My gen I Prius started having issues. Every time I drive about 30 miles the triangle and check engine light come on with a ding and also my dash lights immediately dim. I just replaced the 12 v battery. Still no fix.
I also switched the fuel pump relay with the horn relay which seemed to work the dash light dimming problem (oddly enough). So I'm not sure what it could be.
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.
View 4 RepliesI have been having some hybrid battery issues. My prius is a 2006 with 198,000 miles. The original battery was replaced at around 120,000 with a junkyard battery. About a year later that battery gave up the ghost and I decided to rebuild that battery. So far that has worked quite well until recently.
My troubles started a couple weeks ago when I got the Red triangle and all the dash lights and the hybrid system icon on the MFD. Naturally I thought it was the battery again. Took it out and checked the voltages of the modules. All the modules where within tolerances. I grabbed a OBDII scanner and checked the code. It was telling me that the Hybrid current sensor was bad. I changed that out with the wiring harness from the old battery.
That lasted for a few days before the red triangle came back. I checked the code and it was indicating one of the blocks was bad. I think P3019. So I took the battery back out and replaced that block with other modules. Almost instantaneously the red triangle came back with two more bad blocks. I think it was P3012 and P3022. So I took the battery out once more and tested all the voltages of all the modules. Everything was 7.86-7.9v. So I decided to start the rebalance of the existing modules in hopes to find some bad modules.
I also bought a new 12v battery and installed that. I got everything back together and took it for a road test. It took about 30 mins before the triangle came back. I grabbed the codes and it was still indicating bad blocks. P3011 and P3018. I am a little at a loss.
There's an ad for a car quite far away from me and one of the photos shows the dash lit up like a Christmas tree. Is this normal during power-up or is it normal when there's something quite wrong?! There is no red triangle of doom shown; I'm unsure if that might be out of shot though. Car is quite high mileage with just over 270,000 km on the clock and is from 2006.
View 2 RepliesI have a 2001 Prius with 150k on it. It has been giving me the triangle warning light and the car ! warning light. I can start the car and drive it, but sometimes when I press the accelerator the gas engine just dies and will not kick back in, unless I stop, turn off the car and restart it. (Issue seems to occur more in hot weather, could be a coincidence) When I start it the engine will run rough and shutter for less than a min, and then run normally.
View 17 RepliesSo I was driving for a couple of hours today in my recently acquired 2001 Prius, when the red warning triangle and the check engine lights came on. The car seemed to still drive fine (70 ish mph cruising). HV Battery? P3000 P3020 Error codes.....
View 17 RepliesWe are having an intermittent issue with car starting up and immediately throwing a CEL, red triangle and going into limp mode. Shutting off the car and restarting it sometimes resolves the issue. I'd love to be able to pull the logs from the car to see what is causing this issue.
View 11 RepliesThis afternoon, after driving about 150 miles, I came home and shut off my 2001 Prius. It was sitting for about 20 minutes before I turned it back on to drive off. Almost immediately, the hybrid warning light came on on the MFD, the red exclamation mark light illuminated, as well as the check engine light, and the motor shut off. I popped the hood, and could hear a high pitched squeal coming from near the inverter. I called my dealer to ask the service department what I should do, and they just told me to bring it in and they will take a look at it. I live over an hour away, so I don't want to bring it there if I can avoid it. I then shut it off and let it sit for a few hours.
After reading about the possibility of the auxiliary battery being bad, I went and turned the Prius on, and then shut it off several times to reset the hybrid warning light (I had to do so in order to access the aux battery information through the MFD). It turned on without incident, and shut off fine, and after being reset the hybrid warning light shut off, as well as the red triangle light. Then, I went through the process of pulling up the battery voltage information through the MFD.
With the car off, and the lights and fans off, the battery voltage read about 10.0-10.5 V. With the lights and fan on, the voltage dropped to about 9.5 V. After getting those readings, I drove it down the road a little ways, just going about 20 mph. It seemed to work fine. The check engine light is still illuminated. With the motor running, the voltage reading was 13.2 V, and then when I got back from my test drive and shut it off, the voltage hovered at 10.6 V with the lights and fan on.
I am having a problem that has been cropping up the last two weeks or so. Steadily, several bulbs on my dash have been popping, but it is very strange as the pictures will attest. Does these are hard wired bulbs or can they be replaced? Right now, I don't want to pull apart the dash unless I know for sure they are replaceable. You would figure the number of times I have taken it apart I would have noticed.
View 18 RepliesI just put in a new starting battery, and it still won't start. When I turn the key to start, the dash just goes dark. It had been sitting for about three months.
2001 Prius
The Problem : The short version of the problem is that, as the description says, the ABS and Brake dash lights will come on for awhile, but then shut off, either why driving or the next time I start my car. The brake fluid level and color seems fine, and I checked the hidden service menu from the control screen, and the computer is not reporting any error codes (though I have not hooked it up to any formal error code reading device).
Problem History : The first I saw this problem was about 4 weeks ago just after I got an oil change at a local Toyota Service Center. They warned me that the lights were on and I should get them looked at (though I had never had an issue with them before). when I started my car after, they were on, but then shut off after about 30 seconds. I did not see them again for a few days, so I assumed it was just something got bumped or whatnot, and was not worried. Later I randomly started my car one morning and they were back on, this time they stayed on for a few minutes before shutting off. It continued to do this randomly, but I never felt any issue with brakes, nor noticed any other problems with the operation.
