OnStar Module failed end October - 2025 Equinox EV LT2

Dealing with the vey similar issue here, 2025 Equinox EV RS purchased in May. I put just under 12,000 miles on it and in late October the telematics module failed. Brought into dealership service center on November 10th and was told it needed replacement and the module was backordered. I called back to check a couple weeks ago and they basically said "no ETA don't call us, well call you". Incredibly frustrating as I have a long commute each day and like to rely on the nav system to have an idea about traffic and my range etc. I feel naive for thinking that I wouldn't have an issue with my first ever brand new car and frankly am really bitter about the whole experience. I don't have any words of help here but completely sympathize with your experience. It just sucks.
