2017 FORD F-150 Complaints

*What component or system failed or malfunctioned, and is it available for inspection upon request? -The vehicle downshifts suddenly and hard-shifts down on its own. It is worriesome as it randomly happens and oftentimes at high speeds. Yes it is available for immediate inspection. *How was your safety or the safety of others put at risk? -On more than one occasion the vehicle has suddenly downshifted causing a hard noticeable jerk at random speeds. I am worried that at higher speeds it can lockup and cause a serious accident with my kids in the car. *Has the problem been reproduced or confirmed by a dealer or independent service center? -I have taken it to Ford on several occasions in the past but said they didn't notice anything, but I recently took it again and explained the downshift and hard-shift again and now they told me it needs a full transmission replacement that would cost close to $8000 dollars. *Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? -The vehicle has been taken to Ford on multiple occasions but they did not find any issues at first. I took it again as it has happened more often and now they tell me it requires a full transmission replacement. *Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? -The issue first appeared last year, I took it and told them that it had a suttle jerk and asked them to inspect and if there were any recalls. No warning lights. *I am seriously concerned for my safety, it is my only good vehicle and worried it can cause an accident with my kids in the vehicle.

See attached document for complaint. To Whom It May Concern: This letter is submitted as a formal pre-packet notification to the National Highway Traffic Safety Administration (NHTSA). It is not a cover letter and it is not the evidentiary submission itself. Its sole purpose is to formally notify NHTSA that a certified, multi-issue dispute packet has been prepared and is being distributed concurrently to multiple governing, regulatory, and internal oversight entities, and to coordinate assignment of a reviewing party for secure evidentiary transmission. Background and Context This matter concerns a 2017 Ford F-150, purchased and serviced through West Motor Company, Preston, Idaho, and financed through Ford Motor Credit Company LLC. Safety- and recall-related concerns affecting the vehicle have arisen and remain unresolved, directly impacting the condition and value of the collateral securing the associated Ford Credit retail installment loan. Safety / Recall Concerns and Dealer Handling The vehicle has exhibited safety-related powertrain and braking symptoms consistent with known recall or safety campaign issues. Despite written requests for a complete VIN-based recall inspection and completion of all applicable recall work, these matters were not fully resolved. Dealer handling and diversion away from identified safety concerns have impaired both vehicle safety and collateral value. Related Loan Servicing Impact Concurrently, a Ford Credit dispute has been initiated regarding loan servicing practices that materially impaired my ability to access, understand, reconcile, and resolve the account. These practices include customer-portal lockouts during delinquency, forced fee-based payment channels, inconsistent fee assessments, and non-transparent interest application. The combination of unresolved safety issues and servicing barriers undermines any reasonable path to account stabilization. Purpose of This Pre-Packet Notification This correspondence serves to formally notify NHTSA that a multi-issue certified

I was on the freeway in eastern Colorado going 75mph which is the speed limit. Luckily nobody was behind me. My truck went from 6th gear to 1st out of nowhere and I didn't know what to do, very fast deceleration and I almost lost control. I was able to manually shift with the buttons on the gear shifter back up to 6th gear. Recently on the freeway it's been acting awkward and not shifting out of 4th gear.

Repeated Transmission failures. Abrupt shifting that has been repaired numerous times only to return.

The contact owns a 2017 Ford F-150. The contact stated that while driving 55-60 MPH, the transmission unexpectedly downshifted into low gear. The vehicle lost motive power, the brakes locked up, and the transmission failed to shift out of gear. The transmission shifted to neutral and was shifting roughly and erratically. The driver shifted to Manual Mode and was able to continue driving in LIMP Mode. There was smoke coming from the vehicle. No warning light was illuminated. Additionally, the contact linked the failure to NHTSA Action Number: EA26001 (Power Train). The vehicle was taken to the local dealer, who confirmed that there was no warranty coverage for the failure. The contact was informed that the transmission needed to be replaced. The vehicle was not repaired. The manufacturer was contacted and confirmed the warranty status, opened a case, but declined further assistance. The approximate failure mileage was 55,000.

2 years ago i replaced my valve body in my 6r80 transmission due to constant down shifts to first gear at 45 miles an hour and rear wheel lock up with no codes shown. Replacing that part fixed my issue up until today, 2 April 2026, as i was driving to work today and the same thing happened again. Approximately 45 MPH my transmission downshifted to first gear, violently rev'd my engine to 6500 RPMS and locked my rear wheels briefly.

6R80- Unexpected downshifting at highway speeds without driver input causing the vehicle to slow down. Harsh/rough when shifting and sounds like I'm driving on the rudders on the side of the highway. No warning lamps or messages. Occasionally downshifts hard when I'm slowing down and then potentially locking up my rear wheels.

I started my truck this morning and turned on the heat and defrost. Came inside to gather my things for work and when I returned back there was a strong burning smell both inside and outside. I placed my work items in the back seat, closed the door. I heard something falling and found the back windshiled windshield had exploded.

Transmission will jump out of gear. Transmission will shift from 1st to 5th skipping all other gears. Transmission will stay in a high gear even when I’m stopped. transmission will get confused on what gear to be in and jump all around. sometimes the transmission will get stuck in limp mode in fifth gear and I will not be able to move until a loud bang when it shifts back into first. These problems will occur every few weeks and has been going on for more then a year. Sometimes going a month or two without any issues.

Sudden and harsh downshifts happening at speeds above 40mph in normal drivign conditions. The vehicle now shudders while crusing and clunks into and out of gears. The 6R80 transmission now feels like it is slipping when giving the vehicle gas from a standstill.
