Prius (2004-09) :: 2006 - Multiple Warning Lights / Ready Light Flashed Few Times Then Went Off
I most recently drove my 2006 Prius around on Saturday Feb. 1, with no problems at all. I went out of town for a couple of days, and returned this afternoon to a car that will not start. I stepped on the brake, pushed Power, and things lit up, the "Ready" light flashed a few times but then went off. Power button light stayed orange.
Several warning lights on dash stayed on (!)/ABS/VSC/traction control, and a message came on the screen saying something about a problem with "P" parking, and that it should be parked level and the parking brake applied. It is sitting level with the parking brake applied already. Also, the door ajar warning light and beep start as soon as you open the car door to get in.
I'm thinking from what I've read that my 12v battery has died/is dying. I'm the original owner, bought car in March 2006, and it has just under 61,000 miles on it.
Prius (2004-09) :: Three Warning Lights Came On But No Difference In Driving?
So I was driving and suddenly three warning lights came on. The Master warning light (Red triangle with !), Check Engine Light and the Hybrid System warning light (Car with !).
My AC works fine and I was able to shut it off and start it back up with no problem. I also did see a difference in driving.
Prius (2004-09) :: Warning Lights Came On While Driving But Did Not Lose Power
I was driving my 2006 Prius on the highway (120,000 miles on it). I'd been driving about 10 minutes and all of a sudden, the dash warning lights lit up.
Red triangle with exclamation point.
Yellow circle with exclamation point.
Yello check engine.
The car did NOT lose power. It kept driving fine with no noticeable change in how it operated. Fuel consumption stayed the same. Braking worked fine. I had a completely full tank of gas (had just filled it up before I got on the highway). Temperature outside about around 60 degrees.
I kept driving to my destination (another 20 miles at highway speeds). The car sat parked for about 3 hours. I returned to the car, started it up. The same warning lights appeared, except for the Yellow circle with exclamation point. Plus, this time I noticed on the energy monitor screen the graphic of the red car with the exclamation point.
Again though, everything seemed to be working fine. While the car had been parked for 3 hours I did some browsing through the owner's manual and saw a notation that is the warning lights were only yellow and not red that it was okay to proceed with caution to the nearest dealer.
Prius (2004-09) :: 2006 - Multiple Warning Lights Came On
I have a 2006 Prius with approximately 112,000 miles. It has been a merely perfect car until yesterday. Everything was driving normal on my way to the store. When I turned on my car to leave the store a half hour later, the red exclamation point of death showed up along with the check engine light, ((!)) and the VSC signal all came on. Upon reading on this site, I decided to run the 12V battery test through the nav screen and sure enough, I believed that is what it was. I bought a battery and had it put in. I left the shop and and all the dash warning lights went off. When I restarted my car 10 minutes later to head back to work, all of those exact warning lights came on.
I ended up taking it into the Toyota Dealership Service area. They tried to reset the dash warning lights by pulling out the battery fuse (I think that's what they are called) in the front box of the car. It didn't work so they gave me the option to pay for the diagnostic ($98) or leave and drive around and hope everything is fine. I wanted peace of mind, so I had them do the diagnostic.
The assistant service manager came back 1.5 hours later and told me he had bad news. He said that there were faulty cells in my hybrid battery, which is why the service lights remained on. I almost started crying, sharing that I had thoroughly researched the prius before buying and that this forum, specifically had almost no talk of this...that is rarely if ever happened, that it needed to be replaced. He said in his 15 years at Toyota he had only seen it a couple of times. He told me warnings to look out for is if my car won't go above 25 miles an hour or it could technically start using only the gas side of the engine. He also said that the car just needs to "relearn" how to operate after replacing the 12v battery and it could essentially be fine.
He then quoted me $3500 if I ended up down the road of needing the battery replaced.
Prius (2004-09) :: 2006 - Battery Replaced, Warning Lights Came On
2006 Toyota Prius 93000 miles
On 3/8/13 my Prius would not start. I read some information online and came to the conclusion I needed a new battery.
