I-??ve taken the truck to a ford dealership and after running diagnostics they-??ve told me they have to replace the whole transmission the problems I reported before they ran diagnostics were that when driving on hills or moving from a stop to get into traffic the vehicle will go from 4th gear to 1st and won't accelerate. When going into reverse it buffers and takes a second to engage in gear. After this happens I'm alerted with "Powertrain system fault" This causes a safety issue for me and others because on hills it won't accelerate and it rolls backwards. From a stop trying to get into traffic it won't move and becomes a collision waiting to happen. Before I took it in to a Ford dealership to look at, these problems became an everyday issue and the problems always happen and I was forced to not drive it to avoid further damage. The only warnings are "Powertrain System fault" No symptoms and first appeared late June of 2024.

I am writing to formally submit a complaint regarding persistent and significant issues with the cam phasers in my 2017 Ford F-150 3.5 EcoBoost. I purchased the vehicle in December 2022 with 70,000 miles on it. Since then, I have experienced ongoing cam phaser problems, which have led to considerable inconvenience and expense. In February 2023, with 82,000 miles on the vehicle, I took it to a dealership for diagnoses. Unfortunately, this repair was quoted at $8,000. The repair involved: -??Checking engine light diagnosis and verification of cam phaser failure. -??Removal and replacement of timing chains, phasers, chain tensioners, valve covers, gaskets, and other related components. -??Reinstallation and testing to ensure the problem was resolved. I believe Ford should cover these costs since the cam phaser issue is widely known and documented as a design flaw in the 3.5L EcoBoost engines, particularly those produced before 2021. Ford acknowledged this issue and updated the cam phaser design in 2021, but many owners, including myself, have experienced failures despite adhering to recommended maintenance and service procedures. I urge the NHTSA to investigate this matter further and hold Ford accountable for the costs associated with these known defects. Thank you for your attention to this matter.

We have purchased this vehicle as a used vehicle and shortly after we purchase, the check engine light came on. We were advised to replace some solenoid(s) on the engine but that did not address the issue. The technician advised that we can continue replacing parts in the engine that would total around $3000 but there is no guarantee that it will address the issue and the most common fix they had was to replace the engine as this seems to be a common problem around F150 owners. We have received a second opinion from a local Ford dealership and they recommended replacing the engine as well which we ended up doing.

- Draper, UT, USA

Engine has began making lots of noises such as ticking and banging. Loss of power when driving the vehicle, extremely high fuel consumption resulting in maybe 10mpg with an 2.7 eco boost engine. Every start up of the vehicle results in large clouds of blue smoke emitting from the exhaust. I believe my engine is having the same failure as the new recall and my vehicle shall be included even though it-??s a 2017. Why is mine not included when all the signs are pointing to the exact same issue. For the exact same engine

After researching, I found multiple videos on YouTube and hundreds of replies saying that people have had the same problem and don't know why there is not a recall on this problem. 2017 ford 3.5L eco boost engine has plastic valve covers that crack and leak oil(dangerous due to flammability). I found this problem since I was researching a vvt solenoid after scanning and finding code p0022. I have not replaced the solenoid due to this problem. If the valve covers keep cracking, this code will continue to pop and it will be an endless loop of replacing parts. Please help. Pictures don't load. Please reach out if you need any additional information or closer up pictures. I can provide anything you need.

I have defective Cam Phasers for the second time resulting in rattling on startup. For the first event, the issue was handled under warranty. I understand that the cam phasers have been redesigned and he old design was apparently installed in my vehicle. This repair is extremely expensive and even, Cynthia, the Ford Cust Svc rep stated that this is a very common issue. The second event started [XXX] with about 125,000 miles on my odometer.

My F150 has an inherent design defect which makes them predisposed to leak coolant, including allowing the coolant to seep into the engine cylinder, which causes overheating and cylinder head cracking, and can cause the engine to misfire, suddenly stall, or even catch fire while driving. My truck currently has this issue it have white/gray smoke coming from the exhaust and has a coolant leaking issue causing it to come out of the tailpipe. This is 100% a manufacturing issue. I have always had my maintenance done at the dealership, examples of oil changes, and things like that. I have owned the vehicle since brand new engine issue is at no fault of mine.

My F150 has had the VCTS Units replaced four times. Two times at my expense costing me over $2000 each time. Ford fixed the problem under warranty once while it was still under warranty. They also did a reprogram that was to fix the problem but the problem did come back. I have now had to replace the VCTS twice at my expense for a total of four times since purchasing the truck and each time I am told the new parts are the fix. The second problem is the transmission slams out of gear while accelerating to pass other cars. Truck started to jerk and stop and shift sporadically into different gears. attached is one receipt. More are available. I will have one more after today's submission for nearly $2000 is repair for the same fix in under 50,000 miles since the last fix.

The Camphasers on my vehicle do not work properly. This component of the engine is vital to acceleration, and if they go out, acceleration is delayed. This makes it very difficult to operate, especially on highways, interstates, and other major roadways. The 2018 Year make of this same vehicle has been recalled for the same issue. Though it is the same engine (prone to the same issues), it is a different year, which means I cannot get my issue fixed.
