Dash pad swelling 2018 GMC Sierra


Recommended Posts

Posted

I haven't been able to locate any posts concerning the warping or swelling of the dash pad in the 2018 GMC pick ups. Are any of the other 2018's  experiencing this issue?

Mine  was noticed at 1015 miles and the dealer that sold me the truck said it wasn't the dash pad but rather the in fill section where the defrost vent and sensor for the auto headlights live. The dealer in Slidell La. also stated that he has a lot full of 2018 GMC's with the same dash issue.  They supposedly ordered 3 of these panels and each one looked worse than the first panel. Needless to say when they tried to give me the keys back after having my new truck for a week and a half the panel was raised or buckled so bad you could stack 2 quarters on top of each other and slide them into the opening!  The dealer said"we tried 3 times and we are done with it".   I had them re install my original panel which is raised in front of the drivers and passengers view.

A local dealer graciously looked at the dash  (with prompting from GM)  and said it wasn't the in fill panel but the leather dash pad, and changed same out.  Warping is still there, no as bad as originally but its still there.  The local dealer in Biloxi ,Ms. also stated he has never seen this problem.

GM told the dealer to order another dash and to perform and inspection inside while it was open again. 

Anyone have this issue with a good ending?

I had the same issue with my '16. Dealer offered to rip out the dash to fix the issue. I wisely said "no" as I figured that it would come back to me with numerous rattles etc. Mine changes with the temperature. On some days, it sits almost flat.

Did the warping start when the truck was brand new?  Was it the plastic panel next to the windshield or the actual dash pad?  Mine was evident within the first month.   Dealer is trying to say its a factory attachment location design issue.

Any chance it is moisture related? Does the truck have any "new" musty, wet odors that were not there before? Seems that there are quite a few spots where water gets into the cab, and pretty sure the dash is a hard foam.

Common issue.  Mine was like that day one...though I didn't notice until day two.  I fear their repair causing rattles.

Unless the tech drops something into the opening when the dash is off there really isn't any way a rattle could be caused.  U Tube removing the dash on a 2018 GMC, the dash itself is fairly well secured with screws,  there is 2 hook looking devices that kind of clip the front portion in, that may be the source of the warping.

My lead carpenter has a 2014 GMC , his is warping just not as bad.

Once i figure out how to get pictures to this site I'll post them.

The interior is dry as a popcorn fart- that was one of the first things I looked for was moisture intrusion, not a thing.

GM has a 2nd leather dash and filler panel on the way, we shall see how it turns out.

I have entertained the thought of a GM buy back if they cant get this right, not quite sure how that works.

 

I mentioned this to the selling dealer, I guess that was the wrong thing to say as they wont acknowledge my existence now, no reply to phone calls, e-mails, no a thing.

  GM Corp. isnt any help with this rogue dealer, GM says they just sell the vehicles to the dealers and all they are on the hook for is the factory warranty, and any issues that arise during that period like the dash.  Dealer can crap on you after the sale and they cant or wont do a thing.

Yep, you should have never mentioned that to anyone. Now just for S&G go back and look at the 2007-2013 Avalanche, Suburban, Yukon and Escalade...notorious for cracked dashboards (by the instrument cluster brow and the passenger side airbag) and short of a few people getting new dash boards that later cracked GM didn't do squat so a buy back is probably wishful thinking at best. I do wish you the best of luck ?

Nope haven't had that issue. It's extremely common on the 2015-present F-150's though. The glovebox also tends to warp on them.

Yes.  Same warping!!  I have 2 places on my dash, right of the drivers view and another in front of the passenger view.  Since Mandal GMC in D'iberville Ms. changed the entire padded dash and the plastic panel its not as bad- BUT , maybe i'm gun shy, I have had the pleasure of owning every year model of GM truck that suffered dash failure, and some at an early age.

