2007 Prius -- just bought it -- having some problems :(

Hi everybody. I am the proud new owner of a 2007 Prius with 57K miles with a new hybrid battery and 12V battery, and I'm having some problems.

HISTORY

When I bought it about a week ago, there were no dash lights on (except the tire pressure light, which is still on and I tried to reset but didn't, so needs to be looked at) and everything was working great.

About a week and 500 miles later, all of a sudden many lights on the dash came on -- the red triangle with the exclamation mark, VSC, check engine, a car with an exclamation mark, and a car with an exclamation mark on the top left corner of the MDF, etc -- and the A/C stopped blowing cool air (still blew, just not cold).

My wife took the car to Pep Boys (I was away on a trip) and they changed out the fluids and reported the following engine codes: C1241, P0A93, and C1300. But then, the lights all went out again right after the fluid change, so my wife continued using the car.

Now, I'm back in town and all of a sudden, the lights have come back on, and I'm investigating to see what's going on and would appreciate any insight before I take it in to the dealer for repairs.

MORE HISTORY

Based on the P0A93 code and some more digging (no waves in the reservoir), I think there's a problem with the inverter cooling pump and that it needs to be changed (it's still the original unit with the black base). I would appreciate any insight here: do you think this is worth doing at the dealer vs. any mechanic (it seems like a simple swap)? Should I do this first, before I take it to the dealer?

I checked the batteries (hybrid and 12V) and all is well there: voltages, connections, everything is fine. This is to be expected since they are both less than 6 months old.

Thankfully, the inverter also appears to still be working fine.

My main concern is that use of the car with a faulty inverter cooling pump may have damaged some electronics aside from the inverter (could this be the cause of the C1241 and C1300 error codes?).

When the lights all came on this last time, the A/C and cruise control suddenly stopped working and also like a black bar, dead zone, appeared across the top of the MFD, below the car with the exclamation mark (see picture). This dead zone/black bar disappears when you enter diagnostics mode and curiously is exactly the same height as the PROBLEM indicator that appears on the MFD when I first start the car. I entered diagnostics mode and the following codes appeared: 01-DC-190-30-2, 01-D5-190-67-F, 01-DB-190-98-F, 01-DB-110-E5-2 (see picture). What could be going on here?

I would greatly appreciate any insight you all may have before I take it in to the dealer.
Lastly, should I have it towed to the dealer or can I drive it there (15 minute drive)?

Thank you all very much in advance.

 

Thank you all for the replies. So I went ahead and ordered an OEM (the updated version) inverter cooling pump and Toyota coolant online (total cost like 120$ on Amazon). Then, I found a local auto shop about 5 blocks away that did the installation for 1.5 hrs of labor (total w tax was 163$). All of the lights disappeared, the MFD went back to normal, and the car runs great now -- everything works, AC included. Mechanic scanned the engine codes again and gave the car a clean bill of health. Thanks again!
