failure of driver side left turbo leaking. Dealership suggests a rebuild of the unit for $3,000 but an independent mechanic suggests the replace the turbo because it has an internal issue that will just cause it to leak again. After researching online this is a common problem with this particular turbo with even a service bulletin. chrome-extension://efaidnbmnnnibpcajpcglclefindmkaj/

Transmission was changing gears with a very noticeable jerk. Transmission would downshift without warning at various speeds. Transmission would not shift into gear when lever moved from forward to reverse - would stay in neutral Fortunately, the vehicle warranty had been extended, and repairs were accomplished under that. But your recent investigation of F-150 years 2015 - 2017 should be extended because similar problems are existing in later years. The repairs to the vehicle cost over $4,700 - all covered by the warranty. And it appears that the problem with the transmission is well known among the mechanics who work at Ford Dealerships
Transmission seems to 'search' for the proper gear, delays in shifting, then violently and abruptly downshifts, with an EXTREMELY loud thud that can be unmistakably felt throughout the whole vehicle, alarming driver and occupants. Even children asked "what just happened"? Passengers believe a universal joint, rear axle, or other key drivetrain component has catastrophically failed. This seems to happen most often when accelerating, letting off of the gas pedal, then pressing the gas pedal again. Vehicle is equipped with a 10 speed automatic. This has been a recurring problem since purchased with approximately 23,000 miles on the vehicle.
My cam phasers are always burning and consuming a lot of oil it also has a ticking sound coming from the engine which Ford says is normal but I don't think it's normal because it gets louder and it happens as I drive all the time. My transmission will automatically slam into a higher gear while trying to accelerate on the highway. Oil is constantly getting into the spark plug chamber even after replacement of seals.
10 speed transmission shifted from 4 to 1 when I was trying to cross and intersection. It has also happened several times when I’m accelerating and hard shifts from the transmission cause my phone to fall and my body to jerk hard causing a ton of distractions in the cab while driving.

Know CDF drum issue starts with hard shifting but now when driving at highway speeds the gear shifter will show it goes from 10th gear to first gear to second gear. Sometimes the engine will actually down shift for a moment. Secondly at low speeds the truck will shift from 3rd to 1st gear causing the truck to lurch forward.
1. Cdf drum issue 2. Transmission will suddenly down shift into 1st when going 60mph and will jerk the truck very hard and it slips when going into 4th gear. 3. Truck was looked at by independent service center 4. No warning light and mechanic said there were no faults on the transmission
The contact owns a 2018 Ford F-150. The contact stated while driving 70 MPH, the vehicle experienced an unexpected transmission downshift. The RPMs increased to 5,000 and then decreased significantly. The contact released the accelerator pedal. The contact stated that the failure occurred temporarily. There was no warning light illuminated. The vehicle was taken to the dealer, where it was diagnosed that the transmission had overheated. The dealer determined that the transmission needed to be replaced. The vehicle was being repaired. The manufacturer was notified of the failure and offered to partially cover the cost of the repair. The failure mileage was approximately 101,000.
The CDF drum bushing in the 10R80 transmission is able to spin and slide inside the housing causing extremely harsh and delayed shifts, momentary neutral, downshift of gears from 7th to 1st gear causing excessive engine reving, shutter shifts in gears 1-6. Ford didn’t redesign the CDF drum until the 2021 model’s, effecting thousands of vehicles with the 10R80 transmission. Does this not meet the safety requirements for a recall?
Rear wheels locked up on highway causing a skid. Vehicle was on fire when came to a stop. Vehicle was towed to a repair shop where the entire rear axle assembly was replaced.
There have been no warning lamps and the issue has been confirmed by my local Ford dealer. I am having a hard shifts slamming down in gear abruptly. In addition between seventh and eighth gear either the computer or transmission doesn’t know which one to be in and the truck begins to shudder sometimes violently. This occurs when attempting to pass at hwy speeds. When you’re next to another vehicle it has led to Multiple near costly incidence. I don’t have confidence passing in this vehicle or towing. The gears slamming down are painful as a passenger.