The first time I saw it come on why driving, was when I was pulling over to the side of the road, and hit a puddle that was deeper than I thought and jerked the shocks a lot. After this the problem started to be more frequent, most noticeably if I park on a hill with the e-brake on.
My Thoughts : I called my Service center, and they wanted 100 bucks for the inspection, and then most likely another couple hundred for the repair. I am not inclined to just dump my money into this without looking it up first, and what I have seen online is that similar cases on other cars have been a faulty abs sensor or some kind of particle in the fluid line. Since I am not seeing any error messages from the computer, nor are the lights consistently on, I am thinking of getting my brakes flushed.
Is there anything I should know about flushing the brake fluid, or should I really take it to a service center. They are asking 130 (plus mostly likely an extra 20 bucks b/c this place always finds little things to tack on) to change the fluid.
My sister was driving her 01 Prius and the engine shut off and all the dash lights came on. I was worried it was the hybrid battery since it is still original. I started the car and it started fine, drove home without any issues. Went to the store, everything seems normal. Read the codes and found P0121 and P3190, I just have a basic reader so I don't have any sub-codes or anything like that.
View 8 RepliesGot a red triangle on dash. 12 volt was dead. AAA recharged it red triangle still on. Why?
So what does a red triangle with exclamation mean? Is it a fatal problem?
Is it safe to drive my '02 with the triangle on the dash? I've tried to get rid of it, throttle body cleaned, MAF cleaned, battery seems good (13v, no load). What else can I do to try and get rid of it? BTW, '02 Prius, 183K mi. It runs good, cycles on and off normally (motor to battery, etc.). The code clears it self after sitting about a week w/ occasional starts, then I drive it for about 50-70 miles and the light comes back on...
View 7 RepliesI took my car to the dealership because it had the red Triangle ! wanrnning on the dash and the red car ! warning on the display panel. They told me the code was P0A82 "hybrid battery pack cooling fan 1 performance / Stuck off" but it was actually working at the time the mechanic looked at it.
He said it would probably need to be replaced anyways so they wanted to replace it. I told them I would wait, so they cleared the code for me. I read a lot of posts of people having the same problem and they fixed it by cleaning the fan. My fan was a little dirty, but not bad at all. Is there a quick way to see if the cleaning fixed the problem?
Ok wife's car '07, complained her dash indicator lamps were flashing on then off for a second a once or twice in a few days, then triangle of death for a second, then all goes away. Her ABS light came on. This last time it did its flashing thing then the SRS light came on. First thing that came to mind was 12v battery. I threw the TechStream on and ran some tests. Saw 4 codes, B1801, B1811, B1421 C1241. Checked voltage at the battery, it was 12.41v with car off. Negative terminal was very loose and had a little corrosion. Cleaned it, tightened it and ran tests again. No tests came up for the SRS as it said "no response", so I am not sure how to test the system.
My concern is this is the second time the SRS B1801 and B1811 codes have come up (Open connection in D squib 2nd step). The first time I went through, replaced the steering wheel clock spring and checked connector wiring, checked the driver's side seatbelt wiring and replaced the side airbag/seatbelt ass'y. Then I sent in the SRS module to be cleared/reset. I wasn't about to mess with the Steering bag, so I didn't test it. Car was fine for 2 months, then it has reappeared. Did this bad battery connection cause this? What am I missing?? What is next?
I have just recently bought a 2006 prius (T Spirit model in the UK) with 46k miles on the clock.
Anyway i took it into a local garage today for its full service, as part of the process they disassembled the brakes to inspect them. unfortunately when they put it all back together, all the brake related lights have come on (VSC, ABS, anti skid, handbrake) and despite the mechanics efforts to reset them, could not turn them off. When the car is turned off the brake pedal now feels loose and makes a funny twang noise as if it has come off its spring. there are also dull noises coming from the brakes when i am driving the car and turn the steering wheel full lock to the right or left.
What has really annoyed and scared me is that when i now drive the car and brake, on releasing the brake pedal i get the feeling the brakes do not disengage immediately, instead there is some lag with the brakes disengaging a second after i have removed my foot from the brake pedal and makes the car jerk a little before coming to a stop. the car also feels sluggish to drive and on the drive back home only managed to achieve 45 mpg (heart breaking!). the mechanic has promised to take a look at the car next tuesday (we have a long public holiday this weekend so most stores will be closed) leaving me to suffer 4 days of anxiety and non use of my car.
My car has 80,000 miles on it and i just recently purchased it from a dealer with no warranty. I bought it at 65,000 miles and everything seemed to be just fine up until last night. the emergency triangle popped up on my dash along with my check engine light, ((!)) and VSC. I have since then taken it to midas to get an oil change and get the codes read.
View 4 RepliesI 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 RepliesRecently, 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?
We're on a road trip and the alarm tone goes off. The dash displays the brake warning and the red triangle (and the touchscreen has a car outline with an ! in the upper left). Also, the cruise control no longer operates. We return to El Paso and the dealer utilizes several hours and two diagnostics to tell us the Hybrid ECU needs to be replaced. Unfortunately, they can't get our Prius back to us until Monday, the day we are supposed to be back home starting work the next day.
We plan to call the other dealership in town in the morning. But is it safe to drive our Prius in this state? Can a regular garage make the repair? My father-in-law, an automotive repair professional back in Missouri, says that he isn't surprised if an ECU needs to be shipped from a Toyota distribution center since the part isn't regularly kept in stock by an auto repair shop.
