general problems of the 2011 Ford F-150 - part 1

Approximately one month ago, I noticed that the vehicle would not accelerate the way it normally does. A error code came on. I took the vehicle to auto zone for error code check. I was informed that the powertrain control module speed sensor had gone bad. I looked this up and found that Ford had a recall on 2011 Ford F-150s for similar issues. I disconnected the battery, as recommended on an internet site, and the vehicle began to operate normally. About one week later, I noticed that the vehicle would not shift above third gear and was accelerating very sluggishly. On further investigation I fount that the vehicle would not shift out of third gear (up or down). I again disconnected/reconnected the battery, and again it began operating normally. I contacted the local Ford dealership and they said that I should have received a letter in may 2019 about the pcm recall. I didn't recall receiving the letter, but Ford motor CO. Customer service says the pcm was actually reprogrammed on March 29, 2019 to repair the issues related to the recall. My concern is that the pcm speed sensor is malfunctioning again even after the repairs were supposedly performed by Ford. I am concerned that the vehicle may again be potentially unsafe to operate at highway speeds. I wanted to make NHTSA aware of the potential for ongoing safety issues with this vehicle even after Ford's proposed fix.

I was driving in the morning car was started to lag on accelerating and shifting gears slightly. My dashboard and gps system flickered on and off when this happened. The truck putted as well. On my way home the car had trouble accelerating and dropped from 5th gear all the way to first causing me to almost lose control of the vehicle. It continued hard shifting and loss all acceleration. It continued flickering everytime it would sputter and slip gears, gps and dashboard would flicker. They gears were going haywire. I could not accelerate with the pedal all the way to the floor, and was hard to turn steering wheel. Almost like the truck was coasting. When we took it to the mechanic they stated it was a transmission range switch which is an issue and many f150's of my year, make and model. My vehicle was not listed as a recalled vehicle yet has the same issue as the other recalled ones. Total repairs are going to cost around $2000. I have not driven my vehicle since the incident and I am frightened after almost losing control from the hard shifting. Prior to this the vehicle ran great. It was an out of nowhere issue. The truck has been maintained well, with all oil changes, and regular maintenece. There is less the 96,000 mile son the truck as well.

Hard downshifts from 5 to 4. At low speeds, like parking lots it shifts hard from 1 to 2. At freeway speeds while attempting to pass instead of dropping a gear to passs it downshifts to 1st, rpm’s shoot up and it results in having to pull off stop and place in park. Once in park back to d and able to take off. At any speed from 30 mph or more there is a sort of “tap of brakes” feeling every . 15 of a mile.

When driving on the interstate with the normal flow of traffic at 55mph, the vehicle abruptly downshifted from 6th gear to 1st gear causing the the vehicle to lock up an nearly caused an accident. This was followed by a a mechanic warning light and the speedometer to lock out and no longer work. Once pulled over, the vehicle was powered down. When the vehicle was turned back on operation returned in a limp state.

2011 F-150 super crew laredo is sifting gears down by its self at high spends causing immediate car speedometer cluster going to zero and not be able to accelerate. There was a customer satisfaction program 19n01 it was 10 yr 150,0000 miles.

At highway speeds speedometer started occasionally dropping to zero while actually going 55-65 mph. Then it became quite frequent and the truck started spontaneous downshifting causing the rear wheels to break loose and the rear of truck to fishtail. It was terrifying.

While operating vehicle at highway speeds the speedometer suddenly drops to zero and the transmission downshifts to first gear without warning. Apparently a failure of the transmission speed sensor. (?) a driver unaware of this issue that continues to drive results in excessive heat and pressure developing in the differential. . A recall has been issued by NHTSA but Ford and the local dealer refused to address the problem because my VIN was not included in the recall.

While driving at about 50 mph truck suddenly down shifted to 1st gear locked up rear wheels and sent engine into a roar. Instrument panel not showing speed or any information. Had transmission shop trouble shoot and determined frame rail failure. Replaced frame rail and serviced.

At 45 mph the gear downshifted causing back tires to skid. Then gear illumination disappeared and wouldn't go into gear(while trying to leave a steep boat ramp) very scary!.

Unexpectedly downshifting into first gear result in a loss of vehicle control happened on September 20, 2024 and continue on and off.

While driving, my truck down shifted suddenly. Already 3 times on different occasions.

A recall was issued for an intermittent failure of the transmission speed sensor (oss), campaign 16s19. I took the truck to a Ford dealership, mike reichenbach Ford, in florence SC. The technician reprogrammed the pcm. This did not resolve the issue and the truck continues to downshift or not shift at all. I spoke with the dealership and with the Ford motor company. I believe this truck was taken to a dealership more than once without the issue being resolved. I am respectfully request Ford make good on the safety recall of a known issue.

