Ok so I have tried everything listed so far air on or off vent open closed. Stereo on and off. All driving modes and  nothing stops the noise windows up down. Tape over the microphones! I can replicate it regularly now which is good.

 

The dealer has had me waiting for a call for weeks. I went in talked to the manger. He said to tell you the truth it could be one month or a year before they figure it out !!! Unexceptable answer. I leaned over and calmly said I got over 80k sitting out there and she whistles at me when I drive it! Your going to need to come up with a better answer! He comes back five minutes later and says the shop foreman will try and drill a hole in the valve covers new PCV set up. They believe it’s the whistle problem. So I scheduled it. The next day he calls me and says GM found the problem. A new valve cover is being shipped out!! Ok so yesterday they put it on instead of drilling a hole in mine.  

 

It still whistles !!! WTF GM

 

Iam about to go on a four hour trip for Christmas. Dont really even want to take the truck this sucks. 

 

So when I return form vacation.  The service manger and the shop foreman have agreed to go  for a long ride till some one crawls around and finds it. I will say thier customer service has been very helpful and they are trying. I will not take no wait till we figure it out for an answer!! I would andvise any one  going thro this to do the same with their local dealer. I will Let you all know when I schedule the ride next week.

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.

I am not sure if this is the same but I just picked up my Trail Boss. No noise when test driving but the next day in the morning. I noticed it from the left side of the dash towards the 4x4 controls b

Update the dealer just called me they found the problem late last night. It’s a emissions valve!! GM aperantly knows about it and had not told the local dealers yet. They have ordered the replacement

Not all the 2019 trucks are doing this correct?   Most you guys have a quiet ride? 

Sure hope so, quite a few people on this bandwagon :(

Thank you for this post, I was the one who asked about taping over the microphone(s) because a few of the folks were pretty sure it was ANC causing the noise. You were the only person who said that you did it with no change. This is good to know for others (me too) because it shows it’s not the ANC. My GF wants to upgrade, she loves my 2018 but is looking at the 2019. I have given her my thoughts about buying a first run (any vehicle) and to just wait a bit. So again, thank you and I hope they get you squared away soon ?.

First run new models will always have a few bugs.. Dealers have to rely on engineering to sort out some of them..
Not many engineers work at dealerships..

New unknown problems might take more time than anyone likes..
Rant if it makes you feel better.

So my 2019 sierra has this high pitch squeal as well.  Most prominent at 20-30mph while accelerator lightly depressed.  My dealer has replaced the muffler and did not resolve the issue.  Hopefully a solution from GM will come soon.  Thanks

Sounds like the GM I know.....and as a owner of a first year 2014 sadly you may have to get used  to some stuff or plan on spending days at a dealer or leave your truck with them and gamble on it's condition when you get it back.

Professional grade my azzz........

I took my truck to the dealer yesterday. The foreman and I took a cruise replicated  the noise. If I drive for a few minutes and shut the truck off, we can hear a faint whistle from the fuel tank. They kept the truck and have good direction to go. He believes it’s a pressure balance issue with the fuel tank. Their customer service has been fantastic at my local dealer!!! I will let you all know if they find a solution today!!

Update the dealer just called me they found the problem late last night. It’s a emissions valve!! GM aperantly knows about it and had not told the local dealers yet. They have ordered the replacement part it will be here Monday morning!! I will let you all know if this really fixes the problem next week when I pick it up

That's good news, yea let us know if actually solves the issue after you pick it up.  On mine, the GM folks had advised to replace the muffler which didn't solve the issue.  Thanks!

I have this issue as well. Occurs at most any speed above 40mph. If I accelerate or decelerate it goes away. It’s not the ANC. It is more noticeable if the windows are down and I’m driving down a small road with buildings. The reverb really makes it obvious. Radio on or off, blue tooth on or off, tape over speakers or not, it just does it all the time. Dealership couldn’t find an issue last week, but kept it all day and admitted they could hear the noise. They had no idea what the issue was at that time. Hope the emissions cable turns out to be the fix so I can tell my dealer. If not this might be the first and last GMC I own and the shortest time I own a vehicle. My 5 hour one way Christmas trip nearly made me go insane.

