Was traveling up the roadway on 6/1/14 in our 2010 F-150 XLT and went to make a turn into an intersection. The vehicle stalled and was rendered useless in the middle of the intersection. The vehicle lost complete power, steering capability, and braking was diminished tremendously. We were stalled in an intersection with cross traffic approaching at 55mph. With little time due to oncoming vehicles, was able to immediately restart the engine and proceed, before oncoming vehicles approached us in the intersection. Not very safe being that my entire family was in the truck. Ford has issued a service bulletin about the issue with the vapor canister purge valve and its needing to be replaced. However, I believe this is a serious safety issue being that the vehicle stalls when reducing speed (such as turning into intersections with other oncoming traffic coming at you). There is no recall in lieu of this potentially dangerous situation they are causing. Additionally, this problem with the canister causes a tremendous vacuum on the fuel tank, so much that it damages internal components and has raised questions about whether it is affecting the stability of the actual tank itself. When you go to fuel the vehicle, there is so much of a vacuum that you hear it release the pressure when inserting the nozzle. Immediately after fueling, the vehicle will not start for several minutes. This issue needs to be corrected before someone is seriously injured or killed due to their vehicle sitting in the middle of a roadway and being hit by oncoming traffic.
The contact owns a 2012 Ford F-150. The contact stated that during heavy rain and attempting to accelerate, the vehicle hesitated and stalled. The contact mentioned that the check engine light illuminate. The failure recurred three times. The vehicle was taken to the dealer. The technician was unable to diagnose the failure. However, he advised the contact to bring the vehicle back when it rained in order to duplicate the problem. The vehicle had not been repaired. The manufacturer was made aware of the problem. The approximate failure mileage was 6,000.
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.
I experienced the exact problem you've already closed a case for. See link below. I narrowly escaped a bad accident. I think you need to reopen the case and force Ford to design a real fix (not a shield that disables the charge air cooler). You also need to force a recall before the accidents happen and lawsuits start. www.autoblog.com/2013/05/28/Ford-F-150-ecoboost-in-NHTSA-probe-for-acceleration-issue/.

My two children and I were driving up hwy 75 North from macon when we accelerated to the next lane. The speed limit is 70 so we were just going to pass in at a normal rate when the engine just quits and the whole car starts to shudder. Now I have had this happen at 19,000 miles and took it in to the dealership. This was only about two months ago. Went in today before I read all the complaints about this 3.5 eco boost engine and the similar problems I experienced. It was raining on when we had this happen but it occurred before with no rain. As the truck stopped and shuddered we were finally able to get to side of the road and did not get hit by oncoming traffic. There are six lanes of traffic in this area. Surprised today when I went to the dealership and told them what was happening and they didn't even know of the problems or have ever heard of it. "???" so based on what I have read I called back only to find out they have had issues.
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!!!!!!!.
My 2012 truck has the 3.5L eco-boost engine and it has shut itself down (gone into limp mode) at least 12 times. This morning (4-17-14) it just happened three times within a 45 min window. The temp outside was 50 degrees F and not raining. Normally this vehicle goes into limp mode during a turn or after a stop, but it has also happened at normal driving speeds (45-50mph). This is a new vehicle and I am no longer comfortable driving this vehicle due to safety concerns. This issue has almost create three separate accidents.
Engine shudder/vibration after accelerating. Loss of lights, dash instruments, radio out. Vehicle check engine light came on. This has happened three times before. Taken to dealer twice for repair.
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 own a 2012 F150 platinum truck with an ecoboost engine. We purchased the truck new. I was on the interstate and was trying to pass a slow moving car. The vehicle went into overdrive and began to shake. I pulled over to the side of the road. The check engine light was on. I turned off the vehicle and waited a moment. When I restarted the truck I drove to the nearest dealership. It did this again twice on the way to the dealership. They said that the wiring was at fault and replaced the defective part. Then at 34,470 it occurred again. We were on a highway about to pass someone when the truck began to shake and the engine slowed and would not accelerate. The dealership suggested that we use a higher octane fuel and said they could not find anything wrong with it. This problem occurred eight additional times. Then at 82,200 miles we were traveling up hill and heard a loud boom. We had it towed to the nearest dealership and found out that a connecting rod had broken causing two holes in the engine. We had to have the entire engine assembly replaced along with two new turbos. Ford would not cover because the engine had 82,200 miles and the power train warranty ended at 60,000 miles.
While attempting to merge onto the highway the engine shuddered and the cel came on which put my truck into limp mode. Since, under any load the vehicle shudders and goes into limp mode when there is any load put on the engine.
When accelerating to merge onto 4 lane byway veh. Lost all power started eng miss. Throttle had no effect, coasted along in emergency lane for about 10 seconds. Veh started to accelerate while still missing for about 5 more seconds. 3/4 fuel tank. Ps was a auto tech. For 28 years with U.S.P.S.
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.
Ford F150, 3.5L ecoboost engine- while driving in rain, vehicle hesitated and misfired, with an associated check engine light on some occasions and not on others. Seemed to happen after cruising and attempting to pass another vehicle. Was unable to accelerate and continued to slow to 50mph. Had to ease on the throttle to slowly accelerated after the condition cleared. Vehicle in the shop 4 times for updates, 3 for changes to the intercooler and the last was for a change of the catalytic converter.
The contact owns a 2012 Ford F-150. The contact stated that while driving 65 mph and attempting to switch lanes, the vehicle began to lose power and engaged into limp mode. The contact pulled the vehicle over, shut off the engine and once restarted, it functioned properly. The vehicle was taken to the dealer for inspection where they stated that the computer needed to be reprogrammed. The vehicle was repaired but the failure recurred. The manufacturer was not notified of the failure. The failure mileage was 7,000.
Since new my fuel mileage has been declining and I was experiencing a shudder, with no check engine light (cel). Dealer performed a tsb and replaced the charged air cooler and reprogrammed the PCM. This left me with worse mileage and a noticeable loss of power. This progressed until 1-19-14 where I lost engine power and the engine began to shudder when trying to accelerate to pass a slower moving car. When I floored it, the trans shifted down to 2nd, and the engine shook and the truck slowed. Once I left my foot off the gas, and coasted for 30 seconds, it returned to normal, unless I floored it again. No cel was observed until the next day on the way to the dealer. They replaced all 6 spark plugs due to fouling. I think there is water ingestion issue and that is what caused the plugs to foul. My concern is that if I had been in front a fast moving vehicle, I may not have been able to accelerate and gotten rear ended.
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.
