  1. The article linked over to Fox News. Fullsize GM SUVs have a problem that's making owners sick http://www.foxnews.com/leisure/2015/12/31/fullsize-gm-suvs-have-problem-that-making-owners-sick/
  2. Just had mine fixed. Sounds like a problem that carried over from the Acadia. Dealer replaced bearings and seals in steering column and click went away.
  3. So... May be a dumb question but do you guys think putting bigger wheels and tires can make it worse if you believe it's tied to the rear end problems? I went from factory SlT 20s to a 22 with a 305/40 and it seems the rear end rumble under load and corresponding ear pressure is much worse. Thoughts?
  4. My GPS antenna was dead when I test drove it. Same problem you are having. Bad thing is they have to rip the dash out to run the new antenna and cable. Some people have had leaks from the new one. I haven't but they are on their forth try at installing the dash back without scratching or damaging the parts.
  5. While waiting on my new SLT to be prepped, they gave me a Sierra Denali to drive. It's a 15 model and I think they wanted me to trade my tundra. Not going to happen. Wow.. The pressure and buffetting was tremendous. My head was about to explode after 10 mins of driving. Had to drive with windows down just to stand it. After 4 hours I was still hurting with ear and head aches. What's common? AFM and the noise canceling is all I can figure. As soon as I take delivery of the yukon I am going to try the fuse pull to get rid of the last bit of pressure sensation. It is no where near what I feel in this Sierra. Craziness. I'm also going to talk to service tech to see if they can turn it off in the ECU diagnostics tool. Anyone checked on this?
  6. Well I drove another SLT tonight that seems to be the best one yet. I think I'm going to buy it. I played with the rear hatch bumpers half way out to create softer seal against between the door and body. That seemed to help a small bit. I will try full out tomorrow when I take the wife back to drive it. BTW I did go to the doc yesterday and found that I already had a ton of fluid on my inner ears due to a virus. That will make me more sensitive to it than others (same reason they tell you not to fly with a head cold). The v4 mode change wasn't as prevalent in this one compared to the others. If we buy it I'll try the fuse pull and see if it works on an SLT. For now the pressure that I do feel isn't uncomfortable or making my head explode like the first one I drove.
  7. I haven't confirmed if the SLT has the same noise cancellation as the Denali. Do you know? I did read something about a specially valves exhaust to reduce noise on both. This sounded suspect.
  8. Just drove another one. Early model 2wd Denali with the 6 spd. Wife drove it this time. I could feel the pressure but no headache this time. Wife could feel it too but it didn't bother her. I could most definitely feel it when it switched to V4. I'm probably overly sensitive to it since I am congested already. Just more data.
  9. So for folks that have the pressure, headaches and dizzy spells, how long did it last after getting out of the vehicles?
  10. Been following this thread for a while since we wanted to buy a new Yukon. Finally found a 2015.5 today in the config we wanted. Drove it and not sure if I'm experiencing what you guys have noted. No noise or "window down" sound but I was feeling the pressure in my ears and a headache after driving for about 20 mins. I decided to wait and think on it. Weird thing is after being home for a few hours I still feel like my ears need to pop. I may have a simple sinus congestion since a front moved through today. Wish I could discern the real issue. This one was built in November. SLT 2wd.
