Prius (2010-12) :: ICE Start And Immediately Shut Off Within 1 Second When Hit Power Button
Nov 15, 2013
I have a 2013 Prius Three. If I drive somewhere (engine completely warm) and stop, like at a store, come back 5-10 mins later, hit the power button, sometimes the ICE will start and immediately shut off, like within 1 second. It can't be the warm up cycle as the ICE is at normal operating temperature. I guess it is not a issue, as one of the 20 computers is doing this and there are no lights(like cel).

I have a 2007 with 46,000 miles. Today I went out to run an errand and when I got to the store, the start button would not shut off. At the same time the dashboard went dark so no speed or mileage could be seen, but no warning lights came on. I tried pressing it repeatedly to no avail.

On Monday evening my wife left our 2010 Prius Gen III without pressing the "off" button. She took the keys with her and she claims that she locked the car.
On Wednesday morning I noticed that the dashboard panel was switched on and I deduced that the Prius has been running all the time, with the ICE engine kicking in now and then to keep up the Hybrid battery level. A quick call to my dealer confirmed this, and also the fuel consumption average was in line: 14 l/100 km on a 20 Km trip (my average is 3.9 -4.2 l/100km...).
I was very surprised to discover that the Prius does not switches off when the key is removed (i.e. taken far away from the car). This seems to me a sort of engineering flaw.

My Pris 2010 would not start this morning. My wife tried to start the car this morning and it would not start. All the symbols on the display light up and would not go. She then tries to turn off the car, but the Triangle symbol with the exclamation mark within it lights up. The Start button light is red and the Park button flashes green. Added to that is the constant beep that you hear when you try to close the door with the keys in the car. I cannot even turn the steering wheel. I had to get it towed to the Toyota dealer and am was told that i would hear back tomorrow.

THE PROBLEM: Our Prius 12V aux battery died after my wife left the light on inside the car and instead of buying a new battery, we decided to try jump starting it. My wife tried jump starting our Prius with the neighbors pickup truck and even though I wasn't physically there to witness it, I'm pretty sure that the polarity got swapped during the process. It wouldn't start afterwards, so we went out and bought a brand new 12V aux battery. The prius still will not start. No electric components seem to work (door locks, back brake lights, windows, radio don't work). The dash only shows the orange exclamation mark and the check engine light, nothing else. The power button blinks orange, never goes green.
TROUBLESHOOTING that I've tried:
1. Checked the big 120A fuse right on the positive + terminal. Visibly looked good.
2. Checked all the fuses by the drivers left knee. All tested good with resistance + visible checks.
3. Checked all the fuses in the fusebox under the hood. All tested good EXCEPT the big relay integration fuse under the white plastic cover. It was definitely blown.
4. Replaced the relay integration, still no luck, same exact symptoms.
5. Tried force starting the car in emergency mode by holding the brake and power button down for 15+ secs. The engine starts, but the dash is still dead showing just the check engine light and orange exclamation mark. Can not shift gears or drive.
6. Tried slow charging the NEW battery to get the voltage higher, still no luck. It's testing about 13V with everything off.

Recently, my 2007 Prius will make a "BEEP" when I press the POWER button to shut down the vehicle. This doesn't happen all the time, but only 1 out of 25 times or so. Other than the beep, I can't seem to figure out what's wrong. Everything seems to work as normal.

My dashboard goes out periodically then magically is restored. They say to replace that. I've decided just to trade it in and get a non-Prius. This morning, however, after driving for a short time, I pushed the power button to turn off the vehicle and it only partially shut off. The key wasn't in, so I put it in and tried again. Now it says there's no key in the ignition and still will not turn off nor turn on.

My 2005 vw GTI doesn't like to start in the cold. It will start and I can rev it just for a second before it turns off again. My ABS and ESP traction control lights are on and they only turn on when I have this problem. Normally when it does this I can let it sit for a couple of hours and it will start as if nothing was even wrong. I took it to the dealer to do a full diagnostic on it and the only thing they could find was a faulty instrument cluster and I don't think that is what is causing my car not to start.

My 2006 6.0 shut off immediatEly after starting this morning and never started back up. I have a scan Guage 2 hooked up. I'm showing no ficm voltage and no sync even when cranking. I physically checked the ficm voltage with a dvm at the screw to the far right on the ficm, and I have 48 volts. Why do I have 48 volts at the ficm, but 0 volts showing on my scan guage? And no sync when cranking?

