  1. Good luck. They don’t care. All they will do is provide lip service for a while until they tell you nothing is wrong but you. I can’t even ride in mine without a pressure noise hurting my head. Complained about it within a hundred miles of owning a new 2019 Yukon Denali Ultimate 4x4 and after months of back and forth they said it is performing as designed. So designed to be shitty and will be my last GM.
  2. I’ve been buying GMC’s for years. My first was a 1990 Sierra GT stepside regular cab. Since then I’ve purchased a new/used GM about every 2 to 3 years and in the last several years they have been brand new 4x4 Denali’s from 1500’s to 2500 Duramax’s to the recent Yukon Denali Ultimate. The Yukon has been making a pressure in ways that hurts my ears every time I drive it for a long distance. This is a design flaw and I’m pretty sure it’s because the roof and other sheet metal is thin as paper. I took mine to the dealership a few times and honestly there’s nothing they can do about it. It does seem like the more expensive ones with the 22 inch rims and the sunroof do it worse because there’s less braces in the roof combined with a stiffer ride. Even though it sounds and feels like a vacuum, it does it even at low speed’s and/or with the windows down so it’s more likely a result of internal pressure from the distortion of the cab from the metal flexing. We purchased this 2019 Yukon Denali Ultimate 4x4 because of all my good experiences with previous products from GM but this will absolutely be my last GM SUV. We didn’t find this issue within a couple hundred miles (A few days) of owning the vehicle and GM will not do anything. Finally heard back from GM today and they said that it is normal operation for it to make that pressure noise. So great every time me and my wife drive the Yukon Denali Ultimate 4x4 we get a headache and they say that’s normal operation. I would’ve more than happily traded this vehicle in on a new 2020 Sierra Denali or AT4 but they will not even consider that, so I told them if that’s normal design and there’s nothing they want to do to help out or address the issue then I will not be buying another GM even though I buy a new vehicle about every two years... big surprise they did not care. So I’ll keep this vehicle for my normal two years and then I am done with GM SUVs because obviously loyalty means nothing to them and I’m just a small drop in the bucket. I’m really disappointed because all of the other vehicles have been great and this particular vehicle had an issue and they want to ignore it even though we have almost 400 pages of complaints on this topic on this single forum. I’m not saying I will go to Ford or Dodge but I also have a 5 year old Mercedes for 4 years with zero problems (Usually a one year old Mercedes is close to the same price as the new high-end GMC). ...and I just want to be clear that the dealership has been great it’s GM who’s been horrible.

  4. Yea I think you are right. Even on the Z71 it is JHD.
  5. That sounds similar but different. It sounds like grade braking since it mentions “gears” because hill decent just modulates individual brake calipers. This sounds like when descending a mountain or hill at normal speeds it will keep the vehicle from speeding up (I forgot what this was called but I remember it activates after tapping the brake twice or something like that). Does anyone know of a Z71 RPO that specifies “hill decent”. I will see what mine says.
  6. Grade breaking is not the same as hill decent but they may share some of the same features. I stoped this mod as I am trying to get a buy back because of the cabin pressure issue.
  7. Brighter they are the faster they burn out. These are very a good combination of brightness and longevity.
  8. If you switch the whole thing it is ok but the taillights and sides (including where the tail lights mount) are different. May not match the lines of rest of the truck though
  9. Rockers are bad for the price they want to replace the rockers I can get a low mileage 4.8 From an express van but does anyone know if they will fit. Have a 08 Sierra And wanting to go with a 2010 engine that has the VVT. I think the VVT is all mechanical, So just worried about motor mounts and what not.
  10. I’m actually looking at adding a 88-98 step side on my 07 Sierra regular cab SWB but checking the measurements first. It needs a paint job so now is the time to do it
  11. In contact with GM about a buy back. I have purchased 4 new high end GMC Trucks/SUVs since 2014, a new one in 07 which I still own and a few used ones from GM dealers in between. How this is handled by GM will denote if I purchase any more.
  12. When putting the new lights in the housings, I put the bolt treads the same number/length so the beam pattern was the same. Checked on the wall and they are even.
  13. Yes this is a design flaw and I’m pretty sure it’s because the roof sheet metal is thin as paper. I took mine to the dealership a few times and honestly there’s nothing they can do about it. I test drove a few more and they all do the exact same thing. It does seem like the more expensive ones with the 22 inch rims and the sunroof do it worse because there’s less braces in the roof combined with a stiffer ride. Even though it sounds and feels like a vacuum, it does it even at low speed’s and/or with the windows down so it’s more likely a result of internal pressure from the distortion of the cab from the metal flexing. We purchased this 2019 Yukon Denali Ultimate 4x4 because of all my good experiences with previous products from GM but this will absolutely be my last GM SUV and we’re already looking for something else to trade it in on and I do not even have 1,000 miles on it or have even made the first payment. I had the body style before this and it was great but GM keeps trying to save money and get cheaper and in doing so cut corners so they’re going to continually get crappier. I’m probably going to call GM and file a complaint to see if they will buy it back but I really doubt they will.
  14. I don’t see why they would not be able to. The vehicle already has the information for the degrees of center. I guess we need a technician to comment. I know my 2007 did not come with cruise control and I had them program it in after I added the parts.
