I just tried to start my Prius this morning and nothing happened except a quick flashing red indicator light which looks like a lock symbol. Not sure what's going on.
View 11 RepliesI have a 2005 Prius with 240,000 miles. About 4 months ago the triangle warning symbol appeared. A friend and I decided to pull the big battery out of the car and find the bad cells. We did that, replace two and the car worked fine for 4 months. The triangle warning has returned. We have done several things but the triangle remains. We pulled the big battery out and checked all of the cells. We replaced one that was probably OK. The latest reading was 8 volts on cells all but one at 7.9. We cleaned all of the bus contacts. We went into the maintenance mode on the MFD and found the aux battery to be 12.6 volts and under load it dropped to 11.8 with the lights on.
The aux battery went up to 14.1 volts with the car on. The inverter cooling fluid has movement and there is a slight humming which I believe to be the inverter pump running. The inverter fluid was topped off. The MFD showed the battery bars start at about three fourths full, drop down to one bar. With the engine running the battery bars climbed to the top purple. The engine turned off and the bars continued to climb to all green. All of this occurred in about 3 minutes while the car was parked. There were codes on the MFD while in maintenance mode. I understand that these codes are for the navigation system and the audio system.
I have a 2009 Prius Touring with about 55,000 miles on it. Had it regularly serviced last Thursday at the Toyota dealer/service center, and they said it needed to have the coolant flow control valve replaced due to sticking - so I agreed and they did it under warranty.
On Friday afternoon, I was driving out to the desert and about 50 miles into my trip, the red triangle with exclamation point symbol appeared on my dash, and the word "Problem" beeped on my screen. Then it went off, and then back on a few minutes later. Then it happened again and the high coolant temperature warning light came on the screen...and then went away. I turned off the A/C and opened the hood to check for steam or heat, but there was nothing. Since I was far from my destination, I called the closest Toyota service center and promptly drove there, but the light was off when I arrived. They said they checked everything out and ran the codes, but nothing came up.
When driving home on Sunday, the car did the same thing - Problem Triangle and High Coolant Temperature warning light on and off for varying amounts of time and with no correlation to how fast I was driving or how hard the engine was working. I left the A/C off the entire time.
Today, the car did the same thing after driving for about 10 miles. I brought it back to my regular service center, they ran codes and checked everything out...but they cannot find anything. They said they can't determine anything with the light off, but it doesn't stay on consistently so it's nearly impossible to bring it in with the light on.
A yellow key symbol appeared atop the speedometer. I searched the manual and found no reference to this. I assume this to mean the battery may be low in my key fob. Am I correct or does this mean something else?
View 12 RepliesLast night I made a U-turn (a slightly sharp one) on the road and suddenly I heard a beep and then a symbol of a snowflake appeared in the MFD. I thought maybe it had something to do with the snow tires setting, but according to the MFD that setting is unchecked. This morning the car still has the symbol on. What it means or how to turn it off? I couldn't find it in the owner's manual.
View 7 RepliesI'm parking the car (gen. 2) a long while, so I checked the manual which shows the deactivation button on/off positions. It show the button sticking out more = the off position. However, the car symbol still blinks on the dashboard.
View 2 RepliesI have a 2007 Prius, package 6. It's always worked great, can't complain. I bought it in 2009 with 27,000 miles on it from the original owner.
I have always started the car by pressing the start button with my foot on the gas pedal. My key fob is in my pocket, I don't put it in the ignition key slot. I lock the car by pushing the button in the door handle from the outside. I unlock it by putting my hand on the door handle and pulling on it. My keys are always in my front pocket with nothing else in the pocket.
Yesterday, when I got in the car and pushed the ignition button, I got the symbol of a red key flashing with a line through it, seeming to be telling me I was trying to start the car without the key. I got my key out of my pocket and waved it around, and then the car started in the normal way, by pushing the ignition button, i put my keys back in my pocket. Went out, came back, everything seemed normal.
Today when I got in the car and pushed the ignition button, got the flashing red key symbol (and beeping sound) again. I got my keys out of my pocket and waved them in front of the dashboard but it was no dice. The car would not start. I put the fob in the ignition slot and the car then started. I went to my location, turned the car off, tried to turn it back on without the key in it but it still had the flashing beeping key picture on the otherwise dark dashboard. I tried to lock the car by pushing on the door handle button but there was no response. I opened the door and used the button on the inside of the door to lock the car and closed the door. i used the valet key, taking it out of the fob and using it to reopen the door. Pushing on the lock/unlock buttons on the fob had no effect.
When I got home, the car still would not respond wirelessly to the key fob. I got my spare key fob from the house and tried using it to start the car wirelessly. It had no effect.
I searched this forum and read about the button under the steering wheel. I went back to the car to search for the button. I saw the button, labeled with the word 'Key.' But before touching it, i tried starting the car keyless again, pushing the ignition button. It started normally. Everything worked normally, lock/unlock, ignition. Key fob not inserted into the slot. I decided not to do anything with the under steering wheel button.
I would like to ask whether this sounds like there is nothing wrong with the key fobs but there is some problem with the car internally.
Are there ways I can test that, by trying other things that would be affected by the battery, if the symptom comes back again? If there's an internal defect causing the problem rather than problem with the fob/s, would any of the causes be warranty repairs?
The car currently has about 67,000 miles on it.
After driving for 2 or 3 miles my car turns on this red triangle and says "problem" on the GPS. All the threads i have found this is accompanied by a check engine light but mine does not. On the gps there is also a symbol that i looked up in the manual, it says to take the car to a dealer. is there any way to know exactly what this triangle means? There is not CEL tripped, tried 4 code reader and nothing.
