Prius (2004-09) :: 2006 - Triangle Of Death Came On, Battery Died
Got the triangle of death after letting the car set during my 2 week vacation. P0A80 and Battery block is 14.17V all the rest above 15.35. That's a lot of money to repair a car. Not sure if I want to cut my losses and move on or replace it and drive as long as I can.

Had a company install fog lights on my replacement 2007 Prius I picked up after I totaled my 2008. When i went to pick the car up, the car wouldn't start. Showed the triangle of death and threw a code that the 12v was bad. Probably from having the car off and testing the fog lights continually - resulted in a drained battery. I picked up a brand new yellow top optima battery and thought this would resolve my issues. Nope, once the batter was replaced, the car wouldn't go into Drive or Reverse, only park or neutral. The current code is P0A0D. The shop is baffled. They removed all modified parts and still can't figure out the issue. They are currently replacing the interlock plug in hopes that this will resolve the issue.

I have an 07 Prius which I bought used in 2011 and which has been fine (except for some A/C work last year) but got the 'triangle of death' this morning and having towed it to my regular shop, they tell me the code (they couldn't give me the number) simply said 'replace hybrid battery'... the car has 102,605 on the clock.

I own a 2005 Prius with 233K miles. I got the terrible red triangle of death and several other warning lights. Had the codes checked out at Toyota and confirmed a bad HV battery. I am kinda handy and I replaced it myself. No big job, it took about two hours, most of which was spent removing the interior panels, etc. Test drove the car and all looked well. Thirty or so miles later, BAMMM, lots of warning lights. At this point I took it to my mechanic to have it checked out. They found nothing you wouldn't expect when you've disconnected the two batteries.
They cleared the codes and off I went. Again about thirty miles out the lights went on again. Back to the garage once again. What they found was a corroded connector running to the fan, located under the rain gutter of the hatch, passenger side. Hmmm, how'd that get corroded?? Two years ago I remember drain the sump where the spare's located of 6 inches of water, how'd that get in there??? My mechanic confirmed he has seen that before in the Prius. So now I am wondering, did the initial battery fail because the fan may have failed??? Perhaps we need a warning light.....
Prius (2004-09) :: CEL And Triangle Of Death On 2007 Gen 2 - Replace Hybrid Battery Pack
I have a 2007 toyota prius. The car drives, but pulsates. The Check engine light and triangle of death are on. Diagnostic test says "replace hybrid battery pack", but wouldn't the car not even start if the bat pack were dead? What it could be? perhaps a bad cell or two? a bad ecu?
View 19 RepliesPrius (Gen 1) :: 2002 - Traction Battery Indicator And Triangle Of Death
I have a 2002 with 110,000 miles. Over the past 8 years it has had the check engine, triangle and ! symbols come up a few times. When I was new to the car, I raced to the Toyota dealer, but they never really found anything wrong, so I have become detuned to the issue. It has been years since the last episode, but yesterday the check engine, triangle and exclamation point all came on.
The difference is now the battery indicator will drop from 75% to 25% while idling and I can hear the inverter cooler running. (usually it only runs after driving a long distance). I can see coolant bubbling in the reservoir. After a short while, the battery goes back to 75% and will stay there for awhile during normal driving, but will randomly drop back to 25%. Is this a warning of battery failure and is there anything I can check, or should I take it to the dealer?
Prius (2001-03) :: 2002 Died With The Main Battery Light And Triangle Of Death On
I bought my 2002 prius with 120000 miles. Last night it died with the main battery light and triangle of death on. I haven't taken it to a dealer to have the codes checked out you, but will do it soon. My daughter was driving it when it happened and said the car started shuttering and died. She was able to drive it a few feet at a time before it would die again. Does this sound like a HV battery problem? I will be digging into it tonight.
View 19 RepliesPrius (2004-09) :: Red Triangle Light With CEL Code P0a80
Was driving home from school yesterday and my 2005 Prius turned the check engine light on and the red triangle light. Plugged into the scan tool it read: P0a80. I have a hybrid battery ordered. It should be delivered on Tuesday. How long can I get out of this failing battery before the car is undriveable? The Prius is my only vehicle and I don't have a problem with installing the battery, I just I'm wondering if the car will just drop dead on me before the battery gets here? The car appears to be driving normally with no loss of performance or MPG.

