Vehicle Information 2021 Ford F-150 PowerBoost VIN: [redacted] Complaint Description While driving approximately 70 mph on a highway, my 2021 Ford F-150 PowerBoost suddenly displayed a "Stop Safely Now" message and immediately lost propulsion. The engine shut down without warning while I was in active traffic. After the shutdown, the vehicle automatically shifted into park and would not allow me to shift into neutral. This left me unable to move the vehicle out of a live traffic lane. I was forced to shut the vehicle off while still in a dangerous roadway position. This incident created a serious safety hazard, as I was traveling at highway speed and could have been rear-ended due to the sudden loss of power and inability to move the vehicle. …

My 2021 Ford F-150 PowerBoost, VIN [redacted], is included in Ford recall 25S75 / NHTSA recall 25V455.

The Ford dealer told me I can bring the truck in, and they will diagnose the problem and repair it if they can. However, I must pay all costs upfront and then request reimbursement after Ford releases the official recall remedy. I should not be required to pay out of pocket for the diagnosis and repair of a known safety defect covered by an active recall. There is also no clear timeline for when a remedy will become available or when I would be reimbursed. I cannot reasonably be expected to pay now and potentially wait years to recover my money. This vehicle repeatedly stalls and creates a serious crash risk. …
