2020 Ford F-150

The contact owns a 2020 Ford F-150. The contact stated that while driving, the vehicle jerked abnormally, experienced a transmission shifting delay between gears, and occasionally slipped out of gear. The contact stated that after slipping out of gear, the transmission failed to re-engage gear and slipped continuously. The vehicle was inspected by a transmission specialist, who confirmed the failure and determined that the transmission needed to be replaced. The manufacturer was notified of the failure. The failure mileage was unknown.

Transmission slips gears and sometimes shifts violently. I took the truck to a Ford dealership for an assessment and was told I need to replace the whole transmission. I also have a problem with oil consumption from the engine. I was told by the same dealership that this was a known problem with the 5.0 engines built from 2019 to, I believe 2023 and that it would require an engine replacement. I bought this truck from an individual and now I am stuck with it.

The 10R80 transmission failed internally due to the defective CDF clutch drum assembly. Vehicle experienced dangerous gear dropping/slipping. Forced to pay out of pocket at an independent shop for a total rebuild. I have not seen anything from dealer. It was inspected by an independent shop. There was no warning prior to the failure. This happened right over 100,000 miles.

My 2020 Ford F-150 (5.0L V8) experienced a sudden loss of engine power and stalled completely while I was driving. In the days leading up to this, the check engine light had illuminated, and I later discovered the vehicle had consumed a severe amount of engine oil — the dipstick read below the "add" line. Critically, no low oil pressure warning light or audible chime alerted me to the oil loss before the stall occurred. After the initial stall, the engine continued to struggle to maintain idle and stalled repeatedly whenever RPM dropped to approximately 1,000, making the vehicle unsafe to drive. I had the vehicle towed to a Ford dealership for diagnosis. The dealership's estimate confirmed the need for a full engine (long block) replacement, at a cost of approximately $19,824.56 (total estimate $21,491.04). I am aware that Ford issued Technical Service Bulletin 19-2365, which acknowledges that 2018-2020 F-150 trucks with the 5.0L engine may experience excessive oil consumption exceeding one quart per 3,000 miles with no visible external leaks, attributed to oil being drawn into the engine during deceleration fuel shut-off events. I believe this defect directly caused my vehicle's stalling and oil starvation, and that the lack of any dashboard warning prior to the failure is a separate and significant safety concern, since a driver has no way to know the engine is being damaged or that a stall is imminent.

2020 Ford F-150 Raptor supercab with 47,500 miles. Front right coil spring broke into several pieces while sitting in the driveway. Rust on one half of the piece that fell on the driveway indicates rust coating failed and caused the initial break in the coil spring. The way the coil spring broke and the vehicle lost ride height could have killed me if I were underneath changing the oil. If it had broke while driving, it would have caused an accident from loss of control endangering vehicle passengers and others on the road.I will keep all parts and have available for inspection. In hindsight, the only sign this was a problem was noise while driving over speed bumps and it was inspected by several different shops (Ford, VA inspection, two auto body shops) over the last year while it presented the noise. The truck has not been inspected since the coil spring broke.

We purchased a used 2020 F­150 in late summer 2024. We brought it in for issues in November 2024, but the Ford dealership found no repairs were needed. We returned in March 2025 when the CDF drum failed requiring a transmission rebuild, a known issue with Technical Service Bulletin but not a recall. The engine continued consuming oil after this despite Ford completing all applicable service bulletins and advising there was nothing further to do. We took the vehicle in for service in May, 2026 and were told they had already updated software to address the oil consumption and we were told that should resolve the issue. On June 30, 2026, the truck was towed to the dealership after repeated stalling and a check engine light. The dealership again acknowledged this is a known issue with this engine - the valve seals are defective yet they had stalled our concerns so long at this point, we were past the warranty period. We researched and found this was a widespread, known issue asked whether Ford would offer customer loyalty assistance after 30 years of Ford ownership. We were told the truck's approximately 118,000 miles exceeded the assistance threshold. The engine replacement was quoted at $15,000. Ford advised us to repair the engine and save our receipt in case they should issue a recall at some point in the future. Given the value of the truck was $15,000 we chose not to keep investing in this vehicle and sold it for parts at a loss.

Transmission shifted from 4th to 1st while driving a steady 25 mph, then lost all forward drive, the transmission slips, then will slam into gear. I parked it for two weeks until I could get it to the shop. Driving it to the Ford dealer today (2 September 2026) I had to stop the vehicle twice because the transmission was doing the same thing. Currently have 70K miles on it.

I am reporting a safety-related transmission problem I experienced with my 2020 Ford F-150 equipped with the 10R80 automatic transmission. While driving normally, the transmission shifts hard (ie: jerks, clunks) between 4-5 and 5-6 gears, and has on occasion failed to grab 1st gear when starting from a stop (revs, doesn't go). This occurred while turning across traffic, creating a potentially dangerous situation because the truck did not respond as expected when I needed predictable acceleration or propulsion. I believe this incident may be related to the known 10R80 CDF clutch-cylinder/sleeve problem. Ford technical information identifies axial movement of the CDF sleeve that can cause hydraulic-circuit leaks and harsh or delayed engagement and shifting. This condition can result in slipping, RPM flares, delayed engagement, unexpected gear changes, harsh downshifts, lurching, or loss of propulsion. This is a safety concern, not merely a transmission quality or reliability issue. Unexpected loss of propulsion or unpredictable shifting while merging, accelerating into traffic, crossing an intersection, turning, or traveling at highway speed can create a collision hazard. Because I personally experienced this unexpected transmission event, I request that NHTSA investigate the 10R80 CDF clutch-cylinder/sleeve condition in Ford F-150s. Please review Ford warranty claims, dealer repair records, transmission replacements, consumer complaints, and field-failure data to determine whether this is a safety defect requiring a recall. I believe owners should not have to wait for a potentially dangerous transmission failure before this known condition is addressed. Furthermore, I have already had two transmission rebuilds under warranty, and it's going back to the shop for a third time with the same issues 9/8/26. THE SAME ISSUES. I bought this truck in 2024 at 70K miles and it has been nothing but problems.

After starting my 2020 Ford F150 for the last few months on the dash 2 warnings comes up, Front Camera Malfunction Service Required and Pre Collision Assist Not Available. These come on every time I start my truck. I did go to my local Ford dealer and told them these were coming on and they told me they never heard of that. I did have a mechanic do a scan on the truck and he came up with code 4300-49- AF which he said is an internal electronic failure. I have read that people have been having this same issue with their 2020 Ford F150s. I feel this is a safety issue that Ford should address. When system is not working it could lead to accidents which is why this would of been installed on vehicles. I have not had the issue fixed due to the fact the dealer told me they had never heard of this issue and would have to put it on a machine to see if they could even figure out the problem which could run into hundreds of dollars plus repairs and I am on a fixed income. Vehicle is available about any time to check this out.
