Prius (Gen 1) :: Red Triangle After Having Car Parked In Extreme Rain / Heat Pop Up
Aug 25, 2014
I have had the red triangle after having the car parked in extreme rain/heat pop up when I start the vehicle 3 times in about 6 months. The first 3 times I did not have Techstream so I just cleared the codes, but the third time I finally read it and had those 3 codes, the first two I assume being most important. I clear the codes each time I see them and they stay off 1-2 months. About 140k miles on car. New 12V battery. No driveability issues. Car still gets decent 60 mpg in summer, 50 in winter.

I was driving the car and triangle popped up and engine would not shut off while parked (key on) I hooked up the non prius aware scanner (carry one with me at all times) and don't remember the code, but it was a "HV malfunction".
I didn't shut the car off to clear the code as I was not home and attempted to drive it home, meanwhile engine never shut off. I had to come to a complete stop at a red light and the car died. tried restarting it but nothing. so I pushed it off to the side of the road and cleared the code. Tried again and nothing. didn't start, nothing. it beeped and error code popped up. Checked the code and it was p3125.
I know there are subcodes but online it was leading to inverter. but I replaced the inverter last year with a re involt. I had the car towed to my job for $50, to have it towed home, would cost roughly $168. When I got it to work, I did the screen thing and checked the 12v battery and it was reading 10.9 I have been meaning to get a new one for about a year now so I did.
I purchased a new optima battery and installed it yesterday, cleared the codes, tried to start it and nothing. error code p3125. What leads me to believe that it may be a transaxle, well actually a Mg2 is when my inverter went bad, it would start then shudder and die then the triangle would pop up. this time around, it doesn't even start. I have an appointment with the dealership to get the code with subcode read on Tuesday 10/15 for $98.7.

Yesterday I parked on a very slight slope (the front sat maybe 1 half to 1 foot higher than the rear) for a few hours. It was the end of my carport. When returned to move it forward and park, it was dead. So I put a charger on it and got it started but then the red triangle warning light was on saying that there was a problem with the parking system.

I've read other posts where owners report using previous gen for camping trips and leave the car on all night for AC/Heat. I have a similar but much shorter timed use case. When my wife is in shopping, I use my car as an office with laptop and phone going, and usually just bear the very hot days while parked for an hour, sometimes two. Would the 2016 Prius provide the opportunity to keep the car on in this way, and is there any detriment to its motors or electronics when keeping it on like this for extended periods of time.

Extreme tempertaures in NJ this week.Can this car handle this extreme heat without stripping the head bolt threads? Less than a minute after I start my car in this heat my fan turns on, yet the temp gauge is still below the middle mark..Can this car handle 90 degree + temps (also have A/C) on?2006 Camry Le 60K Miles--replaced coolant around a year ago.

I have several problems with my 2008 Prius that I will try to list below and I have done much of mechanic work myself but now I am a little stuck with some of the codes that are coming up and with some of the problems my Prius is experiencing:
Here are the codes that were scanned when I took car to a local parts store:
Coolant Temperature Sensor Evaporated Emission System (Vacuum Leak)
p3193
Accelerator Pedal Position Sensor
Pump Control Circuit Low
" High
I replaced the thermostat and now I get the red light displays on the dash anytime I go over 45 and the thermostat light on the panel displays there is a problem. I think there might be air in the system. Should I have a mechanic bleed air out or is there an easy procedure that I can do on my own to fix this problem?
I have also purchased a water coolant valve and this will be my next part to replace at 106.00 dollars. I am not sure this will fix my problem with my heat but I do not want to replace the heater motor because those run 630 dollars each.
Being that it is winter I want to fix the problem so that we can drive the car with some heat and not get the red light to come on intermittently. How to get to the root of these problems listed above?

My 06 prius takes a very long time to provide heat to the cabin. In temps below 20 F it can take 20 minutes. Today in 16 F weather the red triangle came on, followed by a problem banner, followed by a thermostat symbol. The triangle and symbol turned on a off a couple of times over a 5 minute span. I had been driving the car from a cold start for about 15 minutes when this happened. The car did start to produce some, but not a lot, of heat at about 20 minutes into the drive. I was also forced to use the defroster intermittently for the first 15 minutes (blew only cold air). After parking the car for 20 minutes I drove 20 minutes home with no triangle or thermostat symbol. Most of the way home I had sufficient heat.
I do have the front blocked with pipe insulation. I have owned my 06 prius for over a year and it has 257,000 on it.
Could the thermostat and triangle be caused by a low engine temp? If so would a stuck thermostat be a potential culprit?
Can I assume that if my car is blowing cold air when I am asking for heat that the engine is not over heating?

Last night and this morning we had flooding rains here and the excursion was sitting outside in it.
Later this afternoon, I went to pull it up a little to get a motorcycle ouut of the garage, and it started, but very roughly. Check engine light on, would idle at times, and sometimes would die on its own or when I put it in drive. The OD light on the gear shift was also flashing.
Didn't see any pools of water in the engine compartment, around the firewall or anything that would show water had gotten into some electrical areas of the truck.
My OBD reader isn't reading the diagnostics plug for some reason, im gonna go buy one here in a minute.
Plugs, boots, COPS?....why the hell the OD light flashing when in park? Start removing, inspecting, replacing or tow it to the dealer?

