Prius (2004-09) :: Main Warning / Yellow Exclamation Light And Limp Mode
My wife and I are driving our 2005 Prius with 130k miles and have experienced some weirdness with the car while driving. We've got the master warning light (red triangle w/ !), and another yellow (!) warning light, plus the center display shows a red car with an !. I've gathered that it means something possibly with the brake controller, so when I parked I put the e-brake on.
The car was driving fine with these lights on (we were in the middle of Canadian highways and couldn't stop anywhere) except that cruise control would not work.
Eventually, it actually went into limp mode, where we would floor the pedal and the car would barely accelerate. Pulled over, turned it off for a few minutes, then back on and it drove fine, warning lights still on.
I just replaced the driver's front wheel hub, and I can hear the passenger front going bad, so I'm suspicious that this may be related. Just replaced the 12v within the last few months with an Optima.

I have successfully gotten Techstream running properly and just bought a new brake position sensor and will be putting it in which I am hoping will fix the problem with all the lights.

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 a 2007 Toyota prius base model, it has 49,845 miles. Today i got in, pressed the bake, pressed the on button, and the Red Triangle appeared with yellow exclamation point in a circle, and on the lcd monitor it shows that there is a problem and a little icon of a car with an exclamation point on it.
The car drives and runs normal, fuel mileage seems to be the same, everything looks normal except the lights. One thing I tried to do: I took off the battery clamp and i put it back on, the warning lights were gone, but as soon as the engine kicked in the same warning lights came on.
Prius (2004-09) :: Red Exclamation And Hybrid System Warning Light Came On
I have a 2005 Prius with 135k miles. Yesterday the red exclamation light came on and also the hybrid system warning light. I shut the car off and it came on again. The third time the car started normally and it is driving normally today with no warnings. Does this sound like the 12 volt battery? It is original.

