2018 350 RXL

Over the last two months the car has an annoying squeak from the center arm console.
Of course the dealer couldn’t hear it or so they say.
It’s gotten worse.
Anyone else have this issue?

 

Sounds like the dealer took it for a ride themselves. You have to insist they accompany you for a ride so that you can duplicate the problem and clearly point it out to them as you both listen to the squeak.
You have to do this on any problem when you get the "3 monkey response". (see no evil, hear no etc).
