Prius (2010-12) :: Yellow Triangle Flashing / Dashboard Lights Up But Won't Start
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?
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?

I am going to remove LED headlights & do a full HID retro.
Only problem is that the car has a system check & throws a flashing yellow triangle. How to trick the system?
There are 6 wires on the LED headlight harness.
Prius (2010-12) :: Yellow Warning Light Flash For A Few Seconds And Then Turn Solid
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.

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.
Prius (2004-09) :: 2005 - Getting Red Triangle And Warning Yellow Symbols?
My 2005 Prius has about 141000 miles on it. The red triangle exclamation point comes on the dash and a yellow exclamation comes on the LCD 1st and then a 2nd yellow symbol comes on the LCD. The problem happens once or twice a day. It seems to start, run, and drive just fine. I do restore antique tractors and I am pretty good with computers and I have some pretty good mechanical know how. Attached are pictures of the lights.
View 1 RepliesPrius (2010-12) :: Yellow Triangle Alarm With Message Key Battery Low
Twice this week I have received the Yellow Triangle alarm with the message Key Battery Low. This is the first time I have seen this alarm since I bought the car in August 2009.
I changed the battery the first time after 3 years based on recommendations from the forum. This time the batteries lasted just over 2 years.
I tested the batteries on both Key Fobs and they were both in the 2.9V range. The new batteries tested at 3.3V which is their rating. So ~2.9V must be the low alarm setpoint.
Prius (2010-12) :: Yellow Triangle Light Illuminated On Dash When Hit The Brakes
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...
View 16 RepliesPrius (2010-12) :: Yellow Triangle With Message - Low Traction Battery Shift Into P Position
Today after running several errands, I stopped by the local CarWash to rinse the car. Same as always, parking brake off, shift into neutral and away we go. Half way threw she starts beeping, I see the yellow triangle and to the right a boxed message "LOW TRACTION BATTERY SHIFT INTO P POSITION". There was a sudden rush of anxiety because I could not shift while being conveyor-ed threw the wash. As soon as I was pushed out and the light turned green, I shifted into drive to exit. The warning and box cleared instantly.
I pulled into parking, shifted into P, and noticed the battery indicator had only 1 bar. Did a quick walk around of the car and got back on the road thinking, head directly the Dealership. Before I got to the freeway I was back up 4 bars and climbing. Continued on the freeway and within 2 exits all looked normal. As it is Saturday and the Dealership was 1 hour from closing, I proceeded home. Later we went to dinner and an event, then came home. All is still normal. Owners Manual only states to follow the command on page 515.
I know this is a long story and was intentional to starve off multiple questions. The only thing I can think is that the air conditioner, radio and headlights were on prior to, while waiting my turn for wash (park-roll-park-roll...) and up to the point of the warning (tuned off all at that point) while in the tunnel. However this is normal for me. Will monitor the battery indicator more closely for a while. I'm sure this event latched in a computer somewhere, so will run by the Dealer if anything else acts up again. A/C and radio and lights are turned off now while in "neutral", for whatever reason. The car is a 2010 II and only 27600 miles. Was not a pleasant feeling.
Prius (2010-12) :: Check Hybrid System / Yellow Triangle With Exclamation Mark Came On
Yesterday, started it up, began backing down the driveway, controlling speed with a little pressure on the brake. There was momentary weirdness, like the brakes had sort-of let go, then gripped again. And then got the warning "CHECK HYBRID SYSTEM" and a yellow triangle (inverted?) with exclamation mark.
I tried maybe 3 restarts, but the warning persisted. Phoned the dealership, booked-up Saturday, but they said they'd (commendably) squeeze it in. So we brought it in, when they eventually got to it they read the codes, cleared them, test drive, said it appeared the computer(s) "lost contact" momentarily, and it seemed ok.
I got in and started driving home, down the back lane first. Car started making a VERY strange buzzing sound, coming from under the hood. By the end of the lane I decided I better circle back to the dealership, pulled in at the curb in front, left it running and raised the hood, the hood support rod was loose, laying over the engine, doing a dance.

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.
View 4 RepliesPrius (Gen 2) :: Won't Turn Off - Master Warning Triangle / Some Electrical Humming
This is the second time this has happened in the past few weeks. Each time at first start in the morning. Each time temperatures had been in the mid-20's (F) overnight.
Push start button and it seems as if electrical systems "sort of" come on -- there is a low hum of some sort, but the little light in the power button stays a dull orange and the Master Warning triangle as well as several other lights on the dashboard come on (Traction/VSI and some more, I don't remember).
Gas engine def. NOT running. I then hit power to turn off the car and nothing happens. Still "running" although really not, other than some electrical humming. Can't shift into anything (Reverse, Drive, etal).
Prius (2010-12) :: Orange Warning Triangle?
I am lucky my SO (more on that in FHOP) had the diagnostic tool to see why my Prius woke up with a headache as I was starting my day. Displaying the orange triangle, telling me to park and then telling me to shift to park... Yet I parked her in the garage the night before. I should have had a pen at the ready as I did not get the three codes that came up (they are stored on my SO's work computer now). Two were about some miscommunication - one having to do with navigation; the third was a malfunction with the USB port... I have had a few issues with connecting my iPad to the USB port.
I am getting close to 10K as well. Very fortunate to have a Prius doc in my world!
Prius (2004-09) :: AC Stop Cooling / Little Triangle Warning Turn On And Vehicle No More Moves
Need to solve the problem of my Toyota Prius car in 2008. The car is cold while working well for a maximum time of 1 hour, the first symptom is to stop the air conditioner to cool, then turn on the light triangle warning, after driving a little longer for the vehicle and no more moves. If you wait until the vehicle returns to work for a few minutes to cool, then everything fails again with the same symptoms. And you change the battery 12 Volt, and you change the water pump hybrid system and I can not solve!
View 3 RepliesPrius (Gen 2) :: Red Triangle And Yellow Exclamation Next To It Just Lit Up
Driving my 2008 with 189,000 miles on the congested "freeway" the ominous red triangle and the yellow exclamation next to it just lit up. A quick scan of the OBD showed no error codes and good auxiliary battery, engine coolant Temps etc. And good gas mileage, engine vacuum. I had replaced the spark plugs with new iridium two months ago. When I stopped and checked the hybrid converter had good levels and turbulent flow. The oil had been changed a week ago and checked again at lunchtime. Now only the red triangle shows.

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.

My 2010 Prius (130k miles) has recently started beeping on curves, turns and braking on occasion. The red triangle also comes on. There is no problem otherwise. It is a bit annoying. What is the cause of this? Could I have the beep turned off?
