I posted the work order along with a link to the video as a review on the dealership's website. Maybe that will get some sort of response, because as you stated and the video makes clear, that is not a normal noise level. I've never had a GM before but I'm starting to learn this is par for the course when it comes to warranty issues and getting them taken care of. Pretty much have to be persistent and in it for the long haul. Good luck with your case as well.

Honestly, I have had great luck when dealing with GM on warranty issues, but like you stated, it takes time. As hard as it is not to do, try not to make enemies with the dealership (whichever one it ends being) doing the repairs. That is why you need to stress to GM how they have treated you, they will reach to them and make sure they are nicer going forward.

I opened a claim with GM this past Tuesday. I need to call and follow up on it. Good advice, thanks!

Thanks.  Mine has been out of warranty for quite some time, and out of extended warranty as well.  I've been going to this dealer for close to 10 years.  If I ever get my truck back I'll post a video of my compressors going so there's a comparison of overkill aftermarket vs factor installed not working right.  :)

I'll upload another video this evening, but had a pretty good breakthrough this morning. My wife pulled over after the noise started and climbed in the back seat. When she set on the third row far right seat, the noise would stop, and then when she would get off the seat it would start again.  Passed the video over to the Service Manager at the local dealership (the second one where we bought the car) and hopefully it will help them narrow down what to investigate next time we can bring the vehicle in. Another twist in the saga but hopefully narrowing down the issue.

 

And here is the video, I don't know what to make of this other than the issue is possibly being narrowed down.

Open a claim with GM, let them know how unhappy you are, and let them know how you are being treated by the service managers (personally, if my wife came home in tears, I would have driven there and punched the service manager in the head). Don't threaten them with a demand to buy back the rig, or Lemon laws, just be firm and demand that you as a customer of GM are not happy and that you feel like you are being treated like crap! And, want your really expensive vehicle fixed so it functions normally.

I did this and today was contacted by GM. The customer service rep was extremely helpful and listened to the entire story. I've also sent the initial work order of the dealership acknowledging the issue and the second which the service manager essentially used to blame the issue on us along with multiple videos to support that the vehicle is not "operating normally" as stated in the second work order. For the first time in the process I actually feel confident the issue can get resolved and like I have an advocate working on my side. Time will tell, but slow and steady going forward.

Patience and persistence. Glad it is going better, they will take care of you. Most do not do these steps and just settle for a less than desirable vehicle.

A good lesson learned here is that if you have a case open with GM customer service, it is tied to a specific dealership and not the vehicle (it may be the vehicle as well but it is definitely tied to a dealership). I discussed the situation with them and told them I had moved the vehicle so they changed the dealership on the case which allowed me to give another round of formal feedback on the dealership that I originally attempted to have the repair done at. Make sure that you keep GM customer support updated on your situation if you have an open case so they can keep the status updated. Hopefully others find that helpful.

I have the same noise coming from the driver side rear end. I have a 2019 Chevy Suburban and the noise started about a month ago. I use the vehicle for car/limo service so it runs idle in front of high end resort lobby a lot and it is not a good look for my service when people are getting ready to walk in the car and they hear this loud compressor sound. Inside the vehicle though, it is not as loud as in your video. As my high season started just recently, haven't had a chance to take it to dealership yet.  But, whoever says this is normal operation, is clueless. I didn't have the noise during the first 30000 miles and now I do.

Good luck. They don’t care. All they will do is provide lip service for a while until they tell you nothing is wrong but you. I can’t even ride in mine without a pressure noise hurting my head. Complained about it within a hundred miles of owning a new 2019 Yukon Denali Ultimate 4x4 and after months of back and forth they said it is performing as designed. So designed to be shitty and will be my last GM.

After about  1 year my 2018 compressor  started constantly  running. Took it the dealer  they immediately diagnoses a leaking  rear air bag or strut something like that they ordered  the part was fixed  1 week later. Now it hardly  ever runs  unless you load the back up excessively which i believe  is suppose  to be how it works. The compressor should not be running  excessively especially when you  dont have a load

Brand new Tahoe, same issue.  On a trip south, compressor started running almost constantly... It will stop, but in few seconds to a minute or two, kicks in again.  Brutally cold, so haven't looked at anything.  Was hoping to find a simple == dealerless solution... Sad they so often say "oh, they ALL do that..."

 

How do you open a claim with GM please????

It’s not normal to run excessively. My 18 Tahoe only runs occasionally if the back is loaded with people. You must have a leak somewhere.

My '19 Tahoe compressor started running almost constantly, only 4000 miles.  I determined myself the left rear shock was leaking.  Took it to the closest dealer and they ordered and installed the shock.  Problem solved... for now...

      Cam chain tensioner question

      By B14Sierra · Posted

      So I'm in the middle of a DOD AFM delete on my 6.2 L86 Sierra. I had a pick holding the tensioner but after I got the Cam phaser gear off I was cleaning off all the rtv and apparently I didn't have the pick seated far enough in. I bumped it and the tensioner sprang forward.  I think everything is good but I want a second opinion. The top of the tensioner is just a looped piece of plastic that rides in that channel right? There is no spring or anything is there? I got the gear and chain back on and it seems tight and everything looks right. I'm hoping nothing fell out.

      No low range 4 x 4

      My 2015 1500 LTZ Silverado suddenly won't go into 4 x 4 low. It will go into 4 x 4 high.

      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

      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.
