High frequency noise coming from dash when in 4WD

They don't care, put simply. It isn't causing a "safety" issue, so they won't fix it. Brand new 2016's still have this same issue. It really seems like it should be an easy fix, but it's kind of like the ignition switch problem, they know it exists, but why fix it, because their cushy union jobs will be safe either way. No incentive to work any harder or fix a problem. Occasionally a GM rep will come on here and try to attenuate the situation by offering to set you up with an appointment at your dealer, but what is your dealer going to do. I would never buy another GM product again. Looking forward to the winter time when I get to listen to the bird chip in my car all winter again... it's wonderful

Speaking of the GM reps on here, I haven't seen them here in a long time. Maybe they're just not posting on the threads I'm following.

To me it seems like it is coming from the switch and not the TCCM? am I crazy? I tried covering my TCCM with some dampening material but I can still hear it come from the switch

I don't see how a switch could generate that noise, likely it is the module, but it may sound like it's coming from the switch. We did get to see that they acknowledged the problem at one point, but the solution was to put sound deadening material around the module. The real fix is to replace the module with one that doesn't have an electrical design flaw, but we will never see that happen unless it causes 50 people's trucks to crash

If they don't fix it, I will have to demand that they pay me back the value of the 4wd system. I don't like paying for something I can't use. I think if everyone would put their foot down on the issue then gm would have to work on it. Money talks, and we, as consumers, encourage crappy product by ignoring issues.

.... Ahh what the hell. Joining my 2nd 'ridiculous issue' thread for the day. 6500 miles... Another painful experience with a $40k truck. I thought after reading the first couple pages and seeing how many pages there were total, that for sure GM would have a fix for this. Just another reason why I'll never buy a GM vehicle again.

Just Picked up my brand new 2015 Sierra SLT 4X4 this week and the next day had a huge snowfall, as soon as I put it in 4/auto I have been hearing the same high pitched intermittent chirp as everyone else has mentioned, other then that this truck is by far the quietest I have ever owned so its really makes this noise that much more noticeable.

 

Will definitely mention it to my dealer next time I bring the truck in but from the sounds of it there has been no luck in getting a proper replacement so far....

Test drove a new f150 lariat and it didn't have any negatives to using auto 4wd. Trading in and picking it up tomorrow.

I wish I could do the same without taking a large trade in loss.

I'm lucky because I got a good deal on my truck in the first place. I ended up getting more for it than I paid when I traded it in, on top of that I got over $10k off the sticker and 0% financing. I seriously love this lariat. Shifts so smooth you can't feel itm the 5.0 has great power and fuel economy. The cabin space massive and push button start is a plus. Not to mention all the other features it has that my gm didn't.

Mine does it too. Just noticed it for the first time today when I was researching my drivetrain/diff hum... I love this truck so much - all these issues is so disappointing (and pathetic considering the cost of these trucks).

I really will never understand why GM doesn't stand behind their product.

This song and dance is so ridiculous.

 

I just got that on why my transmission delays and stumbles on finding a gear. Oh it's just these new 6-speed transmissions and all the gears. I hung up I was so frustrated.

      This is interesting. My quote tagged here is different from my original quote. After I’m driving them longer. That isn’t me. I don’t talk that way. I definitely wouldn’t express myself that way. Interesting.

      What have you done to your K2 today?

      By UrbanRage · Posted

      I have the same running boards on my truck and I do agree they are bulky. I also find myself stepping over them when getting in and out of the truck. Besides providing protection to the rocker panels, they aren't very useful.  I will be replacing them soon with the Amp Powersteps.

      OCI, not when but why?

      By Grumpy Bear · Posted

      10 Ford and Chevy engines proven to reach 300,000 miles   You may note a common 3K OCI on this list of gas motors. I skipped over the diesels. Dh'O.

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

      By jake111 · Posted

      Thanks newdude!  By the time manual selection is needed, I'm probably too much of a control-freak to depend on the transmission sensing braking to activate automatic downshifting.  I would be anticipating the situation and already be manually downshifting.   This truck replaced a 2004.5 LLY diesel with the Allison 5-speed.  Putting it in T/H made noticeable differences (when the torque converter locked, upshift points, downshift behavior).  On this 2024 gasser with the 10L1000 I haven't been able to detect much, if any, difference.  Ok, I can never tell now when the torque converter locks up.  But I also don't notice differences in shifting.  For downhills, I've probably already manually downshifted by then anyway.  Since it's also more awkward (than the 2004.5) to engage/disengage I don't even bother.  Or maybe it doesn't really matter with just a 3k lb. camper in the bed?   Thanks also for the list of reasons the charging system might select various voltages.  However, what I am seeing doesn't fall into any of those categories.  It very definitely, and very consistently, rises after coasting/braking.  Maybe not immediately, but not very long after coasting/braking.  Very consistently drops voltage when no longer coasting/braking.  It might also be interacting with the camper battery charging (I might disconnect the camper and see if it changes the charging behavior).  I also need to recheck turning on headlights for when I want to force it to charge the camper.   Another JR, in June I converted the camper to LiFePO4.  Since it's not a good idea to try to charge lithiums directly using truck, I installed a Victron Orion XS DC-DC charger (which BTW is AMAZING!!).  Being cheap, I only had to buy that one item (besides the battery, of course) to do the conversion.  The camper OEM 120v battery charger (only 19 years old and works perfectly) and the truck feed the input to the DC-DC charger (not at the same time).  But I didn't want the camper charger feeding back to the truck so I kept the old separator.  I considered replacing the separator with a 30amp diode but that means more work and might add another 1/2 volt drop.  One thing that surprised me was the voltage drop over the long 10awg wire run, so I can only charge smoothly at 8 amps (because the DC-DC charger is completely configurable).  Another reason I don't want an added voltage drop with the diode.  I might also be a little lazy but all this work is being done under the sink with a small cabinet opening.
