While driving my transmission changed gears speraticly from 1 to 2 to 5th back to first causing my rear end to lock up temporarily then service light came on. The meters showed that it was the output shaft speed control sensor. I was in waynesboro, ms on john perry mcmichael rd.this problem had occurred in many of the 6r80 transmissions of this same year.
2011 Ford F-150 acceleration complaints
Page 5 of 8: complaints 101 to 130 of 213, newest first, as owners wrote them.
Tl* the contact owns a 2011 ford f-150. The contact stated that the vehicle independently accelerated while stopped and crashed into another vehicle. There were no injuries. A police report was filed. The vehicle was towed to jim navarre ford (2051 w monroe rd, alma, mi 48801), but was not diagnosed or repaired. The manufacturer was not made aware of the failure. The failure mileage was unknown.
Tl* the contact owns a 2011 ford f-150. The contact stated that while at a stop and upon acceleration, the vehicle jerked. In addition, the vehicle failed to properly shift gears. The vehicle was taken to 4 different dealers (dealer 1: bedford ford lincoln, inc., 6985 lincoln hwy, bedford, pa 15522, dealer 2: chapman ford sales, 5201 main st, east petersburg, pa 17520, dealer 3: world ford pensacola, 6397 pensacola blvd, pensacola, fl 32505, dealer 4: autonation ford fort lauderdale, fl 33304), who failed to provide a solution. The vehicle was excluded from the federal safety agency campaign numbers: 16v248000 (power train), 12v190000 (power train) and 11v582000 (power train). The manufacturer was notified of the failure and failed to provide a solution. The failure mileage was not available.
Output speed sensor (oss) failure (recall: 16n02). I was driving down a city street at approximately 45 MPH, when the vehicle suddenly down shifted from fifth gear to first gear and then shifted back into fifth gear after approximately 10-15 seconds. Later that day, I was accelerating from a stop light when the vehicle felt like it had lost power and began to jerk when I pressed the gas. The speedometer stopped working, the info center displayed all dashes, the RPM's increased and the service advanced trac message displayed and the engine light illuminated. I had the codes from the engine light read and it came up as p0720 fault. My vehicle is experiencing all of the signs listed in the recall, but is not included. My truck was manufactured in the dearborn plant within the time frame of the recall dates. I have contacted ford and the dealership and they could not explain why. I have attached a pdf of the recall.
The speedometer begins swinging erratically then the truck automatically downshifts from 6th gear to 1st gear at full highway speed (70 MPH) causing the back tires to lock up and skid down the road. Extremely dangerous. Contacted ford and they said they were aware of the problem and there is actually a recall on this very problem, but not for my truck since it was not within the recall dates by a few months. Took the truck to two different ford dealerships and they said they don't know what is wrong with it, but could do the work outlined in the recall as long as I paid for it. See attached recall notice from ford's website- ford issues safety recall and customer satisfaction program for certain 2011-2012 ford f-150, and 2012 ford expedition, ford mustang and lincoln navigator vehicles in north america to update powertrain control module software and inspect for certain diagnostic trouble codes ford is issuing a safety recall for approximately 202,000 2011-2012 ford f-150, and 2012 ford expedition, ford mustang and lincoln navigator vehicles for a potential issue with the output speed sensor on the vehicle's transmission lead frame. Under certain conditions, the transmission controls could force a temporary downshift into first gear. Depending on the speed of the vehicle at the time of the downshift, the driver could experience an abrupt speed reduction that could cause the rear tires to slide or lock up. This condition could result in loss of vehicle control, increasing the risk of a crash. Ford is aware of three reports of accidents and no injuries related to this condition.
I almost lost my life just leaving work. Made a right onto hwy & almost got smashed, no power in the peddle, with a semi coming at me full speed I'm sitting there trying to go, he blew his horn passing me in left lane... Crazy!!!!!!! This really should be a recall, not just cuz of me but for the safety of everyone!!! Not cool!!! Without a doubt this is a safety defect! Reduced power during hard acceleration the federal safety agency preliminary evaluation #pe13018 status: closed date opened: may 22, 2013 date closed: april 07, 2014 recall: no recall issued component(s): engine engine and engine cooling summary: on may 22, 2013, the office of defects investigation (odi) opened pe13-018 to investigate 95 complaints alleging incidents of reduced engine power during hard accelerations.
