GMC PIT6455B (Version 3)
Thank you for the response, Sam. I appreciate the acknowledgment, but affected 2026 owners have now been told for months that engineering is investigating.
Can you provide any additional detail on the current status, such as whether GM has identified the root cause, whether a software update is in validation, or whether there is any expected timeframe for a remedy?
In the meantime, owners are continuing to experience intermittent loss of OnStar and driver-assistance functions, so more specific guidance would be helpful.
