2017 Ford F-150 transmission complaints
Page 10 of 20: complaints 251 to 280 of 560, newest first, as owners wrote them.
While driving, my 2017 Ford F-150 with the 6-speed automatic will sometimes suddenly downshift on its own. This causes a hard jerk and a sudden change in speed, which feels unsafe especially at higher speeds. At other times, the truck will not shift into gear at all. For example, when backing out of a driveway or parking spot in reverse and then shifting into drive, the truck stalls. The only way to fix it is to put the truck completely in park, shut it off, and restart it before it will go into gear. This has forced me to be stopped in the middle of the road after backing out, waiting for the truck to restart, which is extremely dangerous when there is oncoming traffic. This has been occurring off and on for a long time now not just one date.
The contact owns a 2017 Ford F-150. The contact received notification of the federal safety agency Campaign Number: 25V236000 (SERVICE BRAKES, HYDRAULIC). However, the part to do the recall repair was not yet available. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The contact stated that while driving 35 MPH, the transmission vibrated and downshifted before slamming into gear. The vehicle was taken to the dealer, where it was diagnosed with transmission failure. The vehicle was repaired, but the failure persisted. The contact stated that four days later, the vehicle was repaired. The contact stated that on a separate occasion, while driving 30 MPH, the vehicle shuddered abnormally and failed to accelerate as intended while depressing the accelerator pedal. The contact stated that the transmission unexpectedly downshifted. No warning lights were illuminated. The vehicle was not repaired after the most recent failure due to the cost. The manufacturer was not notified of the failure. The failure mileage was 115,426.
Cruising on the highway then transmission down shift to 4th gear happened twice
The lead frame failed and was replaced by Ford dealer. The vehicle downshifts while driving. This through a code “wrench” on the dash board indicating something needed to be addressed. Took vehicle to a couple repair shops and a transmission shop and all confirmed it was a faulty lead frame. Transmission shop said to contact Ford because there had been recalls on this very issue for the same year and model truck. This issue started a couple months prior to the repair which was on 8/8/2025. I did call Ford and they gave me a phone number for Auto Line Program. I filed a complaint but it denied.
I was driving my 2017 F150 3.5 eco-boost at highway speeds when I suddenly was in 10th gear and it dropped to first gear locked in my rear tires up while driving 70 miles an hour a manual light appeared in my dash which was the ones wrench. I noticed it would shift down gears on its own when I didn’t slow down, but when I went up and dropped back down to first gear every time. Vehicle is currently in shop. My safety was put at risk when I was driving 70 miles an hour down the highway in my 2017 F150 lariat in my transmission shifted from 10th year down to first locking my rear tires my transmission is a 10R80
While driving down the roadway herd a loud pop loud bang vehicle rear end slid sled to side till I got it under control and pulled over the rear differential cover had a large hole in it metal parts all apart inside the rear end all oil/grease slung out leaving me parked on the roadway till I had the vehicle towed back to my home
The contact owns a 2017 Ford F-150. The contact stated that while driving approximately 45-50 MPH in fifth gear, the transmission unexpectedly downshifted to first gear, causing the vehicle to jerk abnormally. No warning light was illuminated. The transmission then inadvertently upshifted to third and then fifth gear. The vehicle was not diagnosed or repaired by an independent mechanic or the dealer. The manufacturer was not made aware of the failure. The failure mileage was approximately 120,000.
When using the truck in S transmission mode , The back wheels unexpectantly lock up due to a severe downshift. I reported this to the Ford Dealer when it first happened likely around 2018. The dealer kept the truck and reviewed the complaint. They reported that they couldn’t reproduce the downshift so nothing was done. I used the truck in that mode as recent as yesterday. I was going downhill around 20 mph and it downshifted hard once again. It seems to happen when the truck is coasting down an inclined road or when driving say 50 mph and pressure on the gas pedal is slightly reduced.
