Prius (Gen 3) :: Hybrid System Overheating - 12v To Be Replaced
Mar 7, 2015
I have a 2010 IV Prius that has been having the following issues starting up / turning off:
On February 4th in the evening: car wouldn't start. Started on 5th try - showed "HYBRID SYSTEM OVERHEAT."
On February 15th in the evening: car wouldn't start. During multiple attempts to start hybrid screen to the right of speedometer flickered / went in and out and was faint. Started on 5-6th try.
On February 16th in the afternoon: car wouldn't start. Hybrid screen to the right of speedometer flickered and went in and out during startup attempts. Eventually car started at 5-6th try - but display to the right of speedometer did not come on at all. Car felt like it was running on engine only.
Took car to Toyota dealership. They had it for 2 weeks and could not figure out what the issue was. Car did not show any error codes. Said they did not experience issues either. Gave me the car back.
On March 3rd, as soon as I got the car back and while still in the dealership parking lot, I pressed the start button with my foot on the brake and only the AC / radio came on. Called over service advisor and when he came tried it the car started up fine.

2006 Toyota Prius, bought new in Oct 2006, currently at 90,000 miles.
It just recently broke down on me about a month ago, the dashboard lit up like a Christmas tree with every possible light flashing and nav screen showing "problem." I took it to the Toyota dealership and they determined it was a hybrid system fail and replaced the battery.
After this, I'm thinking all is well. I go out of town this past weekend 130 miles away from where I live and day 2 into vacation my dashboard lights up again! Same lights, flashing red triangle, Vsc, check engine, etc. it gets me back to my hotel but the next morning the engine won't start. At least the first time it broke down the cars engine worked and was somewhat drivable.

I have a 2010 Prius, currently at around 69,000 miles. Back in Feb 2015 (when it was just under 60,000) I was driving on a city street and hit the accelerator once a stoplight turned green - immediately as I took off (at a normal rate of acceleration) my 2010 Prius made a loud noise and I got the red triangle of death, with a "Check Hybrid System" message. The car quickly shifted into "limp home" mode and I was able to make it back home as I was only about a mile away.
Got towed to the nearest dealer the next morning and after tons of testing and going back and forth, they replaced the transmission and inverter (was able to get it covered under powertrain warranty), and I was on my merry way. No issues until last night.
Yesterday evening, I am on a city street and get a warning beep. I look at my dashboard and this time I have a yellow exclamation mark with the "Check Hybrid System" message yet AGAIN. Towed the car to the nearest dealer and am now waiting on next steps. Only update I've gotten so far is that they are still trying to diagnose the issue, and are getting 4 error codes in this process, 2 of which are new. I am waiting on the technician to tell me what the actual codes are - hopefully should get them tomorrow.
I would hope if it's another issue with transmission or inverter, it's covered under warranty given I replaced both less than a year ago. However I'm not sure and am worried that it's going to be $$$ in case it's something else that failed. Plus I'm getting serious doubts as to the safety of my car - what if I had been moving at a high speed on the highway during either of these situations?

Actually 2 very similar questions about my Prius 2007.
1. My water pump was replaced by a dealer due to failure some half a year ago at 95,000 miles. Yesterday, after oil change (98,000), I was told it is recommended to replace engine coolant. Does this sound right? Don't they change coolant when replacing the pump?!
2. Identical question about HV pump. It was replaced at 80,000. Now they recommend do change the coolant for hybrid system. Don't they have to do it when replacing the pump?
I want to do everything necessary to maintain the car. But don't want to spend money for something that is not needed.

I have a 2005 honda civic. About a month ago it started overheating. Drives Ok on the highway but heats up to the H mark almost as soon as I get off the highway. Have replaced the water pump, thermostat, radiator, flushed the system, most hoses, fan, 2 sensors, timing belt, spark plugs and had the head gasket checked 3 times by 2 different shops. Both said it was fine. The mechanic that has done most of the work is baffled. Says he has never seen anything like this and is at a loss as to what to do next. I am supposed to drive this car halfway across the country in a week to meet my husband who is in the air force. Should I just sell this piece of junk!?

Two weeks ago a large, industrial truck dropped a piece of bent steel pipe on the interstate in front of my 2010, 50k miles, Prius and (sadly) I was forced to hit or swerve into rush hour traffic and cause an accident. It tore up a good part of the cooling system and did some body damage. Of course I didn't know this at the time, but it began to overheat, so I pulled off the freeway and had it towed to a body shop. After about ten days, I got my Prius back.

I just switched out my hybrid battery and put in a brand new one. Now, the car isn't doing anything and all that's on is the check engine light. What now? I was told I had to tow it to Toyota and have them reset the computer. Sound right?

I have 2005 Prius with 300k miles. I started throwing P0A80 code. I removed the battery and checked all the modules and found 2 of low voltage, ordered them from Ebay and replaced them. I placed the battery back in the car and started the car but got P0A80 code again. I purchased the grid charger from Hybrid Automotive and connected it according to their instructions for 24 hours. I drove a car but got the red triangle again and P0A80 code again. I removed the battery again and tested the voltage of all the modules and these are the readings:

My husband just replaced the spark plugs in my 2005 prius with 174,000 miles (also replaced the right headlamp bulb). When I started the car, the PROBLEM check engine light Hybrid Warning Light came on.
Owner's manual says take it to the Toyota dealer. The dealer is 50 miles away. Is it safe to drive it the 50 miles? It drove okay up and down my driveway.

