2012 Subaru Impreza: The Dash Rattle
October 22, 2012
Santa Monica to Famoso and back is about a 300 mile round trip on interstate 5 and California route 99. For the trip I chose our long-term 2012 Subaru Impreza, which was economical, comfortable for myself and my three passengers and fun to drive (I used its paddle shifters often).
But there was one problem, however. A rattle coming from underneath the right speaker grille in the Subaru's dashboard at the base of the A-pillar.
Mark Takahashi mentioned a similar issue a couple of weeks ago, but the rattle I've experienced in the Impreza is not heard during city driving, even over rough pavement. Instead it's a highway speed issue only. And it's loudest at 75 mph when something loose in the dash seems to be at odds with the frequency of the harmonics created by the interactivity of the road and the Subaru's chassis and structure.
The good news is that if my passenger would reach up and push down on the speaker grille the noise would stop. Hopefully that means it shouldn't be too hard to diagnose and fix.
We'll have it chased when we take the car in for a scheduled maintenance later this week.
