Gee, my permanent one was issued 10 years ago, in 2008. I just today got a notice from DMV that it was time to renew. “Please turn to back of this form and check ‘yes, I do want 2 new placards issued’ Or “I don’t need handicapped placards issued’, sign and date, and return in the postage paid envelope. Your placards will be mailed to you within the next 30 days.” Mine don’t expire until December 2018. I’ve already done it. So different from what you’re going through.
