  1. LT tires, correct? If so, I'd adjust PSI for the load being carried/towed - 80 PSI empty is too high.
  2. When that feature is part of the GPS system it's usually displayed on same screen as Lat/Long...but I haven't even found that screen yet.
  3. best performance parts for 6.2L

    That's a great increase!! Where's the dyno you promised?
  4. I buy a lot of cars and have never seen an "official service record" nor would I know to ask to see one...so who are you worried might see this and create problems on a future sale? Lawyer will cost you money so I'd suggest contact the consumer fraud department of the AG and see what they say. Not sure if you'll get any satisfaction anyway you go. Good luck.
  5. Nope not XM...the message is part of the "vehicle reminder messages" - check the owner's manual. Don't how to turn it off. Here's from the book: ICE POSSIBLE DRIVE WITH CARE This message displays when ice conditions are possible
  6. In Texas 6.25% on the difference between purchase price of new and trade value of old.
  7. I have a 2017 Yukon Denali and I use this case on my iPhone 7 and it wirelessly charges with no issues...so that implies to me that the Qi standard used by GM in 2017 does work. Can't figure out why it doesn't work with the iPhone 8. Maybe I'll take my iPhone 7 and charging case to the dealer and see if it charges on the 2018 version. https://bezalel.co/pages/latitude-universal-charging-case
  8. So is that the part number for the charging module or the console lid with the module in place?
  9. I would think a 2 quart overfill (overfilled by a third!!) would be problematic - personally I'd get it back to the correct fill.
  10. Why "eventually" - do it now.
  11. Interesting that Apple iPhone 8 will charge wirelessly on GM 2018 models but not on 2017 and earlier. So GM did something with the 2018 charge pads - just don't know what. Here's what Apple says: The implementations of wireless charging in 2017 and earlier models from Buick, Cadillac, Chevrolet, and GMC do not meet the requirements for Qi certification. These models do not work with iPhone 8 and iPhone 8 Plus. https://support.apple.com/en-us/HT208148
  12. 2018 Colorado backup display too bright

    The car is new and the screen is as clear as my HD TV in normal light conditions - it's only at night that the screen is washed out. Doubt a brighter reverse bulb will fix this. The GM bulletin fixes something related to screen brightness just not on my car according to the dealer. I'll continue pursuing this. And software can fix hardware issues - happens all the time.

    I have the same issue on a 2017 Yukon Denali. I asked the dealer to apply 17-NA-269 and was told that it didn't apply to my car since I have RSE and that the camera was working as it is supposed to. I'll take it back in one dark morning and show them that the camera is worthless at night - completely washed out.
  14. I have been an XM subscriber for more than 10 years and I have never experienced such poor reception as I do now on a 2017 Yukon Denali. I've had the XM radios on pre-2017 GM vehicles, Porsche, BMW, Lexus and they all worked flawlessly. Not sure how we get this fixed. I'm ready to tell XM that reception is so bad that I'm going to cancel my subscription - maybe Sirius/XM will put pressure on GM to fix (doubt it though). Also, the problem is at GM's end not at XM's - I get signal drop-out on my Yukon in certain areas and then drive the same route, same day and approximate time in my wife's Lexus and no signal disruption.
  15. Thanks for the info...but you didn't tell what is the "best answer for this issue" on 2017 models?
