    I took my car in for inverter service, 199,500 miles on the car. It drove off the lot correctly. Two days later the master warning light, brake system warning light, vsc light, engine check light and on the display area, it showed a car with an exclamation mark on it.

    Driving it back to the dealer when the car stalls. Toe it into the dealer and they said that the inverter system died. Ill get the exact codes, but it had something to do with a DC converter error or something. It seems suspect that the system "died" shortly after service. Could a dealer not performing the inverter service correctly cause this type of a system failure? They want $5,600 to replace the inverter system.

    Thanks everyone!

    What service did you do? What year is the car? At nearly 200k miles, anything can break at any time.

    It was the inverter service which is a fluid replacement. It is a 2007.

    can't think what they could have done that wouldn't have set codes as soon as you drove away.

    unless they didn't push a connector all the way in and it pulled out from vibration. or maybe the fluid slowly dripped out.

    Similar thing happened to me, after they changed the pump, per the recall. However, mine didn't overheat till about a week later, going uphill, on a very hot day. I managed to limp home, then found out they had not attached the connector to the new pump.

    Yes, it certainly could. There have been a few cases reported here of coolant not filled correctly (trapped air) causing it to later overheat. It's very important to check for correct coolant circulation after changing it out.

    Like Rocketman said, inverter cooling problems don't always show up straight away, particularly if you're mainly doing short trips or taking it easy. The problems often don't show up until it's a hot day or your drive is a bit harder or longer.

    No dripping that I could see. Thanks for checking. I feel better having the comm

    I guess the problem is that I cant prove that the dealership did anything wrong. I mean how could I? Man this sucks.

    Luckily, used inverters are cheap on Ebay.

    I would complain to Toyota service manager about the failure right after service. Give them something to think about.
