BUICK ENVISION 2023 UNKNOWN OR OTHER

Onstar module out. Car can not be detected of location. Can not use gps. In the event of accident onstar can not help me this is a safety problem for a woman especially. When it first went out the car would not cut completely off had to disconnect battery. The gps light stays on with a line through it. Canât use blue onstar button itâs completely out. Dealership says module needs to be changed. It has also affected other components of the car. I see this is a wide range problem. Dealer sell this as a safety component in the car but when asked about a recall they now want to state its its luxury.

I bought a used 2023 Buick Envision with 49k miles on it. It was not covered under warranty due to mileage. A couple of weeks after purchase the CEL came on. It was originally diagnosed as a bad battery. It was later diagnosed as a failed Telematics Module. I had the module replaced on 8/23/25 so it is not available for inspection unless the dealer has it. After reading many complaints for the same problem on many different GM cars I suspect the bad battery had been drained by the failing Telematics module. Although it did not happen to me directly others have reported the car dying in the middle of the road because the battery died. The car has only been inspected by two dealerships since my purchase. I am reporting this because there are so many others facing this problem. I live in Los Angeles and my dealership was able to get the part and replace it. So many others are not even able to get the part. Their lives are being negatively impacted. I hope you can gather enough complaints and force GM to recall these modules or come up with a solution. This is dangerous and extremely frustrating for many consumers. Thank you for your time. PS - I can provide the invoice for the module replacement if you need it.
