But, having had several GM vehicles over the past thirty years and had vehicles with both dimensions I have learned that 20's are the way to go whether talking ride, wear, cost, you name it.

Yeah, same here, you're on point with this. I would think though as far as ride, if a manufacturer provided a 22 or more wheel for a truck, that size should have been tested for effectiveness and compensated to provide for a good ride? Don't seem to be the case with the GM truck line from PU to SUV, 22 inch wheels and larger may be aggravating some of the other issues going on with the truck line.

ANYONE ELSE HEARING LIKE A BUFFERING SOUND? MAKES YOUR EARS FEEL LIKE THE WINDOW IS DOWN, BUT IT IS NOT? I TOOK IT BACK TO THE DEALER, THEY HEARD IT. WE GOT IN ANOTHER 2015 YUKON XL AND HEARD THE

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

I've drive 4 different Denali XLs...all 4 wheel drive. Three of them had 22" tires & one had 20". All 4 of them had the buffeting & booming issue. Apparently, the size of the tires doesn't have any impact on the issue. The one with 20" tires was one I had special ordered but didn't take it because of the problem. I'm thinking about getting a Mercedez 450 GL instead.

As I see it the larger wheel size is really to keep up with current fashion. Big wheels with rubber band thin tires are in and that is what sells. And they ride like crap.

 

While the smaller and stiffer tire side walls help reduce roll in a sports car they are far from forgiving in ride quality. They just cannot absorb bumps and pot holes as well as tires with more sidewall.

 

If the overall diameter of the tire is the same (which they are on our vehicles) a 20" tire has more sidewall then a 22" and an 18" has more sidewall then a 20" wheel. The added sidewall material increases the "suspension" a tire can provide at the cost of high speed turning performance. I would not call our vehicles high speed performance vehicles so why use that tire and wheel combo?

 

I ordered my Suburban from the factory so I could get just the bells and whistles I wanted, and I ordered 18" wheels because the ride is superior to 20" or 22"'s. When I am making my 600 mile commute from CA to OR, I could careless what my tire/wheel combo looks like, I enjoy a comfortable ride.

Willyspu, no argument here. Guess 18" wheels have to be special ordered for typical 1500's these days? I haven't seen 18" wheels on a GM dealer lot on anything but serious work trucks in years and they had heavy duty 6 or 8 ply tires which would ride rough as a cobb. But, what you did was smart thinking for sure.

 

Btw, noticed in your member description "1956 Willys Wagon". My first car when in high school was a 1952 Willys Wagon. Mine was two wheel drive, three on tree with overdrive. with 6 cyl L head engine. Well, it wasn't a true L head; intake valves were overhead valve pushrod and exhaust valves were L head. Don't think I've ever seen this configuration since. Anyway, had a lot of good times with that vehicle :)

My 2016 Tahoe has 18s, had them as it sat on the lot. I just hit 1000 miles and haven't had any of the problems described in the thread. I love it.

Hello All. Can someone who has had their vehicle recently serviced for the buffeting either post or PM me the latest service bulletin number their dealer is working off?

I had the 20" Denali machine finish wheels and new Michelin Premier LTX tires installed last week and will say 99% of our buffeting issues are gone. I really wanted to stick with the 22s but didn't want to risk it. Even though it seems as though our roof bows may be detached, I'm not going to pursue having the roof TSB done at this time. Leaving for a 2,000 mile trip later this week and will really be able to test things out.

Our yukon has the "shake" problem and is exactly how it is describe. The shake will be my new fix as I think I've eliminated 99% of the buffeting/pressure issue. Four different sets of wheels and tires later.

 

However, outside of the shake, i can't get over how rough these trucks ride (currently on a 1000k+ mile road trip) ... Very harsh and jerky jittery like. I dropped down to 20" wheels and still not satisfied with ride...almost like there's no suspension...hard as a rock where every bump is felt. I don't get it.

ajs, there is a TSB for the rough ride if equipped with the magnetic ride suspension. My Suburban LTZ had the same issue and following the TSB my dealer replaced some of the suspension components (shocks and struts I think). It made a significant difference in the harshness over bumps. Yes, the feel is more disconnected from the road but it's a land yacht, not a sports car, so it works for me. Mine is a 2015i, and I was told the updated parts are standard on the 2016 models.

Ateam_burb: Any idea what the TSB is? My 2016 Denali rides like a potato wagon, stiffer than any car I've ever owned or driven in 30 years of driving.

This is so ridiculous. GM refuses to admit there's a problem.

Wow! I knew there was vibration/buffeting problem but I didn't think it was that severe. Makes me sick to my stomach thinking people drop hard earned money only to have issues like that.

Any news on the 2017's ???

Or is GM going to let their reputation totally go down the drain ??

      Monday looks like a good day for the dealer to test an ac issue. Hopefully it all turns out good.

      Intermittent no-code issues on 2022.5+ V8 trucks — what did the shop fail to capture?

      By bluev8 · Posted

      That makes sense, and I think you are describing the real product problem. Capturing data is the easy part. If the owner or technician has to manually dig through five minutes of millisecond-level logs, the product has already failed. The device would be at the ECM harness, not at the OBD port, so I agree that data retrieval and event marking need to be thought through carefully. The way I am thinking about the architecture is: The recorder itself should not depend on a phone, app, Bluetooth, Wi-Fi, or cloud connection to capture the event. It should always keep a local rolling buffer and lock the event locally. A button, phone app, or small cabin device would only act as an event marker. If the driver feels a stumble and presses the button 10–30 seconds later, the pre-buffer has to already contain the useful data. For data retrieval, the practical options would be a sealed service USB lead, Wi-Fi download, or a phone/cabin companion device. I would not expect the owner to remove the ECM-side module or work with raw files directly. The cloud or AI side would be for interpretation, not for capturing the event. The truck may have no connection when the issue happens, so the evidence has to be saved locally first. After that, cloud processing could help decode the data, compare it against baselines, and generate a readable report. For the first version, I would keep the automatic triggers conservative and objective: driver event marker bus-off error passive voltage drop / brownout device reset FIFO or queue overflow a normally periodic message disappearing side-to-side communication mismatch, if the topology supports that For “learning normal,” I agree with your point, but I would not want to overclaim it as automatic root-cause diagnosis at first. A realistic first step would be learned baseline comparison for that specific vehicle and operating condition. For example, a value would only be compared against similar conditions: RPM range load / MAP throttle position gear / vehicle speed coolant and oil temperature battery voltage AFM/DFM state, if decoded and validated Then the report could flag things like: this periodic message disappeared compared with its normal timing this value deviated from this vehicle’s normal range under similar conditions the same abnormal pattern repeated after the same type of event the anomaly occurred together with voltage, oil-pressure, misfire, or communication changes But I would still call that “abnormal pattern detected,” not “replace this part,” unless there is enough validated repair data behind it. So the intended product would not be “here is a huge log.” It would need to be an event package: what triggered the capture how much pre/post data was preserved what changed before and after the event whether the device itself reset, overflowed, or saw a bus error selected graphs around the event raw data only as supporting evidence From your perspective, what would make this kind of report useful instead of just another datalog? For example: What are the top 5 parameters or events you would want highlighted first? Would you trust a learned baseline for that specific vehicle, or would you prefer fixed thresholds? How much false-positive flagging would be acceptable before you stopped looking at the reports? What would a one-page report need to show for an independent shop to take it seriously? For misfire, AFM/DFM, oil pressure, or U-code complaints, what would you want the tool to flag automatically?
