I am still pretty surprised how long this thread has gone on and still nobody has taken their truck to a driveline shop to at least have the driveshaft and yokes inspected to have the opinion of a third party expert on the matter. I was in the same boat with my first truck though and was hoping they could fix it but they never could and wound up buying it back. They checked every spec in the rear end and it was all within tolerance but one thing they didn't do was the shaft. We could kill a few birds with one stone per se on whether it could be could the balance, yokes not welded on straight, or the aluminum shaft debate about it warping etc. As stated before I would volunteer mine but I have already been down the path of having my truck torn completely apart before the buyback and am trying to avoid it with the new one until I can pinpoint the issue. Thanks in advance to anyone who has theirs checked and reports back; if nobody does in the near future I might go ahead and do so. Hopefully we can fix it or rule it out completely!

How many miles did you have on yours when they bought it back? Ive officially requested a buyback today from GM and from the dealership owner. Awaiting to hear the verdict. Why did you go with another sierra? I told them I would consider buying some other GM vehicle but most likely not another sierra, silverado or anything else that shares drivetrain parts with these trucks. I don't want to be back in the same boat in a few thousand miles.

I hear ya there. They bought mine back at 7k miles and honestly my thought was "what are the chances I would get 2 bad ones?" Well apparently the chances are 100%. I have a boat and the only other GM that would have done the job was the Yukon which I didn't want to spend the nearly 20k difference in price. I test drove the new one for a week though before I signed the papers and it seemed fine and since then it has shown up. Tires are all really low road force and not the goodyears so I am not sure what would have mechanically changed from then and now. That being said, from what I hear, a driveshaft vibration is more of a high frequency and what I'm experiencing feels like a tire out of balance even though I know it's not (according to 3 different road force machines). Only have the rear vibration in seats and console, steering wheel is smooth as can be.

I just joined the community after reading about all the vibration issues with the 2014 trucks. I also have a strange vibration in mine but not like a lot have described (at speeds 70-80mph). Mine shutters very hard when slowing down starting at about 40mph all the way to 5mph and not like a brake pulse or tires that u would feel while constantly braking or driving. I took it to my dealer that kept it for about a week and they came to the conclusion that it needed a drive shaft. So they ordered one and put it in and there is no difference. It still does it and it's getting worse, so bad that it's making things under the dash rattle. Now I did have a pair of leveling shackles on it but was told by my dealer that that's what was causing it so I took them off and it's still the same. I'm trying to find another dealership to go to to get it looked at after the last time I went to my current dealer to get my oil changed and tires rotated and they scratched my bumper and left huge greasy hand prints in and out of the truck. I have realized while slowing down I can put the truck in neutral and it will not vibrate! Hopefully when I find another GOOD dealer they can figure this out. Anyone else having this issue? Mine is a 2014 sierra sle single cab short bed 2wd.

That is my issue also (no high speed vibes of significance). My '14 Silverado, regular cab, short bed, Z71, 2WD, V8 shudders VERY OBVIOUSLY when slowing down between 32 and 18 MPH. It does not shudder if I put it in Neutral while decelerating. I have eliminated V4 mode and tires/wheels/brakes as likely causes. I think it is either the torque converter remaining locked-up too long or something in the transmission. It is felt in the steering wheel and throughout the entire cab. I have not taken it to the dealer yet for a variety of reasons. With less than 800 miles, it seems like a great truck otherwise but I am very disappointed in the unacceptable vibes in a $37,000 new truck...!

There is steering wheel and seat vibration, I wonder if Im now just hyper sensitive to every little bump and if it actually is normal. I would love to drive somebodies truck that says its "smooth as glass"

I've wondered the same thing and wish some of us could drive each other's trucks and compare. I think it is a possibility we're sensitive after reading this thread. Thinking back to my 2007, my passenger seat and console would shake while driving. The seat was so bad it would squeak and drive me nuts! The dealer fixed the squeak but the seat still vibrated especially over bumps. I just don't remember feeling much in the steering wheel itself but again we're talking hydraulic power steering versus electric power steering. Electric definitely has a different feel to it overall so I don't know if that's affecting things or not.

I felt the vibration from day 1. I then googled "2014 Silverado vibration". This thread popped up so I'm not sensitive because of this thread. VIBRATION IS NOT A NORMAL CHARACTERISTIC FOR ANY VEHICLE!!!

