1st dealership noticed the vibrations at 330 miles on the odometer and road force balanced all 4 tires saying there were all in spec after the RFB.

 

2nd dealership:

The GM engineer and pico "identified" 2 rear tires that were out of balance, but, those 2 rear tires were new ones that replaced 2 tires that they said were bad. After another round of pico scoping, the 2 new rear tires that were RFB were now also found to be bad, so another 2 new tires were ordered, RFB and installed. The front tires were RFB and then were rotated with the rears. Whew!

 

Uhm, it might have helped a touch.

 

Also, since the sunroof was leaking the dealership performed the 5429 and 5318B technical service bulletins due to air pressure, buffeting and harsh/hard ride.

 

Buffeting is still there.

 

Dealership(s) have bent over backwards to try to solve these problems.

 

Now I'm being told that I should be lucky because mine rides much better than the majority of them out there. What?!?

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

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 vibra

Given what was recently posted on the facebook page (someone claims to have a video showing roof flexion when the buffeting occurs with their suburban) stating the sheet metal is too thin and needs additional support, I decided to do a quick little experiment.

I think it's safe to say that no one in this thread has had the dealer inspect with the picoscope we need a thread with the owners who have had the dealer inspect with the picoscope

Mine has been measured with the Picoscope as we'll. all it showed was the vibration was at the wheel / tire frequency so the did a Roadforce balance. 2 tires out of spec so 2 on order. But, they did Roadforce first time I took it in and after adjustments, all 4 were brought in spec. So, after some use, 2 tires went out of spec. Just like the pickup owners are experiencing.

 

All this shows is the vehicle is expire leg sensitive to any and all vibrations, and tried to get the tires "perfect" is an unreasonable and futile attempt to solve the real problem - an overly sensitive vehicle. And like AJS800 showmen, the roof skin is at least one of the overly sensitive responses.

 

FYI, I saw mine in the shop when they removed the headliner and re-attached the skin per the TSB. The cross-struts are a total joke. They are so flimsy looking, it's no wonder the roof is like a drum skin. Unless GM gives in there and dies major structural modifications, I doubt much will change with these POS's. Personally, I would love to spray foam the entire roof. But, the amount of wire, side curtains, HVAC up there, would be impossible to repair anything afterwards.

Keep getting something at the rear tire even after changing, then might actually be the rear end that those tires are on. which makes sense if something in there is not adjusted right it'll keep throwing those tires off.. Jus comparing your story to another I heard

I also have major complaints regards to the wind noise in my 2015 Yukon XL.It feels like all the windows are down but there not blowing wind all inside the cabin. I have taken this Yukon at the dealership so many times that I wish I have never bought this truck. There is no fix at this time for this problem. Since the day I bought this vehicle it has been in the dealership 20 times for various other problems. Driver side seat squeeking and shifting while turning. Steering column making loud clicking sounds while turning. Rear wiper motor not working.Rear tailgate trunk not opening. Fog light bezels fell off. Door Bleeker panels loose and almost ready to fall off.This is the worst new models of trucks to buy, its bulit very poor and cheap plastic all around the 2015 and probably 2016 Yukon,Tahoe and suburban to buy. For $80,000 not worth the money. Gm has offered to buy back my vehicle because they know its a piece of junk.

I did that to prevent it being pounded with spam and to keep my entire friend feed from seeing me post on this. There isn't really a login process - you click a button and then i let you in.

It appears that someone finally got the buffeting issue resolved. New headliner, had roof support TSB completed, lined ceiling with dynamat, and had all other roof supports fully supported. Owner claims the buffeting is gone.

Here's the problem with that. The vibration was traced as coming from the tires unfortunately that doesn't determine what caused that issue in the first place.

Ok, the dealer determine there is a vibration, what's next. Still don't know the cause to come with a solution to stop it?

Reading multiple threads (PU/SUV) with tires needing road force balancing, that tells me GM received a bad product from the manufacturer of the tire or wheel. Road force balancing a new set of the same manufacturer's bad wheels or tires, guess what...

An out of spec rear end would wear the tires out of round and out of balance. So if the rear end isn't corrected a new set of tires would just do the same thing after driving on them for a while

Possibly, but you have to first make sure the tire wasn't faulty before it was put on the truck. Road force balancing a tire the first time is one thing, continually doing it a dealer has to look somewhere else. With all the posts of road force balancing, I'm not convinced this GM tire supplier provided a quality product. In order to move on, somebody needs to try a different brand tire. If a different brand tire decreases the shaking/vibration, then the next thing to look at would be to try a different brand wheel. If trying those two things and the shaking/vibration decreases over a long period of time, then the tires and/or wheels could probably be eliminated as a cause.

A good question would be are the vehicles experiencing this all have the 22" wheels or is it both the 22 and 20" inch wheels and what brand tires?

From my experience with previous year yukons some came with different brand tires but curious to see if everyone in here have the same brand tires and same size wheels

      What have you done to your K2 today?

