Prius (2004-09) :: Red Triangle Sometimes Shows When Starting Car
Oct 29, 2012
I have a 2008 Prius. I noticed that a large red triangle displayed briefly on the left when I started my car the other day. I know all the other smaller icons light up briefly but I don't remember the large red triangle lighting up. It and all the other icons go off after a second or two. Then the next time I started the car there was no red triangle. Then maybe the 3rd time I started the car, the large red triangle did again appear briefly. I took my car to my Toyota dealership but the tech said that is normal and means a door must be open, but that cannot be correct. I make sure all doors are closed and the "Open door" icon is not showing. I have already been through the water coolant inverter pump disaster so I admit I am a little paranoid about any funny things showing on my dash.

I have a 2007 Prius and the red triangle showed up. It has less than 50,000 miles. I noticed that almost right after I start it up the hybrid battery fan kicks on. This leads me to believe that maybe one or more cells in the hybrid battery are overheating due to charging problems. Is there a way I can check this out without going to the dealer?

I 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.

I use a scangauge to monitor the traction battery in my 2001 prius. Today when I started the car to come home, the alarm triangle came on, but the scangauge shows no codes found. The car ran fine and got me home, but what the alarm is about.

2006 Prius with 130k miles. I'm thinking that my HV battery has slowly deteriorated to the point where it's causing drivability issues, and now needs to be replaced.
The main symptoms I'm experiencing are rapid charge/discharge according to the MFD and significant loss of power once the battery has discharged to one bar. I realize the latter is "normal," but the problem is that I'm seeing one bar frequently now. Hill climbs that my car used to do with no problem and would drain the SOC to 2-3 bars now cause the battery to drain to 1 bar about half-way up and then loss of speed from 65 mph to 45 mph by the time I reach the top. Descending hills, it's not unusual to see the SOC go from 2 bars to 7-8 bars within 30 seconds or so.
I'm not seeing any error lights, and my (cheap) code reader does not report any logged DTCs.
This seems to be a slow degradation of battery performance, rather than an outright failure. I first noticed that the battery would charge/discharge a little quicker than it had been at about 90k miles. At 99k (before the warranty ended) I took it into the dealer and they tested the HV battery. Block voltages ranged from 16.59 to 16.68 V and resistances ranged from 0.025 to 0.026 ohms. Based on this, they said that the battery was fine, and sent me on my way. Since then, the problem has just gotten worse and worse, though.

I saw a really weird thing happen about half an hour ago. Hadn't driven that car today until I made a quick trip a bit ago to pick something up.
As I was coming back from the store I noticed the display was showing extremely low numbers with barely any speed/coasting. After I got up to ~30mph and started slowing down, I noticed the display was actually showing the mpg decrease as I applied the brake.

Been driving for 3 days now for a total of about 100 miles from a full tank averaging 50 miles per gallon. I noticed the gauge still shows FULL. Not even a bar below or something. Is there anything wrong with my gauge?

My 2001 Buick Lasebre is not starting properly. I have to pump the gas several times before it will start; then when it is started at low speeds or idle it wants to stall. As long as I can some how keep pushing the gas peddle it wont stall. On the other hand when I am driving at higher speeds, anything above 40 or so it runs perfect. The check engine light was on and shows EGR valve stuck open. I have replaced the Mass airflow sensor, fuel filter, and the EGR valve. I had the code cleared and a short while later my check engine light came back on with the exact same reading. I bought this car only a week ago and was not expecting to have to fix a car I just bought and ran fine while test driving it. I have read may different forum that say that it could be anything from my fuel pump to vacuum hoses, to some other sensor.

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.

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.

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.