It sounds like some guys are willing to accept this as normal. I understand some of you are diehard GM guys and are willing to pay to have driveshafts balanced or buy new tires but maybe it is time you take it to the next level. Laws are in place to protect you from this nonsense.

These sound like totally different issues. For all of the problems with mine it stops on a dime with no shudder.

 

I would first say warped discs but if it goes away when in neutral you may be looking at a transmission issue.

Did you read the post I was responding to above (Post #1596)? Same symptoms! And I have established, as noted in my post, that brakes are not the cause since...it vibrates the same when coasting to a stop.

I have been going through the buyback process and its been 7 weeks already. Still no new truck. They were shipping one from SC to NJ supposedly but that was last Wednesday no updates since them other than an email saying sorry no updates yet

Well it's official: my truck vibrates. And it does get worse with the heat. I guess it's not really the tires. I just got back from a trip for work today driving 1 hour to the destination and one hour back and it definitely was not a comfortable ride. It does seem to be mostly in the steering wheel as the truck feels fine when you take your hands off the wheel. Anyway I guess it's time to start the drawn out process of going to the dealer a thousand times for them to throw parts at it. The truck only has 3000 miles on it. I'm really kicking myself for not listening to my gut and buying a Toyota......

It's a constant vibration/shimmy in the steering wheel at all speeds. Something isn't right in the front end. Either ball joints or the tie rod or I dunno what but I'm definitely calling the dealer tomorrow to make an appointment.

Maybe the front driveshaft

Yes especially since you quoted it and they are right next to each other. I was reffering to both of of them, you are BOTH having problems nobody else in this entire thread is having and I have read it all. Nobody said brakes either discs/rotors are not brakes.

OK, thanks for enlightening me about discs/rotors not being part of the brake system.

Ok so I travel weekly about 8 hrs each way for work, I have 15,800 miles on mine. I have also spent a chunk of money on a new set of American Force wheels which are custom CNC machined made to be true. New set of tires and to this date I have the worst vibration I have ever felt on any vehicle in my life. I spent almost 50 grand and I feel as If I got crap for it. It's going in tomorrow. BTW this will be the second truck Chevy has given me for defects. If they can't fix this, I'm just getting my money back. This should be added to the recall GM has going!

