2017 FORD F-150 Complaints

Prior to 5/30/25. On 3 or 4 different occasions, I had experienced a very harsh transmission downshift. Most instances occurred under 15 mph from second to first gear. On 1 occasion, transmission downshifted from third gear right to first, at around 30 mph. All of these incidents happened while coming to a stop. On 5/30/25, again while coming to a stop. Transmission downshifted, very harshly. This time the digital speedometer went haywire. Lights flashed everywhere, but no check engine light. Attempting to move forward, transmission shifted randomly and erratically to any gear it desired, both up & down. Vehicle would not go over 18 mph. Vehicle was towed to a local transmission shop. Upon further inspection, they determined that a faulty transmission range sensor was causing these issues. Shop replaced the range sensor, wire harness, transmission filter and fluid. Cost $1155.00. Mileage at that time was 74846. No issues since the repair was completed.

On 2/19/25, I was driving to work. Approximately 2 miles from home I started to hear a grinding / humming noise coming from the front differential, like the 4 wheel drive was engaged. I pulled over and confirmed the 4 wheel drive switch was turned off. I backed up about 20 feet, to disengage the 4 wheel drive. I continued on my way. About 3 miles later the noise returned. I could tell the 4 wheel drive had definitely engaged at around 40 mph. Again, I pulled over. When I got under 10 mph, the 4 wheel drive disengaged by itself. This happened 2 more times within the next 5 miles. Had the truck towed to Ford dealership. Technician could not replicate the condition. They performed a Ford TSB (24-2188) Transfer case control module reprogram. Out of caution, I paid them to replace the 4 wheel drive actuator ($445.00 repair). Mileage on vehicle 74354. Problem seemed to be resolved, until 9/13/25. I was driving on a very busy interstate, approximately 60 mph, I hear a loud thump, like I ran over something on the road. Loud humming and bad vibration coming from front end. No place to pull over safely, reduced speed to 45 mph. As I pull to side of the road at about 5 mph, the 4 wheel drive disengages, vibration & noise goes away. Again this happens 3 times in the next 40 miles. (Mileage on vehicle 75529) No issues since - current mileage 77606.

During the last two years with my 2017 Ford F150 XLT 4X4 5.4L, I've replaced the brake pads 8 times. I've also replaced the rotors on all 4 wheels. Each time, with less than 30,000 miles between needing to replace the pads, the front pads have worn down the entire pad at an unreasonable rate. I do not brake hard, and I drive mostly on highways without much traffic, so having to replace the pads every other month is excessive. With new rotors, still the pads continue wearing down to plate quickly. I've also had to replace the calipers on each wheel more than once because the caliper pins seize and will break when trying to adjust the caliper. The brakes and all the components are a major safety hazard as I'm always worrying if the brakes will function properly any give time I need to slow down. Also, the transmission shifts roughly and even downshifts without cause on occasion. It startles me when I'm driving and suddenly the transmission decides it wants to shift with a violent jolt as though briskly stepping on the brakes. I've had the transmission fluid changed twice in the last 2 years, which did not have any effect on the issue. Prior to each flush, the transmission has also developed a significant leak, which I led to the decision to flush the fluid and replace the pan and gasket. However, after doing so, the transmission continues downshifting and leaking. Once again, these issues have a significant impact on how safe I feel while driving my truck. I love my truck, but I hope my complaint helps Ford fix these little big issues and can develop a fix for future models.

Unexpected down shift with acceleration usually between gear 3 and 4. Shifts hard like ive been hit. Very startling. Doesnt always happen. Usually on hotter days. No warning lamps. No crash occured. Had machanic diagnose and flush and conditioning treatment on the 6r80 transmission and also replaced internal transmission wiring harness that showed signs of over heating at 115k.

I seen there were some issues going around with the 6r80 and wanted to voice my concerns as I am having this issue as well. Intermittently ive been having issues where ill be driving, could be doing 65 down the highway. The wrench light pops up for a second and my truck slams down into 2nd or 3rd gear and goes into limp mode. This could happen at any given time without warning. This just happened to me on Monday, went and got a code reading, and have a code for the output shaft speed sensor. Although I was fine, it is certainly not okay the truck just decided to slam down into gear ultimately slowing down the vehicle tremendously fast while being in traffic. Could have caused an accident or worse.

In July 2024 I purchased a 2017 Ford F150 3.5L Eco Boost pickup truck. Within two weeks of taking possession of the vehicle, the motors oil pump failed which resulted in permanent engine damage. The diagnosis to replace the motor, due to internal engine damage as a result of the oil pump failure, was made by the dealership that sold me the vehicle.

Transmission will downshift and bang very hard. Took to dealer approximate 3 times and was told they couldn't replicate the issue. Warranty expired so I didn't have it rechecked. They did do a computer reset on the transmission.

The contact owns a 2017 Ford F-150. The contact stated that while driving 60 MPH and depressing the accelerator pedal to overtake another vehicle, the vehicle failed to respond as needed, and the transmission remained in 6th gear. There was no warning light illuminated. The contact pulled over to the side of the road. Upon restarting the vehicle, the vehicle operated as intended while driving. The dealer and the manufacturer were not contacted. The vehicle was not diagnosed or repaired. The failure mileage was approximately 180,000.

Check engine light for code for P2007 for an intake manifold runner control valve failure resulting in loss of power. This is well known issue for this era of engines. The runner control valve rod breaks and can not be repaired. The entire intake manifold must be replaced at a cost over $2k.

The contact stated the wrench icon was displayed on the instrument panel. The vehicle was taken to a dealer, where it was diagnosed and determined that the computer needed to be re-flashed. The vehicle was repaired; however, the failure persisted. The vehicle was taken back to the dealer, where it was diagnosed and determined that the computer needed to be re-flashed. The vehicle was repaired; however, the failure persisted. The vehicle was taken to the dealer again, where it was determined that the transmission needed to be replaced. The vehicle was repaired. The manufacturer was notified of the failure. The failure mileage was approximately 54,000.
