Prius (2004-09) :: Came To Stop Suddenly On The Driveway - CEL Along With Other Warning Lights Came On
I own a 2004 Prius with about 122000 miles. Today I was driving up a steep gravel driveway, going very slowly and slipping a little. The VSC light was blinking and then the car came to a stop. At that time, the big red warning light came and check engine light came on along with a message on the info screen reading "Problem". AND most distrurbing of all, a pinkish car symbol warning with an exclamation mark through it that the manual tells me to take it to the dealer immediately.

As far as the owner can tell, the car is running fine. He hasn't driven it aside from getting home after the light came on. It seems to give a very informative error message. What it's saying?

Bunch of warning lights appeared and the dealer said it's code P0a80 and they recommend replacing the battery. I'd like to try to fix this myself and would like to hear your thoughts...
Plan is to check the traction battery for corrosion and use a voltmeter to test the cells and replace if needed. Prius 2004, 158,000.
Prius (2010-12) :: Car Beeped And Suddenly Hit With Multiple Warning Lights
I drive my 2005 Prius 40+ miles each way for my commute. I bought it in the fall of 2007 with 56k miles already on it, and with my commute I'm up to 140,000 miles already.
This morning I was about 5 minutes from work, cruise control on, and deeply absorbed in listening to a podcast. I was startled out of my reverie by several things happening simultaneously. The car beeped, the cruise control kicked off, and multiple warning lights lit up on the dash, with a warning icon of some kind also on my MFD.
(Once stopped, I looked up the warning lights. They were: Master warning light; Check engine light, or "malfunction indicator lamp", according to the manual; YELLOW Brake system warning; VSC warning light. On the MFD, the Hybrid System Warning Light was on.)
I was on the highway doing about 70 and I had just crested a hill, so I allowed the car to coast on the downside while trying to access the situation. I cautiously pressed the accelerator, and though the road noise made it impossible to hear the engine, the car seemed to still be driving normally. The Energy Monitor still showed normal flows between battery, engine, and wheels. I had one final, short uphill climb before my freeway exit, so I chanced it. I took it easy and allowed my speed to decrease on the uphill so as not to push too hard, just in case. Once off the freeway, most of the remaining mile is downhill or flat - I can often make it to the office without the engine, and in fact I did so this morning.
Once at the office, I put the car into Park and grabbed the manual so I could identify all the warning lights before powering off the car. I turned off the Prius, let it sit for 5-10 seconds, and powered it back on. The brake system warning and VSC lights did not come back on - only the master warning light, and "check engine" lights reappeared, and "Problem" on the MFD was again replaced by the Hybrid System Warning icon. After the usual 10 seconds, the engine started normally and responded to the accelerator.
One additional note: After the freeway exit, my car is usually at 1 green bar or just below on the hybrid battery. Immediately following the freeway exit is a steep downhill that usually puts the SOC to completely full. That was the case again today, and as often happens, that full charge was able to take me the rest of the relatively flat, distance to the office at my usual 25-35 mph. I mention this because whatever might be setting off the warnings, the Prius still seems to be managing the charge level normally; at least in the admittedly short period I was able to observe it after this occurred.
Prius (2001-03) :: Suddenly Car Started Stutter And Warning Lights Came On
