I purchased a new 2012 Ford F150 platinum 4X4 ecoboost truck in June 2012. Around 2014, I experienced a complete loss of power and major shaking or shuddering when I went to pass a vehicle in the highway. I thought it was a misfire issue and called the Ford dealer I purchased it from. They asked at the time if it was consistent and I said it was not. They advised that I should just keep an eye on this and that I had an extended warranty. I was told to bring it in if it continued. I have also done a good number of all maintenance related check ups and services with the Ford dealership I bought the vehicle from. It happened a few more times over a 1 year period. I changed the spark plugs as I thought it was a misfire but it continues to happen. The last episode nearly resulted in a collision. I took my vehicle to a Ford dealership near my home and they tested it. Computer reading says it is a P04300 - bad inner cooler. Fix is $1700 per dealer (new inner cooler, new catalytic converter, new boots, new plugs and adding a shield) but that since I am now at 88K, emission warranty ended at 80K and I have no financial support from Ford. I advised I was never told about an emissions warranty and that this is not my driving or mileage issue and that Ford acknowledges this is a design flaw in the charge air cooler and had a redesign. This is a major safety issue and if Ford recognizes this as their design flaw and is now happening to my Ford vehicle, I need them to help accept this as a warrantable item and accept the repair from the dealership. Please assist. Kindest regards.

The contact owns a 2012 Ford F-150. While attempting to accelerate from a stop, the vehicle failed to accelerate and then accelerated unexpectedly. The failure occurred on over ten occasions. The vehicle was taken to a dealer where the failure was unable to be duplicated. The manufacturer was not notified of the failure. The approximate failure mileage was 35,000. The VIN was not available.

When there was snow and ice on the highways I put my truck in 4 wheel drive and when turned back into 2 wheel drive I began to notice a grinding and vibration noise that occurred when turning. Then couple weeks later the noise started when backing out causing truck to shake and lose power to barely back out. This noise continued and has gotten worse. Was taken to dealership and looked over. Updates were made as well as oil change but days later noise came back. Since 2/12/15 my truck has been in the service department four times and has performed recommendations by Ford but days later noise comes back. The last time my truck was in I was told by the owner and service manager my truck is not fixable as they were informed other 2012 F150's are having same issues and an investigation is being done. Since this my truck is shaking more backing up, jerking the vehicle on the highway as if losing power than will gain power and jolt forward, I hear this grinding noise all the time when driving at different speeds from 30-60 mph, turns, and backing up. The other issue is when truck gets to 60 mph or higher it does not shift down unless I let up on pedal and then push it again. I am feeling unsafe in this vehicle as twice now I have heard a popping noise while driving with this noise. The dealership has told me there is nothing more they can do. The issue has been reported to Ford and they have done nothing for me. I want to get rid of this truck as I do not feel safe driving it like this.

Multiple occasions go to step on the gas and the truck just doesn't accelerate, feels like a misfire or almost about to stall, this usually happens when at a complete stop at a light and light turns green, has also happened when rolling in traffic or trying to get onto highway at the on ramp. Another time driving on highway, stepped on gas and truck lurched forward as if someone hit me from behind and RPM kept accelerating even though I was not stepping on the gas. Have brought this to dealer and they claim they can't find anything wrong. I believe these are particularly dangerous because I'm expecting the truck to move so I can go along with flow of traffic and it just hangs on me putting me in a bad situation or it launches forward making me momentarily jerk the wheel and lose control. Possible known issue? (www.usatoday.com/story/money/cars/2013/05/28/Ford-F150-ecoboost-government-probe/2367197/) thanks

I was with my family on the way to church. I was making a right turn out of our neighborhood onto the highway when all of the sudden there was a complete loss in power and was unable to resume acceleration. The highway also has a moderate incline in slope which caused the vehicle to slow dramatically. We were almost rear-ended from the car heading in the same direction which was originally a substantial distance away. Luckily the car that was approaching from behind was able to slow down fast enough considering we had a 1 year and 4 year old son in the back seat. I called the local dealership and the earliest appointment they could offer to check the problem was on Wednesday 10/10/2014. This is over 3 days after the incident occurred. The truck only has 40,000 miles on it so I began researching this issue. I discovered that there are more than a substantial amount of complaints and it seems Ford is aware of the issue and is even attempting to modify the air induction system and re flash the PCM. With issues like the millions of vehicles being recalled for airbags that have led to serious injury or death, far beyond the manufacture originally becoming aware of the issues. How long is the issue regarding the 2011-2013 Ford F150 ecoboost going to remain shoved under the rug? how many lives have to be lost before Ford takes accountability for putting the public at risk. In their report to this specific issue (on the NHTSA website), it is more than obvious they have identified a defect in the 2012 Ford F150 and the ecoboost engines within the trucks. Can you help me understand how and why they are not being held accountable for risking the lives of many people. Also, why is the NHTSA allowing Ford to shrug this off and close this investigation" there is a clear defect present that has the potential of leading to loss of life. Is this not pure negligence"

