Hi All, new to the forums, I just bought a 2016 GMC Sierra 2500 HD Denali and I’m having a hard time with the 110v power outlet. Ever since I bought the truck it hasn’t worked. I removed the passenger side panel and checked fuse #35 and noticed it was blown. With the truck off and nothing plugged into the outlet I removed the fuse and the second the new 25amp made contact the fuse blew instantly, I tried it again with another 25 amp fuse and same problem. Took to the dealer and they’re wanting to charge me $600 to diagnose the problem as they have to “rip apart my whole dash” to isolate the issue. I looked inside the outlet and nothing is inside that would short it out. Before buying a plug or an inverter I wanted to ask here if there’s anything else I should try?  TIA

      After 1 month of owning my new 2019 AT4 without any issues, I had the Nav SD card not installed error. The next day, the nav system went through s long loading process. Since then, with every vehicle startup, I now have a 10-25 second process of the nav system loading before it can be used. Previously, it was always nearly instantaneous. Also, the radio will be randomly self-muted. I brought it to the dealer last week and they did an infotainment system software update claiming to have fixed the problem. Nope, it’s still taking 10-20 seconds to load navigation and the radio was muted this morning. Anyone with 2019 Sierra AT4’s or Denali’s noticing a change in navigation loading, specifically now seeing loading screens where there haven’t been before?  Is this just normal Nav function and somehow, for some reason, I just didn’t have it happen or didn’t notice it the first month? Could GMC pushed an OTA update that now cause the Nav to take longer to load?

      I installed an aftermarket billet grill on my 2014 GMC Sierra.  The horizontal segments of the grill are pretty close together.  The truck looks great but now I have wind noise.  20-40 mph I get a humming noise and then higher speeds I get more of a whistling sound of various pitches.
       
      Doing some internet hunting, I've seen suggestions of stiffening the horizontal sections by gluing on vertical supports.  I've also read about coating the back side of the grill with silicone or some other rubberized-like coating.  But I'm not sure how that would fix it.  Is it just interrupting the trailing edge of the horizontal members and that stops the noise?  Some have suggest adding a mesh  behind the grille as well.
       
      Anyone have this problem and a sure fire solution (other than getting a new grille!).
       
      Thanks!

      I decided I would make a listing of the all time best Government Motors trucks of all time. I HOPE YALL ARE AWARE THAT THIS IS JUST MY OPINION. BUT I KNOW FOR A FACT THAT THIS LIST IS DAMN NEAR PERFECT. I know this because I am a Chevrolet enthusizt. 
       
      List going from best to worst:
       
      1) T1XX-easily the best gm truck gm has ever designed. I love my rst and am thinking about a trail boss due to my love of spacer lifts. 
      2) GMT400-kinda hot tbh it’s just a lil’ uglee 
      3)K2XX-I like the Z71s and Custums
      4) Squarebody-not bad...just a lil’ too square lol
      5) gt900-so hot and reliable af. Honestly I put this above Squarebody. 
      6)trucks made in late 60s to before squarebody (idgaf what they’re called...Dey ugly tho😂😂😂)
       
      honorable mention: el Camino is May B best truck of all time in my correct opinion