Truck (04 excursion, 2WD, early build 6.0, 160k) started missing and rough idle on way home from work after sitting all day in rain - parked. started fine in morning and drove to work with no trouble - it was raining over night too.
To get you up to speed. for a few weeks before had intermittent trouble starting. would fire up as normal, fast and loud, but then stall immediately (usually after sitting overnight). would start back up but with a little long on the key and some gas pedal action. only happen one out of ten or twenty starts and seemed to follow getting fuel in unknown locations while on a trip out of town. decided to change out fuel filters and drain separator. seemed to fix it for a week or so then it happened again two days before above event, while weather was dry. Not sure if related but only recent problem to speak of.
Back to current:
- no check engine light or codes (I have a scanner)
- stalled out close enough to home the night in question I rolled it into driveway and tried to start it while rolling in neutral - no start
- once parked in driveway also no start
- next evening wanted to get it into garage (to dry off) and it started but rough idle and missing. this was after 24 more hours sitting in rain.
- been in garage 24 more hours and this evening got it to run but same result (rough idle and hard start). tried to check connections (mainly FICM) and move wire loom around - still same.......
Where to check next, need some diagnostic...

Don't get much rain here in SoCal except during the winter. After the last rain I noticed that there was water in the heating/ac vent system - or at least that's where I think it was.
When I made a right hand turn some water slopped out onto my foot and gave me quite a shock for a second till I figured out what had happened.
I suspect that there must be some kind of drain tube for the vent system that's become clogged, but before I start crawling around under the truck and dash I figured I would ask here first. Any useful tip on clearing the clog?

If the hydraulic brakes go out what is the best procedure to brake in a Prius? No, I don't envision this happening just a "what if"?

2005 Prius w/90,000 miles.
This morning I got in my Prius and started the car. I was waiting for my son and almost absentmindedly I put my foot on the gas enough to get the ICE revving up. The car was parked with a very slight incline forward (a few degrees at most). After a few seconds the car thumped backwards. It then continued to do that continuously with a thump about once a second. It's not a hard thump, but it's very noticeable.
It is almost as if a very small amount of power is being applied in reverse and then released quickly. I shut the car down and was able to replicate the issue. There are no error codes on my OBD2 and no unusual engine lights. Is it normal?

Normal to have a buzzing sound from the car while parked with the ac on? Its not terribly loud but can be heard inside the car with windows up.

So, I went to a hotel tonight and gave my car (2010 Prius II) to the valet. When I came out about 4 hours later, a different valet guy said they had a problem with my car and that it had no power. But, somehow, they were able to drive in reverse and park it near the entrance. This must have happened shortly after I left the car with them.
The car would not start, but a dash light was blinking that looked like an outline of a padlock (it was blinking too quickly for me to tell). Also, strangely, the vents were blowing air (albeit, at a very low setting).
Someone with the hotel came out with a battery charger and we hooked it up to the terminal in the front engine. As soon as the battery was attached, everything in my car lit up and I was able to start it up.

I recently discovered a squeak when the car is parked and I move the car forward and backwards. The harder I push, the more it squeaks. I went to a mechanic who told me the struts were "bad" and needed replacement.

So my window was left partially down today and it poured down rain! The window that was down was the passenger side rear window. The handle on the door was full of standing water and my seats and floor mat were pretty soaked.
The speaker at the top of the door had water in it and I can't get it out by just wiping the cover. Is there an easy way to take this off and try to make sure everything is OK?
The vent for the batteries got lots of water in it too, this is dangerous?
Also, it's my first time with leather seats and I don't know how the water will affect them. Anything special I need to do?
I wiped up and soaked up everything I could with towels but still worry about the lasting damage it could have.

Experienced the cargo door got stuck after rain? I have started to notice it and realized that it was after it got wet in the rain. It makes the electronic noise trying to open, but takes about 5-10 tries to get it open.
Also, is it impossible to make the cargo door electronically open/close like many other car models? I hurt my shoulder, and it is very hard sometimes to reach up and close it.

I parked the little dear in the garage about 9:30 last night. I went into the garage this morning around 6:30 and I noticed how still and quiet it seemed. I then opened the garage door and went outside for a few minutes. When I came back in, I hear a low whirring sound. I went back outside to listen, but it was definitely coming from the Prius, perhaps near the back, underneath.
The hatch was open; I closed it, but the sound didn't change. The fob was in the house, and I didn't open the driver door, so it wasn't the brake pump. It lasted at least 2-3 minutes, at which time I was too bored to continue listening, and I went back to weeding and watering.

I've had my 2015 Prius Two for almost 6 weeks now, and so far am loving it. However, I noticed something strange today. I'm pretty sure that when I parked at work this morning, the hybrid battery was nearly full (two bars shy of full, I think). When I came back to leave work (~6 hours later) and started the car, the hybrid battery was down to only two bars (as in two bars above empty mark).