When you press the throttle pedal to pass the vehicle has a slight acceleration and then shakes, shudders and will not accelerate. I need to coast for several hundred yards before the system recovers and the truck accelerates. This happens all summer long pretty much every time I need to pass. My Ford dealer says they have applied the service bulletins but that does not correct the problem. In your investigation of this matter it is stated that Ford says you can still accelerate I can tell you that is absolutely not true with my truck. I should note that most of the time I am pulling an 18' fishing boat that weights about 3000 lbs. On at least six different occasions now while on vacation I have been in a long string of traffic behind either motor homes or logging trucks that could not go highway speed, I pull out to pass them step on the gas, it shakes, shudders and there I sit in the oncoming traffic lane, meanwhile the string of vehicles behind me have closed the gap, I cannot pull back into the right lane and I cannot accelerate to get in front of them. I end up just slowly moving back to the right hoping the other vehicles will back off and move out of the way, then comes the blasting of their horns and shaking of their fists when they eventually pass me. I cannot imagine how this is not considered a safety issue. Ford specifically markets this ecoboost engine based on it's torque for towing to people that need a truck for towing but you cannot use any of that torque all summer long and I am pulling a boat that is only at one third of the towing capacity.

While getting on the highway and accelerating, my truck began to shake and lose power. I took it in to the shop afterwards and they had to replace all spark plugs and 1 ignition coil. After researching this, I found out this has been an issue on several 2011 - 2013 model eco boost. Please force a recall, as I do not feel I need to pay for something Ford is responsible for.

For the fourth time, my 2012 Ford F150 ecoboosted engine stalled or shuttered when hauling a load (trailer or heavy bed load) in a high humidity environment. I was pulling a U-haul trailer behind my truck and it was raining heavily. When I punched the accelerator to pass a slower vehicle, the engine stalled, sputtered, and nearly shut down. The "check engine" light came on for about a minute, then turned off once the engine had cleared what felt like condensation, and returned to normal operating mode. When I took the vehicle to the dealership to complain (for the 4th time), they told me that they were of aware of a design problem with the intercooler on 2011-2013 turbocharged vehicles, but since they could not verify the defect "code, " Ford would not reimburse them for the service fix. This is clearly a safety and environmental issue as the service bulletin that Ford issued to correct the problem, requires replacement of the catalytic converter as well. Frustrated!

While traveling on the interstate, my vehicle starting shuttering as I changed lanes to pass another vehicle. As I accelerated, the engine lost power, and the engine light started flashing. My vehicle continues to shutter under hard acceleration.

- Greeneville , TN, USA

While traveling at 55mph, up a slight incline on the highway, I pulled out to pass another vehicle. As I pressed on the accelerator I had no engine power and the F150, lariat, eco boost began to slow. The check engine light came on and flashed. I let off of the accelerator and then pressed it down again. This time I had power. I pulled back into the lane and everything appeared to be in working order.

Pulled into parking lot and truck stalled. Could not steer. Could not accelerate. Warning light popped up said low oil pressure. Was not on a hill. Ran vehicle health report through Ford sync service and everything came back ok. Will call dealership next. Had my daughter with me and it scared me to death.

2012 Ford F-150. Consumer writes in regards to acceleration problems. The consumer stated as he tried to merge into traffic on the interstate, he floored the accelerator pedal, but the engine shut down completely. He was able to get the truck off the main interstate and into the emergency lane. The engine light came on. He let the truck sit in the off position for approximately 10 minutes and then he re-started the truck. At that point, he was slowly able to accelerate while in the emergency lane, to a speed that allowed him to re-enter the interstate. All attempts to accelerate quickly failed and it would only accelerate gradually at slower then normal speeds. He continued his trip with the engine light on and at his first opportunity he took the vehicle to the dealer. The dealer returned the vehicle to the consumer saying they had fixed the problem. The truck performed well for the next year without any incidents, there were no occasions where quick acceleration was required. In October 2013, he made another trip, and the same incident happened. Then engine shut down again in December 2013. The dealer stated they made a different repair and they returned the truck to the consumer. The engine shut down again in April 2014. The dealer kept the vehicle, for two weeks, stating they were unable to find a problem.

