It was driving me crazy that the red triangle warning light (master warning light) flashed for only a split second, once per day, two days in a row.
I drive 100 miles per day. My 2004 Prius has 136K miles.
It turned out to be low motor oil level, 1.75 quarts low.
My car is burning about one quart every 5K miles which probably is within the normal range for a 136K car.
I most recently drove my 2006 Prius around on Saturday Feb. 1, with no problems at all. I went out of town for a couple of days, and returned this afternoon to a car that will not start. I stepped on the brake, pushed Power, and things lit up, the "Ready" light flashed a few times but then went off. Power button light stayed orange.
Several warning lights on dash stayed on (!)/ABS/VSC/traction control, and a message came on the screen saying something about a problem with "P" parking, and that it should be parked level and the parking brake applied. It is sitting level with the parking brake applied already. Also, the door ajar warning light and beep start as soon as you open the car door to get in.
I'm thinking from what I've read that my 12v battery has died/is dying. I'm the original owner, bought car in March 2006, and it has just under 61,000 miles on it.
In my one-owner purchased-new 2005 Prius w/ 74K miles and w/ no maintenance/accident history other than doing all scheduled maintenances at Toyota Dealers along w/ recalls applicable at each time (other than we had Toyota replace the 12V battery last year just because I knew it would die at some point anyway and I don't like pushing my luck; I'm not 100% certain if there's been a recall on any water pump for this car and if so, don't believe the dealer has mentioned it), I have the following indicators which appeared all at once while I was driving along at around 45 MPH in no unusual circumstances (80F, dry afternoon, about 30 minutes into a trip of mixed speeds, no loads in the vehicle, no effect on the car while driving):
From Left to Right on the display:
1) Red Triangle - Master Warning Light
2) Orange (Symbol)CHECK - Malfunction Indicator Lamp
3) Orange (!) - Brake Warning Light (but it didn't highlight the word 'Brake' in red)
4) Orange VSC - Vehicle Stability Control Warning Light
On the Screen:
Orange Car w/ the ! symbol - Hybrid System Warning Light
We immediately aimed for the house (about 5 miles away); the car drove perfectly fine, with the engine stopping and starting at lights as needed, with speeds going from the 55MPH we were traveling at the time of the alarms down to 0 and back up thru 35/45 MPH and such per normal off-interstate driving. The battery currently shows all the blue bars, and the engine and hybrid systems showed charge/discharge as usual as we drove. There was no discernible change in the driving reaction of the car to brake, steering, accelerator, etc.
My tire pressure light flashed for a while and then remained lit for several minutes during a several-hundred-mile roadtrip a few days ago. The vehicle did not pull, drag, or show any sign of tire problems, and when I checked the pressure on all four tires the next morning they were fine.
View 13 RepliesWhile driving tonight I was making a right turn and I heard two short beeps and my interior light flashed on and off two times. This happened three more times after stopping and when I put my foot on the gas again the interior light came on and then off again, no flashing or no beeps.
I just hit my 16,000 mile mark on my 2014 Prius C two.
Pulling into the gym tonight the old red triangle flashed for a second and the car sort of hesitated. But after that it drove ok the remaining 100 feet to the parking space. When I left the it started ok and after about a few minutes and a mile down the road the screen displayed "Problem" at the top and I noticed the lights and dash lights were getting a bit dim but came back right away when I started moving.
View 19 RepliesThis is the third time I am having this issue, previously once it was close to service so dealer just added the oil and few months ago it happened again and I did the 1200 mile test where the dealer measures the burn rate, nothing came out of that. Finally I had it last few days, it was flashing intermittently and I took it to the dealer and they added 2.7 quarts of oil and while I have 2500 more miles to go for the scheduled service. Looks like my engine is burning oil. I don't have any visible leakages as my garage is clean. I will update after my second 1200 mile test. However I suspect nothing will come out it as I have few long drives planned and 1200 milestone will come up fast. I am having this issue if the time between the oil changes is more than 3 or 4 months. My car is 2007 LS 460L.
View 7 RepliesFlashed to 1.5 v8.1 91 and had no issues with flash. Then tried to start car and all warning lights on and no start. Flashed back to Performance Pack stock version and again no issues with flash, but same problem, warning lights and dead car. Disconnected battery and reconnected without any change.
View 21 RepliesWe recently purchased a used 2006 Prius. The vehicle has approximately 74K on it now. Well the other day my wife went to leave work and pressed the power button while pressing the brake pedal, and the Master Warning Light and brake warning light both came on. The car would not allow her to shift the car so she tried to turn it off and it wouldn't do that either. After about 5 minutes she finally got the car to turn off, and when she restarted the sequence everything went back to normal and she drove home fine.