I started the car, and it immediately started up. I drove it for a very short time and parked it in the garage.
Today I started the car and drove it for about 5 minutes to a restaurant. I did some shopping and about 3 hours later I started the car and A Big Red Triangle appeared along with a yellow circle with an exclamation point in the center and the check engine light.
I immediately drove it to the Toyota Dealer 5 blocks away.
Prius (2004-09) :: 2006 - Dashboard Illuminated With Too Many Warning Lights
I finally found the Prius I wanted. It's used. 2006. Gen II 220k miles. Bought at auction almost completely dead and no gas. After adding gas and driving so the main battery charges. It starts up great however the dash looks a little scary with nearly every warning light on.

My partner drove the Prius with 54,000 miles to work this morning as he always does. So he is on lunch and sent me a text saying some warning lights appeared on the dash while he was sitting at a red light. I asked if he had any loss of power, if the battery fan was running, he said it drove normally. We bought it last summer with 44,000 miles from a Toyota dealer. They said it had a new inverter pump. It has the original 12v battery however. Though it doesn't act weak at all. No issues this winter at all.
Note, the battery in the photo is at 1 bar. I asked him about it and he said he was driving aggressively to work today, which includes a 2 mile 6% climb he said he made at a high rate of speed... Though after the exit, he has another mile to work.. So the battery should have built itself up before him parking it.
Prius (2004-09) :: 2006 - Bad Battery And Tons Of Warning Lights Lit On The Dash
I bought a 2006 Prius with a diagnosed bad battery and tons of warning lights lit on the dash. Toyota had diagnosed a bad hybrid batt and ECU. (I have not replaced the ECU). The car was driving and running fine otherwise.
View 12 RepliesPrius (2004-09) :: Transient Warning Light Appear During Driving
I had a transient warning light appear on my 2008 Prius during a recent drive from the Portland, Oregon area to Seattle . The reason I'm posting this is that this icon isn't listed in the owners manual, nor does it come on when you start up (boot up) the Prius. Also this warning is on the same line as the "ready" and air re circulation icon. On the right side of the display ( the usual low pressure tire, and I think traction control warning icons are on the line below).
This occurred about 135 miles into my drive at the infamous Interstate 5 as you enter Tacoma, Wa ( stop and go traffic) the icon is yellow /Amber a box with 3 yellow squiggle lines which are vertical and cross just past the bottom of the box. After about 15 minutes the warning light went out. It never came back. I have 115k miles and car was recently serviced. I wonder if this is some air flow / ventilation warning. I am overdue to check cabin AF but am unaware there would ce a warning for that. The AC seemed just fine and no effect on the cars performance. Weird.
Prius (2004-09) :: 2006 - Warning Lights On When Restart And Drive After Filling Gas Tank
A couple of days ago, I was about to take a long road trip. Stopped to top off gas tank (yes, I squeezed the handle a few more times than I probably should have). Restarted and drove about 300 feet. Master Warning light, check engine light, brake light and pretty car with ! in the display all came on. Drove home - car ran fine but the hybrid battery seemed to stay full, switched cars, got home the next afternoon, started car again -- all lights still on. Checked gas cap (just in case), brake fluid is between full and low, coolant is probably a little low.

I can't seem to find my manual, and I'm not sure if I should drive my car home after a warning light came on during my drive to work. It was a yellow exclamation point within a bracket. What this means?
View 10 RepliesPrius (2004-09) :: Five Warning Lights - Car Shuddering Strongly At Red Light
I’m facing what might be a major issue with my 2007 Prius, 80k miles, very well cared for with no major issues or accidents. The problem started a few days ago, when I drove my car for the first time in a week, so it had been sitting for awhile. This was after a month-long cold spell in which temps were often close to 0, with lots of snow, and I keep my car outside, which means many days of scraping ice and snow off the car with it running (along with the defroster and heat). I only work part-time, and the car often sits for a few days or longer at a time without being driven.
