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?
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.

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.
My Prius would not start at all ( getting off from work last night. ) All kinds of flashing/blinking lights on the dashboard. Even the door locks won't work. I'll be calling my dealer first thing this morning.
View 3 RepliesMy 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.
I currently have a 2008 Touring Package 6 with 180k and I am getting weird problems. I am getting the triangle of death, VSC, and yellow ! light. There is no check engine light. On the LCD I am getting the red battery + - icon as well as the car hybrid icon. I scanned it and I am getting a hybrid code P0A09 . All of the maintenance have been kept up and all fluids are perfect. No weird noises and the car is doing 53 mpg. It switches between gas and electric with no problems at all. Symptoms were yesterday with the lights. I cleared the codes and they would come back instantly. Today, I did the same thing and now everything is perfect. I am attaching the pictures of my dashboard lights that were on and the codes I was able to obtain in diagnostic mode.
View 11 RepliesTwice 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.
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 RepliesQuick 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 RepliesI tried installing a backup camera today. big mistake. When I start the car the yellow triangle shows up. and warning says check hybrid system. I try and put the car in reverse and I hear a snap, it slips to neutral and a warning appears that says put into P position. The only wire I tapped into was the red reverse light camera. I even tried undoing the install and I get the same messages.
View 18 RepliesToday 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.
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.
I got "check Hybrid System" error with all sensors are yellow on the dashboard of my 2011 Prius with 80k odometer reading. Currently no Hybrid system, only petrol engine works.
View 2 RepliesWhat to check and do on my 07 Gen 2 Prius odo 109450 miles
My dashboard lights have the red triangle master hybrid /vsc and brake all on and I can still drive the vehicle.
I have been rechecking my repair work however after replacing the following parts
12v battery
inverter pump
coolant
traction battery
I am unsure how to troubleshoot my issue.
I have had the Prius for a little over 2 years now. Bought used and currently close to 150K miles on it and have put on about 25K miles a year.
This evening on way back home, when I turned on the Prius, I got the Red Triangle along with a bunch of other lights ON the dashboard.
Pressing the power button and everything would take much longer than usual - the lights(on the clock) was dim, the windows moved up and down rather slowly.
Eventually, i had to jump start and carefully drive home. Afraid it would stop somewhere at stop signs or long red lights, i constantly kept pumping the accelerator(not sure if that was good). Seems like need to replace the 12V battery.
I have done some maintenance on a recently purchased 2004 Prius. Namely, replaced the inverter cooling pump, the right front wheel bearing and rear brake pads.
At a certain point, the brake, (!), VSC and ABS lights came on on the dashboard.
My wife is driving this car so I did not get the exact moment when the lights came on after my repair jobs.
I then replaced the 12V battery with a new one and reset the lights with the PIN 4-13 jumper on the OBDII connector. I did retrieved the error codes of each light and I googled them without any result and I now lost the paper where I had then written on
I have a 2010 Prius Hybrid and lately, on an intermittent basis, I will press the brake pedal and push the start button and the dashboard lights up as normal but when I go to put it in gear nothing happens. The last time it happened the fan was running and I couldn't turn it off. It's like the car is all set to go but all the interior controls don't function. I then shut it off and restart it and everything works.
View 1 RepliesI have a 2001 Prius with 204K miles. On cold mornings when I start the car first time, within a minute it shuts down with red triangle flashing. After resetting it, car works fine all day without any problem.
View 8 RepliesThis 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 RepliesDriving 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.
View 8 RepliesI 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.
