Add me to the list of shakers. Live in rural Iowa but just took it to Califonria, as soon as I hit the interstate above 75 the vibration started. I still had 3500 miles to go! The worst was at 82. Took it to the dealer today. They told me they had to wait to hear from GM??

Ok guys, i finally got the problem fixed after several visits to the dealership. The vibration problem is the ring gear and pinion gear which i suspected in the beginning . Chevrolet had an issue with

Had my truck in for the 2nd time today and they tightened up body bolts, checked complete front end, box and exhaust system. They test drove it and still vibrates steering wheel starting at about 50 M

So got my truck back yesterday. Diagnosis: there weren't any wheel weights on any of the tires. Guess they forgot to balance the tires at the factory. So for now, vibration and shaking is unnotice

Update,

 

Received my truck back from the dealership last week Friday with half the problem resolved. Dealership put almost 300 miles of testing within 20+ days of them working on it. GM engineer found the exhaust manifold was causing the vibration issue. They replaced the parts and now I am vibration free as long as I am driving in 6 cylinders. The moment it goes into 4 cylinders the vibration is back at the specific speeds of complaints. Dealership says that GM knows this is an issue and is working on a resolution but he does not have a time frame for the fix. I asked if they can disable the feature and he said that it’s a possible solution but cannot disable it until GM makes it official. I will update the post when I get a resolution for the 4 cylinder issue or if the vibration comes back in 6 cylinder mode.

Well, I had mentioned that I was done dealing with all of GM's BullSh*t, particularly after they told me that it was "normal operation" and they they wouldn't do anything. The lawfirm I had contacted called me back today, and they ARE interested in taking the class action case, they have already gotten some "experts" to look into ALL of the issues, I gave them a little more information, and they said that either one of their "upper level partners" or the "experts" will be contacting me in the next few weeks regarding the overall case.



Here we go, the ball is finally rolling

I finally found another dealership that is willing to really look at the truck. I have a GMC but taking it to a Chevy dealer that's 50 miles away. The Service Advisor was very quick to acknowledge that there are issues with the 2014s. I think I'm going to use this thread and make a checklist of all the things to look at. LOL. I drop off the truck tomorrow night.

 

I'm kind of curious to see how many other people following this thread have the 5.3 8cyl and are experiencing the same vibration issue.

I have a 5.3, but currently have a v6 for a loaner. The AFM vibe that comes from the v6 is entirely different than the vibe I get on my 5.3. The AFM vibe on the v6 is in the steering wheel and column. The vibe on my 5.3 appears to be coming from the rear of the truck and causing the center console to shake at 40mph and 75-80mph. The steering wheel on the 5.3 is solid in and out of AFM (for me anyway). The only thing I can feel is a slight surge when going into and out of AFM on the 5.3.

I have the same vibe but from 70-80. Have you noticed the vibe to be much worse during colder weather? Where I'm at the temp swings 35 degrees from when I go to work to when I come home, vibration is less severe in the afternoon .

      Gas Prices

      By Chuck FB · Posted

      Interesting, I suspect I would have fueled up in Lee Vining as the day prior I would have filled up either in Laughlin or near there and maybe again before I entered Death Valley and once out the other side late that evening as I kept on driving into the night up near Lee Vining. Next morning I most likely fueled up in LV before heading over Tioga Pass into ( as I refer to it as "Yose .... Mite" 😁 ). And again that was 19 years ago but the price then must not have jumped out at me like the 5 bill a gallon theme of nutty cult hippy country Big Sir or head so far up their rear Aspen. I'd be curious to know where the highest prices are in the lower 48, I probably would not be far off to guess somewhere in Cali forn ie. Coldfoot and Prudhoe bay may have those prices beat but that is a whole other world up there and when prices are more normal elsewhere that is about what they can be up there I believe in no mans land. Anyway interesting that the 395 corridor is hosing people and the thing is, its tourist season and its not like there are a lot of competition options when driving up that highway from what I could see. Yup, big ole Boaterhomes and various other RV's ahead and behind me at the Yosemite entrance gate and they have to get their fuel somewhere.

      Those can be high, as well as the big California cities. The ones that will pop your eyes out are the 395 corridor on the Eastern side of the Sierra Nevadas. Lee Vining, $7.19 for regular and $8.89 for diesel is what the Google said right now.

      Correct.  2019-2021 model years are serviced by a different p/n.  19420611.  Recall 2021s use 19420611.   The recall engines 2022-2024 model years are serviced with 12740076.     The difference between 19420611 and 12740076 is GM changed injector size for 2022.  The injectors are smaller on 12740076 with smaller injector bores in the cylinder heads to match the smaller injectors.  So you can't install a 19420611 in a 2022-2024, and you can't install a 12740076 in a 2019-2021.     Both engines are the replacement engine p/ns that are in the L87 recall.  So both of these are the updated engines.     Here's a version of the L87 recall with the p/ns for all the parts needed.    RCRIT-25V274-7075.pdf   Note it shows 19420611 and 12740076 with an asterisk to a footnote "Use the VIN and the GM Electronic Parts Catalog (EPC) to determine which part to order if two or more part numbers are listed for the same part, as it may vary by vehicle options."

      2020 Trailboss 6.2 replacement

      By 2017Z · Posted

      Looking for advice from this group. Took my flawless 2020 6.2 TB to an unnamed shop for routine rear brakes and oil change. Tech forgot to put oil back in after the full service and needles to say, destroyed my engine.  It’s all on their shop video so they are responsible.   I had my Chevy dealer do the analysis and they confirmed its compromised and said engine replacement. The manager said they only get GM reman engines from GM with full 3 yr warranty and the one they would put in is not same as what’s they are swapping out on 21-25 for recall.    I am looking for advice why that would be a different engine because obviously I had the good 6.2 year and replacing it has my concerns with that recall for 21-15   Also what’s the pros and cons of accepting the engine swap vs telling the shop that bricked the truck to pay up so I buy a new truck. I’m concerned about stigma resale eventually if I just decide to get rid of it after the swap or other issues showing up after the swap out.
