Prius (2004-09) :: Noise At Start Before ICE Goes On And Splashing Sound
May 5, 2013
Prius makes all kinds of weird and almost funny noises; brake pump, electric motor hight pitch on braking and on ev mode.
I have 4 bare with me-questions:
When I start the car, before the ICE goes on, I hear a noise way back from drivers seat. Sounds like from back seat/trunk area. Sound is kind of pumping, low noise and goes on for maybe 3-5 seconds. Is it the gas pump? I have heard gas pumps before in cars on start and these is quite similar but louder
When I start engine cold(its around 5-10celsius now here on Finland, about 41-50 F), the ICE idles little uneven. RPM seems to be little waving, not much but audible up and down. I aint no expert but the rpm change is not big, maybe changing max 100-200 rounds up and down. Is this normal? My earlier car started cold in higher rpm but did not wave up and down.
Also to do with earlier question; when ICE is still cold( not freezing anyway) the first couple of stops at lights I very clearly feel a shudder. Keeping the brake pedal down and waiting on red light, the car shakes back and forth so that I feel it and even think someone standing outside car might even notice car trembling. Also ICE sounds abnormal at the same time; its not smooth sounding, kind of like misfiring, uneven sounding. Feels like gasoline is just about to go empty or car is stalling. Is this normal in "cold" weather? Heck, its not even below zero C here and car sounds like that.. waiting for winter and it gets -25 Celsius..

I bought a new 2015 Prius last week. Today, after I was cleaning only the tire/wheels cavity area by hosing it down with water. I heard a water splashing or sloshing sound when i was parking the car back in the garage when the car is moving. My theory is that the water still remains in some cavity in the car. So I will see if the noise is still there tomorrow when I go to work.

New to the prius world! I recently purchased a 06 prius with 185k. Gas engine needed to be replaced so I recently replaced it. Had code of engine failed to start. Now got replacement engine in and has p0300 and p0303 and p0304. Weird thing is new plugs. Swapped coils and injectors with same results. To me it sounds like a racket in the transmission. The noise is not consistent at all. Very loud and odd. Also inside the car when I put it in drive or neutral a warning light comes up and says shift to park batteries wont charge while in neutral.

I have a 2007 Prius that had a rotational noise on acceleration. I pinpointed the noise to the transmission area and suspected something was wrong with the electric motor. I took it to a local transmission shop and they disassembled the transmission to replace a bearing.
After repairs, they called me and informed me that the hybrid battery needed to be replaced. I've been driving the car for about a week with the noise and had no indication of a battery problem, or any other problem.
I had them tow the car back to my shop. The hybrid battery was discharged. The battery blocks were all between 10 and 12 volts. The vehicle would move slowly, but the ICE wouldn't start up to charge the battery. It had one DTC for hybrid battery malfunction.
I removed the battery from my own Prius and installed it in the car. The ICE fired up right away and shut off soon after, which would be completely normal in my car. But the engine never started again. I drove a short distance all on electric. The battery bars depleted quickly. Regen braking was not operating. There was a shudder every so often on acceleration. I'm not sure if it's in the transmission or the ICE is attempting to start? There are no DTCs so far.
The screen indicating where the power is going indicates that the engine is ON and delivering power even when it clearly is not. Not sure where to go with this one. It seems really odd that the ICE started once and won't start up. I tried disconnecting the battery and starting over, but the ICE still does not start up. I looked around the transmission for something disconnected, but found nothing.

I've got my "P1121" fix (replaced coolant control valve) recently and after about a week or so of driving (about 500 miles) I started to hear a gurgling sound at start up and sometimes when I turn the car off. I also noticed that pretty good amount of coolant (front side) was lost over the that same period of time (it wasn't losing coolant before for good 2k+ miles). I instantly filled the coolant and started the car. No gurgling then. But the gurgling came back after about 3 hours when I started it again. Car is not giving me any codes though.

My 2005 Prius shakes and makes a weird noise when I go to start it up in the morning. This usually only occurs from cold start in the mornings. Once I warm it up for ~2-3 mins all seems to be well. No CEL or anything of that nature. Trying to troubleshoot what the problem is with these cold startups. (76K)

We just replaced the inverter pump thinking this was the problem but it is still making noise. System has no air in it. What else can it be?