I was sitting in a fast food line waiting to place order. The truck was running and my right foot was on the brake. (I am a one foot driver.)the truck began to inch forward. I pressed on the brake and the engine began to accelerate. I pressed hard on the brake and the rear wheels began to spin. I slammed the gear shift into park and cut the engine off. I re-started the engine and was able to pull the truck out of the line. After re-starting the engine a couple more times I was able to drive the truck home. This occurred on october 14, 2016. I parked the truck and called my local ford dealer. He said I needed to bring it in. I needed to move the truck in the mean time and it did it again. The truck accelerated with my foot on the brake. The ford dealership couldn't get the truck to repeat the problem. They talked to the ford regional manager and I was to bring the truck back when they had a service rep available to fully check it out. I chose to leave the truck at the dealership rather than risk driving it. The dealership kept the vehicle for almost two weeks, said they drove it 273 miles and couldn't get the problem to repeat. And if they couldn't get it to repeat the problem they couldn't help. The ford regional manager said the same thing. I have a lot more notes but they pretty much say the same thing. Can you help me? I am concerned about driving the vehicle without it being repaired. Isn't there a class action lawsuit about ford trucks doing the same or a similar thing? Please let me know.
Vehicle loses power and misfires when accelerating especially at 50mph or higher. Recurring problem over the years. Mostly an issue when passing on two-lane highway. Extremely dangerous.
Tl* the contact owns a 2011 ford f-150. The contact stated that while driving at various speeds, the accelerator pedal was depressed but the vehicle lost power. In addition, the check engine warning light illuminated. The failure recurred on numerous occasions. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure. The failure mileage was 86,000.
While driving down the highway about 55 MPH the vehicle will down shift and the odometer will die and drop to zero, most of the indicators will have dashes instead of numbers. The truck will automatically slow down causing me to have to pull off the road to avoid an accident. I then have to turn the vehicle off and remove the key from ignition and restart the vehicle up again to reset all the gauges. This normally happens within the first 10 miles of driving the vehicle. This would only happen on a few occasions now it is happening more frequently. There was a recall issued around the 1st of july 2016 but I was told the software fix would not be ready until the 3 quarter of the year. Ford now wants to charge me $131.00 to diagnose the problem. I should not have to pay for it to be diagnosed if they already have a recall. I wonder how many lives will be in danger until the 3rd quarter update is available.
Tl* the contact owns a 2011 ford f-150. While driving at various speeds with the cruise control activated, the vehicle independently accelerated in excess of 80 MPH. The contact was able to stop the vehicle by shifting into neutral and shutting off the engine. The vehicle was taken to the dealer, but the failure could not be duplicated. The contact stated that the failure recurred on several occasions. The vehicle was not repaired. The manufacturer was notified of the failure. The approximate failure mileage was 110,000.

I have a 2011 ford f-150 pickup truck. Recently I have been experience issues with the truck randomly shifting to first gear. I checked the ford website and there is a recall notice number 16s19 covering this very issue. I took the truck to the local ford dealer and they test drove it. They were unable to duplicate the action. They said that there was nothing they could do. I had no choice but to take the vehicle. The very next morning it happened two times on my way to work. I think this is a very unsafe situation and ford or the dealership should provide me a vehicle until it is fixed. If I experience this random downshift while in traffic it could very easily cause an accident resulting in serious injury. The ford dealer is bedford ford located in bedford pa.
While crossing a major intersection the car came to a stop. The engine and the electricity stayed on however RPM's dropped to less than 1000 and it just rolled to a stop. I pressed the accelerator and nothing happened. This persisted for 10 seconds. Luckily, just before I was almost hit the accelerator started working again and I barely made it clear. I brought the truck in as it is still under warranty and they said they know exactly what the issue is but can't fix it until they can re-create it. They have seen this on many f-150's of this year and type. They have had my truck for 3 days and can't make it happen again so they have asked me to come get it, knowing it has this issue. My take on this is I am a guinea pig until it happens enough, someone dies and a recall starts.
#1: driving down the interstate, attempting to pass a semi; vehicle lost power as I tried to accelerate and we had to coast to a stop. This has actually happened twice. The first time they replaced the intercooler and the second time I replaced the spark plugs. It occurred about three weeks after getting the vehicle it's regular service. If there was a problem with the gaps on the plugs, and they knew cars were losing power because of it, then they should have mentioned that at the service! #2: driving down the interstate and speedometer jumped around and went to zero. After I got off the highway, I lost power and had erratic shifting while trying to cross an intersection. There's a tsb out for this too!! Why isn't there a recall if there's a defective part that creates dangerous situations!?!?
When driving the truck and I hit the brakes, sometimes the car automatically accelerates having a hard time trying to control the speed of the truck. Went to the dealer and it didn't happen to them, can't explain why this happens. Now I have to brake a great distance in advance before actually going to stop because I don't know if and when it will happen again. It also happened when I was backing up into a parking space and had to jam in park to stop it. It just happens with no warning. It has happened several times in the past two years.
