I have a 2015 Volt with approximately 35,700 miles on it. I bought it new from a dealership in Torrance Ca. The car has been pretty good except for the constant dashboard rattles. Has anyone experienced a passenger side dashboard clunk when hitting sharp bumps? The clunk is coming right from under the passenger side dashboard hump. Maybe the passenger air bag module is loose? It sounds like metal on metal clunking. It started about 6 months after I bought the car. So tired of this particular dashboard clunk. Everytime I go over a rough patch of road, the dashboard clanks away. Makes the car sound like a bucket of loose nuts and bolts. Quite the advertisement for Chevrolet quality when I carry passengers. The dealership that I bought the car from has been of zero help. They hear it but keep giving me excuses for not fixing it. Any suggestions? Are there any TSB's I can tell the dealer about? Thanks
