The way silver spaceship described the vibration on his truck is exactly the same way my truck is behaving down to the tee almost sounds like he is describing my truck. And he is right it dose not always vibrant something triggers it, and I know it's the truck because I have tried the same stretch of road with my wifes Tahoe at the same speed and it doesn't vibrate. By the way I have had up to 4 people lots of times with me in the truck and sill dose the same thing. At first I thought it was just me but after reading silver space ship comments and describe exactly what I was going through, now im not crazy lol. What dose it take to get this truck switched out for another one dose anyone know? Or am I SOL on this one? Y do I have to pay 50k for something that is give me headache what can I do about this?

It's possible that the weight has nothing to do with it I just thought to my self on the way home what changed and that's the only thing. It might ride just fine tomorrow, it's unpredictable. One thing is for sure after having a engeneer test drive it and say its normal the dealer isn't going to do anything about it and I can't blame them. Plus the one I test drove did it too, I would say not quite as bad but very close at times.

I too have this problem on my 2014 silverado w/5.3 4x4 z71. Wicked vibration while towing an aluminum open trailer with two atvs. None under normal conditions nor when hauling a 4000 lbs camper. Trailer doesn't vibrate behind other trucks. During lunch I happened to sit next to two service technicians. They said their is a known prop shaft alignment problem with no know fix that they were aware of. If I am thinking about this correctly a light load squats the truck just enough to create the problem. But a heavy load makes it hard to notice. I love the truck but sledding season is on its way, got to get this fixed soon.

 

Oh that trailer is about 500 lbs plus another 1000lbs of atvs. Creating about 200 lbs of tongue weight. Vibration gets real bad at 55mph.

I have this very same issue on my 2014 Sierra 2WD. I may have a solution (theory) to why it seems to go away sometimes and return other times. I have noticed that on my truck the vibration will get better or worse as I am turning at highway speeds starting at about 65 mph and continuing upwards of 80 mph. I noticed the vibration one weekend on a trip and got the tires balanced the following weekend. The problem seem to be actually worse than it was when I took it in, so I started to really pay attention to it. I started noticing that it would be better occasionally and then worse. I hit a really long bend in the road and that is when I experienced the reason, at least on my truck, why it seems to be better/worse. I felt the vibration cycle from almost gone to really bad and then back to almost gone. It appears that there is a balance issue between the right and left wheels. As they turn at different speeds while turning, they are able to align with each other producing more vibration or offset from each other canceling out the vibration. It never totally goes away on my truck, though. I haven't taken my truck into the dealer yet but I plan on taking it in next week to see if they can check some things out.

 

On the weight subject, I almost daily haul around 4 other guys during lunch and still have the vibration though the speed in town is only 65 mph so I can't say if it is worse or better with the weight since it is only starting to vibrate at that speed.

 

Edit: I forgot to add that I have since had my tires balanced twice with no change to the vibration.

I had a '12 Grand Cherokee, that did the same thing. It drove me nuts. The dealer said that it was supposed to be that way. I think they just couldnt figure it out. I got tired of fighting with them so I traded in on my '14 silverado.

 

I have the LTZ and the ride is super soft, rides like a 80's caddy

So after not hearing anything from my local dealer for 9 days i decided to call and see what's the status on my truck. The rep told me that a Chevrolet engineer came down to check the truck. The engineer said it was the drive shaft and order a new and improved drive shaft and gets installed next Thursday, this will be the third drive shaft they put on. The engineer said he was going to put it on and test drive it him self so let's see how that goes.

I just had my tires rotated today and the vibration is still in the rear of the truck. The only thing that I can think that it is now is the axle. I will be taking the truck into the dealer next week to have it looked at. I will keep you all posted on what they come up with and if it helped or not.

Well, the dealer replaced the driveshaft Friday. Didn't do anything to help the problem. Maybe the 2014 Chevy's are supposed to vibrate.

I haven't experienced any vibration, certainly hope they figure it out!!!

And now it's on the back of a wrecker headed back to the dealer. Surging won't get over 30 mph. This has been one hell of a new vehicle experience.

Just curious, those who have the vibration what wheels do you have? I drove one with 20's and it felt different than the one I bought with the 18's.

    • Question @diyer2 on this line if you please. Are you saying the shudder is the system turning on and off at the frequency of the shudder? Guess I'm asking if you are saying you have seen it do this with the bi-direction scan tool in graph mode? If so have you been able to discern the 'trigger'. Something is telling to cycle rapidly.    My truck just started doing this recently. 197K on the clock. My response has been M5 anything under 55 mph. I treat it like a lugging stick shift. Gear down and let it spin a bit. Engauge M5, then tow mode and then M6 lets the trans stay in 5th but the AFM is active. Smooth like Skippy.    My thought was that as a machine ages the friction gets lower and as the system is load based, the lower friction would allow it to turn on at ever lower rpm until it reaches the lugging point. And yes I am ignorant of any minimum rpm requirement for the system. If you know that would be useful information.    As you know I run a Scan-Gauge II which allows me to watch the On/Off of the signal to the VLOM. While in the shudder mode I'm not seeing is cycle at that frequency or at all for that matter outside the triggers @newdude posted a few years back. Now is it possible that the refresh rate isn't fast enough to catch it? Maybe. It is why I asked my first question about graphing and trigging parameter.     As we have observed from members here the failure point is all over the map miles wise as you note yourself in your opening post. That by itself begs a few questions like fellows that comment on these lifters failing even after the system has been disabled. Long after. 😬   https://www.enginelabs.com/news/tech-tips-replacing-ls-active-fuel-management-lifters-with-melling/   The Gen5 lifters operate the same as the LS versions. In fact they are the same lifter.    https://www.enginelabs.com/tech-stories/sorting-out-gen-v-lt-lifter-failure-with-a-simple-valvetrain-fix/        
    • UPDATE 2: Steering wheel control backlights and control of the cluster can supposedly be achieved by adding a wire to pin 20 of the cluster and tapping it to pin 2 of the main clock spring harness. I'm going to give it a shot - will update  
    • GM Global A pickups 2019-2022 can do OTA programming for the radio.  GM VIP (GM Global B) can do OTAs for almost every module on board.  So a 2022.5 and newer pickup can do OTAs for recalls like the 2.7 fuel flow recall.  EVs get OTAs that improve one pedal driving, radio issues, HVAC issues, updated battery management software, etc.     So age of the vehicle/what GM electrical platform its on will alter what amount of updates can be pushed on OTAs.  
    • Thank You.   So far my new ride is making me look like a genius for going with the 3.0L, as my first fuel refill occurred over three weeks from when I took delivery.  This engine combination is very amazing.  So far no issues and had not done a regen yet.
    • I am curious as to how much fluid you put back in the transmission ( assuming you had replaced the filter to compare to my findings ) and then went through the process of warming up the trans before pulling the check plug to drain out the excess and if you measured how much came back out.    I just found it surprising that some claimed a certain amount less fluid being put in and then draining some back out. The attitude of the truck as per if the surface is level and how the trucks stance is would make quite a difference since the check plug is right at the front of the transmission.