We called 2 dealers and they both seem to be confused by the symptoms, but one thought that maybe the battery was old on the transmitter. So thinking that might make sense I replaced the battery with a new one.
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.
I have a 2015 Hyundai Accent, and haven't had any problems with it whatsoever until this past weekend. I was driving with my Mom, driving her around to do errands, when all of the warning lights on the instrument panel flashed and then disappeared. My trip indicator also reset, even though I hadn't been using it at the time - I usually keep that button on the gas mile screen (the one that tells you how many miles you have left until you need to get gas). But when the lights flashed, the gas mile screen disappeared and reset to the first screen (the one for the trip indicator, which had gone back to zero abruptly). I'm not sure why this has happened. The car didn't stop or anything like that. I was actively going down the road at the time, going a decent speed. The only thing out of the ordinary was that there was a traffic helicopter above us (this was in an area that tracks speed by air radar), and I wonder if this happened because the helicopter hit us with the radar?
View 7 RepliesUnfortunately the above message flashed up on my dashboard last night, and it has re-appeared first thing this morning. The first thing it switched off was my air con, also I notice that the battery meter now barely gets above 12, prior to this message it would go up to just under 14 once the engine had started. I have a 2004 3.2 v6 and, as a preventative measure, I had a new battery fitted about 4 months ago.
View 11 RepliesWhile highway driving the other day the Flat Tire Warning flashed and beeped for no reason. It flashed on and off for about an hour. Is this a faulty pressure sensor?
View 3 RepliesI was driving down the road and the VSC warning light came on with the check engine light... What could be wrong should I have it tow to the dealer!
View 4 RepliesThe red triangle warning light on our 2004 came on and went away again It has 100k miles If I take it to the dealer can they pull some codes and figure out why it turned on We have to drive the car to 600 miles for the upcoming weekend and I don't want to be stranded on the side of the road The car has 103,000 miles We just replaced the 12v battery so I know that is OK
I also saw the following things to check. Is there anything else we should check?
1 - Are any warning lights on besides the red triangle? For example, the red BRAKE light, the amber ABS and VSC lights, or the amber circular icon?
2 - Did you check the brake fluid level? If low, buy a new container of DOT3 brake fluid and replenish as needed This fluid will dissolve paint, so do not spill it
3 - While you are at it, check the radiator and inverter coolant levels by looking at the translucent reservoirs behind the radiator and next to the inverter If low, fill with Toyota Super Long Life Coolant
I was driving earlier today and it flashed twice (about a second and a half each), and then didn't see it again for a few hours. I was going about 40 MPH at the time.
I was driving somewhere else today and when I got to the 70MPH mark (really, between 60-70), it objectively increased in frequency. I searched google and these forums, and the closest thread I can find that shares my ailments was this one:
After 10 minutes running errands in stop and go traffic, I noticed the VSC warning light. It was a hot and humid day (mid-80's). Made it home and was unable to open my garage door with the mirror that is equipped with an automated door opener. I turned the car off so I could open the garage, and when I tried to start my car again using my smart key, it would not start. I put the key in the key slot and was able to start the car, but the smart key, radio, windows and automatic door lock would not work.
Mileage is just under 25K.
So the other day my girlfriend got in her car and it had the master warning light on. we took it to the dealer and now they are saying it is something with the transmission and it would be cheaper to just install a new one. Another thing is how could it be the transmission if i drove it over to the dealer and head no problem with the gears changing, but he also said something about a voltage leak.
View 2 RepliesI nearly killed my 12v battery this week when I left my dome light on in the Airport parking lot. When I got back to the car I was able to pop the hatchback, but there wasn't enough juice to start her up. I was able to get a booster pack jump and it looked like everything was fine (didn't even lose the radio presets on the aftermarket deck). I had a long ride home to charge the 12v battery up. I changed out to the Optima yellow-top a couple years ago, so I'm not too worried about the battery being crippled. I've gone into the onboard signal menu and the battery voltage is well within spec idle and under load after a few hours of driving recharge.
Low and behold, the next day the VSC warning light came on and won't go off. I am NOT getting the brake (!), red triangle, or ABS warning light as others have received with 12v battery issues. I put on the OBC scanner and pulled no issues. I jumpered pin 13 TC and 4 Gnd on the interface to get the flash codes and sure enough, I'm getting a 34 code on the VSC system. I have been unable to clear the code via tapping the brakes.
What a VSC 34 is and how to clear it?
On my gf's 09 Prius the warning button doesn't light up during the night with the headlights on. You can't see it. Is this normal?
View 2 RepliesRecently I had a warning light accompanied by the ICE shutting down. P0121. As the repair, the throttle body was cleaned.
A week or two later, while in Park with the parking brake engaged, I got another warning light along with some text on the display, something about parking brake. I didn't completely absorb the message before powering off, waiting, then powering on. No more warning light.
