Prius (2010-12) :: 2011 - Dash Board Yellow Warning Lights Came On
Jul 24, 2015
This morning when I started my Prius 3rd Gen 2011, I noticed three yellow lights being on. These were; something similar to handbrake light, ABS light and then the stability control light. All are in yellow. Checked tire pressure and found that one tire was low and filled it. Also, brake fluid was near the low level and I topped it. The lights are still on. I switched on and off several times but the lights are still on.

My car (2006 Prius with 250k miles) was operating normally all day today. Still getting very good mileage around 52 mpg on average. Then abruptly, the big red triangle and few other yellow warning lights (check engine, VSC, and an indicator with exclamation mark in the middle) showed up while the car was moving around 20 mph.
Now, the car does not have much power and it was very difficult to speed up or going uphill. Turned the engine off and then back on. The symptoms still persist. The battery indicator was at only 1 bar. Let the engine run for a while and the battery indicator went to 3 or 4 bars. Turned the car off and then back on, the battery indicator went back to 1 bar immediately. Also the battery fan was running at high speed, even through I have just started driving for about 5 minutes.
Will do the following tomorrow:
(1) check 12v battery,
(2) use Torque SW to see if HV battery has proper values, and
(3) read diagnostic codes.

Last week I bought a 2006 Prius. Two days later I heard a noise brought it to a Toyota dealer and they replaced the right front wheel bearing. The noise stopped. Then about 40 miles later on an interstate the General, ABS, and VSC yellow warning lights came on. I to it back to the dealer (the lights went off when I got off the interstate) and they cleaned an external connection and but said there could be some grease inside and the light could come back on but it was safe to drive. I proceeded and the light came back on. The lights stayed on while driving it about 1,000 miles home.
Then in the morning after the lights came on after driving it about 15 miles, I again to it to a Toyota dealer and diagnose the lights and a little to fix it, Ten 5 miles down the road the lights came on again. I drove back to the dealer and they said something like: "There is a lot of rust on the rotor etc. that probably was loosened when the wheel being was replaced and that is interfering with the speed sensor. And that the knuckle has swelled.

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.

We've got a 2011 Prius with a little over 24k miles on it . For the last few months we've been having issues with it starting. First I thought the remote barriers were dying so I replaced them , I thought my wife might have been trying to start it incorrectly till the problem happened to me a few weeks ago. What happens is you try to start it (foot on brake, press power button) and all the warming lights pop up , radio turns on , navigation turns on but car doesn't start. This morning it happend just once , yesterday I had to try it maybe 10x before it finally started up. The dealership had it last Saturday and of course it started every time for them and they couldn't duplicate the problem , they also said they ran whatever tests they do on it and it didn't turn up a problem. FWIW we had the software recall update done in June.

My case involves a 2005 Prius with 55k miles on it with the problem of the master warning light (triangle with !), yellow brake light ( (!) ), airbag, and VSC lights coming on whilst driving. The car drives just perfectly fine without any discernible problems. Scan tool did not detect any codes. Tested the 12v auxiliary battery and it is strong with both voltage and amperage (even went as far as temporarily jury-rigging a fresh v12 battery in parallel with it to see if it would alleviate the problem). Inverter coolant pump runs well, coolant changed with appropriate Toyota Super Long Life coolant (50/50 mix) and system bled. Despite some drivers' concerns over disconnecting the 12v battery to reset the lights, this was done and the lights would go out, only to have them come on again after about 5-10 minutes of driving. Asides from the lights coming up, the car itself seems to be asymptomatic. Hybrid system appears to be running smooth and fine, SOC is good, asides from the lights the car drives very well.

My 2006 prius has the Master warning light(red) and the braking system light (Yellow) on while I am driving, and I went to the dealer.
The technician told me that he could not verify any warning lights ON at that moment, and he performed health and diagnostic checks on it. He inspected connection at auxiliary battery and junction box 1. All checked OK at this time. No repairs recommended at this time.
However, the master warning light came on when I pick up the vehicle. The dealer told me that they will inspect it again tomorrow. And they found that there a P0A08 error code. They suggested me to replace the hybrid converter/inverter.. My car can still drive while the lights ON.

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?

Had a warning flash up last night that I've not seen before. Had just done a reasonably long run from an airport with 3 burly guys and their luggage. Just as I was pulling up to their hotel the car did a continuous beep and flashed up the warning "Turn Power Off" and flashed the yellow triangle. When I was stopped I was in Park and it was still beeping and flashing this warning.

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...

This morning I got a yellow warning light flash for a few seconds and then turn solid after driving on the highway for a few minutes. It looks this: (_!_). It is located on the right of the dash display. I just changed my oil and put on winter tires myself two days ago. I hope it isn't related to my maintenance.

I've got up two weekends in a row to this : 20130922_064713_zpsd7701bd3.jpg
All of the warning lights on my dash are lit up. I cannot put the car in gear due to the drive not showing up. The RPM's show 0, then after a few seconds they bump and start working. After restarting car a few times it finally goes away. Everything but the check engine lights. Anything to try before I put it in the shop tomorrow?

Gen III, 2010 Prius III ... There is a flashing yellow triangle, dashboard lights up, but won't start. The dome lights won't turn off, in any position.
Drove it last night and drive it regularly, daily. I came out to the driver side door being not fully closed. What's going on?

I just got a 2015 Prius 4 and during an ordinary turn onto an on-ramp, the engine died. The two yellow engine lights on the left of the panel turned on, but because I had to move along I just turned the car off then on, like a computer and it started right back up. I'm not sure if the electric engine died or not, everything was moving too fast.
I took it in to the dealer today and he said he never heard of that happening and if the engine light hasn't come on since he didn't know about it. I wanted him to log in the info as I couldn't leave the car today, but he said he couldn't do that unless he took it in and had it checked, which I guess I'll do next week.

I had just picked my kid up from school, as I turn out of the parking lot my A/C stops blowing cool air, I check the A/C screen and it still says it's set on High with temp at 68. However, it is blowing very low with warm air. Seconds later the dash lights up with numerous warning lights. I'm on the highway and I'm able to gather speed, but each time I do I hear the engine revving like crazy. We only live a few miles from the school so I am able to make it home. Once home, I turn off the car and turn it back on. The only warning lights displayed now are the red triangle and the yellow check engine light. I turn the car off, pop the hood, I check the belt and it was fine. I checked the oil and it seemed fine. I check the coolant overflow and it was empty.

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.

About 2 months ago my Touareg was rear-ended. I just got it back from the body shop and am finding little things that are not the same and I am wondering if they just need reprogramming or if these could be a bigger issue (going back to the body shop today)?
1. They replaced the entire liftgate, but the rear wiper is not working even though the washer fluid does.
2. The interior lights are on, even though all doors are shut, when the switch is set to the open door setting.
3. There is no beep when I lock my vehicle with the keyfob, but the lights blink.
4. There are no warning beeps for the parking sensors, even though the dash lights up.

My wife was driving down our street today, a two way street, narrow at best of times. On one side a monster snow pile ( 6-7ft high), the other side a very big truck coming at her, minimal passing room, like almost touching her mirrors.
The warning lights on both sides went from green to yellow and red ...beeping all the time. The Phaeton stalled. Not once or twice, but four times !!
Question : did the engine stall because of the red beeping lights on both sides sensed imminent danger ? ...... and she kept on going. She thinks so.

My 2007 Prius with 176k had the warning lights on the dash. I finally got the code read and it is the P0A80 code. The 12 volt battery seems good, it is about a year and a half old or so. That was the only code.