Driving to work on June 9 at 8:00am after a hard rainstorm, on South memorial parkway just North of green cove road, traveling about 40 to 45, slowly accelerating, the rear end of the F150 locked up, tires squealing, began to fishtail to the right for a few seconds, then released. I thought I had been hit from the rear, no cars behind me. Temperature gauges were fine, the gear display on the dash board showed only gears 1, 2, and 3. gears 4, 5, and 6 were not displayed. I sped up and the transmission would not change, I slowed down and the transmission would not change, I eased the transmission into neutral and pull to the side of the road and put the transmission in park. The gears 4, 5, 6 were redisplayed. There were no fluids coming from the transmission under the truck. I eased back into drive and noticed a little bit of a shudder around 3rd gear. I took the vehicle to the Ford dealership and they have told me that there was no computer code and it was likely to be a computer glitch and there was nothing they could do. I asked if it would be recorded as a complaint and was told no, that unless they could witness the event or there was a computer code, the complaint would not be documented....I escalated to the service manager, we agreed to drive the truck for a bit and see if they could reproduce the problem, but, that there was nothing else T hat could be done. Obviously, if I had been doing 70 mph, the vehicle would have been much more difficult to control. If you have any questions, please ask.

I was merging onto an interstate, accelerating from 20 mph to 65 mph to blend in with heavy traffic. The engine began to spit, sputter and shake and bogged down and wouldn't exceed 50mph. With a tractor trailer coming I had no other choice but to abort my merge and pull to the side of the road. I then waited for all traffic to subside before I made another attempt to pull onto the highway. I took the truck back to Ford. They could not duplicate the problem. I have had the truck in for many issues(slow speed shudder, high speed shudder, emergency brake issues, warped rotors, electronic problems, tire issues, acceleration hesitations, rough idle, failed brake pump, and more with less than 30, 000 miles) all of which Ford states are characteristics of the vehicle! this is my family vehicle that I Transport my 3 children and their friends. What will it take for Ford to resolve the problems they have with these trucks?! do people have to be killed before anything is done........ like with Chevy!!!!! Ford is covering up the issues they have with the #1 selling truck in America. It is a shame that people have a facebook page on the problems they have with their F150 because Ford covers up the problems because they don't know what to do to solve them. They told us it is a characteristic of the truck..........really!!!!!!!.

Traveling on interstate highway from St louis to memphis in right hand lane. Accelerated to pass slower traffic when truck begin to shake violently, lurching forward and back. All the while losing speed and made me fearful to attempt to try to pass or merge. This continued all the way back to memphis. I took the vehicle in for service and described the problem to the service tech. When I picked the truck up the service ticket said "could not duplicate the problem. Since then the problem has gotten worse. I never know when it will occur. It could be rain or shine and there doesn't seem to be a pattern. It is now a weekly/daily occurrence. It has contributed to several near miss accidents. I am afraid to drive anywhere except side streets and I avoid the interstate hwy. The problem is so bad and the vehicle shakes so violently I was looking in the mirror to see what I had ran over. It is a serious safety issue that my Ford dealer denies exists!

I was driving my F150 2012 ecoboost on an onramp getting on to the freeway. It was raining, wet and about 50 degrees. I accelerated from about 35 to 65 mph to change lanes and get in line with traffic. The engine lost power and the truck started shaking. There was about a mile stretch where the vehicles power was completely unpredictable. When I let my foot off the gas the truck would stop shaking. This was very scary as cars were bearing down on me from behind and I had to get over to the far right lane incase I needed to come to a stop. The vehicle then seemed to function normally and I drove about 5 miles straight to the Ford dealership.

1st time happened when trying to pass a big truck, pick up lost engine power during acceleration that I barely made it, opposite traffic coming, vehicle lost all chances to made on time I was afraid not to pass on time this is a hazard issue if it happens again, I had to stop and shut down vehicle because I had a engine check massage at the main screen of dashboard with the wrench character image, after I restart vehicle everything was normal. 2nd time happen when made trip to Texas on December 2013, when trying to enter freeway I had to speed up and suddenly pick up again lost power and start shaking I could no gain any more speed over 50-55 mph I almost got rear end it by a car on the back that was already in the high speed stream. This time the check engine came on, ;later started to drive ok. When I came back to home town I took vehicle to check the check engine light at autozone and retrieve the P0430 code. I took vehicle to dealer because still under warranty and explain everything. They check vehicle and retrieve the same code, they replaced only the driver side catalytic converter. I was researching on forums and they commonly have to replace not only cat but have to change intercooler, change plugs and re-flash ECU and or place a deflection plate on current intercooler but home town dealer only replace cat, I don't think this will fix issue. Please push Ford to address this issue, for experience this needs to be classified as a recall because safety issue is involved when you lost power when is need it. The actual intercooler on pre 2013 is not good because tends to accumulate condensation and this is sucked under boost condition and probably causing multiple misfires that leads to unexpected power lost and vehicle shaking. My wife and I bought this F150 new on 2012 ecoobost engine re great but this issue needs to be addressed.
