Got this suburban in December 2024. i have had drained batteries almost twice a week. I replaced the battery and then had the new one tested; it passed. Then I had the alternator tested, and it also passed. You can see the battery gauge on the dash, and it constantly charges between 13 to 15 volts. I found a drain from the radio and pulled the fuse; it seemed to help but did not cure the issue. Live data from driving and monitoring says the system is at 14.2 volts. I have taken to a local shop that specializes in electrical issues, and they said the radio sounds right, but they could not replicate it. Is there something i am missing? Please help.