Tl* the contact owns a 2011 ford f-150. The contact stated that while driving at 55 MPH, the vehicle failed to accelerate when the accelerator pedal was depressed and the gauges in the instrument panel began to fluctuate. The check engine and the wrench warning light illuminated. In addition, the gear shift indicator began to change rapidly. The failure recurred intermittently. The vehicle was not diagnosed or repaired. The manufacturer was not made aware of the failure. The approximate failure mileage was 75,000.
Tl* the contact owns a 2011 ford f-150. The contact stated that while driving at 60 MPH, the RPM's started revving excessively high and loud without depressing the accelerator pedal. The speedometer, the tachometer and the gear selector also failed. The vehicle was taken to an independent mechanic where it was diagnosed that the body control module and the transmission change sensor needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was 189,000.
Driving on highway at 70mph, I saw my speedometer momentarily drop to 40mph. It did it again about 15 seconds later, and downshifted to about 4th gear momentarily. About a minute later, still at 70mph the speedometer dropped, and the transmission downshifted to 1st gear! My rear wheels locked up, and I lost control, and fishtailed for a few seconds. Luckily I had taken a half day vacation and was not in rush hour traffic. Still other cars had to swerve to keep from being hit. The dearlership was able to reproduce the problem, and replaced a moulded plastic module made by continental that I think contained the transmission speed sensor. So it appears that when the transmission speed sensor signal is lost, the failure mode is to downshift to 1st gear no matter the speed of the vehicle.
Tl* the contact owns a 2011 ford f-150. The contact stated that while driving at 60 MPH, the cruise control engaged independently. The contact was unable to disengage the cruise control while depressing the brake pedal or depressing the off switch. The contact was able to switch the ignition key to the off position to slow the vehicle. The contact was able to restart the vehicle after several attempts. The contact stated that the failure recurred seven times. The vehicle was taken to the dealer for diagnostic testing. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 10,000.
Tl* the contact owns a 2011 ford f-150. The contact stated that the vehicle shuddered and failed to accelerate properly. When the failure occurred the check engine warning indicator illuminated. The failure occurred approximately nine times. The vehicle was taken to the dealer however was not diagnosed or repaired. The manufacturer was made aware of the failure. The failure mileage was 58,296. The VIN was not available.
Tl* the contact owns a 2011 ford f-150. The contact stated that the accelerator pedal and the throttle would remain stuck. As a result, the vehicle accelerated without warning. The vehicle was taken to the dealer where the vehicle was repaired; however, the failure recurred. The repairs were unknown. The failure mileage was approximately 35,000.
Going up highway @ 55mph. Pulled around a vehicle to pass. Once, I was in the oncoming traffic the engine suddenly lost power, chugged, and was stumbling over itself. I then got back behind the vehicle I was passing. The 4 passengers and I were all quiet and then freaked out. After a while we pulled out and accelerated to go up road again, truck dogged out. We had no clue what was happening, but everyone was freaked out. We called birthday party destination to tell them we have vehicle trouble and can't make it. Drove it down hill all the while worried the engine was going to blow. Drove it directly to dealership who stated they had no clue and did not want us to leave it there. Said set up appt. 7-10 days out. Parked it until appt. Then they replaced all spark plugs. We also have had troubles with the braking. Where it suddenly takes extra effort and requires the driver to press hard on the brakes to get it to slow down. When we've driven it to ford for repair they throw their hands up, act frustrated, like they do not have any clue as to what the problems are. We were hesitant to renew our state tags as it sits parked most of the time, since it chugged on level surface with no rain present, and the mechanics light came on. We feel scared driving it and it has remained parked for 3+ weeks. This is our newest vehicle, which looks new and yet we can't drive it. We're not made out of money, and can not easily replace this truck. We want ford to fix the engine and the brakes, and not act like they have no idea about these problems. Ford wants us to take the loss on the vehicle value or continue driving it until something bad happens. They want nothing in writing. And, we do not want to sell the vehicle to a stranger. We'd allow you to inspect our vehicle....and drive it for a test drive. Would you want to be driving this vehicle with your young children as passengers?
I was driving at highway speed and tried to accelerate quickly to pass someone and the truck had major hesitation and shuddering. Continues to do this anytime you try to rapidly accelerate.