I had my hybrid water pump replaced (free, under recall) about a month ago. Now the check engine light comes on intermittently, and it's with error code 1121 (Coolant flow control valve sensor stuck). I've seen other people on this forum hypothesize that the work could cause this error (if not bled properly, leaving air in the system). But my dealer said the work had nothing to do with this error and I need to replace the control valve. How to suggest to my dealer that it could, in fact, be due to their work and that I think they should fix it for free?

This video is about the Toyota Prius Gen 3 Temperature Indicators and cooling system overheating. I thought the prius did not have temperature indicators but found out it did, so this video is about how to know if your toyota prius is overheating and understand the basics of its cooling system.

I just bought a used 2012 Toyota Prius iTech from a country town 3 hours away. About an hour into the drive home, the display informed me to "Check Hybrid System" and then "Check PCS System". The car continued to function for a little while, then eventually lost acceleration, so I pulled over. I turned it off and on again; the warning light remained but the car started and continued to work, but soon after I lost acceleration again. This happened one more time.
Then I Googled the problem and discovered that you could "turn it off and on again three times to reset the computer". I did this and the problem disappeared and did not resurface for the remainder of the trip, and has not happened again since.

I was trying to install the invisicord cable for my escort radar detector thru the auto dimming/homelink mirror, I shorted it and homelink no longer has any power, a couple minutes later i got a check hybrid system.
Now question how do i restore power to the homelink mirror, is there a fuse to replace? And that warning and all the other warnings that i got related to the short. I read somewhere here that if power to the homelink mirror was off that you get no power to some systems, not sure where is that post, cant find it the car starts.

So a little over a month ago, I was driving my 2010 Prius (about 42k miles) when the Check Hybrid System light came on. I lost power and my car was stuck on the road, as I was unable to get it into neutral. So I called a tow truck and was towed to my local dealership. The dealership ran some tests, thought it might have been the throttle body. They switched my throttle body with a loaner prius to see if this fixed the problem. The new throttle body worked in my car and my throttle body was put into the loaner and functioned fine. Then they ended up fixing a TSB for the electronics in the car. I was told the problem was resolved and I could pick up the car about a week later.
After picking up the car a week later, before I could even drive away from the dealership, the Check Hybrid System warning came on again. I talked with the service manager and left my car to be fixed again. They checked all the systems and were still unsure what the problem was. Eventually they made sure all the connectors were properly seated and test drove the car and ensured the problem was gone. About two weeks later, I was told the car was fixed and I could pick it up.
After picking up the car, I was still unsure the problem was fixed, but I was told that was all I could do. After having the car, for about a 1.5 weeks I was on the highway. Once again, the check hybrid system light came on and I lost engine power. Luckily, I was able to pull over from the left lane without causing an accident. Once again, I had the car towed to the dealer and now I am waiting to hear back from them.

2013 Prius C THREE 67k miles
Got out of my car after using it friday. hopped back in to go to work tuesday was getting," Check Hybrid System, stop and pull over immediately". I put about 30k miles a year on my car so i run it hard and I am probably due for oil change and tranny fluid drain and fill but other than that because the car was working fine friday. I tried going into accessory mode then holding brakes and powering up, I forget what that's called, but no luck
Towed it to my mechanic, he said that he was getting generator errors (and tsp or tsb things?) and that he could most likely do the work but that I should make the dealer do it because it may be under warranty and didn't charge anything. So got it towed to the dealer and after the hybrid tech got in they said they see some generator error but they can't reset it. But also mentioned they got the car to come on.

my 2010 Prius III was working fine yesterday, but today when I try to start it it did not start. no green or abmer light on the push-start button. I tried few times, but no luck. I got the key from my pocket and got it closer to the push start button and I start hear the normal noise that happen when I opn the door, but the noise was very low and the internal light was very dimmed as if the battery dying. after few attempt to start, the car start at last, but the hubird screen where show the system on the dashboard was off. I try to change the display of the hybrid system but nothing start. the GPS screen display "no DVD MAP inserted" and seem frozen and not allow me to turn off the screen or press any other button.

I was going through a bad day today with my 2010 Prius Gen 3. I was on highway driving at 68MPH behind another car, at the time I step down on gas pedal for overtaking, all a sudden both "Check PCS system" and "Check Hybrid system" appears on the Console display and gas pedal had no response from the engine at all. The car was not moving and I had to stop aside and "P" the car. I tried to turn off the car, turn back on more than 10 times. Both warning signal "Check PCS system" and "Check Hybrid system" display on console and the car can not go into "ready" mode hence the car can not drive. I could put shift to "P","N" but just not "D". Had to call tow truck to tow back to toyota dealer, and they said will look into it on Monday.
