I know this doesn't help all of you here and elsewhere who's had this problem, but I joined just to say THANK YOU to all of you for posting this up on this forum. You have saved us a great deal of money and heartache. We'd been looking at a Tahoe LTZ for about a month, and spent the last week at no less than 5 dealers all over the state of CA looking for the right one. We thought we'd found it yesterday and went to buy it. The dealer made a great deal over the phone of $1,400 under invoice. Within minutes on the test drive we were like "what is that noise?". To us it sounded like a booming, buffeting or helicopter effect that you get with the windows down. Then my ears starting hurting. We got out and both of us had headaches. I think we drove it all of 15 minutes. We were very literally several minutes from purchasing and googled and found this forum. We read some of your posts while sitting in the Chevy dealership! Needless to say, we backed out and drove the 100 miles back home without a Tahoe. This was a 2015i...so obviously the problem hasn't been fixed. Too bad, because it's a great looking truck. I hope GM does the right thing by all of you. We've owned several Silverado 2500s and have always been happy with them. Really disappointing to see what GM is doing (and not doing!) with these new SUVs.
