I got my Prius cooling coil replaced and on the way back home I tested the car by pushing it down and next few minutes...I wan standing on the road looking at the most illuminated panel of my car...the mechanics failed to check the coolant level and the car had gone hot...the system shut down the ac system and with temperatures ranging in 40 Celsius it was difficult to sit in the car especially with its blower was throwing hot air...got the car checked through Toyota and they say it's related to inverter cooling system which might have gone faulty.....anyways the car will be sent to workshop on Monday next and than we will see what does it cost to have it repaired / replaced....needless to mention that Toyota does not cover such reported and established errors in Pakistan.

Same as described. Dealer had car for 2 weeks. "Cooling pump inverter on back-order"
Am picking up today and will se what they charge, if anything.
I think this should be covered under drive-train and/or hybrid battery warranty.

I had the same problem and I called Toyota they also said my car is not part of the recall. Yet the problem I had is exactly the same as they described for the recall.
