View 9 RepliesI am just trying to find out if this means I need to have something checked like coolant hardware/fluid...
It is over 100 F these past several days and at 35 minutes just hopping off the freeway, and then again today, coming down a big hill at another part of the freeway, I noted that as I quickly had to brake the system made the computer noise (same as when I switch from the power view to the trip view), red triangle comes on, no other indicators. The first time it happened I was back on the throttle almost right away and red triangle went back off.
Everything fine. Same today but it was on until I was back on the throttle at the bottom of the hill...
My '04 with 193,000 miles has in the last week displayed the above trio of warnings (the word "PROBLEM" appears in the MFD and disappears instantly) plus the infamous Red Triangle of Death appears and there is an audible chime, 7 times; 4 when changing lanes and 3 at random times. The trio of warnings come on for literally 1 to 1.5 seconds and then go away, and there is nothing apparently wrong with the car, the handling, the performance, etc...it continues driving as sweetly as ever. Nothing. No engine warning light comes on (if there is such a thing), or anything else. I have new tires, the tires are all properly inflated, so it isn't the tires triggering the traction control warning.
View 12 RepliesWhen I tried to start my 2006 Prius ,it wouldn't start and this message appears with the red triangle "there is a problem with the transmission "p" lock mechanism. Park your car on a flat surface and fully apply the parking brake.
It is at a parking lot now because I couldn't start it!
My partner's Prius is bring up the red warning triangle. She had a system diagnostic carried out, which brought up these two faults:
C1241 Low Battery Positive Voltage
C1300 ABU ECU Malfunction
The faults were reset, but it was only a short matter of time, before the red triangle appeared. My partner tells me this tends to happen more frequently when she is steering left and in colder weather.
She was advised the ABS ECU will need to replaced (it does says "new actuator" on the paperwork)
I am going to remove LED headlights & do a full HID retro.
Only problem is that the car has a system check & throws a flashing yellow triangle. How to trick the system?
There are 6 wires on the LED headlight harness.
I have 2005 Prius with 110k. Yesterday, red triangle and check engine light came on and I lost power while driving...SCARY. Took it by dealership. They called this am and said it needed a new HV-ECU and that would cost $800. The error codes they gave me were P0A78 and P0A94. Anything else I should ask them to look at? I'm wondering if the HV ECU is something I could buy used and install myself? I'm not a mechanic but am comfortable with most DIY projects.
View 10 Replies2007 Prius 215,000 miles. Car has been a champ for the almost 2 years I've owned it, buying it with 150K miles. No real troubles and I've been driving it constantly as you can tell. Had an extended warranty repair done back in the winter when dash lights went out completely yet car would still start & run. Replaced 12V battery back them trying to diagnose trouble and it was original battery anyway. Daughter was driving when almost all dash lights came on including the red triangle. She came back home, turned it off. Next start was just red triangle and check engine light with red car on center display. Now it's just the check engine light and red car after sitting for an hour. I plan to take it in to get check engine light checked out.
View 4 RepliesI've bought a second handed European Prius 2en Gen from year 2006, the car is wonderful and I simply love it ! I wouldn't change it for anything, but yet I have some problems with it.
When I start the car I get the Red Triangle on the front panel, and exclamation symbol, a VSC symbol and an engine (?) symbol on. On the Display I always have a black bar on the top with a car and an exclamation point on it. Both can be seen int the pictures below....
At this point the car runs normally, the only things I notice are :
1 - When I stop the car (without shutting him down) I notice that the consumption of fuel is at 99.9/L because it is charging the battery, which is already full.
2 - The back-right ventilation fan of the car (on the passenger seat) is ON even when the Air Conditioner is OFF.
After a few miles (I don't know exactly when it happens, sometimes it happens when stopped, sometimes when on the road), the car beeps and then it shows a, on the same black bar on the display, a message saying "Problem", after a few seconds I get a Battery symbol on the right of the car with an exclamation point symbol.
At this point the car starts having the following problems :
1 - The motor begins to speed like if I was at full speed on the highway.
2 - I simply can't do an uphill, the car won't pass the 20Km/h speed, if I gain balance before arriving at the uphill, it will start losing speed until reaching the 18-20Km/h.
At this point I really don't know how to solve this. I only know that, the Toyota Representative here where I live (in Portugal), ask me for 2,975Euros (almost 3,263USD) saying that it is a problem in the Hybrid System. But yet it seems strange because from what I know, if the Hybrid System was compromised, the car wouldn't start at all.
Does changing the 12V Battery on the back would solve this (even knowing that the Display shows a fully charged battery ?) ?
