Since the weather has dropped a little I was wondering if it's normal that the car sitting on in the drive way, on, would idle up a little just before shut down. I mean shutdown to use the battery not shut down turn the car off. It idles fine for the warm up stage then just before it shuts down to be available for ev mode it spins up a little.

5 hrs after shutdown i head something running under the car,, was louder under the car vs listening thru the inside,,, sounded like a fuel pump or small fan.
I have a 2010 IV and after driving for an extended period and then shutting the car off I get a loud noise about a minute or a little more after shutdown. The best I can describe it is that it sounds like someone is dropping a 3 pound dead chicken from about 10 feet up onto my hood. It is consistent and is not any of the whirring or buzzing noises I normally hear. I also have a 2009 Touring and have never heard anything like this.
View 3 RepliesI have a Gen III Prius 2010 with about 50k on it. I've noticed over the past month that when the ICE shuts down at a stoplight, the car will surge forward a bit. If my foot isn't on the brake really hard, it will translate to the car actually moving forward until the ICE is totally off. If my foot is on the brake hard, you can feel it push against the brakes, and then the car settles back in place. It doesn't happen every time, so it still takes me by surprise.
View 3 RepliesMy Prius is having a problem during cold start. When I bought it, the cold start was very energetic with a high rev tone then gradually regulate to a normal pace and petrol engine shuts down. But about 4 months I noticed the tone of the cold start has changed, it starts with a weak and low engine rev and delays to turn off the engine. Today it took about 10 mins to power off the engine. Got 2 months I changed my 12V battery (Bosch now), thought that these symptoms was to notify that battery is failing. But the problem is persistent despite I put new battery..
View 7 RepliesI hear this loud grunt noise coming from engine area or brake area at random times, not all the time. I can feel the grunt, sounds bad.
1. Coming to a complete stop hard, grunt.
2. After shutting car off, stepping out of the car and 3sec later GRUNT.
3. Idling sometimes it grunts out of no where.
I have a concern about not hearing the whirring sound after shutdown anymore. I know that the sound comes from a small electric-pump that pumps 3 liters of coolant into a thermal container (to keep it hot) everytime I turn the hybrid system power OFF. When the power is turned back ON, the coolant is pumped back into the engine.
I've noticed that after I got an oil change and tire rotation at Pep Boys the sound is no longer there after shutdown or power up. Then after a couple of days I took the car to the dealer to fix the tire rotation (because Pep Boys didn't do a good job at rotating the tires, there was a woo woo woo sound while driving) and the dealer also did a multi-point check, but they didn't say anything was wrong with the car.
Yesterday after a 45 minute drive home (GA and above 90 degree heat), I noticed a moderately high pitched whining noise after shutdown. The noise continued for about 5 minutes. From my understanding, the inverter coolant pump redistributes the coolant after shutdown and I have heard a humming noise previously which I assumed to be this action.
View 10 RepliesYesterday my 2008 Prius with 95,000+ developed a new noise after turning it off and it has me a bit worried. I took an audio sample? Last night it occurred for like 5-10 minutes. Now today I went to turn it on and before I even pressed the power button it made another noise that I've never heard before which I didn't get on audio. It turned on fine, I let it run for a few minutes and then shut it off and the noise I got on audio occurred for several minutes. The noise comes from the driver's side by the electric motor. The clip should play in iTunes or Winamp, took it on my iPhone so its kind of low in volume.
View 19 RepliesI have a 1989 toyota Celica ST with a 2.0 in it.
I have idle problems after the car has ran for about 1.5- 2 hours. It has a new cap and wires and plugs and a new intake on it and it still does it. I have it parked for winter right now because it cant get around in the ND winters so i'm just trying to get some ideas right now.
Also i pulled the cap off and there was oil in it.
2005 Prius, 90k, original battery I think, started beeping on shutdown, then wouldn't start today (cold). Got a new battery, but the back hatch wouldn't open, so I tried to jump it following owner's manual instructions. Headlights came on at first (although stalk switch was off), but doors/car wouldn't respond. Disconnected and reconnected jumpers, lights off this time, still no response when trying doors or starting car.
View 7 RepliesRecently (5-6) months my Gen II has been making some weird sound when I turn it on before the ICE starts. Also when I turn it off after the ICE shuts down. I really don't know how to describe the sound so I took some clips of it. Sort of a high pitched grind maybe? Car has 45xxx, just had the Hybrid water pumped replaced.

