Prius (2004-09) :: Intermittent No Start - Check Engine Light / VSC And Triangle On
Mar 19, 2015
So let's start with this. A week ago my dad went to start his car after going to the store. I wasn't there so can't say exactly what happened but when I got there the car would basically go into accessory mode with check engine light VSC and triangle on. Also displayed problem on the screen. I checked 12v battery with just the radio on (one button press with foot off brake) and it only showed 12.0 volts. So I hooked our jump box directly to the battery and it still wouldn't start. I scanned it for error codes and it showed nothing but I could erase them and the lights went off so probably codes from one of the hybrid computers I can't read but the car still wouldn't ready. I unhooked the 12v for about 30 second seconds and the car started fine without the jump box hooked up.
At this point I don't have any codes and with nothing to go off of I'm at a loss. We drive it 8 miles back to our shop and it drove normally with no errors. Once it was back in the shop after turning the car on and off 10 times or so still no errors. On the last time it was in ready mode and the errors came back on, still with no codes I could read. His 12v optima was still under warranty so we got it exchanged for free even though I was reluctant that it would fix the issue. Well a week went by and all seemed to be fine until yesterday.
My dad had left the car in ready mode for probably 20 minutes and when he got back in it all the lights were on. I will also add that the battery fan was operating normally and not screaming like if there was a traction battery issue. I changed one of the modules in his traction battery about 6 months ago when one failed. Without any codes I don't know where to start with this problem. 2005 with 170k miles....

Just got a diagnostic from the nice people at Prius Battery Repair. Check engine light was on and intermittent red triangle when I make a left turn. Code PO505 came up- Idle control System. I have 162,000 miles and just put in a reconditioned battery that checks out fine.

This Prius is an '04 with 156k and it will only start with a jump box. I went into the display and found the 12 volt battery reading 12.2 volts after sitting for 4 hours. When driving stop and go around town I will get the red triangle of death and vsc lights but NO check engine light comes on. Using a Scangauge it shows no codes, system ready. I look into pending codes and there is nothing. However when I force clear pending codes the triangle goes away.
It's strange there are no codes associated with this fault. I'm thinking to drive it and not force clear the pending codes and maybe a code will show up eventually but I'm not sure.

My beloved 2006 Prius with about 117,000 miles on it needs to go to the shop (I'm not a DIY mechanic). As I was driving home yesterday from work, all of the sudden the red triangle, VSC, check engine and a little car with an exclamation point on it on the display came on about 2 miles from home. There also appeared a kind of wind sound from the passenger rear area when this happened.
I drove it home and pulled into the driveway. Lights, radio, etc all work. I stopped it for about 30 minutes and then started it up again to pull it in the garage (all warning lights still on).
My question is can I drive it safely to my wonderful mechanic's shop about 10-15 miles from my house (assuming it starts)? I don't want to further damage anything.

I have a 2007 prius. I was driving home all a sudden I get a big red triangle warning and the engine logo came on. On the display screen its show a logo of the car at the corner in red with exclamation mark. I use the car obdII scanner but no error code came up. I decide to check the engine oil. When I remove the cap, I notice inside the engine it look weird like a gold color and some blackish. The engine cap inside look like it have stains on it too. The hole where you pour the motor oil down I notice that piece inside don't go down for the funnel to stick in. I attach some pictures. I have no clue what's wrong with it and I don't wanna drive it to make it worse. The prius only have 90k miles on it.

2006, 2G, 43000K. This has happened twice now. Both times on an extended trip of 3+ hours in hot weather: Cruising along at about 70 MPH, the engine just quits. RED Triangle; check engine light; and vcs light. Turned everything off. Car would not restart right away, but after waiting 15 minutes or so, the car restarts and runs fine. All warning lights off except check engine light.
Immediately drove to a Toyota dealership where the following codes were found: P0AOF info 204 (Engine failed to start); and P3190 (poor engine power). The Tech checked the EFI relay; checked for oil puddled in intake; and checked for a contaminated MAF sensor. "No problems found"!

I got my oil changed today and thought everything (10 am) was fine with my car. I drove it straight home after the oil change. About 4pm I drove it to work and no problems still. Finally tonight on my way home right as I turned on to my street the car at first seem to hesitate. Slow a bit and I pushed the accelerator. Then suddenly as I pulled in my drive way the engine began to shake as though I was about to stall and the check Engine light came on as well as the big red triangle.
This has happened before. The display being lit up like a christmas tree so but this time the engine shook. I turned the car off, check the oil, which is full and the coolant which is full. The engine has not shook yet ( but I wont leave the car on for a long time to see if it happens again) the Red Triangle has turned off and now only the check engine light remains.
I am going to call Firestone, that is where I got the oil change all I know is that they did a routine check up (unauthorized by me) and told me I needed a new water pump drive belt and tires and a air filter..... So I am hoping they didn't touch something by mistake. I told the man that I would much rather have that done by the dealership.

