On March 30th I filed a complaint #11654561. Since that time the vehicle has progressively gotten worse. Traveling at approximately 55 mph the tires suddenly locked up/stopped rolling at normal speed, jerked the truck and I was flung forward. the vehicle would not go over 15 mph AGAIN! Then, on [XXX] I was traveling home approximately 65 mph and truck downshifted and wouldn't move beyond 20 mph. This is getting out of control that I continue to have transmission problems with this vehicle. Talking with a Ford representative he said many problems have been with the transmission conductor plate, there is a defect and having it replaced with any product other than the Ford piece seems to resolve the problem. This is incredible, Ford is telling me what the problem is and won't fix it. How many other people are going through this same problem and we as Ford customers...

2017 F-150 Platinum Supercrew 4WD Recently Purchased from dealership, drove for 2k miles and started having engine knock. Did research and found identical sound, Cam phaser knock/rattle. This is still a high priority issue and a known issue as it can cause engine failure and manufacturer is unhelpful and unwilling to investigate and/or offer guidance. I talked to dealership that preformed the “recall” previously and they stated that no part was replaced and ford issued a software update to use as a bandaid instead of a permanent repair. It will cost upwards of $6,000+ to repair through dealer and ford refuses to be of assistance. I am requesting that the NHTSA reinvestigate the issue and open back up a recall request to the general public due to it being a safety concern. If the engine implodes on the highway, it can cause a major accident and/or fatal injury to many...

Transmission will change gears while driving. I can be driving 45 mph in traffic, truck will automatically shift and I'm now going 15 and cannot speed up. There is no warning lites on dash before issue occurs. Called dealership who had no solutions to offer. I cannot be the only one experiencing this issue from reading online forums and Ford needs to be held accountable for faulty equipment. This is a safety issue in traffic for my family.

To Whom It May Concern, I am filing a complaint regarding a premature engine failure in my 2017 Ford F-150 Platinum (VIN: [XXX] ), which has only 88,000 miles and has been meticulously maintained at an authorized Ford dealership. Despite following all scheduled maintenance, I am told I must replace the entire engine for nearly $20,000. Over the past two years, I have spent over $2,000 on repairs (outside of standard maintenance), including replacing the cam phasers due to a known issue. After that, I experienced engine bank problems. The turbo was not properly reconnected during a later service, requiring immediate correction. The truck ran fine until one day, on a short 10-mile drive, I received a low oil pressure warning and had it towed back to Chapman Ford, where I was informed that the engine had failed. This failure is unexpected and unreasonable for a vehicle that has been...

The cam phaser broke down and would have destroyed the engine if left unattended. This could have led to the car breaking down in the middle of the road. Problem has been reproduce by Ford, this has happened with countless other trucks as well. The item has been fixed by Ford but costed $4000. there were no alarms, letting me know that this was happening, but there was a distinct sound when starting up my truck and accelerating my car. It made a rattling noise in the engine bay.

I have an invoice regarding multiple leaks on the engine, and loud rattling noise from the cam phasers. This engine is notorious to have these leaks from every forum I have read. It doesn’t seem to have a mileage relation either. The problem I have with this is that these leaking components can leak fast enough for a customer to not notice and can lose lubrication within the engine leading to premature wear and tear. The cam phasers have been revised but should all be replaced. If the cam phasers are in charge of timing control and valve train manipulation and if they fail they could throw the engine out of timing and cause a massive malfunction, bent valves, connecting rods, damaged pistons etc. this needs to be addressed as it is a lengthy and expensive repair. This effects all ecoboost engines. After multiple online chats, phone calls and 6...

Have had the rear door locks stop working during the cold, it would not allow the doors to shut and stay shut. I did have children in car seats in the truck at the time. After trying to get the locks to work for about 10 minutes they stared working again. Also have an oil leak that was discovered while having an oil change. I became aware of Technical Service Bulletin: 23/2083, NHTSA ID Number: 10233594 (Engine and Engine Cooling) and related the failure to the TSB. Called the dealership and they said they couldn't do anything about it because there was no recall for it. My truck is included in the vehicles from the Kansas and Detroit plants that are affected by a defective oil pan. The manufacturer is refusing to issue a recall.

