Did they replace the collision alert camera?

That is what fixed mine, the unit up in the mirror.

Yes. Didn't fix mine. They said that they can't erase the fault codes so maybe that's the reason it's not enabling the features. I'm sure they'll figure it out on Monday.

Get us service loaners, so we can have the dealership diagnose the issue if customer service is extremely important to you.

I know when they did mine it took them a long time to get it reset and properly calibrated. They had to drive it almost 50 miles to finally get it.

Good luck and I hope they get it fixed.

Interesting... They drove mine for 4 miles only... Checked in with 9202m and it left the shop with 9206. 🤔

The second time it happened was just a day after I got it back. When I pulled the fuse, I can see tool marks on the fuse spade, so it had been pulled a few times before I looked at it. And yes, it can be the fuse. If the space tolerances are off, it will briefly lose power to those devices and throw a code. By pulling the fuse and repeating, you're essentially resetting the devices and clearing the code. I have a code reader and can see there are no codes. If the camera is defective, it wouldn't work intermittently, unless it's losing power. As far as the dealership is concerned, never trust these people. I had a 2015 Jeep Wrangler Ruby that would throw a check engine code if you were on a steep incline traveling at a 65 mph and it pops into passing gear. Long story short, they replaced the heads on the jeep and did a few other things that was simply absurd. I spoke with the mechanic and asked why would he do all that work, when it's nothing more than the ECM that needs a software update. He said that Chrysler, who owned Jeepbat that time, instructed them to do work sobthat the customer would think they were at least doing something. My grandfather was a master mechanic for Ford, so these are tactics used to make the customer happy to a certain extent. Don't trust these guys, they get paid every time you bring the truck in and make money off warranties. I'm about to make another trip to San Francisco, so if something happenes, it'll happen on this trip.

It works on the 2022's refresh? 

The reason I ask is when I got my ZR2 I hooked our scanners up which work previous models doesn't communicate with it. 

We were told GM has changed everything with the refresh and hasn't started releasing it yet.

If there is something out there I would like to know.

Unfortunately, I am having the same issue with my 2022 Silverado LTZ Z71.  Amber Front Collision light is on and LKA will not turn on.  Will try the fuse option and let you know what happens.

Just left dealer and they said it was “cornea”/camera and are trying to figure out part number to replace and then order. Hope this is the fix

From the experience of others on this post, it continues to happen. At the moment, there isn't a recall for the fuse block, which is what I believe to be the issue. After tweeking the a couple of the spades on the fuse itself, I've not experiences any issues. It happened 3 times prior and one of those times was just a day out of the shop. I'm not going to allow them to replace anything until we get the missing chips. They get paid by GM every time you take it in. Doesn't matter if it fixes anything or not. Even the guy you check in with at the dealer makes commissions from it. Don't trust them at all!

Well as it turns out there was an error in the calibration the first time they did it… a different tech recalibrated it today and it works fine. 
 

Yeah yeah, I’m on my way to get gas 🤣9344E00B-6ACA-477F-B5FA-2625BB8E63E2.thumb.jpeg.d6ebc07568d603d7723fa3e921b5eb6b.jpeg

Pull it and prior to putting it back, slightly bend 2 of the 3 spades so it makes a tight fit. The metal expands with heat and contracts with cooler temps. I think this is what's causing the issue.

