Prius (2004-09) :: Triangle Show Up And Just Would Not Go Away
Jul 1, 2010
My 2006 has about 67,000 miles on it. The other day it began to behave in a very strange way. I had the triangle show up and it just would not go away. I checked all the fluids and they were good. I did notice that there was a new icon I had never seen before. It looked like it was an curved device with a thermometer attached. When I looked it up the suggestion was to go to Toyota right away. So I decided to drive over. As I drove I could hear the fan from the back seat coming on. It was going very fast, so I guessed that the traction battery was overheating. The car would barely drive, no power. Even when I floored it there was very little acceleration.
I got it to the dealer and they gave me a loaner because it the car was recalled due to the accelerator pedal. Later in the day I got a call saying that a couple of ECUs needed to be replaced. The next day I got a call saying the traction battery was bad and would be replaced under the long term warranty. They said I also needed an aux battery. I knew my battery was not charging up to better than 10 1/2 volts dc. They said it would cost $300 installed, so I said I would get back to them.

My Prius has started throwing the code P0A80, it all happened after I went away for work and left the car in storage for 15 days, during that time I left the OBD scanner plugged in and it drained the 12v battery, a quick jump start and it was back up and running.
While I was backing it out of the driveway the warning triangle came on and the MFD said "problem" the scanner showed the P0A80 code. I thought that was odd, but maybe related to the flat 12v battery and self discharge of the traction battery so I reset the code, it drove normally to the shops. When I restarted it and started to drive it threw the same code again.
I then installed techstream on my laptop to try and get some more in depth answers but was having trouble getting that running on Windows 8. So overnight I disconnected the 12v battery and would try again in the morning.
I got techstream working and connected it up to the car, connected the 12v and started it. While I was configuring techstream to graph the pack voltages I noticed something odd, the engine was being loaded and unloaded in 2 second cycles, and at the same time the inverter was whining as it does this. I was thinking maybe it's doing some sort of charge and measure cycle since the ECU's have lost any pack data due to the power loss of the 12v battery?
It ran like this for 20 mins or so and the engine stopped, techstream showed pretty normal cell voltages, I couldn't see any wild differences between the cells.

Our Prius has a funny quirk, one that we can live with because it only does it occasionally, but is still quite annoying when it happens. Sometimes, when the car is started, it does not turn on the electronics correctly. Most of the stuff still works, like the radio, GPS, etc. But when it does this, the only light that shows on the console is the check engine light (which is on for some coolant sensor that we don't need to fix right now) is the only thing lit. Nothing else, including the gas gauge and odo and MPH gauge, lights up. On the Consumption screen, it also does not register miles driven, avg MPG, and does not track anything. The energy screen works fine, although it does not show current MPG, as if it doesn't really know the car's all the way on.
Only totally random stuff makes it stop, such as driving a short distance, turning the lights on, entering maintenance mode, or restarting it. (This problem usually prevents the car from shutting down, also, which can be quite annoying.) Fortunately this doesn't seem to affect the car negatively in any was other than not knowing how fast you're going. Dealer didn't pick anything out reading codes, and it doesn't do it all the time (although short starts, such as turning on to roll down windows, usually seem to cause it.)

I have a 2006 with 154,000 miles on it. I usually have my oil changed at Valvoline, but the last time the tech said there was no oil in my engine. He did drain oil out of it and filled with 3 1/2 quarts of oil. It did not show on the dipstick. This last change I did myself and used 3 1/2 quarts of oil, ran it around the block, waited about 5 minutes checked it and it still does not show on the dipstick.
Could I have gotten the wrong dipstick at some point? This one fits and seals good. I now do not want to run very long not knowing what my level is. Can measure the dipstick length? To compare with what I have.

I've been trying to trouble shoot this for quite some time now and I still can't figure out why the passenger airbag will show "off" and won't turn "on". This is on a 2006 Package 3. I read a properly functioning passenger airbag light would not indicate "off or on" unless someone is sitting on the passenger seat. Mine will show "off" regardless if there is a passenger or not?
I ran a diagnostic with the MiniVci and everything checked out, no error codes, the Airbag ECU is detecting everything as normal. I did a sensitivity check and the weights were within specs. I don't know where else to look.

I have recently noticed that the ODO meter of the car does not work i.e. it is stuck at the reading (57735 km) it was on when I got the car and does not record/show the increase in mileage. the trip A and B are working perfectly fine. I took the car to the local Toyota dealer but he has no clue what is wrong with it, the guy there suggested that ECU is working fine but the ODO meter is damaged and needs replacement.
I am not sure what the guy at the dealership suggested is correct because what i think is that if ODO gets damaged then the whole speedo meter should mal function.

I have a 2004 Prius, the Red triangle came on intermittently and went off so I changed the 12V battery last night, after changing it the red warning light went off and everything seemed okay. Today while driving, the warning light came back on. I checked the battery voltage via diagnostic mode on the cars computer and the specs are what they should be. I noticed the following error codes in the computer:
01-D5, Sub-code: 190-30-8
01-DC, Sub-code: 190-B7-8
01-DC, Sub-code: 1C6-4D-F
Not sure if these are what is causing the problem.