A couple months ago, my car suddenly got the red triangle. The dealership said that I needed a new battery, and eventually a new water pump. I couldn't afford $4500 as I bought the car just 9 months earlier and am making payments on the car.
I found a guy that was to "recondition" the battery, which set me back about $1200+. After getting it back, the car has been making a rattle sound in the engine bay when under acceleration (it sounds like a loose screw, but I don't know).
After about a month, I got the red triangle again. The car's performance deteriorates, the state of charge fluctuates a lot more. One minute it is green then literally a minute later it is purple then green again. The guy that reconditioned my hv battery said all the cells are good but for some reason became unbalanced, so he put it on the grid charger and rebalanced it (I believe it was on there for about 24 hours).
2-3 weeks later, it happens again. Same thing, the guy says it is unbalanced again and stuck it on the grid charger (because of time constraints, it was only on the grid for about 5 hours).
Then again 2 weeks later it repeats itself. A couple days before it happened, I tried out the elm327 adapter, custom pids, and torque app. Before the triangle came on, the delta state of charge got to about 0.9% and was charging up to just about 90% and down to just below 39%. Same thing though, from high to low in a matter of less than a minute. Same code P0A80. Sitting on the driveway, all 14 modules would be consistently within .2 volts. But when the car started acting up, I saw a voltage difference of about 3 volts between highest and lowest modules. The repair guy said the same thing again. The cells are good but got unbalanced again. This time he recommended for me to leave the car for the weekend so it can sit on the grid charger for a minimum of 24 hours, which I did. I picked it up yesterday and it's driving fine right now.
He is also recommending that I buy a grid charger and charge the battery every couple weeks to avoid these problems. I mean, how do I know if he actually reconditioned the battery, or has just been resetting the fault code and grid charging the battery? Btw, I did the auxiliary battery test and it was perfect. I don't know when the battery was last replaced but I believe with how strong it is, that is was done sometime recently before purchasing the car late last year.
Prius (2004-09) :: Warning Triangle Came On And Scanner Show P0A80 Code
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.
Prius (2004-09) :: Check Engine Light / Red Triangle And Code P0A80
I'm guessing that I need to repair or replace the HV battery. But I'm not sure.
Today I drove for about 20 minutes with no issue. 10 minutes later, I got back in the car to drive again. This time, after about 20 seconds into the drive, a string of dash lights came on; Red triangle, VSC, Check engine.
The VSC light went away. But the red triangle and check engine light are still on. So, I had the trouble codes pulled by a mechanic, and the code P0A80 was returned along with a statement reading 'replace hybrid battery'.
Should I take this at face value? Or look for something else first?

I am a new Prius owner. I just purchased a 2008 with 27k miles yesterday, and last night I got the "red triangle of death". My car is currently back at the dealership after a very expensive tow. I only got to drive it for about 4 hours.
Before the break down, I was extremely excited to finally have a Prius, and was really happy with my purchase. I'm still excited about having the car, but I'm also highly disappointed that it broke down the day I bought it! I sure hope this isn't a sign to come! I see that most people love their cars, and I've read that they consistently get high dependability ratings.
Prius (2004-09) :: Triangle Of Death Came On, No Codes Detected
2005 with 123,000 miles. I have owned for a few thousand miles. Car was dealer maintained at every recommended interval. Car runs perfect.
After car sat for a week or so, I drove it and the red triangle popped up along with PROBLEM statement and take to immediately to dealer symbol. Red Triangle and other warnings repeats every once in awhile - will go a day without, and then will come on and off within a couple miles. Car continues to run fine. There are no other check engine lights. I have checked all the fluids and they are fine.
The battery charges fine, and holds the charge overnight. I have a generic code reader and there are no codes. I have read other posts, and there are always problems that seem to come with the Triangle. Gas mileage is fine as well.
Prius (2004-09) :: Triangle Of Death Came On At Initial Startup
I've dreaded the day I would receive the Red Triangle. It occurred upon initial start up this morning.Could this be brake system related as 3 weeks ago I got my front brakepads/ rotors replaced. Since then the front brakes have been grabbing to the point that my wife will ask me about the noise when she's in my car.
The hybrid battery indicator is always many blue bars and green with no wild flucuations. I'm getting between 48-51 mpg's. For general maintenance I installed the Optima Yellow top about 4 weeks ago. Oil is full, coolant inverter reservoir is full with tuburlant motion and was replaced under recall 2 years ago. The transaxle fluid was changed 20k miles ago.
So back to the brakes. I have the Red Triangle with !, VSC.

