@blwnsmokeAn engine can die at any time for multiple reasons. All I can state from my experience on multiple 2018 Expedition, 2018 Lincoln Navigator and 2018 EcoSport rentals which all had Start/Stop that the vehicle starts as soon as you start to lift off the brake. Unless I slide my foot to the right of the brake and onto the gas, it restarts before I can even get my foot of the brake. The only time I could beat the engine is while pressing the brake as normal and instead of releasing pressure off the pedal, I slid to the right and met the gas pedal (this is not normal in my opinion of anyone).
The starting of the engine takes literally two blinks of an eye unlike a normal start. If your engine is going to die after restart, it would also die if it stayed running caused by the same exact issue.
For those who haven't driven it, here is a video I found. The Start-Stop starts up far quicker then a normal startup when getting into the vehicle. There is next to zero cranking of the engine.
I fully appreciate what you are saying, but must take issue with the fact that the engine re-starts far quicker than a normal start-up. How can that be possible? Think about it.......are the same electromechanical devices in play to start the engine? i.e., the starter cranking the engine? If you were called upon to take an average vehicle with normally-encountered starting system, that is, a starting motor energized by a battery, and make it start instantly, how would you accomplish that? I know you cannot answer that question; and I cannot either.
If the "shut-down" engine were kept in some sort of state where it actually did not shut down, a sort of 'hibernation", still turning and firing it's cylinders more slowly than at idle speed, but not stopped completely, I can see this concept as being acceptable......very quick re-start because it really isn't, and does not involve true "re-starting". I have no idea if this is what they are doing, but I doubt it.
Thus, given the myriad unsafe circumstances as I mentioned, I remain unconvinced. imp