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 / VSC And Yellow Exclamation Lights On With No CEL - Code P0A09
I currently have a 2008 Touring Package 6 with 180k and I am getting weird problems. I am getting the triangle of death, VSC, and yellow ! light. There is no check engine light. On the LCD I am getting the red battery + - icon as well as the car hybrid icon. I scanned it and I am getting a hybrid code P0A09 . All of the maintenance have been kept up and all fluids are perfect. No weird noises and the car is doing 53 mpg. It switches between gas and electric with no problems at all. Symptoms were yesterday with the lights. I cleared the codes and they would come back instantly. Today, I did the same thing and now everything is perfect. I am attaching the pictures of my dashboard lights that were on and the codes I was able to obtain in diagnostic mode.
View 11 RepliesPrius (2004-09) :: VCS / ABS And Yellow Exclamation Sign Came On / Noise When Accelerate And Shaking
We bought yesterday a 2004 Prius with 73K miles. This was (unfortunately) a private sale. When my husband drove back home with the car, the VCS, ABS and ((!)) yellow came on when he reached 60mph and above. He also noticed a lot of noise when accelerating and the car was shaking. The noise is also there at low speed and when accelerating it is so bad and feels like something is rubbing?
This morning, we decided to try the tire pressure to see if this could be the issue. After correcting tire pressure (it was actually very bad), the lights went off and we decided to try it on the motorway. The car was noisy to start off but as soon as we hit the motorway, the sound was getting worse and worse. I could feel my passenger seat shaking under me and the 3 lights (VCS, ABS and ((!))) came back on and stayed on until we got home.
What was the issue in the end? We have spent all our savings in this car and can't really afford expensive repairs few days after buying it. We are just gutted. Oh and we have a 2011 Auris Hybrid with 15K that runs superb. My dad owns a Prius too and so I can tell the noise is just not normal- at the same time, perhaps a 10 yo Prius is supposed to do this noise?
Prius (2004-09) :: VCS - Red / Yellow Exclamation And Check Engine Lights All Suddenly Turned On
While my car was idling in a CVS parking lot, the VCS, Red Exclamation in a triangle, Yellow Exclamation in a circle and the check engine lights all suddenly turned on.
In reading the forums, it seems the two most likely issues would either be the inverter pump (which I had replaced as part of the recall, and I see the fluid moving in the reservoir), or possibly a bad 12v battery (which I had replaced last year with the forum recommended Optima Yellow Top).
I checked for error codes, and there were numerous ones there at first, but I think that might have been related to the old 12v battery dying (I never reset after that). I cleared the codes, and no new codes are generating.
Prius (2004-09) :: Red Triangle / Yellow Circled Exclamation - Hybrid System Failure
My wife was driving our 2009 prius this morning. she said the red triangle, this other yellow circled, light with an ! came on plus in the display window the car icon with the ! came on. Manual states that this is a hybrid system failure.
On very cold mornings the car smells very hot for a period of time. She said this happened again.
I tried to do a reset (turning it off and on atleast 4 times) did not work. So I had it towed to a dealer tonight and I started it again and this time very hot smelling and a whole lot more lights were on, ( brakes lights, almost all of the lights I would say.)
Prius (2004-09) :: Yellow Exclamation Point In Brackets Is On - Squiggly Line Below Mark - Is It Normal
"Yellow exclamation point in brackets is on. Squiggly line below mark. What does this mean?" I did some research and everyone says tire pressure, yet all my tires are the right pressure... SO could it mean something else? I would look at the owners manual, but unfortunately don't have it...
View 12 RepliesPrius (2004-09) :: Master Warning, Check Engine, Yellow Brake Light Came On
2006 Prius with 164,000 miles.
First in the morning, starts fine, 500 feet later I'm turning out of neighborhood and I get lit up with:
Red triangle master light
Yellow brake warning (went away after I did signal check)
Check engine
Maint required light
The maintenance light is on because I'm 5,000 miles out of an oil change. I checked the stick, it did appear low, so I added a half quart of mobil 1 5w-30.
The inverter pump was changed due to recall in 2012, and I do still see turbulences in the fluid.
I have 3 pips of gasoline in the tank.
The 12V is a newly replaced yellowtop from elearnaid. Replaced about 1 year ago.
Prius (Gen 2) :: 2005 Toyota Hybrid System Warning Light And Yellow Brake Warning
I've got some issues with my 2005 Toyata Prius (~150,000 miles). My wife was driving recently and the "Master Warning Light", the "Hybrid System Warning Light" and the yellow "Brake System Warning Light" all came on.
Some quick reading of the owners manual said we should take it to a dealer right away, but because it was a yellow, and not red, brake system warning light it seems ok to drive at least to a dealer. in regard to the yellow brake system light the manual said it could be that: "the regenerative brake system failed or that the hydraulic brake system failed".
Now, I have a cheap bluetooth OBD reader hooked up to the "torque" app on my phone and I thought I would try to see what error codes there were to learn more. But strangely, it did not read any fault codes. I've used this reader successfully on my 2001 Mitsubishi galant, but I'm not reading anything for the prius in this case. I'm not sure if there is legitimately no error code associate with the warning lights or if my app is just failing to read them for some reason.
Prius (Gen 2) :: Red Triangle And Yellow Exclamation Next To It Just Lit Up
Driving my 2008 with 189,000 miles on the congested "freeway" the ominous red triangle and the yellow exclamation next to it just lit up. A quick scan of the OBD showed no error codes and good auxiliary battery, engine coolant Temps etc. And good gas mileage, engine vacuum. I had replaced the spark plugs with new iridium two months ago. When I stopped and checked the hybrid converter had good levels and turbulent flow. The oil had been changed a week ago and checked again at lunchtime. Now only the red triangle shows.

Today i had my front discs and pads changed on my 07 prius and after putting it all back correctly I went to drive the car and my abs , vsc and both exclamation marks where lit up , I've read that this is common and a quick reset on a diagnostic machine should shift them ? Is this correct ?

2001 with about 117,000. Just had it in to get the transaxle fluid replaced for preventative measure. Now I'm getting an intermittent triangle/exclamation warning. It seems to go off if I let it sit, mostly. Runs ok for the most part. But when that comes on, it practically limps on very little power.

My boss has an 08 Tiguan and he got an error light on his dash coming to work today. It's yellow with an exclamation mark in the centre. On both side's there's a solid line and on the bottom it's got a "squiggly" line.
What it might be or if this is something known about them? He states there's no performance loss or anything acting up at all. Short of bringing it to a dealer which will be closed by the time we're both off work I thought I would start here.