Prius (2004-09) :: Triangle Of Death Suddenly On Then Off Just As Quickly
A strange thing happened the other day. I was driving in Houston heat (98F), started up the Prius, pulled out of the parking lot with a quick (well, as quickly as a Prius can. . .) turn to merge onto the street, and the Red Triangle of Death suddenly appeared and disappeared just as quickly.
Another odd thing that's happened is the CEL will come on on long road trips immediately after I get gas. Yes, there are elevation changes, but the CEL used to trip then turn off after a few minutes to half an hour. Now, it goes on for over a day.
Prius (2004-09) :: 2006 - Intermittent Red Triangle Of Death
Our '06 has 68K on it. Last weekend I changed the front bumper (just cracked from small accident last year) and changed the oil. Used Mobil 1 5/30 and a Fram Oil Filter.
After about 125 miles of driving intermittent Red T.O.D. Always when ICE is running.
Oil level is OK - not loosing any oil. Filter and bolt on the pan are fine - no leaks.
Prius (2004-09) :: Death Triangle With Lots Of Codes Diagnosed
Upon turning on my car and driving a few feet I had the Red Triangle of Death, Yellow VSC, Yellow (!) Indicator, and check engine light and I'm trying to figure out where I should start working on the issue.
The Codes were as Follows:
P3000 (subcode 123)
C0200
C1241
C1300
C1310
C1259
A little history:
About 3 months ago I had an issue with the hybrid battery and replaced a battery cell which stopped all issues. About 2 weeks ago I replaced the coolant inverter pump and until today there has been no errors, CELs, or any negative performance.
This is a Gen II, 2007 prius with almost 200k miles.
Unfortunately I had plans that I could not reschedule and made the drive to the location and drove back. I had serious battery drain and it was almost always at 1 bar of battery, sometime reaching up to 2 bars. There is also the sound of a fan coming from the back seat, which I assume is the HV Battery fan, but it is on regardless of if I have air conditioning or not. A/C is working fine. When I returned home the battery charged almost up to full bars, but when I came to a stop the battery drained in about 10 seconds leaving me with very low power to keep moving. After that whenever I slowed down the teal arrows showing a recharge of the battery were gone and the battery seemed to refuse to recharge.
Steps taken so far:
I topped off my engine coolant in the front reservoir as it seemed a little low, but I didn't add much before it was full. The other reservoir near the engine was just about full and taking off the other cap showed coolant filled to the top.
I tested the 12v battery with my voltmeter which came back reading 12.7.
Prius (2004-09) :: Red Triangle Of Death - Car Would Start But Only Go Into Park Or Neutral
The car is a 2005 Prius II hatchback @ 70,000 miles. I like my local garage and they have a good reputation but bad things keep happening. I'm ready to lose my temper but I don't want to. Here's the summary:
3 weeks ago - Started getting the red triangle of death. Had trouble starting. Finally, the car would start, but only go into park or neutral. Towed to garage. Garage put in a new 12 V battery. The car drove away from the garage nicely.
