Yes. Our 2018's carnet subscription ran out this past weekend, and when I called them, I was told I could not renew. I didn't realize how much I relied on checking the charge status until it went away!
AT&T may be forced to delay their disablement of 3G, given how many cars and other devices (not just e-Golfs) are in this same situation. But even if that comes true, not clear that CarNet will allow for renewals.
