1) due to a poor design, myself and multiple others users have had issues with faulty / poorly designed coolant hoses. These hoses would randomly disconnect or spill coolant. Currently, my truck is leaking coolant and even after replacing the hose, it is still occurring. See below link to thread: - https://www.F150forum.com/F70/2011-5-0L-coolant-leak-252081/ 2) it is a common issue for the back window to randomly blow out due to issue with design the heated windows. This could cause a hazard since the driver could be distracted when the window blows out. See below forum issue: - fordauthority.com/2017/12/another-Ford-F-150-owner-claims-the-rear-window-shattered-despite-no-impact/ - https://www.F150forum.com/F38/exploding-rear-window-145329/ photos are in the forums.

Having lots of problems with misfires. Engine shakes and shutters during idle. If I try to pass a car on highway the truck will go iino a severe shake and then will not accelerate. Goes into limp mode and engine light comes on. Have to pull over and shut the truck down for a couple of minutes and then start back up. This is a constant problem. More pronounced during rainy days. Have replace coil packs spark plugs map sensors and still have not solved problem.

I took my truck to oil change next day I noticed some smoke from the hood, I think, is just some oil spill somewhere and it is all. But the smoke keep appearing every morning, I start using the heat and the smell of oil burning was inside, so I stopped and check what is going on I don't see anything, so I decided to take back to the dealership so they can check what is going on, before I make to the dealership the engine light starts blinking and the truck shaking when I get there I splain everything to the guys, they check everything and tell me the turbo has a like. They supported getting the truck fixed on next week, let's see how everything turns.

When I am driving, and I attempt to accelerate(press gas pedal) the engine loses power. I then have to coast to a stop and put vehicle in park, turn engine off and restart, and drive on. Sometimes it does it again.sometimes it doesn't. it's does it when I'm on road ways. Dangerous it happens in traffic.

While in motion at highway speed (55-70mph) and city speed (20-35mph)the vehicle lost power and/or hesitated upon acceleration several times over the course of 3 days the middle of May 2018. After diagnosis by Ford dealership that timing chain on the ecoboost engine with only about 75,000 miles on it required replacement. About 5 days after timing chain replacement the hesitation returned and upon diagnosis by Ford dealership it was determined the phasers were bad. Despite numerous complaints and reports of this occurring in 2011-2015 Ford F 150 ecoboost models in America and Canada Ford refuses to admit there is a defect. While maybe not directly a safety issue I believe it is as one of the failures occurred on the interstae in heavy traffic while passing a semi truck and power was lost and evasive action had to be taken to avoid a collision due to the timing chain power failure. Can't argue with what actually happened, if that isnt a safety concern for Ford or the NHTSA I don't know what is. Defective system for 2011-2015 Ford F150 ecoboosts

While accelerating up a hill traveling about 45mph the vehicle suddenly lost power and went into "limp home" mode. Fortunately I had enough momentum to make it to a side road as the country road had no shoulders. After shutting off the engine and restarting, everything ran normally again. Potentially very dangerous situation. Online search points to possible issue with the electronic throttle body.

Vehicle develops a coolant leak from the quick connect fittings on the turbo. The leak started at 30K miles. Fittings circled in green leaked first. Then the blue ones began leaking at 31K miles and when repairing the ones in yellow were required to be replaced as well

- Kaneohe, HI, USA

Truck has 46665 miles. When driving first 10 minutes (city driving) vehicle shudders, shows wrench indicator and goes into limp home mode (no accelerator). Have to pull over, turn off ignition and restart engine. Problem code shows P2112 (throttle actuator control system...stuck closed). This may happen 3 times in first 15 minutes of driving, but then goes away when car warms up. I have also noticed abnormal exhaust smoke and bad gas mileage. Having truck go into limp home mode in middle of traffic is very dangerous.

Etb. We lost power on are 2014 F 150 eco boost doing 50 plus miles an hour.. out of no where it started to not accelerate and just shut down. Check engine popped on we managed to move to the side. It started up after two attempts then check engine light came on. It drove to nearest shop to have code checked they said oh its the etb.. that's recalled. So we explored and researching why it's not on recall. We were about a moment away from being slammed into the concrete medium from behind.

Engine coolant leaking from coolant recovery tank hose connection.

Turbo went in the truck which then cause engine and transmission damage. Mechanic says the engine, transmission, and turbos need to be replaced quoting over 10K. Also, a neighbor had a 2014 F150 do the same exact thing around the same mileage and I thought that was very odd.
