Prius (2004-09) :: 2006 - Intermittent Red Triangle Of Death

Our '06 has 68K on it. Last weekend I changed the front bumper (just cracked from small accident last year) and changed the oil. Used Mobil 1 5/30 and a Fram Oil Filter.

After about 125 miles of driving intermittent Red T.O.D. Always when ICE is running.

Oil level is OK - not loosing any oil. Filter and bolt on the pan are fine - no leaks.

Prius (2004-09) :: 2007 - Intermittent Red Triangle Of Doom

PPH: (Possibly Pertinent History)

Original Hybrid battery failed April 2015.
1st rebuilt (Dorman) battery installed April 15 - Failed July 2015.
2nd rebuilt (Dorman) battery installed July 2015 - Failed October 2015.
3rd OEM (Toyota) battery installed October 2015.
Front end alignment (stay with me) May 2016.
Intermittent Red Triangle of Doom June 2016-present.
Installed Camber kit (yesterday...)

After I realized that I could duplicate the conditions for the triangle appearing/disappearing (brake/veer left to make it come on, accelerate/veer right to make it go away), I relaxed on the urgency of getting this addressed. After all - if the triangle goes away, there really isn't much of an enduring problem (I thought).

Brought the Prius to Legacy Toyota (Tallahassee, FL - BTW, I have only good things to say about this Toyota dealership) and the mechanic and I replicated the conditions while the Toyota diagnostic computer was attached.

Prius (2004-09) :: No Fault Code But Intermittent Red Triangle

Seems like issues with my 06 prius battery are back, however this time it is rather strange but very predictable. I cannot read any trouble code as the red triangle on the dash (and "problem" on the display) never stays on more than a few seconds (1-5 seconds at most).

At first it was doing this only after long downhill driving (like my 1.5 mile downhill street at 25 mph) - charging the battery and once getting to the last green bar I would get a Bip, red triangle and "problem" on the display. This has been going on for 4 weeks roughly.

But it's gradually getting worse, the same symptoms would appear after shorter downhill driving. And now it does almost every time I get the foot of the accelerator (assuming the car has decent momentum to regenerate).

I am guessing a module is starting to fail but last time I had a failed block, it didn't do that. One day I got the red triangle along with a bunch of other lights and that was it.

Prius (2004-09) :: Turn Off Intermittent Beeping When Red Triangle Lights Up?

I have a 2007 Prius 5 with 205,000 miles. Just recently, while Im driving the Red Triangle blinks on intermittently along with an annoying beeping. I took to dealer and they diagnosed error code C1300 which indicated that I needed a new "Brake actuator assembly with skid control ECU". I declined price tag because they said it's nothing critical (despite that it sounds rather important), and car will run fine without replacing this part. However, they said "nothing we can do about the intermittent red triangle and beeping".

Is this true? It's a very annoying noise. I know that it is possible to turn off the reverse beeping. Isn't there a fuse associated with "beeping" that could simply be disconnected?

Prius (2004-09) :: Intermittent No Start - Check Engine Light / VSC And Triangle On

So let's start with this. A week ago my dad went to start his car after going to the store. I wasn't there so can't say exactly what happened but when I got there the car would basically go into accessory mode with check engine light VSC and triangle on. Also displayed problem on the screen. I checked 12v battery with just the radio on (one button press with foot off brake) and it only showed 12.0 volts. So I hooked our jump box directly to the battery and it still wouldn't start. I scanned it for error codes and it showed nothing but I could erase them and the lights went off so probably codes from one of the hybrid computers I can't read but the car still wouldn't ready. I unhooked the 12v for about 30 second seconds and the car started fine without the jump box hooked up.

At this point I don't have any codes and with nothing to go off of I'm at a loss. We drive it 8 miles back to our shop and it drove normally with no errors. Once it was back in the shop after turning the car on and off 10 times or so still no errors. On the last time it was in ready mode and the errors came back on, still with no codes I could read. His 12v optima was still under warranty so we got it exchanged for free even though I was reluctant that it would fix the issue. Well a week went by and all seemed to be fine until yesterday.

My dad had left the car in ready mode for probably 20 minutes and when he got back in it all the lights were on. I will also add that the battery fan was operating normally and not screaming like if there was a traction battery issue. I changed one of the modules in his traction battery about 6 months ago when one failed. Without any codes I don't know where to start with this problem. 2005 with 170k miles....

