Prius (2010-12) :: Check Hybrid System Warning Light Came On While Driving
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?

This afternoon, after driving about 150 miles, I came home and shut off my 2001 Prius. It was sitting for about 20 minutes before I turned it back on to drive off. Almost immediately, the hybrid warning light came on on the MFD, the red exclamation mark light illuminated, as well as the check engine light, and the motor shut off. I popped the hood, and could hear a high pitched squeal coming from near the inverter. I called my dealer to ask the service department what I should do, and they just told me to bring it in and they will take a look at it. I live over an hour away, so I don't want to bring it there if I can avoid it. I then shut it off and let it sit for a few hours.
After reading about the possibility of the auxiliary battery being bad, I went and turned the Prius on, and then shut it off several times to reset the hybrid warning light (I had to do so in order to access the aux battery information through the MFD). It turned on without incident, and shut off fine, and after being reset the hybrid warning light shut off, as well as the red triangle light. Then, I went through the process of pulling up the battery voltage information through the MFD.
With the car off, and the lights and fans off, the battery voltage read about 10.0-10.5 V. With the lights and fan on, the voltage dropped to about 9.5 V. After getting those readings, I drove it down the road a little ways, just going about 20 mph. It seemed to work fine. The check engine light is still illuminated. With the motor running, the voltage reading was 13.2 V, and then when I got back from my test drive and shut it off, the voltage hovered at 10.6 V with the lights and fan on.
Prius (Gen 2) :: Red Warning Light Regarding Hybrid Battery While Driving
But while driving the hybrid warning light turned on in the MTD. A red car if I remember correctly. It was the hybrid battery over heating and to try and mess with the wiring going to the cooling fan in the right rear quarter panel.

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.
Prius (2010-12) :: At 15,000 Miles Hybrid Warning Light Came On

I've got some issues with my 2005 Toyata Prius (~150,000 miles). My wife was driving recently and the "Master Warning Light", the "Hybrid System Warning Light" and the yellow "Brake System Warning Light" all came on.
Some quick reading of the owners manual said we should take it to a dealer right away, but because it was a yellow, and not red, brake system warning light it seems ok to drive at least to a dealer. in regard to the yellow brake system light the manual said it could be that: "the regenerative brake system failed or that the hydraulic brake system failed".
Now, I have a cheap bluetooth OBD reader hooked up to the "torque" app on my phone and I thought I would try to see what error codes there were to learn more. But strangely, it did not read any fault codes. I've used this reader successfully on my 2001 Mitsubishi galant, but I'm not reading anything for the prius in this case. I'm not sure if there is legitimately no error code associate with the warning lights or if my app is just failing to read them for some reason.
Prius (Gen 3) :: Check PCS And Hybrid System Warning While Driving At 68 MPH
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.

Our winter tires on the 2010 prius have the pressure sensors insalled in the wheels. Yet, ever since they were installed, the tire pressure light has been on on the dash. I have checked the tire pressures numerous times, and they are okay. In fact I now have the tires slightly over inflated instead of at spec, and it's still on. Do the sensors go bad in the wheels? We've had no issues with the system with the summer tires and wheels.

Quick Question: I was driving through my neighborhood yesterday and hit a pretty good bump. I as hit the brakes, a quick Yellow Triangle Light illuminated on my dash. There were no other warning lights that I could see and the warning light was only on for a split-second. What could've caused this? BTW, I have a 2013 Prius LB 3 purchased new in August w/ only 1230 miles as of today...

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.

