How old is the 12V battery? Check to make sure it is OK. Does the red light on the fob blink when you press the buttons? Sometimes the buttons get...
Don't worry about paralleling the batteries with different voltages. There might be a small spark initially, but the current will not be a concern...
Please ask the Tech what the "inf code" is for C1256. This is an additional freeze frame that gives more insight into the problem. The C1256 means...
Please call back and get the list of codes that were read by the Toyota dealer, and post them here. More opinions are needed before you pop that...
Those codes are for failing HV battery. Blocks 4, 11,12 are weak. All consistent with your symptoms, and not surprising given the mileage. Your...
OK, didn't know about the recall on the switches. I would say that PriusChat statistics are a bit skewed, in that those with problems are much...
Note that the brakes in the Prii are still mostly functional even without that switch working, so it may not be all that unsafe. The stroke sensor...
Was the car in Ready mode in both cases? Not a 12V problem?
Rodent damage again! Another Prius Chat meme. Kudos to the dealership for actually repairing the wires. In past cases where this happened, the...

That light is showing that the hybrid immobilizer is functioning. As said, it is always there in a properly functioning car turned off.
At the least, get the codes read and list them here for second opinions. There may be some alternatives, such as used parts, that can reduce your...
I think the trouble would possibly be the steering motor, rather than the steering ECU (controller), since no error lights are mentioned. If the...
How were the buttons on the old fob? There are some reports of the buttons getting stuck in the depressed position, and that will render the fob...
Answered in your other post. No need to double post. Things generally get answered around here.
Without the mini VCI to do this sort of thing, you need to clear the DTC's with another chicken dance: 1. Short pins 4 and 13 of the OBDII port...
That is a classic indicator of the 12V battery being low. This is seen all the time here.
To remove it, pull off that snap-on plastic bit that covers the nut at the bottom end of the arm.
I have seen reports of rough idle and shut down due to fuel system issues (injectors or MAF dirty) but without any DTC to report it would be just...
