So, I am having similar issues with my own ride (with regard to the pressure buffeting). Tell me if this sounds familiar: Buffeting felt in ears as much as heard Headache inducing in some cases Triggered by any kind of bumps in road (big or small) Washboard surfaces are the worst Large wheels and low profile tires (21" rims) Tried road force balancing - no help Tried switching to smaller rims (19") and tires - no help Tried sound deadener - no help Now for the kicker...I don't own an SUV. I am talking about my Tesla Model S. In all my online research, I came across this forum and this issue (you guys have the unfortunate honor of being the worst victims), as well as a few others including: Last generarion BMW 3 series hardtop convertible Porsche Cayman Skoda (Octavia I believe) Anyway, I am posting here just as an FYi. In my case, after my HOURS of diagnosis, I kept coming back to the giant hatch. I simply felt it was "moving" ever so slightly whenever hitting a bump and thus generating a pressure wave. The general assessment on the Tesla forums was you needed to adjust the four rubber hatch adjusters. I did this endlessly, but ultimately decided the rubber was too soft - particlarly for the center adjusters. I decided to unscrew them entirely, cut a couple of pieces of heater hose and put them in place. Stil rubber, but much firmer. The result was a 65-70% reduction in the buffeting. I am still working this angle, but I am definitely on the right track here. Now I post all this simply as another point of reference for all you folks and to say that perhaps the whole roof thing really is on the right track and the owner who jammed in some shims (under the headliner bows I believe) was probably right. Sure, it shouldn't flex, but short of glueing some other big piece of reinforcing metal under the roof (which I would also consider), the options seem limited. Heck, if you aren't mechanically inclined (I am lucky in that regard) you might even consider having an auto upholstery shop pull down the headliner and have you come take a look and brainstorm some shim ideas. Yes, you should not have to do this (any more than I had to do this), but it may be the lesser of two evils here. Anyway, as this thread helped me think up some ideas, I wanted to at least pass this on!
