Mine would come on all the time when not running ac and here and there when ac was on. Yeah I think same way but I did notice it dropped some on my mpg today when doing normal city driving errands gym etc. where the auto stop comes on at almost every light we’ll not today. See what they say Saturday since I got auto stop and infotainment issues

They updated my radio with a usb as well. It was attempting to acquire satellite signal even though I could hear a station fine, but could not change channels, also one time the radio would not power off until I shut off the ignition. Sometimes I think there’s too much technology in these new cars. One reason why I avoided the new Ram, even though I love the interior, I just didn’t feel comfortable to buy one.

Auto Stops may not occur and/or Auto Starts may occur because:

. The climate control settings require the engine to be running to cool or heat the vehicle interior.
. The vehicle battery charge is low.
. The vehicle battery has recently been disconnected.
. Minimum vehicle speed has not been reached since the last Auto Stop.
. The accelerator pedal is pressed.
. The engine or transmission is not at the required operating temperature.
. The outside temperature is not in the required operating range.
. The vehicle is in any gear other than D (Drive).
. Tow/Haul Mode or other driver modes have been selected.
. The vehicle is on a steep hill or grade.
. The driver door has been opened or the driver seat belt has been unbuckled.
. The hood has been opened.
. The Auto Stop has reached the maximum allowed time.

Thanks for this. The service advisor said in a generic overview the auto stop needs certain perimeters but this is more helpful. I wonder why they seemed to change how this works in the Sierra. I’ve been in several different makes of cars with it and they come on everytime without fail. Even my wife’s Terrain like I said earlier.

The Terrain also has a list of conditions that will cause it not to stop. Perhaps you've not been in it when one of the conditions was present?

What year is the Terrain?

Online 2019 Terrain owners manual shows the same list of conditions as the cut-and-paste from the Sierra manual that was posted above.

It’s an 18. I swear it’s shut off every single time at a stop

Several of the items on the list are easy to test.

Just FYI - If you have a tow package factory installed, and you have something connected to either of the Power Connections, Auto-Stop should not work.

Thanks.

Didn't know that one!

(the others are straight from the list in the OM's.)

And it doesn't it matter if tow/haul is engaged?

Might have to 'borrow' swmbo's ride and check it out.

From what I've heard from others, no. One guy installed a 4-Pin Tester, and it disabled the Auto-Stop.

Check that the trailer brake is at 0% as well

Not sure if this has already been said, but when I put on my cat-back exhaust last year, it stopped working too. It only worked one time, but promptly came back on at a light with no changes from me. Might be part of the operating temperature range...but I live in the MID Atlantic. If you dont like the weather, wait 5 minutes.
