Prius (2010-12) :: Check Hybrid System Light Came On - Inverter Failure
Jul 17, 2013
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).

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?

1,500 miles ago my car had it's 30k service. Today, i got "CHECK...". At home this evening i checked the inverter coolant reservoir, it was empty. I've added 1L of de-ionised water (which got it to full, and i see turbulence in the fluid) until i can get the correct fluid.

I have a 2013 Prius Persona with about 5,300 miles on the vehicle. Just recently had the 5,000 mile service taken care of at a local toyota dealership. The very next day I tried to start my vehicle with no prevail. My instrument panel indicates "check hybrid system" (!) the car will not start, nor will it shift into drive or reverse, only into the neutral position. Made several attempts to turn vehicle on and off and tried to jump start. Still no luck. Had the car towed back to the dealership. Mechanics are still trying to identify the problem. What may be the cause?

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.

I was driving, when out of the blue my car went into neutral, and the dashboard lit up. Then all of a sudden the light stayed on "check hybrid system". I pulled over to side of road. AAA towed me.
THIS SHOULD NOT HAPPEN. NO warning.

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.

Check hybrid system light came on and the whole dash lit up like a christmas tree. After i jumpstarted the 12v battery when it died. It was driving fine for about half an hour and all of a sudden the lights came on during acceleration from a stop light.

I have a 10 month (15,000 mile) Prius and the " check hybrid system" warning light came on while driving on the interstate. 17 miles later the car quit running. I had it towed to the local dealer and after taking a looking at it I was told the error code pointed to the water pump (which they plan to replace). Does that make since? Has this been a problem for the Prius IV?

I was curious how you can get rid of an annoying "check hybrid system" dash warning?
Let's just say I know for certain nothing is wrong. It's only cause I accidentally disconnected and reconnected a wire. Just need to reset is all.

I have a 2015 Prius package two. The other day I was taking it in for its 10,000 mile maintenance, and I pulled out a fuse that I connected my DRL lights with the Main power (so the drl lights would be on with the head lights). The car was on and the check hybrid system light came on. The car would not move only stayed in park and neutral. I had Toyota care come pick it up and they said that if there's any issues that the warranty won't cover it. How I can get the warranty to cover any damages if there is any. The tow truck driver said he thought the car Might think it's being stolen because I did unplug the battery for about 15 minutes to try to reset the check hybrid 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.

Just started up my car and the "Check Hybrid warning system" came on, along with a check engine light. The car starts and moves, but I'm unsure if I should drive it to the dealer two miles away without doing any further damage to the vehicle or have it towed. The car has 130000 miles and is serviced every 5000 at the dealer with all recommended maintenance performed.

I have this Prius involve in a wreck on the driver side. Ever since the wreck the hold beeps continuously, "Check Hybrid system turns on". I drove it couple of time every things was fine ( see the video) now nothing comes on. After the wreck I had to jump every time I wanted to start, but now nothing even after multiple jumping attempt, the battery used to die because the brake like always stays on and as soon as I start the car the horn keeps on being non stop.

I cleaned out hybrid battery cooling fan today, not too bad after 160K . However, as I test drove prius the Triangle of death and "Check Hybrid System" message pops up.
Drove 13 miles back home, battery charged good. No power consumption data given on hud. Rechecked fan connection and looked over area. All looked good. I dont think ICE was running during drive home. Tested 12 volt=good. Disconnected 12 volt and orange plug. Reconnected. System reboots and seems Ice goes through warm up. Even put in power mode and it roars. Scratching head on this. Coincedence or maybe I should have disconnected 12volt before disconnecting cooling fan?

Just got a "Check hybrid system" message and the triangle of death is on my 2010 Prius -- but I can still drive it...
Toyota's Emergency Response Guide says this error is triggering by the ground fault monitor that is connected to the 12v aux battery.
HV battery pack ( HV battery fuse, two 12v relay)
HV battery inverter/converter

A few days ago our 2010 with 87k became immobile with "Check Hybrid System" illuminated on dash. Dropped it off at the dealer who had it all day. Replaced the "transistor kit" part number 04899-47021 and blamed the failure on the recall. Recall was not completed. Wife felt a jolt while driving home but no warning lights illuminated. Next day she tried to start it and got that message.
Codes pulled were p3004 with info code 800 and p0ad.

We bought a used Toyota Prius 2012 with about 35,000 km in early August 2015. We shipped it overseas. It gives the "Check Hybrid System" error when we try to start it. All the lights and instruments work o.k.
I've read this car be a problem if the car is parked a long time, which it was as it was mostly in a shipping container.

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.
