Please note: This submission is in hopes that someone at Chevrolet is monitoring this forum for ideas.

AutoStop. Some people love it, others hate it. Chevrolet has decided we will all love it and have made it to default to on at every ignition start cycle. They have provided a switch to turn it off, but at every restart, it will be back on again.

I have had a recent trouble that might involve AutoStop. I am turning it off at every restart (that I remember to).

In today's electronic world, now even cars can have their software updated while sitting in your garage. The Trailblazer is one of them. I am trying to suggest to Chevrolet a software fix for the AutoStop default. All things hardware already exist. A rather simple fix: Revise the software so that holding the AutoStop button for more than 3 seconds flip-flops the default from on to off or off to on. I.E. AutoStop is currently in the on position, hold down the button for 3 seconds and now the default is for it to be off. Hold down the button again for 3 seconds and the AutoStop will default back to on.

You've also got some queer logic for the AutoStop button light. When Autostop is on, the light is off. When Autostop is off, the light is on.

Chevrolet...are you listening?

I just got into the habit of turning it off when I get in. I think it should be that you turn it ON when you want to use it though.
I agree, it should should be off by default and then push the button when you want it on. Maybe you could rewire the switch to operate backwards?

My assumption has always been that the auto start/stop systems default to "on" whenever the car is started because of efficiency and emissions testing, which I presume generally tests vehicles in the default state.

That said, I also assumed the same was the reason the AWD function on AWD models defaults to "off" when coming out of the factory. (Alas, having the AWD system turned off is bound to improve fuel economy.) However, the AWD function WILL remain "on" even after restarting the vehicle (if it had been selected before shutting off the engine), which throws a bit of a wrench in my "default state" theory. Perhaps the rules differ for different types of systems.

It’s an EPA emissions credit Chevy is grabbing with this. They can then use the credits to supplement a guzzler model down the line.

if start stop defaults to off. No extra emissions credits.

emission credits are a huge deal. Tesla sells 100m dollars worth to fiat every year.

cap and trade they call it

I m glad that they give us an on/off option. When I took mine in for the brake recall, I was given an loaner 2021 Traverse and I did not find any buttons for shutting it off. That was annoying.
I have become so accustomed to push button to start engine. Push button to shut off auto start/stop. that I don't even think about it anymore.

I guess, let’s be happy they have us a button. Many vehicles don’t have the option to disable auto-off.
ideally I would like it for them to make it for us to disable it and keep it disabled.
But you are right, it could be as easy as Chevy pushing out an update to allow that to happen.

Has anyone checked if there’s a possible fuse pull for this ?

Chevy won't turn it off for us. It is a EPA thing for the Auto folks to save money via gas/emission savings i think.
Exactly and there's emission credits GM gets for having their vehicles equipped with auto start/stop feature. At least we have the option to turn it off as many vehicles don't. Those bypass switches that some companies sell are just simple relays that automatically turn the switch off when it detects power, basically the same thing that happens when you push the button to turn off the feature.
