over 1000 mi on my 3 week old gladiator: pros and cons

[DankjeeP]

First thing I do after starting is to turn that damn ESS feature off.
Last thing I want is that stalling feature when I stop.
Kind of a pita that it has to be deactivated on every start up.

As far as stopping then restarting when put in park - that's also the way they are. Everyone's an engineer except real SAE engineers according to the internet - just ask anyone - they all know better and can't figure out the why of things (mostly because they hate it so don't want to understand it, simply continue to hate and complain about it and how they'd do better)

What's expected anyway - when you pull up in your driveway and hit the brakes and stop - it's supposed to know you are home and not stop?
It's not supposed to restart when you put it in park?

Isn't that how other ESS vehicle systems work?

You just have to be quick with the shifter when putting it in Park.
Or you can slip it into Neutral or Manual mode as you roll to a stop in your driveway.

I smell another "last Jeep I'll ever own" thread

Or another ESS thread... ?

 

[Jeeperjamie]

Wow another one of these threads. Pros and Cons are different for everyone, and ones like this make me laugh. I guess people don't do research anymore before jumping into buying a vehicle because if you would have you would of known about the ESS deal before you bought it. How long did you test drive it before buying it and why didn't you ride in some stop and go traffic. If I can't spend 30 to 45 minutes up to even a night take home in a vehicle I plan on purchasing then the dealership doesn't want my business. The ESS does what it's supposed to do and if you don't move to where you can get some speed up then it will not keep turning on and off and off everytime you move a few inches. That would be the dumbest engineering ever and probably a nightmare on a starter and the battery that is for the ESS. As far as keeping it clean, that's the joy of owning a jeep, especially a Jeep Truck, it's going to get dirty and it's going to be hard to keep clean. If your worried like that I suggest ceramic coating it, parking it in the garage and only driving it on sunny days, if you do that then it will more than likely stay in pristine conditions.

What are the projected fuel savings for ESS? 2%? That is .34 gallons saved at 17 mpg. All vehicles achieve 0 mpg when stopped, engine running. So, how much fuel is needed over time to idle? I doubt a 3 minute idle time would consume more than a cup or two. Engineering smoke and mirrors, IMO. Deactivate the feature and drive on.

I guess if your everyday use case for a truck is holiday light shows, your ESS complaints all makes sense. Somehow I doubt that's the case, though, so using a holiday light show as a basis for judging the truck is asinine.

If you truly bought it for going through light shows, might I recommend a EZ-GO cart instead.

Non engineers making statements of fact about actual engineers is generally amusing.

Never will you see more vitriol and confident yammering.

You will also never see ignorance showcased with such clarity.

Literally no basis nor understanding of how stuff needs to actually work in the real world, yet they make statements like "this must change !". Or, "those engineers need a career change !".

Read a little, hit the car wash. Problems solved.

True that.....but it's not really a first world problem so why bother with something so tiny. Get annoyed over axle leaks or the price of goods instead.

Nope. Edmonds did real world testing and got 8-10%. Others have found similar results with scientific testing. Again non-engineers guessing in forums.

So I think we have a few things going here:

1. OPs lack of understanding of what ESS is and how it's SUPPOSED to work.

2. His disregard of info presented to him about its proper operation.

3. His not taking into account how engine break in and fuel mileage works.

I don't think we can help with 1/2 because it's already been explained, he just doesn't like how the system works.

For the fuel mileage, it will increase OVER TIME. No vehcile will give you peak mileage brand new, again, that' just not how things work despite how much we want it to work that way. The engine and parts need time to break in properly. The only vehicle you'll get peak performance from factory will be a battery operated car.

You'll notice that after about 5k, 7k, 10k, 15, and 30k you'll see a decent bump in fuel economy. I believe I see best after 30k and that's when you start to get real peak economy. Also keep in mind that right now most of the country (I'd suspect FL too) has switched to winter blended fuel, so you're going to take a hit there on economy.

Between winter fuel and cold temps in the winter (I admittedly get colder than you will) I drop 2.5mpg easy. Same route to/from work every day and I don't usually let my truck idle to heat up so that's not it. Also keep in mind I'm fairly certain EPA numbers aren't gathered with E15, I think it's pure gas, so if you have an E15 or high gas rating you're already on the losing end.

I hope you're able to listen to and digest what people on the forums are able to impart on you, some of these guys on here are really intelligent and know what they're talking about. If you have something that actually disappoints you with your truck we may be able to help, but what you're complaining about right now is from a mechanical and physics standpoint. The problem with those things aren't from the truck or nature, they're form unmanaged/uninformed thoughts and expectations.

Sorry if I sound like a dick but it's reality.

Provided you actually use it and PROPERLY you will see an undeniable difference in your economy numbers, idling tanks your economy, the ESS really does help a lot, try it next summer/spring and watch your numbers raise a good mpg or so. I posed on here somwhere what my numbers were for a few weeks without ESS and with ESS on my same daily commute, all things being pretty equal (maybe some small variations in weather conditions but nothing widely ranging). The results are real.

Or learn to modulate the pedal like a grown up and not just either smash it all the way or don't touch it? Braking doesn't have to be an all or nothing venture lmao.

And the PCM learns as well. So it's a double thing - MPG almost always goes up - at least some, due to the learning and wear-in.

I've not noticed any difference between ethanol blends E10 and 15 and see very little difference in 10% vs. pure in my own vehicles (in Iowa it's normally 10% unless you opt for the 15% which is well-marked with light blue and marketed as "88" or "Unleaded 88" because it is 88 octane vs. the 87 of 10%)

The cold weather has definitely made a difference.

Yup - learned that 2 or 3 Grand Cherokees ago - hey, this is cool - I can change how things work just by how I press on the brake pedal and come to a stop! Wow! (LOL - I laugh now looking back at that)
Fresh red light - I press harder let it shut off, a light I've seen up ahead that's been red for a while or I see yellow for the other traffic, I press more lightly and it won't shut off.

Isn't research asking the same question over and over again?

 

[WXman]

Once I read the manual and learned that 5 MPH is the threshold, I learned how to manipulate it to make it go into an ESS cycle more often. Even in the McD's drivethrough I will allow just enough space to get to 5 MPH quickly and then stop. I can make the engine shut down a few times before I get to the window.