10r80 transmission not wanting to get out of second or just slamming gears from 10 back to 1 and not driving
Vehicle shifting to lower gears while driving at any speed. Vehicle not engaging into higher gear when accelerating and then slipping out of gear completely. Vehicle remaining in high gears like 7 or 4 when completely stopped.
Catastrophic transmission failure at 44,690 miles.
Transmission slams gears, downshifts hard, takes some time to get into gears if cold. Skips gears (for some reason, not sure if it’s supposed to but it isn’t good for the transmission). Overall, the 10r80 is very jumpy, slams into gear, etc.
The doors do not close when cold i have to use the seatbelt to rap around doors to keep them shut. I have brought to ford multiple times no fix. The transmission erratically shifts through multiple gears and downshifts into low gears when at high rate of speed. Which i have been told is due to a faulty cdf drum in transmission that ford wont take responsibility for. It is a very dangerous vehicle
The transmission on my 2018 Ford F-150 has been experiencing severe and dangerous malfunctions that compromise vehicle safety. Starting around 50,000 miles (currently at 75,000 miles), the truck began exhibiting violent and unpredictable transmission behavior, including: Sudden, uncommanded downshifting from 9th or 10th gear down to 1st or 2nd gear while driving at highway speeds. This causes the engine to redline instantly, the rear wheels to lock momentarily, and the truck to jerk violently, which has forced me to swerve or take evasive action to avoid collisions. Harsh shifting, gear hesitation, and occasional failure to engage gears properly during normal city driving. These issues occur intermittently but frequently, with no warning lights or messages, and the problem persists regardless of driving mode or conditions. I took the truck to a Ford dealership, who dismissed the issue as "normal behavior" for the 10-speed automatic transmission. They quoted a very high fee just to inspect it, with a lead time of several months before they could even look at it. No diagnostic trouble codes were found, and no fix or acknowledgment of the safety risk was offered. After researching the problem online, I found numerous other F-150 owners reporting identical symptoms. This appears to be a systemic failure affecting a wide population of vehicles with the 10-speed transmission. This transmission defect poses a serious safety risk not only to me but to other drivers on the road. Uncommanded downshifting at highway speeds can result in loss of control or a high-speed crash. I believe this issue warrants a formal investigation and recall. The vehicle is available for inspection if needed.
Transmission downshift without warning
The contact owns a 2018 Ford F-150. The contact stated while driving approximately 5-70 MPH, the transmission was shifting hard. There were no warning lights illuminated. On a separate occasion, the transmission was shifted from drive to reverse and shifted very hard. The vehicle was taken to a dealer but not diagnosed, and the dealer was unable to duplicate the failure. The vehicle was not repaired. The local dealer was made aware of the failure. The manufacturer was made aware of the failure. The failure mileage was approximately 22,500.
While driving at highway speeds in my 2018 Ford F150 with 3.5 liter engine and 10-speed transmission when I would need to accelerate to pass or going up a hill the transmission downshift (as expected), but would "jerk" repeatedly until I let up on the accelerator. During light acceleration the transmission still "jerks", but not as bad. No "check engine" light illuminates.
The same problem that is highlighted with the 1.3 million Ford F-150 truck investigation for the 2015 - 2017 models has happened to me. In 2024 my Ford F-150 would switch from 10th to 3rd gear without warning. This has lead to the transmission completely failing. I had to personally replace the transmission myself. I had just went over the warranty mileage. The incident was reported to Ford but nothing was done about it. At the machenic repair shop there were 2 other Ford F-150 that had the same problem.
The contact owns a 2018 Ford F-150. The contact stated while driving 15–20 MPH, the transmission independently downshifted into first gear, the vehicle jerked, and lost automotive power. There were no warning lights illuminated. The contact pulled over onto the shoulder and turned off the vehicle. The vehicle was able to restart; however, the failure recurred. The vehicle was taken to an independent mechanic, where it was diagnosed with transmission failure. The contact was informed that the transmission needed to be replaced. The vehicle was then taken to the dealer, where it was confirmed that the transmission had failed and needed to be replaced. The vehicle was not repaired due to the cost. The vehicle was taken to AAMCO, where the vehicle was repaired. The manufacturer was notified of the failure but declined to provide assistance. The approximate failure mileage was 80,000.
The transmission on our 2018 F-150 with Ecoboost had harsh shifting into 3rd gear and had difficulties with delayed shifting from 6-7, 7-8, and 8-9, with some occurrences of the transmission downshifting to 1st gear. Most noticeable when leaving a stopped intersection or merging on with traffic entering the highway. Cars behind do not expect when our vehicle slows down, resulting in close call accidents. Our truck has been to Ford multiple times and they said this is normal. In February 2025, the truck was returned to a Ford dealership. The service department stated our truck will need the transmission replaced for $11,000. I inquired about this being a known issue. They stated yes but Ford corporate has not acknowledged any issues. I contacted Ford corporate, who acknowledged to assist but then said no due to the mileage being greater than 107,000. The truck was moved to an independent repair facility, and they agreed and provided a cost of $9,500. Currently, I am waiting for the truck to be repaired.
While driving in manual mode on the road vehicle seemingly came out of gear and then slammed into a lower gear causing me to be slammed forward in my seat and nearly wrecked my vehicle, it then unprotected went to 1st then to 9the gear all while still in manual shift mode. Vehicle also dose not always fully engage park when P is illuminated.
