My 2003 Toyota Corolla which was bought brand new in may of 2002 has had several dashboard and radio issues. Two months after purchase the whole dashboard needed to be replaced. Afterwhich my radio no longer was flush with dash, the dealer attempted to fix several times to no avail contacted Toyota directly, they sent a manfacturing rep whom fixed the radio however created a bigger gap b/w radio and rest of console. Toyota is considering this a manufacturing design not a defect. Was told would "rob peter to pay paul" in order to fix. Now dash is falling apart again as well as the rest of the front console. Looks as though was glued together.
