2017 Ford F-150 Engine Problems

*What component or system failed or malfunctioned, and is it available for inspection upon request? -The vehicle downshifts suddenly and hard-shifts down on its own. It is worriesome as it randomly happens and oftentimes at high speeds. Yes it is available for immediate inspection. *How was your safety or the safety of others put at risk? -On more than one occasion the vehicle has suddenly downshifted causing a hard noticeable jerk at random speeds. I am worried that at higher speeds it can lockup and cause a serious accident with my kids in the car. *Has the problem been reproduced or confirmed by a dealer or independent service center? -I have taken it to Ford on several occasions in the past but said they didn't notice anything, but I recently took it again and explained the downshift and hard-shift again and now they told me it needs a full transmission replacement that would cost close to $8000 dollars. *Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? -The vehicle has been taken to Ford on multiple occasions but they did not find any issues at first. I took it again as it has happened more often and now they tell me it requires a full transmission replacement. *Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? -The issue first appeared last year, I took it and told them that it had a suttle jerk and asked them to inspect and if there were any recalls. No warning lights. *I am seriously concerned for my safety, it is my only good vehicle and worried it can cause an accident with my kids in the vehicle.

An unknown coolant leak with my 2017 2.7 engine causing sufficient damage due to a manufacturer error and needing a new engine. I had several people tell me this is a common issue with 2.7 engines.

While driving my truck roughly 60 mph, I experienced a sudden and uncommandded shift from 6th to 1st gear for roughly 3-5 seconds. When this occurred the engine RPMs jumped up to near Red Line and I experienced a rapid deceleration. I was driving on a dry road with new tires and did not experience any wheel lock up or skidding. However, this could have very easily posed an extreme safety hazard to both me and other drivers around me had I lost control of the vehicle which would have been highly likely in less optimal conditions. The problem has not been reproduced by a dealer or independent service center and the components have not been inspected. While the downshift was occurring there were some lights that flashed on the dashboard. I believe it may have been a check engine light, but my focus was on maintaining control of the vehicle so I did not have time to focus on the lights. Once the engine shifted back to normal there were no remaining lights or cautions. The symptoms of this incident very closely match those discussed in the ongoing Investigation EA26001.

I live in Canada.While driving, my 2017 Ford F-150 with the 6R80 automatic transmission suddenly shut off without warning. The vehicle lost power while in motion, creating a dangerous situation. The incident was accompanied by multiple powertrain fault codes (5 P-codes). This appears to be related to sudden transmission faults and loss of gear position. No prior warning lights before shutdown.

Check engine light for code for P2007 for an intake manifold runner control valve failure resulting in loss of power. This is well known issue for this era of engines. The runner control valve rod breaks and can not be repaired. The entire intake manifold must be replaced at a cost over $2k.

2017 2.7L F150 6 speed transmission. After an hour of drive time transmission vehicle got stuck between 3rd and 5th. If continued to drive it would go into “limp mode” stuck in 3rd gear and unable to accelerate.

My Ford F-150 is having issues that is known to Ford about the cold rattle start which consists of the cam phasers are defective and can cause serious damage to the engine. At the time Ford had put out some customer program and my vehicle has only got 36,000 miles on it and the problem has now just started. I called ford service center and the service man was surprised that mine started going bad at such a low mileage vehicle and pretty much said theirs nothing they can do except pay thousands in repair. And I explained to him that when ford had sent the customer program out my vehicle wasn’t encountering any issues and he said they cannot offer that to me. My truck is in very new condition don’t drive it much so now I’m stuck with a new truck where the engine can die out at any given time. Ford knows this was a problem from the beginning so why didn’t they recall this as this is a very expensive repair. I think this should be taken care of by the dealer as I have a new truck then have to turn around and spend 5,000 dollars on repairs

