2025 Blazer EV: Telematics Failure, No ETA, and No OTA Updates — What’s Going On at GM?
Just purchased my 2025 Blazer EV used on 5/2/2026. The dealer said they checked the car before I purchased it. Got home and found out after talking to on star that the car probably has a bad telematics module. Took it back to the dealer and they verified that the module was bad. Checked the my chevrolet app and the last it saw the car was 6 months ago. How the dealer sale a car that is not fully operational? NOT HAPPY WITH CHEVROLET RIGHT NOW. THE PART IS ON BACKORDER WITH NO ETA ON THE REPLACEMENT PART. You think with all the reported failures this should be a vehicle recall. As far as I'm concerned this is BS
