I have an older Trailblazer LT with OnStar. I’ve never had an active subscription with it. However, last April I received a letter from my insurance company saying my mileage for 2023 was estimated to be 34K miles and they were substantially raising my rate. I did 34K/4 to get the 3-month total of 8500. It was at 8600 in the first week of April. Right on the money -my money.
