Sure...but there is no "update" to be had. GM has not issued any support for this.

No. Why would it "go away"? There is a button to disable it though still. On the driver's side of the dash now.

"I see around town" That's a small dot in the total picture. They are popular in YOUR town. They aren't popular where it counts. Sales data.

It is not supported on the trucks. Period.

The one you posted is correct. Just the 4 bolts are one time use. The other two don't need to be replaced.

No. If they were rammed in with an impact, they are stretched and need to be replaced. Hence one time use torque to yield fasteners.

In case you don't read these until later today... PPE makes me "think" that you have a 3.0 Duramax. Which you'd want quantity 4 of the 85628208 seal and NOT the 85628205. IF you have a gas truck 10 speed, you need one of the 85628205.

4 vertical bolts. They are one time use torque to yield fasteners and should not be re-used. Yes, they should be torqued to the proper spec.

Is this supposed to be in English? "close to 100 fake, new brake pads sign on the dash board" Pull the wheels off. Check the brake pad thickness. Check the sensors out. You could have good pads and the sensors aren't in to the worn out position, but have an electrical fault with the sensor or the plug wiring to the sensor.

Gas or diesel??????????? You did not indicate. Your topic just says "2022 10L80".

That is a huge misconception. Bigger does not always equal safer. Modifying does not make it safer either, with exceptions. Think of this. Your truck in stock form is capable of emergency maneuvers, proper stopping distances, its handling is designed around the factory wheel/tire packages, etc. 37s and a lift? Now you've affected your braking distances, handling and ride control. You've raised your center of gravity higher. Your front visibility is now obstructed more than stock, same for your rear. Does it look cooler? Yes. Does it now work as good as it did from factory on road? NO. As for my mention of exceptions? Say you had a sedan or crossover. They typically come with all season tires. If you swap out for a performance all season or a summer tire, you improve your car by lowering its stopping distance (better braking because of traction) and improve the handling (regular and emergency) of the vehicle. That is an actually improving modification. My old 2019 LD 1500, I ran UHP all season tires on 20in wheels in a factory offered size. It improved all aspects of how it drove over the Duratracs it came with from the factory in the stock 18" tire.

Is it though? Like LTZ, not a high take rate. Current Sierra has AT4, Denali and Elevation as its main bread winners. Each trim accounting for 25-35% of sales for Sierra. SLT makes up about 10-15% at best. Like others have predicted here for GMC, it will be: - Pro (equal to WT Chevy) - Elevation (replaces SLE and SLT) - AT4 (and X) - Denali (and Ultimate).

There are knowns and unknowns. Knowns: - LT, RST and LTZ names/trims are gone. The new "Silverado" trim level replaces all 3 of those. You should be able to configure the Silverado trim to match the equipment levels of those three trims. Unknowns: - Custom. No mention of what engines it will have access to. Dual exhaust being standard does seem to confirm a V8 option for the Custom trim though. My "guess" is that Custom will have access to the Turbomax and the 5.7. I could be wrong though. The current Custom trim went 2.7 Turbomax only the last 4-5 years, and only had a single side exit exhaust. - 40-20-40. I would imagine that is NOT going away. They only focused on showing the new interior on the top trims, Trail Boss, ZR2 and High Country, hence the images shown are just bucket seats up front. The info should start coming fairly quickly over the next weeks and months. Production is supposed to start up later this year, so when the order guide launches, you'll be able to see the configurations of engines, cabs, seating, etc.

Boy do they have some margins in that to come down $5000!!!!! Does it change my thoughts? Not really. That's only one thing addressed. The transmission. Still needs an oil pump belt if that hasn't been done yet either, which per the Carfax, looks like no. I still don't like the long service intervals on the oil and the fuel filters. And then still, timing chain because 2020.

"Pre existing lifter damage" What exactly do you mean by that? You should be asking for service records. Any warranty work performed as odds are if a truck has had a lifter or lifters and camshaft replaced that is a 2022.5+up, it was likely done under warranty. These DI engines have normal ticking noises such as the fuel injectors and high pressure fuel pump, so some noises will definitely be normal. A lifter that isn't pumping hydraulically all the way will stand out as it will be an intermittent tick, not a steady one. So like "tick_______tick tick_____tick_________tick tick tick___tick____tick_" It will most likely go away too about 5-7 minutes of run time. That truck would need a lifter or lifters but not because of the deactivation lock pin failing, but because its not building oil pressure to it right away. A collapsed lifter will be very obvious. It will be snapping or popping out the intake.

