Takata inflators. I have a loud cracking noise in several places behind the dash. Sometimes it happens when the car is still but mostly while driving on interstates. The loudest cracking noise is in the center of the dash. With the takata airbag recall I am afraid that this could be part of that. The car only has 11,000miles on it but the cracking has occurred since the car was new.
