Has Toyota ever owned up to the cracking dashboard issue? I heard a rumor that they were covering dash replacements for 98-2008 Toyotas, but I was never notified of this extended warranty. The person that told me about the warranty said that it has since expired.
You can call any Toyota dealer and ask about any extended warranties on the dash pad. Far better source than a friend, acquaintance or faceless entities on the internet.
Your car is 15 years old now so don’t get your expectations up.
