  1. I had a similar problem the first week, same truck with 22's. I brought it back to the dealer with a couple hundred miles on it. They found 1 tire out of round and road forced the rest. After they swapped out the tire and balanced it's been great. I will say that it does smooth out over time also. I went and bought new OEM 20" wheels for snow tires and went through 2 different sets of snows and could not get them to stop shaking over 60mph. Went back 5 different times for different types of balance techniques and in the end took them off and put the stock 22's back on!
  2. Got the call back today that after all the testing with the specialized equipment, GM says there is a bulletin out that extends to the 2019 GMC Sierra 1500 that as the DFM does it's thing, there may be a vibration felt in the floor, seat, steering wheel, etc. there is no service recommenced! So with 2900 miles on it, and $62K i'm supposed to live with the stupid vibrations. They claim that there is no vibrations when the truck is in manual shift mode and that is the proof that the vibrations are caused by the DFM.... Am I being jerked around, or is this what I am supposed to live with on this truck? Is there a place to see all the service bulletins online? I'm pissed that I have a great truck that rides like shit!
  3. They replaced the bad tire and there is still a problem. I had to take the service manager for a ride today, he is not thinking it's a wheel/tire issue as it vibrates through all speed ranges. I left it with them again. Not happy, brand new truck, 2900 miles, WTF
  4. They are replacing one bad tire and then we'll see from there. They have had it for half a day, we'll see what today brings.......
  5. Grab it by the bottom of the arrow and pull a bow into the piece, the point of the arrow is where the tab is located. It needs to slide rearward to dis engage. Put your hand on the part with the tab and hold it in while you pull with the other hand and it will slide out
  6. My 19 Denali Ultimate (2000 mi, 3 weeks old) was back to the dealer for a vibration, they are getting me a loaner next week. They need to swap out tires, they claim they have had issues with the 22" tires being defective. The vibration is not bad (not as bad as my 14 HC) on the highway, but when hitting bumps the truck seems to chatter pretty good. We'll see what they come up with.....
  7. So I did my install the other day, pretty straighforward following the directions on the website. One thing the directions say is "Be careful not to break the tab" blah blah. So I broke the damn tab on the drivers side, not really noticeable as I didn't break it all the way off, it was hanging by a thread but enough to hold it in place. The trick here is to grab the middle of the lower trim piece and pull it out (bend it) towards you to slide the tab out of the front. You need to release all the clips first, but put some decent pressure on the middle while holding the front part in (make a bow in it) and it will come out. Other than that the directions were spot on. Good luck
  8. I had a convo with him on FB, GM made him take it down. I got mine sitting here waiting to install, looks like i'll do it from memory too!
  9. Put on the FAC G4 cover today! Fits mint, i really like it. Also put in the Pop and Lock power tailgate lock. I still can't believe i had to buy it aftermarket, i came from an Avalanche where it is standard equip! Here's a few pics, only 156 miles on it!
  10. I was thinking this when i hit the flapper and it started right up, that it made no sense that the flapper was the cause. So now i'm waiting for it to happen again.... maybe it is the starter, guess i won't know until it shows its ugly head again!
  11. Ok, left the truck at the dealer overnite outside (4 degrees), got there at 7am, hit the remote start and she fired right up! The service guy said they bolted the butterfly in the flapper valve in the open position per GM engineering. This is a temporary fix until a permanent fix can be found, also per GM engineering. I am hoping this takes care of that problem, although i still don't understand how that flapper could be the cause of the truck not starting. There are no wires to the flapper nor could i see any sensor? The truck never turned over at all, so how does the engine know not to start from a mechanical butterfly valve so far away from the engine? When i went to start it there was a click (not a starter type click) coming from under the dash area and then the cluster went black. Just don't see how the thing works. Any insight on that thing? Anyway i'm glad to have the truck back, and hopefully with no further problems! Kevin
  12. Really? a hammer fixed it? we never heard of this problem? we'll investigate it while we install your bed mat and give you an inspection sticker. I made them keep the truck overnite and i will meet them first thing in the morning to start the truck. It is being left outside tonite and it is going to be 2 degrees in the am. We'll see if it starts..... I'll post back with any progress tomorrow
  13. The starter never engaged, there was a quick click inside the passenger compartment, maybe behind the dash and then black screen.
  14. My truck is new(79 Miles on it) got it yesterday, today 0 degrees, would not start. Got out the hammer and wrapped on the exhaust and it started. There is some kind of exhaust flap i read about here that has been causing issues! On my way back to the dealer now! Not Happy
