Hey guys, It looks like this is an on going problem, I'm having the same issue with my 2019 tahoe Premier Sometimes I have to be only 10 feet away from the car for the remote to work. I trade in a 2016 Tahoe And I never had any problems with it, I mean the remote will work from literally a 1/2 mile away, I think is unfair to have to deal with this problem in a $70,000 truck.
And I think I'll have to agree with Artemiy Sevostyanov on the theory that GM Is trying to force vehicle owners on to buying services like internet or remote commands on the app that used to be free on my previous 2016 tahoe,
I really hope someone finds a solution to this problem....
