Prius (2004-09) :: Check Engine Light And Red Triangle Warning Came On?
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.

Prius (2004-09) :: Check Engine / Triangle And Hybrid Warning Light Came On
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?
Prius (2004-09) :: Master Warning Light / Red Triangle Exclamation Point And Check Engine Light Came On
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.
Prius (2004-09) :: Triangle Warning With Brake Error - VSC / Check Engine Light On
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.

The red triangle warning light on our 2004 came on and went away again It has 100k miles If I take it to the dealer can they pull some codes and figure out why it turned on We have to drive the car to 600 miles for the upcoming weekend and I don't want to be stranded on the side of the road The car has 103,000 miles We just replaced the 12v battery so I know that is OK
I also saw the following things to check. Is there anything else we should check?
1 - Are any warning lights on besides the red triangle? For example, the red BRAKE light, the amber ABS and VSC lights, or the amber circular icon?
2 - Did you check the brake fluid level? If low, buy a new container of DOT3 brake fluid and replenish as needed This fluid will dissolve paint, so do not spill it
3 - While you are at it, check the radiator and inverter coolant levels by looking at the translucent reservoirs behind the radiator and next to the inverter If low, fill with Toyota Super Long Life Coolant
Prius (2004-09) :: Red Triangle Warning Light Stayed On
This morning I went out to warm my car up for a few minutes because it has been so cold and when I started it the red triangle warning light stayed on and the consumption screen said "problem" across the top with a little icon in the upper left hand corner that looked similar to a high beam headlight indicator. I turned the car off and started it again wondering if it would clear which it did not. I left it running and went inside to get my child and by the time I came out it had cleared itself.
In typing this I recall that I thought it stayed on a little longer than normal the other day and just ignored it thinking it was still in lamp test mode on initial start up.
Prius (2004-09) :: Red Triangle Warning After Engine Swap
I have a 2006 Prius with 186,000 miles. The engine developed a knock. I swaped the engine with one from a junk yard. The swap went well. I reconnected the HV battery and the 12v battery. When I tried to start the car I recieve the red triangle with many other dash displays and (!) over the car in the upper left corner of the system screen. I checked for codes with a code scanner, all I can see is $7ea and $7eb. When I clear them the (!) disapears for about 5 seconds and the word problem displays and then tha(!) comes back. The 12v battery reads 12.4 volts.

I was driving last night and my car Triangle Warning Light and Check Engine Light Went on along with on the nav screen a car with a ! mark in it came on. On The info screen the battery level was changing fast from fully charged to just about empty. The car lost almost all power going about 42 miles an hour. I was able to pull to the side and i waited 10 minutes then tried to turn the car on again. I was able to drive home and the warning lights were still on but at least my car had power. What could possible be wrong?

Yesterday I parked on a very slight slope (the front sat maybe 1 half to 1 foot higher than the rear) for a few hours. It was the end of my carport. When returned to move it forward and park, it was dead. So I put a charger on it and got it started but then the red triangle warning light was on saying that there was a problem with the parking system.
View 11 RepliesPrius (2004-09) :: Red Triangle Warning Light Started Coming On When Stopped
I have an 06 Prius with about 170k miles. The hybrid battery was replaced shortly before I bought the car last year.
About a month ago, the red triangle warning light started coming on when I'm stopped. It usually stays on for a few seconds once I start moving again. The MFD just says "Problem" for a few seconds, then displays the icon for a headlight. Once the light clears, the MFD goes back to its normal display. Originally, it was lighting up once every other day or so, but now it's lighting two or three times per trip. I'm going to have to do something about it, but I'm trying to get my head around what to expect.
My understanding is that the red triangle could mean anything from "The door is open and you're moving. Please close it." to "Your car is about to melt down! Seek cover!". I have an Automatic OBD dongle, and it's not reading any diagnostic codes. But as I understand it, there's a whole different set of diagnostic codes that a "regular" OBD reader won't catch.
I keep seeing reference to ScanGauge devices -- do they read the second set of diagnostic codes? I talked to a mechanic in the area who will read the codes for about $100. Is the mechanic likely to be reading the codes with that tool/is that what a dealer would use to read the codes? Is the dealer likely to charge to read the codes?
Prius (2004-09) :: Spontaneous Door Unlock / Triangle Warning Light
A weird thing happened to me just now in my 2005 Prius -- several times, while driving, the doors spontaneously came unlocked, while the red triangle with the exclamation point flashed on the dashboard. I was able each time to relock the doors from the master switch, and nothing else seemed to happen. At first, I thought I might be accidentally hitting a button on the key in my pocket, but I couldn't reproduce the effect by intentionally hitting the buttons. I stopped at my destination (Home Depot) and hoped the problem would go away as suddenly as it appeared, but it happened again on the way back. I have SKS. The key is a relatively new one that I had made some time after I got the car in 2010 (so 2011, maybe?).

A 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.
Prius (2004-09) :: 2005 - Triangle Warning / Check Engine And Brake Lights Came On
My 2005 Prius with 116K on it has been having some uneven acceleration lately and today the Triangle warning light, the check engine light and the brake light came on at the same time. I had about 1/2 mile to go, so I proceeded slowly and called the dealership which had performed a routine oil chg two days ago. They said that if the lights weren't flashing then I could drive it. They recommended that I take it to AUTO ZONE and put it on the analyzer. This elicited these codes: P3019: no definition and P0A80: replace Hybrid Battery.
I have an appointment in 2 days and I'm wondering about a salvage HV battery since the car is 7 yrs old and over 116K miles.
Prius (Gen 2) :: 2004 Getting Red Triangle But No Check Engine Light Comes On
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.
Prius (2004-09) :: 2006 2G Engine Stalls / Check Engine Light And Red Triangle
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"!
Prius (2004-09) :: Engine Shake And Check Engine Light With Red Triangle
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.
Prius (2004-09) :: 2006 - Red Triangle, VSC, Check Engine Light Came On
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.
Prius (2004-09) :: 2008 - Red Triangle And Check Engine Light Came On Suddenly
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:
