2017 FORD F-150 Complaints

The contact owns a 2017 Ford F-150. The contact stated that while driving at various speeds, the vehicle momentarily lost motive power while shifting into gear, and the transmission shifted hard. The power train warning light was illuminated, and the vehicle went into LIMP Mode. The warning light was illuminated after each failure. The vehicle was taken to the dealer, where it was diagnosed that the transmission CDF drum had failed. The dealer had not yet provided an estimate for the repair. The vehicle was not yet repaired. The manufacturer was notified of the failure, but no assistance was provided. The failure mileage was approximately 139,000.

Coming down an incline in a parking garage and had a hard down shift while lightly applying the brakes issue is following pre warning signs for safety issues under investigation

Truck sometimes roughly downshifts. I always thought it was normal, but I see that others may be experiencing the same transmission issues. It has happened many times. I only have 77,000 miles.

I live in Canada.While driving, my 2017 Ford F-150 with the 6R80 automatic transmission suddenly shut off without warning. The vehicle lost power while in motion, creating a dangerous situation. The incident was accompanied by multiple powertrain fault codes (5 P-codes). This appears to be related to sudden transmission faults and loss of gear position. No prior warning lights before shutdown.

While driving my 2017 Ford F150, on or about 10/16/2025 the vehicle began jerking significantly. It was intermittent smoothing out then jerking severely again. The problem persisted so I took it to Ford of Spartanburg, SC. They diagnosed a slip found with the torque converter under load. they recommended replacing the torque converter and replacing the transmission filter. I only had 80,006.0 mileage on my truck when this happened.

During acceleration it feels like the transmission is shifting hard and when slowing down something is shifting hard, you can feel it cause you cringe when it bangs into gear. One day my rear tires were skidding driving forward. The shop told me my rear end locked up. I couldn't get a new rear end cause of tarrifs so they rebuilt. Also, there has been squealing coming from under the truck so they capped some vacuum lines but I can still feel a grinding coming through the peddles. They said they did a transmission reprogram but it is still hard shifting during coasting. Thank you for looking into this, I respect ford but I feel the design on this drive train is so poor.

While driving, my 2017 Ford F-150 experienced a sudden loss of the Output Shaft Speed (OSS) sensor signal, causing the transmission to stay stuck in a higher gear and triggering the wrench light. The truck lost power and would not shift properly. A diagnostic scan showed two transmission codes: one for the OSS sensor and a second code indicating an intermittent electrical signal drop. I contacted a Ford dealer before the repair, described the symptoms, and asked for an estimate. The service advisor did not disclose any known issues and never called me back after saying he would check parts availability. These symptoms match the known failure pattern of the molded lead frame in the 6R80 transmission. My truck exhibited intermittent behavior, harsh shifting, and unsafe drivability. I had to pay $1,250 out of pocket to replace the lead frame to restore normal operation. I later learned that NHTSA has opened an Engineering Analysis into 2015–2017 F-150 trucks for this exact issue (OSS signal loss due to internal electrical degradation of the lead frame). My vehicle’s symptoms, diagnostic codes, and required repair are consistent with the defect under investigation. This failure creates a safety hazard because the truck can suddenly lose the ability to accelerate or shift correctly, especially in traffic or at highway speeds. I am requesting that NHTSA include my vehicle in the investigation and that Ford be required to address this defect.

My 2017 Ford F150 has a terrible downshift issue. I am surprised it hasn't dropped the transmission on the road. It has been an issue for several years. It happens a lot when you let off the gas going into a curve, which scares me based on what I am seeing with the ongoing investigation. This needs to be fixed.

Duval Ford in Jacksonville, Florida claims they will not have the part until April of this year which means my child and I are in danger until that time. I will seek a remedy at another dealership but I do not believe it is reasonable to have this part on backorder for 3+ months after a recall notice has been sent out.

I took my 2017 F150 pickup to Aaron Ford in Poway to perform the following: 1) Resolve recall #25V236 Ford Brake Booster 2) Provide an estimate for resolving the "wrench" cockpit display icon Aaron Ford had my vehicle for 3 days they claim, investigating #2 and provided an estimate of $10,000 to rebuild a transmission with <85,000 miles. The recall was NOT investigated nor resolved even though the dealer had the required parts in stock. I would like to file a formal complaint on Aaron Ford's failure to complete the specified recall work as request.
