After owning the car since day it rolled out at the shop, I have come to know this car fully in my last 9 years of ownership! I am surprised as to why ratings here are so high! Every TC owner I know has these issues. Moon-roof motor died within first year, they replaced it, then again the second, I had to pay for that, and then again the third year, by which time, I didn't want, a yearly, $1000 fee to use the Moon-roof 4 months out of the year. That is $250/month!
The gasket that seals the hatch/trunk door had melted by 3rd year and there is no ownership on dealership's part for this low quality rubber's use. After few winter/summer cycles, you will have this issue and your trunk becomes unusable regardless of the outside temperatures.
Trunk release switch cover is even worst, it literally melts into the plastic contrition that sets the release. It was very painful to get all the rubber out of the switch, now running without the cover, so the switch is operational, but, due to exposure to the elements, it died, and had to replace it, but second one melted too, so had to do the same. Removing that melted rubber is neither fun nor quick!
The engine, on average, burns 1 quart every 1300 miles! This can get real expensive, especially if you using good, fully synthetic oil. Apparently, this amount is well under their limits! There are no regulations or laws, so companies can set their own limits internally as to what constitutes "excessive"!
Be aware of the excessive oil consumption of this car. My 2007 Tc started burning oil at around 50,000 miles when the oil lamp turned on. Toyota extended the warranty but will not fix it for some reason. They will tell you to take oil consumption tests until the warranty runs out in 2016. Google this problem and you will know more. I will not recommend anyone buying any Scion car until Toyota commits to fixing this problem.
