Prius (2004-09) :: 2005 - Red Caution Symbol On The Dash
Jan 24, 2011
I woke up this morning and started up my 2005 prius to warm up. I live in New England and it freezing out today. About 15 min or so later I go back out to the car that only had the heat on and I find a large red caution symbol on the dash. I check to see if the e brake is on and thats when I look up and see it, the main battery symbol on the gps screen. I looked at my battery and only one small bar was lit up. I then noticed that the engine sounded like it was giving all it had. I turned off the car and went inside to call Toyota. I am waiting to hear back from someone in service to tell me if I can drive it. I have under 90k and it is due for an oil change maybe it's over by 100 miles. I did get the recall for the water pump and was planning to have it done with the oil change.

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 have a 2004 Prius with self-leveling headlights. I have no problems seeing at night but i have a red triangle on the dash and the headlight symbol on the monitor. I was able to aim the lights level when the self-leveling sensor broke. but is there a way to disable the sensor so i don't have any of those symbols on the dash or monitor it just is pain to look at the the sensor cost to much and it doesn't have any affect on driving during the day or night.

Really need diagnosing an on going electrical problem I'm having. It's on a 05 X 4x4 V10 with almost 113k miles.
Background : Last summer took a road trip and alternator went out and was replaced. On that trip started seeing problems with my cruise control, when the headlights(HID's) turn on they dim the dash, and hi's cause the speedometer and other gauges to quickly flux and then go back to proper readings.
Everything was "alright" in the sense that the only problems were those stated above. Well tuesday night on my way home from school, I was driving on the surface streets, stopped at a light.....then all of a sudden the battery symbol on the dash flashed and no more than a second later, the car stopped. All dash lights/radio (double din) still on and headlights still on, but couldn't start the X at all.
Was able to wait a bit and once my parents got there it did start and I was able to pull off to the side and diagnose it a little better, dad looked at it and at the moment couldn't really tell what would be wrong. I had him drive it home for me though. It's been starting fine again but I have NO CLUE as to what to look for and really would like to find out what's happening.

I got to work this morning and had about 3.5 miles left with the EV. Tried to go home and nothing works. I could not open the door. I thought it was my remote battery so I Changed the battery and still nothing works. I get the Orange caution light on the dash and a clicking sound from the engine area . No lights come on. Nothing.

I searched and found a few posts with similar issues, but could not find any solutions, so I'm checking again.

I've got a 2006 Prius with GPS navigation. Is there a way to get rid of the caution warning on gets every time one starts the car? I have to press "Agree" each time and am looking for a setting to get rid of the warning. The warning reads:
CAUTION
Drive safely and obey traffic rules.
Watching this screen while vehicle is in motion can lead to a serious accident.
Make all selections only while stopped.
Some map data may be incorrect.
Read safety instructions in Navigation Manual.

Well, just replaced my HV battery, hooked everything up (I think) and tried to start it. ALL the caution lights came on and stayed on. This is the code that showed up on the reader. P0AE0. The battery was refurbished and I changed over my Computer module and the contact posts. Everything is tight, and I compared my pre-takedown pics to the post-repair work and it all looks correct.

So our '06 Prius has been very, very reliable, and we have a bit over 105K miles on it now. But we have a problem that the dealer hasn't been able to confirm, much less fix.
Probably three months ago now I began to notice that, from time to time, when I started the Prius, the master caution light (red triangle) would come on for 2-3 seconds. At no point did it stay on, and at no point did the Prius fail to start. So, it was an intermittent caution light of brief duration.
Then we had a bad storm coming (Sandy) and although it wasn't nearly as bad here (N. VA) as it could have been, I put the Prius in the garage, and it sat there for three days. When I went out to start it, the 12 volt battery was dead.
Fortunately I always back into the garage, and so jump starting the Prius - although it was my first time doing so - was no problem, and I got it to the dealer that morning. They tested the battery, and it was fine. They checked the codes, and all was well. It was as if the battery had never died. AND we stopped seeing the master caution light ... until two days ago, when my wife said that she saw the light a couple of times when she was out running errands.
Is it possible to have a problem with the 12 volt battery and/or electrical system that doesn't show up in the codes? And am I wrong to lose confidence in this very, very reliable car??