Prius (2004-09) :: Intermittent Red Triangle Of Death After Making A Sharp Left Turn

I have a 2006 with 106K miles. Noticed after making a sharp left turn in a parking lot that the Red Triangle came on along with a beep and the message, "Problem" on the touch screen. Started happening more frequently either when the wheel is turning left or if I'm driving straight and the car drifts a little towards the left if I'm on the highway. Today it happened about 6 times. Warning goes off after a couple of seconds.

Prius (2004-09) :: Red Triangle / CEL On And Lost Power While Driving

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.

Prius (2004-09) :: All Dash Lights With Red Triangle Came On While Driving

2007 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.

Prius (2004-09) :: Red Triangle / Slow When Driving On Uphill

I'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 ?) ?

Ford Excursion :: Intermittent Shaking While Driving Down The Road

The Ex has started intermittent (less intermittent now) shaking while driving down the road. Not very noticeable at low speeds 20 or less. Idles smooth. Took it in and had tires checked, balanced, rotated, and aligned.

No difference. It was so bad my wife got pulled over by a police officer on the freeway here. He was extremely nice, looked under the car and suggested as possibilities. The locking Hubs on the front (4x4), U-Joints, Axle issue, Stuck in 4 wheel drive, or bad power steering pump.

Once she picked me up and we drove home from our dinner, I got pulled over. When it is in its violent shaking mode, it pulls to the right. when the shaking subsides (for an unknown reason) the pull to the right is gone. I do not notice anything that causes it to start or stop the shaking.

Prius (2004-09) :: Red Triangle Came On Dash And Lost All Driving Functions

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.

Prius (2004-09) :: Red Triangle Warning Indicator On When Driving On Highway

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] ....

Volkswagen - Cabrio :: Both Headlights Go Out While Driving At Night On A Curvy State Highway

My '98 Cabrio recently had the headlights both go out while driving at night on a curvy state highway. I pulled onto a side street and tried to figure out a way to be able to continue my drive home safely with lights. I found that by turning the ignition key to the right and jiggling the key I could get it to temporarily stay in a position to allow my lights to remain on.

In time, that solution was no longer an option and I discovered that by pulling the brights lever (it should be noted that it usually clicks into place) and holding it towards me, the lights would work, albeit on bright mode which tends to irritate fellow motorists. Strangely, the heater fan and wipers would only work while in this new found method of illuminated driving by releasing the brights switch and pulling it a second time towards me (remember, it doesn't lock into place as it should). How to repair this problem? It defies all logic as to why things on this car work or don't work.

Prius (2004-09) :: Red Triangle / Check Engine Lights Appeared When Driving On Freeway

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.

Prius (2004-09) :: Metal Cranking Noise When Driving On Dirt / Rough Road

I just got a 2007 Prius and using it mostly on a dirt/rough road. My problem is that there is a metal cranking noise coming from under car and trunk. This is nit happened when i drive on a good road.

I already asked the mechanic to check sway bar, shocks, struts, and brake. They said everything is okay except the front left strut boots which is already worn out. But the strut itself is still in good condition.

I'm OK everything except the noise. Already replaced new tires but it doesn't work....

Prius (2004-09) :: Clunking / Rattling On Driver Side While Driving Straight Over Imperfections In Road

So, fresh off the new brake actuator pump and new hybrid battery and a nice four hour drive yesterday and today i went over a small bump and started to get a loud clunk/rattle coming from the driver's side front wheel area.

It got worse as I drove home and even rattles going straight on a fairly flat road when i hit only minor imperfections. It sounds like something is loose. I cannot reproduce any noise bouncing the car or rocking it side to side.

Prior to this I would get a squeak/groan from the driver's side when I would go over speed bumps and similar large dips or rises, but that has been curiously quiet for awhile.

Prius (2004-09) :: 2007 - Intermittent Sound While Driving?

I am a relatively new owner of a 2007 Prius and am curious about a sound I hear quite often while driving.

The sound is similar to a cd changer changing disks my package doesn't have the disk changer). It seems to happen when braking but I haven't pinned it down to one catalyst.

It seems to be a normal sound and I am not worried about it since riding in my roommates '07 Prius and heard the same sound.