Was in 6th gear(on a 6speed transmission) and immediately my truck downshifted to 1st gear causing my back tires to lock up and almost crash into a median. This is due to a csp that Ford no longer offers to fix because it "expired".

Transmission downshifted to 1st gear causing the rear wheel to lock momentarily while driving 40mph on the highway and then shifted back to 5th gear. Transmission will occasionally stay on 3rd or 5th gear when at a complete stop. Dealership refuses to remedy recall issue for my truck. I have complained multiple times.

My truck start to accelerate by itself and the light indicator goes crazy from parking to gear 1 from there the truck it can be controlled.

My truck is doing exactly what the recall on all the others. Check engine light on for input shaft speed sensor. Speed odometer quit working then engine light came on for speed sensor. Now when you drive on highway it will be fine then all of a sudden throw a wrench light and truck goes into limp mode and barely moves. You stop turn it off it resets but still isn’t right it doesn’t seem to shift at proper times seems to be shifting to often.

Ford 150 2011 has had acceleration issues for the last 2 years. I heard there was a recall on this model of truck with the eco boost but mine was not on the list but I am now having issues and mechanics are having a difficult time figuring out what has been happening. Code light doesn't specify a problem.

I was driving on the highway at 65 mph and the truck downshifted on it's own from 6th gear to 3rd gear causing the truck to loose power. This has happened twice while driving on the highway and the transmission recall has been updated prior to this.

Truck took off with out me touching the gas in a parking lot had to hit the brakes several times then shifted hard and speedometer quit work and the wrench symbol popped up on the dash and it throw code po720 which is the output shaft speed sensor /lead frame.

The vacuum pump recall was replaced in 2016 and it’s bad again. I have the emissions warranty with Ford I am 6 owner the other 5 owners were resale so I get the one time lifetime emission warranty. The truck is doing all kinds of crazy stuff.

This vehicle has an automatic transmission. It will not shift out of first gear in the drive setting and the speedometer registers 0 mph when moving in first gear. If I shift to the manual setting, I can shift up. I did not notice if the speedometer registered my speed at that point.

Just out of no where the vehicle stoped and wouldn’t go into gear.

Truck transmission shifted into 1st dear from 4th while driving on a large 4-lane road in the middle of traffic while I was going approx 35 mph. When the downshift happened the tired locked up and the rear end slid sideways. I was able to regain control; however, as I stepped on the accellerator, the truck bogged down for a few seconds before reving to high rpms and shifting roughly and then went into a mode that only allowed the truck to move between 3rd and 5th gears.

The lead frame on my truck was experiencing issues. The truck would intermittently randomly downshift at high speeds or get stuck in one gear. I was going 65+ mph on the freeway and and my truck shifted to second gear with no warning causing me to swerve and slam on the brakes. Other times my truck did it on surface streets. There were no warning lights or anything to let me know it would happen. After it downshifted, the wrench popped up on the dash, my speedometer went to 0, and my odometer read blank. Forcing me to pull over, restart the truck, in order to get it out of limp mode to be able to make it home. I took my truck to Ford of valencia California where they inspected the truck and confirmed it was the lead frame. The issue was that at the time the part was on an 8 month back order so my only option was to replace the entire valve body instead of only the lead frame. My truck was no longer under the recall and I was forced to pay for this out of pocket less than a month of purchasing the truck from a used dealership. My truck was only inspected by Ford of valencia and no other agencies. Since this truck was my only form on transportation, I could not wait the 8 months for the lead frame to come in and had to pay out of pocket for the new valve body.

Driving down the expressway yesterday doing approximately 72 miles per hour and the vehicle does a hard slam down to first gear and picks right back up to 6th. Now my concern is not only for the lead frame issue, but my transmission is being damaged every time this continues to happen. Since Ford was not able to even look at my car until June 2023 (its currently April 28, 2023), I elected to take to a reputable 3rd party repair shop. At which I was told that the parts on are order and on an "undetermined time" for receiving and im stuck driving my vehicle with these issues, that Ford is aware of, that are becoming a bigger safety issue each time I drive it. Disappointing to say the least. Ford cant build quality trucks. They dont own up to their known safety issues. They cant even schedule to see them in a reasonable timeframe. They dont have adequate parts available. And us consumers are stuck footing the bill and inconvenience. Do better Ford. We are all disappointed.

Driving down the expressway, doing around 70 mph and the vehicle randomly jumps to first gear and brings the vehicle to a near halt in less than one second. It happened during rainy conditions and luckily there were no vehicles nearby or I may have struck one of them. At least once per day the vehicle does this at some capacity. No service lights or check engine lights are present.

While driving 75mph transmission down shifted unexpectedly to 1 gear. Once I got it home had codes checked called for they stated my truck wasn't covered under recall that is out there for 2011 Ford f150 doing the same thing.

