Prius (2004-09) :: Red Triangle With Message Appeared
Nov 1, 2012
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.

I have a 2005 Prius with 240,000 miles. About 4 months ago the triangle warning symbol appeared. A friend and I decided to pull the big battery out of the car and find the bad cells. We did that, replace two and the car worked fine for 4 months. The triangle warning has returned. We have done several things but the triangle remains. We pulled the big battery out and checked all of the cells. We replaced one that was probably OK. The latest reading was 8 volts on cells all but one at 7.9. We cleaned all of the bus contacts. We went into the maintenance mode on the MFD and found the aux battery to be 12.6 volts and under load it dropped to 11.8 with the lights on.
The aux battery went up to 14.1 volts with the car on. The inverter cooling fluid has movement and there is a slight humming which I believe to be the inverter pump running. The inverter fluid was topped off. The MFD showed the battery bars start at about three fourths full, drop down to one bar. With the engine running the battery bars climbed to the top purple. The engine turned off and the bars continued to climb to all green. All of this occurred in about 3 minutes while the car was parked. There were codes on the MFD while in maintenance mode. I understand that these codes are for the navigation system and the audio system.

I don't understand what this message means. I drove my 2005 Prius to the Emissions Testing station (CO) and they said the OBD wasn't "READY".
The CEL goes on and off 4 times a year. It stays on for months, then goes off. The dealership said to ignore it as they couldn't locate the issue.

2004 Prius, 149,000 miles. Driving on a highway when suddenly it felt like a headwind was bearing down on me, and a minute later, the red triangle of death and all the other lights came on. Did not totally lose power. Pulled to the shoulder and while waiting for the tow truck, started and turned the car off several times.
After the first few times, the red triangle did not light up, but the check engine icon remained on. The tow truck driver had a very difficult time getting the car into neutral to pull onto the flatbed, and then when he took the car off the truck to park it at the dealership, he said it shifted "hard" into drive.
I don't have a code since I don't own a reader. What this might be? I really, really hope it's not the traction battery needing replacement. I have no training to replace single cells.

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 was on my way to work this morning when the car just stopped accelerating (or so it felt), all the dash lights came on, I pulled over to the side of the freeway (I was very lucky). Radio and a/c were still working. Powered off, powered on too soon a couple of times - the red triangle and check engine both came on again. Cooled my jets and gave it a few minutes, powered on and the red triangle was gone, but the check engine was still on. Drives perfectly, no problems w/either gas or hybrid engine.

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.

When I tried to start my 2006 Prius ,it wouldn't start and this message appears with the red triangle "there is a problem with the transmission "p" lock mechanism. Park your car on a flat surface and fully apply the parking brake.
It is at a parking lot now because I couldn't start it!

I got this message on the information display when I turned off the car after an hour of drive. I'm guessing it refers to the key getting low on battery but why only after 2 months.

I own a stock 2008 Prius.
My car didn't move for 1-2 months so I needed a boost this morning. I noticed there's the check engine light on and a red triangle.
Also, the car won't go on electric mode.

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
My 2010 Toyota Prius III has 37400 miles and I've had it since 2010 April.
My ScangaugeII didn't find any OBD2 diagnostic codes

I have a 2002 Prius that needs work. The red triangle, PS, and check engine light are all on. It has these codes:
P3100 - 175 (HV ECU internal error. Motor Inverter Current Sensor Malfunction)
p3125 - 287 (Motor Inverter Finv. Inverter Internal Short)
c1259 (HV System Regenerative Malfunction)
I suspect the inverter or even worse the MG2 has burnt windings.
BTW the "infamous" inverter pump seems to be working. I can hear it and see the fluid in the reservoir move.
I suspect it is more a symptom than a problem and will disappear when the real problem is fixed.

While driving the key not detected message appeared three different times during a 50 mile trip. The message lasted approx. 30 seconds.

The car beeped at me when I tried to lock it. Initially, I thought I forgot to turn it off. But no, it said "keys detected inside". Not so, as the key was in my pocket outside when I tried to lock it and the other key was 10 miles away at home.

I was driving my plug-in yesterday on the freeway and suddenly it alerted me the following:
Check Hybrid System
Stop the vehicle in a safe place
I pulled over to the side and tried to reset the message (push power button 3x), but message still was coming up. With my Toyota dealership not too far away, decided to bring in my car to have it checked out.
After 2 hours with their hybrid tech, they were not able to replicate the message (of course, always the case), but the tech was able to catch a P0C3E error from their diag tool. Being that they could not replicate the issue, they released my car and started to bring it back it the issue persist.

Went to start the car up this morning - foot on brake and pressed the Power button. The car went through its checks but when it finished the 'Welcome to Prius' graphic it did a continuous beeep and displayed 'Check Hybrid System' and didn't start.
I turned it off and tried again and on the third or fourth attempt the car eventually fired up, the error message was gone and there were no warning lights on the dash. The car did smell like it was running rich though.
I turned it off and called the dealers. They said if no warning lights are now on it should be ok to drive the 6 miles to see them and they'll check it on their computer. As I drove to see them the car was running OK but the fuel economy was shocking. I was getting about 40 mpg UK (30 US mpg) as a trip average.

Twice 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.

Today 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.

I've had the Dension Ice Link plus for my iPod for about a year and a half and it has worked flawlessly. Two days ago, though, the radio now reads that there is "no CD player" when I try to use it. I called Dension support and after a few other diagnostic procedures, the tech asks me to reset the radio by pulling the fuse. I wait a couple minutes with the fuse out and every single wire detached from the radio. When I reconnect, the radio is not reset. So I try again, this time for over 1/2 hour; still no reset.

Sometimes when I startup I get the message "Air Conditioner Off". This has only been happening for the past few weeks and never before. I wonder why now and not before. Have 22,600 miles.

Alright way to kick off the new year. I drove my car to and from work today... no issues. I get ready to leave to hang out with friends, turn the car on, and the message "Exhaust Workshop!" comes up. It then goes away, but the CEL stays on.
