While traveling on a straight and level interstate freeway with the cruise-control set to 75mph. A huge loss of power followed by a hard downshift from 10th to 7th, up to 9th and attempting to shift back into 10th before I decided to reduce speeds and pull over because it was very dangerous surging/uncontrollable for moments for myself and those driving around me. I noted smoke pouring out from behind the vehicle and that the transmission temp was at 226F. NO WARNING LAMPS/MESSAGES OR OTHER SYSMPTOMS NOTED. Once pulled over, I inspected the underside of the vehicle and noted the whole underside coated in automatic transmission fluid (Red in color). The fluid seemed to trace back to just before the engine/transmission interface. Transmission was serviced 7k miles prior. Dealer advised (through email correspondence) that I let the vehicle/transmission cool down and can then continue to drive the vehicle as the ATF foams up/ expanding and spills out of the transmission vent tube. If problems persist to bring in the vehicle for inspection.

The vehicles transmission randomly malfunctions slamming into and dropping out of gear and slamming back into gear causing vehicle to lose responsiveness. The dealer has informed me its 2018 F150s and Expeditions and they do not have a fix.

While driving down the highway at the speed limit (75 mph), my truck suddenly lost power and partially lost braking. The engine was still running but was running at an idle speed RPM. Both an audible voice and a message on the driver information panel said "drive mode not available, service is needed" Braking power was partially lost at the same time. Steering power seemed normal but braking power was also partially lost at the same time. My truck started slowing down, obviously, and as soon as a shoulder was available, I pulled over onto the shoulder and let my vehicle speed decrease. I only had partial braking power (I estimate less than 30%) so was unable to quickly come to a full stop. As my truck slowed to a speed of about 5 mph, it suddenly started working again, although an icon shaped like a wrench appeared at the bottom center of the driver information panel. At the same time of the issue described above, the air conditioning and air blower fully stopped at the same time, and the multifunction display used for audio and navigation went blank for a moment and reset itself. When it came back on the navigation portion of the screen gave a "GPS faulted" error. I was able to finish driving to work, where I parked the vehicle. Later, after work, and after the vehicle had been parked for several hours, the truck behaved normally, the wrench icon was gone and there was no indication at all that there had been any issue. I was in congested traffic at the time of the event and it could have resulted in a serious highway traffic accident involving multiple vehicles.

Transmission stalls/hesitates when pulling out in traffic. Shifts are irractic.

- Hemingway, SC, USA

The F150 will stall when auto start/stop activates. This is a critical safety issue due to the vehicle becoming inoperable at intersections while stopped. The issue was reviewed several times by the dealership and issue persisted. The issue is still not repaired and mitigated by deactivating the system. This resulted in a lemon law lawsuit from me to ford with me winning a settlement for 8K dollars. However, this dangerous issue must be properly repaired. I am able to demonstrate this issue upon request. I have also have video of the incident with warning lights that activate.

- Hague, VA, USA

I have on numerous occasions had hard upshifts and downshifts and loss of acceleration while traveling uphill or when accelerating in gears 1 through 6. On two occasions I have had vehicles behind me almost collide with my vehicle due to complete loss of acceleration in my vehicle for periods of 4-10 seconds. The problem has been reproduced and confirmed by a Landmark Ford dealership. During these issues the powertrain malfunction indicator light has turned on.

Transmission skipping, banging gears and sometimes separating tires from payment. Reported to Ford the following times: 5/16/2019 at 10,300mi 10/17/2019 at 15,130mi 3/18/2020 at 20,378mi 10/09/20 at 25,596mi 11/22/2021 at 40,330mi Ford has claimed that the banging and hard shifting upward and downward is "normal". They will only conduct a factory reset to the computer to "learn driving patterns" again. This works to resolve the issue, but is short lived.

Whirring sound from right front wheel bearing. Repair shop confirmed I must replace the bearing hub assembly. The parts were unavailable so I was referred to the Ford dealer. The dealer informed me that the repair parts were not available because they were also defective. They also informed me that Ford is showing 16,000 back orders for that part number. They also advised me that the vehicle is safe to drive for now but if the whir becomes very loud it may not be safe to drive. I believe there should be a recall on the involved hub/bearing assemblies.

My 2018 Ford F150 Raptor has major transmission shifting issues. The dealer re-flashed the transmission but issue are still there. I have researched the internet and I see lots of other owners have issues with these 10 speed transmissions.

- Slidell, LA, USA

Initially, gears 1-4 had a very harsh shifting sequence. Vehicle has been inspected by Ford and they calibrated/adjusted the computer program. Vehicle remained the same, shifting hard, especially during a downshift to stop. In the last year, the transmission does NOT engage a gear when accelerating from a stop or coasting while on the freeway during a traffic jamb. This situation is very dangerous when making a left hand turn and trying to accelerate through the intersection and you do not have a gear engaged. Also, there have been instances where the transmission shifts from 1-3 and back down 3-1 multiple times in a matter of seconds and then disengages completely.