On July 18, 2025, I was fueling my vehicle at COSTCO. I put my vehicle in park, exited and left the door open while I waited for my credit card to clear so I could start fueling my vehicle. I was out of the vehicle for about a minute when the vehicle started to move backwards. I was standing between the open door and the drivers seat and was startled when it began to move. I was hopping on one foot trying to get back into the vehicle. Ultimately, the open door hit a column at the station. There was damage done to my door. There was no warning that made me aware that the vehicle wasn't still in park and there was an impending issue.
Component: 6r80 transmission lead frame Safety: Driving at 70mph on the interstate on 07/23/2025 and vehicle violently downshifted while in cruise control. Rear tires locked briefly. Driver and passenger were restrained by the seat belts or there would have been a loss of control. I was able to pull to the side of the road. Reproduced: This is the third time in a year that this has happened. Independent shop is scheduled to inspect. DTC codes P061A and P0722 are logged in the PCM. Warning Lamp: After the incident, an amber wrench icon was displayed. Still displayed after restart. Disappeared after 2nd start.
The contact's husband owns a 2017 Ford F-150. The contact stated that while her husband was stopped at a red light, the vehicle shut off with an "Alarm" alert message on the instrument panel. The contact's husband sought assistance and had the vehicle jumpstarted, and the vehicle restarted. The vehicle was taken to an independent mechanic where an oil change was performed, and the battery was tested, and the contact was informed that the battery was in good condition. Upon leaving the mechanic, the vehicle shut off again but another attempt to jumpstart the vehicle failed. The vehicle was towed to a dealer. The vehicle remained with the dealer for four days; however, the dealer could not duplicate the failure. The failure persisted upon return of the vehicle and the vehicle was towed to LaFontaine Ford Grand Rapids (3385 Alpine Ave NW, Grand Rapids, MI 49544); where it remained unrepaired. The manufacturer was notified of the failure and the contact was referred to the federal safety agency Hotline to report the failure. The failure mileage was 74,800.
While driving with my cruise control at 75, the instrument cluster began to blink on and off like it was shorting out. Then the truck would suddenly downshift and search for a gear. It continued to do this until I could exit the highway. The truck aggressively downshifted multiple times quickly decelerating the vehicle. It was pretty scary.
My 2017 Ford F-150 is experiencing an oil pan leak. F150 model is equipped with the 2.7L EcoBoost engine. This is a lack of RTV adhesion at the oil pan seal. My dealership wants over 1k to fix which I refuse to pay. This issue was created by poor engineering and craftsmanship on Fords end and the consumer should not have to pay to fix this known issue. I understand there is a fix that involves a 1-piece aluminum pan, as seen on many you tube videos. I'm requesting that Ford be held responsible for fixing this issue and not the consumer, who paid a lot of money for this truck. Any help in getting this resolved would be greatly appreciated.
Vehicle transmission will instantly drop to gears 3 to 5 (limp mode from what I have researched) & wrench light comes on. Very dangerous on the interstate traveling at 70mph+, seems to happen more frequently on hotter days. You can park & turn off vehicle, then crank back up, & it is out of limp mode but transmission is sluggish. Initially it was happening once per week on avg, now it is a toss up on each drive I do whether it goes into limp mode or not.
Transmission started jumping hard from park to drive , progressed dropping from higher gear to lower gears hard while driving causing the truck to lock up and skid does it at both higher speeds and lower speeds even while idling down the road .
There is an engine rattle when starting the vehicle. I took my vehicle to Ford of Upland dealership. They said I need to replace my VCT Solenoids and water pump. This was a known issue for this year and make of vehicle and I never received any notification. Now, they want to change me $6000 to repair it. There was TECHNICAL SERVICE BULLETIN 23-2143 issued for this defect.
When the vehicle is started, the cam phasers rattle, and yes, it is available for inspection upon request. Ford mechanics and other mechanics have stated that if not replaced, the cam phasers will eventually fail. This puts others at risk as the auto start/stop feature shuts the engine off anytime the vehicle comes to a stop. If the cam phasers failed while stopped in the road, the vehicle would not start back up, causing a rear end collision and possible injury/death to anyone on the road. The problem exists in the 2015-2018 Ford F150 3.5L ecoboost. Ford resolved the issue in the 2019 model F150 by replacing the cam phasers with ones that are built with better quality. I am unsure if the vehicle issue has been inspected by others. There have been no warning lamps, messages, or other symptoms of the problem prior to the failure. It first appeared in my vehicle around this year.
