This data is from the NHTSA — the US gov't agency tasked with vehicle safety. Complaints are spread across multiple & redundant categories, & are not organized by problem.
So how do you find out what problems are occurring? For this NHTSA complaint data, the only way is to read through the comments below. Any duplicates or errors? It's not us.
The Diesel Emission Fluid Injectors are becoming clogged due to crystalized DEF. This causes a DEF error to be generated which de-rates the vehicles speed over time from 50mph to 5 mph over a range of ~50 miles. In remote areas with desert, like where I live this can cause you to be limited to 5 mph on an 80 mph fwy which is incredibly dangerous, especially when some of the more remote fwys are 1-2 lane with limited emergency lanes for nearly 100 miles (especially over bridges). My understanding is this speed limitation is not due to the mechanical operation but is a manufacturer software introduced fault condition, which cannot be bypassed. This also appears to be a wide spread issue as my truck has been sitting in the Ford dealership lot for 2 months waiting for a new injector as these are nationally out of stock. Ford has changed the design on 2023-2024 trucks, the new parts are not forward and backward compatible. Was the design change due to reliability issues with their previous design, should there be a recall for existing customers. P.S. I have a 2021 F350 with less than 15000 miles.
Transmission shifts erratically and sometimes completely doesn-??t work. Has left me in traffic with no ability to negotiate vehicle and was almost hit on multiple occasions. There is a recall on vehicles built before 8-20 Kentucky but my vehicle build date is 11-20. The local dealer said nothing they can do until my 11-20 Kentucky build date truck is included. No offer of loaner and truck is NOT SAFE TO DRIVE !!!!! This has left me without.... transportation..... faith in Ford trucks Also...... same vehicle has the 7.3 ( Godzilla ). Dead miss in 1 cylinder. Internet information says not common but it has happened on multiple occasions. Stuck lifter which causes loss of oil pressure and scoring of cylinder walls. Local Ford dealership said replace 1 head with remanned parts and new pistons. My F350 has 58000 miles one would think it should last longer than that My thoughts. LEMON LAW Thank you for posting of this message. I have spoken personally with several people who have had the same issues and with similar results. Basically nothing from Ford.
The cable connecting the engine block heater caught on fire near the plug. My right hand, thumb and index finger were burned while disconnecting the cable. I was able to stop fire from consuming the vehicle. How ever cable is burned near the 3 pronged connector.
Check engine light comes on almost everyday. After at least 5 minutes driving, this trucks engine will shut down with out notice. Usually when making a turn or coming to a stop light. When this happens you loose all steering control. You have to shift to neutral and try and restart. This has caused me to almost rearend a highway patrol vehicle. Very dangerous. I have had this vehicle in to the local Ford dealership on numerous occasions; however they will NOT run diagnostics to see what is happening. Have ad independant mechanic and my scan tool run tests and it always shows code P0191 fuel pressure rail faault. Maintenance is always uptodate ad fuel filters changed by dealer every 5,000 miles. Dealer and MF not honoring warrenty.
This truck on a daily basis, shuts down with out warning. Check engine light comes on some time, some times get P0191, P0171 and other codes dealing with fuel rail and pressure. Vehicle had less than 10000 miles when started. Dealer don't know what to do. Shuts off when you are in a turn and leaves you with out steering, and shuts off when coming to a stop sign, or trying to park. Fuel filters have been changed 2 times in 2 months. Truck is not safe to drive because it keeps surging and cutting off. Idle speed varies as much as 250 rpm when sitting still. Now
