Rydogg said:

I called Onstar 2x and they said I needed to take it back in to the dealership. Does that sound right?

All -
Be careful with this one!
After my reprogram, I lost OnStar and WiFi modules. Took it back in. Dealer confirmed that recall work fried the modules.
Mine was the 4th one this advisor had seen. Best part...OnStar module is on backorder w/ no eta. Thanks GM!

• Update Process: The vehicle did not initially accept the update, so it remained overnight to ensure it was properly installed.

• Gridlines Missing: The gridlines that typically assist with camera views are no longer visible.
• Hourglass Icon: An hourglass symbol appears consistently across all camera views, which disrupts normal functionality.

• I seek assistance to resolve these display problems and would appreciate any guidance or support the team can provide.
• Please let me know how to proceed if additional diagnostic steps are required.

I wanted to inform you that I completed the latest update on my 2022 Yukon Denali. However, the update process encountered some challenges:

• Update Process: The vehicle did not initially accept the update, so it remained overnight to ensure it was properly installed.

Since completing the update, I have been experiencing intermittent issues with the vehicle's display systems:

• Gridlines Missing: The gridlines that typically assist with camera views are no longer visible.
• Hourglass Icon: An hourglass symbol appears consistently across all camera views, which disrupts normal functionality.

Initially, I referred to a message from July 2023 that addressed mirror misalignment, believing it might be related. However, after thorough inspection, it's clear that mirror alignment is not the source of these issues.

Next Steps:

• I seek assistance to resolve these display problems and would appreciate any guidance or support the team can provide.
• Please let me know how to proceed if additional diagnostic steps are required.

Thank you for your attention to this matter. I look forward to your prompt response to ensure the vehicle operates smoothly.

Best regards,
