Prius (2004-09) :: Noise After Shutdown Occurred For Like 5 - 10 Minutes?
Mar 15, 2011
Yesterday 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.

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.

Twice during the 6 months that we have owned our 2010 Prius, a loud clattering noise from under the hood occurred upon startup. After shutting it down and restarting, all was normal. It sounded like an engine that was getting ready to throw a connecting rod. The dealer could find nothing wrong and when I contacted Toyota's hot line, they were clueless as well. One service writer suggested the ABS as the source, but I've owned 5 other cars with ABS and never heard anything like it.

92 Dakota 3.9L ... Starts and runs great. Engine shuts down, usually within first 30 minutes after starting. No shutter, just as if you turned off the key. It has not been an everyday occurrence.
I can wait 2 minutes or spray brake cleaner in the intake and it will restart. It will run the rest of the day and never happens again on the same day, even with multiple restarts and driving 100 miles.
I have installed a new ASD relay, new fuel pump relay, new fuel pump, new crank sensor and new air valve controller on the intake. They can't seem to catch it when it happens.

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.

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.

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.

Recently (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.

I just bought a tranny (02J) and I'm about to pull mine out but I'm scared to pull it off just to find out that my clutch is fried. I was at a light, stepped on the clutch, put it in first release the clutch and gave it gas like a normal person would and a bang and clatter noise occurred, I pulled over and when I stepped back on the clutch, the noise went away, released it and the noise came right back. its like clattering metal keys every time that I release the clutch, even in neutral. So eventually I put it in second and it drove normally and then got it to my friends house down the block and now its sitting there.
1.8t 2002 golf 5 speed btw.

Drove the vehicle today (current at 156k miles) about 40 miles then came back home. Left again to run an errand. After coming out of the store and starting the car, a very pronounced 'whine' occurred. It kept whining for about 2 miles and with 3 blocks left to go, the whine suddenly stopped. No CEL appeared and the radiator temp was normal, oil level was fine and the pwr steering fluid in the reservoir was at the max level. I suspected it might be the p/s pump but, if so, why did the noise cease?

Twice this happened today. When I inserted the ignition key, strange noise occurred under the dash. It sounds like some actuators or motors are being activated. When I turned on ignition, there was nothing, like the battery was dead. I had to wait until all these noises stopped, about 1 minutes, before I could start the car. After the car is started, I noticed that the avg mpg and the time on the trip computer had been reset. This almost sounds like the onboard computer was being rebooted. The terminals on the battery were checked to be very tight.

I have a '97 Ford Escort. I drive over an enormous pothole. Immediately, I heard a dragging noise on the left side of my car. The noise only occurred if I went over terrain that caused the car to somewhat bounce up and down. I got out of the car. I discovered a metal bar hanging down near the left wheel. I then noticed another one hanging down near the right. The bars appear to be either ends of a long rod. These bars curve down away from that rod. One has a hole through the end. One has something like a nut or bolt on the end.

At 89,000 miles I replaced my plugs with autzone autolites and also replaced my fuel filter. Shortly there after the truck started to shutter and shake while miss firing giving a 0307 code. After checking that plug and replacing it, moving the COPs across the engine from each other the miss firing continued under the 0307 code. The miss firing mostly occurred when I was around 50 MPH, under slight strain with a little acceleration. If I powered through it most of the time it would clear out. Occasionally it was bad enough to where I had to pull over.
I trouble shot this for about a month before it got more consistent and worse. I took it to the shop where they tested the compression on the cylinder and also tested each coil. All check out OK. They recommended I replace all plugs with motorcrafts and the boots on the coils. In the process of doing that I discovered a loose plug in the #2 cylinder. I pulled it out and found that it was scorched and the metal was slightly tweaked at the tip. Not sure how it got loose or how it got burned, but figured that I found the problem. All plugs and boots replaced!
Two days later more miss firing. This time with a 0305 code. Occurs again on a grade at around 50 MPH with slight acceleration. I pulled that plug and the plug in the cylinder where the loose plug was found. Nothing seemed to be wrong. The plugs seemed a little brown where I put anti seize on but that I figured was normal. I then moved coils again. The miss fire continued and the code did not move. There is still a rough idle and occasional humming coming from the engine.
Is the loose burnt plug a separate issue or is there something causing all the miss fires that backed my plug out. I'm lost on my next step to take. Im getting married in two weeks so needless to say spending more and more money on this issue let alone time is making things so stressful. Besides the fact that I think my engine going to blow up on me every time it miss fires bad.

2012 v five with 56,500 miles. Getting onto an on ramp and accelerating when car jolted and dramatic power loss. I posted a thread about my car "ticking" as I slowed down from 30mph and I am wondering if this was related. I had no choice but to drive it home and kept car under 45 mostly on side streets. Car is not assisted at all by electric motor and can barely go up hills. With windows open and attention to any unusual sound i noticed no more ticking when slowing down from 25 to zero.... I think its covered under warranty at least powertrain, hopefully. I know a few of you here have the ticking problem to so i will update if this is related after i bring it in for service.

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.

Just recently, at 68,400 miles, the engine on my 2004 Dodge Sprinter stopped abruptly (on the freeway) and various instrument panel lights turned on. When we tried to start the van again, the instrument panel lights turned on again, and there was a humming coming from under the hood. After letting the van sit for awhile, it started normally, but the engine control unit light remained on. We took it in to a nearby Dodge dealer and the mechanic recommended replacing the fuel filter. We had the filter replaced.
The engine has not stopped abruptly anymore, however, when we try to start the van immediately after shutting it down, sometimes it will not start. Instrument panel lights light up and there is a humming coming from under the hood again. After letting the van sit for awhile longer, the van starts normally.
Previously, at 34,150 miles, the engine control unit light went on when the engine was started and stayed on for about 250 miles. The van drove normally during this time. The same thing happened at 59,100 miles and the light stayed on for about 250 miles again.
We take the Sprinter on long trips, and now we hold our breaths while starting the engine.

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.

I 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.

I have a 2011 f250 6.7, I park under my house everyday, so I am used to weird noises coming from my truck when I shut it off, but now that I just did a dpf and egr delete, and tuner, I noticed that my tuner doesn't shut down until the noise under the hood stops, which takes a few minutes to stop, I use to hear the air valve on the egr cooler shut when every got quiet, but I don't remember it lasting this long, any one else have a H&S mini max and it doesn't shut down right away? the place where I bought my mini maxx said it should shut down as soon as your head lights go out, but that's not the case, the headlights go out long before this noise stops and the tuner powers off
