I have an early FJ got it in April 06. What can I say I was an early adopter, last four on the VIN 4844. I haven’t had any major issues, I had the tire recall so I got a new set at 5000 miles and I had the rattle in the roof rack the dealer fixed as soon as I reported it. I just got a crack in the windshield end of Dec 07, I don’t conceder any of this a big deal. My rig is almost 2 years old now with over 32K and all in all I’m quite pleased with it. 
Just for reference, I drove a Chevy Astro van for work a few years ago that needed 3 windshields in less than a year, two in 30 days! They just kept cracking. And you almost needed to change a headlight every oil change. Never saw a recall for any of that.
If you bought you FJ to Mall Crawl, you may never see any issue other than door dings, but if you bought it to “Boldly Go”… You will probable have occasional issues, as you would with any vehicle used for rough service. If you off road sooner or later the carnage gods strike and if you can’t afford the down time on your rig, better to stay in the parking lot.
