Thoughts on my plan to avoid future Start/Stop issues???

[Heimkehr]

My idea is this: after hitting the start button to fire the old girl up, immediately and habitually turn off the Start/Stop feature. Seems to me it serves the same roll as an alteration, without fidgeting with the electronics or programming at all.

Is there something I am missing

Consider the wear to the non-ratcheting dashboard switch that will occur during the lifetime of the vehicle. It doesn't appear to be a particularly robust fitment. Will it weather constant use over the long term?

That's what informed my decision to spend a C-note for convenience.

Yes, eventually the original ESS battery will be removed from the vehicle. The linked harness was a non-invasive stop-gap measure.

I barely notice the start/stop with the etorque. Buy a tazer and just let it remember the last state when it was shut off plus all the other great features it has especially if you plan on lifting it.

I've been reading this forum daily since I put a deposit down on the new 2024 Rubicon X 2D 3.6, and I notice a lot of issues with the start/stop system. This is a feature I don't happen to like at all anyway, and I certainly do not want to invite future battery or electrical issues, or to put unnecessary wear in the engine continually starting. I've read about getting devices to permanently turn the feature off by remembering the last setting (off) on start up.
My idea is this: after hitting the start button to fire the old girl up, immediately and habitually turn off the Start/Stop feature. I am the sole driver. If I forget, I hit the button to disable when it turns off, reminding me (which rarely happens after the first few days of driving) that I hadn't done it yet. Seems to me it serves the same roll as an alteration, without fidgeting with the electronics or programming at all.
Anyone else following this plan? Is there something I am missing by making a semi-permanent solution with reprogramming, etc?

I also have etorque, can't feel the engine start, i do feel the shutdown though. I do what you do, I may change that if I am in the city, but out here in the woods, my shortest stretch is 12 miles, and I would rather not have the engine shut down at a light only to have it restart 10 seconds later if I just came off a long hill climb.

If I own a vehicle under warranty, I don't mess with it since about 2000.

Gotcha. I don’t have an e-torque though.

Etorque 3.6. While under warranty I'll keep
pushing the button. Don't need any self induced electrical issues under warranty. Etorque is just about not noticeable on most start/stop occurrence though. I do push the button with the mindset that if the engine doesn't stop then oil is always covering the cams/lifters and therefore should reduce the chance of failure. Who knows but that's what I do for now.

Keep on mind when reading forums: For every one person that posts that they have an issue with their vehicle, there are thousands who do not, and the vehicle works perfectly. No one posts about how well their vehicles run. They only post about issues they have.

There is no additional wear and tear on the engines with the auto start/stop. The engines were designed to operate that way.

Yeah, but I don’t like it. I can’t get past thinking that the engine just died. I grew up having too many cheap ‘80’s vehicles where the engine would die. PTSD

You'll solve nothing. The problems people have isn't with the Start/Stop engaging, but with two dissimilar batteries connected in parallel. The batteries are still connected this way whether you push the button or not.

His rockers and cams will probably outlast the warranty period though.

Hydrodynamic bearings require rotation to entrain oil. Nearly all the wear occurs on start up and shut down.

Engine stop start systems are afterthoughts to help meet corporate average fuel economy targets. They are compliance features. They are not in the customer's best interest. Your engine absolutely will last longer if you disable stop/start. Whether it matters during your length of ownership - who knows.

The engine doesn't remain off long enough for all the the oil to drain out of lubricated components. 30 seconds to 1 minute seems to be the usual time for me before I'm on the move again. And thats if the AC/Heat doesn't kick it back on sooner than the light turning green.

Without oil pressure or rotation, the oil wedge is collapsed.

It's true enough that a starter rated for a more severe duty cycle was specc'd in recognizance of the ESS functioning.

When ESS is present and operating on the vehicle, how are any of the Wrangler's ICE engines in fact designed to compensate for the absence of circulating oil when the driver presses their right foot the nanosecond after the engine restarts at a green light? Posts 24 & 26 add appropriate context here.

80% of engine wear occurs at start-up. While that wear is probably reduced relative to what remaining film of oil is on the cylinder walls of a warmed engine, it is still occurring.

I thought I remembered when the JL first came out that you could disable start/stop by disconnecting one of the two hood closed indicator buttons. I'm sure you needed to disconnect the proper one but certainly cant remember that. My Jeep does not have it.

I got the 7 year/100k warranty, they better!!!

The engine is started and idle by the time your foot is actually off the brake pedal. Nanosecond is a bit of an exaggeration.