View 5 Replieshow can I unsure someone won't drive off with car when I start up to warm it? I mean I can't lock the door with it running. Not going to install a remote start (if that's even work) Wish it would not drive when put into gear to ward off thief, without key fob. Is there a solution? 2015 regular Prius.
View 19 RepliesI've never had an issue with my 2010 Prius except for an occasional need to jump the battery after leaving a light on. Today after finding I left the interior light on, the car wouldn't start. I assumed the battery had drained, but then something strange happened. The car would not fully shut off. The starter button shows a red light and there is a loud continuous beeping sound even when the door is closed. Additonally, the car will not lock. When I foreceably locked the doors, they unlock right away. The yellow exclamation point warning light on the left side of the dash is on as is the malfunction indicator light that looks like an engine.
I tried to jump the 12volt battery through the charging port under the hood and got absolutely no response at all. And the continuous high pitched beep is still going after an hour.
Sometimes when I startup I get the message "Air Conditioner Off". This has only been happening for the past few weeks and never before. I wonder why now and not before. Have 22,600 miles.

View 19 RepliesI bought a used 2008 prius about a month ago with 44,000 miles. Tonight when I went out to get something out of the car, I noticed a flashing light on the dashboard. It looks like a car but is flashing so quickly I am not certain. I can't find anything about it.

View 9 RepliesI loved my Prius to death on day 1 but now I am having some frustrating problems starting and stopping the car. I drove the car on Sunday for several journies with no problems. I even did a 120 mile round trip in which i cruised at about 65 and 70mph to test the mpg (around 50-55mpg which I was quite happy with)
Anyway.. onto today..
So I tried to start the car at 7:20 for my usual drive to work and tried the usual approach..
1) unlock doors
2) put key fob into slot
3) put foot on brake
4) press the power button
but nothing happened. I cant remember the sequence but various messages popped up. After that I thought i would lock and unlock the car but i wasnt able to, so I stepped out of the car and was still not able to lock the car. All I could do was lock from the inside the 3 other doors and manually lock the driver door. (and call a friend to pick me up!). So this evening I have tried again. still problems..
I have to use the mechanical key on the SKS to open the door, then plug into the slot on dashboard to start the 2004. Replaced battery, nothing changed.
There are two causes I suspect:
1. The CR2023 Battery was bought on Amazon for cheap, about 6 month ago. What's the voltage should be if no load?
2. The plastic cover on the SKS was broken. It could be that rain or not-so-clean-water gets into the electronic part.
Yesterday, my vehicle stability control light came on along with the ABS symbol. I stopped the car and turned it back on and the car would not come out of Park.
I restarted the car and was able to shift into drive but, both symbols remained and the MFD showed no regenerative braking and the brakes were clearly mechanical only by sound and feel.
I think I took a rather short trip with the parking brake partially engaged, I was talking to my son who was home for the weekend.
I set and released it several times with no results. I finally parked the car, set the brake and checked for codes in my Scangauge-none. But, I did a "clear codes" anyhow.
I've only driven home yesterday and this morning to work. So far, nothing unusual, I have my fingers and stubby little toes crossed.
I woke up this morning and started up my 2005 prius to warm up. I live in New England and it freezing out today. About 15 min or so later I go back out to the car that only had the heat on and I find a large red caution symbol on the dash. I check to see if the e brake is on and thats when I look up and see it, the main battery symbol on the gps screen. I looked at my battery and only one small bar was lit up. I then noticed that the engine sounded like it was giving all it had. I turned off the car and went inside to call Toyota. I am waiting to hear back from someone in service to tell me if I can drive it. I have under 90k and it is due for an oil change maybe it's over by 100 miles. I did get the recall for the water pump and was planning to have it done with the oil change.
View 9 RepliesTook the Prius on a little journey the last couple of days. Drove over 700 miles, mostly highway, and the weirdest thing happened to me during that drive.
History: This Prius has a bad HV Battery, in that about 3 modules are weaker than the rest, and the car likes to throw 3006, and corresponding codes for the modules themselves as it sees fit. When this happens, the "BRAKE" indicator along with the "ENGINE SYMBOL" pop up, and the engine revs up above 2000rpm, yet less than 3000rpm, and the drivetrain shuts down output to the wheels. Best I can explain it anyhow.
Other than having to pull over to the side of the roadway, reset the codes and start the car again, all operates fine, until the codes pop up again.
But in this long drive, I was able to repeat 5 times, what has happened once in a great while, but these times, I was able to realize something during the events.
The car, when traveling down an incline, at the very moment the codes were thrown, would start surging in speed, and would not disengage or stop, even if I took my foot off of the accelerator and pressed the brake. I could press the brake long enough that the drivetrain would finally disengage, yet the engine would rev up well over 3000rpm, so much, I felt it best to turn off the keyswitch, and coast to the side of the roadway.
Last month my red triangle would pop up along with the yellow head light symbol. Most times it would be for a few seconds, other times it would stay on for a few minutes. Today I rotated my tires and I thought I would check out leveling sensor while the tires were off.
I took my left rear tire off and this is what I saw when the sensor was removed.
So everything looked normal to me. Looks can be deceiving. I've seen pictures on here of leveling sensors where the guts are completely rotted out. That's what I was thinking I was going to see. Here is a picture of the bolt side of the sensor:
Again, it looked normal to me. If you don't know what you're looking for, especially if parts aren't mangled, it can look normal. So I took the four screws off of the sensor and this is what I saw:
The inside of the sensor was in pristine condition! The springs are shiny gold and there was only a small amount of dust inside the sensor. I started to think about how the sensor works and I figured out that the sensor must move in some way. Hmmm. But there was no bracket on it to turn the sensor.
