Problems I have encountered to date include:

 

1. Radio volume does not go very high. Dealer says no fix.

2. Cruise control won't hold on a grade. I get a flucuation of 10-15 km Dealer can't find a problem

3. 4 wheel drive short radius turns are almost impossible. Dealer says that's normal

4. Factory undercoating remains soft and sticky. 3rd party undercoater says its crap and sprayed a firmer solution over it.

5. No air from the inside passenger vent. Dealer fixed it.

6. Can't get 2015 full length running boards because of DEF tank.

1 - Not to be rude but do you have a hearing issue or are you an older gentleman? These radios make me deaf.

 

2 - Cruise control should downshift on a grade and help hold speed down grades, via the cruise control grade braking. My 2012 does it no problem. If you are worried, try tow/haul mode down a hill and see what that does.

 

3 - Are you using 4x4 on dry pavement? Or is it off-road you are experiencing this issue?

 

4 - Normal. The wax they use now is currently being phased out.

 

6 - GM offers cab length running boards for Duramax equipped trucks. Are you seeking a full wheel to wheel board aftermarket?

I just got my 2015 and have no issues with radio, it blasts. You think this thing got a short turn radius you should have tried my Dodge 4x4.

It took a block to get it turned around. Sorry but mine also has a full length running board also! Can't comment on CC haven't used it much.

      2027 GMC Sierra: Official Discussion

      By Jsdirt · Posted

      I was around and remember that era very well, so I'm calling b/s on that statement. If they were that bad no police department or taxi company would've bought a single one ... but they were used in both services (and fire) for DECADES. They were bulletproof and proven. Even the early 21st century ones weren't too bad! The early models were legendary.   Mine is proof, but people like atlas are blinded by agenda and refuse to believe facts right before their very eyes.   Even decades after they were built, a new generation started driving them, posting all their builds and shenanigans on Grandmarq.net and Crownvic.net. The failures would show up then, since they all were deep past 100k-150k miles by that point, and younger drivers tend to be a little aggressive, especially with vehicles than can lay a one-tire fire for as long as you hold your foot in it. They've more than proven themselves over the decades.   The only thing that'll really take them out is road salt. The bodies and sheet metal were garbage. A victim of the cheapout FoMoCo and GM have been partaking in before then, and since.   Today it's the stuff that counts - the undercarriage that rots away first!    GMs Caprice was no slouch either. Reliable as a stone ax - the opposite of what they build now.

      Let me know how your vehicles do in 10 years. You don't know ******, kid. 😂    There's a reason that Panther platform was used as police, fire, and taxi service for DECADES ... long before you were born, apparently.

      Disconnecting Battery

      By davester · Posted

      If your connector also has a big lever to get the connector on and off, you don't want to force the lever either way, as it becomes a bigger problem if you bust the lever or the mechanism it works.

      Disconnecting Battery

      By davester · Posted

      It's just useful to disconnect the battery to prevent odd shorting out when unplugging/plugging stuff together.  I also  touch the two cable ends together (after disonnecting) to drain the small amount of stored battery energy in various modules.   I believe the main system where you need to be more concerned with, so you need to do the above and then wait some time, iss when you are working on the air bag system, to prevent inadvertent firing of the air bags.   The in-cab switches are just that, plain switches, it's generally not a problem to swap them in/out.  For my '12, I'll get an error message on the dash if I power up the truck w them unplugged, but that's it (power up= turn the ignition on).   The ITBC located above the spare tire is a computer that manages the trailer brake system.  That is probably more important to have the battery disconnected.  It does have to be programmed to the truck, either before or after it's installed, for it to work.  For my '12, I had a very hard time reinstalling the main connector to it (IDK if yours is the same or not), it turned out the silicon seal was jamming up, preventing it from going on all the way.  I finally got it fully installed by lubing the seal with a bit of dielectric grease, then it slid on and latched in place easily.

      Remote Start Noise 2024 2500 HD Gas

      By BCGM · Posted

      JR ! I just got the truck back from the Dealership today . The technician did a cold remote start on the truck this morning and it made the noise . It was determined that it was a starter issue and replaced it under warranty . Of course   it did not make the sound after a new starter was put in because the truck was not cold . We will we see what happens tomorrow morning when I start the truck cold  . Keep tuned !   Oh I found a video on YouTube of a cold start and it did the same thing your truck and mine do , I will see if I can find it and post it up
