Prius (2004-09) :: VCS / ABS And Yellow Exclamation Sign Came On / Noise When Accelerate And Shaking
Nov 22, 2014
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?

I have had 3 or 4 warnings in the last two days when trying to start my car.
Sometime the red exclamation comes on and twice the mfd came up with a message about 'P' and parking on a flat surface.
I have a 09 gen2 and I'm on my original battery. Was wondering if its an early sign of 12v battery failure or if its something else?

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.

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.

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?

I am driving smoothly on the highway, doing about 60km/hr, with my A/C working on a full. Suddenly, the check engine and emergency brake light comes up on the HUD along with a beeping sounding. A pull over, and smell a bad odor - like burning rubber - coming out of the hood. I checked and the car was immensely heated and there was smoke rising from a small rubber tube right next to the fuse box under the hood. I turned off the car.
Whenever I would turn the car back on, the smoke would start coming back. I checked several times. I couldn't find out where the smoke was coming from.
When the car cooled down a bit, I checked the radiator. The coolant level was a bit low so I filled up with the water. I also noticed that the radiator fans were not working, even when I turn the A/C on. So I called a towing company and got my car back to my garage.
Now the car heats up after running for a bit and the big exclamation mark sign comes on. The check engine light also comes on. But when the car cools down, the lights go away. I am thinking that the problem has something to do with overheating and the radiator fans not working.

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.

After coming back from a two week vacation, I tried to start my 2002 sedan toyota prius; and it would not start. The master warning light came on, and then on the screen, the third icon (the farthest right) was blinking in red, it was an outline of a car with an exclamation mark in the middle of it. It does the same thing each time I try to jump it. However, at the same time, after jumping it, the battery seems to be fine, meaning that the display and radio start up fine, but soon after cranking the key, the engine seems to shut off. I bought the car used, so I don't have an owners manual or anything of that sort.

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.

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.

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.)

"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...

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 ?

I have a 2009 Prius with about 38k miles. Lately I have been observing that the mpg is constantly dropping and has reached 38 now. For the past couple of weeks, I started noticing a weird noise as if something was rubbing against something else. The noise would come and go, as if something was trying to engage. Upon further experimentation I noticed that it was related to A/C - when the noise would happen, if I raised the temp enough to turn off the A/C the noise would stop. After that if I dropped the temp back, the noise wouldn't come back.
Anyway, today all of a sudden I noticed the A/C was not blowing cold air, so I was sure the A/C went down. However after sometime the car gave me red bang, and it says Problem on the screen with car sign and exclamation, and a check engine light. But the car drives just fine.

Yesterday, started it up, began backing down the driveway, controlling speed with a little pressure on the brake. There was momentary weirdness, like the brakes had sort-of let go, then gripped again. And then got the warning "CHECK HYBRID SYSTEM" and a yellow triangle (inverted?) with exclamation mark.
I tried maybe 3 restarts, but the warning persisted. Phoned the dealership, booked-up Saturday, but they said they'd (commendably) squeeze it in. So we brought it in, when they eventually got to it they read the codes, cleared them, test drive, said it appeared the computer(s) "lost contact" momentarily, and it seemed ok.
I got in and started driving home, down the back lane first. Car started making a VERY strange buzzing sound, coming from under the hood. By the end of the lane I decided I better circle back to the dealership, pulled in at the curb in front, left it running and raised the hood, the hood support rod was loose, laying over the engine, doing a dance.

I had a triangle with an exclamation point (not red), a check hybrid system message, and an airbag indicator come on in my car in February. I thought the triangle with the exclamation point was originally yellow but my eyes could be playing tricks on me. It now appears orange.
In February, the dealership told me that some kind of rodent apparently chewed through wiring containing the airbag tether and hybrid system wires. I was told this is a 3K+ repair and was advised to make a claim against my insurance. I am working away from home until June, so I was going to wait until I go home to have my preferred dealership handle the repairs.
Does driving solely on the gas system harm the Prius? Does the car have both yellow and orange triangles with exclamation point warning indicators? By driving the car in the condition it is in, am I harming it and is the possible change in color of the indicator a sign of a worsening problem?

This morning as I was driving to work, my truck hesitated as I tried to accelerate from a stop sign. I pressed the pedal and nothing, almost felt like it was going to stall. After about 3 seconds it started driving again and I had no further issues. It seems to only do this in the morning when it is cold. It has done this a couple of times before, but usually it recovers almost immediately. I had no CEL come on. 2007 F150.....

So after a decent drive when I get to a redlight / stop sign / etc the truck will idle rough and shake but giving it a little bit of gas (1k RPM) seems to smooth it out however it doesn't throw any codes or the CEL. The truck is a 2008 F150 with the 5.4 and 90k miles.
I've searched quite a bit on this issue and I can't seem to find any real fixes other than swap parts out until something works and I've heard everything from filters to cam phasers or low oil pressure (I will be taking it to the mechanic to check the oil pressure)
so far I've:
Replaced the air and fuel filters
Changed the oil and oil filter (synthetic and OEM filter)
cleaned the MAF and cleaned the throttle body
also is 2008 equipped with an IAC Valve because I've read that it wasn't and I can't seem to find the IAC if it is.
