I have a 2005 prius with 84,000 miles. The car is running fine but the main red triangle light came on. I took it to toyota and they said I needed a new hybrid battery.
View 10 RepliesI 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.

I was able to pull codes this evening ( no subcodes).
The codes are as follows:
P3000, Battery Control System Malfunction
P3030, Battery Voltage Detective Line Snapped
Will the P3030 cause a P3000 to pop up since it appears I have one of the 19 voltage detect lines corroded or broken?
Once I fix this issue, is there a chance that the P3000 will disappear?
I was just getting the triangle and the Main Battery error on the MFD up until yesterday. Yesterday, the ! with the car came on (Hybrid system) on the MFD. I did not check any codes until today. Car will currently not start at all.
Aux battery voltage is confirmed to be 12.3 volts via the MFD in the diagnostic mode so it's good to go.
No one around has a scan tool that will also pull the subcodes.
My dad has a 2015 Prius v Three (lowercase v and three, not III). He just hit 7,500 miles. He had the service done at 5k miles. The error message that popped up on the dash today says, "Maintenance required for hybrid battery cooling parts at your dealer"...
View 4 Repliesi have a 2006 with almost 200k miles. Got the red triangle, check engine light, and the red car at the top of the MFD. I ran the codes and got P3000. Does this sound like traction battery failure? The car still turns on and ICE still cycles off and on.
View 19 Replieswell I saw one other thread on this topic but no resolution. I replaced the hybrid battery like the codes told me too on my 2003 prius and it now drives great but as soon as it start it shows a problem and the red triangle stays on. No check engine light, no codes, no driving issues just a red triangle. How to diagnose a red triangle when there are no codes.
View 16 RepliesI have a 2007 Prius with 107k miles. Last July it had a minor drivers side front end collision. Last November it had the hybrid battery replaced. I believe all this is unrelated just putting it out there for information.
I am currently having the red triangle pop up intermittently. When it does a "problem" message will display on the MFD. This seems to occur most often after a long downhill or when the Energy display is showing the hybrid battery is nearly full.
The hybrid battery seems to be functioning normal and the car is driving normal and has expected fuel economy. I do have a headlight that cuts out occasionally but no other noticeable electrical problems. I do not have a diagnostic device to get the codes.
I replaced my hybrid battery of my NHW10 a year ago. now recently it shows the warning triangle. Once it went off after a long drive but now its permanent. is there a way to Diagnose what is the cause of this? If its a Hybrid battery issue, will it go off if i replace the bad cells?
View 3 RepliesI 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.
View 9 RepliesI 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 RepliesI 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?
View 3 RepliesThe last few weeks I've been noticing that, upon start, the hybrid battery is showing at 1 line. It's been really hot in SO cal and the air con has been blasting, so I've been letting it charge up a bit before driving. Once I'm on the road, the battery charges fine and seems to hold a charge.
View 10 RepliesA few days ago I was driving my 2005 Prius aggressively up a mountain road and all at once the hybrid system warning light, the triangle with the exclamation point, and the regenerative brake system warning lights came on.
After about 2 minutes parked, I restarted the car and the regenerative brake system warning light went off, but the other two were still on. I still drove it twenty miles home, over another substantial mountain gap (about 1000 ft up and another 1500 down), without any problems.
I checked the voltage of the 12v battery, which seemed to be on the low end, but OK. (I think the lowest reading was 11.9). There seemed also to be some turbulence in the inverter coolant reservoir.
I brought it into the electronic vehicle specialist in town here today, who pulled my codes and said that the hybrid battery was dead.
Possible hybrid battery failure in my 2004 Prius (96K miles).
Sunday before last, the check engine light, warning triangle, and hybrid warning light came on when I started my car at the grocery store.
Because I was close to home, I drove home and the car functioned completely normally. The next morning, when I started the car, the same warning lights appeared. However, when I tried starting my car with the headlights off (I always leave them on), no warning lights appeared.
I took my car to an independent mechanic. This is their written report:
"Found multiple check engine codes, P3000, sub code 123, V0100 sub code 211/330. These codes are set when high voltage control detects a malfunction in battery pack/ECU assembly. To check battery pack we took vehicle out on a test drive while monitoring the cells in the battery pack. Found that they are all weak and drop fast when battery is put under a load. Code C2318 is a low voltage error/power supply malfunction code with the auxiliary battery. The voltage spec for setting the code is 9.3 volts, this battery is less than 9.2 volts."