So I fill up my 2007 Sonata for the very first time. I'm squeezing the trigger on the pump, it clicks off automatically when it senses it's full, then about a pint of gas backs up out of the tank and onto the floor. Is there some sort of design flaw on the Sonata that causes this to happen? It could have been a problem with the pump, but I don't usually have that happen with my other cars.

My 2003 F150 extended cab (4x4, 4.6) won't take fuel without overflowing and splashing gas all over the place. Even if I run the pump at very low rate it still splashes back.
I replaced the tank last fall and it worked fine afterward for several months but the last few times I tried to fuel it I have had problems. I don't drive it too much so I only need to fuel it once a month or so.
Where I should start looking?

I have never noticed before but today I noticed the fluid inside the brake reservoir was bubbling or splashing around , whichever.What would cause this. I did just finish up on an intake manifold gasket replacement job. Drove for the first time today and that's when i noticed the 'bubbles'.

MY 2004 Prius is acting strange and wont start this morning. When I opened the door I got a beeping sound similar to the sound when you walk away with the key while the car is on. When I pressed power, the power seemed to only partially come on, the screen did not power on, and every warning light is on including the red triangle !. The car would not activate past that stage.

I have a 2012 Prius v (lowercase v for the Prius v wagon) with 20K miles on it. When you first start it up and sometimes when you turn it off it makes a squishing sound that sounds like an actuator in the break assembly doing something.

My vehicle is a 2004 XG350L with 120,900. I've got a clicking sound at start-up, especially in the cold, coming from the cam cover. It goes away after the engine is running for a while. What could possibly be causing this? How do I fix it?

My Honda Accord 2004 is making a whining sound when I start it up. It fades while driving buy it comes back every time the car accelerates from 1st to 2nd. It is an automatic but it is about that time frame that the sound occurs.
I've checked most things but am no expert. Transmission fluid, power steering, antifreeze, battery are all topped off and I just had an oil change (where I did use regular vs. synthetic which might be a factor but I don't know).
I also recently had the serpentine belt fixed but it sounds like the noise is coming from that area when the hood is up.

I recently had my oil changed at Toyota dealership at 11,700 miles. Picked it up after 2 days and upon starting heard a very loud rattling sound from engine; as if it were going to drop right out of the car. Shut it off and re-started ok, but very concerned. No repeat of incident until this morning. Same sound at start-up (now at 12,600 miles). My daughter who was inside the house could hear the noise. I used the car the previous day, parked outside in driveway as usual. Now very very concerned.

I have recently come across a strange problem. Only occurs after car has been turned off and sitting for 1-2 hours. Weather not affecting and sitting overnight, car starts normal and nice.
After the 1-2 hours of sitting, engine will turn over not the 2 or 3 usual times for ignition, but needing 10-12 times to finally start. Then it starts very poorly by making a sputtering sound and only idling at 200-500 rpms, instead of the usual instant 1000 rpms. This is very annoying and a few times the engine has turned over 10-12 times and didn't start at all. When a person starts the car up every 1 to 2 hours, say on a busy errand weekend, it pretty much occurs each time. When my wife uses the car just in the morning for work and at the end of the work day, it is not noticed for some reason....

I had the head gasket replaced along with all the other gaskets that come in the kit. new radiator, water pump, thermostat and thermostat gasket. blew head gasket at 78,000 miles. So now that has been taken care of, slowly everything else is going bad. recently, i pulled up in front of someones house and my suv turned off. When I tried to start it again it made a clanking sound and would not start. AAA'd it home and pulled the timing cover where the source of the sound was coming from. Seen the tensioner pulley loose and the belt loose. got it back on tdc and still does not start. the cranking over sound is lagging and sounds whiny. thought maybe was out of gas so i got gas and now when i try to start it it still is winding but it backfired and there was smoke behind the upper intake and still wont start. It wants to start, but doesn't.

I've got a 2004 Elantra, 4 Door Sedan. My wife drove it yesterday and parked it. She later attempted to start it, and it won't start. When she turns the key, the car makes whirring sound like it's about to start up and gets to the point just to where it should turn over, but never does. Lights come on, etc, so it appears it's not a battery issue. We're not super mechanically inclined, but sometimes things like this can be easy fixes.
On another quick note: her car had it's engine light come on a few weeks ago. Took it to the car parts store and read it as a catalytic convertor issue. It went away after she refilled up on gas, so we figured maybe it was some bad gas.