      Gas fill door

      By newdude · Posted

      Common failure.  You need to replace the fuel door housing.   The painted cover transfers over to the new housing.  To remove the old one there is 4 spots where you poke the plastic to release it.

      Gasser Subforum Has Been Quiet - - So, Regenerative Braking and Using L10

      By newdude · Posted

      No such thing as regenerative braking on a pure ICE vehicle.     Regenerative braking is the re-capture of energy from electric motors and stores it in the battery pack.  So hybrids, PHEV and EVs have regenerative braking.     What you are seeing is the charging system changing modes is all.  Its likely entering charge mode for some sort of reason is all.  All of the charging modes will be listed below.   As for L10 vs D.  L10 turns off automatic grade braking.  L10 puts you in control of grade downshifts where in D it will automatically do it based on brake pedal position and other factors.  Otherwise L10 and D drive exactly the same aside from that one aspect.    Battery Sulfation Mode The BCM will enter this mode when the interpreted Generator output voltage is less than 13.2 V for 45 minutes. When this condition exists the BCM will enter Charge Mode for 2–3 minutes. The BCM will then determine which mode to enter depending on voltage requirements.   Charge Mode The BCM will enter Charge Mode when ever one of the following conditions are met:   Windshield wipers are ON for more than 3 s. Climate Control Voltage Boost Mode Request is true, as sensed by the HVAC control module via serial data. High speed cooling fan, rear defogger, and HVAC high speed blower operation can cause the BCM to enter the Charge Mode. The estimated battery temperature is less than 0°C (32°F). Battery State of Charge is less than 80%. Vehicle speed is greater than 145 km/h (90 mph) A current sensor malfunction exists. System voltage is determined to be below 12.56 V When any one of these conditions is met, the system will set targeted generator output voltage to a charging voltage between 13.9–15.5 V, depending on the battery state of charge and estimated battery temperature.   Fuel Economy Mode The BCM will enter Fuel Economy Mode when the estimated battery temperature is at least 0°C (32°F) but less than or equal to 80°C (176°F), the calculated battery current is less than 15 A and greater than −8 A, and the battery state-of-charge is greater than or equal to 80%. Its targeted generator output voltage is the open circuit voltage of the battery and can be between 12.5–13.1 V. When fuel economy mode is active, the generator is not charging, only maintaining open circuit battery voltage. The BCM will exit this mode and enter Charge Mode when any of the conditions described above are present.   Headlamp Mode The BCM will enter Headlamp Mode when ever the head lamps are ON (high or low beams). Voltage will be regulated between 13.9–14.5 V.   Start Up Mode When the engine is started the BCM sets a targeted generator output voltage of 14.5 V for 30 s.   Tow/Haul Mode (if applicable) Pressing the Tow/Haul Mode button located on the center stack, the vehicle system voltage is raised and the remote (non-vehicle) battery will be charged. Having the headlamps on will raise the system voltage and if the Tow/Haul button is applied it will not serve any purpose. The voltage is regulated between 13.9-14.5 V.

      Hello from Australia Just sharing that there is now a way to delete the active shutters entirely with just a plug in module. Opens up tons of room to light bars etc.

      Gasser Subforum Has Been Quiet - - So, Regenerative Braking and Using L10

      By jake111 · Posted

      I have an observation and a question... 1) I watch the voltage closely because I have had to dial in the cut-in/cut-out voltages of the battery separator to my camper.  The "smart" charging drives me nuts.  Anyway, I noticed that when coasting for a while, and especially if lightly using the brakes (though not necessary), the voltage goes up from mid/high-13 volts to mid/high-14 volts.  Then it drops back down after stopping or going again.  Consistently!   The only explanation I can come up with is REGENERATIVE BRAKING!  Well, maybe that's a little bit of an exaggeration, but it's certainly free extra battery charging.   2) Driving on mountain roads I will use L and vary the max gear.  Things straighten out and I end up in L10.  Sometimes I leave it there for a while.  Is there any difference between L10 and D?
