Vibration Issue on 2016 Yukon Denali XL

I have a 2016 Yukon XL Denali and having two issues that seem to be common among several GM vehicles. Car has 44,,XXX miles so factory warranty is no longer valid even though we have only had the vehicle for a little more than two years.

 

The first is the "Service Driver Assist" warning that appears to be an issue over the past several years on multiple models.  Based on what I have read, it is common that the wires under the driver seat get damaged when the seat is adjusted.  Has anyone had luck getting GM to recognize the faulty design of this system and received assistance getting is fixed.  I have seen it is common to pay as much as  $400 for parts and labor.

 

Also, we are noticing intermittent vibration at various speeds and RPM's.  I have read a variety of posts regarding this issue which is commonly referred to as the "Chevy Shake".  Does anyone know if this is covered under the Powertrain warranty?

 

Any help you can share would be greatly appreciated.  I have spoken with the dealer I purchased the vehicle from regarding the Driver Assist issue and they were no help. 

 

A little disappointed in the reliability of a vehicle that had a sticker price of more than $80,000.

I jut had my 2018 with 3k miles on them balanced twice, one with road force and one without. The second time was with road force and the end result was 10,12,18,22 lbs of road force and GM says that was all within limits. I feel 18,22 is too high but according to GM that is within specs. 

 

Im going to measure my rear axle balance tonight and see what might come out to be before I send it back to the GM service dept

My vehicle has a vibration that seems to be constant despite the road condition (to a degree) or it feels like my suspension is always bouncing up/down like I'm driving on a cobblestone road/rocky road

For me I had the tech rebalance the third set of tires and he said all we're 17lbs RF. At the same time he flushed my transmission with the new fluid. Shudder from transmission is gone and the vibration was near null for 2-3 weeks then it started to come back. I don't think it's transmission and feel it's the tires again. 

 

I'm going to talk to service manager and try to talk my way into getting Michelin defenders. The tech is coaching me into what I should say to promote this request.

 

7k miles and I have had 4 RFB, 3 new tires

I had the same vibration at high speeds (55+). Turns out it was the bridgestone tires. I replaced the tires with Michelin Defenders and the vibration has not returned... Would highly recommend the defenders. I have about 10k miles on them and they've been great.

      Some Assembly is Required

      Common Sense Assembly   Your driveline is forgiving of the occasional mistake. It will even often forgive the random serious blunder. But it will not forgive a continuous bad habit.      What? Not everything needs to be a five thousand word essay.

      Gas Prices

      We drove about 15 minute east today to visit a friend and saw a steep increase in price in the same county. About 50 cents a gallon steepper.

      Wow I'm in a pickle. (Broke down truck) and a story.

      Sure about that? A degree wheel and a dial indicator would lower your degree of assurance in that statement. 😉    It why we have offset keys and dialable timing sprockets. Just say'n.... I've built a few and have never seen one "On the money".

      Tire psi

      By Chuck FB · Posted

      I will admit I haven't experimented much with pressure drops beyond the numbers I put in and part of that is that the numbers I used are fairly low and then found out it would trigger regardless at that 35 psi. Having said that I had tried before had changed the placard pressures and being that I have a 1 ton set to 80 on the placard for the rear I believe it triggered close to 60, the front I don't recall now for sure but thought maybe it could get close to 45 from that factory 60 placard pressure. So I never did figure out if it was a number of psi from placard pressure to the alarm or a percentage of the total placard number as some figured it was like a 25% drop from placard pressure would trigger it. So as to try and answer your question, I believe I set the placard pressure on the front to 47 or so and while I run the front tires at 40, they have dipped below that some if its colder and I haven't put "winter air" in yet and never once have had the front alarm go off. I would say that the answer your looking for is no, that if you set your placard pressure to 45, you have a certain amount of room to drop below that pressure before the alarm will go off.    The pressures you decide to run in your truck, that ends up being what makes sense to you based on what your carrying in your truck or if towing, then have to bump them back up to something that will carry the load in the rear and the fronts typically left at the same pressure. It all comes down to that chart I put the link to and using an accurate roadside scale to be your guide, both unloaded and then loaded to know your minimum safe pressures.    I just wish GM would allow a person to change the readings for the tire pressures to the English system of pounds as I have to look at that goofy metric reading that will never ever jive in my head and will go over and change it just to figure out what they are if need be and then change it back.

      No Software Updates - Old Build

      By TrueBlue · Posted

      That part I understand, that the dealer can do it. But I'm not understanding why updates that were available to the truck since it left the factory, or the dealership originally, would not still be available to it without dealer intervention.   I'm thinking along the lines of recalls. They stay available until they are completed, regardless of whether they are in warranty or not, or in the hands of the original owner or not. Why not updates as well, especially since some of those can be safety related also?