I have a 2003 Toyota Prius with ~250,000 miles. Yesterday I was driving and the vehicle started to "stutter" and the warning lights came on. My ScanGauge indicated code P3125. I drove normally for 2-3 miles and parked for a bit. When I returned, I was able to start up and drive home with no problems (about 20 miles of highway and stop & go traffic), and drove most of this morning, but around noon it happened again and this time the vehicle would hardly move at all. It had no reverse and I had to push it out of the parking spot. I managed to limp home and park it.
View 11 RepliesPrius (Gen 2) :: Error Code C2310, C2318 With Warning Lights Appeared
I actually just bought a used 2004 Prius with 207,011 miles on it from out of state. I had a car shipped to me by a flatbed trailer. I just got the car the last weekend. However, It has a yellow engine light and a big red triangle with an exclamation mark (!) on a dashboard, and a red car with ! on top left of a display screen.
I drove it to a DMV to get it registered and took it to Pep Boys near my place since I have to get it an emission inspection within 10 days of registration anyways.
They ran a diagnostic test and found 2 current error codes (C2310-open/short in battery circuit & C2318-low voltage error) and 1 history code (P0A80-hybrid battery pack needs replaced), so they didn’t perform the inspection; otherwise, it would have a failed record). They told me that the car has had problems before and the problems are about a hybrid transaxle and a hybrid battery pack. They also told me that I need to visit a Toyota dealer to get them fixed in order to pass the inspection, and they warned me that is going to cost me a large four digit probably . So, they suggested me to just trade it in because it is not worth repairing. They also told me that a dealer who sold me the car probably would have done something to the car, that’s why it didn’t illuminate any warning lights before.
I tried to gather as much information as I could, so I asked the shipper if he noticed any warning lights but he didn’t think so; one thing he noticed was the hybrid battery isn’t charged because the engine started every time he moved the car.
I plan to take a car to another auto shop near my place as well in order to have them double check the issues and give me a repair estimate before taking a long trip to Toyota dealer.
Prius (2004-09) :: Transmission Lock Error Message Only Reappears When Slow Down To 3 Mph
I've read around the forums stating the P Lock error is common from a low battery causing the vehicle not to start.
The strange thing is that my vehicle DOES start and the message appears and the dash shows READY and I am able to enter gear and drive. If I hit a button on the console the message goes away and if I'm driving at higher speeds the message does not return but the large triangle stays. The error message only reappears when I slow down to 3 mph.
The error does flash back on the screen when I slow down to stop or sit at a light. The car does not shut off during this it just flashes the message and shows the large triangle.
My battery test shows 12.3v on no load and 11.6 on a load. I would hate to replace my battery and have the issue not be resolved.
Prius PHEV Plug-In :: Early System Shutdown - Warning Lights / Error Codes
Have been having cascading problems since installing PIS 10kWh system in April. Early system shutdown, failed BMS boards, then triggering of Prius warning lights. The latter required disconnecting the 12v battery to 'reboot' and cancel them per Robb of PIS. But then, when attempting to do an electrical load test using air con & other accessories, we triggered several yellow warning lights that do no go away with a reboot. Have been told that we need to have a dealer read the codes to troubleshoot.

