Prius (2010-12) :: Check Hybrid System / Yellow Triangle With Exclamation Mark Came On
Aug 31, 2014
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.

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?

My wife was driving our 2009 prius this morning. she said the red triangle, this other yellow circled, light with an ! came on plus in the display window the car icon with the ! came on. Manual states that this is a hybrid system failure.
On very cold mornings the car smells very hot for a period of time. She said this happened again.
I tried to do a reset (turning it off and on atleast 4 times) did not work. So I had it towed to a dealer tonight and I started it again and this time very hot smelling and a whole lot more lights were on, ( brakes lights, almost all of the lights I would say.)

I had a triangle with an exclamation point (not red), a check hybrid system message, and an airbag indicator come on in my car in February. I thought the triangle with the exclamation point was originally yellow but my eyes could be playing tricks on me. It now appears orange.
In February, the dealership told me that some kind of rodent apparently chewed through wiring containing the airbag tether and hybrid system wires. I was told this is a 3K+ repair and was advised to make a claim against my insurance. I am working away from home until June, so I was going to wait until I go home to have my preferred dealership handle the repairs.
Does driving solely on the gas system harm the Prius? Does the car have both yellow and orange triangles with exclamation point warning indicators? By driving the car in the condition it is in, am I harming it and is the possible change in color of the indicator a sign of a worsening problem?

I've got a 2009 Prius with 67k miles on it. The car has a salvage title, but has given me over 20k+ worry free miles. The past few days the car has been acting a bit odd (i'm not sure if these are related or not but I figured I'd just throw it out there as well).... The right front headlight has been on the fritz as well as the wireless door opener has been working sparsely (sometime it wont lock, sometimes it will). I just ran the test to make sure teh 12V battery was okay, and all of the voltages came back in the "normal" range.

This morning I started my 2008 Prius (approx. 31k miles) and found the big red triangle with an exclamation mark and check engine light turned on.
I drove my car <1 mile to a smog check station where they ran a diagnostic on it and came back with the P0A9C code.
A quick internet search turns up that this is "HYBRID BATTERY TEMPERATURE SENSOR "A" RANGE/PERFORMANCE."

Today i had my front discs and pads changed on my 07 prius and after putting it all back correctly I went to drive the car and my abs , vsc and both exclamation marks where lit up , I've read that this is common and a quick reset on a diagnostic machine should shift them ? Is this correct ?

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

"Yellow exclamation point in brackets is on. Squiggly line below mark. What does this mean?" I did some research and everyone says tire pressure, yet all my tires are the right pressure... SO could it mean something else? I would look at the owners manual, but unfortunately don't have it...

I was driving on the freeway in houston yesterday and it was about 30 degrees. The low temperature light was on... Does it make a difference when it is cold? Why would there be a light to tell u that it is cold outside?
Anyways as I was driving on the freeway the red triangle with an exclamation mark came on and disappeared. Then a minute later it went on again and on the navi screen shows high coolant temperature symbol on it. But then it would turn off right away too so is this normal because I was kind of slowing down on the freeway and the book did say something but I don't think it was an excessive speed or anything.

So at about 147k miles, triangle comes on. It's the icon on the right with the car and exclam! mark through it. Turned off radio. listened to car and I could swear that it was running differently, but it might be in my head (I was kind of freaking). Drove to my Prius guy in the I.E. (20 miles) car seemed to act OK. Was using elec engine when needed and gas engine was fine. Was a bit shocked by how good the car was running but I was sure something sinister was happening and at any minute the car would melt. After 1.5 hours and a 20 mile test drive.

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 have a 2007 Toyota prius base model, it has 49,845 miles. Today i got in, pressed the bake, pressed the on button, and the Red Triangle appeared with yellow exclamation point in a circle, and on the lcd monitor it shows that there is a problem and a little icon of a car with an exclamation point on it.
The car drives and runs normal, fuel mileage seems to be the same, everything looks normal except the lights. One thing I tried to do: I took off the battery clamp and i put it back on, the warning lights were gone, but as soon as the engine kicked in the same warning lights came on.

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.

I have a 2005 Prius with around 115,000 miles.
I have the following warning lights on:
1) Check Engine
2) Yellow Indicator, looks like exclamation point inside a circle inside parenthesis.
3) Red Multi-information display (exclamation point inside a triangle)
4) Hybrid System Warning Light on display screen, looks like exclamation point through a car
The engine cranks up just fine and drives forward and backward in the driveway fine. Battery level indicator is blue (see image). I checked for turbulence in the inverter reservoir with the engine off and fluid was flowing.
I checked the 12V battery (using the car's measurements by holding Display and turning lights on and off 3 times) and its value was 12.1 volts without engine and A/C on and 11.8 volts with them on.
The fan in the back right passenger seat is always on now though (I don't remember ever hearing this fan noise before), regardless of engine on or not, even though it's only about 80 degrees outside and it's been sitting idle all day and all last night. It comes on pretty much immediately when the power button is pushed.

My boss has an 08 Tiguan and he got an error light on his dash coming to work today. It's yellow with an exclamation mark in the centre. On both side's there's a solid line and on the bottom it's got a "squiggly" line.
What it might be or if this is something known about them? He states there's no performance loss or anything acting up at all. Short of bringing it to a dealer which will be closed by the time we're both off work I thought I would start here.