I was driving, luckily at a slow speed when my trucks transmission without warning down shifted into first gear.

The transmission seem to not want to switch gears. It lost power in the middle of the road. Haven't seen a dealer. Havent been inspected. A large wrench appeared and started becoming erratic. Put my scan tool on it and retrieved code p0720.

I am getting a p0299 code truck and according to research, this is something to do with the turbo. It is causing my truck to lose power while driving. I have had it parked since then.

Truck downshifting while driving and looses mileage speedometer and gets stuck in 3rd gear and shifting hard. Start truck up it does good for like 5 mins then downshift and pops into 3rd and get engine light and wrench light.

My truck has been shifting hard. . Or taking a very long time to shift into gear. When I put the truck into reverse it doesn't indicate/light up the r-reverse light on dashboard which is dangerous not knowing what gear the truck is actually in. . After quite some time it will slam or thud hard into reverse but still doesn't illuminate on the dash. . . Then when switching into drive it slams very hard into gear. My acceleration has also been acting up and does not accelerate normal anymore. It's very sluggish and slow to get going which is very dangerous sometimes when entering a highway. I've also been going 40-50 mph and suddenly I lose power and my truck slows down and I have no control over it. . Hitting the gas only revs engine but does nothing. My reverse lights don't work sometimes either and my rear window has also quit working. I have contacted the locao Ford dealer about these issues and the person was not only rude but was without doubt trying to rush me off the phone and told me they were booked up for many weeks and it'd be awhile before I could get the truck looked at. . . I bought thus truck in November 2019 and had taken it in for a recall that they had to do a quick reprogramming. . . Come to find out there was also at the time a safety recall which "expired'" at 10 years or 150000 miles which is imo total nonsense and unprofessional of Ford to not make this a real recall that they are required to fix knowing the many issues thousands of vehicles are having due to there negligence when they were built. It's not right to have there customers pay thousands out of there pockets to replace parts that are known to quit working properly and cause many safety issues for people driving the faulty vehicles. We are already paying monthly payments and the only thing the expired safety compliance/ not actual recall is doing for Ford is making them lose loyal customers. I truly worry about the unsafe occurrences that may happen with my child in my truck now and it's not right.

Lead frame in transmission, causing downshifts in my truck and cruise control and speedometer shut off. I noticed theres a recall for issue but only on some. I'll be driving and all of a sudden wrench pops up and downshifts and dash components quit working and only runs in certain gears. Also had to put 2 timing chains in,both at 50000 miles, 3 vacuum pumps for the brake system which both of these were recalled but only for 1 one each item. . I work for Ford and try a d support them but just bought vacuum pump 3 weeks ago now this a d pump was 550$ no brakes without it. . That also goes out right now. Ty.

The contact owns a 2011 Ford F-150. The contact stated that while driving 10 mph, the speedometer failed to properly show the speed after exceeding 10 mph. The contact stated that the transmission failed to shift properly. Additionally, the vehicle was slow to accelerate. There were no warning lights illuminated. The vehicle was taken to the local dealer where it was diagnosed the molded lead frame needed to be replaced. The vehicle was not repaired. The contact stated the failure was related to NHTSA campaign number: 19v075000 (power train). The manufacturer was contacted and referred her to the NHTSA hotline. The approximate failure mileage was 75,000.

Ford has a "safety compliance" which has an expiration date of 10 years or 150,000 whichever was first. How is that even allowed? a major issue with the transmission range sensor which doesn't show a driver what gear there in. . . The lights all disappear so driver doesn't know if there in p, r, d, n, etc. . . Its extremely dangerous! it also forces my truck to go into limp mode which is very dangerous especially when driving down a highway at 55. The truck was "reprogrammed" a few years back to stop the sudden downshift issue from occurring but it didn't eliminate that problem. Do you know how scary it is to be driving down the highway at 55-60 with your toddler in the back. . . And then your truck suddenly on its own shifts down to 1st gear and there's nothing driver csn do but hope they don't hit or get hit by another vehicle?? these are just a few major issues I've had with the truck since buying it 5 years ago. I've barely drove rhe thing since the sudden downshift occurred and could have killed my son and I. The back window quit working. The transmission seems to have alot of issues and I was told because I am past 10 years. . Yet still under the 150,000 miles id have to pay full price for the backordered part through Ford only which was quoted at $470. 00 and that doesn't include any labor. Ford is letting people down majorly. I wish I never bought the truck because it was so exciting to finally have a nice vehicle only to be let down in numerous areas. I drive my 1989 suburban more than my truck due to safety issues and because I am not going to spend thousands on it for an issue that they know has been a major problem for so many customers but yet it wasnt ever an official recall. Total bs!! I can't even believe they can get away with such issues. It's appalling and I'm beyond disappointed with my basically useless truck.
