I don't think anyone doing this actually considers it a "feature". It should have been made an option that you select one time. Instead they make you turn it off every time you start the truck. Imagine if your truck defaulted to tow mode and you had to hit a button every time you drove it (unless you were pulling a trailer). Would you consider that a "feature".

Not close to the same, but I would not buy a truck if a feature bothered me as this seems to bother some. But I like to save gas. My Fusion Hybrid turns off lots of times.

I don't have the 2.7L so I can't complain. But I wouldn't be afraid to turn the engine off every time I stop. I would just be afraid the damn thing wouldn't restart... then wtf do you do?

The feature don't save me any gas! Truck is not off long enough to make a difference. Not in the town I live in anyway. If I had known the feature was on the truck I would not have bought it and will never own another one as long as I can find one without it. If they would put the button in a more convent place I wouldn't forget the dang thing every time

Lol.

That can (and has been known to) happen to trucks that are already running

I'm with my esteemed colleague Sir Rick. This, to my mind, is what I've always characterized as The Millennial Malady - that societal affliction that causes otherwise sapient folks to display reluctance / inability to apply some simple due-diligence research and patience, and seek solutions that are both elegant and non-invasive. And dare I say - possibly far safer.

Fact is - many of the aberrant 'hacks' folks accept as quick fixes, can be done via software. Invisible. Reversible. Elegant. Safe.

Go look at the Forscan.org list of accessible modules as an example. Sorry, Millennials and their ilk (or worse, their progeny), you'll have to get off yer entitled collective aysses and find that info fer yeseff. Ol' Bubber ain't aboot t' spoonfeed ye lazy butts yet agin

Besides - Ye kin n'er have too many hobbies

Yes a running engine can stall but with the computer telling it to turn on and off, I would think a restart would be more likely to fail when it is constantly turning on and off.

I agree about not buying it if it bothered you. I asked the salesman if it could be turned off and he said "yes", so I bought it. Should have done more research... Adding a jumper to the switch was the best option for me since the alternative is taking a big hit on a trade in.

All I'm saying is not everyone thinks this is a great feature so doing this is a much better than hitting the button every time you start the truck. That got old the first week.

No. Not if the reference design - and the components selected - are sound. And that is indeed the case.

An internal combustion engine is continually being restarted, if you think about it - and then consider all of the myriad components that are in play to keep it so. Adding a couple more is insignificant. IMHO.

Nothing new/old, well-understood and mature tech - and to-date, NO failure mode data to cause anyone any loss of sleep. Probability of getting hit by a chunk of frozen chit from a passing airliner is FAR greater And yes - there was a published study on that.

Ahh... bench racing. It's whut's fer dinner. This is best conducted and savoured over a few

Cheers!

Hopefully it works and has no issues at all. It honestly wouldn't ever save me enough for me justify having the feature. My truck is on the highway majority of the time

So I'm going to skip the toggle switch and wiring.
Any more details on your jumper?
