2020 Ford Ranger

While driving my 2020 Ford Ranger, the transmission has repeatedly exhibited unexpected and unintended gear changes, including sudden downshifts or gear changes without driver input, hesitation, and abrupt loss of power during acceleration. These problems have occurred during highway merging, pulling into traffic, and city driving. On 08/14/2026, while accelerating to pull into traffic, the vehicle suddenly lost power, creating a hazardous situation as vehicles approached from behind. I have also experienced instances in which the transmission unexpectedly shifted or hesitated without warning, causing the vehicle to lurch or slow unpredictably in traffic. This condition creates a serious safety hazard because an unexpected loss of power or unintended gear change can prevent the vehicle from accelerating when needed, such as when merging, passing, pulling into traffic, or avoiding a collision. The unpredictable behavior increases the risk of a crash and endangers both the driver and surrounding motorists. The vehicle was taken to Crossroads Ford of Indian Trail on 08/14/2026, where it was diagnosed with a failed or failing 10R80 automatic transmission. At the time, the vehicle had approximately 57,500 miles and was approximately 5 years and 7 months old, which is 7 months beyond the manufacturer's bumper-to-bumper warranty. I have maintained the vehicle according to Ford's recommended service schedule throughout my ownership. I am aware that Ford has issued prior service bulletins and customer satisfaction programs related to 10R80 transmission issues, including TSB 18-2274, 20-2339, 22-2139, 23-2250, and 24-2254, although I have not confirmed whether any of them directly apply to this VIN. I am filing this complaint because the symptoms I experienced—unexpected gear changes, hesitation, lurching, and sudden loss of power—present an immediate safety risk to me, my passengers, and other drivers on the road.

1. Transmission is going out dealership never said a word about the 6 recalls on it one being transmission 2. Front seat belts are in backwards and the child safety hook in back seat has a recall on it that the 3 of the 6 I know of Ford had told alm to replace the entire transmission before they ever sold it they did not do that they didn't take care of any of the recalls

I was traveling south on I-35 going up a long steep hill and my transmission started to hard shift and then I would lose power and when I would accelerate, I had no power it would just stall out so I merged to the right side in case I had to pull over because I thought the engine had died. When I reached my destination, I looked under my truck to discover fluid on the under carriage at that point I knew the transmission had blown a seal or a high-pressure hose. So, I left the truck there and the next day had it towed back to my house. There were times I had slowed down so much that traffic almost hit me.

Coolant intrusion defect that affects other 4 cyl ecoboost Ford engines occurred on this regularly serviced per Ford recommendations vehicle as well. Engine failure at highway speeds could cause a severe accident as the engine can seize when coolant mixes with the oil. The vehicle has been inspected by a Ford dealership. The only warning sign that there was a problem was a coolant temperature threshold exceeded warning.

The truck is currently at a certified ford dealer for diagnosis with a drive train fault. I suspect it is transmission-related, but was not given the history of all stored, pending and history of the codes. The truck exhibits unprovoked forward acceleration/violent lunging when braking to a stop and when driving at low speeds, making intersection control dangerous. It also has severe delayed gear engagement, causing high engine RPM spikes followed by sudden gear slamming, creating a sudden loss of acceleration power while attempting to merge into active highway traffic. The transmission symptoms have been repeatedly reported to and reproduced by certified Ford franchises (Mullinax Ford and Coggin Deland Ford). Technicians previously performed superficial adaptive memory software clears (KAM resets) rather than fixing the physical mechanical defect, which has persisted. The vehicle has been inspected multiple times by factory-trained dealership technicians. The initial symptoms first appeared on May 25, 2023, when the vehicle had 38,575 miles (fully within the factory powertrain warranty window). Persistent symptoms include: 1. Harsh gear engagement/slamming at various speeds. 2. Delayed shifting with sudden RPM spikes before catching gears. 3. Sudden low-speed lurching and acceleration when slowing down. The vehicle has now triggered an active "Drivetrain Fault" warning lamp on the dashboard illumination cluster.

Transmission replacement needed. Truck has been at dealership going on 3 months with continued delays. It was acknowledged cooperate was covering replacement now story changed that owner/myself having to pay $4000+. Cooperate covering $000 . Current owner/myself bought 2 years ago with 13000 miles and has only put 6000 miles on it. Dealership and cooperate admitted to known problem assured coverage however put fixing on hold because they are behind due to staffing issues. I have been bounced around to 3 different people at dealership who have taken case over. Dealership and cooperate blaming each other for lack if communication and delays.

I previously submitted another complaint about a 2020 Ford Ranger I own (tracking number 11707667). I own a 2020 Ford Ranger and had to have the transmission replaced at 86k miles. Since having it replaced, I have experienced all the same problems with the transmission. There have been extremely aggressive shifts, jolts, and lags. It has stalled when going through intersections and more. It has been extremely dangerous. The truck is now back in the shop and the new transmission is undergoing a valve body replacement. The new transmission has less than 15k miles and it is undergoing major repairs as I type this. These Ford 10R80 transmissions are completely and utterly garbage and a total liability to the public. They pose as an extreme safety hazard to everyone on public roads.

Transmission is awful jerky, jumps in and out of gear, causing engine rpm’s to go really high. Shifts erratically, causing me to almost rear end other vehicles. Very dangerous situations a many occasions. Won’t accelerate at times when pulling out in to traffic, causing other drivers to slow down or get in to another lane suddenly. This has happened on many occasions

Truck was shifting weird the day before incident got really bad. The next day on the way home from my newborns dr appointment it began shuddering really badly and would make a loud thud noise when shifting so I had to pull off to the side of the road. There was never a warning lamp or message prior. I took the truck to a reputable transmission shop and they found the issue to be the CDF drum that had shifted out of place. CDF drum and valve body was replaced. Truck had just over 35000 miles at time of repair. I can provide receipt from shop if needed. While speaking to the mechanic at the shop he informed me that this is a common occurrence for these 10 speed transmissions and there was another vehicle there for the same issue