There hasn't been a glovebox light for like 30 years. Do you really think they'd add one now?

- The Silverado "Silverado" makes no sense. Perhaps they should have picked another old name like "Scottsdale" or "Cheyenne"? They roll off the tongue a LOT better. "Silverado Sottsdale" or "Silverado Cheyenne". Or just bring back "LT". - Because of the "LT" drop, now Trail Boss sounds stupid. Custom Trail Boss, and then the higher version is "Trail Boss". Like...WTF. - 6.6. This was a debated topic for sure but I was camp 6.6 months ago. Made sense to me. - I want to know the power #s more than anything else at this moment. I get they are calibrating and validating, but those are probably the most important thing they've held back. Moreso than towing #s. 2.7 and 5.7 are the most interesting to me for the numbers. The 6.6 will be close to if not just over 500hp, that's a given at this point. - Looks. Definitely improved, slightly safe up front? Its a blend of Tahoe and Silverado HD. Its not full Tahoe or HD though, making it unique. Interior wise, I loved the 2022.5-2026 upgrade to Silverado but this is a nice integration of those new larger screens they are using, and it's not a direct copy of the Tahoe/Suburban. Seeing one in person or live video in the meantime will be important to get a better feel of the looks. - Biggest flaw? 4x4 switches. WHY are they UNDER the HVAC in the center stack?!?!?!?! - Biggest glow up over last gen so far to me? High Country. That two tone interior they showed is just fantastic. The new badging/font choice really classes it up as well. It's Denali levels of good for Chevrolet.

You need a better code reader/scanner. You are missing codes. Did the dealer give you a copy of the SAVI scan from that visit? If the fluid hasn't been changed, change it. Shudder will likely go away.

TLDR to my other post... Hard. Pass. Too many what ifs. Are you set on a 3.0 Duramax? Have you considered anything not GM just in case? If you don't have to have a pickup, lots of other options for $27,000 out there.

I see some red flags. - No mention in the Carfax if the oil pump belt was changed. LM2s had a 150,000mi service interval, and its got 164,245mi on it. So right out the gate it needs about $3000-3500 for that to be done before driving it another 150,000mi. Belt is at the rear of the engine. - If something happens to the transmission valve body, the special coverage is expired by mileage. That will likely be an out of pocket expense, with zero or near zero GM participation if something happened even though its in by time. - 2020 LM2s seem to need timing chains after 80,000mi at some point. They fixed this end of 2020/starting 2021 model year engines. They will usually set a P0016 I think? There is another $8000-10,000 if it needs a chain. The main chain is at the back, secondary at the front so the pump belt would be done at the same time if it needed chains. - Long oil change intervals. 7,000-8,000mi on average, probably close to 0% or perhaps to or beyond 0% on the OLM. Lots of them not at the dealer which makes me wonder how much of the oil ran through that truck was the proper Dexos D rated 0w20 oil and not just gas engine 0w20, which is not the same at all. - Long fuel filter changes, again likely taking the fuel filter life to 0% or more. First one went 28,603, second was done 43,094 miles later at 71,697, from there another 46,452mi to 118,149mi, and then the most recent one 37,026mi later at 155,175mi. So counting its original fuel filter, its had only 4 fuel filters on it. No bueno IMO. Good news? - It has had only two warranty trips to the dealer. The first free service (end of December 2020 on the Carfax), and the transmission reprogram recall (end of August 2025 on the Carfax). - Truck did a LOT of moving, so that might explain the lack of emissions related repairs like bad NOX sensors, bad exhaust temp sensors, bad glow plugs, etc. The "emissions system checked" could just be how something was flagged for Carfax. GM dealers have to do SAVI reports for warranty repair orders so they scan the truck. So its possible that is there for that?

No idea. I'd start at Crutchfield or your local car audio shop and see what they can do. If it were me, I'd have bought a bench truck to start and then have done the GM Kicker upgrade if I wanted more sound.

I dont think you will be able to. That sub is designed to fit under the full console. You'll have to go aftermarket and get a bypass harness and do an amp/sub under the rear seats.

...was looking to see what the 3 post OP had to say since they've got a personal issue here and 3 different threads they made within the same time period...just today....and then regurgitating that some owners on facebook and other forums have issues which is a small number out of total ownership of 3.0 Duramaxes.

What problems?
