Default Mixed feelings

I have had it for a year and a half on a 2016 F-150. I end up disabling it because it’s just unsettling, as others have mentioned, I keep my whole body attuned to how the truck feels, after having had other ****ty cars in the past.

That being said, I could probably be convinced to get over that if not for the timing issues, it needs to give more time before engaging. If I could adjust it from 1 second or immediate shutdown at the stop sign, to engaging after say 5 seconds, I think I’d be good. It just feels horrible when I catch it and it restarts in the middle of a shutdown, there is no way that is good for anything.

True., Thats gotta be odd on a start up as it shutting down. What a PITA

We can also turn this off with our mycal tuning device! You will also get a really nice pickup on power and tq and we also have tow tunes for these vehicles as well!

Default Starter

But think of how many times it starts and stops over the course of a drive. Now what makes this happen...the starter. Ever price one? For my two cents it's permanently deactivated. What little gas it uses at idle outweighs the cost of a starter ever few years.

How about the shortened battery life too?

The MCBF (Mean Cycles Before Failure) of a Motorcraft® Starter is 40,000. I have read that the A.S.S. (Auto Stop/Start) will burden the engine with at least 250,000 starts over three years of city driving.

Ford is most likely only concerned with the reliability of their vehicles within the 5 year/60,000 mile warranty period, I don't know why anyone would trust that reliability would be a top priority for them once it's no longer their problem--use the cheapest materials as possible to meet CAFE standards and ensure reliability for the warranty period.


Seems like a lot of people here trade their trucks every few years, so it isn't really a problem. But for those of us who plan to keep our trucks for around 10 years, I think there is a genuine reason for concern. Plus the AC/heat becomes nearly useless once the engine cycles off. For the past 1.5 years I've just been hitting the button every time I get in, but I'll be disabling with Forscan shortly.
