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. 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. This problem happens very frequently but hasn-??t been confirmed or inspected yet. The only warnings are -??Powertrain System fault-?? No systems and first appeared late June of 2024

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 NHTSA 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.

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

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?

The transmission will lurch often, which results in significant engine acceleration hesitation and overall sense of temporary loss of control.
