What is going to happen when we need new tires from wear out . Do you suppose the local tire shop is going to let us try 14 sets of tires claiming they all make our truck vibrate ? LOL.

Well folks, I did it. After all the failed attempts at the Chevy dealer I traded it in for a 2015 Ram 1500 Larame. I have to agree with the other folks on here that have done the same thing, it was th

Apparently you and the other customer reps don't care. If you or GM would care y'all would put more effort in the matter. Just coming on the forum and stating the same repetitive posts and being a 3

Well I have some good news and bad news about my truck vibrations. Good news is that my truck has a significantly less vibration at speed. The bad news is my truck has significantly less vibration. Fo

Better yet.....The tread on your all season tires is too aggressive. Uh yeah

Exactly, what is everyone going to do when new tires are needed? The real problem is not tires.....yes ou can have tires that make your ride vibrate, but I bet any tires they throw at this truck design will still shake!

 

Removing the truck's tires, and placing the truck on jack stands by means of the axle supports should duplicate this issue at its known problem speed. Rhythmic energy issues can be duplicated, just need to create the conditions, so a good perfectly "balanced" tire may help mask these vibrations until the next tire change.

 

Testing should include steel, rubber, and energy absorbing components clamped to frame and cabin. This can be preformed by use of "c-clamps" and placed within 6-8" of cabin, frame, engine mount areas.

This should change your truck's Rhythmic energy being released.

 

Good luck with your truck.

Lol....Your air intake possibly causing your suspension to shake, way to go GM

I was told my aftermarket exhaust was probably causing my vibrations.

-Mild vibrations at any speed. I can only recognize this vibration due to the shaking of things in my door storage or the rattling of my garage door opener that clips to my visor. Yes I never programmed my garage opener.

 

-Vibrations when I reach 70+. This vibration varies based on road surface and I also believe wind seems to affect it as well. This is the vibration that has caused me the most concern.

 

First, I would like to thank everyone for taking the time to share so much valuable information. I have always noticed the mild vibration on my truck, but it wasn't until two days ago while on a 10 hour road trip I realize the severity of the high speed vibration. I always assumed it was all related to my choose of all terrain tires. I also assumed I was in need of wheel balancing. I took my truck into the dealer for an oil change and wheel balancing 2 days befor my trip.

 

So while on my 10 hour journey it became very clear that the wheel balancing had no effect and my truck was still vibrating. My wife also started asking me what's wrong with my truck. I never discussed the vibration so she was completely unbias.

Most of the time the vibration is a slight anoiance, but on some surfaces its absolutely horrible. It feels like you are driving a 20 year old truck.

 

So I went online and I came across this forum and I have spent the past two days reading everyone's post. I have owned over 30 cars and trucks in my life, let's say I have a car addiction. I have never driven anything that rides so bad at the speeds of 70 mph. The ironic thing is this is my first new vehicle. I have owned work vans with 250k that road as smooth as glass, chevy express by the way. I have always purchased high mill age vehicles in the past, 90k and up.

 

I'm so upset after reading everyone's post. It's clear to me that after 3 years GM either doesn't have a fix or the fix is to expensive. I love my truck, this is the first vehicle that I picked every single color, option, etc, This truck is so sweet, but I need my truck to pull my tool trailer for work. I think I will started the process of trying to get out of this truck and into something else. I don't have the time to back and forth with the dealer, but I refuse to pay 40k for a truck that rides like shit on the highway. Thanks again to everyone for providing me the information to make an informed decision. I wish everyone luck, and I will let everyone know what actions I take to get out of this truck.

 

I also think it would be helpful if everyone gave a good description of there truck, wheels and tire, and the issues they are having.

Sounds like the GM techs need to put these trucks on a 4-post lift, remove wheels, then run the drivetrain through the various speed ranges. If vibration still persists, then the wheels and tires can be ruled out as cause of vibration.

I have done this exact thing. Still vibrated at the same speed as it does when driving down the road.

Haven't posted on this topic since September so here it is: Removed Flowmaster exhaust, removed 20" Denali wheels, replaced with stock 18's on Shi*ty Good Years. Vibration still there. Installed 2" drop shackles on rear vibration decreased some but still there. Going for rear sway bar kit next. Should be in this week will install and update. Also a small footnote, after removing aftermarket exhaust and wheel combo as dealer said still had the problem. I put the 20's with the bfg all terrain t/a's on my burban and no vibration, so its not the wheel tire combo. I would really like to run the 20" wheels but it looks like a no go. I am also having the pinion checked for preload after reading up on that some, as well as entertaining the thought of replacing axles and drive shaft to a steel 2 piece. Sounds like a parts replacement marathon right?

