NHTSA Complaint #11681833 — 2024 FORD F-150

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.
