While driving 80 mph using cruise control on flat straight freeway, vehicle randomly would downshift from 10th gear into much lower gears, causing rapid deceleration. This happened multiple times, after transmission issues were reported to dealer and dealer "could not find any issues." Dealer eventually said new transmission was needed, replaced it, and then 30k miles later similar transmission issues are happening.
2017 Ford F-150 transmission complaints
Page 14 of 20: complaints 371 to 400 of 560, newest first, as owners wrote them.
During a 5,000 mile vacation trip thru mountainous terrain the transmission wouldn't downshift properly and has continued since during everyday driving. There is vibration felt through the truck and steering wheel. I made an appointment at the Hanover Pa dealership and they verified the problem. The Ford garage had it 4 days and put in an entire rear drive shaft which didn't fix it. The next trip there, they replaced the torque converter which they immediately told me still didn't fix it and it's been there a week torn apart. They have now replaced almost $4,000 worth of apparently functional parts. Our last conversation was they don't know what is wrong and they need to contact Ford. The first hazard l face is the truck won't shift down in a timely manner, especially on hills to come to a full stop. The next hazard is the truck sitting at the Hanover Ford dealership, torn apart for yet another week and they aren't equipped with an answer.

The local dealer and manufacturer were notified of the failure but no assistance was offered. The failure mileage was 120,000.
While driving down the interstate the truck randomly started shifting into all the gears randomly which was making the rear tires seem to lock up. The dash instrument panel had the gears randomly cycling through them also.
On 8/19/24 the transmission started slipping mildly. 8/20/24 slipping progresses to total failure to engage. I was on the highway (10 miles out of town) when it became clear I would not make it to my destination- I pulled off at a driveway to turn around and attempt to make it to my mechanic. At the driveway, I placed the gearshift in reverse to make a 3 point turn; the gear would not engage and the truck rolled back into a ditch, with 1 tire suspended in the air, tetering at a wavering 45 degree angle. Leaning weight of all passengers uphill and placing truck in 4-high, the transmission did engage in drive and I was fortunately able to avert the seemingly inevitable rolling of the vehicle, and we were able to pull out onto the road. Terrifying. We made it to my mechanic, who ran codes and got: PO 772-00 and P2704-00. He sent me to the transmission shop, who told me they will not touch a Ford 10 spd tranny because they have so many problems. The Ford dealer has advised it needs a new transmission tot he tone of $10k. They encouraged contacting Ford Corporate. Ford Corporate informed me that yes, the 10 spd transmission do have a lot of known problems, and there are a number of recalls, based on date of manufacture and batch manufactured at specific plants. Though my truck is exhibiting the same catastrophic failure of the transmission as those recalled, Ford informed me my batch is not included in the recall and thus they will do absolutely nothing to help me and the pay will be my responsibility out of pocket. My case # with Ford corporate is CXH02611974.
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.

Ive had a few incidents where the vehicle shifted so hard into a lower gear that the tires made a sound. I thought the truck was going to break. I can have some one behind and I would be rear ended. My truck will get in a wreck just a matter of time. Especially if there is a turn, rain, snow, ice, a hill, or someone behind me. Other incidents with the powertrain have happened like not wanting to shift and the lights start blinking. The truck doesn't know what to do. So if this happens at a stop light, a stop sign, parking lot on the highway, I will probably get in a wreck. I've had it checked by a couple mechanics and they don't know. Its all over the forums of people having issues but nobody has a solution. And if there is a solution its very expensive. And not really sure if that fixes the issue. Its a very unsafe vehicle and only a matter of time before Ford gets sued for millions. I've already made a claim with Ford. They have refused to help me in the situation.

