GMC PIT6455B (Version 3)
Thank you. I am willing to provide my VIN privately if OnStar needs it to review my individual vehicle.
However, my questions are not limited to my account or a single truck. They concern the publicly issued bulletin PIT6455B and the status of a remedy for affected 2026 vehicles. Those are matters that would benefit all owners experiencing the same problem.
I would therefore appreciate a public response addressing whether GM has identified the root cause, whether a software update is being developed or validated, and whether any estimated timeframe or updated dealer guidance is available. Account-specific assistance can certainly continue by private message, but the general status of this known issue should remain available to the broader owner community.
