Random “Service front camera” warnings in good weather . Cleaned windshield. Removed camera, cleaned lens. Cleaned inside of windshield, checked wiring. All looks good. Camera is mounted nice and snug.

I bought it a year ago from the dealership. They took care of at least three recalls at that time. I would hope they took care of whatever else needed to be done.its worked without issue until a couple weeks ago

Just because it was updated a year ago when you bought it doesn't mean they haven't come out with updates since.

     I'm not suspecting a wiring problem either, but a schematic will show all of the components and references to locations of the components. Other than the camera, there has to be some sort of control module for this system. I have  gone through countless parts diagrams for this truck and cannot locate a control module or any sensors (radar or something) in the front grill area. Seems unlikely to me that ALL lane departure warning and forward collision alert functions are handled by the camera only.

  I have the option to either bring it to the dealership (root canals are faster and less painful) and be charged $100 -$125 /hour plus parts. The camera alone is over $400.00 plus car rental for each day that they have it. With a schematic, I have a high level of confidence that between myself and 9 other guys that I work with in an electrical engineering department here at work -we can tackle this -only if we had drawings to work with. I'm about to just purchase a set of repair manuals just to get the schematic. Paying the $450.00 for the repair manuals looks like an  economically sound decision vs. bringing the truck to the stealership.

Drop me a PM and I will see if I can come up with what you need.

I also out of the blue got a "service front camera" message and all functions associated are disabled. (collision alert, lane assist) I don't want to pay $400 for the camera myself either and what if that's not even the problem. Did anyone find any solutions or things to check before biting the bullet?

Bringing this back up, as I have the same problem in my 2018.  Taking it in this week, as it's still covered under factory warranty.  My service guy did say that he has seen non-GM aftermarket windshields cause an issue, although my truck is completely as it came from the factory - so not the problem here.  

 

However, I noticed today that a bird has apparently tried to build a nest behind my grill and in front of the radiator on passenger lower side.  I cleaned all that out, haven't checked to see if that corrected it yet, but there is some kind of sensor mounted low behind the grill on that side.  I too would like to know where and what the components of the system are.

My problem turned out to be a bad haptic seat motor. Go figure.

Closest that I've gotten to that, is my RED Light HUD flasher going off with NO ONE in front of me for well over a 1/4 mile.

Anybody got a part number for the front camera?  Dealership said front camera was indeed bad, but on backorder.  Been waiting for almost two months....  Wanna call some other dealers or look online to see if they really are on backorder before I complain.

      Missing thrust bearing? And oil selection

      By KARNUT · Posted

      I find it amusing the OP doesn’t realize this threads heading includes several engines. He should have posted in the off topic section if he wanted a more narrow focus. I really appreciate and find amusing that he actually pointed out one of my many vehicles. The Odyssey. That happens to use 0-20 oil. I love pushing his buttons.

      Missing thrust bearing? And oil selection

      Maybe, but it seems he is the only one that has backed up data to prove what he is stating. I think he is doing this more because he enjoys it and wants to get the information out to us. He's got the knowledge and access to the proper equipment and having the funds doesn't hurt.  I would love to do what he is doing and would do it if and when I hit the Powerball.  I'm not a Tribologist by any means but love to learn what I can.   I would bet there would be doubting people out there if a completely independent lab with high quality work and highly respected in the automotive industry, put out information like this.  The world can't be pleased, one just has to take the information that they are given, do more of their own research to find actual lab data to back up what they are trying to figure/find out.  Most don't bother, they just want to believe what they first see.     I don't have the minimax but my 6.2 in my 2019 Silverado with 64k miles shows excellent UOA results with 0w-20 and for my own purposes 5w-20.  Since not much of a change using 5w. I liked the data sheet information on the SS 5w-20 and figured I would give it a try.  Still the same viscosity at 100℃.   In the end we all just do what makes us happy, life is too short to get upset over trivial social media.   On a side note, I do feel GM has dropped the ball and just cares about the bottom dollar and not quality anymore.  "Like a Rock" has been long gone.  Seems "Built Ford Tough" has as well.

      2026 sierra bad brake controller

      By flattop · Posted

      Hello, my 3 month old Sierra Elevation wont recognize a trailer with electric brakes? All the lights work correctly, but no power to the brakes?   This is the factory installed brake controller. If you manually push the knob, the display shows the power % but does not light up like my 2022 silverado.   I have an appointment with the dealer, but was checking to see if anyone else has seen this issue.    Thanks,

      Post your latest oil change.

      Been using SS 0w-20 from new, but wanted to change to the 5w-20 because I liked the data on the data sheet, to me it seems like a little better product. But as you can see, not much difference. This is also with running a mix of 10 gallons E85 to a tank topped with 93. It isn't a flex fuel vehicle so any higher I get a CEL for running lean on both banks. Yes my mileage takes a hit. Instead of 20 mpg I normally get on trips I get 17mpg. This is also using EaO17 filter.  What is amazing is I have the AMSOIL cone filter on it since I have the GM Performance intake installed and that air filter has 44k miles on it.  I just take it out and shop vac it off once a year.  I use the upholstery tool on my shop vac.  Works well.
