That vibration at 30 mph could have something to do with the fuel management system. (engine going to 4 cyl) I notice it only when mine is running on 4 cyl. It just sounds like a low rumble.

 

What I have is a constant thing, and it varies depending on the road.

It varies from a hum feeling to a tremble that will shake your hand.

Yours sounds like a different issue.

My truck came with continental tires, been smooth. Took a small Hwy trip yesterday notice a little shake just when it was ready to go from v4 to v8. I don't think I would have notice but after reading some of the post on here, I think I may be becoming a little paranoid. Maybe Im not alone.

My passed posts have part numbers and what they did. Maybe it is a combination of things. I still have the drone at 40 thru 50 but I just try to keep it out of overdrive and it stops. I had the vib in the wheel on the hands. That made my fingers tingle. I can live with the drone. Choices of another vehicle are limited.

Also I have drone whether in v4 or v8. Drive in tow haul in tow and it goes away....

It wont let the trans go into overdrive or last gear.

A continual soft vibration or is it harsh.

Mine has a vibration that ranges from soft to a bit annoying.

Yes, you described it perfectly. I feel it through the steering wheel and sometimes through the gas pedal.

Try Michelins before you give up. Look back at my posts to see what they did to fix.

Yes, when they replaced the tires, they install the same Bridgestone tires that came on it from GM. I can't bring myself to purchase $1,000 worth of tires for a brand new truck.

KARNUT has it figured out it is simply MASS HYSTERIA. Now go take your meds and shut up..............................hahahahahahaha.................now myself here I am going to start pricing some new tires cuz my MASS HYSTERIA is sooooooooooo real that I cannot shake (Shake and Vibrate) it off. Pun intended.

No really power of suggestion, I'm not saying people don't have problems, but I find myself being more aware. Or paranoid.

They put them on no charge....

5.3 3.42 ratio. Michelins and vibration dampeners fixed it. Look back through my posts to get part numbers.

They also did something with the exhaust. There is a flap back there that is supposed to open and close. They made it so it stayed open. Could possibly be choking back for fuel mileage or something. Government is trying to make the manufacture squeeze every MPG that those of us who choose to drive pick ups that have balls suffer.

There I said it.....

Not $1,000. If you have discount tire nearby. They will give you something for your take offs. Just cannot see paying 40-50,000 for a truck and driving on low bid oems. Life is too, too short for fighting with gm. Even it the new Michelins do not fix it you are way ahead with a better tire and it will ride, handle and stop better than now.

How does it affect anything it is just a little flapper valve? Mine is mounted to the muffler outlet just in front of the rear axle on my CC SB Z71 4x4 SLT. It looks like something that is going to rust and freezeup either shut or partially shut in the future. Kinda stupid looking for an exhaust system. Who has removed it or locked it open and kept the stock exhaust system? Any effects maybe a louder drone noise or something? Oh and how can you be sure that the valve is 100% open when you lock the worm gear clamp on the spring head there is no way to see the flapper itself?????

Have a loaner '14 SLE while my trk has some work done. 20 inch SLE wheels with GY LS. Thing shook so bad on drive home I thought a wheel was loose. It has to be bad tires or balance. I can tell these GY LS are really not a good tire. Even at slower speed and no shake, they are harsh and ride rough. Feel like they are inflated to 60 lbs (they are not). The GYs LS are No comparison to my Michelins on my truck.

 

If this was my truck, I would dump these tires for Michelins so fast. Even if I had to get a loan to do such. Then trueing/high speed balance on the trk. IF still an issue, then I would return to dealer to look elsewhere. OH, I would be sure to check the wheels for run out etc...when changing tires.

This proves that vibration problems on these trucks are not as rare an occurrence as some GM apologists on this site would lead you to believe.

    • Would you supercharge the 6.2L on a 2021 GMC Yukon Denali XL with ProCharger?.... 605HP is the stated number without going crazy - it's not the LT4 682HP package, but I'm tempted to install it... This vehicle was ... not... recalled on the engine swap - but I don't really know if that means ...don't do it... or do it;)    Maybe i should start a prediction market pool on it in case it blows up;)   Any thoughts appreciated - I already OWN the supercharger - stopped the installation when the recall was announced and now it's taking up space in storage until I can solve an electrical issue with the vehicle...  4th GMC suburban-equivalent truck - I like them a lot - when they don't a) discharge their batteries randomly, or b) throw a rod at highway speeds;)
    • We tested the sleep mode with an ammeter in series with the negative battery terminal - 30amp fused - so we do know the actual shutdown and non-shutdown current draws and timing of the shutdown sequence.  We just have no protocol information to determine what module is issuing the network keep alive.  
    • TrueBlue...Even if you don't have that info stuff displayed, If Mr. Computer thinks there's something you should know about, it will pop up a warning message no matter what else is being displayed. I keep the speedometer displayed all the time, yet the brake pad message pops up anyway.
    • BTW, the 11.5amp draw is all the usual systems active - it's not a single draw - that's the "we're all awake" state of the vehicle - forinstance if the power steps are actuated, the draw will spike to 22amps for that operation.  when the battery is disconnected and then reconnected, the vehicle shuts down that one time only - and we see a 10-15minute progression down 11.5  10.5  9. 8 6. 5. 1.6... 500ma... and then off to sleep at 40 milliamp... as expected.  So we know it's a module that is simply refusing to allow the SDGM to proceed to the sleep state.  We do NOT think it is the telematics VIM module - since we already duplicated the problem with the "VIM bypass" solution installed (we reverted that since it also disables the gmc app - but it does not appear that the telematics system is the culprit).  We've replaced the rear heater control module, tested without the wireless charger, and the other modules on CAN Bus 5 - but still something is keeping us awake and removing X2 from SDGM allows sleep to proceed.  We cannot diagnose from OBD since OBD drops off at about the 9volt level in sleep mode and we can't communicate with the vehicle - also we can't trace the SDGM internal packets from the OBD side - we have Autel Ultra.   Any ideas on why disconnecting X2 would allow sleep to proceed appreciated.  This is no longer a repair situation - this vehicie is simply unusable in this condition and NOBODY at GMC Dealer can even understand what it is doing.  This is crazy.  We made these systems too complex and now we're paying the price.
    • Did this ever get solved?   I'm chasing 2021 Yukon Denali electrical issues - vehicle will not enter sleep mode - we can disconnect and reconnect the battery and it will sleep - but that's likely because we powered down whatever module doesn't correctly sleep.  once we start/accessory the vehicle and turn off, it will stay at 11.5 amp draw with something keeping the SDGM alive - it appears to be activity on the X2 segment, specifically CAN FD Bus 5 - but we don't know which device and we think we've already isolated all of the devices on that segment - so what keeps the BCM and/or the SDGM alive is unknown.   I don't yet have a packet trace from CAN 5 (and since this Global B we might not get much info from it) - but the vehicle has been down for 8 weeks and previously GMC Dealer was unable to resolve "kills battery" issues with this particular vehicle - so I'm at a loss - it seems to be beyond local repair capabilities - and the number of "telematics keeps vehicle from sleeping" posts indicates this whole architecture has major issues - I hate to say it, but we might have to install a battery cutoff switch on the front grill - one of those red boat switches - to turn off the vehicle.;)  Any pointers appreciated;)  I just bought a CAN FD interface and I'm planning to try Savvycan and Peak Can SW to triage this further.
