2004 Prius, 149,000 miles. Driving on a highway when suddenly it felt like a headwind was bearing down on me, and a minute later, the red triangle of death and all the other lights came on. Did not totally lose power. Pulled to the shoulder and while waiting for the tow truck, started and turned the car off several times.
After the first few times, the red triangle did not light up, but the check engine icon remained on. The tow truck driver had a very difficult time getting the car into neutral to pull onto the flatbed, and then when he took the car off the truck to park it at the dealership, he said it shifted "hard" into drive.
I don't have a code since I don't own a reader. What this might be? I really, really hope it's not the traction battery needing replacement. I have no training to replace single cells.

One of the frequent stations I listen to, WXRT 93.1 here in Chicago, switched over from the standard "HD Radio" icon to one that I haven't seen yet "HD Radio Live" icon. Not sure what this means but it may be related to how some live HD radio can be paused, on other HD radios. Just a guess. Not sure if this has showed up on other HD radio stations but this is the first time I've seen this new icon .

I notice that my nav now have a icon in it. Where the wide screen button use to be, now there is a "TMC" button. I don't know and can't try it out because it's not highlighted

Today, I was driving on the street when I got the dreaded red triangle icon and the word "problem" appeared across the top of the MFD screen. I then noticed the bars on the battery screen kept lowering down to where they became purple when stopped with the transmission in D. The engine would usually start up at this point, but it didn't. I put it in B and gave it a bit of gas to force it to start up. Once I started driving again, the bars went back up, but it has happened two more times (every time the battery depletes to purple).

I was on my way to work this morning when the car just stopped accelerating (or so it felt), all the dash lights came on, I pulled over to the side of the freeway (I was very lucky). Radio and a/c were still working. Powered off, powered on too soon a couple of times - the red triangle and check engine both came on again. Cooled my jets and gave it a few minutes, powered on and the red triangle was gone, but the check engine was still on. Drives perfectly, no problems w/either gas or hybrid engine.

So I was driving my cousin's Passat 1.8t gls with tip the other weekend when we went to the cottage and I got a strange message in the dash that first said STOP in big letters then Oil Press Stop Engine then Service Manual. So I immediately stopped the car. Checked the oil, it was completely full, looked around didn't see any oil on the bay so I called my cousin and he said its been doing that for a while and sometimes it says Brake Failure and I could keep driving no problem. On the drive home (3 hours) this was happening nonstop.

The other day, I was driving my 2006 Prius on I-20 in Shreveport. As I came off the exit and approached route 80, my navigation display read "PROBLEM", and the car suddenly coasted to a stop. All of this occurred in about 100 feet, so I was lucky to be able to coast the car to the shoulder, because it just died where it stopped. If this had happened while I was on the highway, my whole family would have probably been killed, as there was no way we would have been able to safely get out of the way of the multitude of semi trucks that drive that road.
I attempted to re-start the car, and the red triangle warning appeared on the display, along with the little car with the exclamation point in the middle of it, otherwise known as the hybrid system warning icon. Needless to say, the car would not turn over.
I immediately called Toyota to see if they had any info to get the car going. Toyota was absolutely useless, and the customer service agent said the only recall showing on my model was a floor mat recall. I told him that I knew he was only doing his job, but it was a shame Toyota actually believes Americans are stupid enough to believe the floor mats are the problem. Luckily, we had AAA, so the car was towed home, after a two hour wait.
Diagnostics : I checked all fuses and relays, checked battery connections, and saw no apparent problems.

I bought a second hand 2012 prius v with 70k mileage on it from an official toyota dealer. I was stopped at a red light and suddenly the skidding light went on. I didn't think much of it until i wanted to move, and the car didn't!
I immediately powered off and on, and it did work right away (without the skidding light) so I'm not sure how serious this issue is. but i wouldn't want my car to do this IF i was moving. so far, I'm unable to re-create this.
I took it to a dealer and asked if there was any recall on this issue and they said there isn't. It seems like there is a software issue just like this with OLDER prius, but not my model.

