Open the full vehicle complaint log (all categories)VEHICLE EXTENDED CRANKING WITHOUT STARTING WHILE THE VEHICLE IS PARKED, AND ONCE STARTED IT WAS LOSS OF MOTIVE POWER WHILE DRIVING AND ALMOST WAS IN ACCIDENT BECAUSE OF THIS. SHEEHY FORD SEE ITS A RECALL AND SEE ITS EXACTLY WHAT THE RECALL IS STATING BUT REFUSING TO FIX IT AND WANT TO CHARGE ALMOST 10K TO DO SO.
The transmission began malfunctioning by having hard shifting issues and losing power in some gears. An indicator on the dash lit up resembling a mechanics open-end wrench. Research online showed that the vehicle should not be driven and taken immediately to a mechanic or dealership. If driven especially pulling a heavy load like the fifth wheel that I bought the truck to tow the transmission could fail causing a serious safety issue. I immediately took the vehicle to a certified Ford dealership. At the dealership they informed me that parts in the transmission had failed and that it was the same exact condition as shown in recall 20S33. The noted recall was for trucks manufactured in January and February of 2020. My truck was manufactured March of 2020. The time warranty had expired for the vehicle but the mileage warranty was for 60,000 mi and the truck failed at $29,800. The transmission failed due to a manufacturing defect but I was billed over $9,800 for the repair. I have attached photos of the work order and receipt.
Ford 10R140 Transmission Issues: Transmission has harsh engagement, clunks and slams into gear. Transmission gets stuck in between gears while in motion at all speeds while driving on city streets or on the freeway. Transmission LURCHES forward when shifting from park into drive even when applying the brake and when the parking brake is engaged. This transmission is UNSAFE and UNRELIABLE!!!!