After driving for 2 or 3 miles my car turns on this red triangle and says "problem" on the GPS. All the threads i have found this is accompanied by a check engine light but mine does not. On the gps there is also a symbol that i looked up in the manual, it says to take the car to a dealer. is there any way to know exactly what this triangle means? There is not CEL tripped, tried 4 code reader and nothing.

My 2007 proud of 180k miles which hasn't had any issues up until now just randomly gave me this error, where the red triangle of death, vsc, and tire pressure ((!)) Sign came on. It drives fine and there is no check engine light.

The red triangle warning light on our 2004 came on and went away again It has 100k miles If I take it to the dealer can they pull some codes and figure out why it turned on We have to drive the car to 600 miles for the upcoming weekend and I don't want to be stranded on the side of the road The car has 103,000 miles We just replaced the 12v battery so I know that is OK
I also saw the following things to check. Is there anything else we should check?
1 - Are any warning lights on besides the red triangle? For example, the red BRAKE light, the amber ABS and VSC lights, or the amber circular icon?
2 - Did you check the brake fluid level? If low, buy a new container of DOT3 brake fluid and replenish as needed This fluid will dissolve paint, so do not spill it
3 - While you are at it, check the radiator and inverter coolant levels by looking at the translucent reservoirs behind the radiator and next to the inverter If low, fill with Toyota Super Long Life Coolant

Recently while pulling into the gas station the brake, Triangle !, ABS and VSC lights came on. The dealer reset the error and said my ECU needs replacement at a cost of $1843. The Prius is a 2005 with 147000 miles. No problems since the reset so I am hopefull. I don't recall reading about a lot of others having to have expensive ECU replacements so I wonder how many have had similar problems and replaced their ECU.

I went to the dealership today with my '05 displaying a master light ( big red triangle) and "problem " posted on the screen with the green "hybrid system problem" box displaying.
The Prius guy had the car plugged into the computer for over 3 hours. It spat out a page and a half of codes, and then after a time distilled the codes to 4 things: a bad hybrid fan motor, the relay, a blower motor controller, and a bad aux battery. The problem is I replaced the aux battery a year ago. So it makes me doubt the entire diagnosis.

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.

2008 Prius with 284,000 miles-never had problem. Now, started car, no power steering (red triangle). Ordered new power steering control from ebay, went out of town for 10 days. Return, car is DEAD! Trickle charge via fuse block, get car started finally, still no P/S, but it shows charge then shuts engine off. Start and it does same thing.

The battery in the back looks like it got smashed a little. Do you think this is the cause of the lights? It was a small suv so it missed the bumper and went straight into the battery area. Trunk wont latch anymore the it got pushed in.
Is there an electronic box back there that could have caused the lights to come on?

I just bought a 2006 Prius about a month ago (57K). I love the car and have been educating myself on all things Prius, This car has also made me change my driving style quite a bit. I am getting around 50 MPG (combined) and very happy about it.
I have been using some of the hypermiling techniques to get the mileage, one of the things I do is to put the car in Neutral (to emulate the Glide portion of the Pulse and Glide) especially when coming down a gradient. I was bit concerned about using the Neutral gear and called Toyota Corporation to get a clarification, The answer I got from Toyota was - there is no technical issue, however they do not recommend this be done for safety reasons.

I purchased a 2009 Prius last year in the US and then got stationed in the UK. I had my car shipped Aug/Sept 2013 to the UK. Up until now the car has run great with no problems. Three weeks ago a red triangle with the message "there is a problem with the transmission "p" lock mechanism. Park your car on a flat surface and fully apply the parking break" appeared.
A week later the car wouldn't start. After reading several forums and posts I checked the battery and it was indeed low. It looked like the original battery and was reading 9.3V. I had the car jumped, drove to the local Toyota dealership, and bought a new battery. After installing the new battery the car ran fine with no issues.
Five days ago (Friday) the car wouldn't start in the morning, but all of the lights worked. Then about 3 hours later the car stared and ran fine all day.

The other day we had a little rain, drove the car parked it left the wipers in the on position. Went to start the car again for another jaunt, and pressed the start button and brake pedal, the wipers came on very slow and the red triangle on the mfd came on. So I turned off the car and tried to start again, every thing was fine. So I am thinking my 5 yr aux battery is failing . Would I be correct in thinking that?

Basically I have two problems which will be looked at by Toyota on Friday. But I need to arm myself with ammunition in case I have a debate with the service/repair guy.
Firstly my gen 2 decided not to start for about 10 minutes and gave me the red triangle with an exclamation mark before everything went back to normal again. The car starts every time now but the triangle appears briefly at the start which I don't think was there before. Could this be the 12V battery?
Another thing is grinding noise on full lock to both left and right. What could this be?
