[OFFICIAL] Missing Camera Grid Lines & Blue Hourglass Icon (Surround Vision Glitch)

[Zane]

 

I’ve been seeing a lot of people in the community dealing with this issue lately: you shift into reverse, and your helpful camera grid lines are completely gone, replaced by a blue hourglass icon. Since it’s popping up so frequently, I put together a guide using a mix of personal owner experiences and GM’s official technical guidance so you know exactly what causes it and how to get it fixed.

We want to make this thread the central hub for anyone dealing with this glitch. If your truck is giving you the dreaded hourglass, drop a reply below and let us know:

• What year and model are you driving?

• What symptoms are you seeing? (Missing lines, hourglass, black screen, etc.)

• What was the fix? (Did a software update cure it, or did the dealer have to replace hardware?)

• Did you find any temporary workarounds?

Sharing your dealership invoices or what the service advisor told you can be a massive help to other owners trying to get this fixed under warranty.