The problem is this: I was on my way to work a few miles away and was stopped at a red light, and the car all of a sudden “shuddered” rather violently, with what sounded like the engine revving up, then switching back to silent mode, then revving up again, and so on. It freaked me out, but the light turned green and the car drove normally to my destination. Then, on my way home an hour later, a bunch of warning lights showed up: master warning, VSC, check engine, brake system, as well as hybrid system light on the center screen (car with ! through it). I pulled over, turned off the car, waited a bit, turned it back on, all the same lights were on. Drove it home with no problems. Turned it on the next day, same lights.
I decided to drive the car around for a bit to try and charge up the battery, in case that was the issue after all the cold weather and sitting around not being driven regularly. After driving it around, turning it off, then turning it back on, the brake system and VSC lights disappeared, but the rest remained. I continued driving the car for another day, and it did that same strong shuddering thing with weird engine noises while at one red light, but drove normally otherwise.
I then researched a bit more and found out how to check the health of the battery myself by holding down the display button, turning lights on and off three times, etc. The three voltage readings were all within the proper range. When I turned the car back on after completing the battery check, all of the warning lights were gone. I figured the issue had been the battery after all and that driving the car around had brought it back up to normal voltage, with the battery check resetting the system. BUT today the car did the same strong shuddering with weird engine noises while stopped at a red light. I continued driving and made it home just fine, without the issue occurring again, but this is the third time it’s done this in a week, and I’m a little freaked out by it.
Two notes:
*A little over a year ago I replaced the original battery (which died) with an Optima yellow top battery made for the Prius.
*Several weeks ago, after a major snow/ice storm, I was driving home from work when I went over either a deep pothole or hard ice formation, and the impact was really loud and scary—I actually screamed. But the car continued driving normally all the way home, and I examined the wheel area and surrounding parts with a flashlight and nothing seemed out of place. I drove the car a bunch of times in the following weeks with no issues, so this incident is probably unrelated to the problem I’m experiencing now, but I though it worthwhile to mention.
Prius (2004-09) :: 2006 - At Start Up Master Warning Light / Brake Light Comes On
We recently purchased a used 2006 Prius. The vehicle has approximately 74K on it now. Well the other day my wife went to leave work and pressed the power button while pressing the brake pedal, and the Master Warning Light and brake warning light both came on. The car would not allow her to shift the car so she tried to turn it off and it wouldn't do that either. After about 5 minutes she finally got the car to turn off, and when she restarted the sequence everything went back to normal and she drove home fine.
We called 2 dealers and they both seem to be confused by the symptoms, but one thought that maybe the battery was old on the transmitter. So thinking that might make sense I replaced the battery with a new one.
Prius (2004-09) :: Yellow Brake Warning Light Turns On For About 8-10 Minutes While Driving In Rain
Yellow brake light turned on while driving in rain, then for some reason turned off. I had read somewhere this may be an indicator of wear on brake pads. I have a 90 mi. commute round trip, I will check again if this turns on and stays on. For now, it is off. what could be causing this?

I have an '06 Prius with ~170k miles on it. I bought an extended warranty, and it's scheduled for diagnostics for an AC issue next week. However, I was driving my wife to work when this happened ...
Cruise Control shut off, but the car handled just fine. We weren't far from our destination, so I got her there, parked it, and shut it off. I powered it back on after a minute or two, and only the check engine light came on.
I haven't checked the fuses yet (too dark and too high traffic where I am), and I'm not the most knowledgeable when it comes to cars.
Prius (2004-09) :: 2006 - Master Warning Light Came On / Car Died On Freeway
My master warnIng lIght came on In my car.I took my car into Hooman Toyota in Long Beach, California. They did a diagnostic test and performed their MPI WORLD CLASS INSPECTION. While I was getting it tested they said the invert water pump was under recall. No biggie. Nothing was found in the diagnostic and the recall was fixed.
