Prius (2004-09) :: Panel Alarm Lights Go On And Power Lost - Inverter Failure?
My 2008 Prius (111,000 miles) had all the panel alarm lights go on and lost power while I was driving on the freeway. After turning off the vehicle and letting it “rest” for 10 minutes, it restarted with only the red triangle alert light remaining on and was able to drive to my dealer service (about 40 miles) with no incident. The diagnostic code indicates that the inverter has failed, but the technicians are not able to confirm that this is the problem, since the system is now running. I was able to drive it home with no problems or warning lights. As this is a $4,000 part, I would like to know if this is a likely, or even possible, scenario for an inverter failing, or could it be another problem? Note: 3 months ago the auxiliary battery was replaced following the same circumstances.

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.

My 2007 Prius with 162k miles had an Inverter Coolant Pump Failure Monday 6.5 hours from home when my wife was driving it home from a trip. Red Triangle, (!), vsc, and check engine light. She was able to make it about 20 minutes to a dealer where it was diagnosed. Luckily no further damage was done to vehicle. Yes, she should have stopped but continued on since car was driving OK.

I own a 2006 JDM prius with 323,000 km. The inverter coolant pump failed recently (got P0A93 code and no agitation in coolant reservoir). I ordered a replacement on eBay and am awaiting arrival. I may need to do some light driving in the in the interim and am thinking about installing a 10 inch fan in the space between the inverter/transmission and radiator to keep things cool. Is this wise or should I just let the car sit until the new pump gets here?
Also, I am burning oil...I usually have to top up 1 to 2 quarts in between changes. Is there anything I can do without tearing down the engine? A friend of mine suggested using Lucas oil stabilizer the next time I change oil...could this have any negative implications?
Prius (Gen 2) :: Inverter Pump Failure - Code P0A93
While driving home last night the Red Triangle, CEL and the Hybrid Warning lamp, (on the MFD) all lit up. The cruise control also shut down. We stopped and checked the manual to identify what the symbols meant. We were approximately 90 miles from home, drizzling rain and it was about 60 degrees.
View 18 RepliesPrius (2010-12) :: Check Hybrid System Light Came On - Inverter Failure
2010 Toyota Prius III with just under 60,000 miles. The car has been serviced at Toyota from day one (by us and by the previous owners) and runs like a champ. Well, did.
Last week while driving home from running errands the Check Hybrid System light came on for my wife. The car was still running so she drove it home for me to look at. I hopped in and noticed the gasoline engine wasn't turning on. I took it for a spin and even when I floored the car the gas engine wouldn't turn on. Since the nearest dealership is 15 highway miles away I knew we weren't going to make it there on electric power so I had it towed.
The Toyota dealership called me the next day saying when they started the car the light was gone and the car ran fine. They did some troubleshooting and found nothing wrong. They said it might have been a glitch and to come get the car. Not even 3 hours later the light turns on again. Again the gasoline engine goes silent, but this time I didn't even make it a mile and the electric power shuts off as well! We coasted to a stop and had to have the car towed again. This happened out of nowhere and could have been a very serious safety situation had it not happened on the road we were on.
This time the Toyota dealership had a little more to say. They said that their diagnosis has determined that the inverter is shot and they will have to order a new one. They said this failure is extremely rare (the service guy I spoke with had never seen this issue).
Prius (2004-09) :: Recurrent Power Failure After HV Battery Replacement
I have an 05 Prius which had no significant problems until the HV battery died this past Feb. Two days later, I'm on the highway and lose power, manage to get the car to an off ramp. Have it towed to a dealer where the power failure pulled up code DTC P3190 and I was told that the car was simply car out of gas. The car was at 3 pips without any indicator going off but after consulting this forum I thought "Okay, maybe this is just the new normal." Filled my car with 5 gallons worth of gas which topped it off (?) and went on my way.
