ESS: The Heart of the Matter

F foreign markets. American Jeep owners shouldn’t have to have this climate nut job crap forced into American rigs.

Nice.

Speaking of F's, what do you think the "F" stands for in FCA?

"On 21 January 2014 Fiat completed the acquisition of the remaining 41.5% from the United Auto Workers, making Chrysler Group a wholly owned subsidiary"

I despise ESS, or any other automated system that makes a car behave differently then I'm used to. I also despise cylinder deactivation, as well (thinking Chevy v8 nonsense here). My last car (2015 BMW 435) also had their flavor of ESS, but thankfully could be disabled, and from that point forward it was disabled and could be re-enabled (god knows why?) by the same button. Of course, I feel that these systems are created for the manufacturers to help them achieve their "fleet" EPA figures.

That said, today I let the ESS button alone, and my brand new 2018 Wrangler JLU Rubicon was able to do whatever it wanted with respect to ESS. Admiditaly with the engine stopped, it fired up right away at a moments notice when the light turned green. At the end of the day, I can live with it, without a complaint. Though I do want to freedom to hit that button to turn it off and leave it off indefinitely until I'm ready to turn it back on again!

Thankfully FCA did not implement any sort of cylinder deactivation. That would have swayed me away for sure.

I personally don’t care for it and just push the button shortly after starting it. Computer is reading 25.2 MPG, I won’t complain about that.

As stated by an environmental regulator higher in the thread, ESS mostly addresses pollution, not greenhouses gases i.e. this, "climate nut job crap" I believe you refer to. If it's so nuts why is virtually every environmental scientist, irrespective of race, religion, political party or citizenship taking this, "climate nut job crap" seriously? Don't you think that even if they might be right, and we're heading down a soon to be irreversible climate change course, that we ought to err on side of caution?

Wait, let me guess, you don't like this ESS because when the average temperature of Iowa, I mean the US (which will be one and the same when the rest of it is underwater) is 122 you'll want to run your Wrangler's A/C full blast at stop lights and not have ESS kick in to reduce its output.

Consider that this "give me liberty or give me death" type talk might be better described as "give me liberty and give me death," in absence of regulations that "we the people" author, that motivate us all to reduce our fossil fuel usage and transition to other energy forms.

I always forgot to press the button so when I stopped off went the ac. That's what irratated me. Driving around town (even topless) I like the ac on low and having the compressor switching on and off at every stop light (which is every 2 minutes in my little town) can not be good for it. Say what you will, but you wont convince me that it's not putting strain on my ac system. So yeah, I pulled the hood sensor, my remote start still works, which I like in the "winter month mornings" which still turn to ac days in the afternoon and I blacked out the idiot light that reminds me it isnt functional. It's a jeep. I get 17mpg and I am happy with that. I'm not looking to conserve gas or my wallet bc I'm a second generation jeep girl on her 8th jeep and I love jeeps for being jeeps, just like I loved my jag & amg for luxury and speed, my mini for the go cart on steroid feel, and my guys raptor for performance. I do think the jeep should have a memory to the button and stay disengaged... that IMO was a thought that should've been followed thru on but hey, I live to tinker on things, my jeep being my fav patient, so pulling the hood sensor was just another 10 seconds of jeep quality time in the sun!!!!

Give ‘em hell girl!

Totally agree... 100%....

I get that people don't like, let alone save much money with ESS. Even under the best of conditions it won't save you much money.

But that's not the sole basis of its existence--not that I'm saying that its haters don't realize that.

Across the entire fleet those gas savings do help.

ESS is but a stop gap measure for automakers to address CAFE standards for fleet MPG that various hybrid and fully electric systems, with things like regenerative breaking will eventually render obsolete.

Ok I have read every post in this thread. Does ESS save gas? Yes it does........the question is for whom? The average person per year we will say high side 10 gallons per year. That is we will say $40-50. That times 10 years. Cool. Now if you take that and spread it over 500,000 jeeps built that is a lot of gas saving. Now my complaint......... ESS is saving us gas but batteries are not lasting 5 years any more with so many discharge/charge cycles we now have that cost burden to us. Engine start up with no oil pressure = wear. Cost burdens past to consumers. HD Starter motor sold at higher cost. Then don’t forget the flywheel/flex-plate added wear. Let’s say we a able to repair most of these things ourself.... just the labor to change the flywheel/flex-plate is around $600-1000 just for labor. My point is the consumer is the one ultimately paying the bill so FCA showed on paper they saved millions of gallons of fuel being disbursed into the air. It is not about saving you any money it is not about saving the planet. It is a numbers game, no more no less. The bureaucracy of the EPA in not about saving the planet or your health, it is about justifying their job. If they (EPA) really cared why in world are we still drinking water poisoned with fluoride. WTF?

It was quite a few months ago that I was able to forget about this feature all together. Sometimes it is the small things

The only time I think about ESS is when I look down and see the light on... don't care about it and not forced to deal with it.

I think the blame should be placed on FCA and other vehicle mfg for not fighting hard enough to allow the consumer to turn it off and keep it off. Putting it in the vehicle is one thing but forcing one to manually turn it off each time the vehicle is started is annoying.

In my old 17' Grand Cherokee the button was directly in front of the gear shift lever so you could hit the button right before you put it in drive but while your hand was still on the shifter. It still had to be turned off but was definitely a bit more convenient.

I was behind a vehicle the other day and he had this feature enabled but it would take a couple of extra seconds for his car to start. So being behind him the light goes green and he doesn't go... I'm saying to myself... go dude! When he was able to finally go he ended up flooring it...lol. Watched this, in his case, gas guzzling scenario happen to him at multiple lights. I guess we will see that same issue more and more as vehicles equipped with this terrific feature start getting older.

Worst part about driving a JL:

You forget to turn off the ESS when starting. You stop at a light and don’t realize it shut off your engine because the music is turned up. You go to take off, drift back on the hill, panic, hear the engine start, curse, and then proceed looking like you don’t know how to operate your vehicle.

 

[CJ7 and 4 wheel drive]

ESS is needless wear and tear on parts. Even heavy duty parts will eventually wear out and I question the necessity of the ESS. I can tell no difference in my gas mileage. I am old school and I just don't care for a piece of questionable, unnecessary technology. It is something to wear out and break in a vehicle that has way too much technology to begin with. When I got my Wrangler JLU, I lifted the hood, took a look see, closed the hood and said to my wife, "I am done with working on engines." There are things under the hood I have no idea what they are or what they do.

 

[Ridgway Jeeper]

Unnecessary complexity. LOT's of owners having battery issues because of this complexity. Funny how the OP keeps gravitating towards a political discussion. At this point we all should realize that HALF of the people agree with you, HALF simply do not and that both sides are 100% convinced they are on the correct side. Bringing it to the Jeep forum is pointless. You will never convince me ESS was necessary for anything other than political reasons, which I find unfortunate. We just push the button as a part of the start up ritual, no complaining, no letters to my representatives or FCA. I still would prefer it wasn't there at all but, it is.

 

[MSteeves]

But what is so difficult about pressing the button to turn it off upon initial engine startup?

Dude.

What you said.

I mean, like ... really.

But then, I got vaxxed, and wore a mask all through the pandemic.

I was wondering about that myself.

I'm pretty sure the 'pollution' includes greenhouse gasses. But then, I would, as I'm one of those 'climate change nutjobs.'

But hey ... what would I know? I believe Doc Fauci, too.
