Update - Issue still exists. I have given up.

So I believe I have solved this issue. It turns out that my dash cam was causing this, I had unplugged my dashcam before, but never disconnected the fuse taps from the source. For reference I used the following fuses in the passenger side fuse box: F58 - 15A - Info2 - Constant F20 - 15A - Cool Seat - Switched After digging through the wiring Diagrams and All-Data, Info 2 is related to A11 Radio Module. For whatever reason the A11 Radio Module communicates with the Front View Camera / Lane Departure system but indirectly based on the communications wiring diagram. Disconnecting the dash cam caused the camera and lane departure to function as designed. I now have the dash cam connected to F5 and F43 and I have not experience the same issues. Not sure if this was fluke, but boy I can't imagine why this would have caused any issues, other then potentially bringing the system voltage below a specified threshold.

Thank you for your reply. No fogging up, nothing obstructing the camera's view. The dealership ended up replacing the camera yesterday and within 10 minutes of driving, the system ended up doing the same thing. However the dealership could not replicate the issue.

Hello wonderful forum folks. I have a 2022 GMC Sierra 2500 HD AT4 with 38,000 Miles (just outside of bumper to bumper). Dumb me, I have had this issue for awhile and haven't brough the truck in, so now it's on me to correct. I brought the truck in yesterday and explained the situation. When I first start up the truck, the Green Automatic High Beam rediness light on the dash turns on, and for the first mile or so of my drive if the conditions call for it, the auto highbeams will function normally. After this mile or, usually less then 5 minutes of driving, regardless of road conditions, that green light will go out, along with the lane departure warning readiness light, and will not come back on. If I push the button at the end of stalk to active the auto highbeams, it does nothing. If I push the LDW button on the center stack, I get the message that "Lane Departure Warning is Unavailable". This problem will continue for the duration of the drive, regardless of if the road marking are freshly painted with new reflectors or old. The odd thing is during the day, and even during the rain when I can't see the road markings, lane departure will never fail. As a proof of issue, last night I recorded the dash and road conditions, until everything failed, and then I restarted the truck and drove the same roads and they worked fine, for the same period of time, and then died out again. Has anyone else expireinced this issue? Is there a GM Tech, that could send me the programming / calibration instructions for Auto High Beam / LDW? Wondering if this is something I can fix on my own. Youtube 1: 2:29 Where System Fails. Youtube 2: 2:46 in and the system fails again.

Curious if anyone has attempted this? Hate to revise a dead thread, but after 2 years there may have been some movement.

Great thread, I have done this as well as the "Poor Mans Camera" and can say everything worked out great, I did order 48" cables and I did not have to trim my bed liner at all. Thanks all!

Great thread, I have done this for my 2022 AT4 HD, and can say everything works great, worst part will be running the cable from the back through the gooseneck on my old trailer

My 2022 AT4 HD has them on all four doors.

Another point to this, I have a 22 Duramax, I do all my own maintenance. I buy oil from Costco. It is $38 for the oil and about $14 for the filter. Easy and cheap. The dealership would charge closer to $150 for the oil change on my truck in SoCal. A Fuel filter can be had on amazon for $27 and takes about 15 minutes to change. The dealership charged a buddy of mine $300 to do his fuel filter. All depends on where you go and what you are willing to do yourself.

Just as a help to everyone doing this This is a writeup on this forum for creating your own accessory camera for a lot less money, I personnally have not done this yet, but wanted to share with the rest of you in case you haven't seen it.

How do the Bilsteins compare to the Rancho shocks on the AT4s and Denalis? When hitting bumps with our 5th Wheel on the freeway it can be really jarring, curious is upgrading to Bilsteins would help the issue?

That looks like a great system. I am just trying to use the onboard tools to keep another piece of technology off my dash, and work towards a factory approach.

Thank you! I have been scouring and couldn't find anything... Can you confirm these work?

Reviving this old thread, is there an aftermarket more cost effective solution to the GM Trailer TPMS #86803857 package for the 2022 Sierra? I need four and think the $150 per pair is a bit ridiculous.

I too have insane brake squeal issues, my dealership told me it was normal. I don't think so, not on an $80k truck.
