2017 Ford F-150: engine failure

Filed Aug 27, 2026 · Engine · CA

Not sure if I can file an issue for this, but I wanted to let you know that a Ford Safety recall caused other issues after it was applied. In late July 2026, my son received a Ford safety recall notice (Recall #26S28) for his 2017 F 150 requiring a PCM software update. I brought the truck to Crown Motors in Redding on August 11th for the recall service. Before this appointment, the truck had no performance issues. Immediately after picking up the truck, a noticeable pinging sound occurred under acceleration. I returned the vehicle on August 12th, where Crown Motors confirmed the issue and advised spark plug replacement. This did not resolve the problem. I was also told that continued driving could damage the engine, so the truck remained at the dealership. Over the following days, Crown Motors worked with Ford engineering and repeatedly attempted software-related fixes. Crown staff informed me they believed the recall update caused the issue, and the first internal Ford team reportedly agreed. However, on August 25th, Ford’s second internal review determined the software update was not responsible and stated that all repair costs would fall on me—despite the clear timeline showing the problem began immediately after the recall service. Customer Service provided no assistance and refused to escalate my concern. As a result, my truck is currently non-operational, Crown Motors does not have a fix, and Ford will not cover repairs triggered only after Ford’s own safety recall. I believe the Spark Knock issue is an additional safety issue caused by the PCM recall update that was I was told could cause engine failure.

At 87,336 miles, my 2017 Ford F-150 (3.5L EcoBoost) would not start. The engine clicked and buzzed but failed to turn over, leaving me stranded with no warning. There was no prior check engine light. I brought the truck to Roy Hendrick Automotive in [XXX] (Invoice XXX, completed 03/05/2025). Their diagnosis determined the cam phasers and timing components had failed. The shop performed a full timing chain and cam phaser replacement, including both camshaft sprockets, timing chains, tensioners, timing chain guides, variable timing solenoids, water pump, seals, gaskets, and spark plugs. Total cost: $5,449.36, entirely out of pocket. This is a serious safety defect. Cam phaser failure in the 3.5L EcoBoost can cause catastrophic loss of engine timing, resulting in sudden engine stall or failure to start. A stall at highway speed, in an intersection, or while merging creates an immediate risk of collision, serious injury, or death. Even a no-start condition is a safety issue when it strands a driver in an unsafe location. I use this vehicle daily to transport my two young children (ages [XXX] and [XXX] ) to and from daycare. A sudden engine failure while driving with them in the vehicle could have had fatal consequences. Ford's 3.5L EcoBoost cam phaser failures are extensively documented, with numerous TSBs and owner complaints on file. An engine should not require over $5,000 in internal timing repairs before 100,000 miles. Ford has failed to issue a recall or provide an adequate remedy. I am filing this complaint to ensure the federal safety agency has a complete record of another 3.5L EcoBoost timing failure that put vehicle occupants, including small children, at risk.

I took my 2017 Ford F150 XLT super cab 4 x 4 into Matthews-Currie Ford dealership. It was diagnosed unsafe to drive. They replaced the transmission & driveshaft. The truck still was not functioning correctly. Took it back into the same dealership where they determine the engine was also bad. They ordered a junkyard engine that leaked all of the oil due to a loose or faulty oil pan plug. & had the truck in their possession for well over two months. The truck still does not operate correctly & they are refusing to stand behind their work. No warning lights. No indications of problem other than how it drove. There is no cooperation from another dealership due to this one working on it prior. I pay for an extended warranty that nobody wants to honor due to the fact that this dealership has worked on it and they don’t want to get involved after having all of this work done by somebody else. My safety was put at risk due to the fact that the driveshaft & transmission & engine were all failing at the same time & the dealership proved that by not letting me leave with my vehicle. Once they diagnose the issue. They said it was on roadworthy. This put me in a position of having to rent vehicles out of my own pocket & be reimbursed 50% of the cost of rental. They had the truck returned to them due to problems. They did not diagnose when I asked them to do a full diagnosis of the vehicle when I noticed it had an immediate problem one day into owning it. This worries me because not only do they want to not honor their work. They have caused additional electrical problems to the radio. & the air conditioner not cooling as it did before they replaced the engine. They stated maybe I should try to buy a more extensive Extended Warranty & they would consider fixing it. They treated me very unprofessionally & could not give a descriptive explanation of where they got the replacement used engine who rebuilt the transmission & why the electronics & air conditioner failed.

The oil pan has a rtv gasket from factory and started leaking, I’ve replaced it twice and is still leaking. It’s expensive and cumbersome. It runs the risk of oil starvation, this would cause catastrophic engine failure, ford has TSB for this issue. UNKNOWN UNKNOWN

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.

- Cam Phasers failed. Ford installed faulty Cam Phasers in their 2017-2020 Ford F150 trucks that cost $5,700 to fix. It is a very well known issue. No, you can not inspect the issue due to the fact that you have to take apart the engine to get to them. - When Cam Phasers fully malfunction the engine is blown and will need to replace the engine. - Yes, it was diagnosed by a dealership - No warning lamps. There is a rattling sound when starting the vehicle and after research there is a ton of videos with the exact same thing happening to others.

Internal coolant leak issues leading to engine failure. Know defect publicly acknowledged by Ford as there is a class action lawsuit for the later models, but same engine (2.7L eco boost) My gauges do not register that my coolant is low or empty. I have taken it to the dealership twice in 6 months for the complaints of coolant loss. An independent mechanic suspects the same issues as the known defect leading to engine failure

My apologies, I sent prematurely, case number 11664674 is already open, but I wanted to add to it. My 2017 Ford F-150 with the 2.7L EcoBoost engine has experienced recurring coolant loss and is now showing signs of internal engine damage. I initially reported the issue to the Ford dealership in November 2024, but no issue was found. On May 23, 2025, the dealership told me I need a new engine. My independent mechanic suspects cracked intake valves or internal coolant intrusion — a known defect in the 2.7L EcoBoost engine. This appears to be the same issue identified in class action lawsuits and previous the federal safety agency complaints. I feel the vehicle is now undrivable due to my fear of imminent engine failure. My extended warranty expired in December 2023, but the problem started well before that with white smoke coming out of the tail pipe upon cold starting. I am requesting the federal safety agency investigate these recurring issues, as this appears to be a widespread and unsafe defect affecting multiple years of the Ford 2.7L EcoBoost engine.
