My truck stalls at a low rate of speed when driving in traffic. My truck is available for inspection at most any time and I have not notified any party but NHTSA. There were no warning lights or messages to indicate anything.

The exhaust manifold have warped, up due to lack of bolting down properly from the factory, and it is a known fact there are many other vehicles with the eco-boost that are having the same problem as I am 3.5

Vehicle shudders and stalls occasionally especially after a period of driving.
- Luling, LA, USA
Vehicle shuts off when in idle. Happens more often during a long drive. I have taken this vehicle to Firestone and a Ford Motor Company Service shop to have it repaired. Mechanics state that they are not able to replicate the issue and cannot do anything because the check engine light is not on. Considered about safety factors of vehicle shutting off when making a left turn and being hit by on coming traffic. Has been occurring for last 15,000 miles.

I was cruising on the highway normal speed them out of nowhere, my engine lost power and then a hill decent fault warning popped up. I pulled over then when I came to a complete stop my truck was shaking like if it had a misfire. So then I turned it off then back on. It turned back on on the first try but it struggled. When it turned on everything went away like nothing happen. Warning lights and the shaking went away.

The contact stated that the the engine vacuum pump was also replaced; however, the failure persisted. The contact stated that no oil leaks were visible underneath the hood of the vehicle. The cause of the failure was not yet determined. The local dealer was not contacted. The manufacturer was notified of the failure. The failure mileage was 190,000.
- Gordon, WI, USA
While driving vehicle jerked and engine shut off. Gas pedal was unresponsive. Flashed engine too hot and hill start assist disabled. Brought vehicle to a stop and engine idled rough before it stopped restarted vehicle ran in limp mode for approximately 5 minutes before I restarted again. No check engine codes to help diagnose. After second restart truck runs as if nothing happened. This has happened twice now with kids in the vehicle. Not safe while driving down a state highway.

Driving home form work I started getting an exhaust smell, kept driving and once I came to a complete stop at a light my entire cabin filled with exhaust white/blue smoke. I pulled over to check it out, opened the hood and the exhaust was coming from the back of the engine. A wrecker driver pulled up behind my truck, got out with his fire extinguisher for safety. He is the one who told me to look into the manifolds warping or the bolts breaking. The wrecker driver said the smoke in the cabin is carbon monoxide and not to transport and small children. The rest of the day, I had severe headaches. I took it to a shop and they have told me I will need new manifolds and gaskets and potentially a few other gaskets when removing the turbos. They also said this could have damaged my turbos and may lead to other exhaust issues, vehicle performance issues and definitely will not let my vehicle pass the emissions test in Texas. This appears to be a Ford design flaw and hopefully a nation wide recall can be implemented. The shop also recommended not to drive it because the cabin filled with smoke or rather a cabin full of carbon monoxide. This could cost me over $5000 to replace all part. Something needs to be done by FORD to fix this issue. I will have to find a way to pay for this as having a vehicle to and from work is necessary. My daily round trip to and from work is 80 miles.

Hill Start Assist Not Available is the associated light. Component replacement: Throttle Body Assembly. I was driving down the road and vehicle caution light came on above, in addition it caused me to have zero throttle pedal control. This occurred out of nowhere and I needed to glide into and off the road to luckily a pull off area. I shut off the truck, and restarted light went away. I thought it was a fluke. I continued and a mile later same exact issue, light came on, and I was going down a hill with no throttle control only brake and steering control, all the while passing vehicles and pulling over by a busy intersection with multiple lanes. I then pulled over and had to have my vehicle towed costing me $320. On top of placing myself at complete risk, if there wasn-??t a spot to pull over to, and/or I was going up hill, this would have caused a crash with other motorists and needs immediately fixed. On top of the tow bill, I had to pay $271 for throttle body assembly and associated gasket. This on top of diagnostics $90 and labor associated. I have watched YouTube videos of others having the hill start issues, but this issue occurred out of nowhere and occurred frequently and on the road. Truck has around 125,000, never been involved with a crash of any sort, and this issue should be recalled. I request a refund at the very least from Ford for part and labor and I strongly feel this is the least they should do for putting my life at risk.

