Whats is your opinion the jeeps engine stop start system?

[ShadowsPapa]

Must be the same reason why your cold can of Coke’s got water dripping off the sides. So make sure you refill it with a little more water, before you drink it.

Uh, where does that quote come from? not this thread.

I'm glad that Jeep was nice enough to include a button that allows me to turn it off. I just wish that it would remember my choice of off and keep it off when I get in and start it up. My BMWs always remembered this choice. Why can't my Gladiator? I know someone will spout off something about a Tazer, but I should not have to buy something and keep it plugged into my OBDII port to override a setting that the car should be able to store.

Some law changed in 2016 or so, that required the ESS off buttton to reset to the default(active) after every shutdown. My 2015 Porsche, on the other hand, remembers the last position. It has remained in the Off position for over 10 years now.

Also why does my muffler drip water? does this mean i have to refill my radiator?

sorry, quoted the wrong guy. this is how Fake News starts

I don’t know that it causes any harm to the motor, as mentioned, lots of Priuses with lots of miles. But, when a hybrid restarts it doesn’t use a conventional starter like ours does, so my biggest ‘damage’ concern is the starter.
I don’t use it because I find pressing the button to be less of an annoyance than not.
I guess if I was buying used, and there were two identical jeeps from two identical guys, one that pressed the button every time and one that didn’t, I’d buy the one that never used start stop.

Just recently spent a weekend replacing the head gasket in a Gen 3 Prius, known for common failures, mainly from excessive expansion/compression of the heating and cooling cycles. The fix, was a better engineered gasket, and I feel sorry for the folks that had to pay out of pocket for 18 hours of labor ( like we were quoted) at nearly $200/hr. I know these 3.6s aren’t pared with a hybrid system in my JT, so it’s a different beast, but I do wonder if there are indeed other points of failures that haven’t fully been baked yet. Maybe someone here can speak to it.

I have a diesel and we are supposed to allow the turbo to cool down before shutting off the engine. So I just disconnected one of the hood plungers (cant remember which one) that disengages the auto on/off at stops. Been that way for a year and all good. Yes, I allow the turbo to cool down below 400f before I shut it off.

This same engine has been in use since 2016 model year Grand Cherokees with the same exact systems. (we had one of the first). It's the same engine as what our JTs have save for the sump capacity, etc.
9 years out the door. I wonder how many of those have over 100,000 miles on them?
The JT 3.6 isn't new - it was created in 2015 for the 16 model year.

And maybe that’s part of the point, is folks’ perception. So to you, it’s not new, and I’m guessing that you believe that you can count on it. For our house, and I suspect many others, our JTs are the first vehicles that we’ve had with ESS, so our perception includes a healthy dose of skepticism ( and maybe anxiety too ) for this new tech. Because it feels random, and doesn’t kick in at the same place on the road, with repeated trips, it feels weird. Some of us prefer control/feedback of things like gas/breaks/steering/windows/part-time-4wd/manual for their explicit, consistent behaviors… and then it takes time to trust the machine for things like ACC, climate control, and ESS, ore even full self driving. For those end user interactions where there is some higher levels of automation, those interactions really need to be so seamless that they almost become unpercievable.

On the Diesel - Actually works really well

On the 3.6 - Kinda annoyingly laggy, but not nearly as bad as any Jeep with the 2.4L engine

Exactly this. The 3.6 is a very well proven engine. Every Pentastar Upgrade engine is designed for ESS, and the failure rate of these engines is incredibly low when the number of them produced is taken into account. One of the design considerations was to make it capable of long term use with ESS. Special bearings, upgrades to the oiling system and starter were part of the PUG engine. The number of Pentastar Upgrade engines used in the Wrangler and Gladiator is only a small fraction of the total production run so far, far more are in Grand Cherokees and Durangos. I have no problem with saying that the Pentastar Upgrade is the best engine produced by Chrysler today. I would even put it above the old Slant Six, which was a model of durability back in the day.

Yeah but that one guy on the internet said his failed so they must all be shit!

I always hated start/stop in any rental car I ever drove. However, in my manual transmission Gladiator I don't mind it at all. I started out turning it off every time I drove but now I don' t bother. If there's any situations I don't want it activated I can just leave my foot on the clutch. So it only comes on when I'm at a rather long red light.

 

[Bbannongmu]

I have a manual transmission and a much heavier Centerforce flywheel. I hate the delay of Auto Start Stop - A.S.S. and use the Tazer to keep it off. I wonder if the heavier flywheel could cause problems in the long run if I were to use A.S.S. ??

 

[Volt0]

Yeah, I still don’t like the ESS.

 

[Tullyp]

Have a manual so not really a problem for me. It hasn't activated once in over 6 months and I'm glad. I have to actively try to get it to engage (which I don't do).

That being said, it can definitely save some small amount of gas, maybe .1 mpg on average city drive.

To those that say, "it causes no extra wear on the motor", I say that opinion goes against all logic. They had to beef up the starter and drive train to compensate for it. And since I don't use it, I loath knowing I have to replace two batteries instead of one when either one dies.

I have no problem with the principle of it. Some vehicles work better than others. BMW’s old system (no idea if they improved it) was jerky. I found that it was pretty innocuous on my eco-diesel when it worked. I had two issues with it, so I disabled it. It always seemed to be unavailable except when I pulled into the driveway, which is pointless and annoying. For an overlanding rig, I think the implementation makes it a liability. My dealership told me 90% of the warranty work they do on the Gladiator and the JL concerns the batteries. I was left stranded twice by a bad main battery, secondary to a bad aux battery. I disabled the system. I’d rather just have a hybrid with a more robust battery system or EV Gladiator.
