I have had no problems in 6 months and 9000 miles. There was a 'recall' on the hybrid system - they reflashed something on the computer. It may have improved economy by 1mpg, but I've only had a couple of normal tanks since then. (It has also been above 100 every day, so the AC is on constantly.)

I have not played around with N while driving. On a side note, the ICE always turns on when you go in reverse. I think this has to do with the gearing, so that you can back a trailer.

One big drawback compared to Prius is that there is no SOC display - so it is hard to tell a quantitative effect of regen or to take advantage of when you know you will have to run the ICE.

I just increased the tires to 40psi cold this week. The ride is rougher, but handling is still good. The ride was so smooth before, it actually feels like a truck now.
