NHTSA Complaint #11477939 — 2018 FORD F-150

After starting the vehicle, at any time in under a minute the vehicle's engine will randomly shut off and display a message on the instrument cluster "Auto StartStop, Shift to P then Restart Engine". A photo of this message is included in this report. This issue can occur while in Park, Reverse, Neutral, or Drive. I have had it randomly occur to me upwards of 40 occasions over the past 3 years. A few times I have actually been driving at a slow speed (below 10 mph) when the engine stopped. So far for me, it seems to only happen when the engine RPM's are below 1500 or so. It feels like the engine shakes and then shuts off, then the dash chimes and displays the message mentioned above. I follow the instructions; I turn the ignition off, shift to Park, and restart the engine. Sometimes it starts back up fine and I am able to drive away. Other times the engine shuts off almost instantly and I have to try many, many times (10 to 20) to finally get the engine to stay on so I can drive it. If the engine were to stop while I was making a turn in a busy intersection or on a busy roadway, it would no doubt cause an accident and could be serious or even fatal since I would be unable to move. I have had this looked at by my local Ford Dealer Service shop and they have been unable to replicate the issue. I am not surprised by this since this appears to be random. They have told me to shut off my Auto Start/Stop feature and that is all they did. I have not had this issue looked at by Ford, police, or insurance since thankfully so far it has not occurred in an accident. The only warning message that appears is the "Auto StartStop, Shift to P then Restart Engine" on the cluster. I have not noticed and symptoms that result in this issue so far. This issue first appeared January 2020. Note: This has NOTHING to do with the Auto Start/Stop feature of the vehicle. I have had this issue occur when the Start/Stop feature is active and when it is disengaged.
