2018 Denali Rear Air

[JMV]

When I start the vehicle (remote or in person) its a roll of the dice whether the rear air turns on too. Sometimes yes... sometimes no. I don't want it on, repeatedly turn it off, only to have it turn on again upon re starting. I've checked the personalized settings multiple times; no to rear air on start up.
Is it a gremlin or am I doing something wrong?

I deal with the same thing in my 2019. My guess is it typically will deal with the remote start (there are settings for 'auto air/heat' in the remote start section). When I start it by push start, the rear air doesn't come on. When I remote start it (or when my wife presses the 'auto' or 'sync' buttons), I notice the rear air comes on.

I'll try playing with the Auto/Sync and see if that helps. Thanks.

Do believe you nailed it. Remote start 99.9% no rear air; start it yourself inside rear air comes on (as long as front air is on) 99.0%.
