Whats is your opinion the jeeps engine stop start system?

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

Jeep are practical= fake news

Best thing I ever did was purchase a Taser to disable this feature (well, for that and to "black out" the backup lights so it won't blind the rear camera). I don't mind it as a feature, but please give me the option to permanently disable in the software.

I turn the stop start off every time I start my Gladiator up.

but I had a tail light out...I should say BRAKE light out (LED, aftermarket) a car comes up behind me, I hear the tires screech, same scenario- wait for the engine to start, and wait to be able to drive straight out of that situation!
...................
Another pet peeve: A brake light not working if that turn signal is operating. If I am turning Left, I put the Left turn signal on. That brake light turns off, the Right side stays lit. (visa-versa for the Right turn) I dont like this atoll. In the case above, my Right side lamp quit working, so the guy behind me had no brake signals showing. Is that a Dodge thang, or has it always been like this?

First - there are millions of cars and trucks with the "American" type tail/brake/turn light system. The guy behind you was a moron - plain and simple. He wasn't paying attention - the turn signal should have been enough. Bet he was distracted or approaching too fast, or both. I'd also bet that even had all lights been working - the moron behind you would have done the same.

Turn signals have been like that since they were first installed by the factory dating back 80 years.
The system originally worked when the turn signal switch put a "flasher" in the line to that side's brake light bulb.
Modern systems work by the BCM being told to interrupt the signal - flashing that side's brake light.

The "Euro" system came about in the 1980s when they added the amber turn signal bulb and left the brake light bulb alone. In the 1980s you needed to buy an adapter to convert a euro style car's turn signal system to work with a trailer with standard tail/brake/turn lights.

I believe the JT already has the euro wiring in place - you can swap out tail lights to the euro style with the amber turn signals. Likely can be bought from Jeep, or a 3rd party replacement.

There's a good youtube video put up by a young fellow who talks of this exact thing - the interrupted brake light vs. a distinct turn signal bulb in amber.

Aside from fuel savings. Lake Speed Jr had a video with a Ford guy showing 7k miles with out start stop and 7k miles after the new oil with start stop on. When start stop was off for 7k miles it had more wear due to primarily more fuel dilution. So leaving start stop on had less wear metals than off.

That's points I've been trying to to make forever. But no one wants facts. It's pure logic based in science and experience and training. Maybe some are actually intimidated by the latter two?

Must.....resist....stating the obvious......shutting down......

He is the oil nerd.

I question how effective it can be in saving gas, when the system never lasts a complete cycle of traffic lights?

Easy to disable after starting the vehicle. I move my finger to the right about 6 inches and push the button. It's muscle memory now and I don't even have to think about it.

Word of the day - cumulative.

In one single instance, a few seconds of turning the engine off probably doesn't do much. Add that up over days, weeks, months, years, it makes a difference.

You either have a system issue, battery issue, or stupid long lights over 2 minutes!
Mine holds in "off" for a good 2 minutes easily. The only time it won't is if it's really cold and can't keep up with heat, or really hot and needs AC to meet my temperature choice inside. On moderate days, it keeps up find and works the whole light cycle.
When it's not functioning - battery low or whatever other reason, I can literally watch the average mpg drop - a fair amount. My wife and I have both noted how much it drops sitting at a long light vs. when it's functional.

Mine will keep above 12.3 volts for many lights, the lowest it's ever gone has been 12, but it bounces back quickly. Keep in mind - that voltage shown during a stop is with the load of the vehicle across both batteries - so the actual BATTERY voltage isn't that low. If it shows 12.2 volts, that's with a load on it, tale that load off and it would be much higher. In reality, you are not really dropping actual battery voltage that far - it just looks that way and scares people who don't know batteries and electric systems.

Oh yea we have some ridiculously long red light cycles, one I’ve timed nearby taking a left on a local 4 lane with dedicated left turn with reg or green arrow, or right turn anytime it’s clear. That one has like six light cycles! The worst part is that left green arrow only lets maybe 5 cars in line through if every driver is awake! The big you are 6th you get stuck again for another 7 minutes!!!

Interesting observation and it makes sense. But a sample size of two is hardly enough to come to any conclusive result. The one with more wear could have just been a Friday build.

Not that old friday build conspiracy BS again.... LOL Wow, it just keeps getting more entertaining.

In reality that guy has demonstrated with numbers what we have been saying for many years that is already supported by science and logic - idling leads to fuel contamination which in turn leads to oil dilution, more wear, and the formation of acides in the oil.
I don't get there resistance to logic, engineering, science, and actual proof from people who know vs. the crap coming people who simply hate and base their "proof" on nothing at all.

Besides - looks to me like it was the same vehicle, not two vehicles....... so there goes that old QAnon build on a Friday bunk.

I bet a few here also believe a CAI will increase useful HP on these engines, too.
