Does this involve taking a large hammer to ESS button on the dash?I made a discovery which could help others deal with disabling the ESS all together

Could it be that the companies wouldn't be able to report the emissions and MPG gains from ESS if it was just an option that could be turned off permanently?Clearly ESS isn't well received by car enthusiasts so why did FCA make it so it can't remember last user mode in the cars that have it so far? There must be some policy, business, or legal reason for it.
I dunno if that makes sense, when BMW first rolled out ESS in their cars it also reset to ESS ON upon every restart, but they quickly rolled out an update that allowed the car to remember last user mode. By that explanation they would have had their car's MPG ratings revised, but they stayed those figures stayed the same.Could it be that the companies wouldn't be able to report the emissions and MPG gains from ESS if it was just an option that could be turned off permanently?
Yup, CAFE standards, every mpg helps. I agree, it should default to last user setting but we did notice that there is the button for ESS on / off. My Porsche has the same and it starts back up in the button position that was last selected.I dunno if that makes sense, when BMW first rolled out ESS in their cars it also reset to ESS ON upon every restart, but they quickly rolled out an update that allowed the car to remember last user mode.

Good to see you and other Jeep vendors chiming in, it made me turn from lurker to member. I don't really see many companies talking about the JL elsewhere.I am the founder and design engineer at SmartStopStart.com. I make the ESS default memory device mentioned in this thread for the '16-'17 3.6L V6 Jeep WK2 Grand Cherokee, and have a version for the '15-'17 3.2L Standard Cherokee in Beta test, with plans to release it very soon.
I really do not know more than any of you as far as exactly what form ESS will take on the 2018 JL Wrangler. If, however there is a need to better manage this feature, I stand ready to consider a product as soon as the 2018's are being delivered and I can start evaluating one.
I am happy to be here!
Good point. Then there should be no reason that Jeep can't make it so that it remembers an OFF setting.I dunno if that makes sense, when BMW first rolled out ESS in their cars it also reset to ESS ON upon every restart, but they quickly rolled out an update that allowed the car to remember last user mode.

FCA is at the bottom of the domestic list in Corporate Average Fuel Economy (C.A.F.E). This cost them dearly in fines. That is why I doubt they will do what BMW did and offer ESS defaulting to off.

But my point in my last post was that BMW offering ESS defaulting to off didn't change their MPG ratings.FCA is at the bottom of the domestic list in Corporate Average Fuel Economy (C.A.F.E).

My understanding is they offer this if a customer asks for it only as a dealer programmable option and they started doing this in 2012. Eventually they made 'default to last state' standard.But my point in my last post was that BMW offering ESS defaulting to off didn't change their MPG ratings.
No need to worry about that. With ESS both heat and air conditioning continue to work after engine shuts off. The heater core stays hot and the evaporator stays cold after the engine is off and the fan keeps blowing air through the evaporator or heater core. Also, if you have air conditioning on max, ESS doesn't shut off the engine.That and the engine turning off during the summer heat here does not sound appealing.
Fact is the auto makers don't want you to disable it. It just leads to more complaints about poor fuel economy. Eventually ESS is going to be non defeatable, it is just a matter of time so they better get everyone used to it.My understanding is they offer this if a customer asks for it only as a dealer programmable option and they started doing this in 2012.

Five years later I have not heard of any other car-maker offering this.