In conversation, the mechanic also told me there was significant voltage variation across the cells in the hybrid battery.
I then took my car to the dealer to try to confirm this analysis. They were unable to read any codes because the independent shop apparently cleared them. The dealer was unable/unwilling to do more than read the codes to diagnose the problem. (Indeed, they seemed surprised that the independent mechanic could monitor the cells in the pack.) All they did was to drive the car around some more to see if the check engine light would come on. It did not.
The car has been driven 80 miles since the warning lights last appeared and appears to be behaving normally. From your perspective, does the report from the independent mechanic make sense and is it believable? And is their test under load definitive of a hybrid battery problem? Could the results be affected by the low auxiliary battery? Also, if I do have a hybrid battery problem, what are the chances of being suddenly thrown into limp mode while driving it?
I changed my oil, oil filter, air filter at 90k for a trip to Miami this past weekend. Uneventful on the way up. On the way back, stopped and did some shopping before hitting alligator alley to come back home. As I got on the alley after paying the new $3 toll my 05 prius with 90k miles on it would not go over 65 with my foot on the floor and the battery on the mfd was in the pink. So I drove to the nearest exit, checked the fluids etc, all good. Got back on same thing so I put on hazards and stayed on until i could get off on a much slower road. I was going about 55-60 and it would go no faster.
As I got to a place I pulled over DC'ed the negative battery cable and let it sit for a half hour. I then attempted to get going and it seemed to be running fine until I attempted to pass a car and the car seemed to lock up and lose all power, check engine light came on and the red triangle light came on. I pulled over and let it sit again. I then got it to a gas station with the check engine light on. I put a few gallons gas on and tried to limp it home. It made it home and the battery seemed to recharge back to all the blue it can get to, but has yet to hit the green.
I bought a 2005 prii with 145k miles about a month ago and have since driven it 1,200 miles. A few days ago, the red triangle light came on when I started the car in the morning. I had to get to work so I unplugged the negative on the 12v and reconnected it. It started and it drove just fine. I get off work and the same thing happens. I did the same thing and drove home just fine. I then ordered a optima yellow top from elearnaid and it was shipped and arrived in 1 day!!!
I installed the battery this morning and called the dealer to notify them of my situation. The light didn't come on so I thought it may just be the 12v. But of course I didn't wanna run out of warranty and then the hv battery completely goes bad. The dealer tells me to bring it in and I did. They "diagnosed" the car and could not "repeat" what had happened to me. They said because I unplugged the 12v, it erased any codes. I thought it's always saved on the ECU? anyways, I told them about installing a new 12v battery and they said, "that must be it." I'm at 147k miles right now and I don't want my 150k / 10 year warranty to expire before something really goes wrong with the hv battery.
Am I just screwed and hope for the best for miles to come? Or is there a Toyota number I can call to tell them of the situation? I'm almost hopeful that it was only because of the 12v but at the same time, I have doubts.
But while driving the hybrid warning light turned on in the MTD. A red car if I remember correctly. It was the hybrid battery over heating and to try and mess with the wiring going to the cooling fan in the right rear quarter panel.
View 6 RepliesI just switched out my hybrid battery and put in a brand new one. Now, the car isn't doing anything and all that's on is the check engine light. What now? I was told I had to tow it to Toyota and have them reset the computer. Sound right?
View 7 RepliesJust returned from a mechanic who tested my 2004 Prius with 134,000. It indicated there is a problem with the main battery. I was trying to avoid the dealer but it looks like it is a must. He suggested I ask the dealer to remove the battery and bring it to a place in Clearwater Florida to have them refurbish it. If I try to trade in this car I won't get anything for it with the engine light on, right? What should I do? I replaced the 12V two months ago.
View 8 RepliesMy check engine light came on, I took the car to my usual mechanic, and he said the codes returned indicated that two cells in the batter were bad. (I just called to get the codes, but he's out of the office for about 30 minutes on a test drive...)
View 8 RepliesI have a 2003 Prius with just over 116,000 miles. When my wife cranked it a couple of days ago, the "Hybrid System Warning Light" came on.
As advised by the owner's manual, we didn't drive the car. We took it to the local dealership to be checked out. When I called for an update last night, they said that the computer indicates that the hybrid battery is leaking.
So I guess my questions are:
1) What kind of lifespan is typical of a 1st Gen Prius?
2) How many more miles are reasonable to expect from the gas engine?
3) Is there anything I should be aware of to make sure I'm not taken advantage of? (eg is there a credit for the battery since it has valuable components)
