The rattle we had was coming from headliner behind the passenger seat, and was typically worse at medium to highway speeds. It is noticeably louder with the sunroof cover slid back(open). My fix: Open rear passenger door and stand on running board to access the roof rack. If you wiggle the crossbar of the rack it has the slightest of slack, but just enough to make a clanking sound. I wedged some thin flexible magnet pieces(no the rack isn't magnetic, just what I had handy) in between the crossbar and the roof brace in front of and back of the bar(see pic). Viola...no noise. If these come loose I will come up with something more robust(maybe some two part epoxy). I'm not familiar with the inside of the 2015-2019 Suburban, Tahoe, and regular Yukon's, but the ultra quiet cabin of the Denali amplifies ANY little rattle or strange noise. I was used to the road noise and rattles of my 2007 Suburban(288K). They went kind of hand in hand. This one will take some getting used to. I know, suck it up buttercup. Now...back to the "other" issue... front end clank, clank, clank-clank after medium to hard braking, but occasionally during acceleration, and less occasionally steady speeds. No specific rhythm, almost like it's swinging in the wind, and then it suddenly stops after a few seconds. Please help if you know anything! I WILL fix this too! There is a video from another in a different thread on here that has the EXACT same issue/sound as mine.
2016 Tahoe rough idle I have a 2016 Tahoe Z71 that has been to the dealership 3 times for a rough idle. The motor mounts have been replaced as per the bulletin from GM but the vehicle still idles rough at stops and sometimes in Park. I contacted GM customer service the last time I took it in and got an email stating that they were concerned that I was having issues and customer satisfaction was their goal in this issue. So I tried emailing and calling the number I was given and left several different messages but got no response. After about 2 weeks a senior customer service representative contacted me by phone. He stated he had researched my vehicle’s history and saw that the motor mounts had been replaced and at this time there was nothing else that could be done. He said that the rough idle was a “characteristic of the vehicle”, it does not effect the performance or integrity of the motor. He then went on to say that there is a bulletin out for this issue and further investigation is being done to fix this issue and when there is one they will fix my truck. Wow! If it is a characteristic of the vehicle why is it being further investigated to be fixed? I drive a 2012 Tahoe for work everyday and it idles in Park for at least 9 hours a day and still that work truck does not idle rough like my personal vehicle. It’s sad to see the quality of vehicles GM is putting out to their customers. You hear buy American but it’s hard to when u have issues like this. So much for GM’s customer satisfaction when they tell u there is nothing else that can be done for the $60K vehicle you bought from us that does not run the way it is suppose to. I’m sure there is a lot of you out there with this same issue. Wondering if anybody has gotten any kind of fix for this? Thank you RDOrtiz11
