2017 Ford F-150 transmission complaints
Page 8 of 20: complaints 191 to 220 of 560, newest first, as owners wrote them.
My 2017 F-150 had only 87k Miles on it. I don't tow boats or anything heavy. Two months ago my transmission started giving me problems banging when putting in gear and causing my rear end to lock up. Took to Ronnie Thompson Ford dealership in Elijay Ga and they had to replace my rear end. 3500.00 less then 3 weeks later the transmission was not acting right causing shifting and vibration issues. Took to same Dealership in Elijay Ga as I was outta twn again at my second home. They said My transmission was failing and I needed at min a new torque converter. As I could not afford the high price of the Ford Dealership repair I Came back home to South FL and had the Transmission rebuilt for 5500.00 at Gold Coast Transmission in Fort Lauderdale, FL. Ive now Spent over 9K dollars in the last two months to fix this problem. Im a recently retired Ft Lauderdale cop and I cant afford to buy a new vehicle so I've had to put all this money into this prob. Im a Ford guy, my last Ford f150 was a 2000. I put 267k miles on it and had it 18 yrs before I bought this truck. Prior to that I had a 94' Ford Ranger. I put 197k miles on it and before that a 72 Cutlass in HS. Im [XXX] old and have had only 4 cars my whole life. I TAKE CARE OF MY VEHICLES. Of the 4 cars this 2017 is the only new car Ive ever owned and have had more problems with it then any. I see you guys are looking at these transmission and I wanted my complaint documented. If there is a recall I feel Ford should have to reimburse me for the transmission and rear end I just had to replace. Thanks for looking out for the little guy.

I have a 2017 F150 Lariat. When accelerating even in lower gear it may make a harsh noise when shifting sometimes making the truck jerk. Just wanted to report this because I saw a video talking about the problem.
Truck downshifted on its own from 6th gear to first gear. This caused rear wheel lock up around 55 mph. Vehicle became unsafe and difficult to control.
Transmission will randomly downshift while driving or stay in a certain gear without shifting down or up resulting in unexpected power loss. Is sporadic in occurrences sometimes several times in a short drive other times a week without incident
While I am driving in normal drive when my vehicle is in 6th gear cruising there is a shutter in the transmissionthat happens (like running over rumble strips)and only sixth gear. When I have 4 wheel drive locked in the transmission shutter happens in 3-6th gear and only happens at lower cruising rpms and trying to accelerate when I'm either using the pedal or cruise control. When I am in normal driving mode I have to leave 6th gear unselected so the rpms aren't too low to keep the transmission shutter from happening. Brought to the ford dealership and during the ride along with the tech he admitted he could feel it and could be 1 of 3 things the transmission, the torque converter or the torque converter control module. After picking my truck back up they said since I have no codes and they found a flaw in my rim. And that is what is causing the only sixth gear low rpm transmission shutter. And the shutter doesn't happen during higher rpms even at the same speeds. I have read up on this shutter and everyone was saying the same feeling in there f150s and was a transmission shutter. Don't want my transmission locking up at interstate speeds could cause losing control or causing an accident due to lock up
I have taken my 2017 F150 to Sunrise over a period of 3 years to ‘fix’ the downshifting issue on the engine. I was constantly told I was imagining things. Then the dealer kept my truck for 3 months while is was supposedly fixed according to a recall sent out in 2022. The problem was not corrected. Then in 2025 another recall was issued for the braking system and the emergency brake light coming on. Again, back to the dealer for recall repair. And again it was NOT repaired as the light still comes again every time we are driving on the highway. Our truck has very low mileage for 2017. Please advise if you can assist us.

Transmission dropped from high gear to low for no reason. Had fixed at local ford dealer . Happened two times in 2 days.
The contact owns a 2017 Ford F-150. The contact stated that while driving approximately 40 - 45 MPH with the transmission in 4th gear, the transmission unexpectedly downshifted to 1st gear. The contact stopped the vehicle and waited for several minutes before continuing driving. There were no warning lights illuminated. The failure had occurred twice. The contact performed a Keep Alive Memory (KAM) reset after each failure. The dealer was contacted and confirmed that there were no recalls associated with the VIN. The manufacturer was not informed of the failure. The failure mileage was approximately 96,000.
