I recently bought a 2015 and have a whistling noise when I get to around 60 MPH. It sounds like it is either from the roof lights, XM antenna or possibly the windshield. Anyone had or heard of this before?

Maybe they should retro fit your truck with the new power extend and fold mirrors that should have been on these trucks in the first place, duh.

I'm having the same problem with a new 2015 GMC Sierra 2500HD Duramax. I've spoken with GMC customer service--they were no help. I captured the noise on my phone and played for the dealership. They

I was on another forum and some over there said their Dad's truck had the same issue and it was the windshield. Local dealer fixed the problem. I have not taken mine in yet, but will let everyone know the outcome.

I have the same problem. Would love to figure out what is causing it.

I have taken my 2015 in for an oil change and they were not able to duplicate the whistling noise and gave it back. I asked if I could take someone with me and show them and they sent a tech with me. We were unable to duplicate it but I had a recording of the noise. They suggested giving them the truck and they would put me in another vehicle while they tried to find the noise. I am giving them the truck tomorrow while I am out of town for a week. I will let everyone know what they find or don't find in a week.

I got back Friday and the dealer said they tightened the drivers mirror. After driving it for a while yesterday, the noise has not been fixed. I talked to them and they told me from the beginning it may take a bit to figure out where it is coming from.

I will be setting up another appointment to see if they can find anything else.

Maybe the roof is separating on the cross members like several of the new Yukons...

That don't sound good.

No its not! Go check out the k2xx suburban yukon forum on here and there is a big long thread on it. But I really hope that it's not happening with the HD trucks too. Lots of these trucks go for north of 60k and that's a lot for a vehicle with separating roof panels. I know what it's like to buy an expensive truck that goes south fast.

All,

I think my dealer has hit the mark with the tow mirrors. They tightened up the drivers side tow mirror. I have been driving my truck for two weeks now and I have not hade the loud whistling noise I previously had. I still have a faint whistle every now and again. Nothing like it was. I am going to take it back to them and see if there is anything else they can do for the tow mirrors to get ride of the every so often noise.

      OCI, not when but why?

      By Chuck FB · Posted

      I certainly could be wrong but I hear of pickups far newer than that 2007 cutoff which may not be going to the wrecker but are having engine work done and be that a reman engine or new engine or trying to repair the existing engine. Some of it would be design issues as per the cylinder deactivation system that GM has and one of those lifters wiping out the cam and the question of oil changes moving the needle or not on that whole mess, or in the case of Ford pickup engines that have the long timing chains and wearing them out and the roller followers and phasers and some of that certainly goes back to oil change intervals. But in those various cases the truck has all sorts of life left in it and so the unfortunate owner and may be original owner or used market owner that is pouring money into repairs so the truck is not seeing the salvage yard yet but damage is happening by infrequent oil changes. A friends son had bought a 2018 I think it is half ton GM and it had some sort of extended or used dealer warranty on it and of course the lifter issue bites and its rattling and so the dealer had to swallow the bill and was at least 7000.00 and I think they only replaced what they felt they had to replace so yeah, I can see that being a ticking time bomb in the not too distant future. Would frequent oil changes cure all these engineering "marvels", probably not but some engine designs have shown that they do much better if the oil is changed a lot more often then if the manufacturer service claims are followed. New trucks cost so much that there is an incentive to keep the existing truck on the road by repairing.

      Tranmission stays in Low

      get a good code reader, and find out what problems the truck has noticed by reading codes. cheap ones can only get basic engine codes, you may want to get one that can get codes from all the computers in your truck.

      This is sort of my point, salvage yards aren't overflowing with all these 'poorly' maintained trucks - excellent/good/servicable condition otherwise, salvaged only as a result of a bad engine from poor oil change regiment.    In my area, there are no 2007 to newer gm trucks/suvs in any salvage yards. A few are in the 'recyclers' with very obvious reasons for being there - wrecked.

      Stabilitrak conversion to Z71

      By asilverblazer · Posted

      Stabilitrack was a stability control, traction control system, that functioned independently from the transfer case.   Z-71 has nothing to do with the transfer case or differential.   If it does have an AWD system, my memory recalls this being specific to the Denali trim, converting won't be as simple as swapping out mechanical parts like differentials and transfer cases. It will require reprogramming at a minimum. Long story short, not likely worth it.   Pulling a fuse, may disable the AWD system, it might also prevent any other transfer case functions.   However, the AWD case was generally based on the same transfer case you refer to in the 2006 Suburban. If it still has a 4-High and 4-Low where the transfer case locks and splits power 50-50 front to rear, what are you gaining by changing anything? A true-rear wheel drive only, what good will that serve? Not enough to go through the trouble of changing out all the parts.    Generally, all the factory systems will handle a 33" tire and re-gearing. Probably a 35" tire too, if you aren't driving like a caveman. If 35" tires are in the plan...   If you do plan on driving like a caveman or are fully committed to 35" tires, an entire re-think of the build is probably in order. Starting with square one, an IFS front end isn't going to be the best starting point for 35's and caveman driving.

      Oil Consumption

      By PunchT37 · Posted

      1/2 qt over full ain`t gonna hurt $h!t. Most times, a whole qt won`t either. Most have windage trays now. As long as the crank isn`t slapping itself in the oil, it`s not the end of the world.   We used to overfill 1 qt at the track, at race time. Better to have it over full than having the pan sucked dry at 6500 rpm`s.
