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) :: No Power / Low Battery On MFD / Red Triangle Light
I changed my oil, oil filter, air filter at 90k for a trip to Miami this past weekend. Uneventful on the way up. On the way back, stopped and did some shopping before hitting alligator alley to come back home. As I got on the alley after paying the new $3 toll my 05 prius with 90k miles on it would not go over 65 with my foot on the floor and the battery on the mfd was in the pink. So I drove to the nearest exit, checked the fluids etc, all good. Got back on same thing so I put on hazards and stayed on until i could get off on a much slower road. I was going about 55-60 and it would go no faster.
As I got to a place I pulled over DC'ed the negative battery cable and let it sit for a half hour. I then attempted to get going and it seemed to be running fine until I attempted to pass a car and the car seemed to lock up and lose all power, check engine light came on and the red triangle light came on. I pulled over and let it sit again. I then got it to a gas station with the check engine light on. I put a few gallons gas on and tried to limp it home. It made it home and the battery seemed to recharge back to all the blue it can get to, but has yet to hit the green.
Prius (2004-09) :: RED Triangle Light On - Power Steering Doesn't Work
My red triangle light came on! and the PS light came on the square screen and my power steering is in the dumps (doesn't work).
Where would be the first place to check? could it possibly be the accessory belt that came off/broke? is it hard to access/replace that?
Prius (2001-03) :: Won't Start / Getting CEL But No Triangle?
My 2001 won't start. When the key is turned, the system starts up and the hybrid system initializes, there are 3 clicks in the dash, and the check engine light stays on, without the engine even turning over. I had a mechanic look at it cursorily and he said it looks like the hybrid system is fine, the signal to start the engine isn't resulting in the engine starting. He said it was probably the starter or a fuse to the starter, but the gen 1 Prius doesn't have a starter, so I don't know that I can trust his diagnosis.
The 12v battery is brand new (3 months old) and is an aftermarket deep cycle battery. Also, it has been very cold here. The triangle of death doesn't appear, so I am hoping that it isn't something in the hybrid system. It did this off and on before it stopped starting at all. I was also getting the turtle intermittently when it was giving me occasional problems. Turning the car off and on a couple times usually made this go away. The car has 154k on it. I am thinking it might be the ignition starter switch, but I'm not sure.
Prius (2004-09) :: Master Warning Light / Red Triangle Exclamation Point And Check Engine Light Came On
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.
Prius (2010-12) :: ESC Light And Caution Triangle Comes On Then Go Off Before Ready Light Lit Up
Just bought a 2011 Prius and I love it. When I push the power button to turn it on, the ESC light comes on along with the caution triangle light for about 3 seconds then both go off and the "ready" light comes on. is this a normal occurrence?

This morning I pressed Start and all I got was the Red Triangle. This has happened a few times in the last month, but it always started up right after that. Today nothing. Well, a couple other attempts got some of the display to come up, but really nothing. The doors, including the trunk, won't unlock.
Since it has over 119K miles I think it might be the Aux battery, but it ain't easy to get to as I have to enter the trunk via the passenger compartment.
Prius (2004-09) :: Won't Start - Red Triangle Message
I purchased a 2009 Prius last year in the US and then got stationed in the UK. I had my car shipped Aug/Sept 2013 to the UK. Up until now the car has run great with no problems. Three weeks ago a red triangle with the message "there is a problem with the transmission "p" lock mechanism. Park your car on a flat surface and fully apply the parking break" appeared.
A week later the car wouldn't start. After reading several forums and posts I checked the battery and it was indeed low. It looked like the original battery and was reading 9.3V. I had the car jumped, drove to the local Toyota dealership, and bought a new battery. After installing the new battery the car ran fine with no issues.
Five days ago (Friday) the car wouldn't start in the morning, but all of the lights worked. Then about 3 hours later the car stared and ran fine all day.
Prius (2004-09) :: Red Warning Triangle For Few Seconds When First Start The Car
About a month ago my 2009 Prius - 35500 miles - started acting up intermittently. When I first start the car I am getting a red warning triangle for just a few seconds and I feel/hear a soft thump under my foot that is on the brake pedal, there is a few second pause - the warning light goes away and the car starts just fine. This does not usually recur until the car has shut off for a few hours or so. I have had the car to my Toyota dealer twice and they could not reproduce the warning light even after it had been sitting all nite. That was about a month ago - and the problem has been very intermittent. Then yesterday we had a pretty cool morning and when I started the car I got the red warning triangle and a Warning on my screen -- something to the effect that "There is a Park and Transmission Lock" - I turned the car off and started again almost immediately - no warning triangle - no warning message. It happened again once this morning.

Wife calls says car barely goes, triangle shaped warn lite with ECM in middle is on. Took car to dealer, SA says ECT leaked coolant into harness and shorted out ECM. Car is a 02 with 63K. Is this a common problem? Service Advisor doesn't seem to have a clue.

The car is a 2005 Prius II hatchback @ 70,000 miles. I like my local garage and they have a good reputation but bad things keep happening. I'm ready to lose my temper but I don't want to. Here's the summary:

Gen 3 Prius (Audio/Electronics) :: Yellow Triangle Shows Up When Start The Car
I tried installing a backup camera today. big mistake. When I start the car the yellow triangle shows up. and warning says check hybrid system. I try and put the car in reverse and I hear a snap, it slips to neutral and a warning appears that says put into P position. The only wire I tapped into was the red reverse light camera. I even tried undoing the install and I get the same messages.
View 18 RepliesPrius (2004-09) :: Red Triangle Is Displayed, Along With CEL On Dash After Jump Start
Recently, my Prius hasn't been getting much use, so the 12v battery drained. The car worked ok after I gave it a jump. But, because I don't drive the car very much, the battery drained again, maybe completely.
When I jumped it again, the car ran ok, but the red triangle is displayed, along with the check engine light on the dash, and a red car icon on the MFD. The car drives, but the lights are on.
Before replacing the battery, should I take any steps?
Prius (2001-03) :: Shut Down Shortly After Start Up Red Triangle Flashing?
I have a 2001 Prius with 204K miles. On cold mornings when I start the car first time, within a minute it shuts down with red triangle flashing. After resetting it, car works fine all day without any problem.
View 8 RepliesPrius (Gen 2) :: 2004 - Red Triangle Warning Light Came On And Went Away?
The 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
Prius (Gen 2) :: Big Red Triangle And Hybrid Warning Light
The last few weeks I've been noticing that, upon start, the hybrid battery is showing at 1 line. It's been really hot in SO cal and the air con has been blasting, so I've been letting it charge up a bit before driving. Once I'm on the road, the battery charges fine and seems to hold a charge.
View 10 RepliesPrius (Gen 1) :: 2001 PS Light Along With The Triangle Came On While Driving
A few days ago the PS light along with the Triangle came on while my partner was driving. We've been noticing a slight shimmy with the steering wheel while backing up only, until this issue came up. Otherwise we've seen no other issues with the steering while driving.
When we took the car, which has 167,000 miles on it, to Toyota, we walked away with a $3,770.00 estimate to replace the power steering system.
Some of you noted earlier that you continued to drive your cars when you noticed the PS having issues. One guy said he did it for 30K after the first warning. I'm wondering, how did you get the PS symbol to go away? (The dealer reset ours, I'm wondering about if it comes back.) Are you still driving with the issue?