Driving along at normal speed, often on the highway. Truck in 5th or 6th gear. Sometimes 4th. It will shift into 1st gear. Other times it will shift into 3rd or 2nd and get stuck for way too long. I will have to completely stop for it to start shifting "normally"
December 2024 I started experiencing intermittent down shifts from 6th to 3rd. First time was on a very icy road while towing two snowmobiles on a trailer causing it to jack knife and I spun out. Luckily no one else was on the road. After a brief search, I assumed the well know lead frame was the cause. Im a diy person so I ordered new parts and replaced the leadframe myself. I've driven over 10,000 since with no issues.
When driving to visit my family on the road, I was driving normal in 6th gear and vehicle suddenly jump back down to 5th gear at random times and when slowing down vehicle will stay stuck on 3rd gear instead of coming back down to 1st gear. This happened several times, specially on medium, long trips.
while driving at normal speeds in drive mode, the transmission suddenly downshifts to 1st or 2nd gear causing immediate deceleration.
Transmission Valve Body and Lead Frame. With just under 80,000 miles I was traveling on the interstate with my family when the transmission suddenly downshifted, causing the truck to go into a slide at 70mph. Luckily, there were no other vehicles around us and I was able to get the vehicle under control without going off the road or hitting anything. After stopping, checking to see what might have been wrong (no warning lights at the time.), we continued on without incident. A few weeks later, the same thing happened again as I was coming home from work. The check engine light came on and the transmission was locked in 2nd gear. I called a local shop that has Ford certified mechanics and found out this was a common problem, and due to it being a common problem, there was limited parts available to remedy the problem. I ended up having to have the transmission valve body and lead frame replaced as well as the filter and fluid. $1806.35 In both cases, when the transmission downshifted to 2nd, it put me and my family in very dangerous situation. We got lucky! I had everything repaired at my expense and didn't report anything at the time until I saw an article that reported that this had happened to many other people. It is something that Ford should address, and any vehicles that haven't already had this fixed, should be fixed at Ford's expense. Also, what about the people that have had this replaced, such as myself, are we certain the new main frames and valve bodies won't fail in time?
Frequently I will be driving at highway speeds and the truck will unexpectedly downshift. This will happen around every 500 miles. I have only had it drop from 6th to 5th/4th, never any lower at highway speeds. I have had this occur multiple times at slower speeds but it will go away. During each time the code P0720, output speed sensor, will appear and I will have to clear the code and it will work like normal again. There has only been one instance, in my 2 months of ownership, in which the unexpected downshift happened, I then came to a stop and then the truck stalled at a stop light. The truck is available for inspection. My safety and others were put at risk since I lost the ability to control my throttle making my acceleration and deceleration erratic. Also, when I was stalled at the green light it was on a road that had a speed limit of 70 which I could have been hit by another vehicle predicting me to drive away from the stop light when I could not. It hasn't been confirmed by a dealer or independent service center but matches the description of the federal safety agency investigation into the issue. The vehicle component has not be inspected yet. Prior to the issue, no warning lights have popped up. It is only when the issue occurs and I feel the truck unexpectedly downshift and no longer upshift that a yellow wrench will show up with the code i had mentioned previously.
My 2017 ford f150 6r80 transmission lead frame malfunction causing for the transmission to severely down shift and locking my rear wheels. At the time No check engine or wrench symbol showed on my speedometer dashboard until the following day. I was lucky no vehicles were close to me that could of rear ended me and loose control on the freeway. Took my f150 to my local ford dealership and confirmed that it was my transmission lead frame and fixed it.
I just paid 2129.05 to have the separator plate on my 2017 Ford F-150 3.5l /10-speed replaced. The issue was the though bolts in the torque converter were making rotational contact with the stationary separator plate within the bell housing. Ford has a TSB concerning this issue. The number is; SSM52295 ,TSB 19-2230. This specifically cites 2018-2023 models with 3.5l or 5.0l engines, similar issues and symptoms [3.5l/10-speed] occur on 2017 models. It seems this is a known flaw yet there is no financial consideration for this expensive repair. This is not a wear item. It is stationary. This situation has developed over the past several months with most notable audible evidence occurring upon very cold weather initial start-up.
The contact owns a 2017 Ford F-150. The contact stated that while driving at various speeds, the vehicle hesitated while responding and felt like the transmission was shifting in and out of gear. Additionally, the contact stated that the vehicle downshifted unintendedly while driving, and the vehicle jumped and hesitated to respond while attempting to drive from a complete stop. The power train warning light was illuminated. The vehicle was not diagnosed or repaired. The dealer and the manufacturer were not notified of the failure. The failure mileage was approximately 100,000.
