While driving the transmission would down shift from 5th to 1st and the speedometer would stop working. After doing research I found Ford issued the following recall safety recall 16S19 the intermittent output speed sensor (oss) failure may result in an unintended downshift into first gear. However after contacting Ford they said my truck was not covered under that recall. I brought my truck to the dealership and they fix the exact problem that was on the recall.

My name is [xxx], I own a 2011 F150 ecoboost. Over the past 4 years I have encountered and same issue with the engine misfiring due to moisture getting in the intake. Everyone dealership personal I've spoken with has confirmed that it's a known issue with that year and model and there is no permanent fix. However when the engine continuously misfires it calls for service on the truck and replacement of certain parts. I am filling this complaint because I do not believe this right that Ford should be allowed to ignore a known issue that has almost gotten myself and family into a serious accident on the highway. As well cost me money out of pocket to correct. I would like to see someone hold Ford accountable before this issue gets someone killed.

2011 Ford F-150 XLT supercrew 4X2. I was operating the vehicle in normal conditions earlier this week and noticed that the vehicle was not accelerating after pushing on the gas pedal. I had noticed this very intermittently over the past several months, but this issue was constant. There were no warning indicators, but when attempting to accelerate the pu seemed to be operating at about 30-40% of the expected performance level. I took into the Ford service dealer, northside Ford, and they mentioned it might be the PCM but they needed to start by replacing the O2 downstream sensor. They replaced the O2 downstream sensor and re-tested and it them indicated that the PCM needed to be replaced. The vehicle only has 112,500 miles so it seems odd that there was a recall (12V190000) but my vehicle was not included and it seems to be exhibiting similar problems. I would like to see if someone can look into the issue as I believe it has a similarities to the previous recalls.

2011 F-150 super cab 4X4 with an 8ft bed 3.5 ecoboost engine, driving down the high way 60 miles an hour engine threw a rod, it blew through the entire block causing an extremely dangerous situation, started checking around have found many complaints of the same thing in the 3.5 ecoboost engines, something about Ford using cheaper powdered rods, I'm not sure all I know is I had a perfectly good truck one minute and the next it's basically a loss, I just thank for no one was hurt.

When accelerating onto the highway the power shut down and the engine shaked violently and the engine light came on. Afterword I could not speed up pass 50mph. I pulled over let it rest for 30min and the engine light stayed on and I was not able to do any aggressive accelerations and could barely make it up hills.

Driving 2011 Ford F150 ecoboost on the highway on a 8 hr trip to reno from las vegas. Went to pass a large truck and experienced shaking and studdering. Had to back off as oncoming traffic was approaching. Had to back off and almost caused an accident in rainy conditions because another vehicle was behind me attempting to pass along with me. This caused swerving and hard braking by many vehicles behind that vehicle. Check engine light flashed but did not remain on. I later replicated this by doing a hard acceleration on a clear stretch of road same studdering and flashing light. Drove conservatively the rest of the way. In reno, I had the truck scanned at an auto parts store. No codes showed. Have not had an issue since. This could have killed people. The internet says this is a known issue to Ford on the early ecoboost engines having to do with faulty intercooler design which gathers moisture then blows it into the cylinders when accelerating. I live in the desert and so have not had this problem until that trip. They (Ford) have never notified me that this is a potential problem. There is a tsb for it but that won't help the large bill for the fix or the safety hazard this condition creates. This needs attention. At the least, Ford should notify owners that the problem exists, that it is a safety hazard and fix at no cost.

Recognized pattern failure. Excessive timing chain stretch on 2011 Ford F-150 XLT with 3.5L ecoboost motor. Tapping and rattling noise from the top front of the engine when first started, lasting for approximately 3 seconds. Vehicle well maintained and driven in normal fashion on paved highways. Odomoter ~86K miles. The owner contends timing chains in properly-maintained and normally-driven vehicles should typically last the lifetime of the vehicle (or thereabouts) unless a defect exists. The customer has discovered (unverified) that Ford Motor Company has revised the specifications for the timing chain mechanism on this motor in more recent model years, with redesigned chain and guides and updated part numbers. There is a risk of catastrophic engine failure at highway speeds leading to a substantial safety hazard with the vehicle no longer drivable. Ford has acknowledged the problem three times with tsb 14-0194, tsb 15-0131, and tsb 16-0027, but has failed to initiate a voluntary remedy outside of warranty coverage. Premature timing chain wear appears to be an increasing and ongoing problem on later model gasoline turbocharged direct injection (gtdi) engines. The customer raised the issue with both a local Ford dealership and with Ford Motor Company headquarters to no avail. Repair cost $2634.44 at Ford dealership. This apparent defect yields continuing and substantial profits for the manufacturer.

Ford F150 2011 ecoboost engine. In 2015, truck started to loose power going up hills or carrying a load in truck bed. Then the truck went into limp mode on highway going 70 mph.

Engine looses power and engine light and codes set saying timing chain errors. Same symptoms as before. Ford says truck is out of warranty and will not fix unless I pay.

Primary timing chain wear. According to tsb. 15-0044, the structure of the timing chain is inferior to the point it stretches. If it breaks, the engine will be compromised and a full re-haul of engines interior will be needed. A loud grinding noise is always heard upon startup in a "cold" start up.several complaints on line concering Ford's below standard of material / cost of any repairs. Also mentioned is after repairs are done, same trouble returns in short period of time after repairs. Unknown the affect the timing chain will have on vehicle if it breaks in transit. Note: As far as I can tell, the issue has started as soon as vehicle purchased reaches "out of warranty" mileage status.

According to the research I have done to this point the fist recall that I believe applies to this vehicle is tsb 13-6-8, and the 2nd is tsb 13-8-1. both of these symptoms are prevalent to my vehicle but Ford fails to act on this tsb and fails to make the necessary repairs that will remedy these issues. Once again this vehicle is now part of a field service action (15N05) for the electric vacuum pump, and will return the vehicle on 3/24/2017 to see if they will respond in this action, and once again bring these tsb's to there attention as previously done to see if they will repair the vehicle to an acceptable operating standard. If Ford fails to respond to the tsb's and to the field service actions, what are my options to see these repairs take place, and my vehicle is in a safe and proper working function?