I heard a new beeping behavior this morning. Four beeps when I pushed the start button. Just wondering what this means and why it beeped four times instead of one?

Having that flash on the dash? Truck was running fine and the buzzer when off and dash said I think -- when safe stop and shut off engine immediately. Scared the scr-p out of me so not sure if that was word for word. Jump on the binders and got it off the road and called a wrecker. Now it's at the dealer waiting for them in the morning. Checked oil and don't see any leaks. Now I have lost my confidence in the truck. 42000 miles on it.

I have a 2010 Prius Hybrid and lately, on an intermittent basis, I will press the brake pedal and push the start button and the dashboard lights up as normal but when I go to put it in gear nothing happens. The last time it happened the fan was running and I couldn't turn it off. It's like the car is all set to go but all the interior controls don't function. I then shut it off and restart it and everything works.

I'm about to take delivery of my new 2010 Prius IV. With the winters we get here, in my current car, there are times when I need to shut off VSC to power (read spin) up a hill instead of the car cutting power and leaving me stuck on the side of a hill. I have checked the manual and I do not see a way to shut this feature off. Both my car and the wife's have a button on the dash that shuts off stability control for the short term when needed, like in snow/sand, etc.

Just wondering if I should be concerned. It doesn't happen every time, but it sounds like grinding of a gear or something like that. I made a video .....

My 2011 Prius II hasn't had any issue for the 3 years I've had it until two days ago when the car simply wouldn't turn on. The battery would "whirl" when I would press on the brakes but when I pushed to power button nothing would happen and the Ready light would never come on. The power button didn't have any color (orange/green). The batteries were charged and would spark when cables were connected to them.
I tried it again about an hour later and it worked fine. I drove it for a couple minutes and parked it hoping that it was a fluke. Another hour later I tried to start the car and the same problem as earlier happened. I decided to tow it to the nearest Toyota dealership to get it examined/fixed, but after they've had it for 2 days now they cannot get the car to reproduce the same symptoms.

So this has already happened to me a 2nd time so far.
I depress brakes and hit the power button once when I first drive it in the morning after the Prius has been sitting for a while.
Instead of the power LED turning green, it turns red/amber, and the ready light does not show up blinking or come on at all. To me it almost appears to be in IG-ON mode.
I hit the power button again (can't remember if my foot was on the brake) and all the accessories shut down/car shuts down and I see the shifter indicator on the screen.
I then try to start again by depressing brake and hitting power button once. Now everything starts up fine and the ready symbol is there.

This started about 2 months ago. About 10% of the time when I depress the brake and press the Power button, all the dash lights come on except the Ready light (it acts as if I pressed the Power button twice without my foot on the brake). When I depress the brake a second time and press Power button again, the Ready light will still NOT come on. I have to press Power button with foot off the brake to shut off the dash lights (the car is effectively off) and then when I press Power button with foot on brake a second time, the Ready light will come on. I effectively have to try to start the car twice. I also noticed that the interior lights are dimmer when I open the driver's door until it goes through it's normal noisy gyration (something to do with the brakes?). I'm thinking that the 12-volt battery is starting to fail. Does my Gen III 2010 Prius have a diagnostic tool to check the battery?

2006 when started, the lighted ring around the power/start button is red, where I guess in the past it would light up green.
The closest thing I could find to suggest what it might mean would be a bad 12v battery. Those articles I found relating to the 12v battery said the car would also have the red triangle light lit up in the instrument panel along with the red ring around the power/start button.

Several tries at power button failed. Icon on dashboard (small car image) flashing whether nor not I was in the car. Lights worked and emergency flashers worked. After many tries, called AAA. The AAA driver got in the car and it started right up and has worked ever since. Called dealer. Never heard of such a thing. What happened.

My Prius engine wouldn't shut off when the button was pushed. The Toyota dealer was clueless.

Have a 2001 Prius going strong except for the ac. The button light blinks on the ac switch, and the compressor seems to shut off. But some times the ac works fine.
I brought it into the dealer and they said I need a new compressor.I think it's a temp sensor, otherwise, why is the ac nice and cold and can stay on for some period before going off.
