Driving home early from work today, moments after leaving the parking lot the VSC warning light illuminated. Followed by ABS and Power steering lights a few seconds later.
Car drove normally. Systems seemed healthy.
I quickly pulled over, took this picture, and then power cycled the car. The warning lights turned [off] and stayed off for remainder of drive home (~30 min).
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.
View 19 RepliesI recently purchased a 2001 Prius from a state fleet auction. The car has 121,000 miles and was in the non-running part of the auction. It had been sitting at least four months. I decided to give it a go since it looked to be in decent condition.
It did not start because of a dead 12v battery. I bought a replacement battery, but it still did not start. The screen showed ~ 1/8 hybrid battery. The warning lights illuminated and it was never ready. I plugged in my code scanner and a P3030 code came up.
I got it towed home and started working on it. The P3030 code signifies a high voltage line snapped .
This afternoon, after driving about 150 miles, I came home and shut off my 2001 Prius. It was sitting for about 20 minutes before I turned it back on to drive off. Almost immediately, the hybrid warning light came on on the MFD, the red exclamation mark light illuminated, as well as the check engine light, and the motor shut off. I popped the hood, and could hear a high pitched squeal coming from near the inverter. I called my dealer to ask the service department what I should do, and they just told me to bring it in and they will take a look at it. I live over an hour away, so I don't want to bring it there if I can avoid it. I then shut it off and let it sit for a few hours.
After reading about the possibility of the auxiliary battery being bad, I went and turned the Prius on, and then shut it off several times to reset the hybrid warning light (I had to do so in order to access the aux battery information through the MFD). It turned on without incident, and shut off fine, and after being reset the hybrid warning light shut off, as well as the red triangle light. Then, I went through the process of pulling up the battery voltage information through the MFD.
With the car off, and the lights and fans off, the battery voltage read about 10.0-10.5 V. With the lights and fan on, the voltage dropped to about 9.5 V. After getting those readings, I drove it down the road a little ways, just going about 20 mph. It seemed to work fine. The check engine light is still illuminated. With the motor running, the voltage reading was 13.2 V, and then when I got back from my test drive and shut it off, the voltage hovered at 10.6 V with the lights and fan on.
My Prius is 07 with 146k in southern California, for two days every morning I took a short trip to a store then when driving back home the prius battery lost bars fast and I lost power with all sorts of warning lights. Then I drive off with no problems for the entire day. I disconnected the aux battery and that reset the Error codes, I checked the inverter pump and works properly, I checked the aux battery and shows 12v when off and 13.9v -14v when on. This happens every morning so I suspect it's the aux battery. 3months ago my dash lights went out and rebooted the car with no problems.
View 5 Replies199k on my prius. I'm driving 65 mph and bam! All warning lights come on, PROBLEM, comes up on the mfd, and the mfd had a funky little broken cat symbol light in the top left corner.
I lose engine power and coast to a stop. As I'm coasting the speed display stops showing my speed... even though the rest of the gouges are lit on the display. While parked I realize I have very little 12v battery juice....
With a jumper pack on the front terminals I get the cat home. I ser on the display the my hv battery is stuck at one bar.
At home I charge the 12v battery and get the hv battery fully charged by holding the gas down in drive with foot on the brake. My Toyota mechanic told me to do that. All warning lights go away. I leave a jumper pack on the battery in the rear and take for another test drive. Car is better but still sluggish... Try to get it up to 50 mph and bam! again all warning lights return.
So I get the car to toyota dealer and and my guy reads the codes and tells me every ecu is showing codes abs recommends 12v battery replacement. He clears the codes. So I buy a brand new battery and after installing it all warning lights return on test ride. Car won't do over 50 mph and is def still a mess.....
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.
I have a 2009 Prius with about 72k miles on it. Today, after about 45 minutes of highway driving, these lights all came on: master warning, the "check" indicator, VSC, the circle brake indicator, and the hybrid system warning on the multifunctional display.

View 10 Replies2009 Mazda 3 Since a nasty cold snap in Northeast, instrument panel has gone crazy. The meter showing RPM's works but 0 on the speedometer- dead. Gauges have been all on for a couple weeks. Just noticed now the power steering is gone. All lights seem to work normally and heat/defrost works. Radio works. Haven't noticed if odometer is working or not.
View 3 RepliesI had just picked my kid up from school, as I turn out of the parking lot my A/C stops blowing cool air, I check the A/C screen and it still says it's set on High with temp at 68. However, it is blowing very low with warm air. Seconds later the dash lights up with numerous warning lights. I'm on the highway and I'm able to gather speed, but each time I do I hear the engine revving like crazy. We only live a few miles from the school so I am able to make it home. Once home, I turn off the car and turn it back on. The only warning lights displayed now are the red triangle and the yellow check engine light. I turn the car off, pop the hood, I check the belt and it was fine. I checked the oil and it seemed fine. I check the coolant overflow and it was empty.
View 15 RepliesA few days ago I noticed when I started the car that both the HV/EV and ECO mode lights were illuminated. What does that mean?
View 8 RepliesWhen I turned my Prius on today, the following warning lights remained on:
red "BRAKE"
yellow "ABS"
yellow "VSC"
yellow exclamation mark inside a circle inside parentheses.
It drives fine. After driving it a bit I tried turning the car off and back on a few times. The lights still remain on.