Recently there has been a series of problems popping up with the Prius. Its a 2003 model year.
- About four nights ago the warning icon and check engine light (picture below) popped up upon engine start-up and i noticed a weird idle. It seemed to idle rough. After about 20 seconds of idling the engine would shut off. After about 10 minutes and 6 or 7 attempts to restart the engine the warning lights disappeared and idle seemed to be restored.
- The afternoon after that the same warning icon and check engine light popped up along with the rough idle. After about 10 minutes and 6 or 7 attempts to restart the engine the warning lights disappeared and idle seemed to be restored.
- After this incident it seems like the vehicle is getting bad gas mileage. The picture below shows me getting an average of 25mpg. I was driving very conservatively. Driving the same way i usually do, i usually get 45-50mpg. The vehicle seems to be charging the battery more than usual.

I have a 2001 toyota that I was driving yesterday. I parked my car on the side of the road for 2 minutes to find something in the car. Randomly after a minute of being parked the car suddenly flashed the red triangle on the dashboard as well as the check engine light.
Also as well on the main computer screen where the radio stations normally are displayed a Problem alert appeared. It shows the PS icon, the Battery Icon, and the Red Car exclamation icon. Only the Car Exclamation point is red.
As some basic steps I tried (Because I don't know that much about cars) I opened the hood when the engine was off and cold and checked the air vent filter to see if it was clean. I cleaned just in case. I also check the gas cap to see that the cap was closed tightly. Also checked the tires air to see if that could be the case. Oil was looked at by me and I didn't see anything abnormal as well.

I went to the dealership today with my '05 displaying a master light ( big red triangle) and "problem " posted on the screen with the green "hybrid system problem" box displaying.
The Prius guy had the car plugged into the computer for over 3 hours. It spat out a page and a half of codes, and then after a time distilled the codes to 4 things: a bad hybrid fan motor, the relay, a blower motor controller, and a bad aux battery. The problem is I replaced the aux battery a year ago. So it makes me doubt the entire diagnosis.

I don't understand what this message means. I drove my 2005 Prius to the Emissions Testing station (CO) and they said the OBD wasn't "READY".
The CEL goes on and off 4 times a year. It stays on for months, then goes off. The dealership said to ignore it as they couldn't locate the issue.

I have a 2005 Prius with 240,000 miles. About 4 months ago the triangle warning symbol appeared. A friend and I decided to pull the big battery out of the car and find the bad cells. We did that, replace two and the car worked fine for 4 months. The triangle warning has returned. We have done several things but the triangle remains. We pulled the big battery out and checked all of the cells. We replaced one that was probably OK. The latest reading was 8 volts on cells all but one at 7.9. We cleaned all of the bus contacts. We went into the maintenance mode on the MFD and found the aux battery to be 12.6 volts and under load it dropped to 11.8 with the lights on.
The aux battery went up to 14.1 volts with the car on. The inverter cooling fluid has movement and there is a slight humming which I believe to be the inverter pump running. The inverter fluid was topped off. The MFD showed the battery bars start at about three fourths full, drop down to one bar. With the engine running the battery bars climbed to the top purple. The engine turned off and the bars continued to climb to all green. All of this occurred in about 3 minutes while the car was parked. There were codes on the MFD while in maintenance mode. I understand that these codes are for the navigation system and the audio system.

My wife has a '03 that has been great. No issues. I am a excellent mechanic, on conventional cars and motors. Here's my story:
Bought the car used and working last week. Put in a new 12v Group 26 battery w/conversion. I verified the 12v battery was at 12.8v and when engine was running, 13.6v to charge the battery. Car was starting and driving wonderful for about 600 miles. No shuttering, no shaky starts. Mileage was about 38.6. Anyway, yesterday was driving and all of a sudden the warning Triangle comes on, Hybrid system icon comes up and the engine goes off. I was able to drive the car about 1/2 mile on the traction battery back to my work.
It happened to have a code reader handy and it reads a P3125, Inverter. I realize there are sub codes that further diagnose the issue, but I don't have that type of OBDII reader although mine is a very expensive model. Anyway, I reset the code and got the car to start. Motor begins to go up in RPM and throws the code again. I shut it off, reset the code, try to start the car and I feel it slightly jump forward, engine does not start, then throws the warning code again. I did notice the traction battery is at 25%. I do this two more times trying to get the engine to start before I call the tow company. BTW, the car rolled easy, so I don't think its the MG2 is bad, although correct me if i'm wrong but doesn't Mg1 start the engine?
Oh, incidentally, also the ignition key does not release either. The key release solenoid is energized unless I unplug the 12v battery, then I can get my key out.

