HELLO, BOYS!
Yes, same issue with my 2019 tahoe! My remote on 2015 tahoe worked from about 1/2 the mile... not kidding.
I have a theory though, GM just trying to push you to buy theirs services... like a remote key fob from the app on your phone for $10 or so. Guess what? it was free on my 2015 Tahoe!!!
No more freebies guys...
Shame on you chevy!
