2020 RST - issue happened the first week I had a truck. Backed the truck into the garage screen black next day battery dead. Aside from back screen I get an extra pre step to the black screen the wifi modem or router will not initialized. One day I have LTE the next morning it doesn't turn on. OnStar tried resetting it, they can't , pulled the battery everything came back. Restarting the truck fixes the black screen but 27 times over owning the truck less than 2 months is ridiculous. Also it hates remote starts. If I remotes start it just accelerates the problem to no internet or faster black screens.
Took it to the dealer - feedback we can't replicate the problem bring it in under the condition. Technician took it on test drives. Super angry.