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.
Prius (2010-12) :: Yellow Triangle And Check Hybrid System Warning
First off I have a 2010 with about 11,000 miles and it has been running great since I got it. This morning I was greeted with the "Yellow triangle" and the "check hybrid system warning". The car started fine and I pulled out of the garage under battery as usual and then the engine kicked in also as usual, everything seemed normal except for the warning lights. Since I have a long commute I just took my wife's car and got to work and did a forum search on this issue. I called my wife and had her turn the car on and off three times and she said it cleared the yellow triangle and check hybrid system but it still had the check engine light on. She also said the car seemed to be running fine and shes driving around town in it. I couldn't find anything on the check engine light. Is it ok to drive it?
View 3 RepliesPrius (2010-12) :: Check Hybrid System Warning Came On And Speed Reduced To About 40
Tonight I was driving my 2010 Type 2 Prius. I had been driving for about 6 miles in 85 degree heat (after the car was parked all day at work) on the freeway at 60mph when the "check hybrid system" warning came on and my speed reduced to about 40. I pulled over and called a tow truck. After I was towed to a dealer about 25 miles away, the car started up without the "check hybrid system" light coming on. However, the check engine light did come on. My car is low mileage with only 31,000 miles on it.

The last few weeks I've been noticing that, upon start, the hybrid battery is showing at 1 line. It's been really hot in SO cal and the air con has been blasting, so I've been letting it charge up a bit before driving. Once I'm on the road, the battery charges fine and seems to hold a charge.

View 19 RepliesPrius (2010-12) :: All Dash Warning Lights Came On / Check Hybrid System Message
My Prius yesterday while driving slowly (under 10 mph) all the dash warning lights came on(triangle, cel, trac control, brake). the gas engine started and the message came on that says: "check hybrid system". Today when I went out to check there only two warning lights on (triangle and cel) with the same message displayed. My question is can the vehicle operate without damaging anything if I drive it as is? I have read on several threads that the engine will not start if the hybrid motor(s) are not working. Since my engine starts and runs I have to believe the motor(s) are working.
View 19 RepliesPrius (2004-09) :: Getting Hybrid System Warning Light?
My wife just called and said this light came on. She said when it came on the car turned off its cruise control but kept running. Now she says it seems to be running fine but the light is coming on.
The car has around 110k miles and I just replaced the spark plugs, air filter and engine oil about 1k miles ago. What it could be? I'm going to have her pull codes at the auto parts store but she needs to do about 20-30 miles of driving today for work. Is it safe for her to do so?
Prius (2001-03) :: Hybrid Warning Light And Dies Soon After
About a year ago when driving on a 3ish hour trip, I made it almost to my destination and the hybrid warning lights came on. I noticed my windshield wipers were moving extremely slowly, and about five minutes later the screen and all the lights flickered off, the power steering went out, and I came to a dead stop on the side of the road. After calling a friend to come rescue me, they arrived and for fun I attempted to start my car and it ran fine, and the next time I drove it all the lights were off. I drove it for several months afterwards with no problem. It happened again a few months later and I took it to the dealer who "completely disassembled" my car and said they found nothing wrong with it.

I was driving to work yesterday and all of a sudden the "Hybrid System Warning Light" just came on the screen. I didn't notice anything different and drove it the same way. However, when I checked the energy monitor screen, the battery was low on charge. It came back to normal in about 5 minutes, but the light is still lit up.
View 9 RepliesPrius (Gen 2) :: Red Hybrid System Warning Light / P0A93, C1300 Came On
My 2007 just came due for an oil change a week ago (Maint Reqd stays on), not that it matters. Yesterday the Red triangle of death, Check Engine, and brake warning lights came on. We drove another 15 minutes (city) without incident. When I turned the car back on the brake warning was off (and has stayed off) but now the Info Display has the red Hybrid System Warning Light also showing, along with Mr. Triangle and Check Engine.
This morning Autozone read out the P0A93 (confirmed) and C1300 (current) codes for me. With the car "Ready", I can see fluid movement in the inverter coolant reservoir (not sure it qualifies as "turbulence") and feel vibration in the line connected to the pump which is humming so quietly. The 12V battery shows 12.5V with the car off and 13.5V with the car on. Does this mean the inverter is still operating? (I read the P0A93 code is supposed to shut it down.)
I did find the ICE coolant reservoir dry and refilled it with SLLC. There looks to be a small leak in the water pump, but I'll deal with that later.
