This vehicle was purchased from toothman and sowers Ford in west Virginia as certified pre owned. It has never run correctly. The transmission has a cdf drum failure which causes it to lurch forward randomly with several near miss accidents. It is completely unsafe to drive. It hangs up on gears and accelerates on its own with no press of the accelerator. Ford says it's $10000 to fix it but they know about it, created a tsb and never recalled. These trucks are a hazard and should not be driven until fixed. I don't drive the truck anymore and definitely won't put my toddler in the truck since it lurched and almost wrecked in an intersection. More near misses in that truck because of this failure than I care to keep track of. Now, it sits. It runs and looks pretty, but transmission is garbage and a hazard.

2 times now my truck went from 75mph in 10 th gear to 1 st gear on the highway. I then loose all throttle input. This is my day driver and some how avoided a fatal crash 2 times. I do not have a ford dealer in my town I usually fix everything on my own. I know they have a recall and it's just a software patch. If so can you push it over the air to fix? Or have a dealer swap out trucks and get it fixed. The trany had been shifting very poorly. I did a filter and oil change on it and was much needed. I also reset the tcm logic and that seamed to help but now I am scared to let anyone drive it.

The vehicle has 57000 miles and i am reporting a commonly known issue with the transmission. Despite multiple service appointments with Ford explaining the issue, I was informed there was nothing wrong. Now, 10 months post extended warranty, Ford is telling me it needs a full transmission replacement. Thoroughout, the vehicle shifted eradically up and down, including on the interstate, quickly dropping speed. It was particularly bad a lower speeds when the engine was cool. Sometimes, at low speed or at a stoplight, the vehicle would disengage the drive train and roll in neutral while the RPMs revved when the throttle was pressed. The vehicle was not operating safely, would roughly bounce around gears, when reported to Ford, told that there was nothing wrong and now being told post warranty that the transmission is a total fail that will require replacement. The latest service appointment one month ago, where I was again told that an oil topoff was all that was needed. This is a well reported safety issue by numerous owners and Ford has failed to take any action or initiate a recall.

while driving at highway speeds the transmission has shited gears causing the truck to hesitate, and stuble hunting for gears. This truck has the same 6r80 transmission that is being recalled in 2015-2017 modles. Please have this modle year include.

I was on Spencer street at the light about to cross on Saint rose park way. When the light turned green my truck wouldn’t let me proceed and the it went into a low gear and make a lot of noise until I crossed and stoped at the Horizon ridge light. At the light I turned off the truck like I have done every time this had happened after ford said they did the recall but after they did the recall I’ve been having all these issues. I turned the vehicle back on and put into into drive and it went into reverse I immediately pressed my brakes knowing there is a car behind me. Thankfully the guy saw the truck with the hazards and going into reverse he immediately went into the next lane. I couldn’t move I was stalled. Had the shut the truck off again and then turn it back on and then I was able to go into drive and sit on the side of the road. Meanwhile I can smell like this burning smell. Now this had happened 2 days after they came out to supposedly fix the recall that was on the truck. I didn’t work the next day after they came out to fit it at my job but driving home that day it drove sort of ok I felt a little lack of going into gear. When I went to work it did a hard jerk while driving like if the transmission was going to fall out. I parked at work for my 10 hour shift and when I went to go home I turned on my truck and out it into drive and it went into reverse. Thankfully I was in park and no cars was behind me. I called ford to tell them what had happened after they came and fix it and they told me it was not part of the recall. But yet when I looked up the recall when my insurance let me know if it people was saying they was having issues going into gears and possibly stalling. This is a serious matter and they keep brushing it off and telling me that I need to pay them to look at it. I don’t feel I need to pay if it is their mistake. I took it to my warranty company and they tried to fix it and found nothing on their end. At this point I gor into almost 5accident

The vehicle skips a beat when shifting and it jumps from 10-8 gear for no reason causing the vehicle to lag or shift rough and break

My truck only has 26000 miles and the transmission started acting very funny, shifting erratically, then it was stuck in 5th gear limp mode. There is some kind of bushing that comes loose in these 10 speed transmissions. It cost me $7597.48. And $150.00 towing.

Manufacturer recall #24E12 (PCM software update) triggered a PO430:00-ED code (Catalyst System Efficiency Below Threshold - Bank 2) because the new software more strictly monitors the catalytic converter, causing it to detect previously ignored degradation. This reprogram scamming program makes community bothered by paying parts replacements more than 2K, even vehicle was fine before the recall. This needs resolved with FREE FIXED and FREE Catalytic Replacement. This is not right to announce a recall with unfinished repair issues left. This needs action. Thanks, So mote it be!

The vehicle’s 10-speed automatic transmission is experiencing severe, erratic, and life-threatening failures at highway speeds. Erratic Shifting & Sudden Downshifts: While traveling at approximately 60 MPH, the transmission unexpectedly downshifts from 10th gear directly to 1st gear without warning. This causes violent deceleration and risks immediate rear-wheel lockup. The vehicle also cycles randomly through gears (e.g., jumping 10-1-7-10-3) and frequently 'locks out' upper gears, making power delivery completely unpredictable. Total Loss of Motive Power: On approximately 3/10/26, while in the high-speed 'fast' lane of the highway, the vehicle experienced a complete loss of motive power. While the engine remained running, the digital gear indicator on the instrument cluster began flashing and the transmission failed to engage any gear. I was left coasting in the flow of traffic and was forced to navigate across multiple lanes to the shoulder without the ability to accelerate. Safety Hazard: These combined issues create an extreme risk of high-speed rear-end collisions and loss of vehicle control. The 'flashing' gear indicator and sudden visible on the dash 10-to-1 downshifts suggest a critical electronic, sensor or software failure that makes the vehicle unsafe for highway operation.