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Atlas · Posted

      tl; dr I've now reached the 6th floor of hell. I'm chronicling my journey for my morning readers.   Pulling the top of the intake apart was moderately easy but it involved a lot of parts, connections, and minutae. I was preparing for the new fuel lines to arrive ("nut and bolt kit" it's called). The fuel line connections are notched and held in place by the manifold and a metal plate with a T27 screw.   It's on the back of the intake, under the firewall, with little clearance, and two hard metal fuel lines in the way. I was using Franken-tools (weird combinations of 1/4 inch ratchet with/without an extension, with a bit holder for my T27) to get in there. One of my sockets and bits fell off and has yet to emerge on the floor. I lost a second setup and that's when I almost started throwing tools. But that was the point at which I had gotten traction on the Torx head, and it promptly stripped. No more traction.   I started humming "1-877-kars-4-kids" because I was about at that point. You know what? I'm $1500 into this thing and I can make it disappear just as quickly. This isn't fun anymore. I had spent a lot of time already "tidying" around the engine bay: Fixing all the "someone's been here before!" BS. The truck has been exclusively dealer- and shop- serviced and I'm reminded of why I never let other people work on my cars unless absolutely necessary.   Speaking of dealer service. This truck has a 1" stack of records going back to 1995. I put them all in an excel spreadsheet, date/mileage/description.   The CPI spider has been replaced 4 times in 85k miles. The EGR? Another 4. Multiple, multiple O2 sensors. One Cat. 4? Sets of plugs and wires, and I swear half the stack is diagnosis paperwork for "misfire, runs rough, extended crank, dies at stoplights".   GM was producing some proper crap back then. And it was still well within the era of brittle/crappy plastic. (Windows 95 was released the same month this truck was sold new, we HAD the technology!!)   There (was) a plastic shroud around the evaporator core and HVAC fan in the engine bay. I noticed a chunk of it missing so I poked at it some more and it literally shattered. Touched it some more and pieces were crumbling off. Had a good laugh. Clearly whatever plastic garbage they were using had broken down over 30 years and was literally turning to dust. That was a good half hour of using a shop vac to remove the rest of it.   Back to it.   I was going to give up for the evening but then decided I'm already level 10 pissed off at the stripped screw: G* D* it, give me my tools back -- and my JOY. We'll do this the hard way: The whole intake is coming off.   Blazer won Round II. After finally finding and accessing the 12 intake bolts and using a pry bar to unseat it from the heads, it popped loose in an explosion of gunk and grime raining down into open ports. Awesome.   6 times I reminded myself: Be careful of the temperature sender on the front of the intake.   YEAH, I forgot again and snapped it clean off in the removal. Add another $20 to the ever-growing list of new parts this thing is consuming.   The shame is, long before removing the intake, I had changed the oil in prep for Tuesday's momentous fuel line replacement that was going to be the magic fix and I'd have a running Blazer to tool around in this next weekend. The intake removal, including raining gunk, also gushed dirty coolant all over the valley. Of course it did. Welp, there goes another $35.   I now need an intake gasket set, bolt set, coolant temp sensor, another 5 quarts of oil, some RTV. Don't worry, I've already got 3 new jugs of Dexcool and a thermostat waiting. I'll fill it with clean water first to get it running, dump it, and then add the Dex later on in case... well, let's not go there. I'm only tearing this down once, next time the truck is going on Marketplace for FREE.   Oh, and I'm going to need vacuum hose for all the stupid connections placed at the rear of the engine which have since disintegrated. Come on, GM....tell me you don't do that anymore?   Oh, and the ears on the distributor where the cap screws down are both cracked. I mean, why not put a new distributor in it too. You get a distributor, YOU get a distributor, Everyone gets a new distributor!   This truck isn't out of the woods yet...I'm already questioning how much more time I'm willing to sink in.

      Bent valve in 2025 GMC Canyon Denali - Requires engine swap at 14K miles

      By William Aldrich · Posted

      NewDude, thank you for the suggestions!    I did follow up and the dealer indicates he has an open CX case and is working with DPAC (Dealer Parts Assistance Center).   Per the dealer, GM has had a quality spill and is not providing an update for when a replacement engine will be available.

      Poll: Does your truck have the rear window leak?

      By Silver Yeti · Posted

      That's interesting.   There was a factory wire-hole in the back, top of the rear cab, which had a wire for the third brakelight assembly running through it, as well as several holes (10 of them I believe) for all of the studs coming off of the 3rd brakelight assembly itself.   I sealed all of those holes with RTV/silicone as well.   I found it kind of odd, that none of those holes, were sealed with any kind of sealant by the factory - if there was any there, it wasn't very much.   That said, I've been out in heavy rain and have ran the truck through high-pressure car-washes a few times now and she has been 100% water-tight to this point.   I feel very confident in the repair, we'll see how it holds up.

      2024 Silverado 2500 HD with the 6.6 Gas (L8T) Engine

      By Jay-22-2500 · Posted

      I bought a used 2022 2500hd with 6.6L in February. In March took a 2200 mile trip towing our 6500 lb trailer. Changed the oil day before leaving and when we were arriving at our 1st destination, low oil light came on (roughly 1000 miles) it was 2 qts low. Now it towed like a dream, no issue there, and we did go through the mountains of TN, but still, 2 qts! Luckily I did purchase an extended warranty. Brought it to the dealership in April, oil change and consumption test. Brought it back last week, 1300 miles, no towing, and no oil showing on the dipstick. GM is reccomending a new engine (cheaper than them rebuilding), we'll see if the warranty company comes through.

      T3's and Ibuprofen. I do have a cryotherapy unit (ice machine) and a lift chair that will allow me to raise my legs above my heart.  There are topicals that I can use once the wound is fully healed.
