I'd print out the TSB posted above and show it to them and ask why this is not covered under warranty? I had my fluid exchange done and covered under powertrain warranty last year. Although mine was having the rumble strip feeling / vibration, but right in the TSB is says diagnosis beyond customer complaint is not required. And all 2018's fall within the production dates. The last page even has a section on how the labor times for being done under Powertrain coverage. Are you positive you have the 8 speed and not the 6 speed? The TSB only applies to the 8.

Curious how you even noticed the nut was missing? Being up in the cross member like that, seems like you would have to be specifically looking for it to even notice?

Interesting... good to know, it just sounds so not normal, but I guess we'll just add that to the other not normal noises these things make.

The fuel pump ticking is definitely normal, but what he's describing sounds a lot like mine which I have never been able to identify, (not the high pressure full pump or the vaccum pump) although it's hard to get a sense of a sound based off a written description. Mine has this same type of sound and when your crawl underneath it's coming from the bell housing area right in front of the transmission pan. Very rhythmical, like something spinning and hitting each time. Been happening for quite a while now so thinking it's normal, or hope so at least. Mines is a 6.2 with just 55k miles.

On my 2017 I went with 275/60/20 BFG KO2's and a 1/2 inch level and while looks are very subjective gives it the perfect stance. I also trimmed the lower air dam in the front which gave it the appearance of being at bit higher and couple more inches of front-end ground clearance. The GM performance exhaust helps finish it off with just the look and sound I was set on. I'll try to find some decent pics to post.

Or just start taking bolts out one by one until oil starts coming out.

The one from Boost Auto claims to have a triple coil for increased charging zone, not sure if that's a gimick or not but also curious for any comments or from those who have used either of these as upgrades. Price on all of them is pretty much the same. Who would have thought 2017 technology is outdated already.

Interesting... I wonder if the aftermarket one in my original post would be any better, than the ones mentioned above which appear to be a direct OEM replacement.

Only regret is the premium fuel cost

Recently got a new phone (iphone 11) and tried the wireless charger on the console only to find out it didn't work. After doing some reading and researching, including searching on this site, I quickly found that this is common for what seems to be for models prior to 2018. It does appear that replacement is fairly straightforward and found this (2014-2019 GM Wireless Phone Charging Kit for GM Trucks (Silverado & Si – Boost Auto Parts) as an aftermarket upgrade. Curious if anyone has used this or have any other recommendations on what to replace it with?

You mean somethign like this? Found this a while back when checking my cabin filter. Not saying this is whats causing your issue but never a bad thing to check at each oil change just to make sure there's no critters trying to get free rent. My truck is kept in the attached garage all the time so this can happen even when you think it maybe very unlikely. never hurts to check it every so often.

Does it sound sort of like this? If so I know exactly what it is.

Sad thing is the salt will probubaly rust the rockers and rest of the body out while the orange paint will keep the underside looking new.

Thought about that but wasn't sure if that would be good for plastics, bushings, gaskets, etc.. Unless I was just cautious with where it was sprayed and didn't get carried away with it.

So this is a mystery... Somehow somewhere I must have ran over some paint, thinking possibly a spray paint can based on the volume and splatter pattern. Unfortunately it's bright orange and looks horrible from underneath. Good thing is it's entirely underneath and didn't get on the paint, wheels or steps. Just a dot or two on the tire but other than that not visible unless you look underneath. Now the question is how in the world do you go about cleaning this up? It's all over the transmission pan, heat shield, ,Transfer case, driveshaft... Tried rubbing it with paint thinner and various cleaners, goo gone, etc.. but nothing is working. The frame, sway bar and anything black I can paint over with some black spray paint, but everything else I have no idea, or maybe just leave it since it's purely cosmetic? Just glad it's not visible unless you look underneath.

Looks like something has been rubbing on the side down at the bottom? Hard to tell from the picture angle, maybe it's the cable but from looking at the other pictures it seems like it could be tailgate?

Was thinking about replacing the tow hooks with shackles just to change things up and give it a different look. Anyone done this? I found the Rough Country has a conversion kit and was curious if anyone has done this or have experience with the RC kit? If so any pics would be appreciated. Any reasons this wouldn't be as strong / reliable as the factory hooks?

Did you ever get this diagnosed or determine what it is? Mine has almsot the exact same sound as the video you posted, sounds like it's coming from the bell housing or just infront of the transmission pan. Hoping it's nothing to be concerned about?

How important is using distilled water? I was thinking of doing a flush using the garden hose method then using pre-mixed 50/50 coolant, but we have terribly hard tap water. How much does the block hold? Is the 5 year 100k intervals still what's recommended?

So when you have the brake fluid flush from the dealer does that flush the entire system including the calipars and ABS module? I just had this done but never really thought about it until now what that really included?

Heavy wheels or tires will make them wear considerable faster too. seems like most of the ones I've seen go out are with someone who has heavy LT tires.

Actually Disregard - I was going to comment on a hand held tuner but just realized tuning isn't available yet on the 2019 + For what it's worth I have the diablo tuner on my 2017 and have the idle RPM set at +100 for same reasons you mention and is perfect now. Sorry couldn't be of more help.

Unless you have the 6.2 which does recommend premium fuel.

Anyone ever take the rear liners out to wash any salt/dirt or crud that may build where a power washer or hose can't get to? Was thinking about doing this recently but curious if anyone else had done this or feels there's any benefit. Thinking in terms of keeping clean to avoid any places for rust to start down the road. They look fairly straight forward to pull out but not sure it's worth the effort?

Borla Touring? This is the quietest of the Borla mufflers and is what what comes on the performance Exhaust (at least on the 2014 - 2018) and I have on mine. To me this is perfect, has a nice sound and tone like it should but not overly obnoxious at all even on cold start ups. You can not hear it at all at highway speeds, no drone, but you can definitely tell it's there when you get on it. Combine that with the dual side exit polished tips, what's not to like about it Other than the price. Next step up would be the S-Type if you want a little more sound. Attak is the loudest which is too loud for me.
