NHTSA Complaint #11555017 — 2019 FORD F-150

My wife and I purchased the vehicle used from a Ford dealer in 2021. The vehicle was certified used. We had no issues up until the last few months (began in the summer of 2023), but the issue has grown in severity and is random. The vehicle is equipped with an auto start/stop, which we always shut off. Recently the vehicle has been going into idle or shutting off completely and not restarting even with the start/stop disabled. This occurs a majority of the time as we are slowing down to come to a stop, but has occurred while actively driving. This has us concerned we will be in an accident because we never know when the vehicle will just shut off. We took it to a Ford dealer in October 2023 for the issue. We were told there was nothing wrong and no error codes came up. We can provide documentation for this. We finally found online forums and writings where others are dealing with the same issue, but Ford apparently "doesn't know" or can't fix it. We thought we were going crazy! If they can't fix or diagnosis their own car we don't know who will. The most recent date of the issue was 11/13/2023. When the car shuts off an error code pops up stating "Auto StartStop Shift to P Restart Engine". This is accompanied with a check engine light. When we restart it there is no longer an error code or check engine light. This vehicle is not safe! Please help before a tragedy occurs.
