So far we have 1700 mi., so we really haven't had any issues with quality and are pleased with fuel mi.( 34-39mpg). Come to think of it the AC seems to emit a musty smell when on fresh intake, switching to recirc., lessens it and I have tried both ECO and standard settings, w/ same results. I was wondering if the current TCH's are being built in the USA, as advertised, or are being built in Japan, I heard the first TCH's were built in Japan, and if this could be related to quality issues.