My wife said she had to slam on the brakes this morning to avoid someone pull out in front of her. She said the small yellow engine light came on right after.
Could it be low brake fluid? Not sure how that works.
It's a 2009.

I own a stock 2008 Prius.
My car didn't move for 1-2 months so I needed a boost this morning. I noticed there's the check engine light on and a red triangle.
Also, the car won't go on electric mode.

I have several problems with my 2008 Prius that I will try to list below and I have done much of mechanic work myself but now I am a little stuck with some of the codes that are coming up and with some of the problems my Prius is experiencing:
Here are the codes that were scanned when I took car to a local parts store:
Coolant Temperature Sensor Evaporated Emission System (Vacuum Leak)
p3193
Accelerator Pedal Position Sensor
Pump Control Circuit Low
" High
I replaced the thermostat and now I get the red light displays on the dash anytime I go over 45 and the thermostat light on the panel displays there is a problem. I think there might be air in the system. Should I have a mechanic bleed air out or is there an easy procedure that I can do on my own to fix this problem?
I have also purchased a water coolant valve and this will be my next part to replace at 106.00 dollars. I am not sure this will fix my problem with my heat but I do not want to replace the heater motor because those run 630 dollars each.
Being that it is winter I want to fix the problem so that we can drive the car with some heat and not get the red light to come on intermittently. How to get to the root of these problems listed above?

I have been having some hybrid battery issues. My prius is a 2006 with 198,000 miles. The original battery was replaced at around 120,000 with a junkyard battery. About a year later that battery gave up the ghost and I decided to rebuild that battery. So far that has worked quite well until recently.
My troubles started a couple weeks ago when I got the Red triangle and all the dash lights and the hybrid system icon on the MFD. Naturally I thought it was the battery again. Took it out and checked the voltages of the modules. All the modules where within tolerances. I grabbed a OBDII scanner and checked the code. It was telling me that the Hybrid current sensor was bad. I changed that out with the wiring harness from the old battery.
That lasted for a few days before the red triangle came back. I checked the code and it was indicating one of the blocks was bad. I think P3019. So I took the battery back out and replaced that block with other modules. Almost instantaneously the red triangle came back with two more bad blocks. I think it was P3012 and P3022. So I took the battery out once more and tested all the voltages of all the modules. Everything was 7.86-7.9v. So I decided to start the rebalance of the existing modules in hopes to find some bad modules.
I also bought a new 12v battery and installed that. I got everything back together and took it for a road test. It took about 30 mins before the triangle came back. I grabbed the codes and it was still indicating bad blocks. P3011 and P3018. I am a little at a loss.

2008 Prius with Nav/GPS system and 6-CD audio system. Around 30K miles, Bluetooth failed, and the Telephone Icon no longer appears on the Info Menu. Service Menu shows no version number for Bluetooth software, suggesting it somehow was deleted. Two local Toyota dealers don't know how to fix it. Toyota Customer Service gave wrong instructions: to eject the map data DVD and then reinsert it to reboot the system. That did not correct the problem because the map data DVD has only map data, not Bluetooth. Is there an internal hard drive on the center console unit that holds the software for Climate, Audio, Display, GPS, and Bluetooth? There must be. I need instructions on how to (a) reload the software, or (b) reboot the system to get software to reload. One local dealer said I had to replace the entire unit. That's like buying a new laptop because someone deleted Skype.
