2023 GMC Sierra 1500 — windshield replaced — does camera calibration matter?

RotorOwner247Community StarterFeb 7, 20262023 GMC Sierra 1500 AT4Chicago
A new windshield is installed and there is no dash warning, but the shop recommends camera calibration. If the manufacturer procedure calls for it, would you do it even when lane-assist functions appear normal? I am in Chicago. I am trying to get the facts straight before spending money.

Thanks — that narrowed it. I'm going to try the simpler check on the 2023 GMC Sierra 1500 first. This is me being the wet blanket on purpose.

Write down what you already tried. A second data point from another 2023 GMC Sierra 1500 owner helps more than a generic diagnosis. Then you'll know the next fork. Just my two cents from doing this recently. I'd sleep better after that step, even if it finds nothing. This is the version I'd tell a friend.

Owner notes beat generic advice here. On the 2023 GMC Sierra 1500 in Chicago, I'd fix the thing you'll notice every day before chasing spec-sheet extras. I'd do that before spending real money. On “windshield replaced — does camera calibration matter,” that was the fork that mattered for me. Stop there until you know. That's my plan before I call anyone.

Useful. I'll report back after I verify that on my 2023 GMC Sierra 1500. If the story changes I'll post the new data.

Don't overfit one forum story to your car. If it still isn't clear on the 2023 GMC Sierra 1500, a specialist hour can be cheaper than another round of parts. Then you'll know the next fork. Do that first. That's coming from doing this as an owner, not a shop. If the story changes I'll post the new data.

That's my plan before I call anyone.