 

Dealer update: When I went through rounds 1,2, and 3 with the incompetent dealer service department they voided the warranty on my truck because of the aftermarket exhaust, wheels, and tires, they even went so far as to have GM customer service notify me of this as well. these as*holes really didn't want to fix my truck.

GM has such a great opportunity to learn from the work/testing done by people like you and so many others responding to this subject, it's a shame they void your warranty rather than contacting your and working with you to help solve this vibration issue. Shame on GM!

I have a Hellwig rear sway bar and my truck still vibrates. Corners and tracks better when accelerating but that's about it. And they can't just cancel your warranty over aftermarket wheels, tires and exhaust. Please Google Magnuson–Moss Warranty Act. They have to prove these mods are the direct cause of your issue. Also judging by this thread and others spanning SUV models on this truck platform, GM can only try to deny service. Edited by Severado

After putting ajustable Bilsteins and load range E tires on my truck the vibes went away maybe 80% of the time. So then I started messing with air pressure on the tires. They are a good sized all terrain tire with max pressure of 80psi. I originally had them set at 50. Now I dropped them to 40psi and it rides very well. Much better than stock and vibe is 99% gone. Only time I feel it slightly is when going up or down inclines overpasses etc. Don't know if this helps anyone but thought I'd chime in

I have said this before, buy from the dealership who sold the vehicle... The dealer would then take the burden of finding a matched set, if bought outside of their doors they will make you work with the tire store who will just tell you FU

Running LT tires at 40 psi can be dangerous because it is too low of a pressure and heat can build up which in turn could cause a blow out. Most of time when going from a P rated tire to a LT tire about 45 psi is what will carry the same load as a P rated tire at 35 psi. Also the max psi of 80 does not mean much for a half ton truck, the only people who would need to come close to that PSI is a 3/4 or ton truck carrying a heavy load and/or towing a heavy load.

      summer road trips in the 2026 2500HD

      By Chuck FB · Posted

      I thought I would use your thread and add to it as I just did my first longer drive with my truck in the last couple of days. I drove from the Grande Prairie area of Alberta down to Edmonton and most of where I drove in the city was the ring road so fairly free flowing but a bit of stop and go as well in the city. Stayed the night and returned home and not too many stops along the way each way but every restart and certainly every cold start sets it back for fuel mileage. Why I say that is I see some people will cherry pick a fuel mileage leg after the vehicle had been warmed up driveline wise before hand and its a forgiving ( easy rolling drive leg for example ) and call that their fuel mileage which can give a false perception of reality. I was not heavily loaded at all but never the less the flip bak cover, rubber bed mat, various tools etc and extra jerry cans of fuel all way up to a few hundred pounds of dead weight so its not an empty truck. The cold inflation tire pressures are set more near the freezing point so once they are warmed up driving I was showing 45 front and over 40 rear and realize high inflation pressures would help a little in fuel mileage but certainly not the ride on our crap sections of highway. The weather was good so was not raining as that can really drag mileage down, in fact I had a bit of a tail wind on average driving home. Most people on here would never have driven on that freeway to visualize it but its got a fair bit of rolling type of landscape with numerous river valleys. For the most part I had it on cruise set to 62 although kicking it off if I caught it in time before it started down shifting and self braking going down the grades. Most of the more substantial grades its shifting into 7th I believe as 8th just doesn't have it. Total distance round trip was 643 miles and my overall average and I did refuel three times in all, figured out to 17.65 miles per US gallon. My best fuel mileage section refuel within all of this figured out to 18.46 and these are all hand calculated figures. I find if anything that the trucks computer can be over optimistic, sometimes its pretty close but other times its stretching it. On paper persay in theory the truck would have just about made it on fumes for that whole drive without refueling once.    Which made me think of the topic thread of the wonder if these trucks could do 20 mpg and that is a good question, certainly would have to be on an easy going flat highway, no head wind, the right temperature, not packing around a bunch of dead weight and puttering along even slower than I was I would suspect and going steady and not stopping to smell the flowers or take a piss !. It probably is possible but not without effort to attain that with the wind resistance and weight of these trucks. Of course on my drive most people are passing me if they have the power as per loaded highway tractors, never mind a lot of speedy vehicles but the speed limit is 68 and most are at or well over that.

      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?
