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

Is it the tires cause when it's time to get a new set I don't think the tire shop gonna be switching up tires for free

Sure they will. I've done it twice now (summer & winter tires), eliminating the buffeting both times.

 

Before agreeing to buy them, tell them they need to have RF numbers less than 15. Better yet, buy them from a GM dealer who mandates those specifications.

 

These new trucks are sensitive. Had I not experienced it myself (twice), I wouldn't have believed it.

Yep. I ordered a new set of Michelin Premier LTX and after explaining to the shop the issues, they ordered 8 tires to make sure I had 4 that RF under 15lbs. Most vehicles would be fine with anything under 20lb RF but not these trucks. Prior to the new set, I had the orig 18", a used set of 22" and another new set of GY 20" tires. The buffeting was all over the place depending on the tires and was by far the worse with the 22" setup. However, the 22" tires were not new and may have been defective or had wear issues as they were already mounted to the 22 denali wheels when installed.

So that's it. Ref load under 15. Do they have 22 with that rating. Has anyone tried

 

By the way this is Cl houn I don't know why this screen name comes up

Friends,

I am coming back to this forum after a long time. The main problem of buffeting lies in the tires. Just replace them with a good quality soft tires, have them balanced properly and the major issues will be gone. However, in winter when the tires become hard some level of buffeting might still occur, that too in the morning when you start off. May be you need to replace tires a bit more often than with other cars too.

 

Looks like the wheel-base is very sensitive to tire conditions for these cars (suburban etc).

 

It is really an enjoyable car once major issue is gone.

@CI houn: I'm sure all manufacturers have different designs and tolerances, probably per model. The tire shop told me that 20lbs was the tolerance for LT tires. Unsure what that is for P-spec tires. I'm sure you can find a good set of 22". Just find a shop with a Hunter RF balancer, good stock and is willing to spend the time to get it right.

 

It took 6 Continentals to get them all under 13lbs. The buffeting ceased. I then mounted my BFG KO2s for winter duty which were balanced to 18lbs, 15lbs, 11lbs and 4lbs with the worst two on the rear. The buffeting returned. 2 hours and 2 tires at the top, they got them all to 12lbs, 10lbs, 10lbs and 8lbs. The buffeting ceased.

 

It is unusual that this new truck platform is so sensitive. I'm just happy that we now know how to minimize it.

They make the michelin Premier LTX as well as a few other brands in the 285/45/22 size. I was very close to keeping the denali 22s and ordering a set in the 22 size but figured it was best to drop down a size given all of the ride issues. If I knew the buffeting would be cured and only lose a little ride comfort I would stick with the 22s. I am not sure if there are any on here that fixed the buffeting with 22s after making sure all tires RF under 15lbs.

What exactly does rf stand for

Road Force, obtained from a Hunter Road Force balancing machine which not all dealerships or tire shops have or are trained on. They cost about $10K each.

I have a 2015 Yukon XL with the cabin noise issue same as everyone else. Been to the dealer and they could not fix it. Dealer says GM is designing a new exhaust system or at least modifying the old one. Something about a baffle near the end of the exhaust system. Noise is terrible, worst around 35 to 45mph when it is in the 4 cylinder mode. If you put it in the towing mode which cause the rpm's to rise the noise goes away. Wife always buys the Yukon XL but I think this will be the last one. Especially since it is taking GM so long to fix it. A fix should have been figured out a long time ago, does not make sense.

Gm told me the same thing on the new exhaust. Its in production now and should be available by the end of June. My dealer has me first on the list to get mine replaced when the part comes in.

      Replacing 2.7L on 2021 Silverado with 2023 2.7L

      I’m definitely interested to hear the end result here.

      Another 6.2L engine failure!

      By MASONV88888888 · Posted

      My 2025 Silverado 1500 had to receive a brand-new engine (long block) under warranty last month at only around 16,500 miles. Before the replacement, the truck repeatedly displayed "Engine Oil Level Low" warnings, even though the Oil Life Monitor still showed around 50% remaining after about 6,000 miles since my last oil change. After seeing the warning several times, I checked the dipstick with the engine cold, and the oil level was completely normal. The next day, the message escalated to "Add Engine Oil." At first, I assumed it was just a faulty oil level sensor, so I brought the truck to the dealership. After inspecting the engine, they found internal cylinder wall scoring and ultimately replaced the entire long block under warranty. Before this happened, I was planning to install a 4-inch lift and suspension upgrade on my truck. After needing a new engine at just 16,500 miles, I honestly don't see the point anymore. I also contacted GM to ask whether my vehicle qualified for a buyback, but I was informed that it does not at this time. Anyway, this experience has left me with serious concerns about the long-term reliability of this engine. I sincerely hope NHTSA expands the current investigation or recall to include 2025 model and performs a thorough inspection of affected vehicles. My biggest concern is that these engines may fail shortly after the powertrain warranty expires. If GM truly stands behind this engine, then at the very least, please consider extending the powertrain warranty to 10 years for affected owners. That would go a long way toward restoring customer confidence.

      OCI, not when but why?

      By Grumpy Bear · Posted

      Without exception but then I'm the odd duck, right? I know what goes into that test, how it is calculated and thus how to beat it. But EPA values are often not beaten by the general public and the government has in past years adjusted the means and methods to come to those values to more closely approximate "Joe Average".    The only real trick to beating that EPA average is don't drive like "Joe Average".    It's the same method you used to profit from "Economic Migration" and in doing so beat the 'stats'. But you, like me, are not "Joe Average".     The thing you don't seem to grasp is this "Purchasing Power Index" isn't forward looking. It doesn't predict what it going to be but looks backward and states what it was. They are not telling us what the THINK, they are telling us what they MEASURED. Example:    Wife says "I'm going to lose 40 pounds by Christmas". May she does, maybe she doesn't but the doctors office who weighed her when she made that statement and again at Christmas only REPORTS what the RESULT was. You and I can banter about what was possible and what aunt Tilly did till the cows come home but the result is the result. Arguing otherwise is.....irrational. That's all I'm saying. This isn't about:      What you are calling a 'Statistic' is a RESULT not a CALCUATION and as a result the RULE. Like gravity as a rule, it can not be broken.

      Rattle in the rear!

      By MASONV88888888 · Posted

      Just wanted to say thank you for posting this. Years later, your thread is still helping Silverado owners.   I bought my 2025 Silverado 1500 in January 2025, and I've had what feels like the exact same rattle since day one. After reading your findings, I believe my truck has the same issue with the cable carrier contacting the rear sliding window. To be honest, I had pretty much given up on pursuing the issue. It wasn't until I recently drove another brand's pickup that I realized just how quiet their cabin was—and how noisy mine has been all along. On my truck, the rattle happens on almost any paved road, gets even worse on rougher pavement, and I can even hear it during braking and acceleration.   I actually referenced your thread when submitting my case to GM, hoping they'll recognize this as a recurring issue instead of treating it as an isolated incident. The reason I reached out to GM first is because my dealership told me they would need to keep the truck for at least two days just to diagnose the problem. I was concerned that even after two days, they still might not be able to identify the source of the rattle before giving the truck back to me. I had also asked a few dealerships about this issue during previous service visits, but none of them seemed to know what was causing it or had a solution. That's why I decided to contact GM directly first, hoping they might already have an official repair procedure or guidance for this issue.   I also hope GM eventually comes up with an official fix for this problem. I have a feeling there are many Silverado owners experiencing the same rattle, but most either choose to live with it or simply don't know what the cause is.   Really appreciate you taking the time to document your diagnosis. Your post is still making a difference years later.
