One problem related to dashboard crack has been reported for the 2009 Mazda RX8. The most recently reported issues are listed below.
I purchased a Mazda Rx8 new in 2009. I have noticed the passenger dash cracking. At first it was small lines, and I thought it was the normal look of it, but over time the cracks got bigger. I went to my Mazda dealer and they told me that other customers had same issues and they are still waiting for a Mazda recall. I have even seen other similar complaints online. The cracks look horrible.
