70k miles.
When I tried to accelerate the truck started to buck violently and lacked power. After releasing the gas pedal and coasting a bit I was able to slowly regain speed. It was raining at the time and had been raining most of the day on 12/29/14. We have not had a recurrence but have not had any rainy days either.
Under acceleration between 60-70 MPH, trucks starts shuttering and decelerating. The check engine light starts blinking and will blink for about a minute before staying on. I was nearly rear ended by a semi entering the highway today as I was trying to accelerate up to highway speed and at approximately 65 MPH, the truck started decelerating and shuttering down to 35 MPH before I could get enough power to maintain that speed and get off to the side of the highway.
