Whats is your opinion the jeeps engine stop start system?

[Gator]

Worst feature is that ESS, I disconnected mine. You can't tell me your not wearing out the starter, engine, battery and fuel.

Yeah, I can but hey, the internet "experts" in all things electric and mechanical have a tighter grip on people so it won't matter. Love it. Those with no training or experience always win on emotional issues. Keep the expertise coming.

Your last quote is missing something and I not talking about " if it floats".

Yea. I definitely should have added that in. My boat is proof of that.

 

[Batterycap]

If you don't get it, there's no explaining it to you, sorry.

Acknowledged. That would be my response to if I made a statement for which there is no support. First deflect, then attempt to reassign the accountability. Got it.

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

LOL - as if scientific research is the ONLY method to gauge an "opinion"... And as if scientific research is the only way to gauge what people "think" or how they "feel" about impacts on their lives and wallets. Science is not the answer to everything and I would argue its not the answer to most things that don't require scientific proof to gather info. Like this poll...

Regardless of why it exists, it seems overwhelmingly that in this poll, people dont care for it. My wifes Compass had it and the first time it kicked in, we were like "WTF?!?!?"... Shut that thing off. And it remained that way for the rest of the time we had it. It has been disabled via Tazer on my 23 HA and I also disconnected the battery cable from it. Bcuz its a giant PITA. Doesnt matter to me what the science says. I dont want my vehicle shutiing off and restarting on its own, period. The 12% gas savings (if it would ever actually end up that much with my driving habits) isnt worth it to me. I suspect many other consumers feel/think similarly.

There ya go - something that at least makes sense. That's a thought that's at least well stated.

OK, I'll bite. No google, no bing, no other search engine - your basis for it wearing out the engine. Please explain your basis for knowing that it wears out engines. No quotes from other members stating the same thing.
I am really wondering where this is coming from.

I'll start with some simple things -
At an idle speed of 800 RPM, if the light is red for 30 to 90 seconds (here it runs 90 to 120 seconds in some cases, but I'll stick with 30-90). You have the engine running against the load of the transmission (automatic) for 400 revolutions to 1200 revolutions.
During that time, you fire each injector 200-600 times (they are mechanical devices, electrically triggered) You operate the exhaust and intake valves for each cylinder that many times, the valve stem traveling in the guide, and the followers running on the cams.
You have each piston with the rings on said piston running under the load of compression and then combustion pressure, 800 to 2400 times (for every revolution of the crank there is an up stroke and a down stroke. Piston skirt and rings rub on the cylinder surfaces, yes, with a layer or film of oil, but it's still counting to some extent.
You are loading the bearings with the load of compression, and then the load of, idling, light loads, about 300 psi. Take that 300 times the square inches of piston surface area for the force shoving down on the rod and against the rod journals. Roughly 11.25 square inches for a 3.6 I believe. So 11.25 x the 300 = 3375 pounds of force coming down against the rod. (math majors can check that work!)
That's happening about 200 times a minute.
There's fuel contamination during that idle time as well.

So, with that in mind - is there more wear with it running, or a hot ESS start where the crankshaft probably rotates once or twice before it's running. (with zero wear while it's off)

Just trying to see where the "more engine wear" is coming from.

If you hate it, you hate it (like BaneKotaKeena has said, and those who simply don't have the traffic patterns where it even makes any sense at all to let it operate - that makes sense) but I'm trying to see where the experienced mechanics here are stating increased wear, etc.

No Alta Vista or Ask Jeeves either?

Probably the same as most regulatory-induced choices we have to make.

Most folks in the U.S. completely fail to use turn signals, yet manufacturers keep putting them on vehicles for some reason.

If Chrysler was allowed by U.S. DOT to make turn signals a $500 option, would you keep the cash?

Nah, I use the indicators all the time, even to say "Thank you", so those are useful. Lane departure, auto-brake, so on, are not useful, to me. But, a buddy did have the lane departure save his butt. Of course he could have chosen to not drive after a twenty hour work day; there is that too.

The point, even at $5/gal gas, in the lifetime of the vehicle, are you going to break even?

I will turn off a vehicle when I know it will be stopped for several minutes, even on a hot day. I will not, like ESS, turn off a vehicle at every stop light and stop sign, to save a few seconds of fuel.

Well................ How about duck duck go?

It was actually a serious question. There's enough who say "it causes.........." very firmly and with great conviction and I'd like to know where that comes from.
Apparently they are more informed about such things and I'd like to gather that information.

 

[Splenda]

I always try to remember to hit the button before I get to the first stop sign or stop light.

I dont think there is a law that says ESS is required when making a turn... or a Stop... as it were so not quite the same thing.

Ehhh, you're technically still allowed to use arm signals, at least in Texas, but that's entirely missing the point...

You sound like a politician. Should run for office.






Maybe dog catcher.

The ESS system is garbage. I don't care what anyone says or reads especially in a manual. Nothing worse than coming up to a red light popping in neutral for a split second having the truck shut off then immediately have to restart as the light turns green before the engine is even all the way off. When wheeling offroad the constant "reminder" that startstop is not ready is also garbage. Worse of all it takes about 30,000 to 40,000 miles of "driving" to save enough fuel just to cover the cost of one ESS battery replacement. I didn't even hit 20k before my first battery failure.
