Yes, unfortunately that’s how all the OEMs are evolving. Even relatively small upgrades or repairs are very difficult or not possible at all anymore due to the “software lock”.
I’m still hopeful someone will figure it out. Its the only thing that bothers me on our LS. Not worth upgrading to a Yukon given the MSRP increased by ~$5k, not talking of CA taxes. Does the Yukon even come with the front bench seat option? That was the main reason going with a “base” model.
Yep - I have an SLE w/ 9 seat config. It was our main reason as well to get the base trim - ended up finding the Yukon, but we would have taken the Suburban as well if we found one with what we wanted (Diesel, Tow Pkg and 9-seat config). If I remember correctly the things you get on a Yukon XL that you don't get on a Suburban are:
-Digital Dash
-10.2" Infotainment (Also gives you the trailering menu to setup profiles, sync trailer tire tpms, etc.)
-Fog Lights
-All LED lighting (front and back)
-Better looking 18" wheels IMO
-More chrome trim around side windows
-Chrome dash adjustment knobs HVAC, Driving Mode, etc.
