Update...

 

The second dealer also stated the noise is NOT normal. We compared to another 2500 LTZ and no noise. 
 

Called customer service again (they acted like they knew nothing about it at first...) and setup another appointment with the original dealer- now I’m dealing with the Service Director only. 
 

The service director ordered and replaced the Booster Inlet Hose # SPO 084150115 (2 days at the dealer).   When I picked the truck up there was no noise. Once it warmed up- the Groaning noise is still there and now there are also noises that sound like possible air in the lines. 

I take it back in Monday which will make 5 dealer visits for this issue.

 

If it’s not fixed this time around is this a lemon law case?  Hate to do it, but 2200 miles....

 

 

Can you give us an update having same issue with mine  not having any luck on a fix saying is normal bs if you ask me just spend 60+ to have a humming noise

Any updates on this? I have a 2020 Denali HD Duramax and am having the same issues. Had the truck in the dealership 6 times now. They’ve replaced the intermediate shaft, power steering pump and still making the same noise. Very frustrating as I absolutely love this truck, but getting a bit ridiculous

I sat in 3 different gas 2500 at the dealer that made the same noise.  2 others didn’t make the noise. GM seems either clueless on how to fix or just unwilling to repair something that’s apparently just an annoyance. 
 

so.  ...

 

I bought a tiny Flowmaster muffler and now I barely hear it.  Seriously, that’s what I did. I’m tired of wasting time on it, I really like the truck otherwise.

I have a 2022 2500hd LTZ gasser and had the same dreaded low speed (under 35mph) power steering whine since brand new.  Sounded like the noisy 1990s Ford power steering units.  First, took it back to the dealer with still under 1000 miles on it and they replaced the power steering pump. They claimed it helped but did not entirely fix the problem.  Picked it up and did not notice any improvement with the issue.  Took it back again and they worked with GM tech support and agreed to replace all the hoses.  They claimed the issue is poor and over crimped hoses causing restriction. Fixed the problem and 100% better.

Wonder if the cold weather hoses, gm sells aftermarket, would cure it?

Well..

I just traded in my 2019 1500T1 Z71 LTZ Friday for a 2020 2500 Z71 LTZ Gas.  Basically a bigger brother with a few more options.

 

On the way home from the dealer I started to hear a groaning sound from the power steering.  It has Digital Variable steering assist.   Sounds like a bad power steering pump from the ones I have heard in the past.  Sound changes with engine RPM, gets louder once warmed up and louder the farther you turn the wheel each way.  Truck has 297 miles...  :(

 

I haven't seen any complaints about this for the new model unless I missed the thread.  Anybody else?

 

My dealer has been great, providing me with a brand new Malibu loaner car, but damn I want my truck, lol!  

 

UPDATE

 

As I type this they just called me.  "Known issue, no  fix yet per GM" .  They are submitting a report or something like that.  They also admitted it shouldn't make that noise.  The Tech seemed genuinely concerned to fix it but no resolution.  I'm headed to pick it up now. It drives perfectly, just annoying to hear that all the time.

 

Hope this doesn't turn into one of "those" threads...dammit.

 

 

 

 

Well, it 2023 and my brand new Silverado gasser is doing the same as all you guys are talking about. Very disappointed with this noise in a $64k truck with 1100mi! Glad I found this thread. At least I know I’m not alone. Made my 1st appointment with the dealer. The mechanic said he’d try another pump. Here’s hoping!

Going to ask about this fix when I bring mine in! Thank you!

What Fisker said..is what my 2022 3500 gasser is doing.  Been doing this since it was new. I have 25,000 on it now and still makes the noise and didnt get any worse. I'm going to leave it alone so not to cause a "real" problem from human hands.

I like the thought of crimped or restricked hoses though, When/if mine ever leak and i replace, maybe the noise will go away lol

No idea if this will work for you, but I posted on this back in December:

 

FWIW

 

The whine was driving me nuts too and it started at about 5000 miles.
 

Dipstick read right in the middle of range. So I sucked all the oil out which was VERY DARK (while rotating the wheel all the way left and right). Then I flushed it with new oil (siphoning and refilling). Since my mechanic friend said I should add a leak additive, I added: 


Bar’s Leaks - Power Steering Repair

 

And finished with it filled to the top line of the dipstick. 
 

Happened to be taking a 300mi drive the next day. When I arrived the sound was much quieter.
 

Sounds like it did from the factory.

      Transmission Woes :-(

      By asilverblazer · Posted

      Yep, just a quick reference point.    My main point being I’d do a thousand other things before I’d pay 10k for a transmission.    Speaking in ignorance cause I don’t look at these trucks, what is it worth? 20k?

      Intermittent no-code issues on 2022.5+ V8 trucks — what did the shop fail to capture?

      By asilverblazer · Posted

      I think users are going to want to pick their monitored parameters, which parameters they want to see first.    It should probably start with baseline at a minimum and adjust to learned, but be able to overlay baseline for comparison.   A simple severity level would be able to determine what type of alerting is appropriate or user selectable.    Why not use the OBD port though?   I think a phone connection would be a good idea, push notifications type deal.   Number 1 issue is having data is useless if you don’t know what the data should be under normal conditions.

      summer road trips in the 2026 2500HD

      By Chuck FB · Posted

      I thought I would use your thread and add to it as I just did my first longer drive with my truck in the last couple of days. I drove from the Grande Prairie area of Alberta down to Edmonton and most of where I drove in the city was the ring road so fairly free flowing but a bit of stop and go as well in the city. Stayed the night and returned home and not too many stops along the way each way but every restart and certainly every cold start sets it back for fuel mileage. Why I say that is I see some people will cherry pick a fuel mileage leg after the vehicle had been warmed up driveline wise before hand and its a forgiving ( easy rolling drive leg for example ) and call that their fuel mileage which can give a false perception of reality. I was not heavily loaded at all but never the less the flip bak cover, rubber bed mat, various tools etc and extra jerry cans of fuel all way up to a few hundred pounds of dead weight so its not an empty truck. The cold inflation tire pressures are set more near the freezing point so once they are warmed up driving I was showing 45 front and over 40 rear and realize high inflation pressures would help a little in fuel mileage but certainly not the ride on our crap sections of highway. The weather was good so was not raining as that can really drag mileage down, in fact I had a bit of a tail wind on average driving home. Most people on here would never have driven on that freeway to visualize it but its got a fair bit of rolling type of landscape with numerous river valleys. For the most part I had it on cruise set to 62 although kicking it off if I caught it in time before it started down shifting and self braking going down the grades. Most of the more substantial grades its shifting into 7th I believe as 8th just doesn't have it. Total distance round trip was 643 miles and my overall average and I did refuel three times in all, figured out to 17.65 miles per US gallon. My best fuel mileage section refuel within all of this figured out to 18.46 and these are all hand calculated figures. I find if anything that the trucks computer can be over optimistic, sometimes its pretty close but other times its stretching it. On paper persay in theory the truck would have just about made it on fumes for that whole drive without refueling once.    Which made me think of the topic thread of the wonder if these trucks could do 20 mpg and that is a good question, certainly would have to be on an easy going flat highway, no head wind, the right temperature, not packing around a bunch of dead weight and puttering along even slower than I was I would suspect and going steady and not stopping to smell the flowers or take a piss !. It probably is possible but not without effort to attain that with the wind resistance and weight of these trucks. Of course on my drive most people are passing me if they have the power as per loaded highway tractors, never mind a lot of speedy vehicles but the speed limit is 68 and most are at or well over that.

      Ac not keeping up

      Monday looks like a good day for the dealer to test an ac issue. Hopefully it all turns out good.
