Onstar Module failed 200miles into ownership
All these NEW 2025's with failures. I'm curious. It worked when you took delivery and just failed without ever having let the dealer touch it in ANY way AFTER you took delivery? Most of the original failures that started appearing here all seemed to be related to a software update the dealer performed. Presumably that update could only be performed at a dealer. If OnStar is delivering over-the-air updates that's killing the units, that's ridiculous.
I believe these can automatically be done over wifi so does not have to be done at the dealership. My partner works at a dealer and is having major issues with a 2024 suburban. Found out it did an update over night then wouldn’t start. Seemed like a bad battery so they replaced it. Now it’s throwing codes like crazy and something about the modules. Sadly he didn’t even have this information. He is being blamed for doing something wrong and stressed out. He knows he did nothing, what he repaired has nothing to do with any of these parts. I felt so awful seeing him stressing I got in google to see what I could find and lo and behold I stumbled up this! Sure sounds like a lot of issues he has been having but much worse.
