This is my first post and after seeing the duration and number of pages on this one thread, I'm not hopeful that my issue will ever be resolved.
I bought a 2016 GMC Denali 3500HD Crew DRW 4x4 on 3/31/16 (traded in a 2013 black 3500HD Denali Crew Dually 4x4 that never exhibited any vibration). I've had both steering wheel & wheel/tire vibration problems with this truck since I bought it new from Beck and Masten GMC in Houston, TX.
The first time it was brought in was on 4/19/16 with 579 miles. I've attempted to let the service department resolve this issue 6 separate times where they have used the Pico, and RFB'd the tires each time. No tires or parts have been replaced to date. The truck now has 17,999 miles and it still has the same issues - extreme vibration of entire vehicle at 60+mph and steering wheel vibration/wobble from 35+mph. The truck is back in the shop currently and the service manager left a voicemail on Friday that they had found one bent inside wheel in the rear. I'm frustrated beyond belief.
Without me having to read the 700+ pages in this post, can someone summarize what the causes/fixes have been?
Also, how I can contact the regional GM customer service manager or whoever I need to talk with?
