How many of you DO NOT experience buffetting and vibration problem?

LI Tahoe · Feb 22, 2018

check out my thread in the Engine and Drivetrain section.

New torque converter and transmission parts have definitely made a difference, not 100% but at least a lot more tolerable.

HUGE shout out and thanks to member "BADRIDES" Jason, who suggested the torque converter replacement was an option to look into. Its not mentioned in the TSB for buffering. BEST OF ALL its 100% covered by the 100K transmission warranty

Powertrain warranty was chopped to 5/60k for 2016+ which sucks

I don't think I have heard of any 2018's with buffeting, booming, or vibrations. Am I right?

I haven’t heard of any complaints thus far. Hopefully they worked some magic and it’s GONE!

I don't want this thread to become a heated topic. I believe their claims are very real and valid. However, if you experience none of the buffetting or vibrating issue at certain speed (not due to unbalanced tire) please let viewers know. I honestly want to get a feel of whether this just for a small groups of vehicles.

Buffetting issue is like when you are driving with one window down and it builds up a high pressure in the cabin and makes your ears uncomfortable. They are experiencing this problem even when all windows are up.

My 2016 Tahoe bought used and my 2011 Silverado bought new do what u describe when both front windows are up and a rear one is open. I simply crack open a front window and the buffeting disappears. Never been an "issue" with me.

That’s not the issue they are referring to.

Buffetting occurs with the windows up and booming feels like you are inside a giant drum. Generally at speeds under 50.

Vibration occurs, generally, over 75mph and is exacerbated on long sweeping turns.

There are TSBs for both.