I have had two problems worked on by my dealer and neither of them were fixed. The first problem is a leaky oil pan which they attempted to repair the leak 3 times but it still leaks. This may not be a safety recall but I do feel like it is a hazard and I would bet there are probably 1/2 of the 2015-2017 Ford F150 owners with the 2.7 engine with the same problem. If nothing else I would say this is a environmental issue. The second problem I have reported to my dealer is the very poor vision with the back up camera at night. I had to leave my vehicle with the dealer overnight to have the problem looked at but they were not able to fix the problem and did say the night vision is not good.
- Pratt, KS, USA
The contact owns a 2016 Ford F-150. The contact stated that the check engine warning light illuminated. The vehicle was taken to the local dealer where it was diagnosed and determined that the cylinder head needed to be replaced. The vehicle was taken to an independent mechanic who replaced the engine however, the failure recurred. The manufacturer was notified of the failure, but no additional assistance was repaired. The failure mileage was 56,749.
- Fremont, OH, USA
Had multiple leaks from both driver and passenger side exhaust manifolds cause by broken stud bolts. This resulted in loss of power and emissions.
- Cheyenne, WY, USA
Having a horrible screeching sound and after being diagnosed its the exhaust manifolds warping on both sides by the turbos. Local shop is telling me this in a known issue and cannot figure out why Ford has not addressed this issue due to it being a emissions issue technically and they have replaced several for same issues.

The exhaust manifold system on my F-150 failed and the Ford Motor Company is making me pay for repairs that costed approximately $4,000. At the time of repairs my truck had around 78,000 miles and yet the Federal Emissions Warranty is supposed to cover my vehicle for 80,000, miles or less for components that could adversely effect the vehicle's emissions status while in the continental United States. I have been bringing my vehicle to Ford-Service for it's regularly scheduled maintenance intervals. I have been maintaining my vehicle in accordance with the Ford Vehicle's manual for 2016 F-150. Failure of the F-150 exhaust manifold system is common on Ford Vehicles with the 3.5L Eco Boost Engine. This is due to the metallic warping of the cast iron manifold system over time. To address this issue, Ford has issues a 2021 Special Service Message Sep 1 2021 2979 - 2015-2021 Transit - 3.5L EcoBoost - New Exhaust Manifold Part Numbers - Built On Or Before 01-Dec-2020. The proper repair and replacement parts calls for stainless steel parts that will not warp over time. Failure of the existing manifold parts on these engines could result in the unplanned loss of these critical emission components directly onto the road and into the path of other drivers while operating the vehicle. Ford should be issuing a recall in addition to it's already published Special Service Message for these components so that the safer components can be installed on all affected vehicles. If Ford does not feel any pressure from the NHTSA or any other federal agency in regards to vehicle safety, then it will take a series of tragic accidents involving emission component failures and personnel death/injuries to get the proper amount of attention to force a recall. This is my attempt to notify the NHTSA of a possible critical safety flaw in their 3.5L Ecoboost designs and to get Ford to issue a recall as soon as possible, before getting into extremis.

Both exhaust manifolds have broken manifold studs at 95,000 original miles. This has caused the manifolds to warp and potential leak exhaust into the passenger compartment. Both exhaust manifolds are leaking exhaust at the cylinder heads. The vehicle is currently at my mechanic. His estimate for the repair is $2,700.
- Chassell, MI, USA
Exhaust manifold failure on an F-150 with a 3.5L Ecoboost engine with only 65000 miles. Exhaust fumes enter the truck cab when the engine is running and the truck is stationary. One exhaust manifold was replaced under an emissions system warranty. The other is also leaking at about 70000 miles and Ford doesn-??t think they need to replace it as a manufacturing design issue.
- Tyrone, PA, USA
Truck exhibits an intermittent lack of engine RPM when coming to a stop while towing. Engine actually dies at stop sign upon exiting interstate. will start and die repeatably until accelerator is depressed slightly, and RPMs are kept to 1,000 or more. Was not a serious problem until I got caught in bumper-to-bumper traffic on I25 north out of Denver. I could only operate with left foot braking and right foot keeping RPM above 1K. Three days at dealer with no luck. I have discovered TSB 18-2249 and 22-2264 that addresses problem to 2018 and 2019 but no mention about my 2016 F150 2.7L.