Two days later I took my car to Palms Springs. While I was driving out there the master warning light came on. I started to lose power but it seemed like the computer would reset and it would be ok for about 15 minutes. I even lost power in the engine. I finally made it out there and figured it just needed to rest. 6 hours later I took off for home. 10 minutes into it the lights on the dashboard came on. The car lost all power and I was stranded off the freeway. My battery was down to 1 bar. I left it there overnight and had it towed to the nearest Toyota dealer. They said I need a new battery and that theirs bad gas. They wanted to replace the fuel tank. I replaced the battery.
The next day they said that wasn't it and was going to continue searching. I ended up towing it to my mechanic. He said there was no coolant and the headers are blown. He said I was better off getting a new engine. Let me take you back two days when that WORLD CLASS MPI INSPECTION was done. There was an 8 page report specifying what was passed on the inspection. The battery, coolant levels along with other fluids passed. Not to mention hoses and clamps and about 30 other things. I feel something was missed in that WORLD CLASS INSPECTION. I feel they are responsible for the car ending up the way it was.
Prius (2004-09) :: 2006 - VSC / Brake / Master Warning And Hybrid Light On
I just purchased this vehicle from a private owner, and the first day everything seemed fine. After a few days I get all these warning lights - Master Warning (Red Triangle !), VSC, and the Brake Light, plus the NAV screen shows the red car with ! in it. The car seems to run just fine though. I don't notice any performance issues. One thing I did notice when I purchased the vehicle, the previous owner had a batter charger in the trunk before he took it out.
Now I've check the batter using the LAN Monitor and it shows like 12.1 volts when I turned the car on (not started). I decided to give the batter a deep charge overnight (2 amp charge) after disconnecting NEG terminal from car. It cleared the codes for a little while, but then they came back. My ODB II tester shows no codes, only codes I found on the LAN Monitor was for NAVI - 01-e3 sub 00-5. Do I need to replace the 12v Battery?
Prius (2004-09) :: 2006 - Loud Beeping Sound / Hybrid System Warning Light
I have had no issues with this car of 120K miles until today, although my MPG has decreased to 35 MPG. The following lights came on with a loud beeping sound : Brake warning lights, malfunction indicator light, master warning light and the hybrid system warning light. These stayed on for 25 minutes and then went off. I drove 12 miles without any issues with all the lights and sounds beeping.

In my one-owner purchased-new 2005 Prius w/ 74K miles and w/ no maintenance/accident history other than doing all scheduled maintenances at Toyota Dealers along w/ recalls applicable at each time (other than we had Toyota replace the 12V battery last year just because I knew it would die at some point anyway and I don't like pushing my luck; I'm not 100% certain if there's been a recall on any water pump for this car and if so, don't believe the dealer has mentioned it), I have the following indicators which appeared all at once while I was driving along at around 45 MPH in no unusual circumstances (80F, dry afternoon, about 30 minutes into a trip of mixed speeds, no loads in the vehicle, no effect on the car while driving):
From Left to Right on the display:
1) Red Triangle - Master Warning Light
2) Orange (Symbol)CHECK - Malfunction Indicator Lamp
3) Orange (!) - Brake Warning Light (but it didn't highlight the word 'Brake' in red)
4) Orange VSC - Vehicle Stability Control Warning Light
On the Screen:
Orange Car w/ the ! symbol - Hybrid System Warning Light
We immediately aimed for the house (about 5 miles away); the car drove perfectly fine, with the engine stopping and starting at lights as needed, with speeds going from the 55MPH we were traveling at the time of the alarms down to 0 and back up thru 35/45 MPH and such per normal off-interstate driving. The battery currently shows all the blue bars, and the engine and hybrid systems showed charge/discharge as usual as we drove. There was no discernible change in the driving reaction of the car to brake, steering, accelerator, etc.
