   My 2021 Ford F250 super duty pickup truck experienced a catastrophic failure of the Bosch CP4 high pressure fuel pump. This has been confirmed by the dealer's service center. As a result of this part failure, metal shards were introduced into the entire fuel system. This now requires the fuel pump and the entire fuel system (every component) to be replaced. My truck has 74,9xx miles. This is a known and well publicized issue. Rather than recall the high pressure fuel pump, Ford instead issued a recall (24S78) to reflash the PCM software with the intent to reduce the risk of the fuel pump failure. I had the 24S78 recall work completed, and my fuel pump failed still. No indication in advance of this failure.

   Purchased a 2021 F250 brand new from dealership and have had serviced at dealer since new. This truck is equipt with the 10r140 transmission that is a known problem. Starting at 48K miles transmission slipped from 3-5 gear. Report to Mooresville Ford and they “drove” the truck 6 miles and stated they could not recreate the slip. Reported again to Mooresville Ford at ~78k, technician drove vehicle for 12 miles and documented a slight slip between 3-5 but Ford declined to take action and extended warranty to 100k. Reported again at ~96k to Mooresville Ford, dealership held truck for 8 days and drove 6 miles. Declined again to take action and extended warranty to 146k. Reported again to Mooresville Ford at 143k to which they declined action and stated: “without the engine throwing a code they would not cover the truck under warranty.” Had recall 24S78 POWERTRAIN CONTROL MODULE AND TRANSMISSION CONTROL MODULE REPROGRAMMING completed May of 2026 with ~155k. One month after this recall had been completed, a hard down shift from 8-7 and 5-3 started to occur. Reported to Mooresville Ford and they declined to take action and stated Ford would not cover. Down shifting is sudden and harsh and will cause harm to others of truck locks up on road. Someone needs to hold Ford accountable for these bad transmissions. Quote to replace came in at 10k which I am holding out hope a recall comes before I am forced to replace. PLEASE HELP! All service records are on file and can be provided to confirm claims.

   Transmission, temporally could be available but to replace it there is a $1500 core charge The transmission catastrophically failed, which lead to the rear wheels to lock up while driving, putting me and others at risk, had i been going faster when it did lock up No the problem has not been reproduced by a independent service center as i am going to replace the transmission myself I have inspected it along with a mechanic via photos showing all the metal fragments in the fluid and filter No warning lamps prior to the failure, but there where warning lights of service vehicle soon before the transmission locked up. Ever since new the transmission has shifted erratically especially from 3-4 and 6-7. Ford told me this was normal when I brough it in back when it only had a 20 or 30k miles on it for the erratic shifting. I now have 76K miles.

5. Filed Aug 3, 2026Failure Oct 31, 2024Parrish, FLSteering

   While driving the vehicle, the steering column released all of the bearings, allowing for the steering column to move up and down and in and out freely, making it unknown if the steering would follow which way the steering wheel was turned. I reached out to our personal mechanic in regards to this, and had to pay out of pocket. Originally, I thought it was a failed part, but after research, it was brought to my attention of recall 25S94, which my truck did not qualify for. I replace the part at my expense, even though, at this time, the vehicle was only 3 years old. No failure signs appeared.

   This is a follow-up to my original complaint #XXX, filed XXX, regarding the failure of the 10R140 10-speed automatic transmission in my 2021 Ford F-250 Super Duty (VIN: [XXX]). The transmission began exhibiting symptoms of gear slipping, jerking, delayed and harsh shifting, and pinging from the torque converter around 100,000 miles. These symptoms progressively worsened until the transmission suffered a catastrophic internal failure. As documented in the attached Sid Dillon Ford repair order, an authorized Ford dealer found metal contamination in the transmission fluid and confirmed that a complete transmission replacement was required. The attached Friesen Ford repair order also shows that harsh engagements were present and that a transmission flush failed to resolve the issue. I have also attached a sworn statement from [XXX], an independent automotive technician who has serviced vehicles for my family for several years. In his sworn statement, he confirms that these 10R140 transmissions have known serious ongoing issues and that many mechanics avoid working on them due to these problems. Ford Motor Company was provided with the above repair records and the sworn statement but has denied any responsibility or reimbursement for the transmission failure. The failure created a serious safety risk due to the sudden loss of propulsion while driving. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I have up to 16 different codes when the check engine light comes on including numerous communication U-codes indicating faulty software download causing no run/no start problems along with severe safety concerns while driving.

    2021 f250 with the 7.3v8. 120000 miles and lifter has failed. We believe that we caught it early enough to where we have no more issues other than this. After reading up I have noticed where there has been several other customers with same issue on this engine. I run several f350 pickups with our business and have been very pleased and bought this pickup to run around in and keep from driving the work trucks. I would like to think that this should not be an issue with this amount of miles. I hope ford steps up and fixes this issue
