The Suburban is great the 2026 is good except for the wind noise and rattles I had a 2024 RST 3.0 no rattles or wind noise the 2015 Suburban was also great. Just tired of trying to get this problem fixed. MY 2016 Silverado was great the 2008 Suburban was great the 2004 GM SLT was great.
I have the same issue with 2026 Silverado LTZ also rattle above 60 dealer heard the noise offered no help said they could not find anything master tech road with me and heard the noise and rattle no fix contacted GM started a case now getting no response
I have the same wind noise problem on the interstate or anytime you hit 60 mph or higher brand new 2026 LTZ wish I had kept my 2024 RST I was thinking of looking at the 2027 when they come out not sure if I will.
When the truck gets to about 60 mph and faster get a rattle by the front windshield and a pillar area on both sides I have a 2026 Silverado LTZ any ideas on where it could be from
techlink has all the online classes that show how the techs are supposed to diagnose the problem with vibration the march 10th 2015 issue deals with part two the driveline etc they are aware of the problem. IN the end if the tech can not resolve the problem with spacers they say just replace ring and pinion gear. That is after they have elminated the tire as the cause. I couldnt get the page to copy.
Just google gm techlink then go to archives and click march 2015 scroll down to vibration analysis this may have already been posted
