Condition/Concern
Some customers may comment that the radio screen is blank with audio, has locked-up or is frozen. This may have
led to a battery drain at one point in which the issue is resolved afterwards. No OnStar® interaction is required to get
into this state.
Recommendation/Instructions
Do NOT replace any parts at this time. If the vehicle is currently in this state, a press of the call answer/end button on
the mirror will correct the concern. This is a known software issue under investigation that will be resolved via an
Over The Air process when available.
Note: This PI should not be used for any unduplicated battery drain unless the customer specifically mentioned the
radio lock-up.
If pressing the call answer/end button does not solve this issue, refer to SI and continue with normal diagnostics.
