2008 Chevy Impala V8 Front Wheel Drive Automatic 3500km miles
I have a 2008 Impala SS with 8 speaker bose audio system. I have a bad vibration coming from the headliner when the radio is on. I have had it into the dealer 3 times in the last 2 weeks and they insist it is fixed, when it is not. They lubed the sunroof trim and other areas and the vibration seemed to lessen, however just above the dome light it where it keeps occurring. When I push up on the headliner it stops. Any ideas? Should I take the headliner out myself?
