  1. Redwngr, I will look again, but mine is one of the early 2015s and may need an ECM reprogram in order to get it. I will look tomorrow to see if it is there Sent from my iPad using Tapatalk
  2. I do not have that page in my 2015 2500HD either Sent from my iPad using Tapatalk
  3. I have been using Amsoil in my 2015 since new and change it every 10,000 miles with absolutely no issues in 90,000 miles. Sent from my iPad using Tapatalk
  4. GMC-Joey I used painters tape to find my whistling. My dealer was great! When I told them I finally found it, they just replaced the light assembly and all was fixed.
  5. There are numerous threads about this. I do not know how to link them, do a search and you will see lots of possible useful remedies. Hope you get it fixed!
  6. I have averaged 19 MPG in mine. Here is a snapshot of the onstar page
  7. I like them, where did you get them and how was the install?
  8. Just wanted to let everyone know that my whistling noise is gone. I have driven it for a couple of weeks without any noise. Here is a breakdown of what all was done to my truck: Drivers mirror replaced, XM antenna replaced (TSB), VIN identification rivets (TSB), center light assembly replaced. The dealership was always concerned and helpful with trying to find the problem. I am glad it is finally gone and I have a quiet interior.
  9. The dealer replaced my center light today. When I looked at it, there was a seal between the light and my cab. When I asked, they told me it was an update. I do not care as long as that annoying whistle is gone. Hopefully after numerous trips to the dealers and numerous items being changed, I am fixed. Only time will tell.
  10. Well the tape trick seems to work. I seemed to have narrowed it down to the center light assembly. I will have the dealer order a new light assembly and that should fix my whistling problem.
  11. XM antenna did not fix the problem. On a recent trip, it was whistling a lot. Stopped at the first Lowe's, bought a roll of painters tape and followed odonnell747's idea and started taping things off till it stopped. Just like odonnell747, I believe it is my center light assembly. I need for it to warm up some so I can be sure this is it. Mine only seems to whistles when the temperature is above 60 degrees. Sorry it has been a while, but the temperature is a factor now.