      By mysery1 · Posted

      I have a 2018 Silverado Custom with 156k on the odometer. In the last month I've replaced the plugs, wires and the driver side engine mount. My wife just returned from a trip of about 1500 miles and told me the brakes are making a grinding noise when applied. I drove it and looked it over and this is what I found with the driver's side rear rotor.   I'm going to order new pads and check about having the rotor resurfaced. Hopefully this is easier than the last 2 jobs.   Peace

      5.3 / 6.2 valve covers / oil burning

      By FiLo · Posted

      Any update if the new valve cover help with the oil consumption?  I have a 2014 GMC sierra and my truck is consuming a lot of oil so I’m wondering if replacing the driver side valve cover will stop some of the oil consumption. Thanks

      I bought belts and pulleys for my '20 L5P at Rock Auto a couple years ago. I have used them for many years, and almost always save significant money, especially when I buy maintenance stuff ahead of time.   They carry many OEM parts, which is all I use unless an aftermarket is shown to be same/superior, or if it is an insignificant part or unavailable OEM part anywhere else. RA is usually lower priced, often by a bunch, but parts are sometimes unavailable or out of stock, and I do shop around and sometimes find better prices at other sites.   Be aware that you pay shipping, and if you buy multiple items and they are coming from different warehouses, the shipping can kill the advantage. Planning ahead is best if possible.   If you have a transmission service in the near future, check out their OEM (AC Delco ULV) fluid, usually MUCH less than anywhere else.

      10L1000 anyone with High Mileage ? I hate Damocles....

      By Deadwood · Posted

      New member here, very long time occasional guest. Saw this thread, thought it would be a good time to contribute someting. It is only my experience and not a claim that everyone will have the same.   I bought my '20 3500 L5P new and have put 99.9% (literally) of it's current ~400k miles on it myself, with over 50% of that towing loads between 4k to 15k, and to me this truck has been nothing short of amazing. For the first 235k I had zero issues, and from there until 321k I replaced a NOx sensor, two failing glow plugs, and three of the notorious injector connectors. I believe this truck is in part, a testament to good luck, but also good care and following a decent maintenance schedule (I also keep meticulous records.) As a result, it looks as good as a well cared for 70k rig, up and down, inside and out.   At some point before that 321k mile mark I began to get a little spooked about the 10L1000, especially the valve body. Word of mouth about potential issues prompted me to jump on the net to sift through all the noise and determine what all the fuss was about. I routinely take long trips, coast-to-coast and points in between, so roadside breakdowns can be '...a thousand miles from nowhere' and a bit of a challenge, and though I had no issues, my guard was up and activated.   And then I stumbled across a chance to salvage some parts off a new 2025 that had been wrecked in transport. I grabbed a few wear items (alternator, pulleys, etc.) and on a whim asked what the ten speeder would cost me. It was cheap...really cheap. I knew some changes had been made in the '24+ version 10L and were supposedly not compatible, but I called service/parts at my local Chevy dealer and asked why and they didn't know. A call to a well known aftermarket transmission outfit revealed it was very likely it would be fine, but to them not 100% sure.   Because it was cheap (really cheap) and I was spooked, I took the chance. Had it installed by a local shop and it worked like a champ, shifted just like the original. At it's first service at 37k, I had the shop put in a Next Gen valve body kit, which after some initial hiccups and rough shifts, smoothed out though with somewhat firmer shifting.   All that said, I have a very serious concern about my newer transmission as just two weeks ago it suddenly began to exhibit a strong reluctance to engage forward or reverse. It was a bit past due anyway so I took it in for service. The reason it was sticking was due to 'glitter' in the fluid clogging the filter...not good folks, often indicates a converter giving out. We ended up going ahead with the new filter and fluid, first to see if it would move and shift, and then if so buy me a little time. It did, and I've driven it over a thousand miles and it is shifting smooth, no noises or slipping. Regardless, it looks like a third gearbox is in my future so I can resume taking long trips with some confidence. In the very short term, my curiosity will have me examining the fluid to check how much glitter has reappeared.   An earlier poster had alleged, in the context of 10L100 failures, that it is another example of how we seasoned citizens somehow descend into hysteria, lose control of our senses, and react irrationally after brief encounters with the idiocy of the internet infosphere. Let me say (and I have used and abused said internet since it's infancy) there is no segment of the populace that has a corner on over-reaction to digital garbage. Just as my offering of experience in this arena is purely anecdotal and should not be considered gospel or all-encompassing, I believe it is still worthwhile information to consider, along with other relevant anecdotal experiences about things like complex transmissions, especially when balanced with other sources.   So to answer the original question, yes I got high miles out of my first 10L, trouble free for 321,000. Now I really wonder how much longer it would have went. Did I 'overreact' to the internet ghouls by replacing a 'good' one with a 'bad' one? Maybe. Who knows, the thing might have taken a puke a 100 miles later. So I'll just fix it again, then move on and start thinking about all the other stuff that will eventually wear out. It still has the original brakes (they're at ~60%), original injectors/pump, turbo, water pump, etc....pretty much original everything. Knock on wood.

      6 Speed vs 8 Speed

      By swathdiver · Posted

      At peak temperature.  They get to cool down and warm up more, especially those with the external cooler.  I have three GMT900s and one of them has over 225K on its original transmission.  Fluid gets changed about every 36K miles, all of it.     It's not the bean counters, it was the government.  They had to meet CAFE standards and other government requirements.   To get around that, we tune them and modify them to our liking.
