I use it pretty much every day in my neighborhood. Temps have ranged from 65 - 78 without an issue. My understanding was as long as temps are above 50, should work. Maybe someone else has some insight, but I would think it would work.

Following. My stealth mode is also almost always “unavailable” and it’s been in the 80’s here since I picked up the car. It seems to work if drive the car a bit and then shut it off and try, but it never works first thing in the morning when it’s in my garage. Shuttle mode works fine and I can use it whenever I want. Can’t figure out what “condition” is causing it to not want to work on the initial start up.

My initial thought is it could be that the State of Charge on your drive battery is less than 21%. Shuttle Mode continues to work if the battery is lower than that.

Not sure about the OP but my hybrid battery has always been >80% and it still doesn’t work. Thought maybe it was because the front axle lift is set to trigger in my garage, but doesn’t seem like it if shuttle still works.

It also won't work with climate controls on (AC or heat), but if I recall correctly, it automatically shuts those off if they'd been on during the last ignition cycle. It would be something good to verify though, that those controls are off, to rule that out as the cause.

I’m going to test it but this might be it. You do not need the seat belt buckled to use shuttle, which is why it’s labeled “for off-road use only”. I have the buckle to drive turned off but I didn’t realized stealth mode would basically ignore that in order to be available.

Please let us know if that's it.

Its not. Only Stealth requires the seat belt to be fasten. I already tried several times in 2 days.

Getting more and more used to the transition between ice and ev mode in this car. At a stop light about a mile from home I out it in park, shut the ignition then toggle the mode selector to stealth, press the ignition button and Drive and go in Ev.
got it down to a science. I love it because while the engine is off all the air is circulating through the engine bay and heat escapes. Less cooling down in the garage.

nothing. But shut ignition off. The second that you do that you turn the mode selector. It takes about 1.5 seconds for the cluster to react and select stealth or shuttle or normal. i left my foot on the brake the whole time.

Stelth Mode Not working is "normal"
I had a problem with Stealth mode not working and took it to my dealer. He gave me TSB 6743429 that describes the problem. it says the following: "Both "Stealth Mode" and "Shuttle Mode" are intentionally unavailable for many different reasons by design. This is considered normal operation."
It goes on to say
1. The outside air temperature must be over 50 degrees F as determined by the vehicle.
2. The high voltage battery must be > 65% state of charge.
3. 12v Battery > 65% AND that this parameter is not displayed to the customer.
4. 12v Battery Temperature > 41 degrees F AND that this parameter is not displayed to the customer.
5. Parked on a grade < 12%
6. Fuel level > 8%
AND "Other hidden internal factors determined by various control modules."
So, the bottom line in my opinion is that if it doesn't work, just don't use it. That's too bad! GM should tell us that BEFORE we buy the car. That was an important feature for me because I often leave home before our neighbors are awake and would like to have that working all the time. GM should tell us that it is a great feature that might not always work and is unpredictable.
