Prius (2004-09) :: Red Triangle And Yellow Exclamation Point In A Circle
Feb 12, 2012
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.

My Prius has about 145K miles on it and use it on a daily 130 mi round trip commute. Recently, a I got a Red Triangle w/ Exclamation Point and the displayed showed "Problem". I took the car to the dealership and they stated the problem was caused from a low oil level. The dealership changed the oil and I was good to go. 3k miles later, I got the same error and noticed my oil level was low once again. It seems that my Prius is burning oil at rate of 1 quart per 2500 miles driven. What can be causing this? Are there any remedies I can try before changing out the piston rings?

I am getting the red triangle and the little car with exclimation point on the MFD. Interestingly all of the amber lights are on and the brake light is on BUT the parking brake is not set.
Here is what happened --my hybrid battery died a few weeks ago so I ordered a replacement through Summit Racing (Dorman Battery). The car started and drove but I had to rest codes to keep it alive (just to get it home). Last moved it 3 weeks ago and removed the old battery.
So long story short -- while I was waiting for the new battery I repaired some other issues -- BTW I am not new to this, I have the tools and have done these repairs on conventional cars many times.
1. Leaking axle seals -- replaced L and R seals
2. replaced L and R half axles (drivers side was rough so replaced both)
3. Found drivers side wheel bearing to be rough so replaced L and R hubs
4. Replaced L and R struts and strut mounts.
5. Drained and refilled trans axle with Toyota W (TF) 4 qts
6. Installed new 12v battery (currently producing 13.4v)
7. Replaced rear struts.
8. Replaced L and R front rotors and shoes -- they were off anyway so why not. No loss of fluid!
9. Removed and cleaned most interior parts -- door panels, seats etc...
Installed new HV battery and fired her up to the usual wheezing, whining and clicking sounds. But NO engine -- just the triangle -- problem statement and and the other above issues.
Checked the following -- inverter pump is circulating nicely, though maybe battery electronics -- so I placed the old battery back in (it was started with the old one 3 weeks ago) -- nope same issue so not those electronics. Traced all wires, plugs and connectors related to hybrid system -- all seem to be in place.

The triangle comes on momentary for the past week. It first occurred when I turned right at 20 mph. The next time was during a sweeping left turn. Off and on with turns left and right. the last few times it was longer in different situations and I could read the LCD display where is said "PROBLEM".
The local dealer said check brake fluid and open and close all doors. Since it is more frequent I called my mechanic and he thinks it could be door sensors that have built up junk. The dealership does not think it is a safety issue and without any lights on their analyzer could not pull any codes.

"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 have the red triangle with the exclamation point in it. What it can be? I have a 2006 Prius. It still seems to drive ok. I have parked it though and have an apt Monday morning at Toyota. (They didn't have a Prius tech in today) When I first noticed the light it would come on and go away. Now it's staying on.

I have a 2008 Prius, with SKS and Nav, and 103,000 miles on the odometer. I bought it from the original owner in 2010. So far it has been trouble free, with just oil changes and scheduled maintenance.
When I turn power on, I get a red triangle with exclamation point. Also a row of yellow indicator lights. Also along the top of the LCD display there is a red car shape with an exclamation point on it.
I followed the procedure for checking the voltage of the 12v battery using the diagnostic screens, using the procedure at weird-stuff-happening-mpgs-dropping-test-the-battery.73400/and I got 11.8 volts.
Since it seemed likely that my problem is related to the (original OEM) 12v battery, which is now 6 years old, I took my handy jump-start battery thing (see photo below) and attached its red alligator clip to the positive post under the hood, and the black clip to the frame. I hoped that would allow me to start the car, but it did not start. The error lights on the dash were unchanged.
Question 1. Does the fact that the symptoms remain the same after I have connected my jump-start battery mean that the problem I'm having is NOT my 12v battery?
I then hooked up my cheap OBDII code scanner (see photo below) and checked for codes. It found none.
Question 2. Does the OBDII scanner not finding any codes have any importance? When people write about having their car towed to the dealer and having error codes read there, does that refer to OBDII codes, or are they referring to some other type of codes that can only be read by a dealer?
While I was in the diagnostic screens, I found three screens of error codes. The screens are called DSP-AMP, EMV, and NAVI. See 3 photos below.
Question 3. Do these error codes have significance?

