Hi all,

 

I created an online survey to better quantify the issues surrounding our trucks. The goal is to get more accurate numbers. The survey is open to *everyone*, including those with no vibration or buffeting issues. It's 2 minutes of your time and can only help size up the issue(s) at hand.

 

No personal information is required, other than the last 6 digits of your VIN which will be used to weed out duplicates. The VINs may be useful to GM, if/when the results are shared.

Please help promote it.

 

Thanks

I've had my 2015 Yukon XL back for 1 day after it was in the shop for over 3 weeks (this time). The buffeting is the exact same, with no improvement whatsoever. I am having 500 cheap business cards p

Before my Suburban I had a mini van. The burb is definitely an upgrade all around. That poor van got beat to shit. Plus the towing capacity, which is a necessity for me, was way way to low. I think the SUVs are in a different class then the Mini vans.

Can your share your experiences with the new Yukon that you had for the weekend?

 

 

Put about 100 miles on it and it was great. There is slight buffeting in it but it's less than any I've driven and I think it's the level of buffeting that most that didn't know of this issue would buy the truck and never look back. No vibrations which was huge for me and although I ended up going with a black SWB (I initially picked up a white LWB) I don't feel like I settled. I even went back to the dealership today to drive another black one with HUD and adaptive cruise just for one last comparison and I realized that I couldn't even see the HUD with my sunglasses on (which I wear 90% of the time). Adaptive cruise is cool but I wouldn't have added it if I were to special order a Yukon so it wasn't a deal breaker. I have always loved how black cars look but have liked white better. Once I saw the Yukon Denali in black I couldn't pass it up. I lease so worst case I keep it for 3 years...best case, I'll probably get out of the lease in 2 years and into something different anyway. I would bet I have driven 16-17 Yukons/XLs/Suburbans/Tahoes.

 

GM getting the VIN for this truck was the last thing they needed to get things wrapped up. Picked up my check from the dealer for the last 3 lease payments plus the personal property tax that my county charged. Aside from tons of dealer visits and having to not actually drive the car I picked out for 5 months, it could have gone MUCH worse. Hope to have things wrapped up by weeks end but there is a pretty massive snowstorm in the forecast for weeks end. Would love to have it to play around in the snow.

 

I will be sticking around here and will continue to press for action from GM.

Well the service center called me and stated they only notice a drone sound when they vehicle switches to 4 cylinder and Gm has a bulletin out but no fix yet. I tried to explain that my ears are under a lot of pressure/pain even when the vehicle is not in motion and the pain has even caused me to get medical treatment, but he kept repeating the same thing. So I have to come in tomorrow and drive it with a technician. I guess ill have to drive it with them tomorrow. Ill also show them how the head liner bounces up and down violently with the rear windows down even at only 20 mph, and pound there ears out. Sheesh this sucks.

Suggest they remove the headliner and go for a drive, with you if necessary. There will be absolutely no doubt the roof is flexing after they get to observe it realtime.

674 Road tested, found exhaust droning at low speeds when engine is in v4 mode. Checked for TSBS found PIT5404 for problem, Engineering is aware of the issue and is working on an improvement as per TSB.

 

This is what they said about the noise in the cabin that is hurting my ears.

 

674 Road tested vehicle with both rear window halfway down due to vibration if you crack one front window the noise goes away test drove a 2015 Tahoe same thing happens normal

 

This is what they said about the headliner bouncing up and down when rear windows down at only 15 mph

 

;( Im screwed!!!!

Wait, it is indeed totally normal to buffet with a window or two down. The flimsy roof might make it worse but otherwise all modern aerodynamic vehicles that I have driven do this. This thread is about buffeting with the windows UP. If you don't have any buffeting with the windows up you are good.

I basically just have a lot of booming and ear pressure/booming when v4 kicks in. Never realized when the rear windows down the roof bounce and booming was normal. I understand rolling the windows down at hwy speeds but at 15mph? Never experienced that in my 2014 Tahoe, but then again 2 totally different vehicles. Chevrolet customer care just gave me a case number and are calling me back in a few days since the service center at my dealer told me its a problem Gm is aware of but there is no fix at this time and the vehicle is causing severe ear discomfort.

If your roof is detached from the cross bows the booming and buffeting will occur from V4, road irregularities, wind speeds, etc... The roof just has to be attached as designed or all sorts of things will excite it.

 

My 2003 was more tolerant of windows down as well likely due to the thicker sheet metal and the fact that it was much less aerodynamic.

I posted this before, don't think anyone replied but trust your opinion

 

What would be the downside of using something like fiber fix to actually lash the roof bow to its attachment point so that when the glue eventually comes undone, the lashes will still keep them together

      2024 SILVERADO 3500HD DURAMAX CLOGGED DPF AND WONT CONNECT TO TRAILERS

      By ManyCamaroz · Posted

      I had an issue with a new 1985 Z-28 some years ago. The 4WDB's were less than adequate when purchased IMO.  I had taken it in for small warranty services and asked them on three occasions to check them. Each time is was "could not duplicate on the service ticket. The warranty ran out about a month after my last visit and had to take it back for warranty rework. I again complained about the brakes. Well, low and behold, this time they determined the rear calipers were sticking and gave me a quote to repair. They had records as well as O had receipts of each time complained about the brakes while still under warranty. My dad was a life long body shop owner and told me to keep my cool and tell them that I wanted to speak to the GM Regional District Manager. The service manager disappeared for a few minutes, came back and told me they would replace the calipers free of charge.

