This problem has been ongoing, happening nonstop up to multiple times daily since Feb of 2022 and has spent now 70 days at the dealership in search of the issue. Luckily, the vehicle has not caused an incident yet, but I am afraid to drive it if I get it back from the dealer again as the issue has just gotten worse. The vehicle randomly while driving goes into a "limp mode" in which 1 of 2 things happens. 1) If unable to pull over immediately, the vehicle has very erratic throttle control and 2) the vehicle sometimes gives a warning about the "adavancetrack" system and will sometimes shift itself into neutral out of nowhere forcing you to coast to a stop no matter where or what type of street you are on. In researching this problem to help my dealer at first and now to try and protect myself while in a battle with ford, it seems to be a common problem discussed on many forums on the internet and facebook and seems quite common among the F-150 powerboost. Ford is refusing me a buyback at this time and ignoring the safety implications that my vehicle is having
Complete loss of the throttle while in an intersection. Was able to shut down vehicle, then wait about 30 seconds, then turn it back on clears issue. This has happened at least three times
Both rear axle retaining bolts snapped. The only thing holding the axles in was the brake rotors and calipers.

Both rear axle retaining bolts snapped. The only thing holding the axles in was the brake rotors and calipers. Had they not started squeaking and grinding, I would not have known those critical bolts had broken! At the dealership now being repaired. With the same faulty methods and parts. VERY common problem for the F150 Powerboost with the Max-Tow package.

Rear Axel Bolt Failure. Please help. This has been an issue for over a year with newer F150s. Most failures occur on the "Max Trailer Tow Packages" with the "floating rear axel". You'll see multiple failures on new trucks. Mine has ~18k miles. Dealer says it's unsafe to drive. Many are finding broken bolts incidentally when getting tires rotated. Others like myself hear it rattling. Someone will get hurt. I have a rental car provided by ford because it's deemed unsafe.
Passenger side rear axle bolt failure. The bolt sheared off completely and was found rattling inside the center cap. Dealer states vehicle cannot be driven. Ford will provide rental until repaired but can’t provide estimated repair date.

While traveling at around 70 mph, the truck felt like it losing power. As I further step on the accelerator, the truck didn't response.
