Nope, no recalibration if the same camera is used and put back as it was found.

Thinking someone paid for a service they did not need.

Jim   watch this video. Sound isn't too good but if you compare the (2) trucks/windshields, they are different

Correct, if they put the windshield on the left in your truck, all the recalibration in the world would not help because the cameras view would be blocked.

 

Not sure if have done so, but go stand in front of your truck with a flashlight and shine it in the "hole" and you will see your camera. It just needs a clear sight path to work. (Truck on the right in the video).

Not to belabor the point/issue, buy I checked my truck & it appears that the rearview mirror & video camera are all mounted to the windshield. So the old one would require to be removed & installed on the replacement, which if that is the case, would require a "recalibration" by the windshield installer to remove any liability of the Lane Departure being set incorrectly. That's what was explained to me by Safelite when they installed the windshield on our X5 with this feature. That would hold true for GM as well. It's pretty standard procedure on all cars/trucks with this option.

Camera is never unplugged from vehicle, there is a bracket that is fixed to the windshield. The camera is taken out of the bracket, left hanging by it's power cord, and then slid into the new bracket never losing contact with the truck, that is why it is reused and not included with the new windshield.

 

I will concede this battle with one last question, did you ask why it has to be done, or just accept that the tech said it had to be?

anytime a windshield is replaced the calibration of the lane departure camera is required. Now will the system work yes but its basically the vehicle manufacturer covering there ass and if the system doesn't work properly they can turn around and say well its because a windshield was installed on the vehicle and the calibration was never performed.

Does not really answer the question of why does it need to be done?

 

What is done when recalibrated, other than being "recalibrated"? It is a camera that never loses power, and why would the factory glass replacement cause any issues?

The reason is, that the bracket that holds the camera, needs to be attached /glued to the new windshield, which will not be in the same location as the old one, nor will the windshield be exactly placed where the old one was by fractions on an inch. So, when the camera is reattached to the bracket/windshield, it is very likely NOT in the same location as before & needs to be "readjusted" electronically to know where the center & outside lines are. It's not a mechanical "line recognition" but an electronic one, so the technician has to hook up a portable computer to the car/truck & tell the camera where it is. He does this by driving the car for 15-20 mins to get it adjusted correctly. Otherwise the car's camera thinks it's in the same place as before it was relocated & a 1/4" move of the cameras from where it used to be will multiplied to where it reads the lines on the road.  

 

this video explains it better that I can. Hope this helps

      My brother has an Escalade. The warranty has expired so he told his wife to go to the Valvoline quick lube he uses some times. They told her if her car was a 2020 and newer 6.2 engine they wouldn’t touch it. Hers is a 2019, so they did the oil change.

      2026 6.6 L5P oil cooler leaking oil at 4,000 miles

      The oil filter has NOTHING To do with oil leak. GM sources parts from 1,000's of vendors and as with anything mass produced, flaws are unavoidable.    Putting a larger oil filter will do nothing but satisfy emotions. The OEM filter is designed for the engine and perfectly capable of handling the demands on the engine. Oversize oil filter could result in reduced flow and overall lower oil pressure.

      You're better read than that Atlas. 😏   British science fiction writer Arthur C. Clarke formulated three adages that are known as Clarke's three laws, of which the third law – that "any sufficiently advanced technology is indistinguishable from magic" – is the best known and most widely cited.   Stribeck and the pivotable Hersey Number isn't voodoo nor snake oil. That part is physics. It's what marketing and bean counters do with it that is snake oil and voodoo.    Stribeck is the relationship between Hersey and the Coefficient of Friction. Within the Hersey Equation if viscosity and viscosity is 'Dependent' on.......heat.......and.......viscosity index or the temperature to viscosity slope.    Specifically Hersey is the viscosity AT THE TEMPERATURE IN THAT LOCATION FOR THAT SLOPE.   Hydrodynamic lubrication exist when the film thickness in the location is 3X the Ra roughness of the surface. This is irrespective of the hardness of the substrate. To obtain that thickness X viscosity is required for Y velocity at Z load. That's a lot of moving parts. It is also impossible to maintain in an ICE but nearly possible with a turbine under constant load.    What does that mean? Error heavy and operate light. Wear is inevitable but the rate of wear and the milage obtainable are a function of prevailing conditions and HABITS. The only penalty is viscous drag and at fractions so low as to be well worth the effort. Double the life, half the manufacturing carbon foot print. Greed is the only impediment.    The materials generated by SwRI are the RESULT not an estimation or a hypothesis.    Don't delude yourself sir, EV's have as many pitfalls as ICE's. We just don't know what they are yet and it will take longer to sort as MARKETING and GREEDY CEO's have had more time to polish the turd they are selling.

      You can always count on greed to prey on ignorance and stupidity.    Friend bought a 2019 Ford Flex and asked me about using Valvoline R&P 5W30 in it. Told him give the miles on it and the fact it wasn't yet using oil that it was a good plan. He uses a Valvoline quick change shop for his oil service.   First they tell him that isn't the oil the OEM recommends. He told them he didn't care what the OEM thought. Then they floated the, "But it will void your warranty"    His reply was it's a 2019, there is no warranty and informed them their knowledge of the law was lacking.    Then they tell him 'But it will ruin your motor"!.    Mine to ruin he says. Finally they give in and charge him 150% the semi-syn price    Point it the brainwash is so embedded that even the service industry is drunk on their swill. The public is right behind them. Echoing the same lies on every forum and media platform. If the end goal is indeed EV then I'd say that ship is about built.