My transmission will down shift into 2 gear no matter how fast I'm driving and my gear position on the dash goes out but no check engine like has come on yet this has happened multiple times in the pass couple weeks. The last time I was driving at 65 MPH and the truck down shifted and locked the back tires up and motor RPM hit 8000. The truck slid about 200 yards before it slowed down and started shifting back into 6th gear. I was pushed up into the steering wheel if my seat belt would have stopped me I could have hit the windshield. I refuse to drive this truck until it is fixed and can be proven it will not happen again. Thanks for looking into this...
Truck makes loud clanking noises while shifting. Has very hard shifts between gears upon acceleration and braking. Holds transmission in certain gear till the truck almost redlines before it very aggressively shifts. Makes a grinding type sound when accelerating at low rpm.

I am writing to formally submit a complaint regarding persistent and significant issues with the cam phasers in my 2017 Ford F-150 EcoBoost. I purchased the vehicle in December 2019 with 40,000 miles on it. Since then, I have experienced ongoing cam phaser problems, which have led to considerable inconvenience and expense. In February 2022, with 92,000 miles on the vehicle, I took it to a dealership for reprogramming as per Ford’s Customer Satisfaction Program (CSP). Unfortunately, this did not resolve the issue. The cam phaser problems persisted, ultimately resulting in a major repair on June 17, 2024, when the truck had 134,000 miles, costing $4,100. 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 federal safety agency 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.
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.
2017 Ford F150 5.0 w/6speed transmission experienced the following: While stopped at the redlight with brakes applied, my vehicle lunged forward as if hit from behind. After the light turned green, I accelerating, my truck throws up a message on dashboard with the orange wrench saying See Manual while at the same time, the transmission downshifted to 2nd gear for a few seconds then accelerated normally. After about 30 seconds, the message disappeared. No check engine light yet. Two evenings later, my truck downshifted to 2nd gear again for 2-3 seconds while driving at 60 mph then upshifted to 6th gear, the gear indicator (P R N D M 1 2) started to show that I was not in any gear then showed then I was in neutral. This neutral indication lasted until I got home 5 mins later.
In multiple cases the transmission will shift from its current gear down to first. The incident has happened at various speeds and various gears.
The contact owns a 2017 Ford F-150. The contact stated that on several occasions while driving at various speeds and while in reverse, the vehicle jerked abnormally. The power train warning light was illuminated on several occasions. The vehicle was taken to a dealer; however, the failure was not able to be replicated. The vehicle was not yet repaired. The manufacturer was notified of the failure. The failure mileage was 72,300.
I was driving at 65mph on the freeway when suddenly the gear selection starts to blink and the truck went from 65mph on 6th gear to 2nd gear. The truck would not shift to 3rd gear, the service light came up and the wrench light. The codes that came up at P0706 and P0707. I noticed via forums and YouTube that this is a problem multiple drivers have been experiencing. To fix this issue is from $800 to 3,500 due to the Frame lead going out.
While driving the truck will suddenly shift down, lose power and transmission will shift from 10 to 1 very fast causing near accidents many times. I have had it in a repair shop and have been told it is a faulty transmission. This happens every time we are on a road where speed is over 50

I have a 2017 F150 that has this exact same down shifting issue mentioned in the following recall. “Ford Motor Company (Ford) Recall No. 24S37 Chronology CERTAIN 2014 FORD F-150 VEHICLES EQUIPPED WITH 6-SPEED AUTOMATIC TRANSMISSIONS – UNEXPECTED TRANSMISSION DOWNSHIFT.” This issue has happened to me several times at various speed. The issue started occurring several months ago. There is no way to predict when the issue will occur, it’s completely random. I have taken it to an independent mechanic who was not able to reproduce the issue or diagnose the problem. There were no codes stored in the scanner tool they use. I have not taken it to Ford since there is no way they can reproduce the issue. I have reported it to Ford, case CXH-02297813-T0J8Q0 There was a recall previously for the same issue for 2011-2013 years and has now since been expanded to include 2014. The Ford reference number for the previous recall is 19S07. My 2017 F150 has the same transmission and it seems like more than a coincidence that I have experienced the exact same issue and have the same transmission. I believe that Ford needs to investigate all year models that have the same transmission and expand their recall to include them. I’m assuming the only included 2014 recently because they got complaints from owners?