    • Apologies in advance, this is a long post, there's a lot to explain.   A friend had a 2010 Avalanche with a 5.3 (LMG) that blew the head gaskets (amount other problems). He gave me a donor motor out of a 2007 suburban (LC9). I got it all installed, and everything hooked up. Went to go start it, and it stumbled a bit at first and died a couple times, but after trying a few times it sounded like it was running very well. Went out to go get some coolant, and came back the next day.    Upon trying to start it, the truck will crank and fire normally and the RPMs will raise to around 1,200 or 1,500, sounding great, and then the RPMs will decrease and it will just die. Repeat that a dozen or two dozen times, and eventually it will fire and idle beautifully. As soon as you touch the throttle, it will start misfiring and sound like absolute trash. When you let off the throttle it will come down and hunt around shaking and misfiring like crazy. A message will come up on the dash saying reduced engine power.    It is throwing codes for a map sensor circuit voltage High, as well as MAF sensor low frequency. With key on engine off, the map sensor reads about 4.8 volts on the vout pin, which the PCM interprets as about 17.8 PSI, contrasted to the barometer which my scan tool tells me reads about 13.5 PSI. However, once the engine starts and is idling this reading drops to about 5-6 PSI at a stable idle, and varies significantly when the engine is misfiring/ hunting like I said before. I should note that I used the intake and MAP sensor from the LC9 engine. I changed the connector on the 2010 harness to The 2007 connector. The pinouts for the sensors were printed right on the top, and I triple-checked that I put the correct wire into the correct place.   On the other hand, the MAF sensor reads consistently 0.0 g/s regardless of State. I have pulled my hair out trying to figure out this last detail. I have tried three different sensors, (all of which should be good, one of which was new), I have verified all the wiring from the sensor going back to the PCM, and have verified that the readings at the PCM are the same readings as at the sensor itself. The intake air temperature sensor is also functioning as normal. I verified all the voltages and grounds etc, and everything is as it should be. I don't have an oscilloscope to verify, but I probed with my multimeter (Klein mm720) on frequency Mode, and it reads that on initial cranking, the maf is producing between 3000 and 7000 HZ, and as soon as the engine fires that falls off to below, 1000, and if the engine continues to run, it will produce somewhat erratic readings between 5 and 100-200 HZ. It does increase notably when the engine is revved despite the misfirings. As I said before, I have verified all of the wires going to the PCM, and I have tried multiple known good sensors. I've tested all the pins and voltages from the sensor and verified them against the manual that they are what they should be. I tested all the wiring for both ohms and voltage drop, and everything tested fine. Like I said I tested at the sensor as well as right at the PCM, everything checked out.   The only other thing of note at least I think is the fact that the engine originally in the truck had VVT, but the engine I put in, the lc9, does not have VVT. I modified the cam sensor plug to work. I reference the wiring diagrams and double-checked that I modified the harness correctly to adapt it. There is obviously a code for the VVT solenoid, but I don't think that's the cause of my problems, and this friend will probably have the PCM sent off to tune out the codes at some point.   I'm writing this for my bed so I don't recall the exact codes, but I'll update the post tomorrow morning with the exact codes. And ideas or feedback much appreciated. 
    • It's possible the two trucks are using different body control modules which is why yours works and the OP's doesn't.   So much in these newer vehicles depends on model/trim configurations, production date. They don't all use the same modules like back in the day.
    • I forgot to answer the question as per what market mine is set to and yes I finally found that area on mine and yes its also set to America.   So here's something I realized as I wasn't looking at that part in the Sierra section until now, your right that what I see here as choice 3 under Sierra which says 07/2023-06/2026 ( 433 MHz 13542523 ) it has no choice 5 for tire pressure selection. Where as it does under the Chev choice. However I kept going down the list within the Sierra and I am really wondering if choice 9 will work for your truck as it has the same model number and hertz sensor as my truck. I would say try that choice first, if that doesn't work then jump over to the Chev section and again choose that same model and hertz choice as for some reason the Chev section gives the choice 5 of tire type/pressure selection for going back a number of years. Could very well be an Autel thing that they just didn't get the updates all done properly under Sierra but anyway first try that selection 9 I suggested under Sierra and then go from there. 
    • Looking for this piece that holds the hose clamp in place. I have the hose clamp just not that other piece. Dealers and wrecking yards in my area will not sell just that piece. They want you to buy the whole air tube $100 +/- to get that $5 part.  that piece isn't molded to the air tube as I looked at my friends truck. It's held on by a screw and nut. I'm trying to put the OEM parts on the truck as the previous owner butchered things up installing an aftermarket CAI. It really looked homemade. 🤣 Thanks
    • Ok I missed that part that yours is a GM. The strange part is that the choice for year ranges and within the year of 2026 is different on the Sierra then on the Chev for some reason as I am looking at my tool at the Sierra choices. Now I am guessing you see as to your sensor part number as it may be different on your truck for some reason and a call to GM should get you the part model number of the sensors you should have as well as which MHz your sensors are. I know mine are the ones as per what I listed but there are other choices in the Autel and got me wondering if by some chance they put different ones in your truck. Having said that, did you try using each of the choices starting from No 1 and going on down the list, not sure if that would mean shutting off the engine each time and resetting the tool and going at it again each time. Also I thought of something else which may sound retarded but if there was some stupid chance that the chev choice would work. The reason I say that is that the Sierra is showing a range up to 06/2026 for the various choices of sensors it could be where as the Chev has one choice that has that 12/2026. By the way it is possible to not run the truck and you may know that as per not pressing the brake but pressing and holding the start button for a few seconds and it lights up the dash ( its called service mode ) but that sucks battery power and if it were me doing it that way I would be throwing on a decent sized battery charger before doing it that way as killing your battery won't make you happy at me at all !.    Like I say, just a thought to try the Chev choices if you have already exhausted the Sierra choices but first it would be nice to know for sure what exact sensor model and hertz your truck uses as I assume only those choices that mention the sensor would work unless a choice that does not mention the sensor model would somehow work. Its frustrating when one is trying to use tools like this without the experience of the tool and the vehicle, as I am sure dealer techs themselves struggle with it when starting out or a new model year comes along that is slightly different.
