Found a lawyer and sent the dealership and GM a final attempt to fix letter on my 2014 Sierra. Heard back from GM and they are setting it up with the dealership that I purchased it from. They could not fix it the first three times so I doubt anything will change.

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

Good Luck..... It took me four months from that point. I hope they treat you better than they treated me.

Ok so their are alot of pages here. And reading them makes me very parinoid so i stop reading. My 350 mile 2015 has a shake starting at 73 or 75 and goes a bit above 80. Flat expressway, 3.08 gear 18"s z71 crew. Can be minor or can shake the crap out of my arm rest of the bench, random in its intensity though usually lighter. Feels like in middle or rear of truck little feel in steering wheel. Is this the rear diff shim issue? Is their a bullitin on it to take to the dealer?

How serious are some of yalls issues? Reason I ask is I seem to have a vibration right around the speeds said (69-73mph) and the steering wheel shakes up and down periodically and the passenger seat shakes a bit. Should I take it in and address it with the service dept?

So, I took mine in today. They did a forced balance on all 4 wheels. Here's the vid I took afterwards, absolutely NO difference...

sorry to say, from what I've read here, yes there is. I havn't been on this forum super long, but ive seen multiple people saying they have had their rear diff's rebuilt/ replaced for vibration issues

that sucks man, mine isn't that bad, but it still miserable to be dealing with either way. try to get them to look at some of the things previously mentioned (driveshaft, rear diff, engine for excessive AFM shake, wheels and rims for proper roundness - not just rebalancing)

hope something works for ya

Mine has been at the dealer for 3 days now. shakes just like in the vid above mostly between 70 and 75. they checked the wheels said they were all within spec but they went ahead and re balanced them anyway. they test drove it and said problem was still there. next they swapped out the rims and tires with another truck and problem still existed. then they rotated those new wheels and tires still no difference. technician took another truck for a test drive and said it did the same thing and that it must be normal for these trucks.

 

service adviser is waiting on the service manager to make a decision on what to do next. i really like my truck hope it gets fixed.

Can others take some video's and post them here?

 

I'd like to use it as supporting documentation. You can never have too much info when dealing with the dealerships, and showing this is not necessarily an isolated case may be helpful.

don't take normal as acceptable answer its not normal its a huge issue GM has.

 

Has anyone dealt with a GM field engineer? I have one coming next week to look at my truck.

So we got our 2014 rally 2 back after the final repair attempt with GM engineers. Unfortunately the problem is not resolved. They road forced the tires again and two were replaced which did not fix the issue. Here are some videos for you all that we've taken. The first one is our truck before the final repair attempt. The second video is a loaner they gave us. The third video is our truck after we got it back from the dealer. Have to say we are super disappointed. We love our truck so much :(

We just got ours back from being with the GM engineers, they hooked up the PICO meter and drove it about 50 miles. They just changed out two tires. BUT our dealer has already road forced the originals tires, then changed out all four, after that they rebuilt the deferential and changed out the drive shaft. So they kind of did what they could already. Just really sucks :/ our dealership has been AMAZING to say the least and we are SO thankful they've stuck with us through all this. See my above videos for some reference.

      Video processing module location

      By twgraham · Posted

      Can someone tell me where the video processing module is in a 2023 Silverado? I'm getting conflicting results that it's in the front passenger area or the rear passenger area behind the seat.

      Missing thrust bearing? And oil selection

      By Chuck FB · Posted

      Yes I agree, its what amounts to free advertising to let people know about his UOA testing company, and not that there is anything wrong with that but certainly that is a motivator for putting out videos about the science of oil as well as other topics such as oil and air filtration etc. The interesting part I found with his last video is not only the physics behind the reason for the varying wear due to a diesels working torque range causing more bearing load and that higher viscosity oil is of benefit, it was also that the chemistry behind the GM Dexos 0W-20 and the Mobil Dexos licensed 0W-20 are far enough apart that its showing up with a difference in wear even though the two oils are matched in viscosity and in that comparison viscosity was not having the finger pointed at it.    There are a few youtubers out there or one anyway that I have watched a bit of who has gone through the pains of accessing various countries manuals for a certain engine platform and while in the US/Canada it may say use 0W-20 or what have you for some Toyota product, in some other countries it sings a very different tune for the very same engine with the typical traditional oil viscosity/ambient temperature charts to help choose which oil viscosity is correct for the conditions the vehicle will be used in and in some cases its taken an engine in a US manual that states only use 0W-20 as per warranty coverage and yet that same engine in certain other countries may have up to a 15W-40 etc oil option that meets the spec. Another words the guy who is driving through Death Valley or Phoenix and south weather at 120f is often being fed a line of bs by the US system that has forced vehicle companies to restrict the warranty to a specific low viscosity oil for anterior reasons as well as the long drain interval suggestions.    Thankfully youtube is free ( yet anyway ) for viewers to sift through information and of course comes with the good and the bad ( truth and lies ) and we can choose to turn off/not watch what a person finds is bs or just not interested in the topic.

      No doubt... But, as someone who doesn't pay for his services, but who has provided a few views/clicks on his Youtube platform, the data around the Mobil oil testing I think does have some value including to "freeloaders" like me.   A lot of what he's doing is likely showing the OE's work in their oil selection, something that many of us had kind of assumed was true all along, a good balance of both excellent protection and efficiency.

      Lake Speed is drumming up business for his company just by being in the spot-light so he has a vested interest in stoking the 0W-20 fire.  IMO

      summer road trips in the 2026 2500HD

      By Chuck FB · Posted

      I knew when I bought my truck that it had off road hill decent or craw control or whatever they call it and rolled my eyes at that but it gets throw on with other options my truck has, I just never had a heads up if the highway speed regular cruise setting had anything to do with the brakes and that took me by surprise. If you've ever been to the top of Pikes Peak and watched those ahead of you on the way down with their brake lights on constantly, one can guess they are probably not gearing down or not enough anyway if their vehicle will allow and a good reason their is a brake check spot part way down where they use an infra red heat gun to check how hot ones brakes are front and rear.    Your right that once one gets out of the front range by Denver and I've not been on that stretch of 285 between Denver and Fairplay myself but I know its high and Fairplay at 10000 feet, Buena Vista at 8000, it drops a bit from there but then your going back up and over the 11000 pass and Durango is at 6500 . So yes your definitely right that 6500 and a lot higher is the theme of going anywhere out in that direction from Denver but hey, the down hill sections give fantastic fuel mileage !.    I don't even look at the fuel pumps for what premium costs here, since I live on a farm and up to this point get fuel delivered I am rarely in front of a fuel pump and when I am, I am often using card lock bulk fuel stations so it tells me what the price is AFTER I buy the fuel. Looking up on gas buddy and converting to US gallons but in Canadian dollars, regular on average of the prices listed was around 5.95 and premium is around 7.00 . That was one reason I did not go for the 6.2 half ton aside from its lack of carrying/towing if one was going by the rule of using premium fuel and until recently one could only buy regular farm gas if playing the few cents off game for farm dyed fuel for a "farm licensed pickup". But yes I hear you on the fuel price difference and like the diesel theme with it often being more expensive then gas it doesn't have quite the charm to it either as it once did although right now here for some reason the price of diesel has come down more so its now inline with the price of regular gas.