I have a 2009 Prius Touring with about 55,000 miles on it. Had it regularly serviced last Thursday at the Toyota dealer/service center, and they said it needed to have the coolant flow control valve replaced due to sticking - so I agreed and they did it under warranty.
On Friday afternoon, I was driving out to the desert and about 50 miles into my trip, the red triangle with exclamation point symbol appeared on my dash, and the word "Problem" beeped on my screen. Then it went off, and then back on a few minutes later. Then it happened again and the high coolant temperature warning light came on the screen...and then went away. I turned off the A/C and opened the hood to check for steam or heat, but there was nothing. Since I was far from my destination, I called the closest Toyota service center and promptly drove there, but the light was off when I arrived. They said they checked everything out and ran the codes, but nothing came up.
When driving home on Sunday, the car did the same thing - Problem Triangle and High Coolant Temperature warning light on and off for varying amounts of time and with no correlation to how fast I was driving or how hard the engine was working. I left the A/C off the entire time.
Today, the car did the same thing after driving for about 10 miles. I brought it back to my regular service center, they ran codes and checked everything out...but they cannot find anything. They said they can't determine anything with the light off, but it doesn't stay on consistently so it's nearly impossible to bring it in with the light on.

I've had this happen twice: Foot on Brake, press start, car powers up. RED Triangle with exclamation point on dash. Message on MFD screen says something like "Transmission not properly engaged, move vehicle to level area and press Park"
I can't move it anywhere because nothing but the electrical system works. I can't even turn it back off.
Toyota tells me have it towed. They send "their guy", who is also the area AAA guy. Tow truck driver says he can't tow it because it won't go into neutral. So he jumps it...car shuts off when power is pushed. Push power again. Car starts fine.
Drive to Toyota. They keep it all day, do all kinds of diagnostic tests, tell me there's nothing wrong. I ask if it's the battery, they say it tests fine, but they'll replace it if I want (of course they don't keep it in stock and have to order it).
The car did the same thing this morning, but I was able to turn it off & restart. (That makes it #3)

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.

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.)

My 2008 Prius has approximately 116,000 miles on it, about 8,000 miles ago, I put on a Mobil 1 Extended Performance filter and 5W 30 Mobil 1 Extended Performance Full Synthetic Oil. Over the past week, My "Exclamation Point Triangle Light" (Not sure what it's called) has flashed a couple of times when coming to a sudden stop and the car would emit a "beep".
My first assumption was low brake fluid, but today when I got home and checked the fluids, I found the oil to be approximately 1.5 quarts low... I have not noticed any leaks under the car (I park in the same spot at work daily), and haven't noticed any smoke coming from the rear...
What the problem might be? Is it possible I might have damaged the engine by driving on such low oil for an unknown period of time (guessing a couple of weeks or so)? I used to religiously check the oil in all my vehicles, but have gotten out of the habit on later model vehicles...

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.

My wife and I own a 2006 Toyota Prius that we bought used 2 years ago. a couple of days ago, the master warning light (red triangle exclamation point) and check engine light came on. I took it into the dealer and of course, our hybrid battery was dead - battery and a new ECU required.
Our car is at 99,000 and 32 days out of warranty. Went down the road to atlanta hybrid repair. they were incredibly nice, and said that my computer was fine, but the battery would need to be replaced.

I am getting a 3006,3011,3015 code from my 2001 prius. The car only has 56k miles on it but sat for 8 months without starting or unplugging the batteries. I am wondering if i need to replace bank 1 and 5 on the battery to get the engine light off? The car runs fine and drives great but engine light is on and the triangle exclamation point is on but that's it for lights. What do i need to do? Replace battery altogether? recharge the effected banks?

I just acquired our second Prius, a beautiful 2002 (Gen1 in the USA) with 90k miles. On the dash, I get the red triangle of death with the exclamation point inside it. On the computer info screen, I have an icon of a car with an exclamation point in it and it reads "problem". I have connected the OBDII reader to it and it does not have any codes. Nothing in the history, or in the current or pending. The car has full power and runs fine, but has the stupid RTOD.

My wife's Prius now has the check engine light, the orange triangle, and the car with the exclamation point lit up. It only has 96,000 miles and hasn't been in a wreck that we know of. I've read that it has to do with the HV ECU, but I don't know much more about it. Is there any chance it's just a loose cable or something simple? It doesn't seem like her car should already be having so many extensive problems all at once. We haven't had any in the past, except the car with the exclamation point came on for a few days and then went away on its own.
Codes: P1636, P3106, P3002, P3006. It's a 2002 Prius

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 have an 05 mk4 GLI. Driving to work today my car started to sputter a bit and the yellow caution triangle with the arrow circle around it turned on. It wouldn't let me accelerate and when it would change gears they would slam into place. Right after that my check engine light came on. is that triangle traction control?? Ive read many different threads but couldn't really find anything.
