Auto Start Stop Timing

[TimmH]

I've gotten used to A.S.S. (Aptly named I must say), but am I the only one that thinks a 3-5 second delay on it would be better. Many times I pulled up to an intersection, or in traffic, and in the mere second I came to a complete stop, the engine stops at the same time I take my foot off the break.

And the one that really kind of bugs me, is when I pull in to a parking spot and it shuts down before I can place it in park, at which time it cranks right back up again.

Seems a short 3-5 seconds delay before it stops would be beneficial.

What I have noticed and believe others have pointed out on the forum is that the engine cuts immediately if you apply heavy brake pressure when coming to a stop but it typically remains running if I use light brake pressure. Give that a try and see if it works for you.

Agree with this, light brake pressure if you know you’re not stopping for long will keep it on

Does anybody have a problem with their A.S.S. stopping and not restarting? I sometimes get the warning light
And sometimes it just stalls out. 2019 Sahara. Something comes up about the hood. Dealership replaced hood sensor and still have problem.

Sounds like you need to leave it at the dealer until that’s fixed. That’s not safe.

Couldn't figure out for the life of me why sometimes ESS wouldn't kick in. Turns out I was only on the brake hard enough to keep from moving forward. A little more pressure and it shuts down.

Now I know when I'll be at a light for awhile I'll push down harder. If I know it'll only be s short while, I'll go light on the brake to keep it running. Very cool.

I totally agree! Maddening for it to shut off as I'm parking, only to turn back on before I put in Park and furn off. Need a delay!

I will try that tomorrow. Thanks!

OP you are right. It is junk. I’ve had 3 vehicles with this feature. Jeep's implementation is by far the worst. I just push two buttons when I start now. One to start Jeep, one to turn it off.

I've asked my dealer if they could place a delay in the system. Unfortunately, they said they couldn't. Too bad, if there were a delay, I'd use it more.....so very tired of placing Jeep in park to have it start-stop while I'm shifting into park. Unbuckling the seat belt while coming into park does work, but I'd forget that sometimes. Better just to hit the disable button when I start the jeep and not use it at all. Poor design!

Since we've already covered the light brake pressure for quick stops, let me address the parking situation. When I park, I shift into neutral as I stop(less than 1 mph and foot is on the brake). The ESS will not autostop if the selector is not in drive. Once I am fully stopped I complete my shift into Park, then shut the engine off.

One shouldn't have to change the way one drives in order to accommodate this stupid system. The same thing happened to me the other day--I was literally stopped for about 1 second but in that time the engine shut down and restarted. Dumb! I was actually just as annoyed with myself for forgetting to push the opt out button. Gotta get that Smart Stop Start installed ASAP!

Its the best way to use the system effectively. Light pressure to avoid an auto stop at a stop sign (And we all just roll through these anyway) and once you're at a solid red light just press a little more to have the engine shut off.

Yeah, I can see it already: "Well, officer, I rolled through that stop sign so that my fancy shmancy eco-saving auto stop start system wouldn't kick in. Really!"

lol, I didn't say blow through, but honestly do you come to a solid absolutely no movement stop every single stop sign?