I was hoping the dash material had surely been changed with the huge outcry of GM owners in the same predicament, but apparently not.   So I am not letting this rest on my brand new truck.  They can fix it or they can have it back.  My older trucks in the fleet look like cold crap, and now my new truck is headed down the same path?     And 2 different dealers are telling 2 different stories??   The selling dealer says he has a lot full of brand new trucks with warping dashes, and the dealer GM Corp. sent me to is saying they have never seen this.   CYA??

My 2016 did it and so does my 2018. I had thought of using some 3m double sided tape to see if that would fix it but decided to just live with it. It's more annoying than anything when they don't fix what they know is wrong and just keep pumping them out.

    • It is possible to add your own 12v outlet to your truck.  Check out this video:   I verified via GM Upfitters that pin 31 is the same on the 1500 trucks.  The wire is GM part number 84779405.   You can get the GM 12v outlet from Amazon  https://www.amazon.com/Genuine-Accessory-Receptacle-25774623-13549530/dp/B0F1H9YRGF EWAY 12 Volt Power Adapter for GM   https://www.amazon.com/EWAY-Chevrolet-Silverado-Cigarette-Ignition/dp/B0915RRW6Q/ref=sr_1_1?   I just haven't figured out a good place to put the 12v outlet in my truck.   Some people are getting USB-C to 12V adapters  https://www.amazon.com/WYMECT-Cigarette-Lighter-Socket-Adapter/dp/B0F87WNQKB/ref=sr_1_1_sspa? Not sure if they provide the correct amperage that a device like a tire inflator would need.  
    • Thanks; I looked there a few minutes, and I think I can find something. I really never looked there, as I thought it was stuff like PTO/aftermarket bodies/accessories like snow plows.
    • This is a 1/2 ton thing ONLY.  All HDs 2020-2026 have the two speed transfer case, with Autotrac as an option.     1/2 tons 2019-2026, regular 4x4s come with a single speed case (no 4LO!), and trucks with Z71 ordered, or all Trail Boss trucks come with the 2 speed case.  2 speed case is also an option on WT, and is also standard on High Country.  
    • 2013 5.3 still to this day calls for the PF48 filter.  Which as a 15psi bypass pressure.     There is a TSB, 17-NA-157 that talks about the PF-63 and PF-64 filters which have a higher bypass rating of 22psi.    TSB HERE - temp.xml   "Beginning in 2012, the oil pumps began to regulate main gallery feedback instead of pump out pressure. This means that the oil pump now does not begin to regulate until pressure is built up to the main gallery. This change reduces the amount of time it takes to provide oil to the engine bearing and lifters during extreme cold start conditions.  Main gallery feedback oil pump control systems are present on the following engine families which use Spin-on oil filters: Small Gas Engine (SGE), Large Gas Engine (LGE), High Feature (HFV6) Gen2 and Small Block Gen5 gasoline engines. These engines with the main gallery feedback oil pump control systems are factory built with an ACDelco® oil filters"   It also calls out what engines use those filters.  The gen 4 small blocks were not on that list (LMG, LC9, L9H, L92, L94, L20, L96).  Gen 5 small blocks use the higher pressure filter.          That all said...   Your 7045 Napa filter is the PF63 equivalent, with 22psi bypass.  You are already using the higher bypass pressure filter.  You CAN keep using it, you don't technically have to use it though.  
    • Do you know WHY the filter relief setting was increased to 22 psig?    When the new system goes into the second stage the pump volume ramps up considerably. It was found that the 15 psi filter bypass setting put the filter in bypass on a warm engine when the second stage was activated. Raising the filter bypass setting forced the filter to do what it designed to do. Filter. Preventing debris from circulating during high load, high rpm operation.    So next question is how did GM find this out? VLOM/lifter failures and a deep dive by Melling Corp.    Last question. Is it required? Look at it like this; a motor may be equipped with a rev limiter. But it only works if the set point in reached. That 22 psig setting only matters if the pressure differential across the filter media exceeds 15 psig during normal warm operation. Second stage kicks in around 3000-3500 rpm.    I can't answer your question because I don't know you and how you use the truck. But I think there is enough information here to let you decide for yourself. 😉