Prius (2004-09) :: Slow Then Fast Paced Beeps While Driving Without Any Visual Warning
My 2nd gen 2007 Prius started to show a strange behavior today and I don't find any answer to it. While driving without any cars close, with all seat belts closed and nothing on the passenger seat I started to hear slow paced beeps (approx. 20) then fast paced beeps. When I switch off the car and started it again I got the same beeps after approx. 30 seconds. I never got any visual warning and the OBD reader doesn't show any error code.

I had just picked my kid up from school, as I turn out of the parking lot my A/C stops blowing cool air, I check the A/C screen and it still says it's set on High with temp at 68. However, it is blowing very low with warm air. Seconds later the dash lights up with numerous warning lights. I'm on the highway and I'm able to gather speed, but each time I do I hear the engine revving like crazy. We only live a few miles from the school so I am able to make it home. Once home, I turn off the car and turn it back on. The only warning lights displayed now are the red triangle and the yellow check engine light. I turn the car off, pop the hood, I check the belt and it was fine. I checked the oil and it seemed fine. I check the coolant overflow and it was empty.

Prius (2004-09) :: No Dash Lights Occasionally - Gas Error Code
My car was working fine except for occasional no dash lights. Unfortunately where my dash lights don't work sometimes I can't see my gas gauge and I ran out of gas today. I manage to make it to the gas station on battery power I presume. Filled the tank up with 11 gallons and the car seemed to work fine for the remainder of my trip(about 5 miles). So I parked at my destination and went inside for 30 minutes and then I went back out and started the car. I attempted to clear the out of gas error code and all of a sudden a whole Christmas trees of lights popped on my dash. I rescanned and these codes were read out

Prius (2004-09) :: VCS - Red / Yellow Exclamation And Check Engine Lights All Suddenly Turned On
While my car was idling in a CVS parking lot, the VCS, Red Exclamation in a triangle, Yellow Exclamation in a circle and the check engine lights all suddenly turned on.
In reading the forums, it seems the two most likely issues would either be the inverter pump (which I had replaced as part of the recall, and I see the fluid moving in the reservoir), or possibly a bad 12v battery (which I had replaced last year with the forum recommended Optima Yellow Top).
I checked for error codes, and there were numerous ones there at first, but I think that might have been related to the old 12v battery dying (I never reset after that). I cleared the codes, and no new codes are generating.
Lexus RX 2010-15 :: ABS / Master Lights And Audible Warning Activated Suddenly
We were driving 2015 450h with 2200 miles on a slight downhill grade about 50 mph. Suddenly ABS warning light, master warning light, and audible warning activated. The center console "Brake" illuminated and the information center displayed "check hybrid system".
My wife attempted to pull the car off the road in a controlled manner but even slightly touching the brakes caused them to pulse, braking hard and then releasing. She finally got the car to the side of the road and shut the engine off. I then got into the drivers seat and turned the car on. The messages remained. Tried on an off, still the same. Tried brakes, the seemed functional. Since we were in a location that did not have cell service and it was an unsafe location to leave the car managed to drive it into nearest town.
Turned the car on and off about 10 times over the period of an hour. Without explanation, the car started with no warning messages. Dove the car another 200 miles since and it has now been at he dealer for over a day with no word.
I did see where a few RX350 models had reported a similar problem, but no 450h's. At the time of the incident we were not using the PCS system (off) . I am wondering about that as well since the ABS might be tied into the PCS?
Prius (2004-09) :: All Warning Lights Came On
When I turned my Prius on today, the following warning lights remained on:
red "BRAKE"
yellow "ABS"
yellow "VSC"
yellow exclamation mark inside a circle inside parentheses.
It drives fine. After driving it a bit I tried turning the car off and back on a few times. The lights still remain on.
Prius (2004-09) :: All Warning Lights Go Off
Mine did. I was driving on the highway and pretty much every warning light went off. It was like the space shuttle crashing back to Earth. Freaked me out. Cruise control stopped working also. But I was able to get home safely.
So first, I tried AAA just to see if the guy would know something, but it was way over his head. He did notice my aux battery was failing, but not much else. Then I found a service online that comes to your place to do the work, and they sent a guy out on a Saturday and he read the codes, and did a full visual inspection, and yes, something was up with the cooling system. He suggested I have the dealer look at it because flushing the system is VERY important apparently. Should be done every 50,000 miles.
I was so worried it was the hybrid battery; we all know what that means! So I had the car towed to the dealer (don't drive if your Master/Hybrid light comes on!) and they said, indeed, the pump was gone. And, of course, they found a number of other things included the dying aux battery. It took them 4 days to get the damn part in stock. At least they covered the car rental for me.
Prius (2004-09) :: All Warning Lights Came On
The other night, went to start the prius and nothing happened except all the warning lights came on! So took the foot off the brake pedal and sat there for a minute trying to figure out. What the heck happened?? Tried a couple more times and then suddenly it was fine and it started! Now I have to mention that the outside temp was around 16*,,, not sure if that could have caused this strange reaction?
View 9 RepliesPrius (Gen 2) :: Car Slow Down And Suddenly Lock Up When Brake Applied
I have a 2005 Prius that worked fine until I was told last year (March 2012) my brake pads needed to be replaced and the rotors were warped and needed to be trued. Since that work was completed, when I apply the brakes the first thing in the morning or when it is wet, the car will slow down and then suddenly lock up. This throws me forward and I get a jolt from the seat belt. The dealer has been unable to duplicate it and tells me the brakes are mechanically fine. Sometimes when this occurs I hear a loud clunking sound from the rear of the car. The last time I took it to the dealership they told me the Prius has an issue with the brakes rusting, but they are mechanically fine. I still have my doubts.
