A/C started blowing hot air then Triangle of Death appeared approx 1-2 hrs later. Dealer said A/C repair was likely due to evaporator core leak that needed to be replaced. However, dealer estimated A/C repair to be $2700 which was more than half of what we paid for 13 yr old vehicle! We declined dealer repair & recharged A/C for $50 - we believe dealer was completely dishonest because they said they had recharged A/C when they replaced inverter water pump but we found A/C caps laying under the hood. Later found on Prius Chat blogs the A/C diagnostic code lights have been known to trigger when inverter pump goes out.
