Well, we are on DAY 2 of them trying to replace this stupid hose.  I still don't have my truck and now they are waiting on another part to complete the process...

I have a whine noise coming from the engine bay but it’s mostly from 60-62mphs. Weird. As soon as I hit 63 it’s gone but stays constant if I’m at 62

Mine also sounds like it's coming from the engine bay but i believe it is the same issue with the vent hose. I took mine in and the dealership ordered the new hose from the above mentioned TSB.

Well, it ended up taking the dealer 4 days to finish replacing this hose and all of the other recalled items.  BUT! the whistling noise is gone praise the lord!

Those are the only two issues I've had with my truck so far. 

 

Ask them if they want you to reproduce the noise before you leave the dealer...I had to drive back to mine and take the tech for a drive when they couldn't make the noise.

I'm hoping that by being armed with TSB numbers, that they won't give me any "could not duplicate" bull. Especially being that I'm a BMW tech and know the business inside and out.

The way this issue is being handled at the dealer and corporate levels has destroyed any confidence I have in the company.  My truck was there for 6 hrs while I waited and they said it passed diagnostics.  They removed, inspected, and then reinstalled same part.  Sound gone for a day.  Then back.  I called corporate to see if they could assist dealer and the service was atrocious. Took them twelve days to respond to my initial inquiry and when they did the response was that this is not a known issue and that the dealer needs the truck for further work up.  I explained that it would be nice to have a known issue with known fix before dropping off the truck again hoping that their second round of shenanigans would prove successful.  I work a lot so I can’t get to the dealer easily and the corporate customer service person said I had three days to drop off truck or the case would be closed.  This far the sound prevails and I imagine the case has been closed.  Add this to the fact that at delivery driver seat wasn’t poured in so lumbar didn’t work and that the panel below steering column rattles like I’m being warned to step back or else.  ::smh::  this truck purchase is certainly the biggest mistake I’ve made in the automotive realm.

Ok the whistle is gone !!!

They have resolved the issue with part #84626475 Hose 3.120 Y 

Its a vent hose on the gas tank that was to small. It collapses upon itself and whistled. 

Does this work on a 2018 L86 Silverado 6.2?

Well now...

Do you have a 2018 service bulletin for a 6.2 L86 engine -- they allege its a completely different fuel system in the 2019 and refuse to fix it.

I've been all over the water leak thread. It's quite a soap opera in there.

However, I did make a discovery today. My whistling noise is from the driver side of the truck. I let the window down, and heard it louder. I folded in the mirror and still heard it. I think maybe the Z71 emblem on the front fender could be causing it. I may put some body tape over it tomorrow before I drive home and see what happens.

It's an easy fix, new gas fill vent tube i believe, my dealer saw the TSB and ordered the part and fixed it no questions asked.

    • I have a 2015 Silverado and sometimes I can not get in to the truck. I use the key to unlock the driver door. Something is locking the truck when I unlock it, last night I left the truck open and this morning it was locked with the mirrors folded in. This happens while driving so it is now a safety issue. I reach down for the folding button and they open, then they close again.  Any advice, thank you,   Ed
    • Did you ever find a resolution to this? my 2019 Silverado 1500 is showing the exact same headlights issues with the exact same symptoms.  would help a ton if anyone has any advice on this or better yet a known solution..
    • Wawa and Meijer here have ethanol free (88 & 89) I use for my mower and lawn equipment.  Its not much more than reg.  I paid $3.29 a few weeks ago.  
    • 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.
    • 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.