I was at an intersection and red triangle came on dash and lost all driving functions. Had to turn power off, then turn back on. Was able to drive 100 yards to a parking spot, but it went out again. Reset car again, then it happened 4 more times within 2 miles while driving. Had to call tow truck. Just kept shutting itself down. How to fix this. See picture below for the message I got when it happened. This is the first time my car has malfunctioned like this. I think maybe its throwing itself into park or neutral (judging by the P-lock message below) and cuts all throttle control to car. Has 105,000 miles on it.
View 19 RepliesStrange thing on my 2006. Driving on curvy road, would occasionally get just the "Red Triangle" exclamation point (for a second or so) -- and also the word "Problem." would flash up on the display.
No permanent check engine light or other icons lighting up. Still getting 40MPH, everything seems to be driving right. Have 135K on the odometer.
Question - does that triangle thing store codes that can be read by an OBDII reader each time it flashes -- or does the check engine light need to be on?
Second Question - Any clue what the word "Problem." with no description could refer to? It goes away at the same time the red triangle goes away.
I was on the highway yesterday when the red triangle went off and the screen said Problem. I babied my 2008 Prius to the dealer. They said the 12v battery was bad. I should have just gotten the yellow top in last week like I wanted but oh well. Here is the problem, today it did it again. It first happened at 70 mph but today it did it first at 15 mph then pretty much stayed on until I did not accelerate for a while. No noticeable performance issues, just the warning indicator. I did notice the noises after shutdown are sounding different than before last week. I also put a code reader on it both without running and on a test drive and no codes showed. What is going on?
More info: Just hit 100,250 miles. Purchased on March 17, 2008. Went in last week before the 100,000 miles for a check up and ended up with $1,000 for a coolant pump (both now, other coolant pump was replaced within the last 6 months). Also got: break fluid, belt, break alignment, oil change, tires (this I was expecting hardly passed state inspection in March), possibly something else.
I have been doing the oil changes since 15,000 miles, filters, pcv (or pvc whichever), all normal items. Problem free until I have them do a check now issues. So to recap non normal items done: blower motor in 2009, radio replacement in 2008, coolant pump in Mayish, other coolant pump and 12 v battery last week. Read more : [URL] ....
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.
View 19 RepliesI have a 2008 Prius with 111,000 miles on it and lately, I hear a loud chirping, whining sound that is louder under acceleration and seems to vary only according to acceleration or deceleration. Acceleration makes a louder sound. The noise does not occur when vehicle is cold and first driven. It's only after it's driven for awhile and things are warmed up but then again, it doesn't always do it even though it's warmed up. Not sure I could reproduce the sound if I brought it to a dealer for service. When the noise does start up, it's very apparent and loud and then, after awhile, it goes away temporarily only to start up again.
View 5 RepliesOur 2010 Prius makes a loud metallic slapping sound whenever we drive over the lane marking reflectors on the roads.
Audio recording included....
I have an '04 Suzuki Aerio, and there is a loud popping or knocking sound coming from the front of the car when I drive it. I don't seem to hear it when the car is inert (i.e. idling or traveling in a straight at a constant speed). I hear it intermittently when I accelerate/decelerate or turn. I hear it in drive and reverse. The strange thing is that it seems to go away completely when it is raining, and then come back when it stops raining and things dry out. It has been happening for a month or two. I think it has been gradually getting a bit louder. What could cause this?
View 6 RepliesOn a recent road trip, my 2009 Prius began making a loud dragging sound. Pulled into a car dealer at the freeway exit (Mazda) and found the black plastic shield on the front bumper had cracked down the middle and was dragging. I had them remove it to finish my drive home; my question now is, what should be considered a fair price for having this replaced? Last fall, I had a minor accident and had to have body work done on the hood and front fender; should I have the body shop that I used check it out, or stick with the dealer? I'm wondering if the shield might have cracked in the accident and was overlooked. As a single 50-something female, I just want to know what a repair like this might run, so I don't get taken for a ride.
View 7 RepliesI have a 2nd generation prius and up now no problems but today my car continously makes a pretty loud buzzing sound if the car is on or off. No lights are on other than the maintenance reminder light as I currently have 57000 and waiting a little longer before I bring it in for the 60,000 check up.
View 4 RepliesMy car have sound like motor running during I drive while i turn off the radio and I try to get where is the sound come from it seem like near driver seat, by the ways what is that sound ? it happen around 2 second only and after a while it happen again....
View 2 RepliesMy 2007 Prius II is starting to sound like a little roadster - when I was driving on the freeway behind a large car I thought it was them, or just hoped we braked and hit the accelerator at the same time thinking it couldn't be my car.
Only after that car left did I realize it really was my usually-ninja car making the loud purrs. It cruises quietly and the sound goes away, it's hitting the gas that makes it loud. The mileage is the same, it feels the same, it's just loud now.
My 2006 Prius with 206k miles is making a loud buzzing/grumbling noise when I press down the brake and periodically when parked. It's coming from the general area of the brake pedal, under the steering wheel. See video for a recording of the sound:
