Automatic Transmission Control Module problems of the 2024 Ford F-150

2024 Ford F-150 platinum powerboost hybrid. Diagnostic codes for power steering loss and can bus communication faults documented at 337 miles, well within the 3-year/36,000-mile new vehicle warranty. The vehicle has been at a Ford dealer since March 10, 2026 for symptoms including the truck randomly turning off while driving and loss of power steering communication. As of this report, the truck has been at the dealer 58 days without resolution. Documented diagnostic findings include: lost communication with pscm (u0131), scp/j1850 communications bus fault (u1028), permanent code p1a42 propulsion system status signal performance, hybrid-specific high voltage system interlock u3523-00, steering position sensor p060a, no communication with power steering control module, intermittent pcm communication during self-tests, bcmc fuse 69 with no power, and circuit cbb69 with no voltage. A Ford field service engineer was dispatched April 23, 2026. On April 24, 2026 the dealer located damaged wiring inside a harness behind the bcmc bracket. Prior to that, the dealer escalated through r&I of multiple modules (pscm, pcm, bcmc, gateway module access) over 45 days without locating the actual cause. The vehicle is currently subject to NHTSA recall 26v104 / Ford 26c10 (trailer module loss of communication at startup) issued 3/18/2026, status recall incomplete. The recall describes the same general failure mode (module communication loss at startup) the customer has been experiencing. Power steering loss while driving is a serious safety concern, particularly given the vehicle's hybrid drivetrain and can-bus-dependent safety systems.

The cause of the accident was due to an extremely hard downshift, then extremely hard upshift. Between the speeds of 25-37 mph the truck will do a hard downshift with a 1-3 second loss of power delay. When it finally grabs gear it takes off like a rocket before grabbing the next gear and back to what feels normal. This is something I never experienced in my 2022 Ford f150 with the same motor and transmission. This particular day, I had pulled off to the side of the road to let the mail carrier go through the narrow section of the road first. This particular section, there is a huge tree right next to the road (approximately 12"-14" off the road). After the mail carrier passed, I started to speed up. Upon hitting 34 mph, the transmission shifted hard, pulled me into the ditch, and by the time the gear grabbed, and I had power to control, I hit the tree. As a habit, since this issue happened numerous times, I looked at the speedometer and just prior to impact I was at 43 mph. The transmission is not the only issue that I have been having with this vehicle. There has been a fuel consumption issue, a hard start issue (does not matter time of day), as well as a grinding issue at the front right wheel. This truck is equipped with a 36-gallon fuel tank. At the city driving mpg and a 34-gallon fill-up, I should have been getting 544 miles/tank. However, that was not the case as I was only getting 440-447 miles/tank (did not matter whether normal, eco, or sport mode driving). Each fill up was a 24-28 gallon fill-up leaving 8-10 gallons unaccounted for. A pcm update was done but it only got me to 510 miles with a 30-gallon fill-up. Each complaint I made with the transmission went ignored with me being told "this is normal for the 10 speeds. You will just need to learn to deal with it. " after the pcm update with no true fix, I was told "drive it to zero mte and calculate from there how far you can drive, then you know. " this is a horrible and extremely unsafe answer to give.
