There have been questions around exactly what parts were covered under the California emission warranty, especially the transaxle. I just downloaded the warranty booklet from the Toyota owner web site and looked in there. The language wasn't clear since it only shows the part list for WA and PA, the two states that have shorter warranty period: If we argue that the only difference between PA/WA and other states (with CA emission warranty) are the time/mileage interval, then the list of parts for other states should be the same, even though it is not explicitly printed out in the booklet. Now both "Motor" and "Generator" are listed - looks like transaxle to me. Also interesting to see that the inverter is listed.
