Whats that squeaking noise coming from the dashboard?
It most likely is the dashboard. As your driving over bumps, press on it and see if the noise stops. If so, your best bet is take it to the dealer to be fixed. If you feel comfortable taking apart the dash yourself, you’ll see Dual-Lock (Velcro) fasteners/adhesive tape which attach to the dash. The adhesive on the fastener has probably come unstuck. Try pressing it back down or touching it up with some fresh adhesive/glue. Also be sure to check the parking brake release button. It could be rattling in the handle and the sound will bounce off the dash.
