Toyota Help
I've been discussing the situation with the Service guys at my local dealer for 6 months and they've been "watching for TSBs" with no luck. So, I called Toyota ~ 2 weeks ago just before I rolled over 36k miles so that they'd have my complaint on record in their system before my standard warranty expired (did actually purchase the 100k warranty since I drive A LOT for work and new I'd hit 36k pretty quick... which I did...but I figured calling them pre-36k wouldn't hurt). Anyway, the service agent told me that Toyota Corporate had very little mention of this issue that he could find while I was on hold and that anyone that has the problem should call them to report the issue since the local dealers may or may not report the problem back to the corporate level.
Calling Toyota is the only way to provide direct feedback/complaint as well as ensure that they have record that your T4R had the issue before you hit 36k. If/when a fix is issued, they should contact you directly if you're in the system with the problem.
So, call them NOW if it's during the day, tomorrow if you're checking the forum before bed.
