Whats is your opinion the jeeps engine stop start system?

[Jaxmax]

I don’t like it, turning engine off with oil draining down , oil pressure dropping , just bothers me more then the gas savings and I am really annoyed that the button does not retain your prior setting. Letting me turn off and leave it off would make me feel better, but not good enough to change my opinion….Jack

I don't even notice it, it's been common on most cars for a while now, it's almost weird when they don't shut off.

Have you watched what happens to the oil pressure on a restart? Yeah - the engine never even knows it. Warm ESS starts mean the pump is in high volume mode instantly and the pressure hits 70+ as it first fires.
Not sure what is meant by oil draining down.........

The real issues is all of the false beliefs, bad information and people who find something "annoying".
Engines have been stopping and starting since the advent of the hybrid. Hmmmmm

But here we are again, 5 years later, the same old things over and over and over, and half of it incorrect.

Part I - It sucked at stop signs. The engine would shut off just before my turn to go, meaning I cannot wait 3" for oil to get to the heads again before getting on the gas.

Part II - A better question might be who would have chosen ESS/ASS as a $500 option; who would pay extra to get it?

Part III - There was a reason that the sales guy pointed out the avengers button during the test ride.

LOL That's funny. Love all of the hate over something people have gotten so very wrong, assuming, and taking "the internet" BS as fact.
People who know nothing of engines keep spouting that sort of thing - oil PRESSURE doesn't protect the followers and cam lobes. In fact, it's the oil film.
If you are that concerned, never ever shut your engine off! All of that oil drains down,, things dry up and you'll ruin the engine!

Man, people wonder why I take breaks - all of the crap, so few facts.
People who have no real engine experiences telling everyone else all about it.

Love it! Keep it coming. I'm really amused at the total lack of understanding.

I think the laws changed in 2016 or so. But before then, ESS buttons did retain their prior setting at the next start cycle. I own a 2015 Porsche with ESS. I pushed that ESS Off button once, on delivery day, and its stayed off for over 10 year now.

As I recall from my research over the years, the system was invented by BMW - for Europe.
As far as the dual battery setup - BMW, Mercedes, Ford and even Chevy used it, among others.
Yeah, there's a lot of info out here - probably several polls already, dozens of threads, some years old and 100 pages long I bet.
But people will keep on about how evil and useless it is and keep parroting the same old stuff, disproven years ago, or whatever cousin bubba said.
I'll sit and laugh and enjoy the show of the armchair experts telling how evil and destructive it is. (something around for over a decade, and forgetting about the many hundreds of times a hybrid gas engine restarts each trip)

Amusing.

(BTW - where's the chemtrails thread?)

i have absolutely stalled out because the ESS system shut the engine off right as i was ready to engage the clutch and because it just shut itself off it wasn't immediately ready to restart.

Twice was enough for me to turn it off every time i start my truck. With my previous automatic gladiator it was fine.

That's why I ask at times "manual or automatic".
It's a different animal with a stick, I can see that.
With my ADHD, when my wife isn't with me, I'm one of the first ones away from the light when it hits green. I guess all of those times watching the tree......... and hating to be behind anyone, get the heck out of my way sort of a thing. I also find that when 2 lanes on a ramp suddenly turn to one that people in cars tend to assume a grey-haired old fart with 25 extra pounds driving a Jeep truck isn't going to be taking off any time soon after the light changes. I swear - I'm going before the green lamp in that signal even gets warm.
Like you said - the automatic it's pretty near instant. Call me a "competitive driver" - I have to admit that it's how I'm wired. So if something even ever-so-slightly interfered with my being the very first one away from that light - I'd be pretty upset. It would be done.
I also know how to manipulate the pedal to cause it to not shut down if it's a stale red.
(I had to add limited slip and Caltrac bars to my 73 Javelin due to my - well, quick take-offs from a light. My wife was constantly after me with my 70 until I rebuilt the torque links and adjusted them to prevent rear wheel spin. So anything that meant I was not a perfect 0.0 reaction time would be gone)

I don't really mind it, since I can turn it off whenever I want. However I dont really like that the aux battery can cause problems even if I never use the ESS.

Be careful there - people say that but the main battery has been shown to be just as problematic. Jeep uses cheap batteries.

Here's a point of reference for you on that -
My wife's JLU several days ago was giving her the "auxiliary switches unavailable" message. It would disappear and then reappear.
Then a couple of days later, it happened to her again.
I checked battery voltage 12.0 volts.
So - the aux battery was bad, right?
Wrong - there is no aux battery on her JLU because it's a 4xe.
If you go to the 4xe forums that are unrelated to this group of forums, you see many people complaining about dead or problematic 12 volt batteries - they don't have ESS and don't have any auxiliary battery.
I have a feeling that I'll be dealing with a bad 12v battery in her Jeep after she leaves for her trip and she won't be needing it for a while.
There are a number of forum members here who have had the main battery fail - while the smaller auxiliary battery checked out ok.
But we know how the internet is - someone reads it, it's gospel because they read it on a Jeep site and the person sounded like they knew all about it.
Ok, sure...........

I don't like it and switch it off immediately after pressing the start button.

But sometimes I leave it on just to check if it is still working and have to admit that it works great.
Seamless with no interruptions as if it is not there.
So technically the implementation of the ESS is well done.

You wanted a poll, so I made one. A simple, black and white poll.

You should have made a poll asking " How many of you Jeep owners understand how ESS works" ?

I don't really care for it. It is a feature not applicable to me. Others may think differently. If CDJR had a choice, I do not think the JL or JT would have ESS. You can bitch about it all you want but the fact remains, ESS is a feature on our Jeeps.

Going blindly, removing batteries and pulling fuses thinking they are removing ESS is insane. Like ShadowsPapa mentioned, all that does is remove potential energy.

If you are going to delete your Aux battery, know what you are doing first. If you want to defeat ESS, know that you can only tell the system not to activate, via Tazer, etc.

On the 4xe, do you get the battery charging message or does it say " not ready". I had a 4xe rental that never said battery charging. Just not ready was displayed after warm up.

LOL - real scientific. A forum where people come to complain about systems. Yup, real accurate and scientific.

It's an opinion poll. Nothing wrong with it at all. A person's perception is their reality.