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.

I bought a used 2008 prius about a month ago with 44,000 miles. Tonight when I went out to get something out of the car, I noticed a flashing light on the dashboard. It looks like a car but is flashing so quickly I am not certain. I can't find anything about it.

I replaced the 12v starter battery about 8 months or 30,000 miles back. The problem is that It was running fine, and I put the key into it to start and pushed the start button the dash lights would not turn on, the center console lights and instruments work, but the main dash fuel, speedometer lights are out. The car seems to run ok and the main battery bank is fully charged for now.

Last month my red triangle would pop up along with the yellow head light symbol. Most times it would be for a few seconds, other times it would stay on for a few minutes. Today I rotated my tires and I thought I would check out leveling sensor while the tires were off.
I took my left rear tire off and this is what I saw when the sensor was removed.
So everything looked normal to me. Looks can be deceiving. I've seen pictures on here of leveling sensors where the guts are completely rotted out. That's what I was thinking I was going to see. Here is a picture of the bolt side of the sensor:
Again, it looked normal to me. If you don't know what you're looking for, especially if parts aren't mangled, it can look normal. So I took the four screws off of the sensor and this is what I saw:
The inside of the sensor was in pristine condition! The springs are shiny gold and there was only a small amount of dust inside the sensor. I started to think about how the sensor works and I figured out that the sensor must move in some way. Hmmm. But there was no bracket on it to turn the sensor.

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 own a 2009 Prius and have had occasional issues with the car not starting in cold weather and have had to jump start it a few times. Fortunately that was successful. Today I noticed a new problem. In the past we have had problems with the car making a beeping noise, and the car with key symbol would blink. I have ignored that issue as it only lasted a short time. Today the car was beeping and when pushing the start button the car turned on but the dash lit up with the red triangle and exclamation point. We have had this happen before and would press the parking brake, then release it, push power button and it would shut off and we would restart without problems. Today the right headlamp went out followed by the left one about 30 seconds later. The fuel indicator began blinking as well as the drive/park indicator on the far left of the dash. The car eventually went dead although had very little light for overhead and glove box lights. The brake lights also worked. We have 125,000 miles on it with the original battery. Does this mean the battery finally went. If so how will we be able get the car out of the garage?

Little background, I have a 2005 Prius that i've had since 55K that now has 114K on it. I have never had to replace the battery so it could possibly be that but this morning I received the red exclamation and this weird D symbol.

My 06 prius takes a very long time to provide heat to the cabin. In temps below 20 F it can take 20 minutes. Today in 16 F weather the red triangle came on, followed by a problem banner, followed by a thermostat symbol. The triangle and symbol turned on a off a couple of times over a 5 minute span. I had been driving the car from a cold start for about 15 minutes when this happened. The car did start to produce some, but not a lot, of heat at about 20 minutes into the drive. I was also forced to use the defroster intermittently for the first 15 minutes (blew only cold air). After parking the car for 20 minutes I drove 20 minutes home with no triangle or thermostat symbol. Most of the way home I had sufficient heat.
I do have the front blocked with pipe insulation. I have owned my 06 prius for over a year and it has 257,000 on it.
Could the thermostat and triangle be caused by a low engine temp? If so would a stuck thermostat be a potential culprit?
Can I assume that if my car is blowing cold air when I am asking for heat that the engine is not over heating?

2 days ago, with no warning, my 2011 Elantra Touring wouldn't start. Just wouldn't turn over.
I noticed a dash light with the symbol of a key inside a car was on. It would stay lit up at all times except during the start up attempt - even with the key out of the ignition.
I looked it up and have been reading about the immobilizer. Apparently this might be my trouble. Problem is, how to troubleshoot.
Here is what I have tried so far (turn-key ignition)
- verified car was in park.
- tried to start in neutral.
- jump started the battery, even though it didn't seem to be a battery issue.
- left key turned to start position for 15 minutes, then tried to start it. This was recommended in a thread on a different forum for a similar sounding problem.
Will try to post a video of the dash during a start attempt in a few minutes.

My wife drives a 05 GX470. Is there a way to disable the caution message (i.e. Caution: Drive safely and obey traffic rules...) that appears on the navigation screen every time you start the suv?