My 2017 Ford F150 STX with 3.5L Ecoboost engine was recently noted to have a leaking oil pan. I was told by my mechanic that the OEM plastic/composite Ford oil pans have a chronic problem with leaking seals. Replacing with another OEM pan is highly likely to result in another leak down the road. Replacement at my local dealer is in the range of $3,000.00. Even the service representative admitted that this was a recurring problem with these pans. I note that other TSBs have been issued for this problem. According to several Technical Service Bulletins (TSBs), Ford F150 vehicles, particularly those with 2.7L EcoBoost engines, may experience oil pan leaks due to issues with the RTV sealant on the oil pan gasket, often requiring a replacement of the oil pan itself; this problem is most prevalent in models from 2015-2018, with TSB numbers like 19-2205 and 20-2051 referencing this...

My 2017 F150 is 7 years old with 80K mileage. Engine problem: Cold start ticking/tapping/rattle noise. Ford claimed it sent a letter in 2021 but I never received. Googled and found there are large amount of the same complaints on 2017-2020 F150 with 3.5L EcoBoost engine. The Cam Phaser / VCT Units will fail. Vehicles may not restart after auto-start-stop. Ford issued Customer Satisfaction Program 21N03 and Technical Service Bulletin TSB23-2143. Those measures are not enough. Ford should recall all 2017-2020 F150 with 3.5L Ecoboost built before Nov 30, 2019. Lug nuts at wheels: Ford used cheap two-piece nuts. All the nuts were swollen in Dec 2024 and could not be removed by myself. I had to drive my F150 to Quick Lane and paid $140 to get all the nuts replaced with one-piece nuts. An employee of Quick Lane told me Ford used cheap two-piece nuts for long time,...

I have the Ford F1 50 2017 model, 10 speed transmission. I about it new. In early December 2024 well on a road trip went down shifting the transmission started jerking, feeling like it was having trouble finding the correct gear. This continues to occur with subsequent driving of my vehicle. This was dangerous because it was occurring when trying to accelerate and pass other vehicles with a safe margin. This safety factor was definitely impaired. The speed was not properly controlled and the whole vehicle was jerking strongly. Luckily there were no oncoming vehicles but if there were this could have led to a head-on collision. Hesitancy to properly accelerate is extremely dangerous. Doing some research, I see that this problem was recognized by Ford in 2018 and memos to service departments were put out. I also saw that there is a 6 State class action lawsuit regarding exactly...

My F150 Truck dropped out of gear (5th ) to lower gear while driving. Which is very dangerous and caused almost a potential accident. Seem the power train in transmission and sensors had issue keeping truck in gear. Seems to be an issue on previous F150s and alot of 2017 models

Ford had done a recall on the cam phasers for the ford raptor. The cam phasers were replaced by ford. Now we are having issues with them again just 3 years later and ford will not provide any assistance with repairs which cost around 5000 dollars to fix. We bought this truck 6 months ago. I don’t think it’s fair or possible for there to already be an issue as this part was only replaced 3 years ago.

My truck, a 2017 Ford F-150 3.5L Ecoboost, started making a very loud rattling noise every time I started the engine in the morning. After doing some research online, it became apparent that the issue was due to my VCT (Variable Camshaft Timing). VCT is a FORD DEVELOPED technology that supposedly improves engine performance, fuel efficiency and reduces emissions. I was sold on this technology when I purchased the truck brand new from the dealership back in 2017. I brought my truck into the Ford dealership where I purchased the truck, and was told that this is a KNOWN issue with my particular model. Apparently, Ford is aware of this issue because the Gen 1 trucks (older versions of mine) had the same issue. The problem was supposedly fixed in the Gen 2 versions (my truck), but it turns out that is not true. Ford even has a financial aid...
