Wanted to know if anyone can chime in on this.

So the dealer had just adjusted the parking brake lining on my 2014 GS non f sport because it was making metal clanking noise.

Now the noise is gone but i am facing a much bigger issue. Not sure if it relates to the adjustment they had done, but the car now vibrates randomly at any speed. The condition of the road i'm driving has nothing to do with this.

Took it to a dealer trying to hopefully duplicate the issue with no luck. They inspected the car for about 20 minutes (not sure what they did) and obviously found no issue.

anyone?
