I was extremely pleased the first 12 months. However, for the past 4 months, a a sharp clicking rattle-like noise started to occur and became increasingly persistent as time went by. It took literally 8 visits to the dealer before the problem - faulty sunroof construction - was detected by me from researching tC noise rattles on the web. Upon hearing that there was a Toyota Service Bulletin (TSB) on the earlier models at a tC Owners Blog, I showed the article to the dealer. He then advised that there was a second TSB that I qualified for, and after I left the car with the dealer for 2.5 days, I got a completely new sunroof - all new glass and rails. Now, I'm in "heaven" again.
Steering wheel-mounted stereo controls, rapid acceleration from start.
More headroom. I'm six foot and sometimes I have to tilt back or literally push up on the sunroof cover to get it off my head.
