same thing happened to me. I received the first letter, stuck it in the glovebox, never got the second letter. inquired with a dealer on what to do, they acted confused and wouldn't do anything so I waited for the second letter. When it never came I sent an email to Toyota USA on May 22. They waited until June 1 to respond, asked me for my vin and mileage, then asked me to call, then told me that I missed the cut off date of May 31 and was out of luck. On the phone with them now, and a lawyer next if they can't figure it out.
