I found this post on another forum and thought it was worth placing it here FYI --- In [email protected], "jjacob_uop" <jesse.jacob@...> wrote: > > 3,000 miles outside of the extended warranty and the master warning > light came on last Friday, along with the text "PS MAIN" on screen. > Had it towed to the dealer and they say the inverter is bad. In case anyone is interested: dealer replaced inverter at Toyota's expense (~$4500 to them) last week. Dealer test drive revealed exact same warning/DTC situation followed by shutdown. Dealer now identifies transaxle as problem. Toyota is replacing at their expense (~$5000 to them), but we have to pay for labor (~$1500). Dealer continues to provide gratis rental, and will need the Prius for at least 5 more days. They're leaving the new inverter in the vehicle even though it's not the problem. They offered no sensible explanation for this--but it's their money so I'm not complaining. I'm very happy with Toyota's help so far. As much as I love this car, there is no way I could justify $12k out of my own pocket (parts + labor + rental). I offer a very sincere wish of luck to the rest of you with hybrid parts over 100k miles! Here's hoping I can get another 100k out of mine before any more problems...
