2025 equinox ev- OnStar Telematics module - no dates for backorder part is unacceptable
This is currently happening to me. I traded my 2023 Sierra on a used 2025 Sierra EV last week and was not able to setup OnStar after multiple attempts. Onstar green light is solid but it doesn't connect. Dealer I bought it from diagnosed a bad telematics module yesterday (6/18) and placed part order. I also found a Service Bulletin issued May 26, 2026 that stipulates dealers are not to sell any new or used vehicle with this issue. Obvious the dealer I traded with is ignoring this communication from GM. Very frustrating experience since without Onstar the on the road EV related features do not work like navigating to charging stations or estimated charge on arrival. Given the posts in this forum I don't have confidence my wait for a fix will be short.