I'll add here for lack of a better place that with the new battery the car has not ever seemed to accelerate cleanly - always feels like there's some resistance on the accelerator when trying to go above 50 on the highway.
Cut to yesterday - I lost power on the highway 3 miles from home with the car at 7 pips (!). I had only put 130 miles on the car since last filling the tank so I can *not* imagine this is a fuel issue. And, worse than ever before, this time when the engine failed I had only about 1000 feet to get over to the shoulder. I did manage to get over safely (for those in SoCal, this was on the 5 North and I narrowly missed blocking the ramps to the 134). To make matters even worse it rush hour in 95+ heat, and I was pinned in my car for 20 minutes (traffic on one side, retaining wall on the other) until the tow truck arrived. I cannot have this happen again.
I had the car towed to the dealer this morning. When the car was picked up the car was at 7 pips in my driveway. The dealer states when the car was dropped of there it was at 1 pip, and sent me a picture of the odometer to verify. Wth?!
How is this possible? How could the gauge have dropped so rapidly? Is there a legitimate way the fuel indicator could have dropped so much or is the dealer scamming me? And what could be be wrong? The AAA driver this morning said they should have replaced the accessory battery when they replaced the hybrid battery, and perhaps that was the source of the problem?
Prius (2004-09) :: Combination Meter Failure And Loss Of Brakes / Power Steering
Faulty combination meters on the Toyota Prius. Loss of braking and power steering on the vehicle? This has happened to me 4 of the 100+ times my dash lights were not working. On those 4 occasions I was driving without the dash lights and all of the warning lights came on and the car lost power steering and the ABS braking and I had to use the emergency brake to stop. Fortunately when this has happened I have not been on the highway and there was no snow or it could have been very dangerous.
This issue has only happened when there is a malfunction with the combination meter. I understand this can create many issues within the vehicle including braking difficulties. The response of the Manager at my local Toyota shop said "well, at least you have brakes, you just won't have them in an emergency stop." Wow! I've read accounts of people going 65 mph and losing brakes when this has happened which could be very deadly.
I'm surprised at Toyota's response with this possibly deadly issue. I'm also surprised that the Combination Meter Failure has not be recalled because based off what I have read about 3% of Prius owners have experienced issues with this and the braking system. At what point does a "warranty" become a "recall"? Please note that this issue is separate from the "accelerator recall".
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 (2004-09) :: Inverter Pump Noise - No Circulation
I have a big red triangle on the pump is making noises not loud noises sounds like it's operating correctly there is no turbulence in reservoir and when I squeeze the hose the level in the reservoir goes up-and-down which leads me to believe there is no blockage in the pipe coming out of out of the pump.
My handheld scanner and torque on my android tablet only gave me my oxygen sensor code which I know about and I'm going to replace when the weather gets hot I am wondering if the coolant pump would throw a code that these devices would be able to pick up or do I need to go to the dealer or find a shop which is capable of reading the HYbrid codes?
Prius (2004-09) :: Inverter Stopped Working - Replacement?
I have a 2004 Toyota Prius with 150k miles. Yes, 150k miles ... Anyhow it basically stopped working and the dealer said its probably the inverter that's throwing the code. Does the 2004 inverter is replaceable by all Gen II inverters? The dealer says 2004-2005 is different than 2006+ but eBay sellers don't think so. Can I run any 2004-2009 Prius inverter in my 2004?

View 8 RepliesPrius (2004-09) :: 2008 - Hybrid Inverter Won't Working?
My 2008 Prius wouldn't start a couple of days a go. Took it to the dealership. The tech said he got the code reset, but couldn't get it to fail again. It is clear for now, but his experience tells him it will fail again, possibly in a few months. The code said the Hybrid Inverter was bad. Thy hybrid warranty ran out 2 months ago. I have only 67,000 miles on the car. It has been trouble free up to this point. This still means I would need to pay for a part that shouldn't fail, and was in warranty just 2 months ago (8 year/100,000) with only 67,000 miles on the car. What should I do? Wait to see if it fails again?