While driving my 2017 F150 Lariat 4x4 5.0LV8 with 6speed transmission and 48,700 miles on the odometer at roughly 55mph this morning - the transmission suddenly downshifted to 2nd gear. The downshift was sudden enough to "bark" the rear tires. Thankfully, no one was near me, and I was able to maintain control of the vehicle and reach my destination safely.
The contact owns a 2017 Ford F-150. The contact stated that while driving at an undisclosed speed, the vehicle unexpectedly jerked while driving and attempting to shift gears. There was no warning light illuminated. The vehicle was taken to an independent mechanic, where it was diagnosed, and determined that the catalytic converter and timing components had failed and needed to be replaced. The vehicle was repaired. The contact later stated that while driving at an undisclosed speed, the vehicle lost motive power, and there was no warning light illuminated. The vehicle was towed back to the independent mechanic, where it was diagnosed that the transmission had failed and needed to be replaced. The vehicle was not repaired. The dealer was contacted. The vehicle was not diagnosed or repaired. The manufacturer was made aware of the failure. The approximate failure mileage was 140,000.
The transmission for this vehicle is failing. When accelerating it shifts to a lower gear without warning. It appears to be slipping into gears that it should not be shifting into. When first putting the vehicle into drive it often lurches forward so a hard braking action is required when shifting from park to drive. Dealer is so overwhelmed by transmission issues they require months in advance to see vehicle. Once received they need a week to just evaluate then “up to two months” to repair it. They indicate it’s a known issue with the Ford 10 speeds. A warning notice is constant and cannot be reset. “See manual”
Transmission seems to be faulty. While accelerating the transmission will shift from 4th gear to 1st gear then up to 3rd gear. Sometimes it will return to normal operation at the point, sometimes it will continue to shift up and down at random. I have been told by the shop (more than 1) that the transmission is fine. This random and hard down shifting cause the vehicle to lose speed which is very unsafe. I first noticed the problem about 6 months after I purchased the truck (Oct. of 2024) as a hesitation when shifting from 3rd to 4th. This is an ongoing problem that continues to worsen as time goes on. Currently the vehicle is available with reasonable accommodations to be inspected.
2017 f150 with only 48,330 original miles. Having issues with transmission stalling,jerking in between gears. After last night I have had enough due to an almost potentially fatal accident. While making a left hand turn the transmission stalled for way too long and an 18 wheeler came over the hill ( it’s a blind spot turn) and came very close to hitting me broad side of my truck. This issue could have costed me my life. The transmission fluid is fine as it was checked very recently at my last service less than 100 miles ago. The dealership wants 200 dollars just to hook it up to a computer just to see if the TCM is showing any codes. I have already had that checked for free somewhere else and it is not. The dealership will not do anything unless I pay for that to be done first. I cannot afford to give away 200 dollars for free. But if I give them 200 dollars then they can give me an estimate for repair that ranges from 1000 to 10,000 dollars which is what other customers have paid or been taken advantage of for that amount.
While driving ~70mph on I-80 in central Wyoming, my truck suddenly and unexpectedly downshifted to a low gear, causing RPMs to spike to 8000+ and making me swerve and nearly go off the road. No warning lights or cautions appeared. I pulled over, turned off the ignition, and checked my engine compartment to see if I could find any issues but everything appeared normal. I resumed driving and everything felt normal. Approximately 100 miles later a check engine light appeared. No other cautions or messages appeared. My transmission and engine oil temperature gauges showed readings in the middle of the normal range. I was 10 miles from the nearest town and immediately stopped at a mechanic shop to diagnose the issue. After several days trying to diagnose the issue, they told me that my transmission had severely overheated, was near failure, and needed to be replaced. I had a regular transmission service less than 12 months prior at a Ford dealership and no issues were noted. I am writing this because I am aware of many other F-150 owners experiencing similar problems and I believe Ford needs to address this clearly systemic issue with the 10R80 transmission.
The powertrain/transmission is not receiving the signal from the engine to accelerate. It can be inspected. The vehicle is slow to accelerate or will not accelerate at all, causing lurching motions and slow movement of the vehicle. This can cause my vehicle to rapidly accelerate or me to slowly decelerate, causing me to possibly run into others or be hit by others. No one has reproduced or assessed the problem. The problem occurred multiple times before a warning message was displayed. The signal appeared after two weeks of the failure occuring.
