Highway speed vibration on 2020?

Recommended Posts

Do you have a high optioned trim?  SLT or higher on GMC, LTZ or higher on Chevy?  

 

If so, there is a service bulletin coming directing dealers how to fix.  Should be available next week.

Steering calibration is now available at dealers to repair the majority of these issues.  The service bulletin is not up yet so all dealers may not be aware.

Mine is an '18 that has had Michelin on it since new.

 

Always smooth. 

 

It's on 18's rather than 20's.

I am having the same problem. Steering wheel shakes at higher speeds. Had tires balanced and then two tires replaced and still has issue. Mine also has loose steering that comes and goes.