Mine did. I was driving on the highway and pretty much every warning light went off. It was like the space shuttle crashing back to Earth. Freaked me out. Cruise control stopped working also. But I was able to get home safely.
So first, I tried AAA just to see if the guy would know something, but it was way over his head. He did notice my aux battery was failing, but not much else. Then I found a service online that comes to your place to do the work, and they sent a guy out on a Saturday and he read the codes, and did a full visual inspection, and yes, something was up with the cooling system. He suggested I have the dealer look at it because flushing the system is VERY important apparently. Should be done every 50,000 miles.
I was so worried it was the hybrid battery; we all know what that means! So I had the car towed to the dealer (don't drive if your Master/Hybrid light comes on!) and they said, indeed, the pump was gone. And, of course, they found a number of other things included the dying aux battery. It took them 4 days to get the damn part in stock. At least they covered the car rental for me.
The other night, went to start the prius and nothing happened except all the warning lights came on! So took the foot off the brake pedal and sat there for a minute trying to figure out. What the heck happened?? Tried a couple more times and then suddenly it was fine and it started! Now I have to mention that the outside temp was around 16*,,, not sure if that could have caused this strange reaction?

View 11 RepliesI bought a toyota prius 2008 few weeks back. ave done only 2500 km. Today I received few warning lights on the dash of my car.
View 19 RepliesTwo days ago the first sign of a problem was the AC going out, followed by the red warning triangle and check engine lights coming on about 10 minutes later. Checked coolant and topped oil off (it is due for an oil change, btw) and drove about 20 miles home, no problems despite warning lights. Even the AC started working again. A little while after getting home, I started it up......no warning lights. I thought all was good.
Yesterday, no issues. Didn't drive more than about 15 miles though.
Today, took roughly a 25 mile roundtrip with no problems. Made the exact same roundtrip about 2 hours later and the red warning, VSC, brake system and check engine lights all came on (see pic) about 10 miles into the trip. I immediately turned AC off to remove that stress. No changes in car's behavior, however. Made it back home, turned car off and waited about 20 minutes. Turned it back on and only the red warning and check engine lights came on. 2 hours later....same two lights are still on.
My wife has a 2007 Prius with approx. 110k miles. We installed a new 12V battery approx. 1 1/2 year ago at 81k miles. A few months ago (Mar/Apr), her dash would randomly display the warning lights shown in the 1st image: Brake System, ABS, and VSC (the TPMS light is always on due to faulty tire pressure sensors and appears unrelated).
The car seemed to be driving normally with no abnormal behavior. Whenever this happened, my wife would pull over, turn off the car, and restart - at which points all the warning lights would disappear.
Even though our 12V battery is relatively new, I did check the voltage of that battery using the MFD's on-board diagnostic screens as explained by other posts on this board. Voltage was within the normal range with the HID lights both on and off.
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.
It has been cold recently (out of the past week, highs in 20's or lower). This hasn't been as much of an issue before, but in the past week I have had the red triangle of death, brake warning light, check engine light, and VSC light all come on at the same time, three separate times. Also, the display screen shows a red outline of a car with "!" through it. Each time this has happened, the lights didn't come on as soon as the car was "Ready" but only after the gas engine was running for a minute or two.
The first time the lights came on, I was driving back from class, but after I got back to my house I did some internet research and saw it may be a low oil indicator. Checked the oil, it was almost at the bottom mark on the dipstick, and it had been over 10,000 miles since the last one (oops! we don't normally do that). After reading some stories online, I took it in to get an oil change, and the lights went off for a couple days. Second time the lights came on, I checked the oil level, it was definitely over-filled, so I took it back to Walmart and had them redo the oil so that it was at the right level. I checked the oil level before leaving the parking lot that time and it was at the top mark on the dipstick. Again, all the lights were off for a couple days.
Today, I drove my car for about an hour in the morning (temperature was around upper teens, wind chill below 10) and had no problems. Then, this evening I turn the car on and start driving out of the parking lot when the car beeps at me and flashes all of the warning lights again. I drove back to my house and it is now sitting in the driveway. I am not planning on driving it until I can have a car mechanic friend take a look at it on Tuesday, but he doesn't know anything about the hybrid system/battery.
My wife and I have also noticed that since the weather has been colder, the hybrid battery (shown on the "Energy" screen when driving) seems to be charging and discharging much faster than normal. I haven't seen it at only 1 bar or full of green bars more than a couple times in the 2.5ish years we have owned the car, but in the past two weeks it has happened 5-10 times (estimated). I am not sure if this is due to the weather, or if it could indicate a problem with the (hybrid?) battery. For obvious reasons, this makes us nervous :/
As a side note, I changed the transmission fluid sometime in December, so I was wondering if possibly I didn't put enough fluid back in. I have checked the diagnostic screen and found some codes, but most of them seem to relate to the audio, which doesn't concern me as much as the code that seems to indicate the transmission, which is why I mention the change I did a while back. I just don't know why it wouldn't have shown up until now. I'll attach some pictures I took tonight of the codes and lights.
Also, the battery is a couple years old, but after sitting for a couple hours the battery was reading 12.1 V according to the diagnostic screen, so I don't think that is the issue. We haven't had any trouble getting the car to start, and once it is running it still seems to drive normally with the warning lights on. What these codes mean, and a possible cause for the warning lights?
