2004 Prius Warning LIght and Engine lights

Did you ever change the transaxle fluid?

 

Give me a call and I'll discuss the options with you.

 

I wonder who provided training to the individual that you spoke with. That doesn't sound like a conversation that would promote confidence in that dealer service dept's technical capabilities...

 

She doesn't understand that without the codes we cannot help her. She needs to demand that the dealer give her a listing of the ODB2 codes that the dealer read out during their diagnostic efforts and relay them to us!

That dealer sounds pretty bad! They gave you the run around to get your money, especially replacing your brand new optimo battery. What nonsense saying that it's "not compatible". Wonderful how they only fixed the real (warranty covered) problem after they'd extracted this money from you. Now I don't know if some of those things were necessary or not, but based on what they said/did with regard to the battery you'd have to wonder.

 

Its rare to hear of just an Inverter failure. I would suspect a poor Inverter Coolant pump not working or pumping 100% or a poorly maintained Inverter coolant system. Old bad fluid.

I would address a Inverter Coolant flush asap. Its very cheap and protects the trans axle which you are rightly afraid of and the Inverter itself.

The Inverter Coolant system cools both the transaxle and the Inverter.

I would get the trans fluid changed asap also. I don't think you ever mentioned the miles on the car?

The car may have sat a long time before you bought it. Were there special circumstances to the purchase?

 

Never trust a dealer, especially if they think you don't know much about the car. A simple OBD2 scan which can be done by almost any mechanic, or even a parts store, and would reveal the true nature of the problem. If the Check Engine light came on, there should be an OBD code.

 

Its an easy thing if you have alot of tools. Jacks, jack stands,mats,hand tools,etc.
Don't know you so not sure.

Tell us a little about yourself.

 

I would call them and request to get those codes. Or go someplace else to get the codes scanned. Once, we have those codes, post them here and someone will be able to help you. You can get your own OBD2 scanner on ebay cheap, and do it yourself.

 

Generic code reader will usually not read Hybrid Codes. Requires Toyota Techstream software or a professional code reader.

 

Sounds like it's time to become a Better world club member. Maybe the membership with 100 mile coverage?

 

Unfortunately, AAA will make you wait a whole year before giving you 100 mile coverage. I think Better world club only makes you wait a week.

 

Based on your mileage (113583), if your car was originally sold in California and does not have a salvage title, the hybrid battery should be under warranty. If it wasn't originally sold in California, it may be under warranty if it was originally sold in a few other states.