Attempting to accelerate to pass a slower vehicle on the highway. Truck began shuddering and immediately decelerated to 50mph. Would not respond for approximately 75 yards, then would not accelerate over 60mph. Two vehicles (one of those vehicles was a tractor-trailer) following had to take evasive action to avoid rear-end collision. Exited the highway, put the vehicle in park. No warning lights were engaged. Weather was sunny and warm. Now vehicle is shifting very hard with a delayed engagement between 55-60mph.
4 months ago I was driving on the highway and my truck went into limp mode, when I pulled over it was shaking violently with a check engine wrench on the instrument cluster. I shut it down and restarted it a few min later and it was back to normal. It was about 1 hour into my trip and around 32 - 35 degrees out, the roads were wet from snow fall. My wife and I own a home in nh so I travel two hours there and home every weekend. I haven't experienced the limp mode again but every time its wet and cold my truck will stall on acceleration, when at a light, and when on the highway the truck will stop accelerating when I try to give it gas. Again, the only common factor when this happens is the temp and moisture in the air, weather its raining, snowing, or the roads are wet. It will happen almost consistently at the 1.5 hour mark of driving. I've been to the dealer about the issue and they keep saying that the computer isn't showing any troubles, but this is getting aggravating. I have the 6.2 v8 so it our issues we are all having has nothing to do with the ecoboost engine. They need to start looking into something that both engines have in common.
Hello, we wish to file a complaint on the 3.5 l eco boost engine in our 2011 f150. We have had numerous issues of shuttering, lurching, "lag", loss of power/lack of response. We first had this issue passing a semi on a 2 lane highway july 2014, no there was no fog/rain. It immediately shuttered, shook,lurched (coughed/sputtered) loosing power as we were passing. We made maneuvers to get to the shoulder where it struggled to stay engaged. We could have been hit head on, rear ended, side-broaded by the semi or worse, a combination of all 3. Not to mention stranded. We have read of other issues, lawsuits and complaints being filed. The "shield" did not work (we have it, installed 8/2014 & flashed comp) it happened again two days in a row last week. The truck had no load either time, what if we were/are pulling our trailer? (the reason we bought this 60k truck, ford said it would) now they claim spark plugs are fowled, that is a new "fix". (not covered) however that is a separate "carbon tracking" plug issue, (the next "issue" could be the ignition plugs fowling due to carbon tracking from the moisture issue) the problem is not plugs, the major problem is moisture! Ford is not addressing the moisture problem causing the "failure". They are fixing symptoms of the issue. The problem-moisture in the pistons water & engines do not mix! They have not fixed the problem which should fall under lemon law. Next there will be a terrible accident (if not fatal) due to the loss of power/response, what then? "..it was operator error, they slowed/stopped in the middle of the lane in traffic"..tests are exactly what they are; tests. We are every day life; drive the truck for transportation, not petal-metal 24/7, "grocery getters", value our truck. Since when are our lives indispensable or not important? When is any one going to do something about this safety issue before someone dies?
I lose power when trying to pass a vehicle and the motor seem to shutdown and shakes.
Lost power during acceleration, engine light came on instrument cluster. Truck had a severe miss. Drove about 20 miles in 5th gear and engine cleared up and light went off. Truck then missed during accelerations all the way home.
Since new, this vehicle has had an issue with a loss of power when accelerating hard. The latest incident, this past october, occurred at approximately 80000 miles. Plugs were bad prematurely and found that it was caused by water build up in a cac for the turbo chargers and there was a tsb. I was passing a car and lost power almost creating an accident. This time, fortunately, a light stayed on so they could diagnose the issue. The dealer did an update per the tsb but ford refused to pay for the update due to the miles even though this issue has occurred numerous times before the warranty had expired. I am disappointed that the federal safety agency did not make the recall mandatory in their previous investigation as I believe water being injected into an engine causing a power loss at a time power is called upon is dangerous.
I was driving on the highway at 60 MPH and my rear end locked up and it almost had a major accident. I searched on line for recalls and on the 2011s they have been having problems with the transmission. I contacted ford and they said that there are no recalls at this time. I found 5 recalls on 2011s f150:1 recall id 68928 electrical system,2 recall id 90589 exterior lighting,3 recall id 84274 structure body,4 recall id 91590 power train automatic transmission,5 recall id 90588 power train automatic transmission control module. The dealership checked my truck and told me that the valve body wiring harness is bad and the repair will cost around $850.00 to repair. The repair shop said that they have been having problems with the 2011 models but no recalls. This is a safety issue and its serious. If I had been driving 75 MPH and my rear locked up on me,it would have not been good and it could have caused a major pile up including injury to myself and others and possible. This problem needs to be looked at and investigated before something happens. I appreciate your time. Thanks
