    I assume Monk is over 100k miles and not many 2006's will be older than mine and mine turned 8-yrs old a couple weeks ago.
    But Monk should advise us ODO Miles and date of purchase date if he has not already.

    Here's something that may help...I put the display screen into diagnostic mode and took it for a drive. It drove normally for a little bit, then I felt a "jerk". The problem then started. The VSC and small orange "!" lights came on. The 12v voltage started to jump from 12.5-14.5v. What does that tell you?

    I would start by replacing the inverter. However it is also possible that the transaxle (which houses MG1) will also need to be replaced.

    Used inverters can be easily found on eBay or salvage yards, for example autobeyours.com

    They are fairly easy to install if you have reasonable DIY skills.

    If the transaxle needs to be replaced that will be much more difficult. Typically the engine and transaxle are removed as one unit after the suspension is taken out. Used transaxles are pretty inexpensive, the big charge will be for labor time.

    I doubt that Toyota would give the OP a break on repair pricing since he bought the car in its current failed condition.

    ...I forget if we already told you the first step is always to assume the 12v battery could be bad and causing the probs...need to check that first

    Another symptom...the car sometimes has trouble shifting from neutral to drive or reverse. Doesn't always do it.

    Get the code reads then report back here with the results. Your problem might be different. Upside, you are inBay Area and have two reputable independent mechanics (Art's Automotive and Luscious Garage).

    "Maintenance Required," light is just an oil change reminder light. Its triggered every 5,000 miles, and stays on until reset. Owners manual has the reset procedure. Since you might ask:
    • Get odometer to total mileage odometer, if it happens to be on Trip A or B odometer.
    • Turn car off.
    • Keep ODO Trip button DEPRESSED; don' let go.
    • Keep foot OFF brake.
    • Press Power button Twice.
    • Six dashes will appear, where odometer mileage numbers where, then goes to 5 dashes, 4 dashes, 3 dashes, 2 dashes, 1 dash, then six zeroes appear, finally mileage odometer reading again.
    • Maintenance Required light is now reset until 5,000 miles.
    • Release Trip ODO button. Turn car off or start car.

    Here's something else that occurs. The tail lights/ dash lights will flicker when the problem occurs.

    I disconnected the 12V battery to reset codes. Reconnected it and drove to autozone and the only code that showed was the inverter converter so I assume that must be the main problem. How hard is this to install? Any DIY's how to install one?

    Thank you exstudent. Just got this reset today. Realized my mileage wasn't reset the last time the oil was changed so this light came up and I came here to find a way of resetting it.
    Highly appreciate.