      Correct way to service 2024 l8t allison trans?

      By Chuck FB · Posted

      I decided to give it a shot and see what sort of a gong show it would be to a pan drop themed oil change on my 2025 gas truck with the 10 speed. All indications I had seen so far was that there was no way that pan was coming out of there due to the cross over exhaust pipe not allowing enough clearance for the back end of the pan to duck out from under the valve body since it hangs lower than the pan to trans mount flange and certainly the filter does. I never touched any of the exhaust mount hardware at all, be that the engine manifolds to Y pipe, the bracket on the side of the transmission, or the two bolt flange further back behind the trans/transfer case. I put the truck up on four jack stands as there was no way I was going to struggle with that lack of clearance under the truck. The truck was cold as it had sat over night so all the trans fluid had drained to the pan, so I drained the bit of oil that would come out of the level check plug at the bottom near the front of the pan and put the plug back in to reduce the ensuing mess after that. Then took out all but one bolt front and rear and then pushed up on the pan and took out the remaining two bolts and then let the front of the pan tilt and spill out most of its contents into a drain pan. I then popped the pan gasket off its two locating nubs and kicked it a bit to the left side so it was no longer on the flange of the pan to get all the clearance I could and managed to get the pan slipped out of there by swinging the front of the pan to the right but keeping the rear part of the pan inline if not slightly to the left of its mounting flange area and lifting the front of the pan enough to keep the rear part of the pan low enough that allowed the pan to "JUST" slip out without forcing anything. I installed a new trans filter and seal and as per GM instructions on this site I torqued the two bolts to that 44 inch pound goal ( they take an 8 mm socket ) In reversing the pan procedure after I had cleaned up the pan both inside and out completely ( touching the outside of a dirty pan and dealing with installing a gasket at the same time would be a disaster ). First I slipped the pan into place and yes it took me a while as it won't go unless its slid in just at the right angles, then once the back of the pan was into the area of the flange mount, I went and got the gasket and then threaded that through the front of the pan and feeding it under the filter etc and finally working it onto the flange of the pan and lining up the two locating nubs to drop into the pan. Then lifted the pan up into place and get a couple of bolts started and check and make sure the gasket is where its supposed to be as the bolts were being put in. I never used any power tools as I don't have any of the whimsy little drive guns, I use what looks like a small screw driver handle with shank that has a 1/4 drive on the end of it and added an extension and those bolts use a 10 mm socket as some times power tools can bite a person if used on delicate parts ( torqued to 80 inch pounds ). Also should note as per rules around pulling the add plug out first, yes I cracked that loose with a 8 mm Allen bit socket on a 3/8 slim head ratchet as there isn't a lot of room to work with there either due to the exhaust on the right side of the trans.    I already had delco ULV oil on hand and of course the quart bottle pump wasn't made for those small cap threads so I had to use some other containers that the pump would fit and keep transferring oil over into them so a wasted exercise there but indeed the small pump did work just fine as ULV oil is thin and easy to pump in summer time weather. I put in 9.5 quarts as per prior minimum recommendation and yes that cut it pretty close as once I had the truck ( off the jack stands so its level ) and the trans oil up to 167f , about 6 ounces came out but a level kit or what have you could throw it off just enough that it wouldn't be enough oil so probably that 10 quarts is a good amount to put in so one doesn't have to add more oil as when its hot I sure wouldn't want to be adding oil so would have to let the exhaust cool. All I do for warming up the transmission is sit there with it in park and rev it to about 2500 rpm and it takes close to 20 minutes to get it up to that lower limit of 167f, weird how it will warm up more doing that then by driving it, I am not real keen on power braking the truck to get the temp up there and don't seem to have to either. By the way I only have 9000 miles on the truck so probably not a very good payback on doing it that soon and the magnets had such a minor thin layer of fines on them so that was good to see and the color of the oil was a darker red then new oil but still looked very good as it should and I've not done any towing with it so its been living a pretty easy life so far. The filter is made in such a way that its next to impossible to pull out the filter media but there certainly was some fines showing up there which makes sense give the trans having to break in.    I hadn't really planned on explaining this much of what I had done since there are various instruction videos kicking around or I think so, as the gist of my message as that by fluke or what have you, for some reason my truck has just enough clearance to slip the pan out from the trans. Of course there is no guarantee that other trucks like this in general will also allow the pan to be taken out without messing with the exhaust as I expect its probably a crap shoot if it will or won't, I was just happy to find out that mine would work and avoid all the other struggling and possibly damaging things in the process,

      Fog Lamps 2024 2500 HD

      By BCGM · Posted

      Do you fellas think Fog Lamps would  be a good upgrade for our 2024 2500 HD Custom ? As you probably know it did not come with them ,  Would you put in GM Chevy parts ? Do they get wired up to the switch panel ( Upfitter or whatever the correct terminology is ) on the dash ? Thanks

      It would depend on what you do to lower it.
