If neither of those two things fixed it, it's probably the motor/generator itself having an intermittent open circuit in one of the windings. New motor (MG-1) time, I'm afraid.

SOURCE: Toyota Prius jumps from Drive to Neutral while

We had the same issue in our 2008 prius happen last week. Car slipped out of drive after initial 1-second acceleration three times in a row. Powered the car off and on in between incidents. Toyota shop has not been able to re-create after 100 miles of driving over the last few days. They replaced the shift lever and battery (the potential culprits based on scant research), but no one seems 100% confident about it. According to the Toyota shop, the advice given by oneStan above isn't applicable because "the Prius actually has a transaxle that does not have cables or linkage, it has an electronic shifter. Mounts such as engine or transmission very seldom wear out before 150k miles." We are supposed to pick car up tomorrow but feeling anxious about driving our toddlers around in it after what happened. Would very much appreciate any advice. Thank you.

SOURCE: wheres is the ecu located

It's behind the right side of the dash. Pretty much dead behind the air conditioner vent. Should be accessible once you remove the glove box.

This code comes on my 2002 chrysler and I need to know what cencor I need for my car trammission slips y rpm goes up and it is code p0700 and code p0a41

the po700 code means the transmission control module is getting an error, and the p0a41 is just related to the low circuit error caused probably by the p0700. You transaxle module could be in error, or you have a trans drive motor giving an error? i had to change my Transaxle module, or computer, when my 97 Cirrus started not shifting right. You need to have your mechanic or transmission shop diagnose it to be sure.

The Triangle indication:
Description: MASTER WARNING LIGHT.
The battery ECU has a self-diagnosis system. If the computer, High Voltage (HV) battery system or the components are not working properly, the ECU carries out a diagnosis to detect the malfunction, and illuminates the master warning light in the combination meter together with the HV system warning indicator on the multi information display.
NOTE:
The master warning light illuminates when the HV battery system fails and it blinks when in inspection mode.

Nine error codes - car lost power and stalled

Yes it may take several hours to evaluate the problem with so much of codes.
But at last it may be a simple fix.
Ask him for an estimate to check the problem.If its too costly just trade in your car.
I dont hink it will be too costly to just evaluate the problem.

Prius has a dead utility battery

Unfortunatly, the Aux Battery on Prius is susecptible to premature replacements. All the Aux battery does is "power-up" the various ECU's which in turn allows the HV battery to start the car. The AUX battery does NOT operate the starter.
