Prius (2010-12) :: Whining Noise Near Inverter When Charging 12 Volt Battery?
My 12 volt battery is flat. I attached my CTEK MXS 5.0 and started on the Normal setting. I figured (wrongly it seems) that having the battery charger attached would support in starting the car. The green light displayed when I depressed the brake pedal and I pressed the Start button, but everything went dim and the brake pump slowly wound into life. The Start button glowed was on but no other functions started.
I pressed Start again and the light went out. Now when I connect the battery charger, a whining noise starts from near the inverter. The speed varies; dropping from a peak and rising again, and there's probably a pattern to it.
I've disconnected the charger a few times and the noise stops immediately. I wonder if the car has not switched itself off. I've disconnected the charger and I'm waiting some period of time before connecting it again to see if something will fall asleep. If not, I'll just have to climb over the back and disconnect the battery from the car before I charge it.
Prius (Gen 1) :: 2001 - Inverter Coolant Leak?
My 2001 Prius with 134k miles has been running great but leaves a small amount of coolant on the ground after parking. I've had to add approximately 8 ounces per 100 miles.

I just noticed my 2010 Prius doesn't have the plastic piece/cover that goes across the inverter. I posted a picture of the black plastic/metal? piece/cover. Would any service require the removal of that piece? Only thing I can think of is the Dealer replacing the recalled brake pump assembly.
View 5 RepliesPrius (Gen 3) :: Inverter Coolant Reservoir On Low Mark
I have had my certified 2010 Prius since June 2015. Last Saturday I noticed my inverter coolant reservoir was on the low mark. I went to the closest dealer and they topped it off up almost to the full mark for free. I thought it had probably went down from evaporation and I just hadn't noticed it before. Yesterday I went back to the dealer where I purchased it which is about 90 miles away to have the CVT fluid changed. This morning the coolant was back down to almost the low mark. I looked on the ground and can't see any evidence of a leak. Tomorrow I have a appointment to have them check it. Since it is still in the one year certified warranty I don't know how motivated they will be to find the problem when they can't charge me for it. I don't think the level would have went back down right away if there wasn't a leak somewhere. I checked and there have been no recalls done or called for on it.
View 12 RepliesGen 2 Prius :: Inverter Coolant Pump Failures
Having seen the rather catastrophic outcomes that are possible with inverter coolant pump failure, I've thought a bit about adding a flow sensor in the coolant path. I even went so far as to buy a flow sensor, which would probably do the job. However, it's somewhat heavy, and then there's the plumbing job to take care of. Seemed somewhat challenging to pull off.
Since this aborted endeavor, I began thinking about ways to detect surface turbulence at the top of the coolant tank, and am now thinking that might be easier to pull off, even if it requires programming a PIC to do the monitoring. My current thought is to install an LED and optical sensor in the cap, and measure light intensity received.
Prius (2004-09) :: Seems Like Inverter Coolant Leaking
So, the sideways coolant tank in the engine compartment, not the one next to the grill, but the one that is sort of between the air filter box and that shiny metal square
I have always thought that tank was slightly low, but it has a seam just about where the full line is, so I was never sure....finally about three weeks ago, I worked up my courage and put a few ounces of coolant in that tank. THEN it was up to the full line.
So, a few weeks after adding the coolant, I had the water pump recall done. Now the coolant level is back down to where it was before I added....so I am assuming that the correct level is just below that seam that seals the top of the plastic tank to the bottom part of the tank.
Prius (2001-03) :: Code P3125 - Bad Inverter
I bought an 01 Prius with 148k miles. It had code P3125 which mean bad inverter. I replaced the inverter with one from a junk yard with 81k miles. As soon as I was done the car started right up, and I didnt get electrocuted!
Right after the car started I got codes P3115 P3001 and P 3191. I cleared them out and turned off the car for a min.
When I started the car again I got codes P3030 and P3001.
This car has an extensive service history, It has a new Cat and exhaust, a new accessory and HV traction battery that are less than 8 months old. Crank position sensor is new. fuel tank is new.
What could be causing the P3030 and the P3001?

I am working on my folks 2003 gen 1 prius. Dealer told them inverter was bad so I bought a used one to replace it from junk yard. I was able to drive the car on purely gas mode prior to replacing inverter. I have now replaced the inverter and innitially was able to drive it on battery power, but no gas engine, it wont start. Now no movement at all. I have reset codes both with my obd2 scanner and by the touch screen diagnostic window. Am I missing something here as I can't get the warning orange triangle to go away or check engine light, and now gas engine. When I turn key, I hear clicking sound in rear of car. Also, I left doors open when working on car and drained little battery, I replaced it with a larger battery that I have put in a battery box.

I have a 2005 Prius with 120,000 miles on it. Today the red triangle light and circle warning lights came on. The service department at my dealership said, "inverter converter losing function. No longer able to accurately control voltage". The car seems to be running the same as it always does.

Prius (Gen 2) :: 2008 / Inverter Coolant Pump Leak?
I'm a new owner of a used 2008 Prius. Car only has 67K miles and other than the leak, appears to be in good shape.
I noticed the coolant was low in both reservoirs, filled it up (with the proper SLLC), but a day or so later the check engine light came on. Took it to mechanic (dealer is 2 hours away), he read and cleared the codes, then found the leak. Appears to be leaking where the lower hose attaches to the pump, so not sure if it's the pump or the hose that's the problem. I've also noticed that the pump seems a bit noisy for a few minutes after shutting off the car (of course, I'm new to the Prius so not totally sure what "normal" sounds like).
Prius (Gen 2) :: Removing / Installing Cables From Inverter To Transaxle?
I have an 06 Prius that I got needing a transmission. I picked up a used transmission from the junkyard, and I started working on it today, but I am having a problem. The big orange cables that go from the inverter to the transaxle have been cut. So I need to swap over my good cables (from the bad transmission) over to the new transmission. I need to know how the cables are removed/installed from the transaxle side. They don't seem to want to pull out.

The inverter failed on my 2010 Prius. Toyota had recalled this on previous models, but not the 2010 Gen III.. When it fails the car shuts itself off while you are driving. Luckily I was not on the freeway but was still nearly rear ended and was lucky to get off the road with no power.
