Hi All. Been a while since I checked in. Did anyone ever get any relief from the booming/pressure/buffeting by installing the Borla exhaust? Back in the day, probably 2 years ago now when this thread was on fire, adding/replacing exhaust was being experimented with before focusing on the tires. Just curious...

I call BS on the 2017's being improved. Drove a 2017 Denali with 22"'s and turned back in 15 minutes because of the headache the buffeting was causing. I then drove a 2017 Premier Tahoe with 20"'s and the buffeting was even worse in the low 40 mph range. Salesman asked me if the windows were down? Laughable. Having had 2 repurchased for this issue I know exactly what to look for. Buyer beware of the 2017's. Nothing is changed. I was optimistic about body mounts, exhaust changes, etc. All for naught. You may as well start a new thread called, "2017 xxx Noise in Cabin." I'm done with this body design.

Sorry to hear this news. Stinks. I know exactly the pain you have. It was unbearable! Headache walking into work, headache walking the in the door at home caused by the daily commute. GM repurchased both of my 2015's because of the exact issue you describe. I saw physicians and then went for a buyback. I recommend you do the same. There is plenty of precedent on this thread alone. Forget lemon law. Demand a buyback.

Leslie, your post and its specifics are exactly what we have been waiting for! Thank you for taking the time to post your solution step by step for us to take to the dealer. Thank you!

Thanks for the update, Jim. I asked a while ago if anyone found relief with the "exhaust fix" on this forum. Do you know what the updated exhaust consists of and do you know by any chance if the 2017's have the "updated" exhaust? I am sure others would be interested on with any details regarding this fix. I may try for a third time with a 2017, but need some confidence they have at least addressed the exhaust with the new ones. Thanks again for your post!

Hey All, its been a while. Hope you guys are getting some answers with appropriate resolution... Whatever happened to the "Exhaust Fix"? Did anyone find any resolution? Any chance they will have figured this out for the 2017s?

I tried the cotton ball thing back in the day...did not help with the buffeting and ear pressure. Cabin just made some really crazy sounds...

Get at least 250 miles on it before taking delivery. My second one was perfect until 200-250 miles or so. I thought it was great at first and then it came back worse than the first one. Get some miles on it. Focus on 35-45 mph.

I would agree 100%.

Great job!

Despite the fact I had both my 2015 Denali's repurchased, I can't stay away from this forum. I am truly rooting for you all to find a solution. If you're new to this forum and are experiencing problems, be sure to open a case number with GM immediately. It is the first step to a buyback. Good luck and can't wait to see the article!

Rooting for you guys! It amazes me that a handful of dudes on a forum who never met are going to get this fixed before GM...

Hat tip to Boaz: Everyone one this thread should follow this link. https://www-odi.nhtsa.dot.gov/VehicleComplaint/

Hopefully, this is the type of publicity will force them to do something about these issues. All 3 2015 vehicle platforms made the list. This vehicle needs a redesign. I just hope the taxpayers won't have to pay the bill.

What happened to Eddie from GM who was trolling this site? Coward. Help this man ^^^
