2004 Prius - Inverter Pump Failure

Some of the 2010s have this problem also, different pump same problem. In the case of the 2010 they have issued a TSB. It would be nice if Toyota would stock the parts that they know are prone to failure.

I am planning a trip to the Southwest desert country this fall. I sure hope I'm not stranded 1500 miles from home with no parts available to fix the car.

If you do a search of the Gen2 forums you will find other Gen2 owners who have had this failure also.

:welcome: BTW welcome to Prius Chat, wish it were under better circumstances.

 

Feeling your pain !

My inverter coolant pump went out on my 2005 @ 82000mi this week while I was on the way back from CA (I live in AZ). Now it is stuck at a dealership 4 hours away. The repair tech keeps telling me that the inverter pump is on national backorder and no nearby dealers have any. I finally found one at an AZ dealership yesterday and Fedex-ed it out there myself. We'll see how long it takes to get installed and what else has been damaged. The parts guy here in AZ agreed that this is a "rare part".

Reading this forum, I can see that folks have been reporting these pumps failing and on backorder all the way back to 2007 (probably earlier).
You'd have a hard time convincing me that any "world class" auto manufacture couldn't figure out how to boost their supply of a problem part in 3 years time !

Something is very wrong with Toyota here - not a confidence builder at all !

 

There is an old TSB on the Inverter Coolant Pump for 2004 and early 2005 Prii. The design of the pump has changed so the new one should be more reliable. I replaced mine at 150k miles when changing the coolant (for the second time) to avoid a problem on the road. The dealer had no problem finding the part as it was in stock in the parts department.

Welcome to PC, though it's on a sour note. As the inverter pump is part of the HSD system, I'd find out if it falls within your hybrid's 100,000 mile warranty. It's not just the traction pack that gets warranted for 100K miles.

 

Inverter pump died last Tuesday (Aug24), hot day in Phoenix, Riverview Toyota said part was not available in US, back-ordered with eta mid-September. I found a new one on ebay, got it Friday, will install myself today. My Prius has 65K miles. I guess you need to carry a spare.

 

Wow, failed two days apart & we were searching in the same area (found one at Big2 in Chandler). Glad you got it!

IMHO this shortage highlights pathetic supply chain management by Toyota/Denso.

 

Nope, the inverter coolant pump is not covered by the hybrid system warranty, though it seems that it ought to be.

 

It is, however, covered under the 5 year powertrain warranty.

 

Sorry to hear the news on the delays.

For me, it was quite the opposite. This past Friday evening while out driving with the family, "Bam!" red triangle & 2 other warning lights appeared suddenly while driving 70mph on local freeway. There was nothing to indicate something was broken other than these new warning lights. Still, I headed for the local dealer not wanting to take any chances of being stranded. While driving the car to Tustin Toyota, I noticed that the AC must have quit as the air blowing was no longer as cold. Within 10 min, the air was definitely not "air conditioned". I turned the car in around 8:30pm (service open until 10pm luckily). I feared it was going to cost an arm & leg since my car is out of 3yr/36K warranty. Early the next day, they confirmed it was the inverter pump that went bad, but that they had "Great news!"...

My car is '06 and had 59,970 miles which falls under the "power train" warranty of 5yrs/60,000. Talk about breaking down at the right moment.

Net price = $0.00

They called me back 5 hours later with the new inverter pump in place. AC blows cold just like before warning lights. Counting my blessings... I hope your Prius gets fixed ASAP!

 

Absolutely amazing timing !!! Great to hear.

FWIW: I picked up my car last weekend & put 1500 miles on it driving through the sierras with no issues. It acted a little strange (engine revving) once or twice but I think that was the long hills cycling the battery up and down. After all that, I think it's fair to say the car is fine.

 

I have a 2007 with the same problem; inverter coolant pump failed. I got the code with my ScanGauge, P0A93, cleared it and it threw the same code again within minutes.

I took the car to my local dealer here in the Dallas/Ft. Worth area and they confirmed the pump had failed. They told me it was on national backorder. Sadly, it took 3.5 weeks to get mine repaired and returned. My dealer kept me informed on a regular basis and provided me with a loaner car (very nice and unexpected.)

Vital stats about my situation:
The failure occurred at 67,000 miles.
It was covered under my extended warranty. I had a $50 copay.

The line items on the invoice:
CMAP $210 (labor, I presume)
G9020-47031 pump assy, water w/m $116
00272-SLLC2 super long life cool $20 (presumably the coolant)

They also performed 90L special service campaign for potential floormat interference with accelerator pedal. I wasn't charged for any of this other than my copay.

I hope the part numbers help. If your Prius is getting close to 60,000 miles, you might consider doing a preemptive strike and order the part before you need it. Keep in mind mine is a 2007 Gen II. Your part number and mileage may vary. lol.

 

Hi everyone: First post here. I have owned 4 Prius' going back to our first purchase in 2011. All 3 of my older Prius 2004 x2 and a 2005 had to have the Inverter Pumps changed over time. Typical cost with new inverter, coolant, and labor $475-$525 depending on my shop that I am friends with and how generous they were feeling that day. Besides the tail lamp assemblies, headlights, 12V Battery, 1 muffler, driver window actuator, and rear coils on my Prius, and regular maintenance...I am making out on car ownership expenses. Bought all 3 in cash deals $8,000 - $6,000 - $1,200 [family member discount as they bought the 2005 new and drove it forever and sold to me for my daughter.] I get mileage for my sales job, which pays for pretty much all 3 of my Prius while everyone else drives $60k vehicles with a mortgage payment on them.

 

That nice but why not start a new thread rather than comment in a 9 year old one?
