The contact owns a 2017 Ford F-150. The contact stated that while driving approximately 55-60 MPH, the transmission unexpectedly downshifted to first gear, causing the rear wheels to lock up. The check engine warning light was illuminated, and the wrench symbol was displayed on the instrument panel. The vehicle went into LIMP Mode, and the vehicle was slow to respond. The vehicle was turned off for ten minutes and then restarted. While driving approximately 25-30 MPH, the failure recurred. The contact stated that DTC: P1702; indicated an intermittent failure with the transmission range sensor circuit (PRNDL sensor), potentially causing erratic shifting or even the vehicle entering LIMP Mode. The local dealer was contacted, but the vehicle was not diagnosed or repaired. The manufacturer was contacted and opened a case, and referred the contact to the NHTSA Hotline for assistance. The failure mileage was approximately 108,700.

Truck is dropping gears/drop into neutral/reverse/park while driving. Problem initially began only within the instrument cluster, but as time went on it progressed to dropping gears with erratic gear indication on the instrument cluster (flickering through P N D R M 1 2). A video can be provided upon request, but cannot be attached to this inquiry. Once the truck was taken into the shop I was made aware of other F150s of the same year/model having the same issue, and that Ford is currently investigating. The technician at the Ford dealership correlated the issue to the lead frame harnesses part.

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 properly maintained and used primarily for highway driving. It has created a severe financial burden, especially as I transition to self-employment, support a college-bound daughter, and manage transportation as a one-vehicle household. Given numerous reports of similar 3.5L EcoBoost engine failures, I urge the NHTSA to investigate whether this is a systemic issue. Consumers should not face catastrophic engine failures at such low mileage, especially in a vehicle marketed for durability. I appreciate your attention to this matter and look forward to any steps the NHTSA may take. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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 emails, ford is not willing to budge and help their customers with this issue and offer any compensation. Also, I had the oil pan replaced 2 years and 5 months ago due to it leaking. I think this stems from it being made of a plastic compound. Oil gets hot and cold and the weather in Minnesota changing so rapidly causes this to fail so early.

- Carver, MN, USA

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. 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 issue.

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, and it's a common issue on some Ford vehicles. Image if a tire is flat on highway while the nuts are swollen and the flat tire can not be changed! Ford should recall all vehicles using the cheap two-piece nuts. I still keep the old nuts as an evidence.

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 the same issue that has been issued against Ford Motor Company since approximately 2018. The lawsuit shows there have been numerous memos regarding this problem known about the Ford 10 speed transmission and not just in Ford F1 50s. I tried contacting Ford Motor Company and they said "your VIN number was not included in any recalls so you can only complain to the NHTSA". This is a known and dangerous problem that Ford motor company should issue a recall for and be responsible for repairing since it has been known since 2018 while all warrantees were still in force. My warranty is no longer in force, but Ford knew about this during the time of my warranty. I called the dealership at the time that it first occurred and they said that they had been fixing multiple transmission problems and they did get a warning memo at the time that it occurred. However I do not see any warnings on my Ford app. I also saw that in 2002 there was another class action suit against a different Ford transmission problem that was eventually settled in approximately 2008.