This incident has occured twice. The first time, February 2025, I was driving the vehicle at approximately 55mph with Cruise Control engaged. The vehicle took itself off cruise and drop shifted to 1st gear. The rear tires skidded but I was able to pull over safely. Wrench warning on the screen. I shut off the vehicle. Restarted and the wrench icon was still present and vehicle would not shift to higher gears. Restarted again and the issue was gone. Independent service center could not find any issues or reproduce the problem. The second instance, July 1st 2025, occurred while towing a travel trailer. I was traveling at 25mph and the truck shifted to 1st and the rear tires locked briefly. The wrench icon appeared on the dash and then disappeared. It happened again just a minute or so later and then did not reoccur. Due to the low speed, no injuries occurred and control was maintained. I am certain that if this had happened at highway speed, there would have been an accident.
My truck is going me a P0720 code which tells me that my Shaft Output Sensor is bad. It is built into my lead frame. This is a known issue with F150’s I have seen. My transmission is clunky and downshifting randomly.
Truck rapidly shifted from fifth to third gear, causing the truck to jolt and lock the rear tires. This has occurred at least three times since a recall was performed on the truck’s computer several months ago. After it happened today, the truck produced the following codes: P0720 and U0102. This could be detrimental when driving at high speeds on the highway. Truck can be inspected if requested. A local Ford dealer has been informed about the issue and stated that the recall would not have caused it. No inspections have been performed due to the inconsistent occurrence of this issue.
The contact called on behalf of his grandson who owns a 2017 Ford F150. The contact stated that while his grandson was driving at slower speeds, the vehicle shuddered abnormally. No warning light was illuminated. The vehicle was taken to a local independent mechanic where it was diagnosed and determined that the torque converter had failed. The contact was advised to take the vehicle to a local dealer for assistance or a transmission specialty center. The vehicle was not repaired due to the cost. The manufacturer was notified of the failure and referred contact to the federal safety agency Hotline for assistance. The failure mileage was approximately 175,000.
While traveling at highway speeds, my truck will downshift from 6th gear to first gear. On occasion, the heads up display will randomly flash between different driving modes (reverse, M, Neutral) as if it is resetting. This also happens at medium speeds (20-30 mph)

Driving in a 45 mph sped zone transmission went from high gear to second..would not up shift or down shift… Because the truck was traveling 45 and then slowed others had to go around. The wrench light came on about the same time the transmission locked The dealer rep said that there were problems with this transmission and would be better with a replacement transmission.. 77032 miles on truck
Consistent hard shifting and hard downshifts.. Dealership charged us to reset this and it has not solved the problem I bought this vehicle used at 77,000 miles and it was the biggest mistake I ever made. Ford keeps denying that there’s an issue with the transmissions and I’m genuinely afraid to own this vehicle.
I was driving at 62 MPH and the truck suddenly down shifted. It is a 6 speed transmission and I was in 6th gear when it down shifted. The indicator that displays what gear it is in disappeared but the rpm went form 1,500 up to 3,000 very abruptly. In fact, when it happened, the back wheels actually hoped up and down a couple of times. I tried to shift in manually but nothing. I stopped the car, restarted and it would not upshift. I put the car into neutral while I was rolling and then put it back into gear and the transmission stared to act normal.
The intake manifold on this series of trucks is a commonly found failure. It is costly as it requires complete disassembly and reinstall for internal components, that lead to poor performance and eventual engine damage if not repaired. I had a SES code 2019 flag for this and required me to have >$1500 repair to resolve by a reinstall of a new intake manifold by the Ford Dealer on May 21, 2025. This should have been recalled with the vast number of problems seen online and that the dealer had this part in stock as it is so common. I was only 50d after my extended ESP warranty when it went.
10r80 transmission has completely failed making the truck undriveable