2018 - F 150 3.5 twin turbo 10 speed transmission Truck 28K miles: After starting my acceleration from a stop light my transmission just stopped working as if it was not engaged and as I pushed the accelerator nothing was happening. The truck was not moving forward and since I was on a hill the truck started to roll backwards almost contacting the vehicle behind me before pushing the breaks. I was stuck at a busy intersection and had no response out of my truck what felt like 40 seconds before the transmission engaged and the truck to move forward again. This has not happened in the last two weeks but at times it feels like the transmission is grinding when I accelerate from a stop. I plan to bring it into the dealer but need to have my truck and it's been taking the dealers around my area weeks even months to get serviced for repairs. After finding reviews on the web about 10 speed transmissions Ford is using I'm not encouraged by this defect that can be a real safety problem. If a person was walking behind me expecting the truck to go forward and it rolls backward, it could be a fatal mishap. I live in an area with steep hills so Im not feeling very confident in the fixes Ford is doing for other customers who have this same problem as Im starting to experience.

I-??ve been having whistling/rattling in my truck for the last couple of weeks. Tried to make an appointment with my local dealer for the Cam phaser CSP out by Ford for 2018, and other, year models with this issue among other transmission/powertrain issues/problems/defects. I was at a stop light with a red light and waiting for my green left turn arrow. Left turn arrow turned green and I stepped on the gas; my RPMs skyrocketed, stayed in gear 2, and was traveling between 5-10 mph. After roughly 100ft, the transmission switched gears from 2 to 6th gear and the turbos kicked in and I ended up slamming my head in to my steering wheel. This was the last/final straw. The engine has been questionable at best the last couple months and this was the first time I-??ve felt like I am no longer driving the safe, reliable vehicle I thought I had purchase. I have a service appointment scheduled with one of my local dealerships. I hope they fix this issue because if they don-??t/these life endangering transmission/powertrain issues persist I will be hiring a lawyer and fighting for lemon law.

When accelerating to pass another vehicle the truck started shaking violently engine rpms were erratic and I lost almost all forward momentum. This incident almost caused a head on collision. Truck has shifted erratic since purchased and has undergone the lastest ford updates/repairs to no avail. Four-wheel drive is also engaging randomly and has also been repaired to no avail. It would be great if something would be done about these issues before someone gets killed. You just never know how the truck is going to drive on any given day...

Transmission slips gears and loses acceleration. Very dangerous when pulling out onto the road and have had a couple close calls with oncoming vehicles.

- Gonzales, LA, USA

10 speed Transmission has severe jerking and clunking while going through the sequence from 1 to 10 on dash board. It almost sounds like something is bound or about to break. The amount of noise and clunking happens most often. I-??ve been told by the dealer it-??s a normal occurance. My truck has 22,000 and has done it from day one(Nov 2018).

Parked 2018 F-150 on slight incline facing downhill. 12' dump trailer attached with load of 2000 lbs. Put transmission in park and set park brake. While preparing to unload trailer, I think I heard a popping sound. Then the truck suddenly began to roll downhill. It traveled about 70 feet before crashing into two parked cars. I ran to the truck and confirmed the transmission was in park and the brake indicator light was on, confirming that I had set the park brake. The truck had rolled freely with no indication of resistance from the brakes or transmission. Considerable damage was done to my truck, the trailer, and the two parked cars. My truck was towed but repairs have not yet begun and no cause has been determined as to why both the park brake and the transmission failed at the same time.

I have been having issues with my trucks transmission, it is the Ford 10R80 ten speed transmission, It has been slamming into 6th gear so hard that it feels like I'm getting rear ended, I don't even have 50,000 miles on the tuck yet and it's been doing it since it had 29,000 miles on it. My transmission has been to multiple dealerships on six accounts as of today (1-13-22) with an appointment for a seventh time on (1-24-22). The dealerships have acknowledged the problem, and reprogrammed the computer according to their TSB but that did not fix the issue and the TCM computer had been replaced as well. I was told that since the transmission is not giving a code to their scanners, they can not fix the problem. It is potentially a safety hazard because if the transmission finally failes while driving on the main roads or highway, myself and anyone around could be severely injured or killed when the truck loses all power from the trans and stops. This issue has been happening since I purchased the used truck on 6-13-2020 and has never flashed a check engine light or warning. I have seen over many social media outlets that I am not the only one having this issue with the 10R80 transmission, and that there is even a class action lawsuit on that model transmission as well.