In June 2025 and again in December 2025, when my truck stopped at a Red Traffic Light and I applied my brakes to stop the vehicle, my two rear wheels/tires started to spin rapidly non-stop for 60 seconds or the duration of the traffic light, causing a great deal of smoke and noise. My truck acted like a "Drag Racing" machine on a short track revving its engine and spinning its tires for a very short burst of speed down the track. Cars behind me kept their distance and I thought my truck would bolt forward at any time causing a serious accident. I applied my brakes as firmly as possible, praying my truck would not lose control and bolt forward into the lane of traffic. In June, my mechanic thoroughly inspected my vehicle for four hours, going on a test drive, pulled off all the wheels and checked every pertinent component, ran 3 diagnostic code assessments and found nothing. When it happened again on December 11, 2025, I contacted another mechanic who told me he could not address the issue since it was a known Ford Issue and to contact the federal safety agency and Ford (PE25-002). Finally, there were no warning lights on my dashboard when it happened during these two incidents.
The contact owns a 2017 Ford F-150. The contact stated while driving at 65 MPH, the vehicle unexpectedly downshifted to second or third gear. The contact stated that the vehicle felt like the brake pedal was depressed, and the engine revved to over 5,000 RPMs. There was no warning light illuminated. The contact stated that while driving at slow speeds, the vehicle shuddered, and felt like the vehicle was being driven over rumble strips on the roadway. The contact stated that the unexpected downshifts only occurred while driving approximately 60-70 MPH. The contact was able to reset the transmission by turning off and restarting the vehicle initially; however, the failure reoccurred, and the transmission could no longer be reset to normal functionality. The contact called a local dealer and was advised that the transmission was a closed system, and the transmission case could not be opened. The contact had taken the vehicle to an independent mechanic who diagnosed the vehicle, and the mechanic determined that the valve body needed to be replaced, and that the transmission needed to be rebuilt. The vehicle was repaired. The manufacturer was informed of the failure. The failure mileage was approximately 40,000.
The contact owns a 2017 Ford F-150. The contact stated that while driving at an undisclosed speed, the accelerator pedal was depressed; however, the vehicle failed to accelerate as intended. The power train failure warning light illuminated. The contact stated that the vehicle decelerated from 60 MPH to approximately 40–50 MPH. The contact stated that when the accelerator was depressed, the vehicle failed to respond as needed. In addition, the contact stated that the vehicle jerked and hesitated to accelerate, but eventually started to accelerate. The vehicle was taken to the dealer, where it was diagnosed with a CAM shaft sensor failure. The contact was informed that the CAM shaft sensor needed to be replaced. The vehicle was not repaired. The contact stated that while driving at an undisclosed speed, the contact heard an abnormal sound coming from the vehicle. The vehicle was driven to the shoulder of the road. The vehicle was towed to the dealer, where it was diagnosed with complete differential failure. The contact was informed that the differential needed to be replaced. The vehicle was repaired. The manufacturer was made aware of the failure but provided no assistance. The failure mileage was approximately 90,000.

I purchased a 2017 F150 in March of 25’. Miraculously no issue started until approx 4000 miles after the purchase. The dealer warranty was good for 3500. In the months that preceded issue after issue began to arise. First and least important in my personal opinion. I get in my truck to head to work and my sliding back glass is laying in backseat, completely intact with the track it slides on. One would initially think the GA sun maybe warmed the adhesive to such a Temp that it came loose but my truck is parked in the shade every day at work & at home. Insurance won’t cover it because they say it’s on Ford. Next I have lost power steering, when loosing it i have apparently lost all of steering, uphill downhill assistance an approx 10 other warnings that come every time i crank it. I have been driving the truck 7 months now with no power steering. Lastly and most important, the 10 speed transmission is completely faulty. The problems with it started in July. When accelerating from a stand still, like pulling on the road or highway, over 50% of the time the transmission just fails and you are a sitting duck for any oncoming traffic. Typically 2-4 secs later, the truck will catch of sudden with such a jerk it will give you whiplash. So once you made it through getting on the highway without dying, every shift of the transmission from 4th to 10th, the truck shutters and shakes so bad it seems like it will fall apart. The engine light will start flashing and you can’t go faster than 40-45 for about 15 secs until the engine light is solid again. Then while shuttering you can’t attempt to increase speed. I contacted Ford, I was completely blown off, they denied that 2017 f150 have any transmission issues. I’m forced to drive this daily because I spent all my savings on this truck. Oil change, along with oil filter have been kept up every 5,000 mi. I out everything into this truck and now I have a duct tape back window, no power steering and a transmission faulty.