I own a 2017 Ford F‑150 equipped with the 3.5L EcoBoost engine. The vehicle currently has approximately 70,500 miles. The dealer diagnosed a ticking/rattling noise coming from the top left side of the engine near the timing cover. Using a stethoscope, the technician determined the noise was related to the timing system. The dealer recommended replacing the cam phasers, timing chain guides, and timing tensioners, along with all related seals and gaskets. The total estimated repair cost is $5,957.08. After researching the issue, I found that this cam‑phaser rattle/ticking problem appears to be widely reported by many owners of F‑150 trucks equipped with the 3.5L EcoBoost engine. I also learned that Ford Motor Company issued Customer Satisfaction Program 21N03, which extends cam‑phaser coverage for certain vehicles with this engine. However, when I contacted Ford Customer Service, I was informed that my VIN was not included in the program and that no financial assistance was available. I was directed back to the dealership. Given the relatively low mileage of the vehicle and the number of similar reports from other owners, I believe this may represent a systemic defect in the cam‑phaser/timing system. I respectfully request that this issue be investigated and considered for a recall or broader coverage program so affected owners are not responsible for costly repairs caused by this defect. If the cam‑phaser or timing components fail while driving, it could potentially affect engine performance, create a stall condition, or lead to loss of power, which may pose a safety risk.

Complaint Summary (What Happened): The cam phasers (variable camshaft timing system) failed on my 2017 Ford F-150 4x4 with the 3.5L EcoBoost engine. This is a widely known issue on these engines. The failure causes a loud rattling/knocking sound during startup and can lead to engine timing problems or internal damage. My truck only has 108,000 miles, has been well maintained, and is just outside of the extended warranty coverage Ford issued for this exact issue. Safety Risk: The cam phaser failure causes erratic engine timing, which can lead to power loss or stalling during operation. This creates a safety hazard while merging, towing, or driving at highway speeds. The loud knocking sound and hesitation also distract the driver and reduce confidence in the vehicle’s reliability and acceleration when needed for safety. Problem Confirmation: Yes, the problem was confirmed by a Ford dealership. They diagnosed cam phaser failure and quoted approximately $6,300 for the repair. Inspection: The vehicle has been inspected by a Ford dealership service department. Ford Motor Company was contacted but declined to assist financially since the issue occurred just after the extended warranty expired. Warning Signs: No warning lights or messages appeared before the failure. The first symptom was a loud rattling/knocking noise on cold start, which worsened over time. The issue started around 85,000 miles. The check engine light just came on at 108,000 miles. Availability for Inspection: The failed components remain installed on the vehicle and are available for inspection upon request. However, I am looking to get this fixed as soon as possible.

There was an unknown problem with a fuel injector that resulted in the a vapor lock of the engine. This incident happened in traffic while idling at a stop light. There was zero stress on the engine at the time of the incident. This was a busy intersection, and I could have been pushed into oncoming traffic. There were no warning lights(check engine or otherwise) indicating and engine related failure or that an issue could be present in the fuel or engine systems. Upon trying to restart after what appeared to be a simple stall out, all indicator lights were on and every warning possible was present My local service center reviewed the truck and did confirm the resulting issues. They have also advised they would have expected such issues to trigger a warning light. I believe this was a catastrophic failure on Fords part and as a result has landed me as the consumer with concerns for the safety and a large bill for the work needed just to get it back on the road.

Engine exhibits severe rattle on cold start ups. Occasionally a loud rattle occurs at highway speeds at random times. After research, I discovered Ford was aware of the failure of the cam phasers that produce this issue.

My vehicle cam phasers went bad. Cost to repair is in the upwards of $5000. Called Ford was unwilling to help pay for repairs. There was a TSB put out a year or so ago that stated that FORD knows about the cam phaser issue and would help pay for repairs. My cam phasers went bad this week and if not fixed can cause complete engine failure. They have apparently redesigned them a couple of times. I just don't get it, if it's a known defect in the 3.5 EcoBoost engine s how come there is no recall on them. I'm not the only one complaining check the ford forums online. I have to get it repaired or pay for a whole new engine. Plus I have an active recall on my braking system for about9 months know.
