What 1,066 owners told NHTSA about the 2017 Ford F-150 Crew Cab

On [XXX] while driving at 70mph on [XXX] my 2017 F-150 began to shift into multiple gears causing the computer to shut down the trans causing me to coast from the center lane off to the shoulder. the truck shut down. and would not allow me to shift until the computer reset and then allowed me to go home. This happened again on Friday [XXX] leaving me stranded for 20 min in the center turn lane in Berea Ky. I Called the local for dealer who advised they had never seen this issue. I called Ford Customer Care and filed a complaint. on April 7th i took it to Richmond Ky AAMCO Transmission. They advised there is a TSB (technical service Bulletin on the LEAD Frame. The Lead frame houses all the electronic components to the shift solenoid plate. this frame unit is the culprit. and gets dirt between the solenoid electric pigtails causing shorts which causes the trans to freakout. Needless to say it cost me 1600.00 to get this issue fixed. they replaced the lead frame put in a fam spacer that protects the the sominoid connections, the also replaced the solenoid valve plate.

The transmission has been chattering, slipping, and making weird noises since I bought the truck. There are times where the truck will roll forward several feet after I've placed the shifter in park and remove my foot from the brake pedal. In my opinion these issues are definitely dangerous and can get someone seriously injured or fatalities could occur.

Multiple occasions in recent weeks where truck has downshifted rapidly and unexpectedly at cruising highway speeds from 6th gear to 2nd. First incident was on March 8, 2025, while pulling a horse trailer at highway speed of 55mph where truck downshifted from 6th to 2nd causing a sudden slow down of vehicle and risk of crash while pulling trailer. Most recent incident occurred while accelerating as truck was shifting upward through gears it suddenly downshifted to 2nd causing rear wheel lock up. In all incidents the check engine light would come on, pulling off to side of road, turning power off and back on again would reset the truck and check engine light would go away. On April 10, 2025 the truck was taken to the local Ford dealer for a routine service and issues with the transmission downshifting were pointed out and asked to be looked at. The report said there is "TCC slipping actual and TCC desire slipping 100RPMS". The recommend repair was a complete transmission replacement due to high milage. Vehicle currently has 121k miles. I declined repairs at that time due to cost of complete transmission replacement. On April 26, 2025 truck was taken to local SMOG station for routine SMOG inspection for DMV. Truck failed test due to check engine light being on and error code being reported. The error code being reported is "P0720 - Output Speed Sensor Circuit".

Transmission slightly lunges forward after a delay in pushing the gas pedal down - like a throttle surge. The item is not available for inspection. Safety put at risk relative to unexpected slight acceleration. Independent Service Center has verified the problem on 03.25.2025 after I asked for a diagnosis. I was given a TSB 23-2250 for further processing with the local Ford Dealer, since vehicle was under a paid extended warranty. The vehicle is in the shop now for faulty phasers, leaking oil pan, and the subject hesitency and surge of the transmission. The suspected transmission problem has not yet been confirmed by the Ford Dealer Service Center. There were no warning messages or warning lamps indicating I had a problem. The action relative to the acceleration surge just happened. Attachment 1 was the mechanics invoice for making a diagnosis not a repair Attachment 2 was my note to the mechanic specifically outlining items to check for verification Attachment 3 was a TechServiceBulletin he stapled to my invoice informing me that there was a TSB out on the transmission.

Have had issues with transmission for years and was checked previously and dealer said no problems. Seems like it was down shifting for no reason. No recalls. In 2024 while driving I experienced sudden loss of power and seemed like down shifting from transmission on major highway and almost came to a stop in the middle of the lane. This was frightening! This continued to happen. Took to dealer and they said I had to replace the transmission.

On a regular and routine basis, the vehicle is known to have difficulty in shifting between 3rd and 5th gear. Often times, while shifting, the transmission will hesitate to shift before lurching into the next gear. The vehicle is equipped with a 10R80 transmission and has previously encountered issues with the Cam Phasers. Cam Phasers have been replaced, but no work has been performed on the transmission. Driver can replicate the issue on almost every drive.

While driving at highway speed, transmission will downshift into 5th gear mostly, but at times down to 3rd gear. Street driving, it will at times downshift all the way down to 1st gear. Whenever switching from Drive to reverse, it won't go. Have to switch back and forth between the two until it engages. Noticed this issue doesn't happen until the transmission temperature is over 200°.

On March 30th I filed a complaint #11654561. Since that time the vehicle has progressively gotten worse. Traveling at approximately 55 mph the tires suddenly locked up/stopped rolling at normal speed, jerked the truck and I was flung forward. the vehicle would not go over 15 mph AGAIN! Then, on [XXX] I was traveling home approximately 65 mph and truck downshifted and wouldn't move beyond 20 mph. This is getting out of control that I continue to have transmission problems with this vehicle. Talking with a Ford representative he said many problems have been with the transmission conductor plate, there is a defect and having it replaced with any product other than the Ford piece seems to resolve the problem. This is incredible, Ford is telling me what the problem is and won't fix it. How many other people are going through this same problem and we as Ford customers are being scammed of safety repairs. My truck is invaluable to trade in and I'm terrified to drive it. Please, hear my distress and help with a recall to fix our vehicles. Additionally, I just bought this truck approximately 7 months ago. For the 1st 30 days all was OK but as soon as I started traveling at higher speeds this problem appeared. I am afraid for not only my safety but for other drivers if this truck continues to act not safe in traffic.

Vehicle would downshift to 3rd or 1st gear and will not shift out of that gear at any speeds. Would happen at randomly at highway speeds or just from accelerating from a stop, causing dangerous speed changes while on highway. Turning engine/keys completely off and back on will reset the error. Service wrench light would also come on occasionally when this happens. This issue has been prevalent for the last few years since after hitting 60k miles mark. Inspection is available upon request. Issue cannot be reproduced on demand, only randomly. Issue has not been evaluated by any service technicians or dealerships or any other persons except myself using a diagnostics code scanner. Using a diagnostic scanner shows error code "P0722-00 Output Shaft Speed Sensor Circuit No Signal - Not Current DTC."

Transmission will change gears while driving. I can be driving 45 mph in traffic, truck will automatically shift and I'm now going 15 and cannot speed up. There is no warning lites on dash before issue occurs. Called dealership who had no solutions to offer. I cannot be the only one experiencing this issue from reading online forums and Ford needs to be held accountable for faulty equipment. This is a safety issue in traffic for my family.

We purchased this vehicle approximately 6 months ago. On our second long trip of owning it we noticed that when we would give it gas to pass vehicles it would down shift and up shift hard. No warning/error lights came on. We dud have a diagnostic check done but nothing came up. The mechanic at Nicely's said it could be the clutch bank? I read where these similar trucks are having the same issues with shifting and there are some recalls on them. Please help..my warranty was only good for 6 months therefore expired. Where and how to we go from here.

While driving vehicle at 60 mph transmission shifted unexpectedly to a lower gear increasing the rpm’s on engine. Vehicle transmission would not operate normally after this incident.

My truck randomly shifted from 4th to 1st while I was traveling down [XXX] heading south from union city Indiana. Lucky they wasn’t another car near at the time and I was able to keep it on the road avoiding an accident.