2008 Prius. I just passed by 5K oil change by a 50 miles or so, so my maintenance light was on, but when I was driving it on the expressway today suddenly the red triangle light and check engine light came on, I immediately pulled over onto the shoulder and had it towed. These are the error codes that were showing up:

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?

Yesterday my 2005's check engine light and triangle of doom came on. Even when I fully depressed the gas pedal, it would not drive faster than 35 mph. While waiting for the tow truck, I read the diagnostic codes. They were P0A80 and P3014. A search on Priuschat showed that the first code is the Traction Battery. Is that the same as the hybrid battery pack?

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?

My check engine and red triangle light came on. I checked the code and it's a battery issue. The code is P0A7F. I called the dealer and they want me to bring the car in for a check. I have about 117,000 miles on the car. They have a service bulletin open. I would like to avoid paying large dollars for a new battery.

My wife and I own a 2006 Toyota Prius that we bought used 2 years ago. a couple of days ago, the master warning light (red triangle exclamation point) and check engine light came on. I took it into the dealer and of course, our hybrid battery was dead - battery and a new ECU required.
Our car is at 99,000 and 32 days out of warranty. Went down the road to atlanta hybrid repair. they were incredibly nice, and said that my computer was fine, but the battery would need to be replaced.

Stopped at ATM when heard a thump under seat and all the above appeared on control panel. Waiting on computer code reader to test vehicle. Any clues to what all this means. Vehicle 2006 with 101K. Recent service as scheduled with coolant and inverter coolant and belt replacement done. No other issues to date with vehicle.

This morning I started my 2008 Prius (approx. 31k miles) and found the big red triangle with an exclamation mark and check engine light turned on.
I drove my car <1 mile to a smog check station where they ran a diagnostic on it and came back with the P0A9C code.
A quick internet search turns up that this is "HYBRID BATTERY TEMPERATURE SENSOR "A" RANGE/PERFORMANCE."

I just bought my Toyota Prius about 3 months. First time I change the engine oil for this car at Jiffy lube and I replace with platinum synthetic oil. After I changing the oil for a week, my has red triangle light, VSC, tire pressure, and check light on. I can not use my cruise setting.My hybrid battery show on the LCD screen charge full very quick and it show the battery is fully charged all the time. When I drive my car for about 15 minutes, it cannot be accelerated and it run like very slow. When it happened, in the LCD screen, the battery was not being charged and did not supply the power to the engine. Then, I had to stop my engine and start the engine again. Then, it run like normally and after about 15 minutes, it run very slow. I feel very sad about this and I think I will need to replace my hybrid battery and transmission.

Our 2008 with 110,000 mi is intermittently displaying CEL. First appeared about 3 wks ago. I took gas cap off and then put it back on and let car sit overnight. Next day and for 10 days no CEL. Then one mornng, at first start, CEL reappeared. Repeated gas cap process that night. CEL disappeared for 6 days. Then CEL came on in middle of day after car had been started and stopped 3 times. Repeated gas cap process that evening with no success. Did the gas cap thing one more time, last night, and today the CEL is off. First time CEL came on was right after a fill-up. Subsequent CEL's have had no relationship to refueling. Car has been nearly flawless for 68 months. Engine coolant pump changed @ 75k. Aux batt changed 24 mo ago.

Check engine light, red triangle with exclamation, and on the monitor a red box with a picture of a car with exclamation came on after changing the rear brakes. I checked the water flow control valve and water pump. Don't know what else to check.

I have a 2001 toyota that I was driving yesterday. I parked my car on the side of the road for 2 minutes to find something in the car. Randomly after a minute of being parked the car suddenly flashed the red triangle on the dashboard as well as the check engine light.
Also as well on the main computer screen where the radio stations normally are displayed a Problem alert appeared. It shows the PS icon, the Battery Icon, and the Red Car exclamation icon. Only the Car Exclamation point is red.
As some basic steps I tried (Because I don't know that much about cars) I opened the hood when the engine was off and cold and checked the air vent filter to see if it was clean. I cleaned just in case. I also check the gas cap to see that the cap was closed tightly. Also checked the tires air to see if that could be the case. Oil was looked at by me and I didn't see anything abnormal as well.
