Need advice on buffering issues 2016 Yukon Denali

I have a 2016 Yukon Denali with almost 20,000 miles on it and I have hired a lawyer to deal with my Lemon law case. I've never noticed the buffering issue till lately when I've had some problems with my ears and now I can't even drive the car without pressure in my ears. Then my husband had some dental work done and we climbed in elevation and the pain in his jaw and ears were unbearable. Should I take it in? Could the buffering just be starting now? Any advice would be great.

Did you buy it new? What's the built month? Wow so you never noticed before?

Most of the issues are present when new but there's reports of "perfect" trucks at delivery getting the booming/buffeting after time passes

I think I would do what my Lemon Law attorney recommends.

I bought it brand new, it had 150 miles on it. I've never noticed it before but we never have really climbed any elevation which is when I husband noticed it. Then I just started having some ear issues but they will be completely fine at home and then as soon as I drive anywhere even a few miles, I can't get my ears to clear or pop for hours. It's really weird. I will check my build month but I've had it for 13 months now.

New Michelin Premier LTX have helped a lot of people

Get them road force balanced at an independent shop aiming for values under 15

^^^Ditto. I'm guessing the tires with miles have become worn and out of balance where it creates unnecessary chatter to chassis which creates the well known buffeting (cabin pressure.) It shouldn't be an issue and wouldn't be with most vehicles, but that's not the case with these trucks. We had horrible buffeting with our 15 XL and since replacing tires with Michelin Premier LTX and ensuring they were road forced balanced (under 15lbs) it eliminated 90% of the problem. I sold the orig oem wheels and tires to a buddy that installed on his older GM truck and they've been just fine for him with zero issues.

That sounds logical. This chassis is susceptible to transmitting these vibrations throughout the body.

What fixed mine was: Roof Crossmembers re-secured, change to Michelin Defender LTX M/S2 tires, new drive shaft, replacement of the front and rear ring and pinion gears. The issue was lessened after each fix, and went away all together with the ring and pinion replacements. Mine started with 6,000 miles on it, I now have 53,000 miles on my Yukon with no more issues. It's been the best vehicle I've ever owned once the issues were resolved. Give your dealer a chance to fix it. The big fix was the Ring and Pinion replacements, both front and rear! I have the tires Road Force balanced every 6 months and check the alignment at the same time.

Make sure they Road force balance your tires and get a number of 15lbs or less!
