Well, guys, I need your always sage advice. I went to my local Toyota dealer last week for my usual 5K service. This is my usual service place as Lexus is far away. While there, after reading about inverter troubles, I asked the service manager if he had ever replaced one or a battery. He said he has never seen an inverter go bad and only one battery. He said that was in a ’01 Prius with over 300K miles that was used as a taxi. This, of course made me feel a little better since I’m now at 106K. But (always one of those) he said I was due to have my coolant changed in both the engine and inverter. He said this would cost about $300.
My questions are:
Does the coolant really ever wear out? Mine is clean and bright, never leaks.
Is $300 reasonable?
Is this a DIY project?
What do you think?
