  1. My 2016 has done it from day one. No biggie, just noticeable.
  2. I got rid of my 2013 Avalanche just because of this issue!! Took a huge loss! How can GM help me now??!!
  3. No. Windows up or down, sunroof open or closed, it sounded like the radio was on playing music very low. It was VERY hard to pinpoint for me but I adjusted the hood latch and lowered the hood a hair and it was gone. Only did it at certain speeds
  4. I had the same noise, turns out the hood latch needed adjusted. Air was getting under the hood just enough to whistle. Once adjusted, no more whistle.
  5. I thought the same thing but I wouldn't
  6. GM truck sales are down 9% compared to this time last year. 1st quarter sales.
  7. Mines off since it cracked in the snow
  8. My 2016 2500 is the same way, bare metal and rusted. Built in August 2016.
  9. Well, I'm going to answer my own question, lol. Dealer called and said GM just put out a bulletin and it states that the noise is from the internal transmission solenoids being commanded to minimum line pressure by the TCM. Noise is considered normal. Naturally. Just about every GM vehicle is affected from 2006 to 2019. They gave me a copy of the bulletin. Document ID : 5246136 #PIP4021D: High pitch whine or buzz heard from under the vehicle, dated 2-21-19.
  10. I cracked mine in the snow also. It's now in the trash. I'm not paying $200 for a new one. Looks better without it anyway.
  11. That's exactly what I did. Silicone sealer around the XM antenna. When it sat with 4 inches of snow and ice on the roof, a few drops came thru. Dealer said he will replace the XM antenna gasket, no problem. I just didn't want the service dept to drop the headliner. Since I sealed it about three months ago nothing has came thru, knock on wood. Had more snow and ice on it and took it thru multiple car washes and nothing.

  13. If anyone can help, I'd sure appreciate it. 2016 2500 6.0 gas. Sometimes, (not always) when after shutting off my truck, it gives off a high pitched whistling noise. Sounds like a tea kettle boiling. Not constant, off and on. It starts about 10 or 15 minutes after shut off. Not always, just occasionally. Coming from under hood but I can't pinpoint it. Dealer says it's some electrical items shutting down. I'm sceptical on that as it doesn't do it every time. Sounds like the truck is sending morse code in a boiling tea kettle sound, lol. Anyone else heard this noise? Thanks Gary D.