(CORRECTION: AM1 fuse blew, not ECU-IG)
(Correction 2: Update 6/3/2014 AM-2 fuse blew, not ECU-IG)
What caused my shutdown and the ECU-IG fuse to blow while driving normally? I want to get educated prior to the dealer's response.
2006 price with going back - rest about 105K miles on it. Recently the dashboard lit up like a Christmas tree with all the warning lights. Battery fan runs non-stop as soon as the car is started and if driven, the gas engine never turns off. When it happened I was circling the neighborhood looking for parking. After about 5 minutes the car dropped out of drive and wouldn't go back in until I shut down and restarted. The battery still charges, and holds a charge when left parked. What is most likely the culprit before I bring it in this afternoon? The dealer is 3.5 miles away (about 15-minute drive in Chicago). Am I risking further damage driving it in? Should I call for a tow?
Update: A check of the inverter coolant reservoir shows that coolant is flowing. Ripples on the surface.
I went to a local oil change place on Tuesday morning for an oil change. Had them change the air filter (engine and cabin) at the same time. The odometer is at about 165k on my 2006 base model Prius. When the job was completed and I pushed the power button, Christmas tree. Giant red triangle of death, check engine, and the display picture with the "!" in the middle. Can't put it into gear. Engine runs briefly and cuts out. Maybe they tripped a wire when they changed the filter? Nope, all was good there. Silly little tech put it on his code reading machine to no avail.
I called the local Toyota dealership that I hate and don't use and they gave the oil change guy instructions to jump it. No dice. So I leave it in the bay and call a tow truck. Towing guy figures out how to get it into neutral and puts it on his truck to take to local hated dealership (mistake). Long day of fighting with oil change place, followed by super star service from larger dealership in Austin (60 miles away) with the service rep I always use. He diagnosed the likely problem over the phone. I didn't even let local hated dealership do the diagnostics. I put that little Prius baby on a flatbed and took her to Austin.
Well, the codes pulled were P0A0F (engine failed to start) and P3190 (poor engine power). Well, that is the magic combination along with the experience of my service rep and tech to confirm that too much oil was added. It's was about a half of a quart. Crazy, right? Well, they cleaned the throttle body, interior of intake manifold of oil residue and all is well again. The big battery was completely dead so the dealership charged it up for me.
Next morning I pick it up and big battery is charged about halfway. Not sure if they completely charged it the night before. However, by the time I got to work (maybe 5 miles), battery indicator was full (green). I had an oddity when I had a longer stop light idle later that afternoon where the battery went from 4 blue bars down to purple, but drove the 60 miles back home and today the charge seems to be fine (4-5 blue bars). I have a sneaking suspicion that there may be more issues, but for now all is well. I'm going to get the 12V battery changed soon because we're still riding on the original.
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.

I have a 2011 prius. Lately after work when i get back in the prius the battery will be half what it was when i parked it in the morning. Is my battery dying already. im at 36,000 miles
View 6 RepliesI believe I have a pretty good understanding of how the HSI works, but for some reason I feel like my car has been reacting differently.
As I understand it, the left half of the HSI will cause the electric motor to operate without the ICE (assuming there is enough charge in your battery and you aren't running A/C etc).
My girlfriend has a 2010 prius with the navigation package. We go to the drive in movies quite frequently because it's cheaper and close to us. Every 30-45 minutes the prius will automatically shut off the battery. The interior lights turn on and the sound goes off.
We are kind of getting tired of getting dirty looks when this happens. So we're wondering if there is a way to take this setting off.
If I put the Prius in park while I get out and mail a letter, engine temp is 190, I can get back in and drive off on electric, zero rpm's. However, if I push the start/stop button, mail the letter, and restart the engine (temp is still 190), I cannot get the engine to spool down. It keeps running for a few minutes.
View 4 RepliesIt seems like you can't... It can't be unlocked if you have keyless entry so long as the car is running... Why? Any way around this?
